In this meta-analysis, researchers attempted to compare different MRSA screening methods (active-rapid by PCR, active-usual by culture, or no active screening), to outcomes (incidence of MRSA acquisition, MRSA blood stream infections, or MRSA surgical site infections). They found PCR versus culture screening did not affect rates of MRSA acquisition, but that PCR versus no screening significantly reduced MRSA blood stream infections. This implies that some screening is better than no screening, but that the type of screening (PCR vs culture) is less important (abstract).
