PURPOSE: Nosocomial infections caused by methicillin- resistant Staphylococcus aureus (MRSA) are frequently associated with treatment failure, prolonged subsequent treatment and/or hospitalization and additional costs . This study will identify all cases of MRSA colonization and documented infections in the ICU of Casa Grande Medical Center, which is a 187-bed acute care hospital in Pineal county Arizona from 2009 to 2011. Collect the demographics of all the ICU encounters between 2009-2011, including race, gender, age. Assess the efficacy of our isolation techniques which were implemented in 2009. Quantify the amount of vancomycin use in the hospital and compare it to prevalence of MRSA over the year 2009-2011. Evaluate the relationship between MRSA infections and nasal carrier in the ICU.
METHODS: This is a retrospective chart review of all ICU admissions between 2009 to 2011.
RESULTS: There were 2604 ICU encounters identified between 2009-2011. Only 206 encounters were positive for MRSA both carriers and documented infections. Most MRSA were from nasal swaps 86.41%(178) vs cultures 13.59%(28). Only 2.91% (6) were considered to be hospital acquired. MRSA prevalence fluctuated over the years ranging between 9.73%, 5.88%, and 8.15% in years 2009, 2010, and 2011 respectively. The prevalence increased with age and peaked in patients in their fifties reaching 28%, then decreased to 20% in those in their sixties and seventies. Male to female ratio was the same. Most of the MRSA positive patients were Caucasians 67% followed by Hispanics 17.96%, and American Indians 15.53%. Vancomycin consumption has doubled between 2009 and 2011. Prevalence of MRSA nasal carrier among documented MRSA infections is still pending along with the type of infection.
CONCLUSIONS: More studies should be done to determine risk factors and for benefit of the isolation technique.
CLINICAL IMPLICATIONS: More studies should be done to assess the techniques of MRSA decolonization .
