Objective: To assess the SDM process of patients and physicians when deciding lr-sBCC therapy, as well as the factors that may influence the SDM process. Methods: A prospective, multicenter cohort study over 18-months from October 2018 to April 2020 on three tertiary university hospitals and one private hospital. Results: This study included 107 patients. There was a weak positive correlation between SDM-Q-9 and SDM-Q-Doc (rs [105] = 0.21; P = .03). Most patients (71%) chose a non-surgical treatment after the SDM process. Patients with higher satisfaction with the SDM had lower decisional conflict and decisional regret (P < .001). Patients older than 80 years had higher rates of significant decisional conflict. When evaluating treatment decisions, the highest median score on decisional conflict (22, IQR [16]; P = .01) was observed on patients who chose a surgical excision. Limitations: Patients may have self‐selected to participate. Conclusion: This study suggests that patients may prefer less invasive therapies for low-risk superficial basal cell carcinoma. The shared decision-making process may reduce decisional conflict and decisional regret.
