Necrotizing soft tissue infection represents a diverse process; the term itself encompasses a continuum ranging from pyoderma to life threatening infections (clostridial gas gangrene with myonecrosis, anaerobic cellulitis, and severe, necrotizing vibrio infections). These can occur in any anatomical area but the commonest site is the extremities. Necrotizing fasciitis is often underestimated because of the lack of specific clinical findings in the initial stages of the disease. The paucity of specific cutaneous signs to distinguish necrotizing fasciitis from other soft tissue infections such as cellulitis makes the diagnosis extremely difficult. The first and most important consideration for an accurate, prompt diagnosis is to have a high index of suspicion. It has been shown by numerous studies in the past that early recognition and surgical intervention at the earliest is the sole factor in preventing the morbidity and mortality in patients with necrotizing fasciitis [1-3]. So a scoring system which is easy to follow and cost effective with high positive and negative predictive value is required. One such scoring system is the LRINEC scoring system devised by Wong et al [4] in 2005 which claims to have a positive predictive value of 92.0% and negative predictive value of 96.0%. The mortality in necrotizing fasciitis is as high as 34%. [5] We evaluated LRINEC scoring system in patients presenting with symptoms and signs suggestive of soft tissue infection that progresses to necrotizing fasciitis in Sri Ramachandra Medical College and Hospital, Porur, Chennai over a period of two years.
