What Researchers Did
Researchers analyzed a national cohort of 56,527 necrotizing soft-tissue infection (NSTI) admissions from the US Nationwide Inpatient Sample (1998-2010) to determine trends in incidence, patient characteristics, treatment, and outcomes.
What They Found
They identified 56,527 NSTI admissions, with annual cases ranging from 3,800-5,800, peaking in 2004 before decreasing by 2010 (P < .0001). Patient demographics shifted, with increases in the 18-34 (8.8-14.6%) and 50-64 (33.2-43.5%) age groups, Hispanic ethnicity (6.8-10.5%), obesity (8.9-24.6%), and those with over three comorbidities (14.5-39.7%). The percentage of patients needing only one debridement slightly increased from 43.2% to 46.2% (P < .0001).
What This Means for Canadian Patients
While this study is US-based, Canadian patients with NSTI may also experience similar demographic shifts and treatment trends. Early recognition and prompt surgical debridement remain critical for improving outcomes for this severe infection.
Canadian Relevance
This study was conducted using US national data and does not include Canadian patients or healthcare systems.
Study Limitations
As a retrospective database analysis, this study is limited by its reliance on administrative coding and potential for unmeasured confounders.
