Reusable textile microfiber and laundry in healthcare: Critical analysis of problematic published information

Recent analyses of environmental services products and practices in healthcare have covered the concepts of hygienically clean, mechanisms of cleaning, and comparison of reusable and disposable textile microfiber products. In 11 referred papers, it was discovered that three had sufficient factual errors to influence the citations found in the broader literature. This study evaluating these problematic papers is an obligation of the scientific community for accuracy. In light of newer data on the efficacy of important textiles for microfiber cleaning, these previous studies were reexamined to see if methodological corrections are needed. Closer investigation of the authors’ data was used to ascertain the validity of their initial conclusions. These current reevaluations reverse conclusions in these journal articles. It appears factors such as multi-variant statistical comparisons, combining variables, and use of extremely high inoculum for cleaning led to the wrong conclusions in these three papers. The revised results show that for hospital surface cleaning with reusable textile microfiber products, no detectable levels were found for two of the most challenging organisms for hospital-acquired infections, methicillin-resistant Staphylococcus aureus and Clostridium difficile. Commercial laundry was substantially better than hospital laundry and reusable microfiber products improved with use.
