AIMS: Fournier's gangrene (FG) is the necrotizing fasciitis of the perineum and genital area and presents a high mortality rate.
The aim was to assess prognostic factors for mortality, create a new mortality predictive scale and compare it with previously published scales in patients diagnosed with FG in our Emergency Department.
METHODS: Retrospective analysis study between 1998 and 2012.
RESULTS: Of the 59 patients, 44 survived (74%) (S) and 15 died (26%) (D). Significant differences were found in peripheral vasculopathy (S 5 [11%]; D 6 [40%]; P=.023), hemoglobin (S 13; D 11; P=.014), hematocrit (S 37; D 31.4; P=.009), white blood cells (S 17,400; D 23,800; P=.023), serum urea (S 58; D 102; P< .001), creatinine (S 1.1; D 1.9; P=.032), potassium (S 3.7; D 4.4; P=.012) and alkaline phosphatase (S 92; D 133; P=.014). Predictive scores: Charlson index (S 1; D 4; P=.013), severe sepsis criteria (S 16 [36%]; D 13 [86%]; P=.001), Fournier's gangrene severity index score (FGSIS) (S 4; D 7; P=.002) and Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; D 13; P=.004). Independent predictive factors were peripheral vasculopathy, serum potassium and severe sepsis criteria, and a model was created with an area under the ROC curve of 0.850 (0.760-0.973), higher than FGSIS (0.746 [0.601-0.981]) and UFGSI (0.760 [0.617-0.904]).
CONCLUSIONS: FG showed a high mortality rate. Independent predictive factors were peripheral vasculopathy, potassium and severe sepsis criteria creating a predictive model that performed better than those previously described.
