Prevalence and associations of xerosis cutis, incontinence-associated dermatitis, skin tears, pressure ulcers, and intertrigo in aged nursing home residents: A representative prevalence study

Abstract

BackgroundThe number of elderly and care-dependent people is increasing, leading to increased risks of adverse skin conditions. Skin care, including prevention and treatment of vulnerable skin, is an essential part of daily nursing practice in long-term residential settings. For many years, the research focus has been on individual skin problems including xerosis cutis, incontinence-associated dermatitis, skin tears, pressure ulcers, and intertrigo, although people may be affected by several at the same time. ObjectivesAim of the present study was to describe the prevalence and associations of skin conditions relevant to nursing practice in aged nursing home residents. DesignAnalysis of baseline data of a cluster-RCT in long-term residential settings. SettingThe study was conducted in a representative sample of n = 17 nursing homes in the federal state of Berlin, Germany. ParticipantsCare dependent nursing home residents being 65+ years. MethodsA random sample of all eligible nursing homes was drawn. Demographic and health characteristics were collected and head-to-toe skin examinations conducted by dermatologists. Prevalence estimates and intracluster correlation coefficients were calculated, and group comparisons conducted. ResultsThree hundred fourteen residents with a mean age of 85.4 (SD 7.1) years were included. The majority was affected by xerosis cutis (95.9%, 95% CI 93.6 to 97.8), followed by intertrigo 35.0% (95% CI 30.0 to 40.1), incontinence-associated dermatitis 21.0% (95% CI 15.6 to 26.3), skin tears 10.5% (95% CI 7.3 to 13.8), and pressure ulcers 8.0% (95% CI 5.1 to 10.8). In total, more than half of the nursing home residents were affected by two or more skin conditions at the same time. Several associations between skin conditions and mobility, care dependency, or cognitive impairment were observed. There were no associations between xerosis cutis, incontinence-associated dermatitis, skin tears, pressure ulcers or intertrigo. ConclusionsThe adverse skin and tissue conditions xerosis cutis, incontinence-associated dermatitis, skin tears, pressure ulcers and intertrigo are very common in long-term residential settings, placing a high burden on this population. Although care receivers share similar risk factors and may be affected by several skin conditions at the same time, there are no associations indicating separate aetiological pathways.
