Introduction Medication safety challenges are common after hospital discharge and an important global health care improvement target [1,2]. ‘Transfers of Care Around Medicines’ (TCAM) services have been suggested as an intervention that may help address this problem, and are designed to enable the referral of patients on discharge from the hospital to a named community pharmacy in the surrounding Clinical Commissioning Group (CCG). A TCAM service was launched by a large NHS Trust in England in February 2019 to enhance medicines communication and optimisation between primary and secondary care following hospital discharge. The TCAM service is delivered through the PharmOutcomes™ platform, and the initial focus of the service was to support patients with new or existing Monitored Dosage Systems (MDS). Aim To evaluate the utilisation of the TCAM service in the host NHS Trust and surrounding CCG through the examination of the nature and outcome of referrals made to community pharmacy. Method Anonymised service delivery data of patients referred from the TCAM service via the PharmOutcomes™ platform between March 2019 – February 2020 were retrospectively examined. The data comprised important variables, including patient demographics, status and time of referrals, and referral outcomes including problems/errors identified with medications and services provided by the community pharmacy such as medicines reconciliation. Study approvals were obtained from the host NHS Trust and the Health Research Authority (HRA); the study was exempt from the University Research Ethics Committee (UREC) approval [2019-7048-10983]. Results A total of 3,033 TCAM referrals to 67 community pharmacies were analysed. Most referrals were for patients aged 70 and above (72%, n=2,195) and 56% (n=1,713/3,033) of the referrals were for female patients. The number of referrals varied between 215 and 310 per month (median 246, Inter quartile range [IQR] 234 - 268). Most referrals (67%, 2,038/3,033) were marked as ‘completed’ by the community pharmacies, with 32.8% (n=995) left uncompleted. The rate of referral completion varied between 59 and 80% per month (median 66.4, IQR 64.5 - 70). Five (0.2%) patients were identified by community pharmacies that had adverse drug reactions (ADRs) from the cohort of 2,038 patients with completed referrals, with 45 (2%, n=45/2,038) identified as having issues that necessitated referral to the general practitioner (GP). The most common reason for referral to GP was medication changes identified from hospital, incorrect repeat prescriptions following discharge, to request a new prescription or weekly MDS, and to inform the GP that the patient has stopped taking their medication. The most common services carried out in community pharmacies following referral were reported as medicines reconciliation (47%, n=954/2,038), followed by review of information (46.7%, n=952/2,038), home delivery of medication (39%, n=798/2,038), review MDS arrangements (23.6%, n=482/2,038), commence MDS (18.6%, n=380/2,038), and pharmacy managed repeat service (12%, n=254/2,038). The main strength of this study is the inclusion of referral data that occurred over a one-year period, while the data were limited in generalisability due to inclusion of one geographical region and only patients using MDS. Conclusion The findings of this study may inform the ongoing development of electronic pharmacy referral systems for use at hospital discharge. References 1. Alqenae FA, Steinke D, Keers RN.
