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 the setting up of clinical pharmacy activities for patients at high iatrogenic risk. The contribution of clinical pharmacists to mobile geriatric teams 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. TIn order to promote the physician-pharmacist action synergy observed in practice, the investigators decided to integrate the pharmaceutical evaluation 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, to reduce the risks of iatrogenic medicinal increase the acceptance of therapeutic interventions by the health care team. 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 p
