Introduction: We have seen an increase in MRSA isolates in staphylococcal infections for the past forty years and the past twenty years we are seeing an increase in community acquired resistant infections.
Research Question: Identify the trends of community acquired infections across four regions of the United States: East, South, Midwest, and West.
Study Design: Retrospective longitudinal study
Methods: We performed a retrospective study using data obtained within the Cerner electronic medical record that was made available to OSU CHS. The data collected was between the years of 2000 - 2013 using age, sex, and resistance patterns. Data was then analyzed using descriptive statistics in excel.
Results: The total number of Staphylococcal infections 82,500 adult cases and 15,215 pediatric cases. The trend was a decline in total number of Staphylococcus aurous infections in the resistant and susceptible groups from 2000 --2013. However, the percent of resistant infections in the community population has increased over this time with the highest percentage in the Southern region and within pediatric groups.
Conclusions: Although we have seen a decrease in the total number of reported cases of staphylococcal infections from 2000 -- 2013 there has been an increase in the percent of infections that grow out resistant strains of S. aureus. This data shows that the virulence of MRSA is extending from hospitalized patients that we have traditionally thought of as susceptible out into the general population.
