Journal article (peer-reviewed)abstract
- OBJECTIVE: To study characteristics and outcomes among patients with in-hospital cardiac arrest (IHCA) due to pulmonary aspiration.DESIGN: A retrospective observational study based on data from the Swedish Registry of Cardiopulmonary Resuscitation (SRCR).SETTING: The SRCR is a nationwide quality registry that covers 96% of all Swedish hospitals. Participating hospitals vary in size from secondary hospitals to university hospitals.PARTICIPANTS: The study included patients registered in the SRCR in the period 2008 to 2017. We compared patients with IHCA caused by pulmonary aspiration (n=127), to those with IHCA caused by respiratory failure of other causes (n=2197).PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome was 30-day survival. Secondary outcome was sustained return of spontaneous circulation (ROSC) defined as ROSC at the scene and admitted alive to the intensive care unit.RESULTS: In the aspiration group 80% of IHCA occurred on general wards, as compared with 63.6% in the respiratory failure group (p<0.001). Patients in the aspiration group were less likely to be monitored at the time of the arrest (18.5% vs 38%, p<0.001) and had a significantly lower rate of sustained ROSC (36.5% vs 51.6%, p=0.001). The unadjusted 30-day survival rate compared with the respiratory failure group was 7.9% versus 18.0%, p=0.024. In a propensity score analysis (including variables; year, age, gender, location of arrest, initial heart rhythm, ECG monitoring, witnessed collapse and a previous medical history of; cancer, myocardial infarction or heart failure) the OR for 30-day survival was 0.46 (95% CI 0.19 to 0.94).CONCLUSIONS: In-hospital cardiac arrest preceded by pulmonary aspiration occurred more often on general wards among unmonitored patients. These patients had a lower 30-day survival rate compared with IHCA caused by respiratory failure of other causes.

Journal article (peer-reviewed)abstract
- BACKGROUND: The selection for surgery is multifaceted for patients diagnosed with esophageal cancer. Since it is uncertain how comorbidity should influence the selection, this study addressed comorbidities in relation to risk of severe complications following esophageal cancer surgery.METHODS: This population-based cohort study was based on prospectively included patients who underwent surgical resection for an esophageal or gastro-esophageal junctional cancer in Sweden during 2001-2005. The participation rate was 90%. Associations between pre-defined comorbidities and pre-defined post-operative complications occurring within 30 days of surgery were analyzed using multivariable logistic regression. The resulting odds ratios (ORs) and 95% confidence intervals (CIs) were adjusted for age, sex, tumor stage, tumor histology, neoadjuvant therapy, type of surgery, annual hospital volume, other comorbidities, and other complications.RESULTS: Among 609 included patients, those with cardiac disease (n = 92) experienced an increased risk of pre-defined complications in general (adjusted OR 1.81, 95% CI 1.13-2.90), while patients with hypertension (n = 137), pulmonary disorders (n = 79), diabetes (n = 67), and obesity (n = 66) did not. Patients with a Charlson comorbidity index score ≥2 had substantially increased risks of pre-defined complications (adjusted OR 2.44, 95% CI 1.60-3.72).CONCLUSION: Cardiac disease and a Charlson comorbidity index score ≥2 seem to increase the risk of severe and early post-operative complications in patients with esophageal cancer, while hypertension, pulmonary disorders, diabetes, and obesity do not. These findings should be considered in the clinical decision-making for improved selection of patients for surgery.

Factors influencing clinicians' perceptions of interruptions as disturbing or non-disturbing : a qualitative study
- 2016
-
In: International Emergency Nursing. - : Elsevier. - 1755-599X .- 1878-013X. ; 27, s. 11-16

Journal article (peer-reviewed)abstract
- OBJECTIVE: Emergency departments consist of multiple systems requiring interaction with one another while still being able to operate independently, creating frequent interruptions in the clinical workflow. Most research on interruptions in health care settings has focused on the relationship between interruptions and negative outcomes. However, there are indications that not all interruptions are negatively perceived by those being interrupted. Therefore, this study aimed to explore factors that influence when a clinician perceives interruptions as non-disturbing or disturbing in an emergency department context.METHOD: Explorative design based on interviews with 10 physicians and 10 registered nurses at two Swedish emergency departments. Data were analyzed using qualitative content analysis.RESULT: Factors influencing whether emergency department clinicians perceived interruptions as non-disturbing or disturbing were identified: clinician's constitution, external factors of influence and the nature of the interrupted task. The clinicians' perceptions were related to a complex of attributes inherent in these three factors at the time of the interruption. Thus, the same type of interruption could be perceived as either non-disturbing or disturbing contingent on the surrounding circumstances in which the event occurred.CONCLUSION: Emergency department clinicians' perceptions of interruptions as non-disturbing or disturbing were related to the character of identified influencing factors.

Reasons for interrupting colleagues during emergency department work : A qualitative study
- 2016
-
In: International Emergency Nursing. - : Elsevier. - 1755-599X .- 1878-013X. ; 29, s. 21-26
-
Journal article (peer-reviewed)abstract
- Objective: Emergency department team members frequently need to interact with each other, a circumstance causing multiple interruptions. However, information is lacking about the motives underlying these interruptions and this study aimed to explore clinicians' reasons to interrupt colleagues during emergency department work.Method: Semi-structured interviews with 10 physicians and 10 registered nurses at two Swedish emergency departments. The interviews were analyzed inductively using content analysis.Results: The working conditions to some extent sustained the clinicians' need to interrupt, for example different routines. Another reason to interrupt was to improve the initiator's work process, such as when the initiators perceived that the interruption had high clinical relevance. The third reason concerns the desire to influence the work process of colleagues in order to prevent mistakes and provide information for the person being interrupted to improve patient care.Conclusion: The three identified categories for why emergency department clinicians interrupt their colleagues were related to working conditions and a wish to improve/influence the work processes for both initiators and recipients. Several of the reasons given for interrupting colleagues were done in order to improve patient care. Interruptions perceived as negative to the recipient were mostly related to the working conditions.

