Risk predictive value of two kinds of scales on skin postocclusive reactive hyperemiain ICU patients

Abstract

Objective To explore the predictive value of Cubbin & Jackson Scale and Braden scale on skin postocclusive reactive hyperemia in intensive care unit (ICU) patients. Methods From June 2016 to June 2018, we selected 150 surgical ICU at Xuanwu Hospital of Capital Medical University as subjects by convenient sampling. The Braden Scale and Cubbin & Jackson Scale were used to evaluate the risk of skin postocclusive reactive hyperemia in ICU within 14 days. We compared the sensitivity, specificity, positive predictive value and negative predictive value of two kinds of scale based on the best critical values. The areas under the receiver operating characteristic (ROC) curve were used to compare the predictive value for reactive hyperemia of two kinds of scale. Results Taking the concept of reactive hyperemia in Science and practice of pressure ulcer management as the gold standard, there were 46 (30.6%, 46/150) cases with reactive hyperemia and 6 (13.0%, 6/46) cases with pressure ulcer. The best critical values of Cubbin & Jackson scale and Braden scale were 29 and 13 respectively. The sensitivity, specificity, positive predictive value, negative predictive value and areas under the ROC of Cubbin & Jackson Scale and Braden Scale were 90%, 63%, 68%, 97%, 0.875 and 96%, 43%, 35%, 94%, 0.537 respectively. Conclusions The sensitivity in reactive hyperemia of Cubbin & Jackson Scale is lower, but the the holistic balance is higher than that of Braden scale which shows that the predictive value is higher than that of Braden.
