Brief Summary
The goal of this multi-center randomized controlled trial is to determine if the clinical decision aid (BCT Aid) works to help breast cancer patients participate in decision-making and make high-quality decisions, thereby improving the rate of breast-conserving surgery and quality of life. The main questions it aims to answer are: Does the BCT Aid significantly increase the rate of breast-conserving surgery compared to usual care? Does the BCT Aid reduce decision conflict and decision regret, while improving shared decision-making and quality of life? Does the BCT Aid demonstrate better cost-effectiveness in terms of health resource utilization? Researchers will compare the BCT Aid to usual care (standard clinical consultation) to evaluate the effectiveness and cost-effectiveness of BCT Aid. Participants will: Be randomly assigned to either the intervention group (receiving the BCT Aid intervention for 6 months) or the control group (usual care). Complete assessments including decision conflict and shared decision-making at baseline (T0), post-consultation with the surgeon (T1), 6 months (T2, post-intervention), and 12 months (T3, 6 months post-intervention), decision regret at T2 and T3, and quality of life at T0, T2, and T3, with additional EQ-5D-5L measurements at baseline, 3, 6, 9, and 12 months for cost-effectiveness analysis. Have clinical outcomes (breast-conserving surgery rate) and health resource utilization data collected from medical records.

Outcome Measures
Primary Outcomes (1)
Decision conflict
Decision conflict is measured using the Decisional Conflict Scale (DCS), a 16-item instrument that assesses uncertainty in decision-making, factors contributing to uncertainty, and perceived effectiveness of decision-making. Higher scores indicate greater decisional conflict.
At baseline (T0), post-consultation with the surgeon (T1), 6 months (T2, post-intervention), and 12 months (T3, 6 months post-intervention).
Secondary Outcomes (5)
Decision regret
At 6 months (T2, post-intervention), and 12 months (T3, 6 months post-intervention).
Shared Decision-Making
At post-consultation with the surgeon (T1), 6 months (T2, post-intervention), and 12 months (T3, 6 months post-intervention).
Quality of life measured by the Functional Assessment of Cancer Therapy-Breast (FACT-B)
At baseline (T0), 6 months (T2, post-intervention), and 12 months (T3, 6 months post-intervention).
Health-related quality of life
At baseline (T0), 3 months, 6 months (T2, post-intervention), 9 months, and 12 months (T3, 6 months post-intervention).
Breast-conserving surgery rate
At 6 months (post-intervention)
Study Arms (2)
BCT Aid Intervention Group
EXPERIMENTALParticipants in this arm will receive a multimodal shared decision-making decision aid (BCT Aid) for 6 months. The BCT Aid includes three module: value model, personalized survival prediction module, and information module.
Usual Care Group
ACTIVE COMPARATORParticipants in this arm receive usual care, which consists of standard clinical consultation and routine information provision as per hospital practice.
Interventions
The BCT Aid is a multimodal shared decision-making decision aid for newly diagnosed breast cancer patients, designed to support patient participation in clinical decision-making and to improve the quality of decisions regarding surgical treatment. It consists of three core components: (1) a values module to elicit patient preferences for surgical options; (2) a personalized survival prediction module to provide individualized prognostic information; and (3) an information module offering evidence-based knowledge on breast cancer treatment, recovery, and rehabilitation. The intervention will be delivered to the BCT Aid intervention group for 6 months, with breast cancer patients receiving the tool at diagnosis and having access to it throughout the decision-making process.
Usual care consists of standard clinical consultation and routine information provision as per hospital practice. Patients receive standard care from their healthcare providers, including routine discussions regarding diagnosis, treatment options, and follow-up plans. No additional decision aid or structured shared decision-making intervention will be provided.
