A knowledge test on pressure injury in adult intensive care patients: Development, validation, and item analysis.

Background: Pressure injuries are a major problem in critically ill patients, but both students' and intensive care nurses' knowledge about these injuries leaves room for improvement. As no knowledge test is currently available that focuses on pressure injuries in adult intensive care patients, we aimed to develop such tool, establish the content validity, and perform item analysis using Classical test theory.

Methods: Test development followed established multiple-choice question-writing guidelines.
