Evaluating the Probability of Previously Unknown Carriage of MRSA at Hospital Admission

Probability of previously unrecognized carriage of methicillin-resistant Staphylococcus aureus (MRSA) on admission. Application of the full risk score to the population of 1006 patients included in the case-controlled study. Indicated under the graph are the average probability of previously unrecognized MRSA carriage and the proportion of patients in each probability category (low probability defined as a score of 0 and 1, intermediate probability defined as a score of 2-4, and high probability defined as a score of ≥5).
