A systematic and psychometric review of tests measuring nurses' wound care knowledge

Wound care is an important realm of nurses' clinical responsibilities, and a broad knowledge and range of skills are needed to perform efficient and safe patient care. Nurses' knowledge on this matter can be measured using knowledge tests. This study aims to identify, define, and analyse the knowledge tests developed for the measurement of nurses' wound care knowledge, and to evaluate the psychometric properties of the tests. This study was a systematic literature review. A total of 52 studies and 18 instruments were found. Of the 18 instruments, only 5 had been used more than once and were successful in a psychometric evaluation. These five instruments were analysed on the basis of their psychometric properties by using Zwakhalen et al.'s (2006) psychometric testing framework. According to the analysis, the Pressure Ulcer Knowledge Test (PUKT) and the Pressure Ulcer Knowledge Assessment Tool (PUKAT) were the most valid and reliable instruments for measuring nurses' wound care knowledge. Most of the instruments identified and analysed focused on pressure ulcers, indicating that future instruments could focus more on other types of wounds or on wound care in general in order to receive a broader understanding of nurses' wound care knowledge.
