Outcomes from treatment of necrotizing soft-tissue infections: results from the National Surgical Quality Improvement Program database.
ABSTRACT Necrotizing soft-tissue infections (NSTIs) are a group of uncommon, rapidly progressive, potentially fatal disorders. The National Surgical Quality Improvement Program (NSQIP) Registry was used to determine current data on the incidence, treatment, and outcomes of NSTIs.
There were 688 NSTI cases identified for years 2005 to 2008. Ten control patients for each NSTI patient were also selected. Demographic, laboratory, and outcome data were collected to compare both groups.
Evidence of systemic inflammatory response syndrome (SIRS), sepsis, or septic shock occurred in 83% of NSTI cases. Mortality was 12% for NSTI patients versus 2% for controls. Regression analysis showed that age, emergent surgery, transfer from an outside hospital, sepsis, and several comorbid diseases correlated with mortality but not sex or diabetes. Direct admission was associated with reduced mortality.
NSTIs are seen regularly in academic centers, and their incidence may be increasing. Despite a high incidence of comorbid conditions and frequent presentation with sepsis, mortality is lower than previously reported, reflecting ongoing progress in the treatment of these disorders at NSQIP hospitals.

ABSTRACT: Necrotising soft-tissue infections (NSTIs) are rare conditions with high morbidity and mortality. Patients with NSTIs are often transferred to tertiary hospitals, but the question of whether the potential benefits of highly specialised care outweigh the risks associated with inter-hospital transfers has been raised.Acta Anaesthesiologica Scandinavica 06/2014; · 2.36 Impact Factor

ABSTRACT: Background Necrotizing fasciitis (NF) is a life-threatening soft tissue infection. It is usually caused by Streptococcus pyogenes and other Gram-positive bacteria. Several reports, however, emphasize the importance of Gram-negative rods in this infection. Methods We retrospectively studied all cases of monomicrobial necrotizing fasciitis hospitalized in our center during the years 2002–2012. We compared clinical characteristics and outcomes of patients with Gram-negative versus Gram-positive infection. Results Forty-five cases were reviewed, 19 caused by Gram-negative organisms, 10 of them Escherichia coli, and 26 caused by Gram-positive organisms, 10 of them S. pyogenes. Compared to Gram-positive infections, patients with Gram-negative infections were more likely to have a baseline malignancy (9/19, 47.4%) or to have undergone recent surgery (4/19, 42.3%). The 30-day mortality was higher among Gram-negative infected patients (8/19, 42.1% vs. 8/26, 30.8%). Creatine phosphokinase (CPK) was elevated in a minority of patients with Gram-negative necrotizing fasciitis, and its absolute value was lower than in Gram-positive necrotizing fasciitis. Conclusions In our center, 42% [Au?1] of monomicrobial necrotizing fasciitis cases were found to be caused by Gram-negative organisms, mostly E. coli. These infections usually appeared in immunocompromised or postoperative patients, often presented with normal CPK levels, and were associated with high mortality rates.International Journal of Infectious Diseases 09/2014; · 2.33 Impact Factor
