Impact of CancelRx on Discontinuation of Controlled Substance Prescriptions

Abstract

ObjectiveTo assess how controlled substance medication discontinuations were communicated over timeData SourcesSecondary data from a midwestern academic health system electronic health record and pharmacy platform were collected 12-months prior to CancelRx implementation and for 12-months post implementation.Study DesignThe study utilized an interrupted time series analysis (ITSA) to capture the proportion of controlled substance medications that were cancelled in the clinic’s electronic health record and also cancelled in the pharmacy’s dispensing software. The ITSA plotted the proportion of successful cancellation messages over time, particularly after the health system’s implementation of CancelRx, a novel technology.Data Collection/ExtractionData were extracted from the EHR and pharmacy records for patients aged 18+ who had a controlled substance discontinued by a health system provider. Information collected included patient demographics, drug information (name, dose), and dates discontinued in the clinic and pharmacy records.Principal FindingsAfter CancelRx implementation there was a significant increase in the proportion of discontinued controlled substance medications that were communicated to the pharmacy.ConclusionsThis study demonstrates the role that technology can play in promoting controlled substance policy and medication safety.
