“…As for brushing time, the average brushing time is 2 min [ 85 ], although ANVISA recommends 3 to 5 min. This work agrees with ANVISA because when the brushing time is longer than 2 min, it significantly reduces the colony-forming unit (CFU) [ 83 , 85 , 86 , 87 ]. On the other hand, one of the disadvantages of using a brush is the probability of causing injuries to the surgeon’s skin, increasing the risk of contamination or discomfort, which is why it is suggested not to use this artifact or to the reduction in brushing time or just rubbing the hands with the antisepsis product [ 82 ].…”

Antisepsis of the hands of medical personnel is one of the most important steps in the process of patient care, since direct contact can cause the cross-transfer of potentially pathogenic microorganisms at surgical sites. This study aimed to analyze the prevalence of microorganisms on the hands of 131 surgeons in a university hospital before the surgical procedure. Swabs were collected from each clinician’s hands before and after handwashing. The samples were placed in a transport medium and immediately delivered to a private clinical analysis laboratory from São Luis-Maranhão. The microorganisms were identified by ionization source mass spectrometry and matrix-assisted laser desorption (MALDI-TOF), and antibiotic susceptibility tests (AST) were performed using the Vitek2 and Phoenix-BD automated system. The results showed a high frequency (100%) of microorganisms before handwashing, but after surgical antisepsis, the rate dropped significantly (p < 0.05) to 27.5%. The gram-positive species most detected were Staphylococcus spp. and Micrococcus luteus, representing 83.9%, followed by gram-negative species, Stenotrophomonas maltophilia, Acinetobacter baumanii, Pseudomonas aeruginosa, Pseudomonas gessardi, Pantoea septica, Serratia marcescens, and Burkholderia lata. The effectiveness of hand antisepsis was 72.5%, demonstrating that surgeons’ hands are an important source of microorganisms that can cause infections in hospitalized patients in different care settings.

The results showed a high frequency (100%) of microorganisms before handwashing, but after surgical antisepsis, the rate dropped significantly (p&lt;0.05) to 27.5%. Gram-positive cocci and rods were the most common microbes, followed by gram-negative bacilli species. The effectiveness of hand antisepsis was 72.5%. The ideal would be 100% efficacy, that is, 0% microorganisms in all surgeons. It is logical that the presence of any organism, no matter how infrequent it may be, will always represent a great risk of postoperative infection for any patient.
