The Impact of Real-Time Documentation of In-Hospital Medication Changes on Preventing Undocumented Discrepancies at Discharge and Improving Physician-Pharmacist Communication: A Retrospective Cohort Study and Survey.

Background: Transitional medication safety is crucial, as miscommunication about medication changes can lead to significant risks. Unclear or incomplete documentation during care transitions can result in outdated or incorrect medication lists at discharge, potentially causing medication errors, adverse drug events, and inadequate patient education. These issues are exacerbated by extended hospital stays and multiple care events, making accurate medication recall challenging at discharge. Objective: Thus, we aimed to investigate how real-time documentation of in-hospital medication changes prevents undocumented medication changes at discharge and improves physician-pharmacist communication. Methods: We conducted a retrospective cohort study in a tertiary hospital. Two pharmacists reviewed medical records of patients admitted to the acute medical unit from April to June 2020. In-hospital medication discrepancies were determined by comparing preadmission and hospitalization medication lists and it was verified whether the physician's intent of medication changes was clarified by documentation. By a documentation rate of medication changes of 100% and <100%, respectively, fully documented (FD) and partially documented (PD) groups were defined. Any undocumented medication changes at discharge were considered a "documentation error at discharge". Pharmacists' survey was conducted to assess the impact of appropriate documentation on the pharmacists. Results: After reviewing 400 medication records, patients were categorized into FD (61.3%) and PD (38.8%) groups. Documentation errors at discharge were significantly higher in the PD than in the FD group. Factors associated with documentation errors at discharge included belonging to the PD group, discharge from a non-hospitalist-managed ward, and having three or more intentional discrepancies. Pharmacists showed favorable attitudes towards physician's documentation. Conclusion: Appropriate documentation of in-hospital medication changes, facilitated by free-text communication, significantly decreased documentation errors at discharge. This analysis underlines the importance of communication between pharmacists and hospitalists in improving patient safety during transitions of care.

During transitions of care, communication failures among healthcare professionals can lead to medication errors. Therefore, effective sharing of information is essential, especially when intentional changes in prescription orders are made. Documenting medication changes facilitates real-time communication, potentially improving medication reconciliation and reducing discrepancies. However, inadequate documentation of medication changes is common in clinical practice. This retrospective cohort study underlines the importance of real-time documentation of in-hospital medication changes. There was a significant reduction in documentation errors at discharge in fully documented group, where real-time documentation of medication changes was more prevalent. Pharmacists showed favorable attitudes toward the physician's real-time documenting of medication changes because it provided valuable information on understanding the physician's intent and improving communication and also saved time for pharmacists. This study concludes that physicians' documentation on medication changes may reduce documentation errors at discharge, meaning that proper documentation of medication changes could enhance patient safety through effective communication.

Clinical and economic impact of medication reconciliation by designated ward pharmacists in a hospitalist-managed acute medical unit.

BACKGROUND: Minimizing unintended medication errors after admission is a common goal for clinical pharmacists and hospitalists. OBJECTIVE: We assessed the clinical and economic impact of a medication reconciliation service in a model of designated ward pharmacists working in a hospitalist-managed acute medical unit as part of a multidisciplinary team. METHODS: In this retrospective observational study, we compared pharmacist intervention records before and after the implementation of a medication reconciliation service by designated pharmacists. The frequency and type of intervention were assessed and their clinical impact was estimated according to the length of hospital stay and 30-day readmission rate. A cost analysis was performed using the average hourly salary of a pharmacist, cost of interventions (time spent on interventions), and cost avoidance (avoided costs generated by interventions). RESULTS: After the implementation of the medication reconciliation service, the frequency of pharmacist interventions increased from 3.9% to 22.1% (p < 0.001). Intervention types were also more diverse than those before the implementation. The most common interventions included identifying medication discrepancies between pre-admission and hospitalization (22.7%) and potentially inappropriate medication use in the elderly (13.1%). The median length of hospital stay decreased from 9.6 to 8.9 days (p = 0.024); the 30-day readmission rate declined significantly from 7.8% to 4.8% (p = 0.046). Over two-thirds of interventions accepted by hospitalists were considered clinically significant or greater in severity. The cost difference between avoided cost and cost of interventions was 9838.58 USD in total or 1967.72 USD per month. CONCLUSIONS: The implementation of a designated pharmacist-led medication reconciliation service had a positive clinical and economic impact in our hospitalist unit.
