Fournier gangrene: description of 37 cases and analysis of associated health care costs.

BACKGROUND AND OBJECTIVES: Fournier gangrene is a urological emergency associated with a high mortality. It is a necrotizing fasciitis caused by polymicrobial infection originating in the anorectal or genitourinary area. The aim of this study was to analyze the epidemiological and clinical characteristics of Fournier gangrene along with the variables that influence disease course and mortality in patients treated in our department. MATERIAL AND METHODS: We carried out a retrospective study of 37 patients diagnosed with Fournier gangrene between January 2001 and October 2010. RESULTS: All the patients were men, 43.2% had diabetes, and the mean age of the patients was 57.68 years. Statistically significant differences were observed between the age of surviving patients and that of patients who died (55.8 and 69.6 years, respectively). The mean hospital stay was 27.54 days and 32.4% of patients required admission to the intensive care unit. Etiology was unknown in 39.8% of cases. Polymicrobial infection was observed in 59.5% of cases. The mean health care cost associated with a patient diagnosed with Fournier gangrene admitted to intensive care and requiring at least 1 procedure in the operating room was €25,108.67. Mortality was 13.5%. Based on analysis of individual comorbid conditions, only ischemic heart disease displayed a statistically significant association with mortality due to Fournier gangrene; ischemic heart disease was also associated with longer hospital stay. CONCLUSIONS: Fournier gangrene is associated with high mortality despite appropriate early treatment. Although the condition is infrequent, the high associated health care costs suggest that primary and secondary prevention measures should be implemented.

What are the indications for a stoma in Fournier's gangrene?

AIM: This study examined the indications for a stoma in patients with Fournier's gangrene and its impact on outcome. METHOD: Patients with Fournier's gangrene were retrospectively reviewed for indications for a stoma. Patients with and without a stoma were compared, based on demographics, disease severity, surgical therapy, length of hospital stay, clinical outcome and cost. RESULTS: Forty-four patients (median age 57 years, range 28-77 years) were evaluated. Eighteen had a temporary stoma and 26 did not. A stoma was 5 times more likely in males. Patients with Fournier's gangrene originating from an anorectal disorder received a stoma more often than patients with disease originating from an urogenital disorder. Clinical outcomes were similar for patients with or without a stoma. Stoma closure was associated with an extra cost of about $6650 per patient. CONCLUSION: Stoma creation in the management of Fournier's gangrene was needed for selected patients. Having a stoma did not appear to affect outcomes and resulted in a significant increase in cost of care.

The use of vacuum assisted closure therapy in the management of Fournier's gangrene.

BACKGROUND: Vacuum Assisted Closure (VAC; Kinetic Concepts, Inc., San Antonio, TX) has been used to successfully treat a variety of complex wounds. This technique was investigated for use in managing Fournier's gangrene following initial debridement. METHODS: Ten patients with Fournier's gangrene were treated in this study. After initial surgical debridement, 5 were treated using conventional therapy and 5 were treated with VAC at each dressing change. The effectiveness and cost of VAC for this indication were assessed; patient and physician satisfaction were also determined. RESULTS: Conventional and VAC treatment were equally effective in healing the wounds. The total costs of each treatment were similar. With the use of VAC, patients had fewer dressing changes, less pain, fewer skipped meals, and greater mobility. Hands-on treatment time was decreased for physicians using VAC. CONCLUSIONS: VAC therapy is an effective and economical way to manage Fournier's gangrene. Patients and physicians were more satisfied with VAC therapy than with conventional treatment.

Hyperbaric oxygen for the treatment of fournier's gangrene.

PURPOSE: Fournier's gangrene is a necrotizing fasciitis of the genitalia that is associated with high morbidity and mortality. Groups at many institutions have initiated routine adjuvant hyperbaric oxygen (HBO) therapy. We examined whether HBO has made a difference in the morbidity, mortality and costs associated with treating this disease. We also analyzed predictors of extended hospital stay and mortality. MATERIALS AND METHODS: The records of patients with the hospital discharge diagnoses of Fournier's gangrene, necrotizing fasciitis, gangrene of the genitalia and scrotal gangrene from 1993 to 2002 were reviewed. Data concerning clinical presentation characteristics, hospital stay, complications, hospital charges and outcomes, including graft failure and death, were analyzed. RESULTS: A total of 42 patients were identified and followed a median 4.2 years. Of the patients 16 underwent surgical debridement and antibiotic therapy alone, and 26 were treated with HBO plus surgery and antibiotics. Overall disease specific mortality was 21.4%, that is 12.5% in the nonHBO group and 26.9% in the HBO group. Three or more complications occurred in 13% of nonHBO and in 19% of HBO cases, of which the most common was myocardial infarction. The skin graft failure rate was 6% (nonHBO) and 8% (HBO). Physical disability was a statistically significant predictor of extended hospital stay (p <0.01). There was a trend toward a correlation between known coronary artery disease and death (p = 0.2). A statistically significant difference was noted in average daily hospital charges in nonHBO vs HBO cases ($2,552 vs $3,384 daily, p <0.01). CONCLUSIONS: These data do not support routine HBO in the treatment of Fournier's gangrene. There was a trend toward higher morbidity and mortality in the HBO group, suggesting that treatment may have been given to patients who were more ill.

Burn center management of necrotizing soft-tissue surgical infections in unburned patients.

BACKGROUND: Patients with necrotizing soft-tissue infections present great challenges in management from initial presentation through definitive care. Because burn centers concentrate expertise in critical care, wound management, and rehabilitation, we examined the effectiveness of burn center care for patients with necrotizing infections. METHODS: We reviewed our burn center's experience with all patients admitted from 1990 through 1999 with a primary diagnosis of necrotizing fasciitis (NF) or Fournier's gangrene (FG). RESULTS: Fifty-seven patients were identified, 18 with FG and 39 with NF. Patients had a high incidence of preexisting medical problems, including diabetes (37%), obesity defined as greater than 20% above ideal body weight (33%), and hypertension (33%). Seven of 57 (12%) patients died. Patients required a mean of 4.1 operative procedures (range 1 to 15) for definitive wound closure. The mean length of stay (survivors only) was 28.5 days, (range 3 to 70). Although costs increased throughout this period, a formal program of cost-containment resulted in no increase in actual charges per day, from a mean of $4,735 in 1991 to $5,202 in 1999. CONCLUSIONS: Burn centers can provide successful and cost-effective acute care, definitive wound closure, and rehabilitation for patients with NF and FG.
