Analysis on the implementation effect of single disease payment policy for day surgery based on difference-in-differences model / 中华医院管理杂志

Objective:To analyze the implementation effect of single disease payment policy for day surgery (hereinafter referred to as the policy), for references for the reform of medical insurance payment.Methods:By collecting the information of inpatients from 2017 to 2019 in a tertiary hospital, the research group took patients with colorectal benign tumor and nodular goitre as the policy implementation group and the control group respectively. 2017-2018 was the pre implementation stage of the policy, and 2019 was the post implementation stage of the policy. The difference-in-differences (DID) model was used to analyze the changes in indicators such as length of stay and hospitalization expenses after policy implementation, under whether the policy is implemented or not, as well as before or after policy implementation.Results:A total of 2 419 patients were included, including 927 patients with nodular goiter in the control group and 1 492 patients with colorectal benign tumors in the policy implementation group (688 patients before the policy implementation and 804 patients after the policy implementation). The results of DID showed that the hospital days for patients with colorectal benign tumor decreased by 56.53%, the hospitalization expenses decreased by 26.51%, the out-of-pocket expenses decreased by 26.66%, the treatment expenses increased by 11.96%, the drug expenses decreased by 50.29% and the consumables expenses decreased by 20.23% after the implementation of the policy.Conclusions:The implementation of the policy could reduce length of stay, hospitalization expenses and out-of-pocket expenses, optimize the structure of hospitalization expenses, improve the efficiency of hospital diagnosis and treatment, and help the hospital realize its transformation from a size expansion to a quality and benefit expansion.

An empirical study on the effect of Beijing's separation of clinic from pharmacy reform / 中华医院管理杂志

Objective To evaluate the effect of Beijing' s separation of clinic from pharmacy reform.Methods Use difference-in-difference method based on dataset on patients having Urban Worker Medical Insurance from twelve state-owned hospitals.Results The reform incurs a decrease in the outpatient and inpatient expenditure on medicine per visit (30％ and 21％,respectively),a decline in hospital's pharmaceutical ratio (9 percentages and 4 percentages,respectively); reduces the outpatient and inpatient expenditure per visit (19 ％ and 8 ％,respectively),with a decrease in the out-of-pocket part (23％ and 3％,respectively),and a slight increase in the Medical Insurance's part (2％); raises hospital's turnover (11％),outpatient's visits (22％),and inpatient visits (43％).Conclusion The reform encourages physicians to prescribe more scientifically,and hence reduces patient 's expenditure on medicine and hospital's pharmaceutical ratio; leads to a decrease in patience' s expenditure per visit;raises hospital's turnover; and doesn't cause a significant increase in the expenditure from social medical insurance.

Impact of DRG Payment on the Length of Stay and the Number of Outpatient Visits After Discharge for Caesarean Section During 2004-2007 / 예방의학회지

OBJECTIVES: The purpose of this study was to examine the impact of Diagnosis-Related Group (DRG)-based payment on the length of stay and the number of outpatient visits after discharge in for patients who had undergone caesarean section. METHODS: This study used the health insurance data of the patients in health care facilities that were paid by the Fee-For-Service (FFS) in 2001-2004, but they participated in the DRG payment system in 2005-2007. In order to examine the net effects of DRG payment, the Difference-In-Differences (DID) method was adopted to observe the difference in health care utilization before and after the participation in the DRG payment system. The dependent variables of the regression model were the length of stay and number of outpatient visits after discharge, and the explanatory variables included the characteristics of the patients and the health care facilities. RESULTS: The length of stay in DRG-paid health care facilities was greater than that in the FFS-paid ones. Yet, DRG payment has no statistically significant effect on the number of outpatient visits after discharge. CONCLUSIONS: The results of this study that DRG payment was not effective in reducing the length of stay can be related to the nature of voluntary participation in the DRG system. Only those health care facilities that are already efficient in terms of the length of stay or that can benefit from the DRG payment may decide to participate in the program.
