Prevalence of deep tissue injuries in hospitals and nursing homes: Two cross-sectional studies

Background Deep tissue injuries are severe damages underneath the intact skin caused by long-endured, unrelieved pressure Or shear forces Empirical evidence regarding the magnitude of this health problem is limited Objective Investigation of the prevalence, characteristics of persons affected and identification of the most affected body locations Design Two cross-sectional studies in 2008 and 2009 Settings Nursing homes and hospitals throughout Germany Participants. 6919 (year 2008) and 8451 (year 2009) hospital patients and nursing home residents Methods Trained nurses conducted full skin assessments and collected demographic data based on written data collection forms The Braden scale was used to measure pressure ulcer risk Results Pressure ulcer prevalence including grades 1-4 and deep tissue injuries ranged from 4 3% (95% CI 3 8-4 9) in nursing homes to 7 1% (95% Cl 6 2-8 0) in hospitals Point prevalence rates of deep tissue injuries were 0 4% (95% Cl 0 2-0 5) in hospitals and less than 0 1% in nursing homes In total, 30 persons were affected by 38 deep tissue injuries The mean age was 73.4 and the mean Braden scale sum score was 12 8 The most frequently affected anatomic sites were heels (n = 24) and ischial tuberosities (n = 6) Conclusions Nurses must be aware that deep tissue injuries exist in clinical practice Deep tissue injuries seem to be more common in hospitals than in nursing homes and heels are more prone to this kind of injuries than other body sues. Whenever such a lesion is suspected, optimal pressure relief is required to enable the affected tissue to heal (C) 2009 Elsevier Ltd All rights reserved
