Decreasing Incidence of SSTIs at US EDs

Clin Infect Dis; ePub 2018 Jun 15; Morgan, et al

There was a decline in skin and soft tissue infections (SSTIs) at 86 US emergency departments (EDs) from 2009-2014, noted as an epidemiologic shift from the increase in STTIs after 2000, a recent study found. Data were obtained for patient encounters at all academic medical center EDs affiliated with the Vizient clinical data warehouse who had an SSTI-associated ICD-9 code between January 1, 2009 and December 31, 2014. The rate was calculated per 1,000 ED encounters by year and stratified by SSTI, HIV, and both; and by age group, race, payer type, and region of care. Researchers found:

  • In 2009-2014, 47,317 HIV-associated and 820,440 SSTI-associated encounters were recorded among 25,239,781 ED patient encounters.
  • The rate of SSTIs among all patients as well as among those with HIV decreased 8% and 14.6%, respectively.
  • The SSTI incidence overall decreased from 32.0 to 29.7/1,000 ED encounters between 2009 and 2014.
  • HIV-infected patients had a significantly higher rate of SSTIs.
