The assessment of knowledge about PU prevention by using an instrument covering a wide range of relevant topics related to PU prevention can be seen as a strength since it facilitates the detection of bottlenecks. Consequently, educational needs can be highlighted. Despite the tool is easy to administer, the inclusion of 28 items can be seen as a possible disadvantage resulting in an instrument which is too time consuming to complete. For this study the pre-final version of the PUKAT 2.0 was used, given the fact that the validation process was still ongoing at the moment of study start-up. However, this version integrated the recent guidelines and was able to measure the knowledge of nurses and nursing assistants conform these recently published National and International guidelines. Differences between the pre-final version and the final version are minimal and can be found in reformulations of the stem (13 items), reformulations of the response alternatives (15 items) and the exclusion of items (1 in the theme ‘Aetiology’ and 2 in the theme ‘Specific patient groups’).
