The psychiatric hospital discharge database (RIM-P): An essential tool for the surveillance of hospitalization after a suicide attempt

Epidemiological surveillance of suicide attempts is essential for monitoring indicator trends in the evaluation of prevention actions. As part of this surveillance, analysis of data from hospitalization for suicide attempts is particularly useful. For the first time, data from two national hospital discharge databases, the "Programme de médicalisation des systèmes d'information en médecine, chirurgie, obstétrique" (PMSI-MCO) and the " Recueil d'information médicalisé en psychiatrie" (RIM-P) have been analyzed jointly. All patients aged 10 or more hospitalized in 2012 in medicine, surgery or psychiatry departments in metropolitan France have were included. Through 2012, 89,072 patients (62% females and 38% males) totalized 134,051 hospital stays following a suicide attempt, with 93.4% (n=83,196) in medicine or surgery wards and 32.1% (n=28,594) in psychiatry wards (solely or transferred after a stay in medicine or surgery). However, among the patients transferred to psychiatry after hospitalization in medicine or surgery for suicide attempt, 82.4% had no suicide attempt code noted at their discharge from psychiatry. One or more psychiatric diagnoses were observed in 75% of the patients hospitalized for suicide attempt. The most common diagnoses in men and in women were mood disorders (46%), particularly depression (42%; 44% in women and 38% in men). Mental disorders related to alcohol use were noted in more than a quarter of the patients, more frequently in men (37%) than in women (21%). Some diagnoses were rarely noted in medicine or surgery, such as anxiety disorders and disorders of adult personality and behavior. Improvement of the epidemiological surveillance of suicide attempts requires a systematic coding of hospitalizations in psychiatry as well as in medicine and surgery. Data from hospitalization in psychiatry yield a more precise identification of psychiatric co-morbidities associated with suicide attempts. The frequent presence of mental problems associated with suicide attempts should encourage clinicians to search for these symptoms systematically as soon as possible after admission of the patient.
