Purpose:This study aimed to clarify differences in contamination status between novices and experts in the one- and two-person methods for removing personal protective equipment(PPE)featuring coverall-type protective clothing. .
Methods:A non-randomized controlled study with 10 nurses was conducted, and the following hypotheses were established:1)The two-person method leads to fewer contaminated sites and shorter undressing time compared with the one-person method. 2)Experts have fewer contaminated sites and shorter undressing time than novices.
Results:A total of 40 cases were collected, including 10 cases of the one-person method (1 pattern) and 30 cases of two-person method (3 patterns). The two-person method led to fewer contaminated sites and required a shorter undressing time compared with the one-person method. Moreover, novices had fewer contaminated sites than experts. Comparison of the contamination status in accordance with the PPE wearing/removal interval revealed that the group with less than 32.5 days of experience (20 cases) had fewer seriously contaminated sites than the group with 32.5 days of experience or longer (20 cases).
Conclusion:The results demonstrated that the two-person method leads to less contamination and allows undressing to be performed in a shorter time, in comparison with the one-person method. Two-person method C, which is performed by the removal assistant from the peeling off of the reinforcement seal of the coverall-type protective clothing to the pulling out of the arms from the sleeves, may be a method that allows undressing to be performed more safely compared with the one-person method. The results suggested that in maintaining safe undressing skills for PPE using coverall-type protective clothing, the possibility that the interval of wearing/removal of PPE featuring coverall-type protective clothing may affect the maintenance of undressing skills should be taken in consideration, along with educational methods for establishing knowledge and integrating practical training.
