Temporal-spatial distribution characteristics and associated socioeconomic factors of medical expenditures for rural patients with chronic kidney disease in Fujian Province, Southeast China

The out-of-pocket ratio of rural patients with CKD decreased, but suffering from CKD was still catastrophic. The distribution of medical expenditures in rural residents was uneven and there was temporal-spatial heterogeneity in the associations between per capita annual medical expenditures and socioeconomic factors. It is necessary to improve the awareness and health literacy of residents, systematically carry out CKD screening program in high-risk populations, incorporate CKD into the National Basic Public Health Service Program and increase the number of health technicians which could effectively delay the disease progression and reduce medical expenses.
