Care Fragmentation in Patients with Differentiated Thyroid Cancer.
Academic Article
Overview
abstract
BACKGROUND: Among surgical patients, care fragmentation (CF) is associated with worse outcomes. However, oncologic literature documents an association between high surgical volume and improved outcomes, favoring centralized cancer-surgery centers and thus predisposing to CF in patients with surgically treated tumors. We aimed to identify features associated with CF and ascertain differences in overall survival (OS) among patients with differentiated thyroid cancer (DTC). METHODS: The National Cancer Database was queried for DTC patients diagnosed from 2009 to 2017. Patients experienced CF if part of their treatment was performed outside of the reporting facility or an associated office. A multivariable logistic regression analysis identified independent features associated with CF. A Cox multivariable regression analysis assessed the impact of CF on OS. A Kaplan-Meier analysis compared survival differences between patients experiencing CF or unified care (UC). RESULTS: A total of 131,620 patients were included. Among them, 70,204 (53.3%) experienced CF and 61,416 (46.7%) experienced UC. Age < 55, residing in high-income areas, and stage 3 and 4 tumors were features independently associated with CF, whereas uninsured patients were less likely to experience CF than the privately insured. The features most strongly associated with CF were treatment at highest thyroid cancer-surgery volume institutions and traveling in the top distance quartile. While patients with CF experienced minor delays in time from diagnosis to surgery, 5-year OS was improved among patients with CF compared to UC for those with Stage 1-3 disease. CONCLUSIONS: Among patients with DTC, CF is associated with treatment at a highest thyroid cancer surgery volume facility and improved OS in a setting of minor treatment delays.
