Abstract
Background
MRSA infection is an important cause of skin and soft tissue, the colonization increases the risk of infection. We estimate the effect of MRSA in health workers of critical areas of a school hospital from second level in Mexico City and its relation of Nosocomial infections.
Methods
Were performed nasal cultured in Health Workers (HW) patients were taken culture according to clinical and a questionnaire was completes. Identification of MRSA was determined by susceptibility to oxacillin, and SSCmec gene was identified the PFGE was performed to look for clonality. Statistical analysis was performed.
Results
Included, 269 patients and 108 of HW, 15% and 12% were MRSA in each group. The relative risk of colonization by MRSA in healthcare workers was 2.77 times higher in intensive care and internal medicine than any other service.The odds of infection with MRSA in hospitalized patients undergoing surgery prior is 41,964 times greater than in patients admitted with other diagnosis. The frequency of SSCmecII was (24/31) in HW and patients. The PFGE indicated the presence of a MRSA clone in both patients and health workers in these critical areas.
Conclusions
The prevalence of carriers of MRSA in staff was similar to that reported in other hospitals of México. There is no direct evidence to validate that colonized health workers increases the risk of nosocomial MRSA infection in patients.
