Emergence of OXA-72-producing Acinetobacter baumannii Belonging to High-Risk Clones (CC15 and CC79) in Different Brazilian States

Abstract

hand hygiene compliance observations and consecutive training efforts is important, given that <10% of all hand disinfections were performed correctly in an observational study by Tschudin-Sutter et al, who observed the 6-step technique. Appropriate hand-surface coverage was reached in only 7.9% of hand hygiene procedures observed by Park et al, despite a high rate of compliance with the correct indications. Shah et al performed a video observation of hand washing. Of 1,081 recordings, 403 (37.3%) were excellent, 521 (48.2%) were acceptable, and 157 (14.5%) were unacceptable. A limitation of our study is the lack of bacterial counts, but the results of Riley et al, who showed no correlation between hand coverage and bacterial counts with a 6-step technique compared to a 3-step approach, had not been published at the time of our experiment. Another limitation is the small number of participants and the experimental setting of this proof-of-principle study. However, we believe that based on our results, the addition of dichotomous subjective quality assessment using the parameters time and skin coverage during live observation by experienced infection control staff is feasible and could be a valuable addition to conventional hand hygiene observation.
