Study Summary
Large regional variation exists in the use of radiotherapy after breast-conserving surgery (BCS) for ductal carcinoma in situ (DCIS). Although patients who do not receive initial radiotherapy for DCIS are candidates for subsequent BCS if they experience a second breast event, many undergo mastectomy instead.
Primary Outcome
The investigators defined treatment intensity in a health services area to be the proportion of patients undergoing breast conserving surgery for DCIS who receive radiation therapy. Because a proportion is challenging to analyze statistically given that the precision of the estimate depends on the size of the denominator which varies across service areas, we used hierarchical modeling to categorize the health service areas into three categories (low, medium, high), using a latent variable to det
