Impact of medical waste bin on contamination of patient's environment : an experimental study
Copyright © 2024. Published by Elsevier Inc..
BACKGROUND: Medical waste bins are potential source of microbial contamination in hospital environment, while there is no clear guidance for the management of them. We aimed to assess the impact of medical waste bins on patient's environment.
METHODS: This experimental study simulated microbial contamination by performing medical procedures on a patient model with fluorescent lotion. The waste bin was set as initially empty or two-thirds filled with waste, open or with a lid. The percentage of fluorescent contaminated area in designated patient's environments was analyzed by two independent observers.
RESULTS: Among a total of 120 experiments, the sides of the bins were more contaminated in open-occupied bins compared to open-empty bins and in open-occupied bins compared to lid-occupied bins (median 1.9175% vs. 0.0916% [P=0.001] and 1.9175% vs. 0.0899% [P=0.003], respectively). The top of bedside equipment trolley for preparing medical procedure was more contaminated in lid-occupied bins than open-occupied bins (median 0.0080% vs. 0.0040%, P=0.013).
DISCUSSION: In addition to reducing contamination of bin itself, the manually operated lid had potential risk of contributing microbial transmission by contaminating equipment trolley.
CONCLUSIONS: Medical waste bin should be kept no more than two-thirds full, and cautions should be taken when using manually operated lid, to avoid cross-contamination.
