Application Status of Global Trigger Tool / 医药导报

ABSTRACT

Objective To understand the current application status of global trigger tool ( GTT) in China and abroad, and to provide reference for application and improvement of GTT in medical institutes in China. Methods The databases of Pubmed and CNKI were searched, and the relevant literatures were reviewed and collected, and the application of GTT for measuring adverse events ( AE ) were analyzed and evaluated. Results Fifty-eight valid articles from 15 countries were included.The studies involve several aspects of GTT applications. Articles about GTT used for measuring the incidence of AE accounted for 62.07%, the researches on the object category of AE accounted for 36.21%, those evaluating the effectiveness of GTT as an AE measurement tool accounted for 27.59%, those about improvement and exploration of GTT application performance accounted for 23. 41%, and those about comparison between GTT and other AE detection methods accounted for 15. 52%. In 18.97% of the studies, the number of reviewers and criteria were accordant with the GTT White Paper, but 32.76% of the studies did not clearly describe the reviewers and criteria. The most common method for reporting the AE rate was the proportion of patients with AE.The research object includes 11 categories:common hospital patients, children, patients in intensive care unit ( ICU) , etc.; AE ratio of common hospital patients was 3. 4% to 43. 3%, the preventable proportion was between 32. 2% and 72.4%.The most common types of AE were drug related adverse events, infection/hospital acquired infections, surgery-related complications, abnormal blood potassium, pressure ulcer and so on. Evaluation performed in the United States, Republic ofKorea, Spain, China and other countries and regions' showed GTT had higher efficiency and other advantages as compared with the other AE detection methods including voluntary reporting system, HMPS, QPSIQ DLCR.The exploration of GTT performance improvement involves many factors influencing the detection effectiveness such as different reviewers, review experience, sampling method, sample size, trigger etc. Conclusion GTT has been applied to AE detection of hospital patients in various countries, and it has shown some advantages. GTT is an effective tool for AE measuring, which could be widely used in AE monitoring of hospitalized patients in medical institutions of China.
