Better Management of OPAT Can Reduce Readmissions

Clin Infect Dis; ePub 2018 Sep 21; Shah, et al

Infectious disease (ID) consultation among privately insured patients aged <65 years during outpatient parenteral antimicrobial therapy (OPAT) is associated with significant reductions in the rate of emergency department (ED) admission and 30-day readmission, a recent study found. Researchers analyzed inpatient acute-care stays in 2013 and 2014 that were followed by OPAT. Patients who received outpatient ID intervention (ID-led OPAT) were matched 1:1 with those who did not (Other OPAT). They found:

  • 8,200 observations were included in the final analytic sample.
  • Soft-tissue infection and osteomyelitis were the most common infections in the index event, each affecting >40% of individuals.
  • Those with ID-led OPAT had lower odds of ED admission or hospitalization over 30 days, relative to those with Other OPAT.
  • Accumulated healthcare payments totaled $1,488 less among those with ID-led OPAT.
