EV0600 E-PosterForensic PsychiatryRetrospective cohort # From fixed upper limits to indefinite forensic protective measures: a 13-year longitudinal study in Taiwan FROM FIXED CAPS TO INDETERMINATE FORENSIC COMMITMENT: A 13-YEAR LONGITUDINAL STUDY IN TAIWAN Presenter: Chih-Chieh Chang Country: Taiwan Institution: Kaohsiung Municipal Kai-Syuan Psychiatric Hospital The duration of forensic protective measures in Taiwan shifted from a downward to an upward trend in 2017; the 2022 reform legally formalized this increase, which had already begun. The study aimed to characterize forensic patients, test whether length of stay (LoS) had increased before the 2022 reform, and assess the reform’s impact on patient turnover; Taiwan’s 2022 reform replaced a fixed five-year upper limit with an indefinite 5-plus-3-plus-n model. Using a retrospective cohort design, the study examined 262 cases subject to protective measures between 2012 and 2025; education, diagnosis, and offense type were included as covariates, LoS in days by year of admission was used as the outcome measure, and linear spline regression was performed with a knot at 2017 selected using AIC (Stata 18.0). Men accounted for 85.5% of the sample (224); 189 patients (85.9%) had a junior high school education or less, and 144 (64.6%) had substance use, with these percentages calculated using cases with nonmissing data (education n = 220, substance use n = 223). Primary diagnoses were distributed as follows: psychotic disorders, 164 (62.6%); other or cognitive disorders, 51 (19.5%); mood disorders, 29 (11.1%); and substance-related disorders, 18 (6.9%). Offense types were violent offenses, 92 (35.1%); property offenses, 72 (27.5%); offenses endangering public safety, 42 (16.0%); and other offenses, 56 (21.4%). Mean LoS was 754.2 days (SD 431.0), with a decrease of 46.8 days per year in the first phase, from 2012 to 2017, and an increase of 24.2 days per year in the second phase, from 2017 to 2025; the single-knot spline model (AIC = 3921.0) outperformed the linear model. The authors argue that the 2017 inflection point reflects a shift from treatment-focused to risk-management-focused practice following a high-profile case in 2016, and that practice changed before the law did. In conclusion, removing the upper limit without community-based forensic teams and step-down facilities risks creating bottlenecks; the question shifts from how long patients are hospitalized to how safely they return to the community, and structured risk assessment tools such as HCR-20 and DUNDRUM, along with community supervision, are considered necessary.
