IntroductionChronic or non-healing wounds are a serious problem for both the parties involved and the healthcare system. Currently, there are hardly any reliable data on the prevalence of chronic wounds in outpatient care, although this setting is becoming increasingly important. Therefore, the aim of this study was to determine the prevalence of and the factors associated with chronic wounds in clients cared for by home care services. MethodAs part of a cross-sectional study throughout Germany in 2012, a survey was conducted among care recipients provided by home care services. The sample was drawn in a two-step procedure. First, a random sample of home care services was drawn for each federal state, followed by random selection of clients to be interviewed for each service. The aim of the study was to describe the prevalence of chronic wounds and influencing factors such as BMI, age, housing situation, activity and diabetes mellitus. Data collection through questionnaire was carried out by trained nurses. ResultsA total of 144 home care services with 1,296 clients had agreed to participate. With 880 care recipients from 100 home care services finally taking part in the survey, the response rate was 68 %. Of all care recipients examined, 101 had at least one chronic wound; the highest prevalence rates were observed for pressure ulcers (4.6 %) and leg ulcers (4.0 %). Care recipients with diabetes mellitus were more frequently affected by chronic wounds (16.4 %) than non-diabetic recipients (9.5 %). Community-living care recipients (14.1 % chronic wounds; 6.0 % pressure ulcers) and care recipients under the age of 65 (20 % chronic wounds; 9.5 % pressure ulcers) were affected more frequently than care recipients living alone (9.1 % chronic wounds; 3.0 % pressure ulcers) or care recipients older than 65 years (10.5 % chronic wounds; 4.0 % pressure ulcers). In the multivariate calculation, the BMI proved to be the strongest predictor. The prevalence of chronic wounds in the group of obese (BMI>35.3kg/m2) care recipients and those with activity restriction is 44.8 %. ConclusionIn view of the fact that one out of nine care recipients receiving assistance from home care services is affected by at least one non-healing wound, special attention should be paid to the prevention, detection and treatment of chronic wounds. Furthermore, it seems particularly necessary to identify the relevant risk groups in order to be able to initiate adequate and preventive measures at an early stage.
