errors due to data entry. Finally, although there was a change in the definition of HA-MRSA bloodstream infection: to be considered an HAI, the MRSA bloodstream infection had to occur within 2 days rather than 4 weeks after discharge. This change occurred in April 2013 during interval 3, after pub- lication of MRSA guidelines. In summary, this study has shown that province-wide
efforts in Québec, following the publication of MRSA guide- lines, resulted in a significant and abrupt decrease in HA- MRSA incidence rates with no temporal change in CLABSI rates. The sustained significant reduction in HA-MRSA inci- dence in the postguideline period suggests a continued impact of the MRSA-specific guidelines years after its publication, along with improved control of both MRSA and other HAIs. These results are encouraging, and future analysis to follow the continuing trend of decreased incidence for CLABSI and HA- MRSA would be helpful in determining whether continuing and new interventions have been helpful to sustain this decrease.
