Abstract

Abstract: Issue/problem: Potentially inappropriate prescriptions (PIP) for the elderly constitute a major issue in the quality of ambulatory care. In France, people aged 80 years or older use on average five drugs per day. This polypharmacy is justified in most cases by multimorbidity but it increases the risk of adverse events. Description of the problem: In order to optimize general practitioners' (GPs) prescribing practices for the elderly, a project involving the Southeastern Health Regional Observatory (ORS Paca), the Regional Medical Department of Health Insurance Fund (DRSM Paca-Corse) and the Regional Union of Private Practitioners (URPS-ML Paca) was conducted in 2014-2016. Its main objective was to set up a regional mapping tool giving GPs access to drug prescriptions indicators for the elderly in their practice area. Results: Based on national guidelines and advice of experts in the field, we calculated 7 different indicators of potentially inappropriate prescriptions (PIPs) for people aged 65 years or older, using drug reimbursement data from the Health Insurance Fund. Those indicators were calculated among patient lists of GPs and covered prescriptions of benzodiazepines, non-steroidal anti-inflammatory (NSAI) drugs, new oral anticoagulants, proton pump inhibitors, antiplatelet therapy... PIPs' prevalence were calculated among GPs' lists of patients. PIPs prevalence differed between drugs type, GPs and territories: for example, the age standardized prevalence of long-term treatment with NSAI drugs varied in 2014 from 2 to 15% between municipalities and from 0 to 14% in 2017. Lessons: These results allowed to identify priority areas for intervention, in which continuous medical education sessions with an individual feedback to GPs on their own indicators were implemented, to improve prescribing practices. Key messages: A substantial proportion of elderly people receive PIPs. Medico-administrative databases can be used to produce indicators of prescription practices to be used to guide public health interventions.
