Abstract

Background: The processing of medical textiles before reuse plays a crucial role in controlling and interrupting the transmission chain of hospital-acquired pathogens. Evaluating the effectiveness of the washing and drying process in reducing microbial contamination on medical textiles is of practical significance, contributing to the reduction of hospital-acquired infections. Objectives: 1) To determine the distribution of microorganisms on regular textiles and surgical textiles currently in use at Can Tho University of Medicine and Pharmacy Hospital; 2) To evaluate the intervention effectiveness of the washing and drying process in reducing the level of bacterial contamination on medical textiles. Materials and methods: Fifty samples of medical textiles, including regular textiles and surgical textiles, were collected at three stages: pre-washing, post-washing, and post-drying. The samples were cultured, isolated, and bacteria were identified. Results: After use, 100% of the medical textile samples showed the presence of microorganisms, with Staphylococcus species being the most prevalent in both regular textiles (17.9%) and surgical textiles (23.3%). The lowest prevalence was found in Klebsiella pneumoniae (3.6%) for regular textiles and Pseudomonas aeruginosa (3.3%) for surgical textiles. Washing alone, using temperature and chemicals, was unable to eliminate microorganisms. However, the combination of washing and drying processes helped in the complete removal of microorganisms. Conclusions: The washing and drying process implemented at Can Tho University of Medicine and Pharmacy Hospital successfully eliminated 100% of the adherent microorganisms on the textiles after use (p < 0.05).
