Clinical efficacy of a novel lumened instruments cleaning device in enhancing cleaning quality and reducing the risk of health care-associated infections.

BACKGROUND: The structure of lumened instruments is precise, complex, and frequently used in clinical settings. Traditional cleaning devices exhibit cleaning blind spots, resulting in suboptimal disinfection and an increased risk of hospital-acquired infections. This study aims to evaluate the clinical effectiveness of a novel cleaning device for lumened instruments.

METHODS: A total of 240 used suction lumened instruments recovered from the sterilization supply center were selected and randomly divided into a control group (standard cleaning basket) and an experimental group（novel cleaning device for lumened instruments）, each consisting of 120 instruments. Cleaning quality was assessed using visual inspection, cotton swab testing, and ATP bioluminescence detection methods. Additionally, cleaning and drying times were recorded, and the cleaning pass rate was calculated. Data analysis was performed using SPSS version 22.0.

RESULTS: All 3 detection methods indicated that the cleaning pass rate in the experimental group was significantly higher than that in the control group (P < .05). Furthermore, the drying time in the experimental group was significantly shorter than that in the control group (P < .05).

CONCLUSIONS: The novel cleaning device for lumened instruments effectively improves cleaning quality and drying efficiency, thereby reducing the risk of hospital-acquired infections.
