↵* Physician reviewers identified the clinical service responsible for patient care at the time that the adverse event occurred. For patients who experienced more than 1 adverse event, the most responsible clinical service may have differed for each or some of the adverse events. Therefore, results in this table are reported at the level of adverse events (n = 279) for the 237 patients who had 1 or more adverse events.
