    BACKGROUND: The feasibility of shared decision making (SDM) for patients with schizophrenia remains controversial due to the assumed inability of patients to cooperate in treatment decision making. This study evaluated the feasibility and efficacy of SDM in patients upon first admission for schizophrenia. METHODS: This was a randomized, parallel-group, two-arm, open-label, single-center study conducted in an acute psychiatric ward of Numazu Chuo Hospital, Japan. Patients with the diagnosis of schizophrenia upon their first admission were randomized into a SDM intervention group or a usual treatment group in a 1:1 ratio. The primary outcome was patient satisfaction at discharge. The secondary outcomes were attitudes toward medication at discharge and treatment continuation at 6 months after discharge. RESULTS: Twenty-four patients were randomly assigned. The trial was prematurely terminated due to slow enrollment. At discharge, the mean score on satisfaction was 23.7 in the SDM group and 22.1 in the usual care group (unadjusted mean difference: 1.6; 95% CI: -5.2 to 2.0). Group differences were not observed in attitude toward medication and treatment continuation. There was no statistically significant difference between the groups for the mean Global Assessment of Functioning score at discharge or length of stay as safety endpoint. CONCLUSIONS: No statistical differences were found between the SDM group and usual care group in the efficacy outcomes and safety endpoints. Large trials are needed to confirm the efficacy of the SDM program upon first admission for schizophrenia. TRIAL REGISTRATION: The study has been registered with ClinicalTrials.gov as NCT01869660 (registered 27 May, 2013).

    BACKGROUND: Shared decision making is a promising model for patient-centred medicine, resulting in better clinical outcomes overall. In the mental health field, interventions that consider the patient-centred perspective--such as patient quality of life, involvement in the treatment, treatment satisfaction, and working alliance--have increased and better clinical outcomes discovered for patients with schizophrenia. However, few studies have examined the efficacy of shared decision making for schizophrenia treatment. The objective of this study is to evaluate the effect of a shared decision making intervention compared to treatment as usual on patient satisfaction at discharge for first-admission patients with schizophrenia. METHODS/DESIGN: This is a randomised, parallel-group, two-arm, open-label, single-centre study currently being conducted in an acute psychiatric ward of Numazu Chuo Hospital, Japan. We are recruiting patients between 16 and 65 years old who are admitted to the ward with a diagnosis of schizophrenia without prior experience of psychiatric admission. Fifty-eight participants are being randomised into a shared decision making intervention group or a treatment as usual control group in a 1:1 ratio. The intervention program was developed based on a shared decision making model and is presented as a weekly course lasting the duration of the patients' acute psychiatric ward stay. The primary outcome measure is patient satisfaction at discharge as assessed by the Client Satisfaction Questionnaire. Due to the study's nature, neither the patient nor staff can be blinded. DISCUSSION: This is the first randomised controlled trial to evaluate the efficacy of shared decision making for patients with early-treatment-stage schizophrenia. The intervention program in this study is innovative in that it includes both of the patient and staff who are involved in the treatment. TRIAL REGISTRATION: The study has been registered with ClinicalTrials.gov as NCT01869660.
