Abstract
Objectives
to compare the efficacy and duration of cleaning and disinfection of digital oximeters with two methods in a primary care setting.Methods
microbiological culture and adenosine triphosphate assay results were evaluated in oximeters inoculated with Salmonella typhimurium, Staphylococcus aureus or Escherichia coli: after water and detergent followed by 70% ethanol (method 1); after one-step disinfectant based on benzalkonium chloride and polyhexamethylene biguanide hydrochloride (method 2); and no cleaning and disinfection (control). Effective disinfection was defined as: (1) microbial load reduction of ≥99.99%, (2) negative culture or (3) final microbial load <103.Results
effective disinfection varied between 33.3% (criterion 2) and 72.2% (criterion 3) and was similar between the two methods, while cleaning and disinfection duration in method 2 was notably shorter.Conclusions
the efficacy of the two methods was similar and suboptimal, highlighting the challenges associated with the cleaning and disinfection of electronic medical devices in primary care.
