ABSTRACT
INTRODUCTION:
The Braden scale is used to assess the risk of patients with pressure injuries (PIs), but there are limitations to the prediction of PI healing. There is a lack of tools for evaluating PI healing and outcome in clinical practice.OBJECTIVE:
The purpose of this study was to examine the ability of the Braden scale to predict the outcome and prognosis of PIs in older patients. MATERIALS ANDMETHODS:
Outcome indicator was the wound healing rate of patients with PIs at discharge. The receiver operating characteristic (ROC) and Hosmer-Lemeshow goodness-of-fit test were used to evaluate the discrimination and calibration.RESULTS:
Completed data were available for 309 patients, 181 of whom (58.6%) were male. The Braden scale had poor discrimination to predict the outcome and prognosis of PIs with an area under the curve (AUC) of 0.63 (95% CI, 0.56-0.70; P = .01). Subgroup analyses showed the Braden scale had low diagnostic value for patients aged over 90 years (AUCROC = 0.56; 95% CI, 0.17-0.96; P = .738), patients with respiratory diseases (AUCROC = 0.51; 95% CI, 0.37-0.65; P = .908), and digestive system diseases (AUCROC = 0.59; 95% CI, 0.42-0.75; P = .342). The level of calibration ability by Hosmer-Lemeshow goodness-of-fit test was acceptable, defined as P >.200 (χ2 = 6.59; P = .473). In patients aged more than 90 years (χ2 = 4.88; P = .431) and female patients (χ2 = 7.03; P = .425), the Braden scale was also fitting. It was not suitable for patients with respiratory diseases (χ2 = 11.35; P = .078).CONCLUSIONS:
The Braden scale had low discrimination for predicting the outcome and prognosis of PIs in older inpatients. The development of a new tool is needed to predict healing in patients with preexisting PIs.
