Interventions to optimize drug therapy showed a reduction in the number of potentially inappropriate medications, but their impact on health, has rarely been evaluated. If an association with death has been established, the link with the loss of functional autonomy, which leads to reduced quality of life and significant cost of care, has not been investigated. The evolution towards functional disabilities, frequent with aging has many causes, among which some could be prevented. The optimization of drug prescriptions could thereby delay or prevent the loss of functional autonomy by reducing the risk of adverse events, such as falls or cognitive decline and improving the management of chronic diseases. Our hypothesis is that an optimization program of the drug prescribing may slow progression to functional dependence. To assess the effect of the optimization program of drug prescribing on the level of functional autonomy, a multicenter Randomized Controlled Trial will be conducted in geriatric and memory consultations.
