Abstract

Background
Substance use may influence the onset and course of psychiatric diseases. The “Revolving door” (RD) phenomenon, which indicates repeated hospitalizations of the same patients, has become a public health.

Objectives
The aim of this study was detecting the risk factors associated to hospital readmission to psychiatric wards of drug-addicted patients.

Methods
The study considered all the admissions performed between 2006 and 2015 in Abruzzo, Italy. Only the hospital discharge registry having code 304 (drug dependence) as diagnosis was taken into account. In addition, only the patients with a psychiatric DRG were included.

Results
325 patients performed 558 psychiatric admissions during the study period (1089 person-years). The analyses of the discharge registry showed “Psychoses” as the main DRG (73.2%). An amount of 119 patients experienced a second psychiatric admission. Psychiatric readmissions were independently predicted by Schizofrenia (HR=2.061) and Anxiety disorders (HR=0.326).

Conclusions
Psychiatric hospitalization and readmission are frequent among drug-addicted patients. The subsequent RD phenomenon has become a public health issue, both for health and economic sides.
