| Annotation | 1,621 older patients were screened for methicillin resistant Staphylococcus aureus (MRSA) within 24 hours after admission to a geriatric hospital in Geneva, Switzerland. Risk factors associated with previously unknown MRSA were determined in the derivation group, and the resulting risk score was evaluated in the validation cohort using logistic regression analysis. Prevalence of MRSA carriage at admission increased from 7.3% 953/724 patients in 2001 to 8.7% (78/897 patients) in 2003, with a corresponding prevalence of unknown MRSA carriers of 4.6% and 5.8% respectively. Three variables were independently associated with previously unknown MRSA carriage: recent antibiotic treatment, intra-hospital transfer, and admission to hospital in the previous 2 years. In the validation cohort, the probability of MRSA carriage increased across risk scores. The risk score used a simple additive point system to estimate the likelihood of unknown MRSA carriage; it had good accuracy and generalised well in an independent sample of patients. Once validated in a clinical trial, this risk score may be used as a tool to optimise MRSA control. (RH). |
