Objective Medication list discrepancies between outpatient clinics and pharmacies can lead to medication errors. Within the last decade, a new health information technology (IT), CancelRx, emerged to send a medication cancellation message from the clinic’s electronic health record (EHR) to the outpatient pharmacy’s software. The objective of this study was to measure the impact of CancelRx on reducing medication discrepancies between the EHR and pharmacy dispensing software. Materials and Methods CancelRx was implemented in October 2017 at an academic health system. For 12 months prior, and 12 months after CancelRx implementation, data were collected on discontinued medications in the health system’s EHR and whether those prescriptions were successfully discontinued in the pharmacy’s dispensing software. An interrupted time series analysis was conducted to model the occurrence of prescriptions successfully discontinued over time. Results There was an immediate (lag = 0), significant (P < 0.001), and sustained (post-implementation slope 0.02) increase in the proportion of successful medication discontinuations after CancelRx implementation (from 34% to 93%). CancelRx had variable impact based on whether the clinic was primary care (71.4% change prepost) or specialty care (53.9% change prepost). CancelRx reduced the time between when a medication was discontinued in the clinic EHR and pharmacy dispensing software. Conclusion CancelRx automated a manual process and illustrated the role for health IT in communicating medication discontinuations between clinics and pharmacies. Overall, CancelRx had a marked benefit on medication list discrepancies and illustrated how health IT can be used across different settings to improve patient care.

ObjectivesThis study aimed to evaluate the impact of electronic communication of medication discontinuation from prescribers to pharmacies (CancelRx) on medication safety.MethodsWe used electronic health record (EHR) data to identify medications that were e-prescribed from a pilot practice to a health system pharmacy and subsequently discontinued before or after CancelRx implementation (January 16–April 15, 2018 versus 2019). We matched these EHR data to pharmacy management software data to identify medications that were sold to patients in the 6 months after discontinuation. As a surrogate for unintended cancellation, we also identified medications refilled within 120 days of discontinuation. We conducted a medical record review to identify documentation of prescriber intent to discontinue these medications.ResultsCancelRx implementation prevented prescriptions from being sold after discontinuation in the EHR (42 of 392 [10.7%] versus 0 of 387 [0.0%], P < 0.0001), but only 15 of 42 (35.7%) had documented intent to discontinue the medication (15 of 392, or 3.8% overall). There was a nonsignificant increase in the proportion of discontinued medications reordered within 120 days (10.0% versus 12.7%, P = 0.23). Medical record review of reordered prescriptions after CancelRx implementation found that 10 of 49 (10 of 387, or 2.6% overall) might have been unintentionally canceled.ConclusionsImplementation of CancelRx eliminated the sale of e-prescribed medications after discontinuation in the EHR but might result in the unintentional cancellation of some prescriptions. Strategies to increase situational awareness of providers and pharmacy staff, including increased visibility of CancelRx, clear distinctions between active and expired prescriptions, and transmission of the reason for discontinuation, might reduce the risk of unintentional cancellations.

Analysis of patient records found most patients did not have an indication listed in the EHR problem list that would match a specific medication, suggesting that the problem lists may be incomplete. When using MEDI, 61% of prescriptions matched to the problem list, compared with only 38% using MEDI-HPS. Likewise, 37% of problems matched to prescriptions when using MEDI, compared with only 21% using MEDI-HPS.

Background Prescription opioid misuse is a serious national crisis; in 2018 the top drugs involved in prescription overdose deaths included pain medications (opioids), benzodiazepines, and stimulants. Health information technology (health IT) provides a means to address this crisis through technologies that streamline the prescribing and discontinuation process. CancelRx is a health IT function that communicates when medications, such as controlled substances, are discontinued at the clinic and therefore should not be filled at the pharmacy. Prior to CancelRx, the communication of discontinued medications was a manual process, requiring the patient or a clinic staff member to personally contact the pharmacy to inform them of the change. The objective of this study was to assess how controlled substance medication discontinuations were communicated over time, before and after the implementation of CancelRx. Methods Secondary 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. The study utilized an interrupted time series analysis (ITSA) to capture the percentage of controlled substance medications that were discontinued in the clinic’s electronic health record and discontinued in the pharmacy’s dispensing software. The ITSA plotted the percentage of successful discontinuation messages over time, particularly after the health system’s implementation of CancelRx, a novel technology. Results After CancelRx implementation there was an immediate (change = 77.7 percentage point) and significant (p < 0.001) increase in the number of controlled substance medications that were successfully discontinued at the pharmacy after being discontinued in the clinic. This change was sustained in the year following CancelRx (slope = 0.03 pp, 95% CI − 0.050 to 0.110) and did not revert to pre-CancelRx levels. The health IT functionality was able to effectively complete discontinuation tasks and potentially reduce workload for clinic staff. Conclusions Overall, this study demonstrates the role that technology can play in promoting communication between clinics and pharmacies, especially when medications such as controlled substances are discontinued.
