1.	Bass, Gary Alan, 1979-, et al. (författare) Techniques for mesoappendix transection and appendix resection: insights from the ESTES SnapAppy study 2023 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Science and Business Media LLC. - 1863-9933 .- 1615-3146 .- 1863-9941. ; 49, s. 17-32 Tidskriftsartikel (refereegranskat)abstract Introduction: Surgically managed appendicitis exhibits great heterogeneity in techniques for mesoappendix transection and appendix amputation from its base. It is unclear whether a particular surgical technique provides outcome benefit or reduces complications. Material and methods: We undertook a pre-specified subgroup analysis of all patients who underwent laparoscopic appendectomy at index admission during SnapAppy (ClinicalTrials.gov Registration: NCT04365491). We collected routine, anonymized observational data regarding surgical technique, patient demographics and indices of disease severity, without change to clinical care pathway or usual surgeon preference. Outcome measures of interest were the incidence of complications, unplanned reoperation, readmission, admission to the ICU, death, hospital length of stay, and procedure duration. We used Poisson regression models with robust standard errors to calculate incident rate ratios (IRRs) and 95% confidence intervals (CIs). Results: Three-thousand seven hundred sixty-eight consecutive adult patients, included from 71 centers in 14 countries, were followed up from date of admission for 90days. The mesoappendix was divided hemostatically using electrocautery in 1564(69.4%) and an energy device in 688(30.5%). The appendix was amputated by division of its base between looped ligatures in 1379(37.0%), with a stapler in 1421(38.1%) and between clips in 929(24.9%). The technique for securely dividing the appendix at its base in acutely inflamed (AAST Grade 1) appendicitis was equally divided between division between looped ligatures, clips and stapled transection. However, the technique used differed in complicated appendicitis (AAST Grade 2 +) compared with uncomplicated (Grade 1), with a shift toward transection of the appendix base by stapler (58% vs. 38%; p < 0.001). While no statistical difference in outcomes could be detected between different techniques for division of appendix base, decreased risk of any [adjusted IRR (95% CI): 0.58 (0.41–0.82), p = 0.002] and severe [adjusted IRR (95% CI): 0.33 (0.11–0.96), p = 0.045] complications could be detected when using energy devices. Conclusions: Safe mesoappendix transection and appendix resection are accomplished using heterogeneous techniques. Technique selection for both mesoappendix transection and appendix resection correlates with AAST grade. Higher grade led to more ultrasonic tissue transection and stapled appendix resection. Higher AAST appendicitis grade also correlated with infection-related complication occurrence. Despite the overall well-tolerated heterogeneity of approaches to acute appendicitis, increasing disease acuity or complexity appears to encourage homogeneity of intraoperative surgical technique toward advanced adjuncts.

(författare) Mortality of trauma patients treated at trauma centers compared to non-trauma centers in Sweden: a retrospective study 2022 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Science and Business Media LLC. - 1863-9933 .- 1863-9941 .- 1615-3146. ; 48, s. 525-536 Tidskriftsartikel (refereegranskat)abstract Objective The main objective was to compare the 30-day mortality rate of trauma patients treated at trauma centers as compared to non-trauma centers in Sweden. The secondary objective was to evaluate how injury severity influences the potential survival benefit of specialized care. Methods This retrospective study included 29,864 patients from the national Swedish Trauma Registry (SweTrau) during the period 2013-2017. Three sampling exclusion criteria were applied: (1) Injury Severity Score (ISS) of zero; (2) missing data in any variable of interest; (3) data falling outside realistic values and duplicate registrations. University hospitals were classified as trauma centers; other hospitals as non-trauma centers. Logistic regression was used to analyze the effect of trauma center care on mortality rate, while adjusting for other factors potentially affecting the risk of death. Results Treatment at a trauma center in Sweden was associated with a 41% lower adjusted 30-day mortality (odds ratio 0.59 [0.50-0.70],p < 0.0001) compared to non-trauma center care, considering all injured patients (ISS >= 1). The potential survival benefit increased substantially with higher injury severity, with up to > 70% mortality decrease for the most critically injured group (ISS >= 50). Conclusions There exists a potentially substantial survival benefit for trauma patients treated at trauma centers in Sweden, especially for the most severely injured. This study motivates a critical review and possible reorganization of the national trauma system, and further research to identify the characteristics of patients in most need of specialized care.
3.	Forssten, Maximilian Peter, 1996-, et al. (författare) Surgical management of acute appendicitis during the European COVID-19 second wave: safe and effective 2023 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Science and Business Media LLC. - 1863-9933 .- 1615-3146 .- 1863-9941. ; 49, s. 57-67 Tidskriftsartikel (refereegranskat)abstract Introduction: The COVID-19 (SARS-CoV-2) pandemic drove acute care surgeons to pivot from long established practice patterns. Early safety concerns regarding increased postoperative complication risk in those with active COVID infection promoted antibiotic-driven non-operative therapy for select conditions ahead of an evidence-base. Our study assesses whether active or recent SARS-CoV-2 positivity increases hospital length of stay (LOS) or postoperative complications following appendectomy. Methods: Data were derived from the prospective multi-institutional observational SnapAppy cohort study. This preplanned data analysis assessed consecutive patients aged ≥ 15years who underwent appendectomy for appendicitis (November 2020–May 2021). Patients were categorized based on SARS-CoV-2 seropositivity: no infection, active infection, and prior infection. Appendectomy method, LOS, and complications were abstracted. The association between SARS-CoV-2 seropositivity and complications was determined using Poisson regression, while the association with LOS was calculated using a quantile regression model. Results: Appendectomy for acute appendicitis was performed in 4047 patients during the second and third European COVID waves. The majority were SARS-CoV-2 uninfected (3861, 95.4%), while 70 (1.7%) were acutely SARS-CoV-2 positive, and 116 (2.8%) reported prior SARS-CoV-2 infection. After confounder adjustment, there was no statistically significant association between SARS-CoV-2 seropositivity and LOS, any complication, or severe complications. Conclusion: During sequential SARS-CoV-2 infection waves, neither active nor prior SARS-CoV-2 infection was associated with prolonged hospital LOS or postoperative complication. Despite early concerns regarding postoperative safety and outcome during active SARS-CoV-2 infection, no such association was noted for those with appendicitis who underwent operative management.

(författare) The use of aortic balloon occlusion in traumatic shock : first report from the ABO trauma registry 2018 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Berlin/Heidelberg. - 1863-9933 .- 1863-9941 .- 1615-3146. ; 44:4, s. 491-501 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique for temporary stabilization of patients with non-compressible torso hemorrhage. This technique has been increasingly used worldwide during the past decade. Despite the good outcomes of translational studies, clinical studies are divided. The aim of this multicenter-international study was to capture REBOA-specific data and outcomes.METHODS: REBOA practicing centers were invited to join this online register, which was established in September 2014. REBOA cases were reported, both retrospective and prospective. Demographics, injury patterns, hemodynamic variables, REBOA-specific data, complications and 30-days mortality were reported.RESULTS: Ninety-six cases from 6 different countries were reported between 2011 and 2016. Mean age was 52 ± 22 years and 88% of the cases were blunt trauma with a median injury severity score (ISS) of 41 (IQR 29-50). In the majority of the cases, Zone I REBOA was used. Median systolic blood pressure before balloon inflation was 60 mmHg (IQR 40-80), which increased to 100 mmHg (IQR 80-128) after inflation. Continuous occlusion was applied in 52% of the patients, and 48% received non-continuous occlusion. Occlusion time longer than 60 min was reported as 38 and 14% in the non-continuous and continuous groups, respectively. Complications, such as extremity compartment syndrome (n = 3), were only noted in the continuous occlusion group. The 30-day mortality for non-continuous REBOA was 48%, and 64% for continuous occlusion.CONCLUSIONS: This observational multicenter study presents results regarding continuous and non-continuous REBOA with favorable outcomes. However, further prospective studies are needed to be able to draw conclusions on morbidity and mortality.

