Examining the validity of pressure ulcer risk assessment scales: a replication study.

Risk assessment scales (RASs) intended to identify patients most at risk of developing pressure ulcers have been widely used for many years. Numerous studies have evaluated their predictive validity but potential bias has been inherent in the design of all. To overcome these problems a simulation study was conducted in which clinical nurses were asked to identify the degree of risk experienced by four patients employing the three RASs discussed most frequently in the literature (Norton, Braden and Waterlow Scores).

Establishing the validity of pressure ulcer risk assessment scales: a novel approach using illustrated patient scenarios.

Preventing pressure ulcers is an important nursing goal and over the years a number of risk assessment scales (RASs) have been developed to expedite clinical judgement. The aim of this study was to examine the validity of the three most commonly used RASs compared to nurses' own clinical judgement. Patient simulations were presented to 236 clinical nurses.
