IHI Global Trigger Tool for Measuring Adverse Events (Second Edition)

The IHI Global Trigger Tool for Measuring Adverse Events provides an easy-to-use method for accurately identifying adverse events (harm) and measuring the rate of adverse events over time. Tracking adverse events over time is a useful way to tell if changes being made are improving the safety of the care processes.

The Trigger Tool methodology includes a retrospective review of a random sample of patient records using “triggers” (or clues) to identify possible adverse events. Many hospitals have used this tool to identify adverse events, to measure the level of harm from each adverse event, and to identify areas for improvement in their organizations. It is important to note, however, that the IHI Global Trigger Tool is not meant to identify every single adverse event in a patient record.
The recommended time limitation for review and the random selection of records are designed to produce a sampling approach that is sufficient for the design of safety work in the hospital.
This toolkit is available in a PDF format (requiring Adobe Reader) through the IHI website after a free registration.
