Understanding harm


How harm occurs

"Adverse event" terminology


An adverse event refers to harm resulting from healthcare delivery [REF]
Canadian Patient Safety Institute, Disclosure Working Group. Canadian Disclosure Guidelines, 2008.
.

This includes harm from the recognized risks inherent in investigations or treatments, system failures, and sometimes problems in provider performance. Combinations of these factors may occur. While system failures contribute to many adverse events, the performance of a provider may also be a contributing factor in some adverse events.
