Effect of Pharmacist Interventions on Hospital Readmissions for Home-Based Primary Care Veterans

Several studies indicate that when patients transition from one level of care to another, errors may occur. Pharmacists can play an integral role in the transitions of care process. At Michael E. DeBakey Veteran Affairs Medical Center, the Home-Based Primary Care (HBPC) service has implemented a streamlined hospital discharge plan to improve 30-day readmission rates after 1 year of HBPC enrollment.

Our aim was to identify specific pharmacist interventions to improve the HBPC discharge process and ultimately, improve hospital readmission rates. A Plan-Do-Study-Act quality improvement project was initiated. We conducted a review of veterans enrolled in HBPC from October 2019 to March 2020.

Of 175 patients assessed postdischarge, a medication reconciliation was completed by an HBPC pharmacist in 118 (67.4%) patients. Of the 118 medication reconciliations completed, 92 (78%) interventions were made by HBPC pharmacists. During the 6-month study period, 30-day hospital readmission rates decreased from 19% to 13%.

This study demonstrates several opportunities for interventions to lower readmission rates. Using the results from this study, education has been provided for the HBPC service and its readmission committee.
