3036 Evaluation of a new regional pathway for Medicines Optimisation in Older People (MOOP) medicines adherence pharmacist optimising

Abstract Introduction The Regional Medicines Optimisation in Older People (MOOP) Medicines Adherence Pharmacy team review medicines for older people at home across Northern Ireland (NI). Northern Ireland Ambulance Service (NIAS) are often first responders to older people at home requiring medical attention, and identify medicines adherence issues, which may lead to Emergency Department presentation and hospitalisation if not addressed. Method In July 2023, Belfast HSC Trust MOOP pharmacy team led a new regional pathway pilot to enable NIAS first responders to refer older people for medicines adherence review. Inclusion Criteria: Pharmacist Interventions were graded using Eadon grading scale (1), & ScHARR cost avoidance estimates (2,3) which defines costs related to Adverse Drg Events (ADEs) were applied. Results n = 12 patients: Reason for referral by NIAS included people with multiple unused medicine compliance aids, suboptimal pain management, or confused about their medicines. Time spent by pharmacist ranged from 60 to 400 minutes (average 170 minutes per patient). Clinical pharmacist interventions (n = 62) included blood pressure measurement, deprescribing of inappropriate medicines, optimising pain management, & supply of adherence aids. 97% of clinical interventions were potentially significant at Eadon grade 4 (n = 60). Total cost avoidance due to pharmacist interventions was £5678 to £12,867, with Invest to Save £6.40 to £14.52 for every pound invested. Conclusion A collaborative pathway between medicines optimisation in older people pharmacy service and the Northern Ireland Ambulance Service, led to cost effective improvements in medicines optimisation for older people.
