Relation Between Psychoactive Drugs Overdosage and Severity of Falls in Elderly People

Patients over the age of 75 with at least one psychoactive drugs in their usual treatment will be included in the study in order to assess the severity of their fall and to measure the concentrations of all psychoactive drugs identified in their blood samples. This study must include 400 patients over the age of 75 hospitalized for a fall in geriatrics or another department after going to the emergency room. Patients will be included in the study as soon as they go to the emergency room during which the blood samples will be taken and several data collected. The final inclusions and the consultations to collect the clinical and biological data essential to the achievement of the main and secondary objectives will then be carried out by a geriatrician in the patient's hospitalization department. Qualitative research and plasma assays of psychoactive drugs will be carried out by liquid phase chromatography coupled with a tandem mass spectrometer. The expected duration of the study will be 3 years.
