Medical Adverse Event Review
Use when asked to structure, conduct, or write up an adverse event review — a structured investigation into a serious patient-safety event to identify contributing systemic factors — for general educational and structural guidance only, not medical advice; always follow institutional policy and consult the treating clinician or qualified health care professional for actual patient care decisions.

An adverse event review is a structured investigation into a serious patient-safety event, aimed at identifying the systemic factors that contributed to it and defining concrete changes to prevent recurrence. It goes beyond the initial factual capture to ask why the event was possible in the first place.
Key components
- Factual timeline — a reconstruction of what happened, built from medical records, monitoring data, medication records, and firsthand accounts from everyone involved, not from a single person's memory of the sequence.
- Contributing systemic factors — the conditions that made the event likely, examined across categories such as staffing levels, process design, communication and handoff, equipment, and the physical environment, not just the final visible action that preceded the event.
- Concrete corrective actions — specific changes, each with a named owner and a follow-up date, not just a list of findings. "Improve communication" is not a corrective action; "add a structured read-back step to the verbal order process by [date], owned by [name]" is.
- Follow-up verification — confirmation, at a defined later date, that each corrective action was actually implemented and is having the intended effect.
Why systemic factors matter more than the final visible error
The person who performed the last visible action before harm occurred is rarely the only, or even the most important, contributing factor. That person was usually operating inside conditions — short staffing, an ambiguous protocol, a missed handoff, a poorly designed form, alarm fatigue — that made the error more likely for anyone in that position. Stopping the review at "who did it" fixes nothing: the same conditions remain in place and will produce the same outcome again with a different person at the point of contact. Reviewing the systemic conditions is what actually changes the odds of recurrence.
How it relates to the incident report and the M&M conference
- vs. Medical Clinical Incident Report — the incident report is the prompt, factual capture of what happened, filed close to the event. The adverse event review is the deeper investigation that follows, focused on cause and systemic contributing factors.
- vs. Medical Morbidity and Mortality Review — an M&M review is typically a recurring peer-review conference format where cases are discussed. An adverse event review is the underlying investigation process itself, which may or may not later be presented at an M&M conference.
Common pitfalls
- Review stopping at the individual who made the final visible error — instead of examining the systemic conditions that made that error likely, the review ends with a name and a corrective note in a personnel file, and nothing about the underlying conditions changes.
- Findings with no tracked corrective action or follow-up — a review that identifies contributing factors but assigns no owner or date produces a document, not a change.
- Review conducted long after the event — the longer the delay, the more firsthand accounts degrade and the more the timeline depends on memory rather than records, weakening the review's conclusions.
- Treating the review as punitive — a review perceived as building a case against an individual discourages honest, detailed accounts from everyone involved, which is exactly what a systemic investigation depends on.
- Corrective actions never re-verified — assuming a recommended change was implemented, without checking, leaves the systemic gap open even after the review is formally closed.