A smartphone application for dispatch of lay responders to out-of-hospital cardiac arrests.
- 2018
-
In: Resuscitation. - : Elsevier BV. - 1873-1570 .- 0300-9572. ; 126, s. 160-165
-
Journal article (peer-reviewed)abstract
- Dispatch of lay volunteers trained in cardiopulmonary resuscitation (CPR) and equipped with automated external defibrillators (AEDs) may improve survival in cases of out-of-hospital cardiac arrest (OHCA). The aim of this study was to investigate the functionality and performance of a smartphone application for locating and alerting nearby trained laymen/women in cases of OHCA.A system using a smartphone application activated by Emergency Dispatch Centres was used to locate and alert laymen/women to nearby suspected OHCAs. Lay responders were instructed either to perform CPR or collect a nearby AED. An online survey was carried out among the responders.From February to August 2016, the system was activated in 685 cases of suspected OHCA. Among these, 224 cases were Emergency Medical Services (EMSs)-treated OHCAs (33%). EMS-witnessed cases (n=11) and cases with missing survey data (n=15) were excluded. In the remaining 198 OHCAs, lay responders arrived at the scene in 116 cases (58%), and prior to EMSs in 51 cases (26%). An AED was attached in 17 cases (9%) and 4 (2%) were defibrillated. Lay responders performed CPR in 54 cases (27%). Median distance to the OHCA was 560m (IQR 332-860m), and 1280m (IQR 748-1776m) via AED pick-up. The survey-answering rate was 82%.A smartphone application can be used to alert CPR-trained lay volunteers to OHCAs for CPR. Further improvements are needed to shorten the time to defibrillation before EMS arrival.

Non-specific complaints in the ambulance; predisposing structural factors
- 2015
-
In: BMC Emergency Medicine. - : BioMed Central. - 1471-227X. ; 15
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The pre-hospital assessment non-specific complaint (NSC) often applies to patients whose diagnosis does not match any other specific assessment correlating to particular symptoms or diseases, though some previous studies have found them to be related to serious underlying conditions. The aim was to identify whether the structural factors such as urgency according to the dispatch priority of the Emergency Medical Communication Centre (EMCC) or work load in the Emergency Medical Services (EMS) are predisposing factors for the assessment of NSC instead of a specific assessment.METHODS: All patients with assessed condition NSCs by the EMS to Södersjukhuset during 2011 (n = 493) were compared with gender- and age-matched controls (n = 493), which were randomly drawn from all patients with specific conditions in the EMS, regarding day of week, time of day and priority set by EMCC with chi-squared tests and multivariate logistic regression models.RESULTS: Among patients with NSCs, more were females (58 %) and the median age was 82. Almost all patients were categorized with NSCs during the daytime (8 a.m. to 9 p.m.), i.e. 450 (91 %) as compared to 373 (75 %) of those with specific conditions (p < 0.01). The risk of having an EMS dispatched as low priority by the EMCC was almost doubled among patients with NSCs compared to controls (OR 1.97, 95 % CI 1.38-2.79).CONCLUSIONS: Since patients with NSCs appear most frequently during the hours with most transportations for the EMS, i.e. 10 a.m. to 2 p.m., and the risk of having the assessment NSC was doubled if the EMCC dispatched EMS as low priority, structural factors might be predisposing factors for the assessment.

Medical versus non medical etiology in out-of-hospital cardiac arrest-Changes in outcome in relation to the revised Utstein template.
- 2016
-
In: Resuscitation. - : Elsevier. - 0300-9572 .- 1873-1570. ; 110, s. 48-55
-
Journal article (peer-reviewed)abstract
- INTRODUCTION:The Utstein-style recommendations for reporting etiology and outcome in out-of-hospital cardiac arrest (OHCA) from 2004 have recently been revised. Among other etiologies a medical category is now introduced, replacing the cardiac category from Utstein template 2004.AIM:The aim of this study is to describe characteristics and temporal trends from reporting OHCA etiology according to the revised Utstein template 2014 in regards to patient characteristics and 30-day survival rates.METHODS:This registry study is based on consecutive OHCA cases reported from the Emergency medical services (EMS) to the Swedish Registry of Cardiopulmonary Resuscitation (SRCR) 1992-2014. Characteristics, including a presumed cardiac etiology in Utstein template 2004, were transcribed to a medical etiology in Utstein template 2014.RESULTS:Of a total of n=70,846 cases, 92% were categorized as having a medical etiology and 8% as having a non-medical cause. Using the new classifications, the 30-day survival rate has significantly increased over a 20-year period from 4.7% to 11.0% in the medical group and from 3% to 9.9% in the non-medical group (p≤0.001). Trauma was the most common cause in OHCA of a non-medical etiology (26%) with a 30-day survival rate of 3.4% whilst drowning and drug overdose had the highest survival rates (14% and 10% respectively).CONCLUSION:Based on Utstein 2014 categories of etiology, overall survival after OHCA with a medical etiology has more than doubled in a 20-year period and tripled for non-medical cases. Patients with a medical etiology found in a shockable rhythm have the highest chance of survival. There is great variability in characteristics among non-medical cases.

Factors predictive of hospital admission for children via emergency departments in Australia and Sweden: an observational cross-sectional study
- 2024
-
In: BMC Health Services Research. - : Springer Nature. - 1472-6963. ; 24:1
-
Journal article (peer-reviewed)abstract
- Background: Identifying factors predictive of hospital admission can be useful to prospectively inform bed management and patient flow strategies and decrease emergency department (ED) crowding. It is largely unknown if admission rate or factors predictive of admission vary based on the population to which the ED served (i.e., children only, or both adults and children). This study aimed to describe the profile and identify factors predictive of hospital admission for children who presented to four EDs in Australia and one ED in Sweden.Methods: A multi-site observational cross-sectional study using routinely collected data pertaining to ED presentations made by children < 18 years of age between July 1, 2011 and October 31, 2012. Univariate and multivariate analysis were undertaken to determine factors predictive of hospital admission.Results: Of the 151,647 ED presentations made during the study period, 22% resulted in hospital admission. Admission rate varied by site; the children's EDs in Australia had higher admission rates (South Australia: 26%, Queensland: 23%) than the mixed (adult and children's) EDs (South Australia: 13%, Queensland: 17%, Sweden: 18%). Factors most predictive of hospital admission for children, after controlling for triage category, included hospital type (children's only) adjusted odds ratio (aOR):2.3 (95%CI: 2.2-2.4), arrival by ambulance aOR:2.8 (95%CI: 2.7-2.9), referral from primary health aOR:1.5 (95%CI: 1.4-1.6) and presentation with a respiratory or gastrointestinal condition (aOR:2.6, 95%CI: 2.5-2.8 and aOR:1.5, 95%CI: 1.4-1.6, respectively). Predictors were similar when each site was considered separately.Conclusions: Although the characteristics of children varied by site, factors predictive of hospital admission were mostly similar. The awareness of these factors predicting the need for hospital admission can support the development of clinical pathways.

