Drivers of Shared Decision Making in Inpatient Psychiatry: an Exploratory Survey of Patients' and Multi-Disciplinary Team Members' Perspectives.

Objective: To assess the prevalence and predictors of Shared Decision Making (SDM) in an adult, inpatient psy-chiatric setting.Method: Multi-disciplinary clinician focus groups and patient pre-testing informed the development of a survey on 4 SDM and 11 factors hypothesized to interfere with SDM. The survey was administered to 89 adult inpatients (80% response rate) and their treatment team psychiatrists, nurses, and social workers (n = 338 ratings, 95% response rate). Group differences and predictors were estimated using t and F-tests. Results: Patients' mean SDM score (n = 64, standardized Cronbach alpha = 0.858) was 3.35 +/- 1.13 (5 = highest agreement), and correlated with overall satisfaction with care (n = 61, r = 0.399, p = 0.001). Patients' disagreement with clinician's diagnosis (44% of patients) correlated with lower SDM ratings by patients (t = 2.55, df = 62, p = 0.013) and by clinicians (t = 2.99, df = 69, p = 0.004). Psychotic diagnoses were not a significant determining factor for SDM. Overall, clinicians rated SDM more favorably than patients (t =-5.43, df = 63, p < 0.001), with nurses and social workers rating SDM higher than physicians (p < 0.001).Conclusions: Diagnostic agreement / disagreement is a key predictor of SDM for patients and clinicians, while presence of psychosis is not. SDM was rated higher by clinicians than patients. SDM ratings vary significantly between clinical disciplines.