(författare) Physical therapists as first-line diagnosticians for traumatic acute rotator cuff tears : a prospective study 2018 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Science and Business Media LLC. - 1863-9933 .- 1863-9941. ; 44:5, s. 735-745 Tidskriftsartikel (refereegranskat)abstract Background: Early diagnosis of traumatic acute full-thickness rotator cuff tears (FTRCT) is important to offer early surgical repair. Late repairs following fatty infiltration of the rotator cuff muscles have less favorable results. We think that physical therapists are valuable diagnosticians in a screening process. The objective of this study was to evaluate the usefulness of physical therapists as first-line diagnosticians in detecting acute traumatic FTRCT. Methods: Between November 2010 and January 2014, 394 consecutive patients having an age between 18 and 75 years who sought medical care because of acute shoulder trauma with acute onset of pain, limited abduction and negative plain radiographs were included in the study. A clinical assessment was conducted by a physical therapist 1 week after the trauma. The patients were divided into three groups by the physical therapist according to the findings: FTRCT (Group I, n = 122); sprain (Group II, n = 62); or other specific diagnoses (Group III, n = 210). Group III patients were discharged and excluded from the study. Magnetic Resonance Imaging shoulder was performed for all Group I patients and for all patients with persistent symptoms in Group II. Results: 79/184 patients had FTRCTs documented by MRI in groups I and II. The clinical assessment of the physical therapist had a sensitivity of 85%, specificity of 68%, and usefulness index of 0.45 (> 0.35 considered useful) for diagnosing FTRCT. Conclusion: Physical therapists can be useful as first-line diagnosticians in detecting traumatic FTRCT.
6.	Aagaard, Knut E., et al. (författare) Return to work after early repair of acute traumatic rotator cuff tears 2020 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Science and Business Media LLC. - 1863-9933 .- 1863-9941. ; 46:4, s. 817-823 Tidskriftsartikel (refereegranskat)abstract Background: Lost workdays following rotator cuff repair is not well-studied in the literature. We aimed to define the time away from work following early arthroscopic repair of acute traumatic rotator cuff tears and compare it with the recommendations of the American Medical Disability Advisor (MD Guidelines) and The Swedish Social Insurance Agency. Methods: Thirty-two consecutive working patients with a median age of 58 (42–70) years suffering from acute traumatic rotator cuff tears who underwent arthroscopic repair were prospectively studied. The studied variables were age, gender, alcohol use, smoking, number of injured tendons, dominant side involvement, work-related injury, employment status, preoperative work level, alterations of work tasks at return to work, and time away from work. Results: 97% of the patients returned to full-duty work. The median time to return to full-duty work was 5.0 (1.1–10.5) months. Preoperative work level (p = 0.025) and dominant side (p = 0.02) significantly affected the time away from work on the univariate analysis, while GLM model showed a trend (p = 0.09) for shorter sick leave by dominant side involvement. The sick leave was longer in all three work level categories compared with the MD Guidelines and longer in the light and medium work categories compared with the recommendations by FK. Conclusions: According to the present study, acute traumatic rotator cuff tears cause a considerable loss of work days. However, almost all patients are expected to return to work after a median time of 5 months following arthroscopic repair. Current guidelines and recommendations regarding sick leave following repair of rotator cuff tears might have to be reviewed.
7.	Ahl, Rebecka, 1987-, et al. (författare) A nationwide observational cohort study of the relationship between beta-blockade and survival after hip fracture surgery 2022 Ingår i: European Journal of Trauma and Emergency Surgery. - : Urban und Vogel Medien und Medizin Verlagsgesellsc. - 1863-9933 .- 1863-9941. ; 48:2, s. 743-751 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Despite advances in the care of hip fractures, this area of surgery is associated with high postoperative mortality. Downregulating circulating catecholamines, released as a response to traumatic injury and surgical trauma, is believed to reduce the risk of death in noncardiac surgical patients. This effect has not been studied in hip fractures. This study aims to assess whether survival benefits are gained by reducing the effects of the hyper-adrenergic state with beta-blocker therapy in patients undergoing emergency hip fracture surgery.METHODS: This is a retrospective nationwide observational cohort study. All adults [Formula: see text] 18 years were identified from the prospectively collected national quality register for hip fractures in Sweden during a 10-year period. Pathological fractures were excluded. The cohort was subdivided into beta-blocker users and non-users. Poisson regression with robust standard errors and adjustments for confounders was used to evaluate 30-day mortality.RESULTS: 134,915 patients were included of whom 38.9% had ongoing beta-blocker therapy at the time of surgery. Beta-blocker users were significantly older and less fit for surgery. Crude 30-day all-cause mortality was significantly increased in non-users (10.0% versus 3.7%, p < 0.001). Beta-blocker therapy resulted in a 72% relative risk reduction in 30-day all-cause mortality (incidence rate ratio 0.28, 95% CI 0.26-0.29, p < 0.001) and was independently associated with a reduction in deaths of cardiovascular, respiratory, and cerebrovascular origin and deaths due to sepsis or multiorgan failure.CONCLUSIONS: Beta-blockers are associated with significant survival benefits when undergoing emergency hip fracture surgery. Outlined results strongly encourage an interventional design to validate the observed relationship.
8.	Ahl, Rebecka, 1987-, et al. (författare) β-Blocker after severe traumatic brain injury is associated with better long-term functional outcome : a matched case control study 2017 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Berlin/Heidelberg. - 1863-9933 .- 1863-9941. ; 43:6, s. 783-789 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Severe traumatic brain injury (TBI) is the predominant cause of death and disability following trauma. Several studies have observed improved survival in TBI patients exposed to β-blockers, however, the effect on functional outcome is poorly documented.METHODS: Adult patients with severe TBI (head AIS ≥ 3) were identified from a prospectively collected TBI database over a 5-year period. Patients with neurosurgical ICU length of stay <48 h and those dying within 48 h of admission were excluded. Patients exposed to β-blockers ≤ 48 h after admission and who continued with treatment until discharge constituted β-blocked cases and were matched to non β-blocked controls using propensity score matching. The outcome of interest was Glasgow Outcome Scores (GOS), as a measure of functional outcome up to 12 months after injury. GOS ≤ 3 was considered a poor outcome. Bivariate analysis was deployed to determine differences between groups. Odds ratio and 95% CI were used to assess the effect of β-blockers on GOS.RESULTS: 362 patients met the inclusion criteria with 21% receiving β-blockers during admission. After propensity matching, 76 matched pairs were available for analysis. There were no statistical differences in any variables included in the analysis. Mean hospital length of stay was shorter in the β-blocked cases (18.0 vs. 26.8 days, p < 0.01). The risk of poor long-term functional outcome was more than doubled in non-β-blocked controls (OR 2.44, 95% CI 1.01-6.03, p = 0.03).CONCLUSION: Exposure to β-blockers in patients with severe TBI appears to improve functional outcome. Further prospective randomized trials are warranted.

Andersson, Roland (författare) Evidence for improved outcome following use of hemostatic fibrin sealants in HPB surgery? 2012 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Science and Business Media LLC. - 1863-9933 .- 1863-9941. ; 38:1, s. 33-36 Forskningsöversikt (refereegranskat)abstract The development of fibrin sealants has been progressing; they are now often applied as fibrinogen-coated collagen patches. The concept has been increasingly applied in hepato-pancreato-biliary surgery, for example, following liver resection, and to some extent also in pancreatic surgery, both in order to reinforce the pancreatic anastomosis at pancreaticoduodenectomy and to seal the pancreatic stump following distal pancreatectomy. High quality evidence in the form of major prospective, randomized clinical studies is still lacking on in the field of HPB. There is also an the absence of proper cost-utility analyses.

