Objective: To evaluate the impact of a post-discharge pharmacist telephone call on 30- and 90- day readmission rates as part of a transitional care management (TCM) service in a geriatric patient-centered medical home (PCMH).
Methods: Adults 60 years of age and older who had established primary care at the PCMH for at least one year and were discharged from the hospital between 7/1/2013 and 2/21/2016 were included. Readmission rates for patients who received and did not receive a pharmacist TCM phone call were compared. Secondary data analysis was conducted between individuals who received all three components of the service compared with those who received on a nurse navigator plus primary care provider (PCP) visit.
Results: Among 513 discharges of unique patients (mean age, 80.4 years; women 63%), 269 (52.4%) received a pharmacist phone call. Readmission rates at 30 days were 8.9% for patients who received a pharmacist TCM phone call compared to 12.7% for those who did not receive this service (OR 0.67 [95% CI, 0.38-1.18; P=0.17]). When comparing only those individuals who received all three components of the service (pharmacist, nurse navigator, and PCP) (n=215) compared to those who received only a nurse navigator plus PCP visit (n=66), there was no difference in 30-day readmission rates (7.9% vs. 10.6%, p=0.49). However, there were significantly fewer readmissions within 90-days (16.3% vs. 31.8%, p=0.01).
Conclusion: Pharmacist phone calls as part of an interdisciplinary TCM service did not result in a statistically significant difference regarding readmission rates at 30 days; however, patients who received all three components of the service had significantly fewer readmissions at 90 days, compared to patients who did not speak with a pharmacist but did complete a visit with a nurse navigator and physician. Future research is needed to determine which patients may benefit the most from this service and to identify strategies to increase patient participation.
