| Summary: | Epidemiologic analyses in routine care of chronic wounds are scarce, and published studies show wide variations. This study analyzes the population-based prevalence and incidence of chronic wounds in Germany. Secondary analyses of data from a German statutory health insurance with about 9 million insured persons were examined (2010 to 2012). Internal diagnostic validations were used to control for different inclusion criteria. In 2012, 1.04% (95% CI 1.03-1.05) of insured patients had a wound diagnosis, including 0.70% with leg ulcers and 0.27% with diabetic ulcers. Wound treatment was received by 0.43% (0.43-0.44) of patients. Prevalence and incidence increased over 3 years. Extrapolated to the German population, there were 786,407 prevalent and 196,602 incident chronic wounds, including 326,334/172,026 patients who underwent wound-relevant treatment in 2012. There is an annually increasing frequency of chronic wounds in Germany. Chronic wound epidemiology is sensitive to wound treatment as a filter criterion.
