Background: Hospitals routinely survey patients about the quality of care they receive, but little is known about whether patient interviews can detect adverse events that medical record reviews do not.
Objective: To compare adverse events reported in postdischarge patient interviews with adverse events detected by medical record review.
Design: Random sample survey.
Context: Hospitals are under pressure to increase revenue and lower costs, and at the same time, they face dramatic variation in clinical demand.
Objective: : We sought to determine the relationship between peak hospital workload and rates of adverse events (AEs).
Methods: A random sample of 24,676 adult patients discharged from the medical/surgical services at 4 US hospitals (2 urban and 2 suburban teaching hospitals) from October 2000 to September 2001 were screened using administrative data, leaving 6841 cases to be reviewed for the presence of AEs.
