Healthcare facilities with high bed occupancy rates, high levels of temporary nursing staff, or low cleanliness scores no longer have significantly higher MRSA rates.

Of course, surgery imposes higher relative risks of perioperative mortality and morbidity e.g. infection including MRSA, bleeding, deep vein thrombosis, lingering anesthesia effects, etc.
