What Researchers Did
This retrospective study analyzed data from 45,913 patients in the United States Nationwide Inpatient Sample to determine the effect of hyperbaric oxygen (HBO2) therapy on outcomes in necrotising soft tissue infections (NSTI).
What They Found
Patients with NSTI who received HBO2 therapy had a significantly lower mortality rate (4.5% vs. 9.4%). After adjusting for confounders, HBO2 therapy was associated with a 49% reduced risk of dying (odds ratio 0.49, 95% CI 0.29-0.83), despite leading to higher hospitalization costs (US$52,205 vs. US$45,464) and a longer length of stay (14.3 days vs. 10.7 days).
Canadian Relevance
