Abstract: Abstract Background The diagnosis-intervention packet (DIP) payment reform, utilizing big data for patient classification and payment standardization, was initially developed and piloted in China. Guangzhou, the pilot mega-city, rolled out DIP payment reform in 2018 to regulate medical expenditures. We estimated the impacts of DIP on costs and healthcare resource utilization in Guangzhou using a nine-year panel data set of Guangzhou and other regions between 2018 and 2020. Methods By employing the synthetic difference-in-difference (SDID) method, we captured changes in outcome variables before and after DIP implementation in Guangzhou and non-reforming regions. Results DIP payment reform increased per-episode inpatient costs by CNY 1574.735 (95% CI: 148.330 to 3001.140, P
