To compare the predictive capacity of the current risk assessment scale for pressure ulcers in intensive care (EVARUCI), translated into Brazilian Portuguese, using the Braden scale.
This cross-sectional study collected prospective data from adult patients in three intensive care units. The receiver operating characteristic (ROC) and precision-recall curve (PR curve) were used to analyse the predictive capacity for pressure injury (PI) using both predictive values and odds ratios (ORs).
The incidence of PIs in the study sample of 324 patients was 14.2%. The area under the ROC curve was 0.807 for EVARUCI and 0.798 for the Braden scale. At a cutoff point of 10 on the EVARUCI scale, sensitivity was 69.6%; specificity 78.4%; positive predictive value 34.8%; and OR 8.3. At a cutoff point of 11 on the Braden scale, sensitivity was 76.1%; specificity 75.9%; positive predictive value 34.3%; and OR 10. The area under the PR curve was 0.396 for the EVARUCI scale and 0.348 for the Braden scale, reflecting a smaller area for both. The F1 score value was 0.476 with 37.5% precision and 65.2% recall for the EVARUCI scale, and 0.473 with 34.3% precision and 76.1% recall for the Braden scale.
The EVARUCI scale predictive capacity was similar to that of the Braden scale. However, the precision of both scales was low for the accurate prediction of patients at risk of developing PIs.
比较经翻译后适用于巴西葡萄牙语的重症监护压力性溃疡风险评估量表（EVARUCI）与 Braden 量表对压力性溃疡（PI）的预测能力。
本横断面研究前瞻性地收集了三个重症监护病房成人患者的数据。使用受试者工作特征（ROC）曲线和精度-召回（PR）曲线分析两种预测值和比值比（OR）对 PI 的预测能力。
324 例研究样本中 PI 的发生率为 14.2%。EVARUCI 的 ROC 曲线下面积为 0.807，Braden 量表为 0.798。在 EVARUCI 量表的截断点为 10 时，灵敏度为 69.6%；特异性 78.4%；阳性预测值 34.8%；OR 8.3。在 Braden 量表的截断点为 11 时，灵敏度为 76.1%；特异性 75.9%；阳性预测值 34.3%；OR 10。EVARUCI 量表的 PR 曲线下面积为 0.396，Braden 量表为 0.348，均较小。EVARUCI 量表的 F1 评分为 0.476，精度为 37.5%，召回率为 65.2%；Braden 量表的 F1 评分为 0.473，精度为 34.3%，召回率为 76.1%。
EVARUCI 量表的预测能力与 Braden 量表相似。然而，两种量表的精度均较低，无法准确预测发生 PI 的高危患者。
