Subepidermal Moisture Measurements Versus Ultrasound and Visual Skin Assessments for Early Detection of Pressure Injury
Pressure ulcers (PUs) are detected by visual skin assessment (VSA). Evidence suggests ultrasound (US) and subepidermal moisture (SEM) scanner technology can measure tissue damage before it is visible … A pilot study was conducted to evaluate consistency between SEM and US examinations of suspected deep tissue injury (sDTI) … Using an observational, prospective cohort study design, patients >55 years of age were recruited. VSA, SEM, and US assessments were performed daily for a minimum of 3 and maximum of 10 consecutive days following enrollment. US results were considered indicative of sDTI if hypoechoic lesions were present. SEM readings were considered abnormal when ∆ ≥0.6 was noted for at least 2 consecutive days. Boolean analysis was utilized to systematically determine consistency between US and SEM where sDTI was the clinical judgment … read more
