The classic critique of research is applied to a systematic evaluation of the components of research reports and company literature related to pressure ulcer products and devices. Emphasis is on the need to control variables that influence the findings; some of these are: relief of pressure, nutrition and hydration, comparability of subjects, the Hawthorne Effect and the Pygmalion Effect. Replication of research before adopting products/devices for protocol use is advocated.If the study seems adequate in all the above mentioned categories, the decision for implementation of a new product or device in clinical practice still remains. There may be factors within the institution itself which influence the adoption of new technology. Some of these may be resistance to change, cost of the product/device, or structural hindrances. Critique of research reports or company literature is important before adopting products/devices for clinical use. The more knowledgeable and clinically expert the reader, the greater the possibiities for safe, effective patient care.
