In shared decision-making (SDM), physicians encourage the patient to participate in the care process. The theory of planned behaviour describes that behaviour is dependent on intention. In its turn, intention is explained by attitude, subjective norm and perceived behavioural control. In orthopaedics, little is known about current SDM behaviour and how to promote it.The aim of the present study was to gain insight into the SDM behaviour of orthopaedic residents and supervisors by measuring levels of intention, attitudes, subjective norms and perceived behavioural control. Furthermore, we aimed to determine the predictors of intention for SDM.
A questionnaire survey study was conducted among orthopaedic surgeons and residents working in the care of hip and knee osteoarthritis, to determine their intentions, attitudes, subjective norms and perceived behavioural control regarding SDM.
Of the 385 physicians approached, 71 residents and 64 orthopaedic surgeons participated. Residents and the supervisors alike had positive intentions regarding SDM. Intention for SDM behaviour was explained by attitude, subjective norm and perceived behavioural control, with perceived behavioural control having the strongest association. In residents, the intention to engage in SDM was more hampered by a lower level of perceived behavioural control than in surgeons.
Physicians are willing to perform SDM and consider SDM as favourable in the orthopaedic clinic. The implementation of SDM is mainly hampered by experienced barriers that they cannot control. These findings underline the importance of incorporating SDM in the curriculum of postgraduates. Possibilities for efficient SDM implementation should be explored, to overcome perceived barriers.
