The primary endpoint was to determine the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for a positive MRSA clinical culture. RESULTS. A total of 11391 clinical cultures collected from various anatomical sites were included in this study. The ...
Data analysis was performed using STATA software to estimate pooled sensitivity, specifcity, positive likelihood ratio (PLR) and negative likelihood ratio (NLR), positive predictive value (PPV), and negative predictive value (NPV). Results Ten studies, comprising 39 831 patients, met our inclusion...
P-2090. Using MRSA Nares PCR to Predict MRSA Purulent Skin and Soft Tissue Infections Patients 18 years or older with a diagnosis of purulent cellulitis were included if they had a MRSA nares PCR result and a positive culture for staph ... Greene William,Aslam Sadaf - Open Forum Infectious...
The positive predictive value and negative predictive value were 0.39 (95% CI, 0.25—0.55) and 0.97 (95% CI, 0.91—0.99), respectively. The overall accuracy of the ICPs ruling in or ruling out MRSA nares colonization was 80%. These results suggest that ICPs were able to rule out MRSA ...
MRSA nares PCR for MRSA SSTI had a negative predictive value (NPV) of 66.7% and positive predictive value (PPV) of 96.8%. The sensitivity and specificity of MRSA nares PCR for MRSA SSTI was 62.5% and 97.3% respectively. The NPV of MRSA nares PCR for MRSA SSTI above the waist was 71%...
The MRSA nasal PCR assay is used to detect if a patient's nares are colonized with MRSA. Studies have found that this test has an excellent negative predictive value at ruling out MRSA pneumonia. In practice, there is reluctance to utilize this data to de-escalate vancomycin, possibly ...
