AbstractBACKGROUND: American Indians and Alaska Natives (AI/ANs) have had documented outbreaks of methicillin-resistant Staphylococcus aureus (MRSA) infection but, to our knowledge, no studies have examined MRSA infection among this population nationally. We describe MRSA-associated hospitalizations among the approximately 1.6 million AI/ANs who receive care at Indian Health Service health care facilities nationwide. METHODS: We used hospital discharge data from the Indian Health Service National Patient Information Reporting System to determine the rate of MRSA-associated hospitalizations among AI/ANs who used Indian Health Service health care in 1996-2005 and in the comparison periods 1996-1998 and 2003-2005. Hospitalization rates among AI/ANs were examined by year, age group, sex, and region. MRSA-associated diagnoses were also examined. Rate comparisons were performed using Poisson regression analysis. Comparison of rates to those of the general United States population was made for 2003-2005 by means of the Nationwide Inpatient Sample. RESULTS: Between comparison periods, the rate of MRSA-associated hospitalization increased from 4.6 to 50.6 hospitalizations per 100,000 AI/ANs (P<.01 with="" increases="" in="" both="" sexes="" all="" age="" groups="" and="" regions.="" by="" mrsa="" was="" the="" causative="" organism="" for="" majority="" of="" s.="" aureus-associated="" hospitalizations.="" most="" common="" associated="" diagnosis="" skin="" soft-tissue="" infection="" which="" accounted="" mrsa-associated="" diagnoses.="" age-adjusted="" rate="" among="" ai="" hospitalizations="" per="" persons="" compared="" general="" us="" population.="" conclusions:="" have="" increased="" significantly="" served="" indian="" health="" service="" care="" facilities.="" clinicians="" should="" a="" high="" index="" suspicion="" especially="" those="" infection.="">
