Oncology hospital health workers colonized by multi-drug resistant microorganisms

Cross-sectional study conducted with health workers of an Oncology Hospital between 02/2009 and 12/2010. The objective was to characterize the profile of workers colonized by multi-drug resistant microorganisms and identity their adherence to Hand Washing and Personal Protective Equipment (PPE). The subjects were interviewed, a sample of saliva was collected and microbiological analyses were performed. Data were treated using SPSS registered /19.0. All ethical aspects were considered (protocol040/08). A total of 148 workers were colonized, 29.7% by multi-drug resistant microorganisms. Most (75%) worked 40 weekly hours or more. It wasn't found any relationship between the professional category and being colonized, or between being colonized and types of work contracts. All subjects reported washing hands; 97.8% frequently. Regarding PPE, 91% reported adherence. Infection control and prevention measures at the studied institution must be improved, which includes an active microbiological surveillance of workers.
