This study examined the impact of passive and active electronic medical record alerts on referrals to physical therapy and medication management for elderly patients at high risk of falls. The study found that a passive alert showing fall prevention resources had little impact on physical therapy referrals. However, an active alert identifying high-risk medications was associated with increased response to the passive alert and led to more medication reviews and discontinuations. The results suggest that active alerts may be more effective than passive alerts at prompting clinician action to address fall risk factors.
