Hospitalizations with post-traumatic stress disorder in France between 2013 and 2022: a nationwide retrospective study.

Abstract

Introduction: The lifetime prevalence of PTSD ranges from 6 to 20% and is often associated with comorbid disorders. Despite the significant impact of PTSD, specific data on healthcare utilization related to PTSD remain limited. This study aims to characterize PTSD-related hospitalizations in France over the past decade.

Methods: This nationwide longitudinal retrospective study analyzed PTSD-related hospitalizations in France from 2013 to 2022 using the French National Hospitals Database. Data included discharge records from general and psychiatric hospitals, detailing demographics, admission/discharge dates, ICD-10 diagnoses, and hospitalization specifics.

Results: Between 2013 and 2022, 69,108 patients underwent 125,349 hospitalizations with a PTSD diagnosis (0.4% of all inpatient cases) in France. Psychiatric facilities accounted for 74,988 hospitalizations (1% of all psychiatric inpatient cases in France), while general hospitals recorded 50,361 hospitalizations (0.02% of all non-psychiatric inpatient cases). The percentage of inpatients diagnosed with PTSD increased from 0.68 to 2.22% in psychiatric facilities and from 0.02 to 0.04% in general hospitals over the study period. Females were younger in both settings and had longer stays compared to males in psychiatric facilities. Over time, there was a decrease in median age and an increase in part-time hospitalizations in psychiatric facilities. Mood disorders, stress-related disorders, and substance use disorders were prevalent comorbidities in both settings.

Conclusions: This study highlights a rise in PTSD-related hospitalizations in France, particularly in psychiatric facilities and after 2019, with high rates among women and an increase in hospitalization of younger individuals. These findings highlight the necessity for improved care strategies tailored to the increasing number of younger patients with PTSD.
