Root cause analysis is a tool that can be used when determining how and why a patient safety incident has occurred. Incidents that usually require a root cause analysis include the unexpected death of a patient, serious pressure ulcers, falls that result in injury, and some infections and medication errors. This article outlines the stages of the investigation process for undertaking a root cause analysis.
Root causes are the fundamental issues that led to the occurrence of an incident and can be identified using a systematic approach to investigation. Contributory factors related to the incident may also be identified.
Crucial questions in a root cause analysis are: what happened? How did it happen? And why did it happen?
Undertaking a root cause analysis can assist in identifying areas for change and developing recommendations, with the aim of providing safe patient care.
