Background: Breaches in reprocessing reusable instrument through high level disinfection (HLD) can result in transmission of infections. Cleaning followed by high level disinfection performed by qualified medical staff ensures that there is prevention of disease transmission among patients. Qualification of medical staff to reprocess the instruments includes education on the transport, cleaning, disinfection, and storage of the semi-critical instrument according to manufactures instructions.


We created a competency program that included a didactic component and hands on training to evaluate knowledge about high-level disinfection in 13 outpatient clinics. Sixteen specific questions regarding various key HLD topics including: quality control, preparation, expiration, policy knowledge, definition, instructions for use, and safety were used to test knowledge. Fifty one trainees completed a pre and posttest to evaluate efficacy of the competency program.


The outlying lowest scored questions in the pre-test were about quality control and expiration. Test strip solution preparation (40%), expiration (37%), frequency of testing the test strip bottle (54%), and the time required before test strips can be read (13%) were frequently missed questions. Knowledge gaps associated with the disinfectant were disinfectant expiration once opened (33%), appropriate disinfectant temperature (31%) and how often the solution needs to checked (44%. In the post test the two frequently missed questions were about appropriate disinfectant temperature (85%) and the frequency of testing the test strip bottle (77%). After the training the overall mean score improved from 61% on the pretest to 94% on the posttest (p value <0.0001) CI (95% CI: 28.0, 37).Overall HLD practices were 62% pre training and improved to 94% post training.


Our evaluation indicates pre competency training participants were not proficient and had knowledge gaps. There was a significant improvement in scores indicating the competency program was effective in closing high level disinfection knowledge gaps. More outcome data is required to fully assess the impact of the program on reprocessing practices.