Decreased general condition in the emergency department : high in-hospital mortality and a broad range of discharge diagnoses
- 2015
-
In: European journal of emergency medicine. - : Lippincott Williams & Wilkins. - 0969-9546 .- 1473-5695. ; 22:4, s. 241-246
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Decreased general condition (DGC) is a frequent presenting complaint within the Adaptive Triage Process. DGC describes a nonspecific decline in health and well-being, and it is common among elderly patients in the emergency department (ED).AIM: The aim of this study was to compare the in-hospital mortality among patients presenting with DGC with that among patients in the corresponding triage category presenting with other complaints to an ED. The secondary aim was to describe the discharge diagnoses of patients presenting with DGC.METHODS: All patients admitted to Södersjukhuset from the ED in 2008 were included. The difference in the in-hospital mortality rate was stratified for triage category at the ED, between patients with DGC (n=1182) and those with all other presenting complaints (n=20 775), and assessed with sex-adjusted and age-adjusted logistic regression models. Discharge diagnoses were assessed as the primary discharge diagnosis according to International Statistical Classification of Diseases and Related Health Problems 10th revision (ICD-10) in the medical discharge notes.RESULTS: A total of 1182 patients with DGC at the ED were admitted for in-hospital care, and they had a four-fold risk of suffering an in-hospital death [odds ratio 4.74 (95% confidence interval 3.88-5.78)] compared with patients presenting with other presenting complaints. The most common discharge diagnoses were diseases of the circulatory system (14%), respiratory system (14%), and genitourinary system (10%).INTERPRETATION: Patients presenting with DGC to an ED often receive low triage priority, frequently require admission for in-hospital care, and, because of the three-fold increased risk of in-hospital death compared with others, belong to a high-risk group.

Health-related quality of life after oesophageal cancer surgery for prediction of morbidity and mortality
- 2010
-
Doctoral thesis (other academic/artistic)abstract
- This thesis investigates the health-related quality of life (HRQL) among surgically treated oesophageal cancer patients. The established curative treatment for oesophageal cancer is extensive surgery with a high risk of morbidity and a limited chance of long-term survival. Only every third patient is suitable for surgery. Subjective outcomes such as HRQL are therefore of particular importance among this group of patients. In three of the four studies (I, II, IV) included in this thesis, a nationwide Swedish cohort of oesophageal cancer patients, operated in 2001-2005, was used, while in study III a British cohort of operated patients was used. In all studies, HRQL was assessed with an international validated core questionnaire on the symptoms and functions of cancer (EORTC QLQ-C30). Studies I, II and IV also included an oesophageal cancer specific module (EORTC QLQ-OES18). In Studies I and III a difference in transformed mean scores of at least 10 points on a scale of 0-100 was used as a cut-off for clinical relevance. In Studies II and IV raw scores were categorised into good or poor HRQL. In Study I, the long term HRQL after oesophageal cancer surgery was investigated. HRQL was shown to be similar both six months and three years postoperatively, which suggests that the long-standing HRQL level is already established at six months. The HRQL was poorer than that of the general population. Study II assessed if patient and tumour characteristics affect HRQL six months postoperatively. Sex, age and BMI showed no associations while co-morbidity and tumour characteristics such as histology and tumour stage affected HRQL. The findings may be useful for clinical decision making. Study III explored if both baseline HRQL and changes in HRQL from baseline to six months followup was associated with survival. Dyspnoea at baseline was associated with an increased risk of mortality. Not recovering physical function and worsening of pain and fatigue were linked with a higher risk of mortality. Therefore, changes in HRQL might be prognostic and of importance when planning follow-up and supportive care. Study IV analysed whether postoperative HRQL was associated with survival. Poor HRQL measures were associated with increased risk of mortality. This knowledge could be used for prognostic discussions and intensity of the clinical follow-up. In conclusion, this thesis shows that measures of HRQL could aid decision-making prior to treatment and in planning the follow-up of osesophageal cancer patients.

Health-related quality of life after surviving an out-of-hospital compared to an in-hospital cardiac arrest : a Swedish population-based registry study
- 2020
-
In: Resuscitation. - : Elsevier. - 0300-9572 .- 1873-1570. ; 151, s. 77-84

Journal article (peer-reviewed)abstract
- BackgroundHealth-related quality of life (HRQoL) has been reported for out-hospital (OHCA) and in-hospital cardiac arrest (IHCA) separately, but potential differences between the two groups are unknown. The aim of this study is therefore to describe and compare HRQoL in patients surviving OHCA and IHCA.MethodsPatients ≥18 years with Cerebral Performance Category 1–3 included in the Swedish Registry for Cardiopulmonary Resuscitation between 2014 and 2017 were included. A telephone interview was performed based on a questionnaire sent 3–6 months post cardiac arrest, including EQ-5D-5L and the Hospital Anxiety and Depression Scale. Mann–Whitney U test and multiple linear- and ordinal logistic regression analyses were used to describe and compare HRQoL in OHCA and IHCA survivors. Adjustments were made for sex, age and initial rhythm.ResultsIn all, 1369 IHCA and 772 OHCA survivors were included. Most OHCA and IHCA survivors reported no symptoms of with anxiety (88% and 84%) or depression (87% and 85%). IHCA survivors reported significantly more problems in the health domains mobility, self-care, usual activities and pain/discomfort (p < 0.001 for all) and scored lower general health measured by EQ-VAS (median 70 vs. 80 respectively, p < 0.001) compared with the OHCA survivors.ConclusionSurvivors of IHCA reported significantly worse HRQoL compared to survivors of OHCA. Consequently, research data gathered from one of these populations may not be generalizable to the other.

