The prognostic significance of chronic medical illness in comatose survivors of cardiac arrest who undergo targeted temperature management (TTM) remains largely unknown. We sought to assess the association between overall burden of pre-existing medical comorbidity and neurological outcomes in survivors of cardiac arrest undergoing TTM. We analyzed a prospectively collected cohort of 314 patients treated with TTM following cardiac arrest at a tertiary care hospital between 2007 and 2014. ⋯ In multivariable logistic regression, elevated CCI scores were not associated with increased odds of poor neurological outcomes (OR 1.04, 95% CI 0.90-1.19, p = 0.608) or death (OR 0.99, 95% CI 0.86-1.13, p = 0.816) at hospital discharge. No association was seen between CCI scores and death at 1-year post-arrest (OR 1.09, 95% CI 0.95-1.26, p = 0.220). Increasing burden of medical comorbidity, as defined by CCI scores, is not associated with neurological outcomes or survival in patients treated with TTM.
