Implementation of a Pharmacist-Managed Transitions of Care Tool
Purpose: To improve, expand, and sustain a pharmacist-based transitions of care (TOC) program and to assess interventions targeting veterans at high risk for adverse outcomes.
Methods: A TOC program was developed and piloted at the Richard L. Roudebush Veterans Affairs Medical Center (RLRVAMC). Following success of the pilot project, targeted interventions were identified to improve and expand the program. Patients deemed high risk for readmission by an acute care pharmacist were identified and referred for continued postdischarge follow-up. The study population included patients discharged to the community with primary care established within the RLRVAMC system. Eligible patients were entered into a TOC database by the referring acute care pharmacist. A pharmacist in the primary care clinic reviewed then contacted the patient within 1 week of discharge. Appropriate documentation of each visit was completed in the electronic health record. Data collection included background information, time to follow-up, medication discrepancies, pharmacist interventions, emergency department visits, and hospital readmissions.
Results: A total of 139 patients were included, of which 99 patients were reached for pharmacist follow-up. There were 43 medication-related discrepancies among all patients. The most common discrepancy was taking the wrong dose of a prescribed medication. Additional counseling was provided to 75% of patients. The subset of patients who were reached by a pharmacist had decreased index (5.1% vs 15.0%; P = .049) and all-cause readmissions (8.1% vs 27.5%; P = .03) at 30 days compared with those who did not received pharmacist follow-up, respectively.
Conclusions: This study demonstrated that implementation and expansion of a pharmacist-based TOC process is effective in communicating high-risk patients and intervening on medication-related issues postdischarge.
Limitations
There are some limitations identified within this study. Although the referral criteria were relaxed from the pilot study and enhanced education was created, continued education regarding appropriate referral of TOC patients continues to be necessary given intermittent staff changeover, incorporation of pharmacy trainees, and modifications to clinic workflow. Patients who were discharged to facilities were not included. This ensured that appropriate and consistent PACT pharmacist follow-up would be available, but likely reduced our sample size.
Although performing this study in a closed health care system with pharmacists who have independent SOPs is a strength of our study, also it can limit generalizability. Not all facilities house both acute care and ambulatory care in one location with wide SOPs to allow for comprehensive and continued care. Last, this study used convenience sampling, potentially introducing selection bias, as patients unable to be reached by PACT pharmacists may inherently be at increased risk for hospital readmission. However, in the 3 months preceding the hospital admission that resulted in TOC tool referral, both groups had a similar number of patients with hospital admissions and ED visits.
The TOC tool has become fully integrated into the daily workflow for both acute care and PACT pharmacists. After the conclusion of the study period, the referral rates into the tool have been maintained at a steady level, even surpassing the rates seen during the study period. In comparison with the pilot study, PACT pharmacists reported a subjective increase in referrals placed for procedures such as medication reconciliation or adherence checks. This is likely because acute care pharmacists were able to use their clinical judgement rather than to rely solely on calculated readmission risk scores for TOC tool referral.
The success of the TOC program led to the expansion to other specialty areas. ED pharmacists now refer patients from the ED who were not admitted to the hospital but would benefit from PACT follow-up. Additionally, the option to refer hematology and oncology patients was added to allow these patients to be followed up by our hematology/oncology CPSs by phone appointments. Unique reasons for follow-up for this patient population include concerns about delayed chemotherapy cycles or chemotherapy-associated AEs.
Conclusions
This study outlines the creation and continued improvement of a pharmacist-based TOC program. The program was designed as a method of communication between acute care and PACT pharmacists about high-risk patients. The creation of this program allowed PACT pharmacists not only to identify discrepancies and make interventions on high-risk patients, but also demonstrate that having pharmacists involved in these programs may have a positive impact on readmissions and ED visits. The success of the TOC tool at the RLRVAMC has led to its expansion and is now an integral part of the daily workflow for both acute care and PACT pharmacists.
