Abstract
Among patients with out-of-hospital cardiac arrest (OHCA), the influence of pre- and in-hospital factors on long-term survival, readmission, and resource utilization is ill-defined, mainly related to challenges combining disparate data sources. Adult nontraumatic OHCA from the British Columbia Cardiac Arrest Registry (January 2009 to December 2016) were linked to provincial datasets comprising comorbidities, medications, cardiac procedures, mortality, and hospital admission and discharge. Among hospital-discharge survivors, the 3-year end point of mortality or mortality and all-cause readmission was examined with the use of the Kaplan-Meier method and multivariable Cox regression model for predictors. The use of publicly funded home care and community services within 1 year after discharge also was evaluated. Of the 10,674 linked, emergency medical services-treated adult OHCAs, 3230 were admitted to hospital and 1325 survived to hospital discharge. At 3 years after discharge, the estimated Kaplan-Meier survival rate was 84.1% (95% CI 81.7%-86.1%) and freedom from death or all-cause readmission was 31.8% (29.0%-34.7%). After exclusions, 26.6% (n= 315/1186) accessed residential or home care services within 1 year. Independent predictors of long-term outcomes included age and comorbidities, but also favourable arrest characteristics and in-hospital factors such as revascularization or receipt of an intracardiac defibrillator before discharge. Among OHCA hospital survivors, the long-term death or readmission risk persists and is modulated by both pre- and in-hospital factors. However, only 1 in 4 survivors required residential or home care after discharge. These results support efforts to improve care processes to increase survival to hospital discharge.