12.	Bass, Gary Alan, 1979-, et al. (författare) European society for trauma and emergency surgery member-identified research priorities in emergency surgery : a roadmap for future clinical research opportunities 2024 Ingår i: European Journal of Trauma and Emergency Surgery. - : Urban und Vogel Medien und Medizin Verlagsgesellsc. - 1863-9933 .- 1863-9941. ; 50:2, s. 367-382 Forskningsöversikt (refereegranskat)abstract BACKGROUND: European Society for Trauma and Emergency Surgery (ESTES) is the European community of clinicians providing care to the injured and critically ill surgical patient. ESTES has several interlinked missions - (1) the promotion of optimal emergency surgical care through networked advocacy, (2) promulgation of relevant clinical cognitive and technical skills, and (3) the advancement of scientific inquiry that closes knowledge gaps, iteratively improves upon surgical and perioperative practice, and guides decision-making rooted in scientific evidence. Faced with multitudinous opportunities for clinical research, ESTES undertook an exercise to determine member priorities for surgical research in the short-to-medium term; these research priorities were presented to a panel of experts to inform a 'road map' narrative review which anchored these research priorities in the contemporary surgical literature.METHODS: Individual ESTES members in active emergency surgery practice were polled as a representative sample of end-users and were asked to rank potential areas of future research according to their personal perceptions of priority. Using the modified eDelphi method, an invited panel of ESTES-associated experts in academic emergency surgery then crafted a narrative review highlighting potential research priorities for the Society.RESULTS: Seventy-two responding ESTES members from 23 countries provided feedback to guide the modified eDelphi expert consensus narrative review. Experts then crafted evidence-based mini-reviews highlighting knowledge gaps and areas of interest for future clinical research in emergency surgery: timing of surgery, inter-hospital transfer, diagnostic imaging in emergency surgery, the role of minimally-invasive surgical techniques and Enhanced Recovery After Surgery (ERAS) protocols, patient-reported outcome measures, risk-stratification methods, disparities in access to care, geriatric outcomes, data registry and snapshot audit evaluations, emerging technologies interrogation, and the delivery and benchmarking of emergency surgical training.CONCLUSIONS: This manuscript presents the priorities for future clinical research in academic emergency surgery as determined by a sample of the membership of ESTES. While the precise basis for prioritization was not evident, it may be anchored in disease prevalence, controversy around aspects of current patient care, or indeed the identification of a knowledge gap. These expert-crafted evidence-based mini-reviews provide useful insights that may guide the direction of future academic emergency surgery research efforts.
13.	Bass, Gary Alan, 1979-, et al. (författare) Patterns of prevalence and contemporary clinical management strategies in complicated acute biliary calculous disease : an ESTES 'snapshot audit' of practice 2022 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 48, s. 23-25 Tidskriftsartikel (refereegranskat)abstract Background: Acute complications of biliary calculi are common, morbid, and complex to manage. Variability exists in the techniques utilized to treat these conditions at an individual surgeon and unit level.Aim: To identify, through an international prospective nonrandomized cohort study, the epidemiology and areas of practice variability in management of acute complicated calculous biliary disease (ACCBD) and to correlate them against reported outcomes.Methods: A preplanned analysis of the European Society of Trauma and Emergency Surgery (ESTES) 2018 Complicated Biliary Calculous Disease audit was performed. Patients undergoing emergency hospital admission with ACCBD between 1 October 2018 and 31 October 2018 were included. All eligible patients with acute complicated biliary calculous disease were recorded contemporaneously using a standardized predetermined protocol and a secure online database and followed-up through to 60 days from their admission.Endpoints: A two-stage data collection strategy collecting patient demographics, details of operative, endoscopic and radiologic intervention, and outcome metrics. Outcome measures included mortality, surgical morbidity, ICU stay, timing of operative intervention, and length of hospital stay.Results: Three hundred thirty-eight patients were included, with a mean age of 65 years and 54% were female. Diagnosis at admission were: cholecystitis (45.6%), biliary pancreatitis (21%), choledocholithiasis with and without cholangitis (13.9% and 18%). Index admission cholecystectomy was performed in just 50% of cases, and 28% had an ERCP performed. Morbidity and mortality were low.Conclusion: This first ESTES snapshot audit, a purely descriptive collaborative study, gives rich 'real world' insights into local variability in surgical practice as compared to international guidelines, and how this may impact upon outcomes. These granular data will serve to improve overall patient care as well as being hypothesis generating and inform areas needing future prospective study.
14.	Bass, Gary A, 1979-, et al. (författare) The snapshot audit methodology : design, implementation and analysis of prospective observational cohort studies in surgery 2023 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 49:1, s. 5-15 Tidskriftsartikel (refereegranskat)abstract Purpose: For some surgical conditionns and scientific questions, the "real world" effectiveness of surgical patient care may be better explored using a multi-institutional time-bound observational cohort assessment approach (termed a "snapshot audit") than by retrospective review of administrative datasets or by prospective randomized control trials. We discuss when this might be the case, and present the key features of developing, deploying, and assessing snapshot audit outcomes data.Methods: A narrative review of snapshot audit methodology was generated using the Scale for the Assessment of Narrative Review Articles (SANRA) guideline. Manuscripts were selected from domains including: audit design and deployment, statistical analysis, surgical therapy and technique, surgical outcomes, diagnostic testing, critical care management, concomitant non-surgical disease, implementation science, and guideline compliance.Results: Snapshot audits all conform to a similar structure: being time-bound, non-interventional, and multi-institutional. A successful diverse steering committee will leverage expertise that includes clinical care and data science, coupled with librarian services. Pre-published protocols (with specified aims and analyses) greatly helps site recruitment. Mentored trainee involvement at collaborating sites should be encouraged through manuscript contributorship. Current funding principally flows from medical professional organizations.Conclusion: The snapshot audit approach to assessing current care provides insights into care delivery, outcomes, and guideline compliance while generating testable hypotheses.

17.	Borger van der Burg, B. L. S., et al. (författare) A systematic review and meta-analysis of the use of resuscitative endovascular balloon occlusion of the aorta in the management of major exsanguination 2018 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Berlin/Heidelberg. - 1863-9933 .- 1863-9941. ; 44:4, s. 535-550 Forskningsöversikt (refereegranskat)abstract BACKGROUND: Circulatory collapse is a leading cause of mortality among traumatic major exsanguination and in ruptured aortic aneurysm patients. Approximately 40% of patients die before hemorrhage control is achieved. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an adjunct designed to sustain the circulation until definitive surgical or endovascular repair. A systematic review was conducted for the current clinical use of REBOA in patients with hemodynamic instability and to discuss its potential role in improving prehospital and in-hospital outcome.METHODS: Systematic review and meta-analysis (1900-2017) using MEDLINE, Cochrane, EMBASE, Web of Science and Central and Emcare using the keywords "aortic balloon occlusion", "aortic balloon tamponade", "REBOA", and "Resuscitative Endovascular Balloon Occlusion" in combination with hemorrhage control, hemorrhage, resuscitation, shock, ruptured abdominal or thoracic aorta, endovascular repair, and open repair. Original published studies on human subjects were considered.RESULTS: A total of 490 studies were identified; 89 met criteria for inclusion. Of the 1436 patients, overall reported mortality was 49.2% (613/1246) with significant differences (p < 0.001) between clinical indications. Hemodynamic shock was evident in 79.3%, values between clinical indications showed significant difference (p < 0.001). REBOA was favored as treatment in trauma patients in terms of mortality. Pooled analysis demonstrated an increase in mean systolic pressure by almost 50 mmHg following REBOA use.CONCLUSION: REBOA has been used in trauma patients and ruptured aortic aneurysm patients with improvement of hemodynamic parameters and outcomes for several decades. Formal, prospective study is warranted to clarify the role of this adjunct in all hemodynamic unstable patients.

(författare) Increased crystalloid fluid requirements during zone 3 Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) versus Abdominal Aortic and Junctional Tourniquet (AAJT) after class II hemorrhage in swine 2022 Ingår i: European journal of trauma and emergency surgery : official publication of the European Trauma Society. - : Springer Science and Business Media LLC. - 1863-9941. ; 48:1, s. 335-344 Tidskriftsartikel (refereegranskat)abstract PurposePelvic and lower junctional hemorrhage result in a significant amount of trauma related deaths in military and rural civilian environments. The Abdominal Aortic and Junctional Tourniquet (AAJT) and infra-renal (zone 3) Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) are two options for resuscitation of patients with life threatening blood loss from and distal to the pelvis. Evidence suggest differences in the hemodynamic response between AAJT and zone 3 REBOA, but fluid management during resuscitation with the devices has not been fully elucidated. We compared crystalloid fluid requirements (Ringer’s acetate) between these devices to maintain a carotid mean arterial pressure (MAP) > 60 mmHg.Methods60 kg anesthetized and mechanically ventilated male pigs were subjected to a mean 1030 (range 900–1246) mL (25% of estimated total blood volume, class II) haemorrhage. AAJT (n = 6) or zone 3 REBOA (n = 6) were then applied for 240 min. Crystalloid fluids were administered to maintain carotid MAP. The animals were monitored for 30 min after reperfusion.ResultsCumulative resuscitative fluid requirements increased 7.2 times (mean difference 2079 mL; 95% CI 627–3530 mL) in zone 3 REBOA (mean 2412; range 800–4871 mL) compared to AAJT (mean 333; range 0–1000 mL) to maintain target carotid MAP. Release of the AAJT required vasopressor support with norepinephrine infusion for a mean 9.6 min (0.1 µg/kg/min), while REBOA release required no vasopressor support.ConclusionZone 3 REBOA required 7.2 times more crystalloids to maintain the targeted MAP. The AAJT may therefore be considered in a situation of hemorrhagic shock to limit the need for crystalloid infusions, although removal of the AAJT caused more severe hemodynamic and metabolic effects which required vasopressor support.

