Application of the IHI Global Trigger Tool in measuring the adverse event rate in a Turkish healthcare setting

The goal of this study was to measure an adverse event rate and determine the potential usefulness of the Institute for Healthcare Improvement's Global Trigger Tool (GTT). Besides using the GTT to measure the adverse event rate, a comparison was also made with the internal Voluntary Reporting Notification System (VRNS) to identify and compare the strengths and weaknesses of the two approaches.

Retrospective data were collected from reported patient safety incidents covering a one-year period at Duzce University Hospital, Turkey. Using a range of selection criteria, a total of 219 patient records were selected and then reviewed by a trained GTT team, to investigate the positive triggers in the content of the patient records.

It was determined that adverse events per 1000 patient days totalled 80.72. Adverse events per 100 admissions were 29.39, and the rate of admissions with adverse events was 16.67%. The comparison between the GTT and the VRNS showed that the GTT is 19 times more sensitive than the VRNS in the adverse event evaluation process.

This is the first published study of the rate of adverse events in a Turkish healthcare setting using the GTT. It was found that the GTT was applicable in this setting, yielding more accurate measurement of the adverse event rate. However, the content of the GTT should be adjusted regarding the standards and documentations used in the Turkish healthcare system to be more useful.
