1285 implementation of a medicine management plan to reduce medication-related harm in older people post-hospital discharge - an rct

Abstract Introduction Medication-related harm (MRH) events are increasing among older adults especially in the 8-weeks after hospital discharge. The Discharge Medical Service (DMS), a UK initiative, aims to reduce post-discharge MRH. In this study, we will compare the clinical, economic, and service outcomes of the DMS. Method Using a randomised control trial design, 682 older adults ≥ 65years due for hospital-discharge will be recruited. Participants will be randomized to either intervention arm (medicine management plan (MMP) and DMS), or control arm (DMS only) using a 1:1 stratification. The MMP includes patient and carer education about MRH, copy of discharge medications, and MRH risk score calculated using a validated prediction tool (1). Data collection includes patient clinical and social demographics, and admission and discharge medications. At 8-weeks post discharge, study pharmacist will verify MRH through patient telephone interview, and review of patients’ GP records. Data Analysis Univariate analysis will be done for baseline variables comparing the intervention and control arms. Variables known to be associated with MRH will be described by the randomisation groups. Further multivariate logistic regression will be done incorporating these variables. Economic evaluation will compare the cost-of-service use among the two arms and modelled to provide national estimates. Qualitative data from focus group interviews at participating hospital sites will explore practitioners’ understanding and acceptance of the DMS and MMP. Conclusion This study will inform the use of a validated MRH risk prediction tool, and provide a clinical, and economic evaluation of the DMS and MMP in the NHS. The study has ethics approval and is adopted in the national ageing research portfolio. We are seeking additional sites. Reference 1. Parekh N, Ali K, Davies JG et al.