All non-pathological olecranon fractures reported between 1 January 2014 and 31 December 2018 in patients aged ≥ 18 years were included. Data on age, sex, injury mechanism, fracture classification (according to the modified Mayo classification system), primary treatment and seasonal variation were analyzed. We compared patients < 65 with those > 65 years regarding injury mechanism, distribution of fracture types and subsequent treatment.Results: In total, 2462 olecranon fractures were identified in the SFR. Median age was 66 years and 65% were women. Of all fractures, 303 (12%) were proximal avulsion, 1044 (42%) simple central, 717 (29%) comminuted central and 398 (16%) distal olecranon fractures. Nonoperative treatment was performed in 21% of the patients < 65 and 35% of the patients > 65 years. Tension band wiring was used for most simple central fractures. Plate fixation was used in almost half of the operatively treated fractures classified as unstable comminuted central and distal olecranon fractures. Men show a higher proportion of high-energy trauma than women in both age groups.Conclusion: Isolated fractures of the olecranon occur after a low-energy trauma, especially in older women (> 65 years). Non-operative treatment is common in uncomplicated fractures and operative treatment in more complex fractures nationwide. A shift to plate fixation in the more unstable fracture patterns is observed. These results may help health care providers and clinicians gain a better understanding of isolated olecranon fractures.

(författare) Intermittent thoracic resuscitative endovascular balloon occlusion of the aorta improves renal function compared to 60 min continuous application after porcine class III hemorrhage 2023 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Berlin/Heidelberg. - 1863-9933 .- 1863-9941. ; 49:3, s. 1303-1313 Tidskriftsartikel (refereegranskat)abstract Background Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) may be considered for stabilization of patients with hemorrhage from below the diaphragm. Occluding the aorta is a powerful means of hemorrhagic control but is also associated with acute kidney injury, which increases mortality in trauma patients. Allowing for intermittent distal blood flow during REBOA application (iREBOA) could decrease this risk, but circulatory consequences have not been sufficiently elucidated. Therefore, we investigated circulatory effects and the renal artery blood flow (RBF) in iREBOA versus continuous, complete aortic occlusion (cREBOA).Methods In a porcine model of uncontrolled class III hemorrhage (34% estimated total blood volume, mean 1360 mL), swine (n = 12, mean weight 60.3 kg) were randomly assigned to iREBOA: 3-min full deflation every 10 min (n = 6), or cREBOA (n = 6), for 60 min of thoracic (zone I) application. The animals then underwent 60 min of reperfusion (critical care phase). Results Survival was 100% in iREBOA and 83% in cREBOA. The intermittent balloon deflation protocol was hemodynamically tolerable in 63% of reperfusion intervals. Systolic blood pressure decreased during the reperfusion intervals in iREBOA animals (mean 108 mm Hg versus 169 mm Hg; p < 0.005). No differences were detected in heart rate, cardiac output or stroke volume between methods. Troponin I increased in cREBOA after 60 min (mean 666-187 ng/L, p < 0.05). The norepinephrine requirement increased in cREBOA during reperfusion (mean infusion time 12.5-5.5 min; p < 0.05). Total ischemic time decreased in iREBOA (60.0-48.6 min; p < 0.001). RBF increased in iREBOA during balloon deflations and after 60 min reperfusion (61%-39% of baseline RBF; p < 0.05). Urine output increased in iREBOA (mean 135-17 mL; p < 0.001). Nephronal osteopontin, a marker of ischemic injury, increased in cREBOA (p < 0.05).Conclusion iREBOA was survivable, did not cause rebleeding, decreased the total ischemic time and increased the renal blood flow, urine output and decreased renal ischemic injury compared to cREBOA. Intermittent reperfusions during REBOA may be preferred to be continuous, complete occlusion in prolonged application to improve renal function.

(författare) Change in child mortality patterns after injuries in Sweden : a nationwide 14-year study. 2017 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 43:3, s. 343-349 Tidskriftsartikel (refereegranskat)abstract INTRODUCTION: Sweden has one of the world's lowest child injury mortality rates, but injuries are still the leading cause of death among children. Child injury mortality in the country has been declining, but this decline seems to decrease recently. Our objective was therefore to further examine changes in the mortality of children's death from injury over time and to assess the contribution of various effects on mortality. The underlying hypothesis for this investigation is that the incidence of lethal injuries in children, still is decreasing and that this may be sex specific.PATIENTS AND METHODS: We studied all deaths from injury in Sweden under-18-year-olds during the 14 years 1999-2012. We identified those aged under 18 whose underlying cause of death was recorded as International Classification of Diseases, 10th Revision (ICD-10) diagnosis from V01 to X39 in the Swedish cause of death, where all dead citizens are registered.RESULTS: From the 1 January 1999 to 31 December 2012, 1213 children under the age of 18 died of injuries in Sweden. The incidence declined during this period (r = -0.606, p = 0.02) to 3.3 deaths/100,000 children-years (95 % CI 2.6-4.2). Death from unintentional injury was more common than that after intentional injury (p < 0.0001). There was a reduction in the incidence of unintentional injuries during the study period (r = -0.757, p = 0.03). The most common causes of death were injury to the brain (n = 337, 41 %), followed by drowning (n = 109, 13 %). The number of deaths after intentional injury increased (r = 0.585, p = 0.03) and at the end of the period was 1.5 deaths/100,000 children-years. The most common causes of death after intentional injuries were asphyxia (n = 177, 45 %), followed by injury to the brain (n = 76, 19 %).DISCUSSION: Mortality patterns in injured children in Sweden have changed from being dominated by unintentional injuries to a more equal distribution between unintentional and intentional injuries as well as between sexes and the overall rate has declined further. These findings are important as they might contribute to the preventive work that is being done to further reduce mortality in injured children.

(författare) Deaths caused by injury among people of working age (18-64) are decreasing, while those among older people (64+) are increasing. 2018 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer Science and Business Media LLC. - 1863-9933 .- 1863-9941. ; 44:4, s. 589-596 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Injury is an important cause of death in all age groups worldwide, and contributes to many losses of human and economic resources. Currently, we know a few data about mortality from injury, particularly among the working population. The aim of the present study was to examine death from injury over a period of 14 years (1999-2012) using the Swedish Cause of Death Registry (CDR) and the National Patient Registry, which have complete national coverage.METHOD: CDR was used to identify injury-related deaths among adults (18 years or over) during the years 1999-2012. ICD-10 diagnoses from V01 to X39 were included. The significance of changes over time was analyzed by linear regression.RESULTS: The incidence of prehospital death decreased significantly (coefficient -0.22, r (2) = 0.30; p = 0.041) during the study period, while that of deaths in hospital increased significantly (coefficient 0.20, r (2) = 0.75; p < 0.001). Mortality/100,000 person-years in the working age group (18-64 years) decreased significantly (coefficient -0.40, r (2) = 0.37; p = 0.020), mainly as a result of decrease in traffic-related deaths (coefficient -0.34, r (2) = 0.85; p < 0.001). The incidence of deaths from injury among elderly (65 years and older) patients increased because of the increase in falls (coefficient 1.71, r (2) = 0.84; p < 0.001) and poisoning (coefficient 0.13, r (2) = 0.69; p < 0.001).CONCLUSION: The epidemiology of injury in Sweden has changed during recent years in that mortality from injury has declined in the working age group and increased among those people 64 years old and over.

