Sacdal JPA, Cheon E, Stilwell AM, Acquisto NM, Treu CN. Oritavancin versus oral antibiotics for treatment of skin and skin structure infections in the emergency department. Am J Emerg Med. 2022 Jul 8:S0735-6757(22)00448-X. doi: 10.1016/j.ajem.2022.07.013. Epub ahead of print.
- To compare adult ED patients gram-positive SSTI treated with oritavancin to those who required IV antibiotics/hospitalization but left against medical advice (AMA) and therefore received oral antibiotics.
- Before/After observational study
STUDY INTERVENTION & COMPARISON
- Oritavancin, n=51
- Oral Antibiotics, n=31
- ED revisit
- Oritavancin 16% vs. 36% oral antibiotics (p = 0.06)
- Hospitalization for worsening infection
- Oritavancin 12% vs. 26% oral antibiotics (p = 0.13)
- Secondary Outcomes
- There was no difference in additional antibiotics within 30 days (both groups 35%).
- Mean ED LOS was longer for oritavancin patients, 529 ± 126 vs. 448 ± 231 min (p = 0.04).
- ED revisit
- Single-dose oritavancinwas associated with clinically, but not statistically, significant reductions in 30-day ED visits and hospitalizations for worsening infection compared to patients treated with OAB because of refusing hospitalization/leaving AMA. Additional studies in high acuity settings with larger sample sizes are needed to identify the optimal population for oritavancin.
