Factors influencing outcome of MCA remain largely unexplored. We sought to further elucidate the factors affecting maternal death from in-hospital MCA. STUDY DESIGN: Our query of the American Heart Association’s Get with the Guidelines Resuscitation voluntary registry from 2000-2016 revealed 462 index cases of MCA. Utilizing characteristics identified from our descriptive analysis, we performed a stepwise logistic regression comparing those with hospital death to survivors from our MCA cohort. Elements in the model included: age, race, year of arrest, first documented pulseless rhythm, pre-existing conditions, location of arrest and hospital characteristics. This study was determined to be exempt according to institutional review board standards. RESULTS: Of the 462 cases of MCA, hospital death occurred in 59.3%. Hospital characteristics including rural versus urban, bed size or ownership did not appear to influence MCA outcome in this cohort. Hospital death from MCA appeared to be associated with pre-existing renal insufficiency (OR 1⁄4 3.021 p1⁄4 0.052) and
