To characterize overall receipt and timeliness of radiation therapy (RT) following breast-conserving surgery among Medicaid-insured patients.
State cancer registry data linked with Medicaid claims from 2003 to 2009 were analyzed. Multivariate logistic and Cox proportional hazards regressions were employed.
Overall, 81% of patients received guideline-recommended RT. Significant variation in timing of RT initiation was documented. Having fewer comorbitidies and receiving chemotherapy were correlated with higher odds of RT initiation within 1 year.
Although RT use in Medicaid-insured women appears to have improved since earlier studies, documented delays in RT are troublesome and warrant further investigation.
描述接受保乳手术后的医疗补助保险患者接受放射治疗（RT）的总体情况和及时性。
对 2003 年至 2009 年的国家癌症登记处数据与医疗补助索赔进行了链接分析。采用多变量逻辑回归和 Cox 比例风险回归进行分析。
总体而言，81%的患者接受了指南推荐的 RT。记录到 RT 开始时间存在显著差异。合并症较少和接受化疗与一年内 RT 开始的可能性更高相关。
尽管医疗补助保险女性接受 RT 的使用率似乎比早期研究有所提高，但 RT 延迟的情况令人困扰，需要进一步调查。
