Purpose: The Braden Scale is one of the most intensively studied risk assessment scales used in identifying the risk of developing pressuresore. However, not all studies show that the predictive validity of this scale is sufficient. The purpose of this study was to evaluatethe Braden Scale for predicting pressure ulcer development.
Methods: Articles published 1946 and 2013 from periodicals indexed inOvid Medline, Embase, CINAHL, KoreaMed, NDSL and other databases were selected, using the following keywords: ‘pressure ulcer’. The QUADAS-II was applied to assess the internal validity of the diagnostic studies. Selected studies were analyzed using meta-analysiswith MetaDisc 1.4.
Results: Thirty-eight diagnostic studies with high methodological quality, involving 17,934 patients, were included.
Results of the meta-analysis showed that the pooled sensitivity and specificity of the Braden Scale were 0.74 (95% CI: 0.72-0.76), 0.75(95% CI: 0.74-0.76) respectively. However the predictive validity of the Braden Scale has limitation because there was high heterogeneitybetween studies.
Conclusion: The Braden Scale’s predictive validity of risk for pressure ulcer is interpreted as at a moderate level. Howeverthere is a limitation to the interpretation of the results, because of high heterogeneity among the studies.