The aim of this study was to determine the most common mechanisms of injury (MOI), injury patterns, and associated injuries in patients who undergo surgery for chest wall trauma. Methods: This was a retrospective study of trauma patients with multiple rib fractures and unstable thoracic cage injuries who were managed surgically at Sahlgrenska University Hospital during the period September 2010–September 2017. The MOI, injury severity score (ISS), new injury severity score (NISS), thoracic and associated injuries were recorded. Patients were categorized according to age (years): groups I (15‒44), II (45‒64) and III (> 64). Unstable thoracic cage injuries were classified as sternal, anterior, lateral and posterior flail chest. Results: Two hundred and eleven trauma patients with a mean age (years) of 58.2 ± 15.6, mean ISS 23.6 ± 11.0, and mean NISS 34.1 ± 10.6 were included in the study. Traffic accidents were the most common MOI in Group I (62%) and falls in Group III (59%). The most common flail segments were lateral and posterior. Sternal and anterior flail segments were more common with bilateral injuries and traffic accidents, particularly frontal collisions. Injuries in at least three body regions were also more associated with traffic accidents. Diaphragmatic injury was seen in 18% of patients who underwent thoracotomy. Conclusions: The MOI associated with multiple rib fractures differs according to the age of the patient and is associated with different chest wall injury patterns and extra-thoracic injuries. © 2019, The Author(s).

The cohort was cross-matched with the Swedish Hip Arthroplasty Register to obtain data on primary or secondary treatment with arthroplasty. We analysed data on age, sex, injury mechanism, fracture classification, treatment including secondary operative treatment with arthroplasty and mortality. Primary outcome was joint preservation.RESULTS: In total 47 Pipkin fractures with a median age of 48 years were included. 74% of the fractures were in males. The median follow-up time was 3.5 years. The most common primary treatment was internal fixation (45%), followed by primary arthroplasty (28%), and excision of fragment (15%). Three of the 34 patients with primary non arthroplasty treatment received secondary treatment with arthroplasty. Two patients died within 30 days, and no further deaths occurred up to 1 year after injury.CONCLUSION: Three of four fractures occurred in males and more than half of the fractures were due to high energetic injuries. Half of the patients received internal fixation (predominantly younger patients) and 28% were treated with primary arthroplasty (predominantly older patients). The revision rate was low, and after secondary treatment with arthroplasty two thirds of the patients still had a preserved joint.

While beta-blocker therapy (BBt) has shown a strong association with reduced postoperative mortality, its effect in frail patients has yet to be determined. This study's aim is to investigate how frailty, measured using the Orthopedic Hip Frailty Score (OFS), modifies the effect of preadmission beta-blocker therapy on mortality in hip fracture patients.METHODS: This retrospective register-based study included all adult patients in Sweden who suffered a traumatic hip fracture and subsequently underwent surgery between 2008 and 2017. Treatment effect was evaluated using the absolute risk reduction (ARR) in 30-day postoperative mortality when comparing patients with (BBt+) and without (BBt-) ongoing BBt. Inverse probability of treatment weighting (IPTW) was used to reduce potential confounding when examining the treatment effect. Patients were stratified based on their OFS (0, 1, 2, 3, 4 and 5) and the treatment effect was also assessed within each stratum.RESULTS: A total of 127,305 patients were included, of whom 39% had BBt. When IPTW was performed, there were no residual differences in observed baseline characteristics between the BBt+ and BBt- groups, across all strata. This analysis found that there was a stepwise increase in the ARRs for each additional point on the OFS. Non-frail BBt+ patients (OFS 0) exhibited an ARR of 2.2% [95% confidence interval (CI) 2.0-2.4%, p < 0.001], while the most frail BBt+ patients (OFS 5) had an ARR of 24% [95% CI 18-30%, p < 0.001], compared to BBt- patients within the same stratum.CONCLUSION: Beta-blocker therapy is associated with a reduced risk of 30-day postoperative mortality in frail hip fracture patients, with a greater effect being observed with higher Orthopedic Hip Frailty Scores.

The current study endeavors to describe the association between frailty, measured using the Orthopedic Frailty Score (OFS), and adverse outcomes in geriatric pelvic fracture patients.METHODS: All geriatric (65 years or older) patients registered in the 2013-2019 Trauma Quality Improvement Program database with an isolated pelvic fracture following blunt trauma were considered for inclusion. An isolated pelvic fracture was defined as any fracture in the pelvis with a lower extremity AIS ≥ 2, any abdomen AIS, and an AIS ≤ 1 in all other regions. Poisson regression models were employed to determine the association between the OFS and adverse outcomes.RESULTS: A total of 66,404 patients were included for further analysis. 52% (N = 34,292) were classified as non-frail (OFS 0), 32% (N = 21,467) were pre-frail (OFS 1), and 16% (N = 10,645) were classified as frail (OFS ≥ 2). Compared to non-frail patients, frail patients exhibited a 88% increased risk of in-hospital mortality [adjusted IRR (95% CI): 1.88 (1.54-2.30), p < 0.001], a 25% increased risk of complications [adjusted IRR (95% CI): 1.25 (1.10-1.42), p < 0.001], a 56% increased risk of failure-to-rescue [adjusted IRR (95% CI): 1.56 (1.14-2.14), p = 0.006], and a 10% increased risk of ICU admission [adjusted IRR (95% CI): 1.10 (1.02-1.18), p = 0.014].CONCLUSION: Frail pelvic fracture patients suffer from a disproportionately increased risk of mortality, complications, failure-to-rescue, and ICU admission. Additional measures are required to mitigate adverse events in this vulnerable patient population.

The aim of the current study was to determine if dementia functions as a surrogate for frailty, or if it confers additional information as a comorbidity when predicting postoperative mortality after a hip fracture.METHODS: All adult patients who suffered a traumatic hip fracture in Sweden between January 1, 2008 and December 31, 2017 were considered for inclusion. Pathological fractures, non-operatively treated fractures, reoperations, and patients missing data were excluded. Logistic regression (LR) models were fitted, one including and one excluding measurements of frailty, with postoperative mortality as the response variable. The primary outcome of interest was 30-day postoperative mortality. The relative importance for all variables was determined using the permutation importance. New LR models were constructed using the top ten most important variables. The area under the receiver-operating characteristic curve (AUC) was used to compare the predictive ability of these models.RESULTS: 121,305 patients were included in the study. Initially, dementia was among the top ten most important variables for predicting 30-day mortality. When measurements of frailty were included, dementia was replaced in relative importance by the ability to walk alone outdoors and institutionalization. There was no significant difference in the predictive ability of the models fitted using the top ten most important variables when comparing those that included [AUC for 30-day mortality (95% CI): 0.82 (0.81-0.82)] and excluded [AUC for 30-day mortality (95% CI): 0.81 (0.80-0.81)] measurements of frailty.CONCLUSION: Dementia functions as a surrogate for frailty when predicting mortality up to one year after hip fracture surgery. The presence of dementia in a patient without frailty does not appreciably contribute to the prediction of postoperative mortality.

(författare) Mortality risk stratification in isolated severe traumatic brain injury using the revised cardiac risk index 2022 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 48:6, s. 4481-4488 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Traumatic brain injury (TBI) continues to be a significant cause of mortality and morbidity worldwide. As cardiovascular events are among the most common extracranial causes of death after a severe TBI, the Revised Cardiac Risk Index (RCRI) could potentially aid in the risk stratification of this patient population. This investigation aimed to determine the association between the RCRI and in-hospital deaths among isolated severe TBI patients.METHODS: All adult patients registered in the TQIP database between 2013 and 2017 who suffered an isolated severe TBI, defined as a head AIS ≥ 3 with an AIS ≤ 1 in all other body regions, were included. Patients were excluded if they had a head AIS of 6. The association between different RCRI scores (0, 1, 2, 3, ≥ 4) and in-hospital mortality was analyzed using a Poisson regression model with robust standard errors while adjusting for potential confounders, with RCRI 0 as the reference.RESULTS: 259,399 patients met the study's inclusion criteria. RCRI 2 was associated with a 6% increase in mortality risk [adjusted IRR (95% CI) 1.06 (1.01-1.12), p = 0.027], RCRI 3 was associated with a 17% increased risk of mortality [adjusted IRR (95% CI) 1.17 (1.05-1.31), p = 0.004], and RCRI ≥ 4 was associated with a 46% increased risk of in-hospital mortality [adjusted IRR(95% CI) 1.46 (1.11-1.90), p = 0.006], compared to RCRI 0.CONCLUSION: An elevated RCRI ≥ 2 is significantly associated with an increased risk of in-hospital mortality among patients with an isolated severe traumatic brain injury. The simplicity and bedside applicability of the index makes it an attractive choice for risk stratification in this patient population.

