The more slack resources, the better the quality of medical care? The evidence from the public hospitals in Beijing

Background: In recent years, the scale of Chinese hospitals and the resources they occupy are in a situation of rapid expansion. Whether these resources can be fully and effectively used and whether they are conducive to the improvement of the quality of medical care remains to be studied. Methods: : The DEA model and the panel regression model were used to analyze the slack resources status, and to study the relationship between slack resources and the quality of medical care. Results: : First, slack in 23 hospitals was on the rise from 2015 to 2018, with significant reduction in 2019. Second, low-risk mortality increased from .014% to .003% when slack resources increased from 0 to about 0.225. However, the low-risk mortality rate increased to .086% when slack resources increased to about .577. Conclusions: : There is an inverted U-shaped curve relationship between slack resources and the quality of medical care in public hospitals in Beijing. That is, a small number of slack resources in the hospital is conducive to the improvement of the quality of medical care, but when it increase to a certain level it will have a negative impact on the quality of medical care.
