Trends in MRSA-associated Pneumonia and Septicemias, 2010-2014

CDDEP researchers calculated rates of Staphylococcus aureus and MRSA-related hospitalizations from 2010 to 2014, for septicemias, pneumonias, and unspecified S. aureus infections, using inpatient records from the National Inpatient Survey (NIS) from the Healthcare Cost and Utilization Project of the Agency for Health Research and Quality (AHRQ). The researchers found that while hospitalization rates for MRSA-

related skin and soft-tissue infections (SSTIs) decreased between 2010 and 2014, rates for more invasive MRSA-related infections, such as sepsis and pneumonia, remained constant. The rate of MRSA septicemias increased from 1.45 to 1.53 per 1,000 hospitalizations and MRSA pneumonia fluctuated between 1.54 to 1.38 per 1,000 hospitalizations.
