Room: Hall C
Background: In Dutch hospitals the MRSA 'Search and Destroy' policy is applied successfully. In 2006 a new risk category was added to this control policy. This category includes patients who have professionally direct contact with living pigs or veal calves. Patients who live at a cattle farm are included too. The objective of this study was to determine the number of MRSA positive persons in the new patient group at risk for MRSA carriage, i.e. persons with exposure to pigs or veal calves. Methods: Data of the infection control department was used to retrieve the total number of patients screened in 2006 and 2007 because of exposure to pigs or veal calves after introduction of this risk category in July 2006 and to retrieve the number of MRSA positive patients found in this category. Results: In the last six months of 2006, 57 patients with direct exposure to pigs or calves were screened. Eighteen of them were found to be MRSA positive (32%), i.e. 14/39 (36%) with exposure to pigs and 4/18 (22%) with exposure to calves. In 2007, 122 patients from this risk category were screened. 19 (16%) were found to be positive, i.e. 18/90 (20%) with exposure to pigs and 1/32 (3%) with exposure to calves. Conclusions: Patients with exposure to pigs have an extremely high carriage rate of MRSA. The carriage rate for patients exposed to calves is high, but significantly lower than for those exposed to pigs (p=0.038).
