Post-Hospital Discharge Care: A Retrospective Cohort Study Exploring the Value of Pharmacist-Enhanced Care and...

BACKGROUND Medication-related problems occur at high rates during care transitions. Evidence suggests that pharmacists are well-suited to identify and resolve medication-related problems during hospital admission and at discharge. Additional evidence is needed to understand the impact of face-to-face pharmacist visits in primary care after discharge. The purpose of the study was to describe medication-related problems found during face-to-face pharmacist visits in a medical home after hospital discharge.METHODS A retrospective cohort study was conducted within an academic primary care center staffed by family medicine trained physicians that evaluated patients who attended a hospital follow-up visit with pharmacist-enhanced care (N = 86) versus usual care (N = 86). The primary objective was to describe medication-related problems identified by pharmacists using a modified individualized Medication Assessment and Planning tool for patients receiving pharmacist-enhanced care. Secondary analyses were also conducted to compare 30-day and 60-day hospital readmission and emergency department visit rates in those exposed to pharmacist-enhanced care versus those who were not.RESULTS At baseline, the mean hospitalizations in the prior year were 1.1 ± 1.7 (pharmacist-enhanced care) and 0.76 ± 1.2 (usual care), indicating a low initial readmission risk. Of patients receiving pharmacist-enhanced care, 97.7% were found to have at least 1 medication-related problem, with an average of 4.36 medication-related problems per patient. The 30-day readmission rate was lower, but not significantly different between groups (8.1% for pharmacist-enhanced care versus 12.8% for usual care; adjusted odds ratio (OR), 0.47; 95% confidence interval (CI), 0.16-1.36).LIMITATIONS Limitations include the retrospective cohort study design and small sample size. Medication-related problems were identified and collected prospectively during pharmacist visits.CONCLUSION Medication-related problems are ubiquitous after hospital discharge. Larger prospective studies will be needed to understand the potential value of pharmacist-enhanced care during hospital follow-up visits on readmission rates in low-risk patient populations receiving care within a primary care medical home.
