Abstract

Background/aims:
This study aimed to (1) develop a decision aid for women considering participation in the Sentinel Node Biopsy versus Axillary Clearance 2 (SNAC-2) breast cancer surgical trial and (2) obtain evidence on its acceptability, feasibility, and potential efficacy in routine trial clinical practice via a two-stage pilot.

Methods:
The decision aid was developed according to International Patient Decision Aid Standards. Study 1: an initial pilot involved 25 members of the consumer advocacy group, Breast Cancer Network Australia. Study 2: the main pilot involved 20 women eligible to participate in the SNAC-2 trial in New Zealand. In both pilots, a questionnaire assessed: information and involvement preferences, decisional conflict, SNAC-2 trial-related understanding and attitudes, psychological distress, and general decision aid feedback. A follow-up telephone interview elicited more detailed feedback on the decision aid design and content.

Results:
In both pilots, participants indicated good subjective and objective understanding of SNAC-2 trial and reported low decisional conflict and anxiety. The decision aid was found helpful when deciding about trial participation and provided additional, useful information to the standard trial information sheet.

Conclusion:
The development and two-stage piloting process for this decision aid resulted in a resource that women found very acceptable and helpful in assisting decision-making about SNAC-2 trial participation. The process and findings provide a guide for developing other trial decision aids.
