Abstract
People with personality disorders (PDs) are often admitted to psychiatric emergency services due to the frequent repetition of acute crises. This study drew on the ICD diagnostic records of 2,634 individuals with PDs who were admitted to a specialized inpatient psychiatric crisis unit over a 6-year period. Multiple logistic regressions and survival regressions were performed to examine whether PD categories, gender, and other individual, interpersonal, and precipitating factors were associated with readmission and time-to-readmission. The results showed a 16.1% readmission rate. Of these, 99.5% of readmissions occurred within 4 years following the first admission. Gender was the main factor associated with both readmission and time-to-readmission: while men were readmitted faster, more women in total were readmitted for a second psychiatric emergency hospitalization. Findings also indicated that readmission rate and time-to-readmission differed following the category of PD: readmission rate in a ratio of 1-2 (from 8% to 10% for dissocial and paranoid PD up to 19%-21% for impulsive and borderline PD), and time-to-readmission in a ratio of 1-5 (from 1 month for anankastic and dependent, to 5 months for impulsive, histrionic and anxious-avoidant PD). Limitations of this naturalistic study include a lack of self-reported measures and generalizability to less specialized emergency settings. Future research should include a prospective longitudinal design using standardized scalable measurement tools to improve the completeness and accuracy of the data concerning the psychological processes involved in risk and time-to-readmission after brief hospitalizations in emergency psychiatry.
