A clinical trial of the Braden Scale for Predicting Pressure Sore Risk.

摘要: The purpose of this article was to describe the protocol by which predictive instruments can be tested for validity and evaluate usefulness an instrument predicting pressure sore risk in AICU. Braden Scale Predicting Pressure Sore Risk described. Methods measuring calculating sensitivity, specificity, per cent value positive negative tests were discussed. Sixty consecutively admitted AICU patients who free rated within 24 72 hours after admission. skin condition each patient systematically assessed every 2 days. Twenty-four subjects developed sores during study period. critical cut-off point at could judged formation a score equal or less than 16. sensitivity specificity scale 83 64 cent, respectively. test 61 85 compared favorably with Norton respect sensitivity. tendency overpredict, greater Scale. overpredicted whereas 36 cent. This difference may important clinically if all received additional nursing care protective devices. A number receive unnecessary expensive treatments using
