Abstract
Objectives: We aimed to investigate the association between fragmented cancer care in the early phase after cancer diagnosis and patient outcomes using national insurance claim data.Methods: We identified National Health Insurance beneficiaries diagnosed with lung cancer in South Korea from 2010 to 2014. We included 1,364 lung cancer patients with reduced immortal time bias and heterogeneity. We performed multiple regression analysis using a generalized estimate equation with a gamma distribution for medical expenditures.Results: Among the 1,364 patients with lung cancer, 12.8% had fragmented cancer care. Healthcare costs were higher in fragmented cancer care for both during diagnosis to 365 days and diagnosis to 1,825 days. Linear regression results showed that fragmented cancer care was associated with 1.162 times higher costs during the period from diagnosis to 365 days and 1.163 times the cost for the period from diagnosis to 1,825 days.Conclusion: We found fragmented cancer care is associated with higher medical expenditure. Future health policy should consider the limitation of patients’ free will when opting for fragmented cancer care, as there are currently no control mechanisms.
