Background: Previous studies among cancer patients have demonstrated that religious patients receive more aggressive end-of-life (EOL) care. We sought to examine the effect of religious affiliation on EOL care in the intensive care unit (ICU) setting.
Materials and methods: We conducted a retrospective review of all patients admitted to any adult ICU at a tertiary academic center in 2010 requiring at least 2 d of mechanical ventilation. EOL patients were those who died within 30 d of admission. Hospital charges, ventilator days, hospital days, and days until death were used as proxies for intensity of care among the EOL patients. Multivariate analysis using multiple linear regression, zero-truncated negative binomial regression, and Cox proportional hazard model were used.
Results: A total of 2013 patients met inclusion criteria; of which, 1355 (67%) affirmed a religious affiliation. The EOL group had 334 patients, with 235 (70%) affirming a religious affiliation. The affiliated and nonaffiliated patients had similar levels of acuity. Controlling for demographic and medical confounders, religiously affiliated patients in the EOL group incurred 23% (P = 0.030) more hospital charges, 25% (P = 0.035) more ventilator days, 23% (P = 0.045) more hospital days, and 30% (P = 0.036) longer time until death than their nonaffiliated counterparts. Among all included patients, survival did not differ significantly among affiliated and nonaffiliated patients (log-rank test P = 0.317), neither was religious affiliation associated with a difference in survival on multivariate analysis (hazard ratio of death for religious versus nonreligious patients 0.95, P = 0.542).
Conclusions: Compared with nonaffiliated patients, religiously affiliated patients receive more aggressive EOL care in the ICU. However, this high-intensity care does not translate into any significant difference in survival.
