Does the removal of contact precautions for MRSA and VRE infected patients change health care-associated infection rate?: A systematic review and meta-analysis

Update existing meta-analysis to analyze if discontinuation of contact precautions (CPs) for Methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin resistant Enterococcus (VRE) colonization or infection affects hospital-associated MRSA or VRE infection rates. We conducted a systematic review of 17 studies evaluating discontinuation of CPs for MRSA and VRE. Random-effects and fixed-effects models were used to determine the pooled risk ratios (RR) of preincidence hospital-associated infection rate to postincidence rate. Subgroup analysis was used to assess sources of heterogeneity. No significant difference between rates of hospital-associated MRSA infection before and after stopping the CPs was observed (RR, 0.84; 95% confidence internal [CI], 0.71-1.01; P =.06). An inverse association was observed between discontinuation of CPs and rates of hospital-associated VRE infection (RR, 0.82; 95% CI, 0.72-0.94; P =.005). A subgroup analysis of 6 studies that used chlorhexidine, showed no difference between rates of hospital-associated MRSA infection with discontinuation of CPs (RR, 0.83; 95% CI, 0.69-1.00; P =.05). In 5 studies that did not use chlorhexidine, there was no difference between rates of hospital-associated MRSA infection with discontinuation of CPs (RR, 1.02; 95% CI, 0.55-1.88; P =.95). There was no significant difference in rates of hospital-associated MRSA infection before and after removing CPs. Additionally, there were decreased rates of hospital-associate...
