Shared decision-making quality and decisional regret in patients with low-risk superficial basal cell carcinoma: A prospective, multicenter cohort study.

BACKGROUND

Many therapies are available to treat low-risk superficial basal cell carcinoma (lr-sBCC), which may complicate the shared decision-making (SDM) process.

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 was conducted over 18 months, from October 2018 to April 2020, in 3 tertiary university hospitals and 1 private hospital.

RESULTS

This study included 107 patients. There was a weak positive correlation between Shared Decision-Making Questionnaire-Patient version (SDM-Q-9) and Shared Decision-Making Questionnaire-Physician version (SDM-Q-Doc) (Spearman's correlation coefficient [] [105] = 0.21;  = .03). Most patients (71%) chose a nonsurgical treatment after the SDM process. Patients with higher satisfaction with the SDM had lower decisional conflict and decisional regret ( < .001). Patients aged >80 years had higher rates of significant decisional conflict. When evaluating treatment decisions, the highest median score for decisional conflict (22, IQR [16];  = .01) was observed among patients who chose a surgical excision.

LIMITATIONS

Patients may have self-selected to participate.

CONCLUSION

This study suggests that some patients may prefer less invasive therapies for lr-sBCC. The SDM process may reduce decisional conflict and decisional regret.
