Pressure injury prevention is complex, and rates continue to rise. Checklists reduce human error, improve adherence and standardization with complex processes, focus attention on evidence-based practices derived from clinical practice guidelines and are arranged in a systematic manner to manage the entirety of a patient's risk for preventable outcomes. The original Standardized Pressure Injury Prevention Protocol was created to provide a checklist of pressure injury prevention measures but needed revision and validation. This article describes the revision and content validity testing of the Standardized Pressure Injury Prevention Protocol Checklist 2.0 that took place in 2022. Using the International 2019 Clinical Practice Guideline as a foundation, items were identified/revised, and expert review of the items was obtained. The Standardized Pressure Injury Prevention Protocol 2.0 underwent three rounds of revision by experts from the National Pressure Injury Advisory Panel. A panel of eight national experts completed the content validity survey. Individual item content validity index and total scale content validity index were used to summarize the content validity survey scores. The individual item content validity index scores ranged from 0.5 to 1.0. One item (using a mirror to look at heels) was rated as 0.5, three items were 0.75, 20 items were 0.875 and 23 items were 1.0. The item scoring 0.5 was deleted. Those items scoring 0.75 were revised using the content experts' recommendations. The total scale content validity index was 0.93. The Standardized Pressure Injury Prevention Protocol 2.0 provides a standardized checklist of evidence-based items that operationalize a rigorous clinical practice guideline for the prevention of pressure injuries. Early intervention using a standardized approach and evidence-based checklist that can be integrated into the workflow of the direct-care nurse and provider provides the best opportunity for successful and sustainable pressure injury prevention.
