BACKGROUND: Dressing rooms attend colonized and infected chronic wounds carriers users and the environment may be contaminated by pathogens present in these lesions during the care. The literature shows the surfaces role corroborating the infection epidemiological chain and have identified low standards of environmental hygiene. This theme has been explored with emphasis on the medium and high complexity. However, it is noted that investments directed to the primary health care are rare. OBJECTIVE: To analyze the effect of environmental surfaces and non-critical health products contamination for Staphylococcus spp. for the safety of dressing rooms workers and users in primary health care. METHODOLOGY: Cross-sectional study of microbiological nature, conducted from July to November 2013 in dressing rooms references in the treatment of chronic wounds of primary health care in Goiás, Brazil. Approved by the Federal University of Goiás Research Ethics Committee (protocol 178/2012). It is began collecting direct observation of ambience processing. Then, have been done the interview, guided by semistructured instrument. The specimens collection from environmental surfaces and noncritical health products was performed using a sterile swab, rubbed on the research site and sent to the laboratory for processing. The microbiological procedures were performed according to standard methodologies. Was used SPSS 19.0 (Statistical Package for Social Sciences for Windows®) and the data were analyzed using descriptive statistical procedures. RESULTS: 38 articles were analyzed, including 32 environmental surfaces and six noncritical health products. It was found at the microbiological testing seven (18.4%) environmental surfaces and products were contaminated by Staphylococcus spp. Eight bacteria were isolated, which of seven (87.5%) were identified as coagulase negative Staphylococcus (CoNS) and one (12.5%), as S. aureus. Staphylococcus spp. were resistant to penicillin G (87.5%) and CoNS, presented a constitutive resistance to macrolidelincosamide-streptogramin B group (MLSBc) (28.6%) and resistance to oxacillin (42.9%). All micro-organisms were resistant to at least one antimicrobial agent. Of the three units investigated, the process of cleaning and disinfection was done by 91.7% of the 12 workers in the study. Nonetheless, was at unconformity with current guidelines. CONCLUSION: The results demonstrate the presence of multidrugresistant pathogens in the ambience of the dressing rooms, which denotes failure in articles processing. These failures may be due to lack of supervision and/or the worker unpreparedness to perform the procedure. Also exposes workers and service users at risk for colonization and eventual infection by these bacterias. This situation benefits cross-contamination and spread of multiresistant microorganisms in primary health care.
