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). These findings were compared with nurses’ clinical judgment rated on a visual analogue scale. The simulations consisted of high-resolution photographs accompanied by case studies of the patients. The nurses’ scores were compared to estimates of risk generated by an expert panel. Nurses’ clinical judgment agreed much more closely with expert opinion than any of the RASs. A replication study was undertaken to confirm these findings. One hundred and fifteen nurses participated in replication. Again the nurses’ clinical judgment matched expert opinion much more closely than the results of the RASs. Replication also drew attention to a number of methodological issues which deserve consideration when using simulation to test the effectiveness of clinical tools and the need to establish adequate measures of external validity whenever use of this method is contemplated.
