Factors Affecting Mortality Following Necrotizing Soft-Tissue Infections: Randomized Prospective Study

Area of Science:

• Infectious Diseases
• Surgical Pathology
• Critical Care Medicine

Background:

• Necrotizing soft-tissue infections (NSTIs) present a significant challenge in the Indian subcontinent, characterized by high rates of morbidity and mortality.
• Understanding factors influencing NSTI outcomes is crucial for improving patient care and survival rates.

Purpose of the Study:

• To correlate clinical factors and the Acute Physiology Health and Chronic Health Evaluation (APACHE) II score with mortality in patients diagnosed with NSTI.
• To identify key predictors of survival in NSTI cases.

Main Methods:

• A prospective database of 50 NSTI patients (aged 15-90 years) treated between November 2014 and December 2016 was analyzed.
• Patients were divided into survivors and nonsurvivors, with clinical factors and APACHE II scores compared between groups.

Main Results:

• The study cohort (n=50) had a mean age of 50.8 years, with Fournier's gangrene being the most common NSTI (64%).
• Nonsurvivors exhibited significantly higher body surface area involvement, anemia, metabolic acidosis, elevated serum creatinine, and higher mean APACHE II scores compared to survivors.
• A mortality rate of 32% (16 in-hospital deaths) was observed, with no significant difference in the time to first debridement between groups.

Conclusions:

• The APACHE II score is a significant predictor of mortality in patients with NSTI.
• Prompt diagnosis and aggressive treatment are essential for improving outcomes in NSTI cases.
• Further research with larger sample sizes is recommended to validate these findings.
