Drug fee and examination fee were significantly affected (P<0.01). However, the re-admission rate was significantly improved (P<0.10).ConclusionThe implementation of single-disease quota payment in Chengdu controlled the medical expanses growth effectively, but it is necessary to prevent its side effects.