Nonspecific abdominal pain in the Emergency Department : malignancy incidence in a nationwide Swedish cohort study
- 2018
-
In: European journal of emergency medicine. - : Copyright Wolters Kluwer Health, Inc. All rights reserved. - 0969-9546 .- 1473-5695. ; 25:2, s. 105-109

Journal article (peer-reviewed)abstract
- INTRODUCTIONThe role of emergency physicians is to identify patients in need of immediate treatment, but also to identify symptoms indicative of serious, if not immediately life-threatening conditions. AIMTo assess whether symptoms described as nonspecific abdominal pain (NSAP) could be the first indication of an abdominal malignancy. MATERIALS AND METHODSThis was a nationwide registry-based cohort study of all patients discharged with NSAP from Swedish Emergency Departments (EDs) during the year 2011, based on Swedish patient registries of inpatient and outpatient care, and the cause of death registry, studying patients diagnosed with de novo cancer within a year after their NSAP discharge. RESULTSOf 24 801 patients discharged with NSAP in 2011, 2.2% were assigned a cancer diagnosis within 12 months. Almost 20% of patients diagnosed with a malignancy died within the year, and 16% of these deaths occurred within a month after the ED visit. The majority of patients with cancer were 60 years of age or older, and thus significantly older than the remaining NSAP patients. Patients with malignancies also had a greater number of comorbidities than the remaining NSAP patients (P<0.01). CONCLUSIONA small percentage of patients discharged with NSAP from Swedish EDs are diagnosed with a malignancy within a year. Patients aged 60 years or older and with comorbidities were over-represented in terms of developing malignancies after discharge. Emergency physicians should be aware of the fact that diffuse abdominal symptoms in elderly patients could be the first sign of an underlying malignancy and more liberally refer such patients for follow-up in primary care.

Pain rating in the ED—a comparison between 2 scales in a Swedish hospital
- 2015
-
In: American Journal of Emergency Medicine. - : Elsevier Inc. - 0735-6757 .- 1532-8171. ; 33:3, s. 419-422
-
Journal article (peer-reviewed)abstract
- Abstract Background Pain is common at an emergency department (ED). Two common scales used to rate intensity are the visual analog scale (VAS) and the numeric rating scale (NRS), but it remains unknown which is superior to use in the ED. Aim The aim of the study is to compare correlations between values on the VAS and the NRS in patients visiting the ED as well as to assess the patients' preference of scale. Methods Patients who visited the ED due to chest pain, abdominal pain, or an orthopedic condition during autumn 2012 were enrolled onto a cross-sectional study with a consecutive sample. Patients rated their pain using the VAS and NRS scales. They answered an open-ended oral questionnaire regarding their preference and their estimation of the sufficiency of the scales. Data were analyzed with significance test. Results In all, 217 patients (70% of eligible, 94% of invited) participated. The pain scores generated from the NRS and the VAS were found to strongly correlate (mean difference, 0.41; 95% confidence interval, 0.29-0.53). Most patients found the NRS easier to use than the VAS (61% and 22%, respectively; P < .001). Furthermore, a majority reported that the NRS reflected/described their pain better than the VAS (53% and 26%, respectively; P < .01). Conclusion Because values on the NRS correspond well to values on the VAS, values rated with different scales over time might be comparable. Because a majority of the patients found the NRS scale simpler to use and preferred it over the VAS, it might be more appropriate to use in the ED.

Factors of importance to 30-day survival after in-hospital cardiac arrest in Sweden - A population-based register study of more than 18,000 cases.
- 2017
-
In: International Journal of Cardiology. - : Elsevier BV. - 0167-5273 .- 1874-1754.
-
Journal article (peer-reviewed)abstract
- BACKGROUND AND OBJECTIVE: In-hospital cardiac arrest (IHCA) constitutes a major contributor to cardiovascular mortality. The aim of the present study was to investigate factors of importance to 30-day survival after IHCA in Sweden.METHODS: A retrospective register study based on the Swedish Register of Cardiopulmonary Resuscitation (SRCPR) 2006-2015. Sixty-six of 73 hospitals in Sweden participated. The inclusion criterion was a confirmed cardiac arrest in which resuscitation was attempted among patients aged >18years.RESULTS: In all, 18,069 patients were included, 39% of whom were women. The median age was 75years. Thirty-day survival was 28.3%, 93% with a CPC score of 1-2. One-year survival was 25.0%. Overall IHCA incidence in Sweden was 1.7 per 1000 hospital admissions. Several factors were found to be associated with 30-day survival in a multivariable analysis. They included cardiac arrest (CA) at working days during the daytime (08-20) compared with weekends and night-time (20-08) (OR 1.51 95% CI 1.39-1.64), monitored CA (OR 2.18 95% CI 1.99-2.38), witnessed CA (OR 2.87 95% CI 2.48-3.32) and if the first recorded rhythm was ventricular fibrillation/tachycardia, especially in combination with myocardial ischemia/infarction as the assumed aetiology of the CA (OR for interaction 4.40 95% CI 3.54-5.46).CONCLUSION: 30-day survival after IHCA is associated with the time of the event, the aetiology of the CA and the degree of monitoring and this should influence decisions regarding the appropriate level of monitoring and care.

Poorer survival after out-of-hospital cardiac arrest among cancer patients : a population-based register study
- 2023
-
In: European Heart Journal: Acute Cardiovascular Care. - 2048-8726 .- 2048-8734. ; 12:8, s. 495-503
-
Journal article (peer-reviewed)abstract
- Aims: The association between cancer and survival after out-of-hospital cardiac arrest (OHCA) has not been thoroughly investigated. We aimed to address this knowledge gap using national, population-based registries. Methods and results: For this study, 30 163 patients with OHCA (≥18 years) were included from the Swedish Register of Cardiopulmonary Resuscitation. Through linkage to the National Patient Registry, 2894 patients (10%) with cancer diagnosed within 5 years prior to OHCA were identified. Differences in 30-day survival between patients with cancer and controls (defined as patients with OHCA without previous cancer diagnosis) were assessed related to cancer stage (locoregional vs. metastasized cancer) and cancer site (e.g. lung cancer, breast cancer, etc.) using logistic regression adjusted for prognostic factors. Long-term survival was presented as a Kaplan-Meier curve. For locoregional cancer, no statistically significant difference in return of spontaneous circulation (ROSC) was seen compared with controls, and metastasized disease was associated with a poorer chance of ROSC. Cancer was associated with a lower 30-day survival for all cancers [adjusted odds ratio (OR) 0.57, confidence interval (CI) 0.49-0.66], locoregional cancer (adjusted OR 0.68, CI 0.57-0.82), and metastasized cancer (adjusted OR 0.24, CI 0.14-0.40) compared with controls. A lower 30-day survival compared with controls was seen for lung, gynaecological and haematological cancers. Conclusion: Cancer is associated with poorer 30-day survival after OHCA. This study suggests that cancer site and disease stage are more relevant factors than cancer in general with regard to its effect on survival after OHCA.

