Community based prevalence for diabetes related foot disease (DRFD) has been poorly quantified in Australian populations. The aim of this study was to develop and validate a survey tool to facilitate collection of community based prevalence data for individuals with DRFD via telephone interview.
Agreed components of DRFD were identified through an electronic literature search. Expert feedback and feedback from a population based construction sample were sought on the initial draft. Survey reliability was tested using a cohort recruited through a general practice, a hospital outpatient clinic and an outpatient podiatry clinic. Level of agreement between survey findings and either medical record or clinical assessment was evaluated.
The Questionnaire for Diabetes Related Foot Disease (Q-DFD) comprised 12 questions aimed at determining presence of peripheral sensory neuropathy (PN) and peripheral vascular disease (PVD), based on self report of symptoms and/or clinical history, and self report of foot ulceration, amputation and foot deformity. Survey results for 38 from 46 participants demonstrated agreement with either clinical assessment or medical record (kappa 0.65, sensitivity 89.0%, and specificity 77.8%). Correlation for individual survey components was moderate to excellent. Inter and intrarater reliability and test re-test reliability was moderate to high for all survey domains.
The development of the Q-DFD provides an opportunity for ongoing collection of prevalence estimates for DRFD across Australia.
澳大利亚人群中对糖尿病相关足部疾病（DRFD）的社区患病率缺乏定量研究。本研究旨在开发和验证一种调查工具，以便通过电话访谈收集 DRFD 患者的社区患病率数据。
通过电子文献检索确定 DRFD 的公认组成部分。对初始草案征求了专家意见和基于人群的构建样本的反馈。通过普通诊所、医院门诊诊所和门诊足病诊所招募的队列测试了调查的可靠性。评估了调查结果与病历或临床评估之间的一致性。
问卷包括 12 个问题，旨在根据症状和/或临床病史的自我报告以及足部溃疡、截肢和足部畸形的自我报告，确定周围感觉神经病变（PN）和周围血管疾病（PVD）的存在。46 名参与者中的 38 名的调查结果与临床评估或病历一致（kappa 值为 0.65，敏感性为 89.0%，特异性为 77.8%）。个别调查组成部分之间的相关性为中度至极好。所有调查领域的组内和组间可靠性以及测试重测可靠性均为中度至高度。
Q-DFD 的开发为在澳大利亚持续收集 DRFD 的患病率估计提供了机会。
