Abstract Objectives To determine the feasibility of pragmatic implementation strategies for three good questions (in Dutch: Drie Goede Vragen; 3GV. What are my options; what are the risks and benefits related to these options; and what does this mean for my situation?) to increase shared decision‐making (SDM) efforts in Dutch secondary care, and identify barriers and facilitators of implementation. Methods Convergent mixed‐method design: pre‐post surveys with patients attending one of six clinical departments in a Dutch Hospital, post‐intervention interviews with patients and health‐care professionals. Primary outcomes: feasibility (reach, use of 3GV). Secondary outcomes: SDM, experiences with 3GV and decision making. Interviews focused on barriers and facilitators of 3GV use. Interviews were content coded and categorized into determinants of behaviour change. Results 35% of the respondents who had heard of 3GV (52%) used all three questions. 3GV use did not lead to more SDM (SDMQ9 M = Δ0.3;SE = 2.2) but patients felt empowered to decide (88%) and to SDM (86%). Barriers were as follows: time investment, other SDM projects and perception that the need to use 3GV differs per patient/consultation. Respondents preferred to use 3GV as they saw fit for the consultation, instead of literally asking them. Facilitators: easy, accessible information materials that can be flexibly used. Conclusion Implementation of 3GV seemed feasible, although influenced by contextual characteristics (eg type of decisions, patients, on‐going interventions). 3GV contributed to important elements of SDM, and respondents were willing to apply them in a way that suited their situation. Practice implications We recommend continuation of current and new implementation strategies to enable 3GV implementation in secondary care.
