Establishment and application of an infection prevention and control system for patients undergoing continuous renal replacement therapy.

BACKGROUND

Continuous renal replacement therapy (CRRT) is essential for critically ill patients but carries a high risk of hospital-acquired infections. Implementing an effective infection prevention and control system is critical for improving patient safety.

METHODS

This study utilized the Delphi method to develop a comprehensive infection prevention and control indicator system specifically designed for CRRT patients. A total of 126 patients treated at Xuanwu Hospital, Capital Medical University from January to December 2023 were included in the study. They were divided into a control group ( = 62), which received standard care, and an observation group ( = 64), which adopted the newly developed indicator system. Adverse event rates and nursing quality scores were compared between the two groups.

RESULTS

The final indicator system consisted of 3 primary, 9 secondary, and 27 tertiary indicators, with expert consensus reflected by a reliability coefficient of 0.795. The observation group demonstrated a significantly lower incidence of adverse events (3.12% vs. 16.12%, < 0.05) and higher nursing quality scores across three dimensions (basic care, equipment management, and nursing safety) compared to the control group ( < 0.05).

CONCLUSION

The infection prevention and control indicator system for CRRT patients exhibited strong reliability and scientific validity. Its implementation led to a significant reduction in infection rates and improvements in nursing quality, highlighting its potential for broader clinical adoption.
