Colonization management of methicillin resistant Staphylococcus aureus in patients and health professional in the haemodialysis unit in a situation of high risk of endemic disease: looking for zero nasal carriers?].

To describe the dynamics of colonization by methicillin resistant Staphylococcus aureus (MRSA) detected in the Haemodialysis Unit (UHD) of the Hospital San Pedro de Alcantara of Caceres due to the detection of catheter-associated infections. Additionally, we attempt to evaluate the effectiveness of preventive strategies introduced. Nasal swab tests were performed in order to detect MRSA colonization in patients and health professionals from August 2008 to January 2009, according to the Consensus GEIH-SEIMC Y SEMPSPH Consensus. An active surveillance was performed with treatment and control of the carriers until negative results were achieved. A consensus document was drawn up in the UHD with registered preventive measures and work systems were reviewed. Prevalence, cumulative incidence, colonization pressure (carrier ratio per day/total patients or experts per day) were calculated. A chi-square test was performed, as well as a Z test for the comparison ratio. The nasal swabs of 54 acute and chronic patients on haemodialysis showed an initial carrier prevalence of 29.6%; cumulative incidence in patients of 42.6%. Nasal swabs of 48 professionals had a cumulative incidence of 39.5%. There was a parallel decrease in colonization pressure in patients and specialists. After five months A smear was performed 5 months later on 40 patients and 26 specialists, which showed no carriers among the patients, and one among the health professionals. We detected a high number of MRSA carriers among patients and Health professionals from the Haemodialysis Unit. Screening and treatment measures were effective for the decolonization of this population. It is important to adopt long-term strategies for active surveillance for the rapid detection of alert situations. Copyright © 2010 Elsevier España, S.L. All rights reserved.
