Abstract

Medical applications frequently contain a wide range of functionalities. Users are often unaware of all of the functionalities available. More effective ways of delivering information about available functionalities to the users are needed. We conducted a pseudo-randomized controlled trial to determine whether interruptive alerts will increase utilization of several functionalities by the users of the Pre-Admission Medication List (PAML) Builder application at two academic medical centers. In a log-linear model, alerts increased total utilization of the promoted functionalities per PAML built by 70% compared to the controls at the site level (p
