Health-related quality of life in critically ill survivors: specific impact of cardiac arrest in non-shockable rhythm.

ABSTRACT:

Background

Intensive care has a strong impact on health-related quality of life (HRQOL). The specific impact of cardiac arrest in non-shockable rhythm is poorly known.

Patients and methods

We gathered patients included in two randomized controlled trials (AWARE and HYPERION). The HYPERION trial included ICU-treated non-shockable cardiac arrest patients. The AWARE study included ICU patients requiring mechanical ventilation. We compared the 3-months HRQOL of these patients to those of a large sample of the French general population. Physical and mental dimension were compared. Multivariable linear regression was used to pick up factors associated with HRQOL.

Results

72 and 307 patients of the HYPERION and the AWARE studies were compared to 20,574 French controls. ICU patients evidenced lower scores in all the SF-36 dimensions compared to the controls. Similar scores were observed in both HYPERION and AWARe trials. The physical component score was lower in patients from the HYPERION trial compared to those from the AWARE trials and to controls (38.6 [29.6-47.8], 35.4 [27.5-46.4] vs. 53.0 [46.0-56.7], [Formula: see text]). After adjustment for age and gender, HYPERION and AWARE trial status were associated wit lower physical component score.

Conclusion

Health-related quality of life of unshockable cardiac arrest survivors evaluated at 3 months was similar to ICU survivors and significantly lower than in individuals from general population, especially in the physical dimensions.

Project description:BackgroundSingapore and Osaka in Japan have comparable population sizes and prehospital management; however, the frequency of ECPR differs greatly for out-of-hospital cardiac arrest (OHCA) patients with initial shockable rhythm. Given this disparity, we hypothesized that the outcomes among the OHCA patients with initial shockable rhythm in Singapore were different from those in Osaka. The aim of this study was to evaluate the outcomes of OHCA patients with initial shockable rhythm in Singapore compared to the expected outcomes derived from Osaka data using machine learning-based prediction models.MethodsThis was a secondary analysis of two OHCA databases: the Singapore PAROS database (SG-PAROS) and the Osaka-CRITICAL database from Osaka, Japan. This study included adult (18-74 years) OHCA patients with initial shockable rhythm. A machine learning-based prediction model was derived and validated using data from the Osaka-CRITICAL database (derivation data 2012-2017, validation data 2018-2019), and applied to the SG-PAROS database (2010-2016 data), to predict the risk-adjusted probability of favorable neurological outcomes. The observed and expected outcomes were compared using the observed-expected ratio (OE ratio) with 95% confidence intervals (CI).ResultsFrom the SG-PAROS database, 1,789 patients were included in the analysis. For OHCA patients who achieved return of spontaneous circulation (ROSC) on hospital arrival, the observed favorable neurological outcome was at the same level as expected (OE ratio: 0.905 [95%CI: 0.784-1.036]). On the other hand, for those who had continued cardiac arrest on hospital arrival, the outcomes were lower than expected (shockable rhythm on hospital arrival, OE ratio: 0.369 [95%CI: 0.258-0.499], and nonshockable rhythm, OE ratio: 0.137 [95%CI: 0.065-0.235]).ConclusionThis observational study found that the outcomes for patients with initial shockable rhythm but who did not obtain ROSC on hospital arrival in Singapore were lower than expected from Osaka. We hypothesize this is mainly due to differences in the use of ECPR.

