Recent data have shown that a negative MRSA nares screen by PCR has a negative predictive value of 98%. This implies that the absence of colonization can significantly reduce empiric vancomycin utilization. This study aimed to determine the utilization of MRSA nares screening on patients receiving ...
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...
Provided that there is effi-cient DNA preparation from the swab, a well functioningPCR protocol and a solid evaluation performed on a rep-resentative spectrum of clinical specimens, this methodnormally can achieve a negative predictive value of morethan 99% for the direct detection of MRSA (mecA...
Evaluation of the timing of MRSA PCR nasal screening: How long can a negative assay be used to rule out MRSA-positive respiratory cultures? Purpose Previous studies indicate that the polymerase chain reaction (PCR) nasal assay for methicillin-resistant Staphylococcus aureus (MRSA) has a consist.....
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 screening has excellent negative predictive value for MRSA pneumonia and results faster than culture. We sought to decrease vancomycin overuse by identifying patients at low risk for MRSA pneumonia using rapid polymerase chain reaction (PCR) as part of an automated pharmacy-based ...
The primary outcome was to determine the negative predictive value (NPV) of the MRSA nasal screen for MRSA pneumonia. Secondary outcomes included sensitivity, specificity, positive predictive value (PPV) of the MRSA nasal screen and prevalence of MRSA pneumonia. Results: Of 98 patients with AML ...
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 ...
The Decision Tree analyses have shown high sensitivity (96.5%), specificity (73.0%), positive predictive value (90.7%), and negative predictive value (88.5%) when identifying specific peaks for the discrimination of S. aureus SCCmec types II, III and IV [33]. Although these analyses are pote...