The Revised Cardiac Risk Index (RCRI) is a tool used to evaluate the 30-day risk of, among other outcomes, post-operative mortality. The aim of this study is to determine the association between the RCRI score and post-operative mortality in patients undergoing hip fracture surgery.METHODS: Data was obtained from the national hip fracture register which was cross-referenced with patients' electronic hospital records. All adults who underwent primary emergency hip fracture surgery in Orebro County, Sweden, between January 1, 2013 and December 31, 2017, were included. Patients were divided into two cohorts: low RCRI (score = 0-1) and high RCRI (score ≥ 2). A Poisson regression model was employed to investigate the association between a high RCRI score and 30- and 90-day post-operative mortality.RESULTS: A total of 2443 patients, of whom 446 (18%) had a high RCRI score, were included in the current study. When adjusting for age, sex, comorbidities and type of surgery, the incidence of 30-day mortality increased by 46% in the high RCRI cohort (adj. IRR 1.46, 95% CI, 1.10-1.94, p = 0.010). Similar results were observed for 90-day mortality (adj. IRR 1.50, 95% CI, 1.21-1.84, p < 0.001).CONCLUSION: The RCRI is applicable to patients that undergo surgery for traumatic hip fractures. A high RCRI score is associated with an increased incidence of both 30- and 90-day post-operative mortality. Future studies to evaluate these findings are needed.

Furthermore, internal fixation and arthroplasty were compared to determine if a difference could be observed in patients operated with these techniques at different times during the day.METHODS: All patients above 18 of age years in Sweden who underwent hip fracture surgery between 2008 and 2017 were eligible for inclusion. Pathological fractures, non-operatively managed fractures, or cases whose time of surgery was missing were excluded. The cohort was subdivided into on-hour (08:00-17:00) and out-of-hours surgery (17:00-08:00). Poisson regression with adjustments for confounders was used to evaluate the association between out-of-hours surgery and both 30-day and 90-day postoperative mortality.RESULTS: Out-of-hours surgery was associated with a 5% increase in the risk of both 30-day [adj. IRR (95% CI) 1.05 (1.00-1.10), p = 0.040] and 90-day [adj. IRR (95% CI) 1.05 (1.01-1.09), p = 0.005] mortality after hip fracture surgery compared to on-hour surgery. There was no statistically significant association between out-of-hours surgery and postoperative mortality among patients who received an internal fixation. Arthroplasties performed out-of-hours were associated with a 13% increase in 30-day postoperative mortality [adj. IRR (95% CI) 1.13 (1.04-1.23), p = 0.005] and an 8% increase in 90-day postoperative mortality [adj. IRR (95% CI) 1.08 (1.01-1.15), p = 0.022] compared to on-hour surgery.CONCLUSION: Out-of-hours surgical intervention is associated with an increase in both 30- and 90-day postoperative mortality among hip fracture patients who received an arthroplasty, but not among patients who underwent internal fixation.

(författare) The mortality burden of frailty in hip fracture patients : a nationwide retrospective study of cause-specific mortality 2023 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 49:3, s. 1467-1475 Tidskriftsartikel (refereegranskat)abstract Purpose: Frailty is a condition characterized by a reduced ability to adapt to external stressors because of a reduced physiologic reserve, which contributes to the high risk of postoperative mortality in hip fracture patients. This study aims to investigate how frailty is associated with the specific causes of mortality in hip fracture patients.Methods: All adult patients in Sweden who suffered a traumatic hip fracture and underwent surgery between 2008 and 2017 were eligible for inclusion. The Orthopedic Hip Frailty Score (OFS) was used to classify patients as non-frail (OFS 0), pre-frail (OFS 1), and frail (OFS & GE; 2). The association between the degree of frailty and both all-cause and cause-specific mortality was determined using Poisson regression models with robust standard errors and presented using incidence rate ratios (IRRs) with corresponding 95% confidence intervals (CIs), adjusted for potential sources of confounding.Results: After applying the inclusion and exclusion criteria, 127,305 patients remained for further analysis. 23.9% of patients were non-frail, 27.7% were pre-frail, and 48.3% were frail. Frail patients exhibited a 4 times as high risk of all-cause mortality 30 days [adj. IRR (95% CI): 3.80 (3.36-4.30), p < 0.001] and 90 days postoperatively [adj. IRR (95% CI): 3.88 (3.56-4.23), p < 0.001] as non-frail patients. Of the primary causes of 30-day mortality, frailty was associated with a tripling in the risk of cardiovascular [adj. IRR (95% CI): 3.24 (2.64-3.99), p < 0.001] and respiratory mortality [adj. IRR (95% CI): 2.60 (1.96-3.45), p < 0.001] as well as a five-fold increase in the risk of multiorgan failure [adj. IRR (95% CI): 4.99 (3.95-6.32), p < 0.001].Conclusion: Frailty is associated with a significantly increased risk of all-cause and cause-specific mortality at 30 and 90 days postoperatively. Across both timepoints, cardiovascular and respiratory events along with multiorgan failure were the most prevalent causes of mortality.

(författare) Validation of the orthopedic frailty score for measuring frailty in hip fracture patients : a cohort study based on the United States National inpatient sample 2023 Ingår i: European Journal of Trauma and Emergency Surgery. - : Urban und Vogel Medien und Medizin Verlagsgesellsc. - 1863-9933 .- 1863-9941. ; 49:5, s. 2155-2163 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: The Orthopedic Frailty Score (OFS) has been proposed as a tool for measuring frailty in order to predict short-term postoperative mortality in hip fracture patients. This study aims to validate the OFS using a large national patient register to determine its relationship with adverse outcomes as well as length of stay and cost of hospital stay.METHODS: All adult patients (18 years or older) registered in the 2019 National Inpatient Sample Database who underwent emergency hip fracture surgery following a traumatic fall were eligible for inclusion. The association between the OFS and mortality, complications, and failure-to-rescue (FTR) was determined using Poisson regression models adjusted for potential confounders. The relationship between the OFS and length of stay and cost of hospital stay was instead determined using a quantile regression model.RESULTS: An estimated 227,850 cases met the study inclusion criteria. There was a stepwise increase in the rate of complications, mortality, and FTR for each additional point on the OFS. After adjusting for potential confounding, OFS 4 was associated with an almost ten-fold increase in the risk of in-hospital mortality [adjusted IRR (95% CI): 10.6 (4.02-27.7), p < 0.001], a 38% increased risk of complications [adjusted IRR (95% CI): 1.38 (1.03-1.85), p = 0.032], and an almost 11-fold increase in the risk of FTR [adjusted IRR (95% CI): 11.6 (4.36-30.9), p < 0.001], compared to OFS 0. Patients with OFS 4 also required a day and a half additional care [change in median length of stay (95% CI): 1.52 (0.97-2.08), p < 0.001] as well as cost approximately $5,200 more to manage [change in median cost of stay (95% CI): 5166 (1921-8411), p = 0.002], compared to those with OFS 0.CONCLUSION: Patients with an elevated OFS display a substantially increased risk of mortality, complications, and failure-to-rescue as well as a prolonged and more costly hospital stay.

