Abstract
Background: Shared decision-making (SDM) is integral to patient-centered care, yet its implementation in oncology remains inconsistent. This study evaluates the effectiveness of a novel digital SDM tool for cancer patients, assessing its impact on decision quality, patient activation, and satisfaction.Methods: A mixed-methods design was employed across three cancer centers from January to December 2023. A total of 240 patients with breast, colorectal, or lung cancer were randomized to usual care (n=120) or the SDM tool intervention (n=120). The tool included personalized risk communication, values clarification exercises, and a summary of options. Outcomes were measured using the Decisional Conflict Scale (DCS), Patient Activation Measure (PAM-13), and a satisfaction survey. Semi-structured interviews with 30 patients and 15 clinicians explored experiences.Results: Intervention group participants reported significantly lower decisional conflict (mean DCS 18.2 vs. 32.7, pConclusions: The SDM tool improves key patient-reported outcomes in cancer care. Tailoring tools to diverse populations and integrating them into clinical workflows are essential for broader adoption.
