Abstract :
Background: The purpose of this study was to present a scientific reason for pressure ulcer risk scales: Cubbin& Jack-son modified Braden, Norton, and Waterlow, as a nursing diagnosis tool by utilizing predictive validity of pressure sores.
Methods: Articles published between 1966 and 2013 from periodicals indexed in the Ovid Medline, Embase, CI-NAHL, KoreaMed, NDSL, and other databases were selected using the key word “pressure ulcer”. QUADAS-Ⅱ was applied for assessment for internal validity of the diagnostic studies. Selected studies were analyzed using meta-analysis with MetaDisc 1.4.
Results: Seventeen diagnostic studies with high methodological quality, involving 5,185 patients, were included. In the results of the meta-analysis, sROC AUC of Braden, Norton, and Waterflow scale was over 0.7, showing moderate predictive validity, but they have limited interpretation due to significant differences between studies. In addition, Wa-terlow scale is insufficient as a screening tool owing to low sensitivity compared with other scales.
Conclusion: The contemporary pressure ulcer risk scale is not suitable for uninform practice on patients under stand-ardized criteria. Therefore, in order to provide more effective nursing care for bedsores, a new or modified pressure ulcer risk scale should be developed upon strength and weaknesses of existing tools.