Journal article (peer-reviewed)abstract
- AIM: To describe health status and psychological distress among in-hospital cardiac arrest (IHCA) survivors in relation to gender.METHODS: This national register study consists of data from follow-up registration of IHCA survivors 3-6 months post cardiac arrest (CA) in Sweden. A questionnaire was sent to the survivors, including measurements of health status (EQ-5D-5L) and psychological distress (HADS).RESULTS: Between 2013 and 2015, 594 IHCA survivors were included in the study. The median values for EQ-5D-5L index and EQ VAS among survivors were 0.78 (q1-q3=0.67-0.86) and 70 (q1-q3=50-80) respectively. The values were significantly lower (p<0.001) in women compared to men. In addition, women reported more problems than men in all dimensions of EQ-5D-5L, except self-care. A majority of the respondents reported no problems with anxiety (85.4%) and/or symptoms of depression (87.0%). Women reported significantly more problems with anxiety (p<0.001) and symptoms of depression (p<0.001) compared to men. Gender was significantly associated with poorer health status and more psychological distress. No interaction effects for gender and age were found.CONCLUSIONS: Although the majority of survivors reported acceptable health status and no psychological distress, a substantial proportion reported severe problems. Women reported worse health status and more psychological distress compared to men. Therefore, a higher proportion of women may be in need of support. Health care professionals should make efforts to identify health problems among survivors and offer individualised support when needed.

Soluble urokinase plasminogen activator receptor and lactate as prognostic biomarkers in patients presenting with non-specific chief complaints in the pre-hospital setting - the PRIUS-study
- 2021
-
In: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine. - : BioMed Central. - 1757-7241. ; 29:1
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Emergency Medical Services (EMS) are faced daily with patients presenting with non-specific chief complaints (NSC). Patients presenting with NSCs often have normal vital signs. It has previously been established that NSCs may have a serious underlying condition that has yet to be identified. The aim of the current study was to determine if soluble urokinase plasminogen activator receptor (suPAR) and lactate could be used to identify serious conditions among patients presenting with NSCs to the EMS. The secondary aim was to describe the prognostic value for mortality in the group.METHOD: A blinded prospective observational cohort study was conducted of patients brought to the ED by ambulance after calling the national emergency number 112 and who were assessed as having NSC by the EMS. Biomarkers were measured during index EMS assessment before transportation to the ED. Patients were followed via EMS and hospital electronic health records. Descriptive and logistic regression analyses were used.RESULTS: A total of 414 patients were included, with a median age of 82 years. A serious condition was present in 15.2% of the patients. Elevated suPAR above 3 ng/ml had a positive likelihood ratio (LR+) of 1.17 and a positive predictive value (PPV) of 17.3% as being predictive of a prevalent serious condition. Elevated suPAR above 9 ng/ml had LR+ 4.67 and a PPV of 16.7% as being predictive of 30-day mortality. Lactate was not significantly predictive.CONCLUSION: Pre-hospital suPAR and lactate cannot differentiate serious conditions in need of urgent treatment and assessment in the ED among patients presenting with non-specific chief complaints. suPAR has shown to be predictive of 30-day mortality, which could add some value to the clinical assessment.TRIAL REGISTRATION: NCT03089359.

Non-conveyance in the ambulance service : a population-based cohort study in Stockholm, Sweden
- 2020
-
In: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 10:7
-
Journal article (peer-reviewed)abstract
- OBJECTIVES: Non-conveyed patients represent a significant proportion of all patients cared for by ambulance services in the western world. However, scientific knowledge on non-conveyance is sparse. Therefore, the aim of this study was to describe the prevalence of non-conveyance, investigate associations and compare patients' characteristics, drug administration, initial problems and vital signs between non-conveyed and conveyed patients.DESIGN: A population-based retrospective cohort study.SETTING: The study setting area, Stockholm, Sweden, has a population of 2.3 million inhabitants, with seven emergency hospitals. Annually, approximately 210 000 assignments are performed by 73 ambulances. All ambulance assignments performed from 1 January to 31 December 2015 were included.RESULTS: In total, 23 603 ambulance assignments ended in non-conveyance-13.8% of all ambulance assignments performed in 2015. Compared with conveyed patients, non-conveyed patients were younger and more often female (median age 50.1 years for non-conveyed vs 61.7 years for conveyed; female=52 %, both p values <0.001). Approximately half of all ambulance assignments ending in non-conveyance were initially prioritised and dispatched as the highest priority. Non-conveyed patients were more often assessed by ambulance clinicians as presenting non-specific symptoms or symptoms related to psychiatric problems. Low blood glucose levels were highly associated with non-conveyance (adjusted OR (AOR): 15; 95 % CI 11.18 to 20.13), although non-conveyed patients presented abnormal vital signs across all categories of vital signs. Moreover, drugs were more often administered to younger non-conveyed patients. Older patients were more often conveyed and administered drugs once conveyed (AOR: 1.29; 95 % CI 1.07 to 1.56).CONCLUSIONS: This study shows that non-conveyed patients represent a non-negligible proportion of all patients in contact with ambulance services. In general, most cases of non-conveyance occur at the highest dispatch level, to a large extent involve younger patients, and features problems assessed by ambulance clinicians as non-specific or related to psychiatric symptoms.

