Objective To investigate the attitudes of Chinese doctors towards the difficulties they have concerning the involvement of patients in decision-making about treatment. Method We surveyed 1 088 doctors at different levels (70% internal medicine, 22% general surgery, 8% gynecology) from 20 general hospitals and 5 university hospitals covering 25 provinces and cities in China, using a simple questionnaire, which we had developed. Results A total of 780 doctors returned the questionnaire and of these only 488 (62%) had completed it. The difficulties that doctors were most concerned about focused on lack of time (27%), expressing uncertainties to patients (15%), dealing with patients who have little medical knowledge (13%), eliciting patients’ preferences (12%), and establishing a stable relationship (9%). Conclusion Increasing their knowledge of patient involvement in making treatment decisions may reinforce appropriate attitudes towards this concept among doctors.
