Abstract：Objective To understand the medical decision-making preferences of doctors in tertiary grade A hospitals,providing evidence to promote clinical guidelines and improve healthcare service value.Methods A discrete choice model was constructed using the Delphi method.A total of 106 valid samples were collected via a questionnaire survey.The mixed logit model was used to assess doctors' preferences in medical decision-making across scenarios of hypertension,abdominal infection,and IgA nephropathy,analyzing heterogeneity in decision-making preferences based on doctors' characteristics.Results Overall,treatment efficacy,patient preference,and the value of medical exploration significantly influenced doctors' decision-making preferences(P＜0.05).In hypertension and IgA nephropathy scenarios,adverse reactions had a significant impact on decision-making preferences(P＜0.001).The relative importance of decision-making attributes was treatment efficacy＞adverse reactions＞patient preference＞medical exploration value＞cost control.Doctors with higher education levels valued treatment efficacy more in abdominal infection and IgA nephropathy scenarios(P＜0.05)and adverse reactions more in hypertension scenarios(P＜0.05).Conclusion Treatment efficacy is the primary factor in medical decision-making.Cost control plays a limited role in current decision-making,and preferences vary by disease specificity across different clinical practice scenarios.
