Abstract: Aim: This study aims to estimate laboratory risk indicator for necrotizing fasciitis score for patients presenting with cellulitis and the effect of this score in predicting the occurrence of Necrotizing fasciitis in them. Methods: In this Prospective study 120 patients with necrotizing fasciitis were included. It is a Hospital based observational study done at Department of General Surgery and Casualty of Sri Venkateshwaraa Medical College and Research Centre (SVMCH&RC). Sampling Technique: Purposive sampling. Duration of the Study: March 2021 to October 2022- (20 months) PARTICIPANT TIMELINE: 2 weeks to 4 weeks. Results: In our study amongst 120 (100%) patients who took part in the study about 87 patients had secured LRINEC score of < 6 out of which 84 (96.6%) people were diagnosed as cellulitis and 3 (3.4%) persons diagnosed as Necrotizing Fasciitis. 13 people secured LRINEC score between 6-8, out of which 11(84.6%) of them were diagnosed as cellulitis and 2 (15.4%) of them diagnosed as Necrotizing Fasciitis. About 20 of them secured a score of >8 and all 20 of them (100%) were found to be diagnosed with Necrotizing Fasciitis. Conclusion: In Our study the sensitivity of the LRINEC score was 88%, specificity - 88.42%, positive predictive value - 66.66%, negative predictive value - 96.55% and accuracy - 88.33%. To conclude, LRINEC score has shown a better Negative predictive value in identifying the onset of Necrotizing Fasciitis and risk strategization of the patients with severe soft tissue infections. Hence can be used as a reliable laboratory risk indicator for Necrotizing Fasciitis patients with cellulitis along with clinical examination.
