Ethnic and sex-based differences in outcomes after out-of-hospital cardiac arrest: a glimpse of the largest municipal healthcare system in the United States.
Cardiovascular Diagnosis and Therapy 2023 Februrary 29
BACKGROUND: Ethnic and sex-based disparity in outcomes after out-of-hospital cardiac arrest (OHCA) may exist and could be due to social factors and inequality in care. We aimed to study whether ethnic and sex-based differences in out-of-hospital cardiac arrest outcomes occurred in a safety net hospital within the largest municipal healthcare system in the United States.
METHODS: We conducted a retrospective cohort study of patients successfully resuscitated from an OHCA and brought to New York City Health + Hospitals/Jacobi, from January 2019 to September 2021. Out-of-hospital cardiac arrest characteristics, do not resuscitate and withdrawal of life-sustaining therapy orders, and disposition data were collected and analyzed using regression models.
RESULTS: Out of 648 patients screened, 154 were included (48.1% women). On multivariable analysis, sex [odds ratio (OR): 0.84; 95% CI: 0.30-2.4; P=0.74] and ethnic background (OR: 0.80; 95% CI: 0.58-1.12; P=0.196) did not predict discharge survival. No significant sex difference in do not resuscitate (P=0.76) or withdrawal of life-sustaining therapy (P=0.39) orders was found. Younger age (OR: 0.96; P=0.04) and initial shockable rhythm (OR: 7.26; P=0.01) independently predicted survival, both at discharge and at one year.
CONCLUSIONS: Among patients resuscitated after an out-of-hospital cardiac arrest, neither sex nor ethnic background predicted discharge survival and no sex differences in end-of-life preferences were found. These findings are distinct from those of previously published reports. Given the unique population studied, distinct from those of registry-based studies, socioeconomic factors likely served as bigger drivers of out-of-hospital cardiac arrest outcomes rather than ethnic background or sex.