Non-conveyance of older adult patients and association with subsequent clinical and adverse events after initial assessment by ambulance clinicians : a cohort analysis
- 2021
-
In: BMC Emergency Medicine. - : BioMed Central. - 1471-227X. ; 21:1
-
Journal article (peer-reviewed)abstract
- BackgroundOlder adults (age >= 65 years) represent a significant proportion of all patients who are not transported to hospital after assessment by ambulance clinicians (non-conveyed patients). This study aimed to fill the knowledge gap in the understanding of the prevalence of older adult non-conveyed patients and investigate their characteristics and risk factors for subsequent and adverse events with those of younger non-conveyed patients comparatively.MethodsThis population-based retrospective cohort study included all adult non-conveyed patients who availed the ambulance service of Region Stockholm, Sweden in 2015; they were age-stratified into two groups: 18-64 and >= 65 years. Inter-group differences in short-term outcomes (i.e. emergency department visits, hospitalisations, and mortality within 7 days following non-conveyance) were assessed using multivariate regression analyses.ResultsOlder adult patients comprised 48% of the 17,809 non-conveyed patients. Dispatch priority levels were generally lower among older non-conveyed patients than among younger patients. Non-conveyance among older patients occurred more often during daytime, and they were more frequently assessed by ambulance clinicians with nonspecific presenting symptoms. Approximately one in five older adults was hospitalised within 7 days following non-conveyance. Patients presenting with infectious symptoms had the highest mortality risk following non-conveyance. Oxygen saturation level < 95% or systolic blood pressure > 160 mmHg had significantly higher associations with hospitalisation within 7 days following non-conveyance in older adult patients.ConclusionsOlder adult patients have an increased risk for adverse events following non-conveyance. In combination with a complex and variating presentation of symptoms and vital signs proved difficult for dispatch operators and ambulance clinicians to identify and assess, the identified risks raise questions on the patient safety of older adult non-conveyed patients. The results indicate a system failure that need to be managed within the ambulance service organisation to achieve higher levels of patient safety for older non-conveyed patients.

Drug therapy in cardiac arrest : a review of the literature
- 2016
-
In: European heart journal. Cardiovascular pharmacotherapy. - : Oxford University Press (OUP). - 2055-6845 .- 2055-6837. ; 2:1, s. 54-75

Journal article (peer-reviewed)abstract
- The aim of this study was to review the literature on human studies of drug therapy in cardiac arrest during the last 25 years. In May 2015, a systematic literature search was performed in PubMed, Embase, the Cochrane Library, and CRD databases. Prospective interventional and observational studies evaluating a specified drug therapy in human cardiac arrest reporting a clinical endpoint [i.e. return of spontaneous circulation (ROSC) or survival] and published in English 1990 or later were included, whereas animal studies, case series and reports, studies of drug administration, drug pharmacology, non-specified drug therapies, preventive drug therapy, drug administration after ROSC, studies with primarily physiological endpoints, and studies of traumatic cardiac arrest were excluded. The literature search identified a total of 8936 articles. Eighty-eight articles met our inclusion criteria and were included in the review. We identified no human study in which drug therapy, compared with placebo, improved long-term survival. Regarding adrenaline and amiodarone, the drugs currently recommended in cardiac arrest, two prospective randomized placebo-controlled trials, were identified for adrenaline, and one for amiodarone, but they were all underpowered to detect differences in survival to hospital discharge. Of all reviewed studies, only one recent prospective study demonstrated improved neurological outcome with one therapy over another using a combination of vasopressin, steroids, and adrenaline as the intervention compared with standard adrenaline administration. The evidence base for drug therapy in cardiac arrest is scarce. However, many human studies on drug therapy in cardiac arrest have not been powered to identify differences in important clinical outcomes such as survival to hospital discharge and favourable neurological outcome. Efforts are needed to initiate large multicentre prospective randomized clinical trials to evaluate both currently recommended and future drug therapies.

Underlying reasons for sex difference in survival following out-of-hospital cardiac arrest: a mediation analysis
- 2024
-
In: Europace. - 1099-5129 .- 1532-2092. ; 26:5
-
Journal article (peer-reviewed)abstract
- AimsPrevious studies have indicated a poorer survival among women following out-of-hospital cardiac arrest (OHCA), but the mechanisms explaining this difference remain largely uncertain.This study aimed to assess the survival after OHCA among women and men and explore the role of potential mediators, such as resuscitation characteristics, prior comorbidity, and socioeconomic factors.Methods and resultsThis was a population-based cohort study including emergency medical service-treated OHCA reported to the Swedish Registry for Cardiopulmonary Resuscitation in 2010–2020, linked to nationwide Swedish healthcare registries. The relative risks (RR) of 30-day survival were compared among women and men, and a mediation analysis was performed to investigate the importance of potential mediators. Total of 43 226 OHCAs were included, of which 14 249 (33.0%) were women. Women were older and had a lower proportion of shockable initial rhythm. The crude 30-day survival among women was 6.2% compared to 10.7% for men [RR 0.58, 95% confidence interval (CI) = 0.54–0.62]. Stepwise adjustment for shockable initial rhythm attenuated the association to RR 0.85 (95% CI = 0.79–0.91). Further adjustments for age and resuscitation factors attenuated the survival difference to null (RR 0.98; 95% CI = 0.92–1.05). Mediation analysis showed that shockable initial rhythm explained ∼50% of the negative association of female sex on survival. Older age and lower disposable income were the second and third most important variables, respectively.ConclusionWomen have a lower crude 30-day survival following OHCA compared to men. The poor prognosis is largely explained by a lower proportion of shockable initial rhythm, older age at presentation, and lower income.

Outcomes in Patients With Chest Pain Discharged After Evaluation Using a High-Sensitivity Troponin T Assay
- 2017
-
In: Journal of the American College of Cardiology. - : Elsevier BV. - 0735-1097 .- 1558-3597. ; 69:21, s. 2622-2630
-
Journal article (peer-reviewed)abstract
- BACKGROUND Most patients with chest pain are discharged from the emergency department (ED) with the diagnosis "unspecified chest pain." It is unknown if evaluation with a high-sensitivity troponin T (hsTnT) assay affects prognosis in this large population.OBJECTIVES The aim was to investigate whether the introduction of an hsTnT assay is associated with reduced incidence of major adverse cardiac events (MACEs) and cardiovascular (CV) risk profile in patients with chest pain discharged from the ED.METHODS The study included 65,696 patients with "unspecified chest pain" discharged from 16 Swedish hospital EDs between 2006 and 2013 in which an hsTnT assay was introduced as the clinical routine. Patients evaluated with a conventional and an hsTnT assay were compared regarding the occurrence of 30-day MACE and CV risk profile based on information from national registries. Patients directly discharged and those discharged after an initial admission were analyzed separately.RESULTS Fewer directly discharged patients experienced a MACE when evaluated with an hsTnT compared with a conventional assay (0.6% vs. 0.9%; odds ratio [OR]: 0.7; 95% confidence interval [CI]: 0.57 to 0.83). In contrast, more patients discharged after an initial admission experienced a MACE when evaluated with an hsTnT (7.2% vs. 3.4%; OR: 2.18; 95% CI: 1.76 to 2.72). Admitted patients had a higher general CV risk profile when evaluated with hsTnT, whereas directly discharged patients had a lower general CV risk profile with the same test.CONCLUSIONS Patients directly discharged from the ED with unspecified chest pain experienced fewer MACEs and had a better risk profile when evaluated with hsTnT. Our findings suggest that more true at-risk patients were identified and admitted. The implementation of hsTnT assays in Swedish hospitals has improved evaluations in the ED.

