Abstract

Medication histories improve health care quality and safety; formularies serve to control costs. We describe the implementation of the Regenstrief Medication Hub: a system to provide both histories and formularies to the Gopher ePrescribing application. Currently the Medication Hub aggregates data from two sources: the RxHub consortium of pharmacy benefit managers, and Wishard Health Services. During one month, the system generated 53,764 queries, each representing a patient visit. RxHub responded with 4,012 histories; Wishard responded with 23,421 histories. The Medication Hub aggregated and filtered these histories before delivering them to Gopher. However, clinician users accessed the histories during only 0.6% of prescribing sessions. The Medication Hub also managed drug benefit eligibility data, which enabled formulary-based decision support. However, clinicians heeded only 41% of warnings based on the Wishard Formulary, and 16% of warnings based on commercial formularies. The Medication Hub is scalable to accommodate additional pharmacy data sources.
