- W2958467047 abstract "6511 Background: Because the benefits of adjuvant radiation therapy (RT) for breast cancer decrease with increasing age, the use of newer and more expensive RT modalities such as brachytherapy in the treatment of older women has been questioned. In particular, patients and policy makers may be concerned that for-profit hospitals might be more likely to use therapies with higher reimbursements. Among both younger and older Medicare beneficiaries with breast cancer, we examined whether hospital ownership status is associated with use of adjuvant brachytherapy. Methods: Using the Centers for Medicare and Medicaid Services Chronic Condition Warehouse database, we conducted a retrospective study of female Medicare beneficiaries aged 66-94 years old receiving breast-conserving surgery for invasive breast cancer in 2008 and 2009. We assessed the relationship between hospital ownership and receipt of brachytherapy, as well as overall RT (i.e. brachytherapy or whole breast irradiation) using hierarchical generalized linear models. Results: The sample consisted of 35,118 women, 8.0% of whom had undergone surgery at for-profit hospitals.Among patients who received RT, those who underwent surgery at for-profit hospitals were significantly more likely to receive brachytherapy (20.2%) than patients treated at not-for-profit hospitals (15.2%; OR for profit vs. not-for profit: 1.50; 95% CI: 1.23-1.84; p<0.001). Among women 66-79 years old, there was no relation between hospital profit status and overall RT use. However, among women age 80-94 years old, receipt of surgery at a for-profit hospital was significantly associated with higher overall RT use (OR: 1.22; 95% CI: 1.03-1.45, p=0.03) and brachytherapy use (OR: 1.66; 95% CI: 1.18-2.34, p=0.003), but not whole breast irradiation use (OR: 1.14; 95% CI: 0.96-1.36, p=0.13) Conclusions: Medicare beneficiaries undergoing breast-conserving surgery at for-profit hospitals were more likely to receive brachytherapy, a newer, less proven, and more expensive technology. Among the oldest women, who are least likely to benefit from RT, care at a for-profit hospital was associated with higher overall RT use, with this difference largely driven by the use of brachytherapy." @default.
