The aim of this project is to develop, content validate and psychometrically test a tool to measure the knowledge of nurses on skin tear prevention and treatment. A first version of the tool was developed based on expert input (n=32) and the ISTAP best practice recommendations (2018). Face and content validity will be established through a Delphi procedure including experts from the International Skin Tear Advisory Panel (ISTAP). Subsequently, the skin tear knowledge assessment tool will be psychometrically tested (validity of the multiple-choice test items, construct validity, internal consistency, and test-retest reliability) in an international sample of nurses.
The objective of this review was to critically appraise, compare and summarise the quality of the measurement properties of available skin tear classifications. Five skin tear classification systems exist, of which only two have been psychometrically tested. Evidence of very low to moderate quality exists on their measurement properties. To date, the ISTAP classification is the most commonly evaluated system with moderate quality evidence to support its reliability, measurement error and criterion validity. More well-designed, rigorously conducted and adequately reported studies, using representative samples, appropriate statistical methods and direct skin observations, are needed to make confident conclusions.
