The VIDYA Study-designed to Determine if Patients With a History of Basal Cell Carcinoma Are More Inclined to Return for Follow-up if Their Risk of a Subsequent Basal Cell Carcinoma is Quantitated.
An Open-Label, Single Blind Study of How Knowledge of Risk of Subsequent Basal Cell Carcinoma Affects Compliance With Requested Follow-Up in Patients With First Basal Cell Carcinoma
While current guidelines call for annual follow-up for patients with a history of basal cell carcinoma, compliance with these guidelines is imperfect. It is hypothesized that if patients are informed of the quantitative risk of a subsequent basal cell carcinoma based on individualized risk factors, the compliance rate for follow-up will improve.
The primary objective of this study is to assess one-year compliance with requested follow-up for patients with recent history of basal cell carcinoma, among those who receive standard sun avoidance counseling and request for follow-up compared to those who receive, in addition, an estimate of their mathematical risk of a subsequent basal cell carcinoma based on individualized risk factors.

Detailed Description
This is an open-label, single-blind study to evaluate the effect of informing subjects of their individualized risk of a subsequent basal cell carcinoma on proportion of subjects who achieve compliance with requested follow-up with a dermatology healthcare provider, defined as in-person follow-up within 365 days following diagnosis of initial basal cell carcinoma.
Subjects will be randomized 1:1 to "intervention" (knowledge of individualized risk) or "control" (lack of awareness of individualized risk). Investigators will be aware of the modelled risk of a subsequent basal cell carcinoma for all subjects, but only subjects randomized to the "intervention" arm will be informed of their modelled risk. All subjects will receive standard sun avoidance counseling and will be requested to follow-up no later than 365 days from initial basal cell carcinoma diagnosis.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Control
Subjects will be assigned to the control arm if their subject ID is an odd number.
Control arm subjects will not receive counseling for individualized risk assessment for developing a second basal cell carcinoma.
|
|
Experimental: Individualized risk assessment
Subjects will be assigned to the intervention arm (i.e., informed of their individualized risk assessment) if their subject ID is an even number.
Subjects in the intervention arm will be informed of their estimated 1-year, 3-year, and 5-year risk of developing a second basal cell carcinoma.