(författare) Epidemiology and treatment of pediatric tibial fractures in Sweden : a nationwide population-based study on 5828 fractures from the Swedish Fracture Register 2023 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 49:2, s. 911-919 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Pediatric tibial fractures have been described internationally as mainly caused by fall during leisure activities and organized sports and showing a higher incidence in boys. Still, most studies are single center studies or have a small sample size. This study aimed to analyze sex and age distribution, seasonal variation, injury mechanisms and treatment of pediatric tibial fractures based on the nationwide Swedish Fracture Register (SFR).METHODS: All tibial fractures in patients < 16 years at injury and registered in 2015-2019 were extracted from the SFR. We analyzed patient characteristics such as sex and age, injury mechanism, fracture location and treatment.RESULTS: The study cohort consisted of 5828 pediatric tibial fractures in 5719 patients. Median age of the patients was 7 years and 58% were boys. Shaft fractures were most common, followed by the distal and proximal tibia. The lowest incidence was observed during autumn. The most common cause of injury was fall mostly involving winter sports, stumbles and fall from play equipment. Play/free time and sports were the most common activities, common places of injury were sports facility and home. 1% were open fractures. 78% were treated non-surgically. Screw fixation was performed in 52% of surgically treated fractures, predominantly in the distal segment.CONCLUSION: Injury mechanism differs between age groups; play/free time injuries are common in younger children compared with sport activities in older children. Most patients are treated non-surgically. Open fractures are rare. Information on injury patterns is useful working preventively, for example safety work in playgrounds.

Tidskriftsartikel (refereegranskat)abstract There is a need for implementation and maturation of an inclusive trauma system in every country in Europe, with patient centered care by dedicated surgeons. This process should be initiated by physicians and medical societies, based on the best available evidence, and supported and subsequently funded by the government and healthcare authorities. A systematic approach to organizing all aspects of trauma will result in health gain in terms of quality of care provided, higher survival rates, better functional outcomes and quality of life. In addition, it will provide reliable data for both research, quality improvement and prevention programs. Severely injured patients need surgeons with broad technical and non-technical competencies to provide holistic, inclusive and compassionate care. Here we describe the philosophy of the surgical approach and define the necessary skills for trauma, both surgical and other, to improve outcome of severely injured patients. As surgery is an essential part of trauma care, surgeons play an important role for the optimal treatment of trauma patients throughout and after their hospital stay, including the intensive care unit (ICU). However, in most European countries, it might not be obvious to either the general public, patients or even the physicians that the surgeon must assume this responsibility in the ICU to optimize outcomes. The aim of this paper is to define key elements in terms of trauma systems, trauma-specific surgical skills and active critical care involvement, to organize and optimize trauma care in Europe.

(författare) Validation of the Swedish Trauma Registry (SweTrau) 2023 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 49:4, s. 1627-1637 Tidskriftsartikel (refereegranskat)abstract PurposeValidation of registries is important to ensure accuracy of data and registry-based research. This is often done by comparisons of the original registry data with other sources, e.g. another registry or a re-registration of data. Founded in 2011, the Swedish Trauma Registry (SweTrau) consists of variables based on international consensus (the Utstein Template of Trauma). This project aimed to perform the first validation of SweTrau.MethodsOn-site re-registration was performed on randomly selected trauma patients and compared to the registration in SweTrau. Accuracy (exact agreement), correctness (exact agreement plus data within acceptable range), comparability (similarity with other registries), data completeness (1-missing data) and case completeness (1-missing cases) were deemed as either good (≥85%), adequate (70–84%) or poor (< 70%). Correlation was determined as either excellent (≥0.8), strong (0.6–0.79), moderate (0.4–0.59) or weak (< 0.4).ResultsThe data in SweTrau had good accuracy (85.8%), correctness (89.7%) and data completeness (88.5%), as well as strong or excellent correlation (87.5%). Case completeness was 44.3%, however, for NISS > 15 case completeness was 100%. Median time to registration was 4.5 months, with 84.2% registered one year after the trauma. The comparability showed an accordance with the Utstein Template of Trauma of almost 90%.ConclusionsThe validity of SweTrau is good, with high accuracy, correctness, data completeness and correlation. The data are comparable to other trauma registries using the Utstein Template of Trauma; however, timeliness and case completeness are areas of improvement.

(författare) A small case series of aortic balloon occlusion in trauma : lessons learned from its use in ruptured abdominal aortic aneurysms and a brief review 2016 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 42:5, s. 585-592 Forskningsöversikt (refereegranskat)abstract EndoVascular and Hybrid Trauma Management (EVTM) is an emerging concept for the early treatment of trauma patients using aortic balloon occlusion (ABO), embolization agents and stent grafts to stop ongoing traumatic bleeding. These techniques have previously been implemented successfully in the treatment of ruptured aortic aneurysm.We describe our very recent experience of EVTM using ABO in bleeding patients and lessons learned over the last 20 years from the endovascular treatment of ruptured abdominal aortic aneurysms (rAAA). We also briefly describe current knowledge of ABO usage in trauma.A small series of educational cases in our hospital is described, where endovascular techniques were used to gain temporary hemorrhage control. The methods used for rAAA and their applicability to EVTM with a multidisciplinary approach are presented.Establishing femoral arterial access immediately on arrival at the emergency room and use of an angiography table in the surgical suite may facilitate EVTM at an early stage. ABO may be an effective method for the temporary stabilization of severely hemodynamically unstable patients with hemorrhagic shock, and may be useful as a bridge to definitive treatment of the bleeding patients.EVTM, including the usage of ABO, can be initiated on patient arrival and is feasible. Further data need to be collected to investigate proper indications for ABO, best clinical usage, results and potential complications. Accordingly, the ABOTrauma Registry has recently been set up. Existing experiences of EVTM and lessons from the endovascular treatment of rAAA may be useful in trauma management.

