Disappointing evaluation of a shared decision-making intervention for residents and orthopaedic surgeons

Research output: Contribution to journalArticleAcademicpeer-review


OBJECTIVE: To evaluate a shared decision-making (SDM) intervention in orthopaedic hip and knee osteoarthritis care.

METHODS: Using a pre- post intervention design study, we tested an intervention, that included a decision aid for patients (ptDA) and a SDM training course for residents in training and orthopaedic surgeons. The theory of planned behaviour was used for intervention development. Primary outcomes included patient reported decisional conflict, SDM, and satisfaction. Secondary outcomes were physicians' attitude and knowledge, and uptake of the ptDA.

RESULTS: 317 patients were included. The intervention improved physicians' knowledge about SDM but had no effect on the primary outcomes. 19 eligible patients used the ptDA (17%). SDM was higher for middle educated patients compared to lower educated (mean difference 9.91, p=0.004), patients who saw surgeons instead of residents (mean difference 5.46, p=0.044) and when surgery was chosen and desired by patients compared to situations where surgery was desired but not chosen (mean difference 15.39, p=0.036).

CONCLUSION: Our multifaceted intervention did not improve SDM and ptDA uptake was low.

PRACTICE IMPLICATIONS: In orthopaedic hip and knee osteoarthritic care other ways should be explored to successful implement SDM. Since residents received lower SDM scores, special focus should go to this group.
