- Background:Donation after brain death (DBD) is current praxis in Sweden. Circulatory death is far more common. Donation from patients suffering Out-of-Hospital Cardiac Arrest (OHCA) may have the potential to increase the organ-donor pool. The aim of this study was to describe the potential donor pool and its characteristics if uncontrolled donation after circulatory death (uDCD) were to be implemented in the metropolitan area of Stockholm, Sweden.Methods:A retrospective analysis was made using data from the Swedish Register for cardiopulmonary resuscitation (SRCR) between 2006 and 2015. Evaluation of potential organ donors was made using selection criteria from five previously published protocols concerning uDCD.Results:When applying different criteria from each of the five studied protocols in a total of 9,793 cases of OHCA, between 7.5% (n = 732) and 1.5% (n = 150) of the patients were found to be potential candidates for uDCD. The median age of the sampled uDCD candidates in each protocol was between 48 and 57 years. Male donors were found in 67–76% of all cases.Conclusion:Although not taking important real-life limitations into account, our results indicate that implementation of a uDCD programme may substantially increase the number of potential organ donors in Stockholm.

- AIM: Reports on differences between respondents and non-respondents of out-of-hospital cardiac arrest (OHCA) survivors are sparse. This study compares respondents with non-respondents in a follow-up study of a consecutive sample of OHCA survivors and describes the relation between respondents' self-reported morbidity and health.METHODS/DESIGN: Questionnaires were administered within 12 months after the OHCA. The study population was adult patients who had survived an OHCA during 2008 to 2011, with a cerebral performance score of ≤2 at discharge. The patients were identified through the Swedish registry of OHCA. The Self-administered comorbidity questionnaire and EQ VAS (Euroqol questionnaire visual analogue scale) was used to measure morbidity and health status.RESULTS: Of 298 survivors, 224 were eligible for the study and 127 responded. Mean time from cardiac arrest (CA) to follow up was 178 days. Comparing the 127 respondents with the 97 lost to follow-up and non-respondents, no significant differences were found in terms of age, sex, factors at resuscitation and in-hospital interventions. The EQ VAS median was 75 (25th,75th percentile 60,80)). Self-rated health differed between respondents reporting 0-2 conditions (n=68) and respondents reporting more than two (n=43), median EQ VAS 78 (68,90) and 65 (50,80)), respectively; p-value 0.0001.CONCLUSIONS: Despite a limited response rate, representativeness in terms of patient characteristics among survivors of OHCA with an acceptable cerebral function is achievable. A considerable proportion of the survivors lived with the burden of multi-morbidity which worsened health.

- 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.

- OBJECTIVE: To describe the prevalence, baseline characteristics and factors associated with survival in out-of-hospital cardiac arrest (OHCA) with initial non-shockable rhythm sub-grouped into pulseless electrical activity (PEA) and asystole as presenting rhythm.METHODS: The Swedish Registry of Cardiopulmonary Resuscitation is a prospectively recorded nationwide registry of modified Utstein parameters, including all patients with attempted resuscitation after OHCA. Data between 1990-2016 were analyzed.RESULTS: After exclusions, the study population consisted of 48,707 patients presenting with either PEA or asystole. The proportion of PEA increased from 12% to 22% during the study period with a fivefold increase in 30-day survival reaching 4.9%. Survival in asystole showed a modest increase from 0.6% to 1.3%. In the multivariable analysis, PEA was independently associated with survival at 30 days (OR 1.54, 95% CI 1.26-1.88).CONCLUSION: Between 1990 and 2016, the proportion of PEA as the first recorded rhythm doubled with a five-fold increase in 30-day survival, while survival among patients with asystole remained at low levels. PEA and asystole should be considered separate entities in clinical decision-making and be reported separately in observational studies and clinical trials.

- Aim: To examine the psychometric properties of a modified version of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), for a cardiac arrest population (IQCODE-CA). Methods: The IQCODE-CA, a 26-item observer-reported questionnaire, was completed by informants, defined as relatives or close friends, of 268 out-of-hospital cardiac arrest (OHCA) survivors who participated in the Target Temperature Management trial in a scheduled follow-up 180 +/- 14 days after OHCA. Survivors completed the Mini Mental State Examination (MMSE), the Rivermead Behavioural Memory Test (RBMT) and the Hospital Anxiety and Depression Scale (HADS). An exploratory factor analysis was performed. Associations between IQCODE-CA results and demographic variables along with other instruments were calculated. Area under the curve (AUC) ratios were evaluated to examine discrimination. Results: The IQCODE-CA measured one factor, global cognitive decline, with high internal consistency (ordinal alpha = 0.95). Age, gender or education did not influence the IQCODE-CA score. Associations with performance-based measures of global cognitive function as well as anxiety and depression ranged from small to moderate (rs = -0.29 to 0.38). AUC ratios ranged from fair to good (0.72-0.81). According to the MMSE and RBMT, the optimal cut-off score to identify cognitive decline on the IQCODE-CA was 3.04. Using this value, 53% of the survivors were under the cut-off. Conclusions: The IQCODE-CA identified a large amount of survivors with possible cognitive problems, making it useful when screening for cognitive decline post-CA. Due to lower AUC ratios than desired, additional performance-based measures should be used to improve the overall screening methodology. (C) 2017 Elsevier B.V. All rights reserved.

- Aim:To describe the detailed health-related quality of life (HRQoL) in survivors from the TTM-trial and to investigate potential differences related to sex and age.Methods:This is a cross-sectional study originating from a large prospective international, multicentre trial, including 442 respondents who answered the Short Form-36 item Questionnaire Health Survey version 2® (SF-36v2®) at a structured follow-up 6 months after out-of-hospital cardiac arrest (OHCA). Statistical analysis between independent groups were performed with Mann-Whitney U or Chi-square. Age was analysed primarily as a dichotomised variable.Results:Although overall physical and mental health were within the normal range, a substantial proportion of respondents had impaired function at domain-specific levels, particularly in Role-Physical (50%) and Role-Emotional (35%). Females scored significantly lower than males in; Physical Functioning (41.7 vs. 47.9, p < 0.001), Role-Physical (40.4 vs. 44.3, p = 0.02), General Health (47.0 vs. 50.5, p = 0.02), Vitality (47.2 vs. 52.7, p < 0.001), and Role-Emotional (41.5 vs. 46.2, p = 0.009). Those ≤65 years scored significantly better in Physical Functioning (47.9 vs. 44.1 p < 0.001), while those >65 years scored significantly better in Vitality (50.8 vs. 53.7, p = 0.006) and Mental Health (50.3 vs. 52.6, p = 0.04).Conclusions:Many OHCA survivors demonstrated impaired function in HRQoL at a domain level, despite most patients reporting an acceptable general HRQoL. Females reported worse HRQoL than males. Older age was associated with a worse Physical Functioning but better Vitality and Mental Health. Role-Physical and Role-Emotional aspects of health were especially affected, even when effects of age and sex where accounted for.