Low adherence to legislation regarding Do-Not-Attempt-Cardiopulmonary-Resuscitation orders in a Swedish University Hospital
- 2021
-
In: Resuscitation Plus. - : Elsevier BV. - 2666-5204. ; 6
-
Journal article (peer-reviewed)abstract
- Background The ethical principles of resuscitation have been incorporated into Swedish legislation so that a decision to not attempt cardiopulmonary resuscitation (DNACPR) entails (1) consultation with patient or relatives if consultation with patient was not possible and documentation of their attitudes; (2) consultation with other licensed caregivers; (3) documentation of the grounds for the DNACPR. Our aim was to evaluate adherence to this legislation, explore the grounds for the decision and the attitudes of patients and relatives towards DNACPR orders. Methods We included DNACPR forms issued after admission through the emergency department at Karolinska University Hospital between 1st January and 31st October, 2015. Quantitative analysis evaluated adherence to legislation and qualitative analysis of a random sample of 20% evaluated the grounds for the decision and the attitudes. Results The cohort consisted of 3583 DNACPR forms. In 40% of these it was impossible to consult the patient, and relatives were consulted in 46% of these cases. For competent patients, consultation occurred in 28% and the most common attitude was to wish to refrain from resuscitation. Relatives were consulted in 26% and they mainly agreed with the decision. Grounds for the DNAR decision was most commonly severe chronic comorbidity, malignancy or multimorbidity with or without an acute condition. All requirements of the legislation were fulfilled in 10% of the cases. Conclusion In 90% of the cases physicians failed to fulfil all requirements in the Swedish legislation regarding DNAR orders. The decision was mostly based on chronic, severe comorbidity or multimorbidity.

Prearrest prediction of favourable neurological survival following in-hospital cardiac arrest : The Prediction of outcome for In-Hospital Cardiac Arrest (PIHCA) score.
- 2019
-
In: Resuscitation. - : Elsevier BV. - 0300-9572 .- 1873-1570. ; 143, s. 92-99

Journal article (peer-reviewed)abstract
- BACKGROUND: A prearrest prediction tool can aid clinicians in consolidating objective findings with clinical judgement and in balance with the values of the patient be a part of the decision process for do-not-attempt-resuscitation (DNAR) orders. A previous prearrest prediction tool for in-hospital cardiac arrest (IHCA) have not performed satisfactory in external validation in a Swedish cohort. Therefore our aim was to develop a prediction model for the Swedish setting.METHODS: Model development was based on previous external validation of The Good Outcome Following Attempted Resuscitation (GO-FAR) score, with 717 adult IHCAs. It included redefinition and reduction of predictors, and addition of chronic comorbidity, to create a full model of 9 predictors. Outcome was favourable neurological survival defined as Cerebral Performance Category score 1-2 at discharge. The likelihood of favourable neurological survival was categorised into very low (<1%), low (1-3%) and above low (>3%).RESULTS: We called the model the Prediction of outcome for In-Hospital Cardiac Arrest (PIHCA) score. The AUROC was 0.808 (95% CI 0.807-0.810) and calibration was satisfactory. With a cutoff of 3% likelihood of favourable neurological survival sensitivity was 99.4% and specificity 8.4%. Although specificity was limited, predictive value for classification into ≤3% likelihood of favorable neurological survival was high (97.4%) and false classification into ≤3% likelihood of favourable neurological survival was low (0.6%).CONCLUSION: The PIHCA score has the potential to be used as an objective tool in prearrest prediction of outcome after IHCA, as part of the decision process for a DNAR order.

Journal article (peer-reviewed)abstract
- BACKGROUND: A do-not-attempt-resuscitation order is issued when it is against the wishes of the patient that cardiopulmonary resuscitation is performed, or when the chance of good quality survival is minimal. Therefore it is essential for physicians to make an objective prearrest prediction of the outcome after an in-hospital cardiac arrest (IHCA). Our aim was external validation of the Good Outcome Following Attempted Resuscitation (GO-FAR) score in a population based setting.METHODS: The study was based on a retrospective cohort of adult IHCAs in Stockholm County 2013-2014 identified through the Swedish Cardiopulmonary Resuscitation Registry. This registry provided patient and event characteristics and neurological outcome at discharge. Neurologically intact survival is defined as Cerebral Performance Category score (CPC) 1 at discharge. Data for the GO-FAR variables was obtained from manual review of electronic patient records. Model performance was evaluated by measure of discrimination with the area under the receiver operating curve (AUROC) and calibration with assessment of the calibration plot.RESULTS: The cohort included 717 patients with neurologically intact survival at discharge of 22%. In complete case analysis (523 cases) AUROC was 0.82 (95% CI 0.78-0.86) indicating good discrimination. The calibration plot showed that the GO-FAR score systematically underestimates the probability of neurologically intact survival.CONCLUSION: The GO-FAR score has satisfactory discrimination, but assessment of the calibration shows that neurologically intact survival is systematically underestimated. Therefore, only with caution should it without model update be taken into clinical practice in settings similar to ours.

