IHI Trigger Tool

The Institute for Healthcare Improvement's (IHI)
Global Trigger Tool
for Measuring Patient Safety

The use of "triggers," or clues, to identify adverse events (AEs) is an effective method for measuring the overall level of harm in a health care organization. The IHI Global Trigger Tool for Measuring AEs provides instructions for training reviewers in this methodology and conducting a retrospective review of patient records using triggers to identify possible AEs. This tool includes a list of known AE triggers as well as instructions for selecting records, training information, and appendices with references and common questions.
