Abstract 18923: Trends in Long-term Survival After In-hospital Cardiac Arrest: Insights From Get With the Guidelines-Resuscitation®
Background: Although survival to hospital discharge after in-hospital cardiac arrest (IHCA) has improved over the last decade, it is unknown if these survival gains are sustained after hospital discharge. Accordingly, we evaluated temporal trends in 1-year survival after IHCA.
Methods: We linked data from Get With The Guidelines-Resuscitation (a national IHCA registry) with Medicare files and evaluated temporal trends in 1-year survival after IHCA between 2000 and 2011, using multivariable Poisson regression models to account for patient factors, clinical factors, cardiac arrest characteristics (e.g. initial rhythm, location of arrest), and hospital site. We examined 1-year survival trends overall, and separately for shockable (ventricular fibrillation [VF] and pulseless ventricular tachycardia [VT]) and non-shockable rhythms (asystole and pulseless electrical activity [PEA]).
Results: Of 45,567 patients with IHCA, the majority had a presenting rhythm of PEA (43.5%) or asystole (42.2%), and half (53.6%) occurred in an ICU. Overall 1-year survival was 9.4%, with higher survival each successive year (FIGURE). Risk-adjusted 1-year survival increased over time for all IHCA (adjusted rate ratio [RR] per year, 1.05; 95% confidence interval [CI], 1.04 to 1.06; P<0.001 for trend) and separately for VT/VF and PEA/asystole arrests (all p for trend <0.001). Compared with 2000-01, 1-year survival after IHCA in 2011 increased by 62% (adjusted RR, 1.62 [95% CI: 1.44-1.81]) (TABLE).
Conclusions: Over the past decade, 1-year survival after IHCA has significantly improved each year.
