Guidelines for evaluating decubitus ulcer research.
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.
