An After Action Review (AAR) is a qualitative review of actions taken in response to an event of public health concern. It is a means of identifying and documenting best practices and challenges demonstrated by the response to the event.
An AAR seeks to identify:
- Corrective actions that need to be implemented immediately, to ensure better preparation for and response to the next event;
- Medium- and long-term actions needed to strengthen and institutionalize the necessary capabilities of the public health system.
It relies primarily on personal experiences and perceptions of any individuals or entities involved in the response. The process involves a structured facilitated discussion or experience sharing to critically and systematically review what was in place before the response, what happened during the response, what went well, what went less well, why events occurred as they did, and how to improve.
