Does the use of shared decision-making consultation behaviors increase treatment decision-making satisfaction among Chinese women facing decision for breast cancer surgery?

ABSTRACT

OBJECTIVE: To assess the extent to which breast surgical consultations used shared decision making (SDM), identify factors associated with use of SDM, and assess if using SDM increases decision-making satisfaction. METHODS: Two hundred and eighty-three video-recorded diagnostic-treatment decision consultations between breast surgeons and women with breast cancer were assessed using the Decision Analysis System for Oncology (DAS-O) coding system designed for assessing SDM behaviors. Women completed a questionnaire at pre-consultation, one-week post-consultation and one-month post-surgery. Patient outcomes included decision conflict, patient satisfaction with medical consultation, and decision regret. RESULTS: Overall, the level of SDM behaviors was low. The extent of SDM behavior within consultation was related to greater consultation duration (p<0.001), more than one treatment being offered (p<0.001), and fewer questions raised by patients/companions (p<0.05). While use of SDM consultation did not influence post-consultation decision conflict, it increased satisfaction with information given and explained, patients' feelings of trust and confidence in their surgeons, and reduced post-surgical decision regret. CONCLUSION: These breast surgical consultations mostly adopted informed treatment decision-making approaches. Using SDM improved patient consultation and decision satisfaction. PRACTICE IMPLICATIONS The study findings highlight a need to reinforce the importance of SDM in consultations among breast surgeons.
