Physician compliance with advanced electronic alerts for preventing venous thromboembolism among hospitalized medical patients

Background: Worldwide, more than half of the hospitalized medical patients at high risk do not receive venous thromboembolism (VTE) prophylaxis. Although VTE among hospitalized patients at risk is reduced with electronic alerts (eAlerts), the majority of eAlerts are being ignored by the responsible physician. Methods: We investigated physician compliance with an advanced eAlert system in 1027 (age 59 ± 17 years) hospitalized medical patients. A continuously flashing non‐interruptive eAlert, visible to all healthcare professionals, was issued in the electronic patient chart 6 h after admission if the physician did not order prophylaxis. Results: The rate of appropriate prophylaxis increased from 44% before to 76% after the implementation of the eAlert system. Although the patients whose physicians cared for ≥ 20 patients during the study period had a more frequent physician response to the eAlert than patients whose physicians cared for fewer patients (69% vs. 40%, P
