A comparative study using time-driven activity-based costing in single-fraction breast high-dose rate brachytherapy: An integrated brachytherapy suite vs. decentralized workflow.

Introduction: Precision breast intraoperative radiation therapy (PB-IORT) is a novel approach to adjuvant radiation therapy for early-stage breast cancer performed as part of a phase II clinical trial at two institutions. One institution performs the entire procedure in an integrated brachytherapy suite which contains a CT-on-rails imaging unit and full anesthesia capabilities. At the other, breast conserving surgery and radiation therapy take place in two separate locations.

Time-driven activity-based costing of a novel form of CT-guided high-dose-rate brachytherapy intraoperative radiation therapy compared with conventional breast intraoperative radiation therapy for early stage breast cancer.

Introduction: Intraoperative radiation therapy is an emerging option for adjuvant therapy for early stage breast cancer, although it is not currently considered standard of care in the United States. We applied time-driven activity-based costing to compare two alternative methods of breast intraoperative radiation therapy, including treatment similar to the techniques employed in the TARGIT-A clinical trial and a novel version with CT-guidance and high-dose-rate (HRD) brachytherapy.

Methods And Materials: Process maps were created to describe the steps required to deliver intraoperative radiation therapy for early stage breast cancer at each institution.

Time-driven activity-based costing of adjuvant vaginal cuff brachytherapy for uterine cancer in an integrated brachytherapy suite.

Purpose: Adjuvant vaginal cuff brachytherapy is well tolerated and reduces the risk of local recurrence in endometrial cancer. However, there is provider variation in the number of radiation treatments, which ranges from three to six fractions. Using time-driven activity-based costing, we calculated the cost to deliver three vs six fractions to determine the value of each regimen at our brachytherapy suite with CT-on-rails.
