Application of an interrupted time series analysis (ITS) to evaluate the effect of universal dialysis policy from 2006 to 2016 in a province of northeastern Thailand (original) (raw)

Background: An interrupted time series (ITS) analysis is a powerful tool for policy evaluation. In Thailand, chronic kidney disease (CKD) is a public health problem that requires a long recovery time and has a high treatment cost. The universal coverage policy for renal replacement therapy (universal dialysis policy), is used to treat this disease but policy evaluation using ITS analysis has rarely been conducted. This study applied ITS analysis to test the effect of such a policy between 2006 and 2016. Methods: Data were retrieved from the electronic database of the health data center in Roi Et Province for the period between January 1, 2006 and December 31, 2016. 15,681 CKD stage 5 patients were included.
