- 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.

Prehospital Diagnosis and Oxygen Treatment in ST Elevation Myocardial Infarction
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- IntroductionPaper I: An Artificial Neural Network (ANN) was constructed to identify ST Elevation Myocardial Infarction (STEMI) and predict the need for Percutaneous Coronary Intervention (PCI). Paper II, III and IV: Studies suggest that O2 therapy may be harmful in STEMI patients. We therefore conducted the SOCCER study to evaluate the effects of O2 therapy in STEMI patients.MethodsPaper I: 560 ambulance ECGs sent to the Cardiac Care Unit (CCU), was together with the CCU physicians interpretation and decision of conducting an acute PCI or not collected, and compared with the interpretation and PCI decision of the ANN. Paper II, III, IV: Normoxic (≥94%) STEMI patients accepted for acute PCI were in the ambulance randomized to standard care with 10 L/min O2 or room air. A subset of the patients underwent echocardiography for determination of the Left Ventricular Ejection Fraction (LVEF) and the Wall Motion Score Index (WMSI). All patients had a Cardiac Magnetic Resonance Imaging (CMRI) to evaluate Myocardial area at Risk (MaR), Infarct Size (IS) and Myocardial Salvage Index (MSI).ResultsPaper I: The area under the ANN’s receiver operating characteristics curve for STEMI detection as well as predicting the need of acute PCI were very good.Paper II, III, IV: No significant differences could be shown in discussing MaR, MSI or IS between the O2 group (n=46) and the air group (n=49). Neither could any differences be shown for LVEF and WMSI at the index visit as well after six months between the O2 group (n=46) and the air group (n=41)ConclusionsPaper I: The results indicate that the number of ECGs sent to the CCU could be reduced with 2/3 as the ANN would safely identify ECGs not being STEMI.Paper II, III, IV: The results suggest that it is safe to withhold O2 therapy in normoxic, stable STEMI patients.

- In high-income countries a large proportion of all deaths occur in hospitals. A common way to translate knowledge into clinical practice is developing guidelines for different levels of health care organisations. During 2012, national clinical guidelines for palliative care were published in Sweden. Later, guidance for palliative care was issued by the National Board of Health and Welfare. The aim of this study was two-fold: to investigate perceptions regarding these guidelines and identify obstacles and opportunities for implementation of them in acute care hospitals. Interviews were conducted with local politicians, chief medical officers and health professionals at acute care hospitals. The Consolidated Framework for Implementation Research was used in a directed content analysis approach. The results showed little knowledge of the two documents at all levels of the health care organisation. Palliative care was primarily described as end of life care and only few of the participants talked about the opportunity to integrate palliative care early in a disease trajectory. The environment and culture at hospitals, characterised by quick decisions and actions, were perceived as obstacles to implementation. Health professionals' expressed need for palliative care training is an opportunity for implementation of clinical guidelines. There is a need for further implementation of palliative care in hospitals. One option for further research is to evaluate implementation strategies tailored to acute care. © 2017 Elsevier B.V.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundStudies have addressed the effect of multimodal pain rehabilitation (MMR), whereas criteria for selection are sparse. This study examines whether higher scores on musculoskeletal pain measures are associated with selection to MMR, and whether this differs across gender. MethodA clinical population of 262 male and 589 female patients was recruited consecutively during 3 years, 2007-2010. The patients were referred from primary care to a pain rehabilitation clinic in Northern Sweden for assessment and selection to MMR. Register-based data on self-reported pain were linked to patients' records where outcome (MMR or not) was stated. We modelled odds ratios for selection to MMR by higher scores on validated pain measures (pain severity, interference with daily life, pain sites and localized pain vs. varying pain location). Covariates were age, educational level and multiple pain measures. Anxiety and depression (Hospital, Anxiety and Depression Scale) and working status were used in sensitivity tests. ResultsHigher scores of self-reported pain were not associated with selection to MMR in multivariate models. Among women, higher scores on pain severity, pain sites and varying pain location (localized pain=reference) were negatively associated with selection to MMR. After adjustment for multiple pain measures, the negative odds ratio for varying location persisted (OR=0.59, 95% CI=0.39-0.89). ConclusionHigher scores on self-reported pain did not guide selection to MMR and a negative trend was found among women. Studies of referral patterns and decision processes may contribute to a better understanding of the clinical practice that decides selection to MMR.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundClinical pathways can enhance care quality, promote patient safety and optimize resource utilization. However, they are infrequently utilized in intensive care. This study aimed to explain the implementation process of a clinical pathway based on a bottom-up approach in an intensive care context.MethodsThe setting was an 11-bed general intensive care unit in Sweden. An action research project was conducted to implement a clinical pathway for patients on mechanical ventilation. The project was managed by a local interprofessional core group and was externally facilitated by two researchers. Grounded theory was used by the researchers to explain the implementation process. The sampling in the study was purposeful and theoretical and included registered nurses (n31), assistant nurses (n26), anesthesiologists (n11), a physiotherapist (n1), first- and second-line managers (n2), and health records from patients on mechanical ventilation (n136). Data were collected from 2011 to 2016 through questionnaires, repeated focus groups, individual interviews, logbooks/field notes and health records. Constant comparative analysis was conducted, including both qualitative data and descriptive statistics from the quantitative data.ResultsA conceptual model of the clinical pathway implementation process emerged, and a central phenomenon, which was conceptualized as Struggling for a feasible tool,' was the core category that linked all categories. The phenomenon evolved from the Triggers' (Perceiving suboptimal practice' and Receiving external inspiration and support'), pervaded the Implementation process' (Contextual circumstances,' Processual circumstances' and Negotiating to achieve progress'), and led to the process Output' (Varying utilization' and Improvements in understanding and practice'). The categories included both facilitating and impeding factors that made the implementation process tentative and prolonged but also educational.ConclusionsThe findings provide a novel understanding of a bottom-up implementation of a clinical pathway in an intensive care context. Despite resonating well with existing implementation frameworks/theories, the conceptual model further illuminates the complex interaction between different circumstances and negotiations and how this interplay has consequences for the implementation process and output. The findings advocate a bottom-up approach but also emphasize the need for strategic priority, interprofessional participation, skilled facilitators and further collaboration.

