Background Palliative systematic treatment offers uncertain and often limited benefits, and the burden can be high. Hence, treatment decisions require shared decision making (SDM). This trial examined the independent and combined effect of an oncologist training and a patient communication aid on SDM. Methods In this multicenter randomized controlled trial with four parallel arms (2016–2018), oncologists (n = 31) were randomized to receive SDM communication skills training or not. The training consisted of a reader, two group sessions, a booster session, and a consultation room tool (10 hours). Patients (n = 194) with advanced cancer were randomized to receive a patient communication aid or not. The aid consisted of education on SDM, a question prompt list, and a value clarification exercise. The primary outcome was observed SDM as rated by blinded observers from audio‐recorded consultations. Secondary outcomes included patient‐reported SDM, patient and oncologist satisfaction, patients’ decisional conflict, patient quality of life 3 months after consultation, consultation duration, and the decision made. Results The oncologist training had a large positive effect on observed SDM (Cohen's d = 1.12) and on patient‐reported SDM (d = 0.73). The patient communication aid did not improve SDM. The combination of interventions did not add to the effect of training oncologists only. The interventions affected neither patient nor oncologist satisfaction with the consultation nor patients’ decisional conflict, quality of life, consultation duration, or the decision made. Conclusion Training medical oncologists in SDM about palliative systemic treatment improves both observed and patient‐reported SDM. A patient communication aid does not. The incorporation of skills training in (continuing) educational programs for medical oncologists is likely to stimulate the widely advocated uptake of shared decision making in clinical practice. Trial registration. Netherlands Trial Registry NTR 5489. Implications for Practice Treatment for advanced cancer offers uncertain and often small benefits, and the burden can be high. Hence, treatment decisions require shared decision making (SDM). SDM is increasingly advocated for ethical reasons and for its beneficial effect on patient outcomes. Few initiatives to stimulate SDM are evaluated in robust designs. This randomized controlled trial shows that training medical oncologists improves both observed and patient‐reported SDM in clinical encounters (n = 194). A preconsultation communication aid for patients did not add to the effect of training oncologists. SDM training effectively changes oncologists’ practice and should be implemented in (continuing) educational programs. Decisions about treatment for advanced cancer require shared decision making, involving both physician and patient. This trial examined the independent and combined effect of oncologist training and a patient communication aid on shared decision making about palliative chemotherapy.
