[Involuntary Psychiatric Hospitalizations: From request to a call center to hospitalization].

Background: Involuntary psychiatric hospitalization (IPH) is a heavy and complex psychiatric exception measure. In the Seine-Saint-Denis department (low medical density), the evaluation of the patient in psychiatric decompensation is the responsibility of the out-of-hours general practitioners (GP) mandated by the call center. Their feeling is the non-achievement of the procedure once the patient arrives at the emergency room. We aimed to evaluate the outcome of patients following a request for IPH from these GP.

Methods: We conducted a retrospective study based on all requests for IPH received during 2016 at the Seine-Saint-Denis emergency medical call center. The characteristics of the call and the patient, as well as the decisions of the regulator and the GP were collected. The decision of hospitalization in the emergency room was sought for patients referred for IPH.

Results: Of the 7541 calls for decompensation, 539 were for an IPH. These calls occurred during non-working hours in 55 % of cases. A GP was involved in more than two-thirds of the cases and requested an IPH for 240/304 (79 %) patients. Patients were male in 56 % of cases with an average age of 40 (±16) years. IPH was confirmed for 132 (61 %) patients. This rate did not differ from the 65 % reported in the literature (Z-test, P=0.26). Voluntary hospitalization was performed for 37 (17 %) other patients.

Discussion: The IPH rate for patients referred by GP mandated by the call center was comparable to that following the requests of the attending physicians, validating their intervention in this critical context.