Biomarkers for Better Understanding of the Pathophysiology and Treatment of Chronic Pain : Investigations of Human Biofluids
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Chronic pain affects 20 % of the global population, causes suffering, is difficult to treat, and constitutes a large economic burden for society. So far, the characterization of molecular mechanisms of chronic pain-like behaviors in animal models has not translated into effective treatments.In this thesis, consisting of five studies, pain patient biofluids were analyzed with modern proteomic methods to identify biomarker candidates that can be used to improve our understanding of the pathophysiology chronic pain and lead to more effective treatments.Paper I is a proof of concept study, where a multiplex solid phase-proximity ligation assay (SP-PLA) was applied to cerebrospinal fluid (CSF) for the first time. CSF reference protein levels and four biomarker candidates for ALS were presented. The investigated proteins were not altered by spinal cord stimulation (SCS) treatment for neuropathic pain. In Paper II, patient CSF was explored by dimethyl and label-free mass spectrometric (MS) proteomic methods. Twelve proteins, known for their roles in neuroprotection, nociceptive signaling, immune regulation, and synaptic plasticity, were identified to be associated with SCS treatment of neuropathic pain. In Paper III, proximity extension assay (PEA) was used to analyze levels of 92 proteins in serum from patients one year after painful disc herniation. Patients with residual pain had significantly higher serum levels of 41 inflammatory proteins. In Paper IV, levels of 55 proteins were analyzed by a 100-plex antibody suspension bead array (ASBA) in CSF samples from two neuropathic pain patient cohorts, one cohort of fibromyalgia patients and two control cohorts. CSF protein profiles consisting of levels of apolipoprotein C1, ectonucleotide pyrophosphatase/phosphodiesterase family member 2, angiotensinogen, prostaglandin-H2 D-isomerase, neurexin-1, superoxide dismutases 1 and 3 were found to be associated with neuropathic pain and fibromyalgia. In Paper V, higher CSF levels of five chemokines and LAPTGF-beta-1were detected in two patient cohorts with neuropathic pain compared with healthy controls.In conclusion, we demonstrate that combining MS proteomic and multiplex antibody-based methods for analysis of patient biofluid samples is a viable approach for discovery of biomarker candidates for the pathophysiology and treatment of chronic pain. Several biomarker candidates possibly reflecting systemic inflammation, lipid metabolism, and neuroinflammation in different pain conditions were identified for further investigation.

- This study aimed to describe and explain teamwork and factors that influence team processes in everyday practice in an intensive care unit (ICU) from a staff perspective. The setting was a Swedish ICU. Data were collected from 38 ICU staff in focus groups with registered nurses, assistant nurses, and anaesthetists, and in one individual interview with a physiotherapist. Constant comparative analysis according to grounded theory was conducted, and to identify the relations between the emerged categories, the paradigm model was applied. The core category to emerge from the data was balancing intertwined responsibilities. In addition, eleven categories that related to the core category emerged. These categories described and explained the phenomenon's contextual conditions, causal conditions, and intervening conditions, as well as the staff actions/interactions and the consequences that arose. The findings indicated that the type of teamwork fluctuated due to circumstantial factors. Based on the findings and on current literature, strategies that can optimise interprofessional teamwork are presented. The analysis generated a conceptual model, which aims to contribute to existing frameworks by adding new dimensions about perceptions of team processes within an ICU related to staff actions/interactions. This model may be utilised to enhance the understanding of existing contexts and processes when designing and implementing interventions to facilitate teamwork in the pursuit of improving healthcare quality and patient safety.

