摘要

Background

Anticoagulation therapy presents a high risk of adverse drug events (ADEs) in hospitalized patients, highlighting the need for effective detection strategies in clinical practice.

Aim

The review aimed to identify triggers for detecting anticoagulation-associated ADEs in hospitalized patients and describe the performance of these triggers.

Method

PubMed, Cochrane, and Embase were queried until April 19, 2024. We included studies on trigger tools for detecting anticoagulation-related ADEs in hospitalized patients. The study quality was assessed using the Quality Assessment Trigger framework based on the QUADAS-2 tool for diagnostic accuracy. We performed random-effects meta-analyses to pool positive predictive values (PPV), with heterogeneity assessed via I2 statistic and Cochran’s Q test.

Results

Twenty-three studies were included. Seventeen triggers were reported and categorized into three modules: abnormal laboratory values (11 triggers), medications or antidotes (three triggers), and care (three triggers). Elevated international normalized ratio (INR) was the most prevalent trigger (16 studies) with a PPV of 0.539 (95% Confidence Interval [CI] 0.310–0.768). Other triggers exhibited lower pooled PPVs than elevated INR, including vitamin K administration (15 studies, PPV 0.222, 95% CI 0.153–0.290), abrupt medication cessation (14 studies, PPV 0.418, 95% CI 0.169–0.667), and activated partial thromboplastin time > 100 s (11 studies, PPV 0.336, 95% CI 0.173–0.498). Importantly, in-hospital stroke (three studies) had the highest pooled PPV of 0.964 (95% CI 0.803–1.000).

Conclusion

This review demonstrated the variability in PPVs of triggers for anticoagulation-associated ADEs, emphasizing the necessity for a specialized trigger tool for hospitalized patients on anticoagulants.
