Impact of clinical decision support therapeutic interchanges on hospital discharge medication omissions and duplications

PURPOSE

Automatic therapeutic substitution (ATS) protocols are formulary tools that allow for provider-selected interchange from a nonformulary preadmission medication to a formulary equivalent. Previous studies have demonstrated that the application of clinical decision support (CDS) tools to ATS can decrease ATS errors at admission, but there are limited data describing the impact of CDS on discharge errors. The objective of this study was to describe the impact of CDS-supported interchanges on discharge prescription duplications or omissions.

METHODS

This was a single-center, retrospective cohort study conducted at an academic medical center. Patients admitted between June 2017 and August 2019 were included if they were 18 years or older at admission, underwent an ATS protocol-approved interchange for 1 of the 9 included medication classes, and had a completed discharge medication reconciliation. The primary outcome was difference in incidence of therapeutic duplication or omission at discharge between the periods before and after CDS implementation.

RESULTS

A total of 737 preimplementation encounters and 733 postimplementation encounters were included. CDS did not significantly decrease the incidence of discharge duplications or omissions (12.1% vs 11.2%; 95% confidence interval [CI], -2.3% to 4.2%) nor the incidence of admission duplication or inappropriate reconciliation (21.4% vs 20.7%; 95% CI, -3.4% to 4.8%) when comparing the pre- and postimplementation periods. Inappropriate reconciliation was the primary cause of discharge medication errors for both groups.

CONCLUSION

CDS implementation was not associated with a decrease in discharge omissions, duplications, or inappropriate reconciliation. Findings highlight the need for thoughtful medication reconciliation at the point of discharge.

Strategies for success in creating an effective multihospital health-system pharmacy and therapeutics committee

PURPOSE

Lessons learned from the creation of a multihospital health-system formulary management and pharmacy and therapeutics (P&T) committee are described.

SUMMARY

A health system can create and implement a multihospital system formulary and P&T committee to provide evidence-based medications for ideal healthcare. The formulary and P&T process should be multidisciplinary and include adequate representation from system hospitals. The aim of a system formulary and P&T committee is standardization; however, the system should allow flexibility for differences. Key points for a successful multihospital system formulary and P&T committee are patience, collaboration, resilience, and communication. When establishing a multihospital health-system formulary and P&T committee, the needs of individual hospitals are crucial. A designated member of the pharmacy department needs to centrally coordinate and manage formulary requests, medication reviews and monographs, meeting agendas and minutes, and a summary of decisions for implementation. It is imperative to create a timeline for formulary reviews to set expectations, as well as a process for formulary appeals. Collaboration across the various hospitals is critical for successful formulary standardization. When implementing a health-system P&T committee or standardizing a formulary system, it is important to be patient and give local sites time to make practice changes. Evidence-based data and rationale must be provided to all sites to support formulary changes. Finally, there must be multidisciplinary collaboration.

CONCLUSION

There are several options for formulary structures and P&T committees in a health system. Potential strengths and barriers should be evaluated before selecting a formulary management process.
