Socio-economic and rural-urban differences in healthcare and catastrophic health expenditures among cancer patients in China: analysis of the China Health and Retirement Longitudinal Study
Abstract Background In China, cancer deaths account for one-fifth of all deaths and exert a heavy toll on patients, families, healthcare systems, and society as a whole. This study aims to examine socio-economic and rural-urban differences in treatment, healthcare service utilization and catastrophic health expenditure (CHE) among Chinese cancer patients, and to investigate the relationship between different treatment types and healthcare service use as well as incidence of CHE. Methods We analyzed a nationally representative sample from the China Health and Retirement Longitudinal Study including 17,224 participants in 2011 and 19,569 participants in 2015. Multivariable regression models were performed to investigate the association of cancer treatments with healthcare service utilization and CHE. Results The age-adjusted prevalence of cancer is 1.37% for 2011 and 1.84% for 2015. Approximately half of the cancer patients utilized treatment for their disease, with a higher proportion of urban residents (54%) than rural residents (46%) receiving cancer treatment in 2015. CHE declined by 22% in urban areas (25% in 2011 and 19% in 2015) but increased by 31% in rural areas (25% in 2011 to 33% in 2015). There was a positive relationship between cancer treatment and outpatient visit (OR = 2.098, 95% CI = 1.453, 3.029), admission to hospital (OR = 1.961, 95% CI = 1.346, 2.857) and CHE (OR = 1.796, 95% CI = 1.231, 2.620). Chemotherapy and surgery were each associated with a 2-fold increased risk of CHE. Conclusions Meaningful changes to improve health insurance benefit packages are needed to ensure universal, affordable and patient-centered health coverage for the Chinese cancer patients.
