Strategies for Post Cardiac Arrest Care were developed based on evidence from OHCA. The aim of this study was to compare characteristics and outcomes in patients admitted to intensive care after IHCA and OHCA. Methods: A retrospective multicenter observational study of adult survivors of cardiac arrest admitted to intensive care in southern Sweden between 2014-2018. Data was collected from registries and medical notes. The primary outcome was neurological outcome according to the Cerebral Performance Category (CPC) scale at 2-6 months. Results: 799 patients were included, 245 IHCA and 554 OHCA. IHCA patients were older, less frequently male and less frequently without comorbidity. In IHCA the first recorded rhythm was more often non-shockable, all delay-times (ROSC, no-flow, low-flow, time to advanced life support) were shorter and a cardiac cause of the arrest was less common. Good long-term neurological outcome was more common after IHCA than OHCA. In multivariable analysis, witnessed arrest, age, shorter arrest duration (no-flow and low-flow times), low lactate, shockable rhythm, and a cardiac cause were all independent predictors of good long-term neurological outcome whereas location of arrest (IHCA vs OHCA) was not. Conclusion: In patients admitted to intensive care after cardiac arrest, patients who suffered IHCA vs OHCA differed in demographics, comorbidities, cardiac arrest characteristics and outcomes. In multivariable analyses, cardiac arrest characteristics were independent predictors of outcome, whereas location of arrest (IHCA vs OHCA) was not.

We conducted this study to describe and compare the effects of pre-hospital airway management on survival outcomes for paediatric OHCA in the Asia-pacific region. Methods: We performed a retrospective analysis of the Pan Asian Resuscitation Outcomes Study (PAROS) data from January 2009 to June 2018. PAROS is a prospective, observational, multi-centre cohort study from eleven countries. The primary outcomes were one-month survival and survival with favourable neurological status, defined as Cerebral Performance Category1 or 2. We performed multivariate analyses of the unmatched and propensity matched cohort. Results: We included 3131 patients less than 18 years in the study. 2679 (85.6%) children received bag-valve-mask (BVM) ventilations, 81 (2.6%) endotracheal intubations (ETI) and 371 (11.8%) supraglottic airways (SGA). 792 patients underwent propensity score matching. In the matched cohort, advanced airway management (AAM: SGA and ETI) when compared with BVM group was associated with decreased one-month survival [AAM: 28/396 (7.1%) versus BVM: 55/396 (13.9%); adjusted odds ratio (aOR), 0.46 (95% CI, 0.29 - 0.75); p = 0.002] and survival with favourable neurological status [AAM: 8/396 (2.0%) versus BVM: 31/396 (7.8%); aOR, 0.22 (95% CI, 0.10- 0.50); p < 0.001]. For SGA group, we observed less 1-month survival [SGA: 24/337 (7.1%) versus BVM: 52/337 (15.4%); aOR, 0.41 (95 %CI, 0.25-0.69), p = 0.001] and survival with favourable neurological status. Conclusion: In children with OHCA in the Asia-Pacific region, pre-hospital AAM was associated with decreased one-month survival and less favourable neurological status.

This systematic review and meta-analysis aimed to determine the risk of recurrence after sudden cardiac arrest and its associated risk factors. Methods: Medline, Embase, Cochrane Library and Scopus were searched from inception to October 2021. Studies involving survivors of an out-of-hospital sudden cardiac arrest event of any non-traumatic aetiology were included. Meta-analyses of proportions using the random-effects model estimated the primary outcome of first recurrent sudden cardiac arrest incidence as well as secondary outcomes including cumulative incidence of recurrence at 1-year and incidence of second recurrence among survivors of first recurrence. A recurrent episode was defined as a sudden cardiac arrest that occurs 28 or more days after the index event. Subgroup and meta-regression analyses were conducted for predetermined variables. The Newcastle-Ottawa Scale was used to assess risk of bias for most studies. Results: 35 studies of moderate to high quality comprising a total of 7186 survivors were analysed. The pooled incidence of first recurrence was 15.24% (32 studies; 95%CI, 11.01-19.95; mean follow-up time, 41.3 +/- 29.3 months) and second recurrence was 35.03% (3 studies; 95%CI, 19.65-51.93; mean follow-up time, 161.1 +/- 54.3 months). At 1-year, incidence of recurrence was 10.62% (3 studies; 95%CI, 0.25-30.42). Subgroup analyses found no significant difference (p= 0.204) between incidence of first recurrence published from 1975-1992 and 1993-2021, and between studies with mean follow-up time of <24 months, 24-48 months, and >48 months. On meta-regression, initial shockable rhythm increased incidence of first recurrence (p = 0.01). Conclusion: 15.24% of sudden cardiac arrest survivors experienced a recurrence, and of these, 35.03% experienced a second recurrence. Most recurrences occurred in the first year. Initial shockable rhythm increased this risk. Despite the limitations of inter-study heterogeneity, these findings can still guide intervention and follow-up of sudden cardiac arrest survivors.

We sought to validate the CaRdiac Arrest Survival Score (CRASS), derived using data from the German Resuscitation Registry, in predicting the likelihood of good neurological outcomes after OHCA in Singapore. Methods: We conducted a retrospective population-based validation study among EMS-attended OHCA patients (>18 years) in Singapore, using data from the prospective Pan-Asian Resuscitation Outcomes Study registry. Good neurological outcome was defined as a cerebral performance category of 1 or 2. To evaluate the CRASS score in light of the difference in patient characteristics, we used the default constant coefficient (0.8) and the adjusted coefficient (0.2) to calculate the probability of good neurological outcomes. Results: Out of 11,404 analyzed patients recruited between April 2010 and December 2018, 260 had good and 11,144 had poor neurological function. The CRASS score demonstrated good discrimination, with an area under the curve of 0.963 (95% confidence interval: 0.952-0.974). Using the default constant coefficient of 0.8, the CRASS score consistently overestimated the predicted probability of a good outcome. Following adjustment of the coefficient to 0.2, the CRASS score showed improved calibration. Conclusion: CRASS demonstrated good discrimination and moderate calibration in predicting favorable neurological outcomes in the validation Singapore cohort. Our study established a good foundation for future large-scale, cross-country validations of the CRASS score in diverse socio
