Impact of a Hospital Medication Expertise on Unplanned Hospitalizations at 3 Months of Nursing Homes Patients

The use of drugs in the elderly population remains a major public health problem worldwide. Technological advances and the development of new drugs have helped to extend life expectancy. However, the complex process of aging, resulting in changes in physiological functions, may affect the pharmacodynamics and kinetics of medications taken by the elderly. In addition, polypharmacy, due to multiple comorbidities, may also lead to an increased risk of drug or field interaction and the use of potentially inappropriate drugs (PID), increasing the risk of drug iatrogenic use in older users.

With a view to optimizing drug prescriptions and preventing drug iatrogenic disease in the elderly, and in the context of a university-based research and teaching approach, the AP-HM pharmacy initiated , in collaboration with certain clinical departments, the setting up of clinical pharmacy activities for patients at high iatrogenic risk. These activities were established and formalized in close collaboration with the doctors of the departments concerned, the geriatrics center and the geriatric mobile teams in particular, and were the subject of specific funding within the framework of the Instruction N ° DGOS / PF2 / 2016/49 of the 19/02/2016 relating to the call for project of implementation of the clinical pharmacy in health facility.

The contribution of clinical pharmacists to mobile geriatric teams (intra-hospital and outpatient), who carry out more than 2,200 geriatric assessments a year, is a way to optimize the efficiency of the medication management of the elderly person hospitalized out of hospital. geriatric service and EHPAD. In order to promote the physician-pharmacist action synergy observed in practice, the investigators decided to integrate the pharmaceutical evaluation (medication review) with the geriatric evaluation. This new cooperation makes it possible to improve the knowledge of the treatments taken by the patients, to raise awareness on the observance of the treatments and to facilitate the administration of the drugs (choice of the adapted galenic forms), to reduce the risks of iatrogenic medicinal increase the acceptance of therapeutic interventions by the health care team (attending physician, coordinator, nurse). Indeed, the first results show that the mobile team's medico-pharmaceutical interventions have a much higher acceptance rate than medical or pharmaceutical interventions alone.

However, the economic context and the human resources allocated do not make it possible to ensure an efficient service throughout the territory and in particular in nursing homes outside the city where the CHU (Marseille) is located. In order to increase the number of evaluations, the investigators propose to develop a tele-expertise of a medico-pharmaceutical hospital team (EHMP) and evaluate the impact for patients residing in nursing homes in the context of a high-level study.