Journal article (peer-reviewed)abstract
- Abstract Background In-hospital cardiac arrest (IHCA) has a poor prognosis and clinicians often write “Do-Not-Attempt-Resuscitation” (DNAR) orders based on co-morbidities. Aim To assess the impact of the Age-combined Charlson Co-morbidity Index (ACCI) on 30-days survival after IHCA. Material and methods All patients suffering IHCA at Karolinska University Hospital between 1st January and 31st December 2014 were included. Data regarding patient characteristics, co-morbidities and survival were drawn from the electronic patient records. Co-morbidities were assessed prior to the IHCA as ICD-10 codes according to the ACCI. Differences in survival were assessed with adjusted logistic regression models and presented as Odds Ratios with 95% Confidence Intervals (OR, 95% CI) between patients with an ACCI of 0–4 points versus those with 5–7 points, as well as those with ≥8 points. Adjustments included hospital site, heart rhythm, ECG surveillance, witnessed status and place of IHCA. Results In all, 174 patients suffered IHCA, of whom 41 (24%) survived at least 30 days. Patients with an ACCI of 5–7 points had a minor chance and those with an ACCI of ≥8 points had a minimal chance of surviving IHCA compared to those with an ACCI of 0–4 points (adjusted OR 0.10, 95% CI 0.04–0.26 and OR 0.04, 95% CI 0.03–0.42, respectively). Conclusion Patients with a moderate or severe burden of ACCI have a minor chance of surviving an IHCA. This information could be used as part of the decision tools during ongoing CPR, and could be an aid for clinicians in planning care and discussing DNAR orders.

Journal article (peer-reviewed)abstract
- AimStrategies to increase provision of bystander CPR include mass education of laypersons. Additionally, programs directed at emergency dispatchers to provide CPR instructions during emergency calls to untrained bystanders have emerged. The aim of this study was to evaluate the association between dispatcher-assisted CPR (DA- CPR) and 30-day survival compared with no CPR or spontaneously initiated CPR by lay bystanders prior to emergency medical services in out of hospital cardiac arrest (OHCA).MethodsNationwide observational cohort study including all consecutive lay bystander witnessed OHCAs reported to the Swedish Register for Cardiopulmonary Resuscitation in 2010–2017. Exposure was categorized as: no CPR (NO-CPR), DA-CPR and spontaneously initiated CPR (SP-CPR) prior to EMS arrival. Propensity-score matched cohorts were used for comparison between groups. Main Outcome was 30-day survival.ResultsA total of 15 471 patients were included and distributed as follows: NO-CPR 6440 (41.6%), DA-CPR 4793 (31.0%) and SP-CPR 4238 (27.4%). Survival rates to 30 days were 7.1%, 13.0% and 18.3%, respectively. In propensity-score matched analysis (DA-CPR as reference), NO-CPR was associated with lower survival (conditional OR 0.61, 95% CI 0.52–0.72) and SP-CPR was associated with higher survival (conditional OR 1.21 (95% CI 1.05–1.39).ConclusionsDA-CPR was associated with a higher survival compared with NO-CPR. However, DA-CPR was associated with a lower survival compared with SP-CPR. These results reinforce the vital role of DA-CPR, although continuous efforts to disseminate CPR training must be considered a top priority if survival after out of hospital cardiac arrest is to continue to increase.

- AIM: To study the characteristics and outcome among cardiac arrest cases with COVID-19 and differences between the pre-pandemic and the pandemic period in out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA).METHOD AND RESULTS: We included all patients reported to the Swedish Registry for Cardiopulmonary Resuscitation from 1 January to 20 July 2020. We defined 16 March 2020 as the start of the pandemic. We assessed overall and 30-day mortality using Cox regression and logistic regression, respectively. We studied 1946 cases of OHCA and 1080 cases of IHCA during the entire period. During the pandemic, 88 (10.0%) of OHCAs and 72 (16.1%) of IHCAs had ongoing COVID-19. With regards to OHCA during the pandemic, the odds ratio for 30-day mortality in COVID-19-positive cases, compared with COVID-19-negative cases, was 3.40 [95% confidence interval (CI) 1.31-11.64]; the corresponding hazard ratio was 1.45 (95% CI 1.13-1.85). Adjusted 30-day survival was 4.7% for patients with COVID-19, 9.8% for patients without COVID-19, and 7.6% in the pre-pandemic period. With regards to IHCA during the pandemic, the odds ratio for COVID-19-positive cases, compared with COVID-19-negative cases, was 2.27 (95% CI 1.27-4.24); the corresponding hazard ratio was 1.48 (95% CI 1.09-2.01). Adjusted 30-day survival was 23.1% in COVID-19-positive cases, 39.5% in patients without COVID-19, and 36.4% in the pre-pandemic period.CONCLUSION: During the pandemic phase, COVID-19 was involved in at least 10% of all OHCAs and 16% of IHCAs, and, among COVID-19 cases, 30-day mortality was increased 3.4-fold in OHCA and 2.3-fold in IHCA.

Rapid response team activation prior to in-hospital cardiac arrest: Areas for improvements based on a national cohort study
- 2023
-
In: Resuscitation. - 0300-9572 .- 1873-1570. ; 193
-
Journal article (peer-reviewed)abstract
- Introduction: Rapid response teams (RRTs) are designed to improve the "chain of prevention" of in-hospital cardiac arrest (IHCA). We studied the 30-day survival of patients reviewed by RRTs within 24 hours prior to IHCA, as compared to patients not reviewed by RRTs.Methods: A nationwide cohort study based on the Swedish Registry of Cardiopulmonary Resuscitation, between January 1st, 2014, and December 31st, 2021. An explorative, hypothesis-generating additional in-depth data collection from medical records was performed in a small subgroup of general ward patients reviewed by RRTs.Results: In all, 12,915 IHCA patients were included. RRT-reviewed patients (n = 2,058) had a lower unadjusted 30-day survival (25% vs 33%, p < 0.001), a propensity score based Odds ratio for 30-day survival of 0.92 (95% Confidence interval 0.90-0.94, p < 0.001) and were more likely to have a respiratory cause of IHCA (22% vs 15%, p < 0.001). In the subgroup (n = 82), respiratory distress was the most common RRT trigger, and 24% of the RRT reviews were delayed. Patient transfer to a higher level of care was associated with a higher 30-day survival rate (20% vs 2%, p < 0.001).Conclusion: IHCA preceded by RRT review is associated with a lower 30-day survival rate and a greater likelihood of a respiratory cause of cardiac arrest. In the small explorative subgroup, respiratory distress was the most common RRT trigger and delayed RRT activation was frequent. Early detection of respiratory abnormalities and timely interventions may have a potential to improve outcomes in RRT-reviewed patients and prevent further progress into IHCA.
