Comment to Question 4
In a prevalence or incidence study, the occurrence of pressure ulcers is the main outcome of the study. At the same time, pressure ulcer assessment is based on a subjective assessment. Therefore, it is important to ensure as far as possible that those who are to determine whether it is a pressure ulcer or not are well trained, and that one or more ways ensure that the assessments are made equally and correctly. Today, there are tools available that can measure reactions in the skin objectively, for example subepidermal moisture measuring, which can also strengthen up the subjective assessment (if the skin is intact). Which level you should focus on depends a lot on the financial and human resources you have and the purpose of the study.