Project description:Background and importanceBystander cardiopulmonary resuscitation (CPR) and initial shockable rhythm are crucial predictors of survival after out-of-hospital cardiac arrest (OHCA). However, the relationship between dispatcher-assisted CPR (DA-CPR) and initial shockable rhythm is not completely elucidated.ObjectiveTo examine the association of DA-CPR with initial shockable rhythm and outcomes.Design, setting and participantsThis nationwide population-based observational study conducted in Japan included 59 688 patients with witnessed OHCA of cardiac origin after excluding those without bystander CPR. Patients were divided into DA-CPR (n = 42 709) and CPR without dispatcher assistance (unassisted CPR, n = 16 979) groups.Outcome measures and analysisThe primary outcome measure was initial shockable rhythm, and secondary outcome measures were 1-month survival and neurologically intact survival. A Cox proportional hazards model adjusted for collapse-to-first-rhythm-analysis time and multivariable logistic regression models were used after propensity score (PS) matching to compare the incidence of initial shockable rhythm and outcomes, respectively.Main resultsAmong all patients (mean age 76.7 years), the rates of initial shockable rhythm, 1-month survival and neurologically intact survival were 20.8, 10.7 and 7.0%, respectively. The incidence of initial shockable rhythm in the DA-CPR group (20.4%, 3462/16 979) was significantly higher than that in the unassisted CPR group (18.5%, 3133/16 979) after PS matching (P < 0.0001). However, no significant differences were found between the two groups with respect to the incidence of initial shockable rhythm in the Cox proportional hazards model [adjusted hazard ratio of DA-CPR for initial shockable rhythm compared with unassisted CPR, 0.99; 95% confidence interval (CI), 0.97-1.02, P = 0.56]. No significant differences were observed in the survival rates in the two groups after PS matching [10.8% (1833/16 979) vs. 10.3% (1752/16 979), P = 0.16] and neurologically intact survival rates [7.3% (1233/16 979) vs. 6.8% (1161/16 979), P = 0.13]. The multivariable logistic regression model showed no significant differences between the groups with regard to survival (adjusted odds ratio of DA-CPR compared with unassisted CPR: 1.00; 95% CI, 0.89-1.13, P = 0.97) and neurologically intact survival (adjusted odds ratio: 1.12; 95% CI, 0.98-1.29, P = 0.14).ConclusionDA-CPR after OHCA had the same independent association with the likelihood of initial shockable rhythm and 1-month meaningful outcome as unassisted CPR.

Project description:ImportanceDelayed defibrillation (>2 minutes) in adult in-hospital cardiac arrest (IHCA) is associated with worse outcomes. Little is known about the timing and outcomes of defibrillation in pediatric IHCA.ObjectiveTo determine whether time to first defibrillation attempt in pediatric IHCA with a first documented shockable rhythm is associated with survival to hospital discharge.Design, setting, and participantsIn this cohort study, data were obtained from the Get With The Guidelines-Resuscitation national registry between January 1, 2000, and December 31, 2015, and analyses were completed by October 1, 2017. Participants were pediatric patients younger than 18 years with an IHCA and a first documented rhythm of pulseless ventricular tachycardia or ventricular fibrillation and at least 1 defibrillation attempt.ExposuresTime between loss of pulse and first defibrillation attempt.Main outcomes and measuresThe primary outcome was survival to hospital discharge. Secondary outcomes were return of circulation, 24-hour survival, and favorable neurologic outcome at hospital discharge.ResultsAmong 477 patients with a pulseless shockable rhythm (median [interquartile range] age, 4 years [3 months to 14 years]; 285 [60%] male), 338 (71%) had a first defibrillation attempt at 2 minutes or less after pulselessness. Children were less likely to be shocked in 2 minutes or less for ward vs intensive care unit IHCAs (48% [11 of 23] vs 72% [268 of 371]; P = .01]). Thirty-eight percent (179 patients) survived to hospital discharge. The median (interquartile range) reported time to first defibrillation attempt was 1 minute (0-3 minutes) in both survivors and nonsurvivors. Time to first defibrillation attempt was not associated with survival in unadjusted analysis (risk ratio [RR] per minute increase, 0.96; 95% CI, 0.92-1.01; P = .15) or adjusted analysis (RR, 0.99; 95% CI, 0.94-1.06; P = .86). There was no difference in survival between those with a first defibrillation attempt in 2 minutes or less vs more than 2 minutes in unadjusted analysis (132 of 338 [39%] vs 47 of 139 [34%]; RR, 0.87; 95% CI, 0.66-1.13; P = .29) or multivariable analysis (RR, 0.99; 95% CI, 0.75-1.30; P = .93). Time to first defibrillation attempt was also not associated with secondary outcome measures.Conclusions and relevanceIn contrast to published adult IHCA and pediatric out-of-hospital cardiac arrest data, no significant association was observed between time to first defibrillation attempt in pediatric IHCA with a first documented shockable rhythm and survival to hospital discharge.
