Study protocol of a randomized controlled trial on two new dissemination strategies for a brief, shared-decision-making (SDM) training for oncologists: web-based interactive SDM online-training versus individualized context-based SDM face-to-face training

BACKGROUND: Oncological patients often feel left out of important treatment decisions. However, when physicians engage them in shared decision-making (SDM), patients benefit in many ways and the situation is improved. SDM can effectively be taught to physicians, but participation barriers for SDM physician group trainings are high, making it hard to convince physicians to participate. With this in mind, we aim to develop and evaluate two new dissemination strategies for a brief, SDM training program based upon a proven SDM group-training concept: an individualized context-based SDM face-to-face training (IG I) and a web-based interactive SDM online training (IG II). We aim to analyze which improvements can be achieved by IG I and II compared to a control group (CG) in physician SDM competence and performance as well as the impact on the physician-patient relationship. Furthermore, we analyze differences in satisfaction concerning the two dissemination strategies by means of a training evaluation.

METHODS/DESIGN: We examine - based on a three-armed randomized controlled trial (IG I, IG II, CG) - the effectiveness of two new dissemination strategies for a SDM training program compared to a CG receiving no SDM training (voluntary access to SDM training as an incentive for participation after completion of the study). We aim to include 162 physicians randomized to one of the three arms. There will be two assessment points in time (before intervention: T0 and post-training: T1). The main outcome is the SDM competence of physicians as measured by an established observational assessment rating system (OPTION-12) by means of consultations with Standardized Patients. Standardized Patients are individuals trained to act as "real" patients. Secondary outcome measures are the SDM performance (SDM-Q-9) and the Questionnaire on the Quality of Physician-Patient-Interaction (QQPPI) both rated by Standardized Patients as well as the physicians' training evaluation.

DISCUSSION: This trial will assess the effectiveness and acceptability of two new dissemination strategies for a brief, SDM training program for physicians. Opportunities and challenges regarding implementation in daily routines will be discussed.
