AIMS To assess the accuracy of once-daily foot temperature monitoring for predicting foot ulceration in diabetic patients with recent wounds and partial foot amputation, complications previously perceived as challenging. METHODS We completed a planned analysis of existing data from a recent study in 129 participants with a previously-healed diabetic foot ulcer. We considered four cohorts: all participants, participants with partial foot amputation, participants with a recent wound, and participants without partial foot amputation and without a recent wound. We reported the prediction specificity, lead time, and annualized alert burden in each cohort at maximum sensitivity. We assessed the two potentially challenging cohorts for non-inferior accuracy relative to the control cohort using Delong's method. RESULTS We report non-inferior predictive accuracy in each of the two potentially-challenging cohorts relative to the control cohort (⍺ < 0.05). The alert lead time was similar across these cohorts, ranging from 33 to 42 days. CONCLUSIONS Once-daily foot temperature monitoring is no less accurate for predicting foot ulceration in those with recent wounds and partial foot amputations than in those without these complications. These results support expanded practice of once-daily foot temperature monitoring, which may result in improved patient outcomes and reduced healthcare resource utilization.

足部温度监测垫用于预测近期有伤口或部分截肢的糖尿病性足溃疡的准确性。

目的为了评估每天一次的脚部温度监测的准确性，以预测患有近期伤口和部分截肢的糖尿病患者的足部溃疡，以前认为并发症具有挑战性。方法我们完成了一项对129例先前治愈的糖尿病足溃疡患者的近期研究的现有数据的计划分析。我们考虑了四个队列：所有参与者，部分截肢的参与者，最近受伤的参与者以及没有部分截肢和最近的创伤的参与者。我们以最大的敏感性报告了每个队列的预测特异性，提前期和年度警报负担。我们使用Delong方法评估了两个相对潜在的具有挑战性的队列相对于对照队列的准确性。结果我们报告了两个潜在挑战人群中相对于对照人群的非劣预测准确性（⍺<0.05）。这些队列的预警提前期相似，范围为33至42天。结论每天一次的脚部温度监测与没有这些并发症的人相比，在预测近期有伤口和部分截肢的人的足溃疡方面，准确度不低。这些结果支持每天进行一次脚部温度监测的扩展实践，这可能会改善患者的预后并降低医疗资源的利用率。结论每天一次的脚部温度监测与没有这些并发症的人相比，在预测近期有伤口和部分截肢的人的足溃疡方面，准确度不低。这些结果支持每天进行一次脚部温度监测的扩展实践，这可能会改善患者的预后并降低医疗资源的利用率。结论每天一次的脚部温度监测与没有这些并发症的人相比，在预测近期有伤口和部分截肢的人的足溃疡中的准确性并不差。这些结果支持每天进行一次脚部温度监测的扩展实践，这可能会改善患者的预后并降低医疗资源的利用率。
