What Researchers Did
Researchers looked at which factors were linked to death and amputation in patients with a serious flesh-eating soft tissue infection called necrotizing soft tissue infection (NSTI).
What They Found
This retrospective study of 50 patients treated for NSTI between 2021 and 2024 found a mortality rate of 20% (10 patients) and an amputation rate of 60% (30 patients). Diabetes was significantly related to amputation, and both length of hospital stay and length of ICU stay were significantly associated with mortality. The LRINEC score, chronic renal failure, sepsis, hyperbaric oxygen therapy (HBOT), smoking, and the timing of surgical intervention were all examined but were not significantly associated with amputation rates. The most common microorganism isolated was Streptococcus pyogenes.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This is a retrospective, single-center study of only 50 patients with no control group, which limits how confidently these associations can be generalized to other populations.
