Community-acquired methicillin-resistant Staphylococcus aureus infection in Singapore is usually "healthcare associated".
OBJECTIVE
To assess the frequency of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) infections.


METHODS
A teaching hospital in Singapore.


METHODS
Prospectively collected surveillance data were reviewed during a 1-year period to determine the extent and origin of community-acquired MRSA infections.


RESULTS
Whereas 32% of 383 MRSA infections were detected less than 48 hours after hospital admission and would, by convention, be classified as "community acquired," all but one of these were among patients who had been exposed to outpatient centers including dialysis or chemotherapy clinics, visiting nurses, community hospitals, or all three.


CONCLUSIONS
With health care increasingly being delivered in an outpatient setting, community-acquired MRSA infections are often acquired in hospital-related sites and most may be more accurately described as "healthcare acquired." Infection control measures need to move beyond the traditional paradigm of acute care hospitals to effectively control the spread of resistant pathogens.
