Efficacy of the doktormitSDM training module in supporting shared decision making - Results from a multicenter double-blind randomized controlled trial.

Abstract

Training to improve physicians' shared decision making (SDM) competencies with proven effectiveness and efficiency is rare. This study evaluated the brief in situ training module 'doktormitSDM'. In a multicenter RCT, each physician recorded four consultations, each of which included a diagnostic or treatment decision (N=152 consultations from seven medical specialties). The doktormitSDM training module included two video-based individual coaching sessions (15min) at the physicians' workplaces, supplemented by a manual and a video tutorial. Primary endpoint was the compound measure SDMmass (based on the MAPPIN'SDM system) which incorporates patient and observer perceptions of involvement and doctor-patient concordance on perceived involvement. SDMmass increased significantly in the intervention group compared to the controls (effect size 0.58; p=0.05; t-test). This effect tended to persist at follow-up (effect size 0.63; p=0.06). Patients' perceived involvement increased accordingly (effect sizes 0.9/.58; p=0.01/.07). The doktormitSDM training module is effective and efficient at improving SDM competencies. This is the first SDM training to be evaluated with a compound measure simultaneously considering doctor, patient and observer ratings. Owing to its very brief form and its reference to the doctors' own consultation videos, the doktormitSDM training module meets clinicians' needs and time constraints.
