Disinfection efficacy studies n three different disinfection methods in health care facilities by ATP method

Objectives: Nosocomial infection has always been a significant topic in the field of public health. The disinfection procedures involved in health care facilities are extremely important to prevent potential transmission of diseases. Therefore, this study was performed to compare the disinfection efficacy between three different disinfection methods (Accel wipes, Hubscrub industrial washer, and Steam vapor) on three pieces of non-critical medical equipment: wheelchairs, mattresses and bath chairs. Methods: The method used to evaluate the disinfection efficacy compared the reduction of contaminants count in the relative light unit using ATP monitoring methods. 30 samples of each of the three types of medical equipment were swabbed pre-disinfection and post-disinfection using the three disinfection methods.Results: The mean log-reduction of disinfection for Accel wipes, Hubscrub, and steam vapor were 1.067, 1.490, and 1.485 respectively. Steam vapor and Hubscrub displayed statistically significantly better disinfection efficacy compared to Accel wipes in terms of log reduction (overall p=0.000002). Conclusion: Hubscrub and steam vapor are better disinfectants compared to Accel wipes in terms of mean log reduction values; however, all three disinfection methods demonstrated effectiveness when cleaning and disinfecting non-critical medical equipment. For critical medical equipment, steam vapor and Hubscrub industrial washing are effective while Accel wipes do not meet the standards of high-level disinfection. As a result, combination usages of all three disinfection methods are recommended at health care facilities based on the categories of the medical equipment.