- Animal models suggest that chemokines are important mediators in the pathophysiology of neuropathic pain. Indeed, these substances have been called “gliotransmitters,” a term that illustrates the close interplay between glial cells and neurons in the context of neuroinflammation and pain. However, evidence in humans is scarce. The aim of the study was to determine a comprehensive cerebrospinal fluid (CSF) inflammatory profile of patients with neuropathic pain. Our hypothesis was that we would thereby find indications of a postulated on-going process of central neuroinflammation. Samples of CSF were collected from 2 cohorts of patients with neuropathic pain (n = 11 and n = 16, respectively) and healthy control subjects (n = 11). The samples were analyzed with a multiplex proximity extension assay in which 92 inflammation-related proteins were measured simultaneously (Proseek Multiplex Inflammation I; Olink Bioscience, Uppsala, Sweden). Univariate testing with control of false discovery rate, as well as orthogonal partial least squares discriminant analysis, were used for statistical analyses. Levels of chemokines CXCL6, CXCL10, CCL8, CCL11, CCL23 in CSF, as well as protein LAPTGF-beta-1, were significantly higher in both neuropathic pain cohorts compared with healthy controls, pointing to neuroinflammation in patients. These 6 proteins were also major results in a recent similar study in patients with fibromyalgia. The findings need to be confirmed in larger cohorts, and the question of causality remains to be settled. Because it has been suggested that prevalent comorbidities to chronic pain (eg, depression, anxiety, poor sleep, and tiredness) also are associated with neuroinflammation, it will be important to determine whether neuroinflammation is a common mediator.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Breathing exercises with positive expiratory pressure (PEP) are used to improve pulmonary function and airway clearance. Different PEP devices are available, but there have been no studies that describe the pressure generated by different resistors. The purpose of this study was to compare pressures generated from the proprietary resistor components of 4 commercial flow-dependent PEP valves with all other parameters kept constant. METHODS: Resistors from 4 flow-regulated PEP devices (Pep/Rmt system, Wellspect HealthCare; Pipe P breathing exerciser, Koo Medical Equipment; Mini-PEP, Philips Respironics [including resistors by Rusch]; and 15-mm endo-adapter, VBM Medizintechnik) were tested randomly by a blinded tester at constant flows of 10 and 18 L/min from an external gas system. All resistors were tested 3 times. RESULTS: Resistors with a similar diameter produced statistically significant different pressures at the same flow. The differences were smaller when the flow was 10 L/min compared with 18 L/min. The differences were also smaller when the diameter of the resistor was increased. The pressures produced by the 4 resistors of the same size were all significantly different when measuring 1.5- and 2.0-mm resistors at a flow of 10 L/min and 2.0-mm resistors at a flow of 18 L/min (P < .001). There were no significant differences between any of the resistors when testing sizes of 4.5 and 5.0 mm at either flow. The Mini-PEP and adapter resistors gave the highest pressures. CONCLUSIONS: Pressures generated by the different proprietary resistor components of 4 commercial PEP devices were not comparable, even though the diameter of the resistors is reported to be the same. The pressures generated were significantly different, particularly when using small-diameter resistors at a high flow. Therefore, the resistors may not be interchangeable. This is important information for clinicians, particularly when considering PEP for patients who do not tolerate higher pressures. (C) 2015 Daedalus Enterprises

Traumatic cardiac arrest in Sweden 1990-2016 : a population-based national cohort study
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Background: Trauma is a main cause of death among young adults worldwide. Patients experiencing a traumatic cardiac arrest (TCA) certainly have a poor prognosis but population-based studies are sparse. Primarily to describe characteristics and 30-day survival following a TCA as compared with a medical out-of-hospital cardiac arrest (medical CA). Methods: A cohort study based on data from the nationwide, prospective population-based Swedish Registry for Cardiopulmonary Resuscitation (SRCR), a medical cardiac arrest registry, between 1990 and 2016. The definition of a TCA in the SRCR is a patient who is unresponsive with apnoea where cardiopulmonary resuscitation and/or defibrillation have been initiated and in whom the Emergency Medical Services (EMS, mainly a nurse-based system) reported trauma as the aetiology. Outcome was overall 30-day survival. Descriptive statistics as well as multivariable logistic regression models were used. Results: In all, between 1990 and 2016, 1774 (2.4%) cases had a TCA and 72,547 had a medical CA. Overall 30-day survival gradually increased over the years, and was 3.7% for TCAs compared to 8.2% following a medical CA (p < 0.01). Among TCAs, factors associated with a higher 30-day survival were bystander witnessed and having a shockable initial rhythm (adjusted OR 2.67, 95% C.I. 1.15-6.22 and OR 8.94 95% C.I. 4.27-18.69, respectively). Discussion: Association in registry-based studies do not imply causality but TCA had short time intervals in the chain of survival as well as high rates of bystander-CPR. C onclusion: In a medical CA registry like ours, prevalence of TCAs is low and survival is poor. Registries like ours might not capture the true incidence. However, many individuals do survive and resuscitation in TCAs should not be seen futile.
