Abstract

Abstract:

Objective

To measure the efficiency of continuous renal replacement therapy technology (CRRT) in intensive care units (ICUs) in Chinese medical institutions and analyze the influencing factors, to provide a reference for further standard CRRT services in China and improving the efficiency of ICU in local medical institutions.

Methods

The ICU input-output information of 126 medical institutions in five provinces of China from March 1 to 31, 2021 was collected.The three-stage data envelope analysis(DEA) model and super efficiency model were used to measure the CRRT efficiency of ICU.

Results

The average comprehensive efficiency, pure technical efficiency and scale efficiency of the 126 medical institutions were 0.300, 0.506 and 0.598, respectively.The comprehensive efficiency of the five provinces was C (0.364)＞ A (0.345)＞ B (0.286)＞ D (0.213)＞ E (0.169), and the hospital grade showed a positive and significant relationship with the efficiency of CRRT.

Conclusion

The overall efficiency level of CRRT in ICUs of sample institutions in five provinces is low with regional differences.It is necessary to optimize hospital internal control operation management, establish CRRT resource allocation standards, innovate and standardize human resource management and training mechanisms, and carry out CRRT through interdisciplinary cooperation.
