The Prevalence of Hospitalized Cases of Necrotizing Fasciitis: Anatomical Distribution, Amputations, and In-Hospital Mortality, 2019-2024.
Observational study in Deutsches Arzteblatt international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNecrotizing fasciitis is a life-threatening soft-tissue infection that still carries an in-hospital mortality of 11-30% and an amputation rate of 7-22% despite modern treatment. Only limited population-based data have been available for Germany to date.
methodsWe carried out a retrospective, nationwide descriptive analysis of aggregated administrative routine data from the German DRG system. All hospitalizations with a main diagnosis of necrotizing fasciitis (ICD-10-GM: M72.6) from 2019 to 2024 were included. The prevalence, demographic features, and anatomical distribution of necrotizing fasciitis were studied, as well as the rate of major amputations and in-hospital mortality.
resultsThere were 12 799 hospitalized cases of necrotizing fasciitis over the years of the study. The mean annual prevalence was 2.6 cases per 100 000 people; an upward trend was seen from 2022 onward. Men and patients over age 50 were overrepresented. The most commonly affected sites were the pelvic/femoral region and the lower leg. Major amputations, mainly of a lower limb, were performed in 6.7% to 9.3% of cases. The in-hospital mortality rate averaged 14.9% and remained high throughout the study period. In-hospital mortality largely depended on the anatomic site and was higher with more extensive disease.
conclusionIn Germany, necrotizing fasciitis is associated with a considerable disease burden, high mortality, and high amputation rates. Men and patients over age 50 are at higher risk of developing this disease, and its mortality is highest in patients with extensive disease or involvement of the proximal lower limb. These are the first robust population-based data on necrotizing fasciitis in Germany.