(författare) Surgical management of displaced femoral neck fractures in patients with dementia : a comparison in mortality between hemiarthroplasty and pins/screws 2022 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 48:2, s. 1151-1158 Tidskriftsartikel (refereegranskat)abstract INTRODUCTION: Dementia is common in patients with hip fractures and is strongly associated with increased postoperative mortality. The choice of surgical intervention for displaced femoral neck fractures (dFNF) in patients with dementia has been a matter of debate. This study aims to investigate how short- and long-term mortality differs between those who have been operated with hemiarthroplasty or pins/screws.METHODS: All patients with dementia and dFNF, i.e., Garden III and IV, who underwent primary emergency hip fracture surgery, with either hemiarthroplasty or pins/screws, in Sweden between Jan 1, 2008 and Dec 31, 2017 were eligible for inclusion in the current study. Patients were divided into two groups based on the surgical intervention: hemiarthroplasty and pins/screws. The primary outcome of interest was 30-day postoperative mortality, and the secondary outcome was 1-year postoperative mortality. Poisson and Cox regression analyses were performed both before and after propensity score matching.RESULTS: A total of 9394 cases met the inclusion criteria; 84% received hemiarthroplasty and 16% received pins/screws. In the unmatched analysis, the adjusted incidence rate ratio (IRR) for 30-day postoperative mortality was not affected by the chosen surgical method (adj. IRR 0.96, CI 95% 0.83-1.12, p = 0.629). After propensity score matching, similar results were observed with no difference in 30-day postoperative mortality (adj. IRR 0.89, CI 95% 0.74-1.09, p = 0.286). There was a statistically significant decrease in the risk of 1-year postoperative mortality in the hemiarthroplasty group compared to the pins/screws group, both before and after propensity score matching.CONCLUSION: This study could not demonstrate any difference in 30-day mortality in patients with dementia and dFNFs when comparing hemiarthroplasty with pins/screws. Patients that received hemiarthroplasties did, however, have a lower risk of 1-year postoperative mortality.
44.	Ioannidis, Ioannis, 1967-, et al. (författare) The mortality burden in patients with hip fractures and dementia 2022 Ingår i: European Journal of Trauma and Emergency Surgery. - : Urban und Vogel Medien und Medizin Verlagsgesellsc. - 1863-9933 .- 1863-9941. ; 48:4, s. 2919-2952 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Dementia is strongly associated with postoperative death in patients subjected to hip fracture surgery. Nevertheless, there is a distinct lack of research investigating the cause of postoperative mortality in patients with dementia. This study aims to investigate the distribution and the risk of cause-specific postoperative mortality in patients with dementia compared to the general hip fracture population.METHODS: All adults who underwent emergency hip fracture surgery in Sweden between 1/1/2008 and 31/12/2017 were considered for inclusion. Pathological, conservatively managed fractures, and reoperations were excluded. The database was retrieved by cross-referencing the Swedish National Quality Registry for Hip Fracture patients with the Swedish National Board of Health and Welfare quality registers. A Poisson regression model was used to determine the association between dementia and all-cause as well as cause-specific 30-day postoperative mortality.RESULTS: 134,915 cases met the inclusion criteria, of which 20% had dementia at the time of surgery. The adjusted risk of all-cause 30-day postoperative mortality was 67% higher in patients with dementia after hip fracture surgery compared to patients without dementia [adj. IRR (95% CI): 1.67 (1.60-1.75), p < 0.001]. The risk of cause-specific mortality was also higher in patients with dementia, with up to a sevenfold increase in the risk cerebrovascular mortality [adj. IRR (95% CI): 7.43 (4.99-11.07), p < 0.001].CONCLUSIONS: Hip fracture patients with dementia have a higher risk of death in the first 30 days postoperatively, with a substantially higher risk of mortality due to cardiovascular, respiratory, and cerebrovascular events, compared to patients without dementia.
45.	Ioannidis, Ioannis, 1967-, et al. (författare) The relationship and predictive value of dementia and frailty for mortality in patients with surgically managed hip fractures 2024 Ingår i: European Journal of Trauma and Emergency Surgery. - : Urban und Vogel Medien und Medizin Verlagsgesellsc. - 1863-9933 .- 1863-9941. ; 50:2, s. 339-345 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Both dementia and frailty have been associated with worse outcomes in patients with hip fractures. However, the interrelation and predictive value of these two entities has yet to be clarified. The current study aimed to investigate the predictive relationship between dementia, frailty, and in-hospital mortality after hip fracture surgery.METHODS: All patients registered in the 2019 National Inpatient Sample Database who were 50 years or older and underwent emergency hip fracture surgery following a traumatic fall were eligible for inclusion. Logistic regression (LR) models were constructed with in-hospital mortality as the response variables. One model was constructed including markers of frailty and one model was constructed excluding markers of frailty [Orthopedic Frailty Score (OFS) and weight loss]. The feature importance of all variables was determined using the permutation importance method. New LR models were then fitted using the top ten most important variables. The area under the receiver-operating characteristic curve (AUC) was used to compare the predictive ability of these models.RESULTS: An estimated total of 216,395 patients were included. Dementia was the 7th most important variable for predicting in-hospital mortality. When the OFS and weight loss were included, they replaced dementia in importance. There was no significant difference in the predictive ability of the models when comparing the model that included markers of frailty [AUC for in-hospital mortality (95% CI) 0.79 (0.77-0.81)] with the model that excluded markers of frailty [AUC for in-hospital mortality (95% CI) 0.79 (0.77-0.80)].CONCLUSION: Dementia functions as a surrogate for frailty when predicting in-hospital mortality in hip fracture patients. This finding highlights the importance of early frailty screening for improvement of care pathways and discussions with patients and their families in regard to expected outcomes.

(författare) β-Adrenergic blockade in patients with dementia and hip fracture is associated with decreased postoperative mortality 2022 Ingår i: European Journal of Trauma and Emergency Surgery. - : Springer. - 1863-9933 .- 1863-9941. ; 48:2, s. 1463-1469 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Dementia, present in 20% of hip fracture patients, is associated with an almost threefold increase in postoperative mortality risk. These patients have a substantially higher incidence of cardiovascular, respiratory, and cerebrovascular mortality after hip fracture surgery compared to patients without dementia. This study aimed to investigate the association between beta-blocker therapy and postoperative mortality in patients with dementia undergoing hip fracture surgery.METHODS: This nationwide study included all patients in Sweden with the diagnosis of dementia who underwent emergency surgery for a hip fracture between January 2008 and December 2017. Cases where the hip fracture was pathological or conservatively managed were not included. Poisson regression analysis with robust standard errors was performed while controlling for confounders to determine the relationship between beta-blocker therapy and all-cause, as well as cause-specific, postoperative mortality.RESULTS: A total of 26,549 patients met the study inclusion criteria, of whom 8258 (31%) had ongoing beta-blocker therapy at time of admission. After adjusting for clinically relevant variables, the incidence of postoperative mortality in patients receiving beta-blocker therapy was decreased by 50% at 30 days [adj. IRR (95% CI) 0.50 (0.45-0.54), p < 0.001] and 34% at 90 days [adj. IRR (95% CI) 0.66 (0.62-0.70), p < 0.001]. Cause-specific mortality analysis demonstrated a significant reduction in the incidence of postoperative cardiovascular, respiratory, and cerebrovascular death within 30 and 90 days postoperatively.CONCLUSION: Beta-blocker therapy is associated with decreased postoperative mortality in hip fracture patients with dementia up to 90 days after surgery. This finding warrants further investigation.

One hundred and nine consecutive patients with small bowel obstruction who underwent small bowel follow-through examination with Gastrografin(A (R)) during 2005-2006. The patients were divided into an operative group and a non-operative group, n = 44 and 65, respectively. Findings primarily noted were those which were possible to register within 1-4 h from hospital arrival. In univariate analyses, factors found to be significantly associated with surgical intervention were no prior abdominal surgery, the presence of radiological differential air fluid levels, and absence of flatulence 24 h prior to admission, CRP > 10 mg/L and dehydration at admission. In multivariate analyses, the presence of dehydration and radiological differentiated air fluid levels were independent predictive factors of significance. Absence of all factors significantly favored non-operative treatment, while operative treatment was significantly favored when two or more factors were present. The presence of two or more early predictive factors as defined above, available at admission, significantly correlates with a likelihood of complete obstruction and the need of surgical intervention.

The purpose of this study was to identify facilitators and constrainers in CMC in a national perspective with a specific focus on medical aspects.MethodA literature review of recently published papers about civilian–military collaboration, along with a short survey, was conducted. For the review, major search engines were used.ResultsThe results indicated many facilitators, but few important constrainers with a high impact on the outcome. The conducted survey indicated discrepancies between the needs and resources.ConclusionThe current global and domestic security threats and challenges, make CMC critical and inevitable. However, there is a need for careful analysis of its consequences, impact, possibilities, and limitations to differentiate between our expectations and the current reality.

The purpose of this study was to identify these measures and the public's willingness to conduct them.An extensive literature review was performed to identify the possible measures that can be undertaken by the public. A group of experts were asked to prioritize and rank the feasibility of performing the measures by the public. Finally, the public was asked whether they were willing to do the chosen measures before and after an appropriate education.Twenty different measures were identified and presented in a questionnaire as statements, which were prioritized and ranked by the expert group into four categories: what (1) should be done, (2) is good to know how, (3) is not necessary to know, and (4) should not be done. All statements were converted into understandable statements and were sent to the public. There were some differences and some agreements between the experts and the public regarding what an immediate responder should do. However, the willingness of the public to perform most of the measures was high and increased after being offered an appropriate education.The use of immediate responders is a life-saving approach in MCIs and in situations when every minute counts and every human resource is an invaluable asset. Multiple steps, such as education, empowerment, and access, should be taken into consideration to enable bystanders to effectively help struggling survivors.

Recent experiences from terrorist attacks worldwide have resulted in a search for better assessment of the needs, resources, and knowledge in the medical and non-medical management of these incidents and also actualized the need for collaboration between civilian and military healthcare. The aim of this study was to evaluate the impact of the civilian-military collaboration in a Swedish context with the main focus on its non-medical management.An exercise, simulating a foreign military attack centrally on Swedish soil, was designed, initiated, and conducted by a team consisting of civilian and military staff. Data were collected prospectively and evaluated by an expert team.Specific practical and technical issues were presented in collaboration between civilian and military staffs. In addition, shortcomings in decision-making, follow-up, communication, and collaboration due to prominent lack of training and exercising the tasks and positions in all managerial levels of the hospital were identified.Current social and political unrests and terror attacks worldwide necessitate civilian-military collaboration. Such collaboration, however, needs to be synchronized and adjusted to avoid preventable medical and non-medical consequences. Simulation exercises might be one important source to improve such collaboration.
