Influence of Psychotropic Medications on Readmission Rates of Patients Receiving a Pharmacist Discharge Medication Reconciliation

Background: Current literature suggests that patients with psychiatric disorders are at an increased risk for inpatient readmission. This study evaluated the impact of pharmacist-driven discharge medication reconcilliation (DMR) on readmission rates of patients discharged with one or more psychotropic medications. Methods: This study was a retrospective review of patients receiving a pharmacist-driven DMR. The primary outcome was to compare the prevalence of 30-day readmission rates among patients who had a pharmacist DMR between patients who had at least one psychotropic medication upon discharge versus those without psychotropic medications. Secondary objectives were to (1) compare the number of medication discrepancies and pharmacist interventions prior to discharge and (2) compare prevalence of medical comorbidities between patients who had at least one psychotropic medication upon discharge versus those without psychotropic medications. Results: A total of 151 subjects were included who had a DMR and either at least one psychotropic medication at discharge (n = 69) or no psychotropic medications at discharge (n = 82). The 30-day readmission rates were similar between both groups ( P = .609). The mean number of discrepancies ( P < .001) and number of pharmacist interventions ( P = .005) were significantly greater in patients who had at least one psychotropic medication upon discharge compared to those without psychotropic medication. Conclusions: The prevalence of 30-day readmissions was similar between the two groups; however, patients discharged with at least one psychotropic medication had a greater number of discrepancies requiring significantly more discharge interventions during a pharmacist DMR.
