Exploring the Utility of Automated Drug Alerts in Home Healthcare

Computerized drug utilization review (DUR) can potentially reduce adverse drug events. We examined automated DUR for home healthcare patients with diabetes or hypertension. Sixty-eight percent of diabetes patients and 50.7% of hypertension patients triggered severe, moderate, or duplicative alerts. Among diabetes patients, 74.3% of duplicative alerts were trivial or inappropriate, compared with 3.9% among hypertension patients. Experts judged that 40.5% of high-risk diabetes patients and 53.6% of hypertension patients had alerts requiring nurse follow-up. Adequate follow-up was significantly lower for the former. The relationship between inappropriate alerts and poorer follow-up reinforces the need for more specific alert systems to focus clinicians' attention on clinically important alerts.
