To evaluate the accuracy of the defining characteristics of the nursing diagnosis ineffective peripheral tissue perfusion in patients with diabetic foot.
A diagnostic accuracy study with a cross-sectional design was carried out with patients with type 2 diabetes mellitus on outpatient diabetic foot treatment. We evaluated 134 patients with diabetic foot to determine the accuracy of the defining characteristics of ineffective peripheral tissue perfusion. A latent class model with random effects was used to establish the sensitivity and specificity of the defining characteristics assessed.
Ineffective peripheral tissue perfusion was present in 83.79% of the patients. The defining characteristics color does not return to lowered limb after 1-minute leg elevation and edema had high sensitivity (0.8370 and 0.7213) and specificity (0.9991 and 0.9995).
The defining characteristics color does not return to lowered limb after 1-minute leg elevation and edema are good clinical indicators that can be used for screening and confirming ineffective peripheral tissue perfusion in patients with diabetic foot.
评估糖尿病足患者外周组织灌注无效护理诊断的定义特征的准确性。
这是一项横断面设计的诊断准确性研究，纳入了接受 2 型糖尿病门诊足部治疗的患者。我们评估了 134 例糖尿病足患者，以确定外周组织灌注无效的定义特征的准确性。使用具有随机效应的潜在类别模型来确定评估的定义特征的灵敏度和特异性。
83.79%的患者存在外周组织灌注无效。特征颜色在 1 分钟腿部抬高后未恢复到下肢和水肿具有较高的灵敏度（0.8370 和 0.7213）和特异性（0.9991 和 0.9995）。
特征颜色在 1 分钟腿部抬高后未恢复到下肢和水肿是可用于筛查和确认糖尿病足患者外周组织灌注无效的良好临床指标。
