Fragmentation of Care and Its Association With Survival and Costs for Patients With Breast Cancer in Colombia.

Purpose: Breast cancer care requires a multimodal approach and a multidisciplinary team who must work together to obtain good clinical results. The fragmentation of care can affect the breast cancer care; however, it has not been measured in a low-resource setting. The aim of this study was to identify fragmentation of care, the geographic variation of this and its association with 4-year overall survival (OS), and costs of care for patients with breast cancer enrolled in Colombia's contributory health care system.
