Background. Recent studies of risks in cardiopulmonary arrest (CPA) have been performed using large databases from a broad mix of hospital settings. However, these risks might be different in a large, urban, academic medical center. We attempted to validate factors influencing outcomes from CPA at the University of Maryland Medical Center (UMMC). Methods. Retrospective chart review of all adult patients who underwent CPA between 2000 and 2005 at UMMC. Risk factors and outcomes were analyzed with appropriate statistical analysis and compared with published results. Results. 729 episodes of CPA were examined during the study period. Surgical patients had better survival than medical or cardiac patients. Intensive care unit' (ICU) patients had poor survival, but there was no difference on monitored or unmonitored floors. Respiratory etiologies survived better than cardiac etiologies. CPR duration and obesity were negatively correlated with outcome, while neurologic disease, trauma, and electrolyte imbalances improved survival. Age, gender, race, presence of a witness, presence of a monitor, comorbidities, or time of day of CPA did not influence survival, although age was associated with differences in comorbidities. Conclusions. UMMC risk factors for CPA survival differed from those in more broad-based studies. Care should be used when applying the results of database studies to specific medical institutions.
