Necrotizing fasciitis: A highly fatal infection

Area of Science:

• Infectious Diseases
• Surgical Pathology
• Public Health Economics

Background:

• Necrotizing fasciitis (NF) is a rapidly progressive bacterial infection affecting all layers of the skin and superficial fascia.
• Prompt diagnosis and aggressive surgical debridement are critical for patient survival.
• Understanding the economic and mortality impact of NF is essential for public health strategies.

Purpose of the Study:

• To retrospectively analyze the clinical characteristics, management, and outcomes of patients with necrotizing fasciitis.
• To compare the hospitalization costs and mortality rates between different types of NF (Type I and Type II).
• To evaluate the impact of management speed on mortality in necrotizing fasciitis patients.

Main Methods:

• Retrospective analysis of 65 patients with necrotizing fasciitis managed between January 2011 and May 2021.
• Collection of demographic data, biological parameters, bacterial types, hospitalization costs, and mortality rates.
• Statistical analysis using Student's t-test and Chi-squared test (P<0.05) to compare outcomes.

Main Results:

• The average patient age was 68.8 years, with a mean length of stay of 32.4 days and an average cost of €79,305.
• Lower limbs (57%) and perineum (35%) were the most common locations for NF.
• Mortality rates significantly differed between NF types (P=0.003), but not between management speeds (P=0.45). Hospitalization costs were comparable across types (P=0.21).

Conclusions:

• Early diagnosis, surgical debridement, and antibiotic therapy are crucial for managing necrotizing fasciitis.
• Necrotizing fasciitis imposes a significant societal cost, highlighting the importance of preventing risk factors.
• A comprehensive patient management approach is necessary to improve survival rates in necrotizing fasciitis.
