Objective: To examine the effects of the newly developed care model for substance-induced psychiatric disorders (Jitprapassorn Model) compared with the conventional care model.
Methods: A retrospective study was conducted among patients with substance-induced psychiatric disorders admitted to the psychiatric ward at Phang Nga Hospital. Patients were divided into two groups based on the service period: 1) the conventional care, in which all treatment was provided within the hospital, and 2) the Jitprapassorn Model, which emphasizes holistic care activities and family participation. The Jitprapassorn Model consists of three phases: the admission/crisis phase, the rehabilitation phase in the Mini Thanyarak Center, and the outpatient follow-up phase. Outcomes included adherence to scheduled follow-up visits over a 6-month period, urine drug screening results, and caregiver burden using the Zarit Burden Interview. Data were analyzed using chi-square test, Fisher’s exact test, and the Wilcoxon signed-rank test.
Results: The Jitprapassorn Model group (n = 23) and the conventional care group (n = 22) were not significantly different in baseline characteristics, substance use patterns, or treatment history prior to receiving services. After the services, the Jitprapassorn Model group demonstrated a significantly higher rate of attendance at the 6-month follow-up than the conventional care group. The Jitprapassorn Model group also showed a statistically significant reduction in caregiver burden scores at 1-week follow-up (Z = -4.02, p < .001), whereas the conventional care group showed a non-significant reduction. However, there was no statistically significant difference between the two groups in the rate of negative urine drug screening results.
Conclusion: The Jitprapassorn Model showed potential to improve retention in the treatment system among patients with substance-induced psychiatric disorders and reduce caregiver burden compared with the conventional care model.
