Investigation of the effects of clinical parameters on mortality in patients with necrotizing fasciitis

BACKGROUND: Necrotizing fasciitis is a rapidly progressing, potentially fatal soft-tissue infection that spreads through the fascia. Due to the late onset of diagnostic signs during the disease's advanced stage and its rapid progression, it can be challenging to make a prompt diagnosis. However, with a rapid and accurate diagnosis, the progression of the disease can be halted through appropriate early surgical intervention. Even with correct and timely treatment, the mortality rate for necrotizing fasciitis is higher compared to other soft-tissue infections. This study aims to investigate the effects of clinical parameters in patients with necrotizing fasciitis on mortality.METHODS: The study included 37 patients with a necrotizing fasciitis diagnosis between 2009 and 2018. Demographic characteristics of the patients (age, gender, comorbid conditions), duration from diabetes diagnosis if present, blood glucose level at the time of diagnosis, microorganisms isolated from wound cultures, presence of positive blood cultures, administered antibiotic therapy, laboratory risk indicator for necrotizing fasciitis (LRINEC) score at presentation, number and types of surgical procedures performed, length of hospital stay, and mortality rates were retrospectively recorded. Statistical analysis of dependent and independent variables was conducted using t-tests, Mann-Whitney U test, Chi-square test, and Fisher's exact test.RESULTS: Age was found to be an average of 70 in the mortality group, and it is significantly higher compared to the non-mortality group. A high LRINEC score, the presence of comorbidity, and a positive blood culture were also found to be significant in the mortality group. The low number of surgical procedures performed is significantly lower in the mortality group.CONCLUSION: This study highlights the conditions associated with high mortality in patients with necrotizing fasciitis, which is a treatable disease through timely and accurate diagnosis followed by appropriate antibiotic therapy and surgical intervention. It emphasizes the importance of updating the approach for high-risk group patients and aims to provide information that will help lower the threshold for diagnosing necrotizing fasciitis.
