ObjectivesThe primary objective of this study was to determine whether pharmacist‐clinician collaborative (PCC) visits within 7 days after hospital discharge (early‐visit cohort) would reduce the risk of 30‐day hospital readmission compared with PCC visits eight or more days after hospital discharge (late‐visit cohort).MethodsThis retrospective study of adult primary care patients was conducted from July 26, 2013 to April 1, 2016. Patients who were included were receiving at least one medication that put them at high risk for emergent hospital admission and at least 10 total medications. A Cox proportional hazards model was used to assess 30‐day readmission risk between the two groups.ResultsThe early‐visit cohort included 393 patients; the late‐visit cohort included 109 patients. After adjusting for statistically different baseline characteristics and the LACE index score (which predicts the risk of death or unplanned readmission within 30 days after hospital discharge), 30‐day readmission risk was not significantly different between the late‐visit cohort and the early‐visit cohort (hazard ratio, 0.8; 95% confidence interval [CI], 0.34‐1.88; P = 0.61). Similarly, the difference was not significant 60 and 180 days after the PCC visit.ConclusionPatients in the early‐visit cohort had no greater risk of readmission 30 days after the visit than patients in the late‐visit cohort. Although previous research indicates that PCC visits may have significant benefits for decreasing readmission risk, delaying them may not increase the patient's risk. This finding may allow more flexibility in scheduling a pharmacist and a primary care clinician to meet with the patient.
