Impacting Readmission Rates and Patient Satisfaction: Results of a Discharge Pharmacist Pilot Program

Background Readmission to a hospital within 30 days of discharge has become a key quality outcome measure. With an observed 30-day readmission rate as high as 20% and attributed costs of almost $17.4 billion a year for Medicare patients, the potential implications for patients and the entire health care system are significant. Medication-related complications have been shown to increase the risk for unplanned readmission. Pharmacists have an opportunity to impact quality and cost by risk stratifying and identify patients at high risk for hospital readmission. Objective To study the impact of a pharmacist-driven discharge counseling program for high-risk patients identified by BOOST (Better Outcomes for Older adults through Safe Transitions) criteria on 30-day readmission rates. Method This was a prospective, cohort, nonrandomized trial at a single medical-surgical unit with telemetry capability at a single academic medical center including 669 patients who were older than 18 years. Primary outcome was 30-day readmission rate. Secondary outcomes were the number and type of pharmacist interventions, cost avoidance, and patient satisfaction results. Results The readmission rate for patients counseled by a pharmacist during the discharge process was 15.7% compared to 21.6% for patients not counseled by a pharmacist on discharge (relative risk [RR] 0.728; 95% confidence interval [CI], 0.514–1.032; P = .04). The readmission rate for adult medicine patients not counseled at discharge by a pharmacist in the study was comparable to the readmission rates of a similar patient control group at 3 months and 1 year prior to the initiation of the study (18.7% and 19.1% vs 19.6%). Conclusions Pharmacists' support in the discharge process facilitated increased communication on the multidisciplinary team and resulted in a lower unplanned readmission rate for patients.
