||OBJECTIVE: This study explored the risk of patient safety events and associated nonfatal physical harms and mortality in a cohort of persons with serious mental illness. This group experiences high rates of medical comorbidity and premature mortality and may be at high risk of adverse patient safety events. METHODS: Medical record review was conducted for medical-surgical hospitalizations occurring during 1994-2004 in a community-based cohort of Maryland adults with serious mental illness. Individuals were eligible if they died within 30 days of a medical-surgical hospitalization and if they also had at least one prior medical-surgical hospitalization within five years of death. All admissions took place at Maryland general hospitals. A case-crossover analysis examined the relationships among patient safety events, physical harms, and elevated likelihood of death within 30 days of hospitalization. RESULTS: A total of 790 hospitalizations among 253 adults were reviewed. The mean number of patient safety events per hospitalization was 5.8, and the rate of physical harms was 142 per 100 hospitalizations. The odds of physical harm were elevated in hospitalizations in which 22 of the 34 patient safety events occurred (p<.05), including medical events (odds ratio [OR]=1.5, 95% confidence interval [CI]=1.3-1.7) and procedure-related events (OR=1.6, CI=1.2-2.0). Adjusted odds of death within 30 days of hospitalization were elevated for individuals with any patient safety event, compared with those with no event (OR=3.7, CI=1.4-10.3). CONCLUSIONS: Patient safety events were positively associated with physical harm and 30-day mortality in nonpsychiatric hospitalizations for persons with serious mental illness.
