Diabetic foot ulcers (DFUs) are a serious and costly complication of diabetes mellitus with a global prevalence of 6.3% and cost of £8,800 per unhealed DFU in the National Health Service. The three main types of DFU are neuropathic, ischemic, and neuroischemic, with an estimated prevalence of 35%, 15%, and 50%, respectively. Because 85% of lower-limb amputations in patients with diabetes are preceded by a DFU, the task of reducing the current and future burden of DFUs on an international level is of crucial importance. Classification of a DFU is an important and complex process with many independent variables that influence the wound severity. Correct classification of a DFU is important to prevent deterioration in the short term and lower-limb amputation in the long term. Both the accuracy of the clinician's interpretation of categorical data from a classification model and grasp of contextual risk factors can refine diagnoses. The term SINBAD is an acronym for six independent variables: site, ischemia, neuropathy, bacterial infection, area, and depth. This system uses comprehensive parameters with strict criteria to facilitate quick and accurate clinical decisions to prevent lower-limb amputation. In addition to providing quantitative measurement, SINBAD also spotlights the multifaceted characteristics of DFUs. By evaluating the validity and reliability of the SINBAD classification system, its applicability for the assessment of DFUs and prevention of lower-limb amputation can be better understood.
糖尿病足溃疡（DFUs）是糖尿病的一种严重且代价高昂的并发症，其全球患病率为 6.3%，在英国国家医疗服务体系中，每个未愈合的 DFU 的治疗费用为 8800 英镑。DFU 的三种主要类型是神经病变性、缺血性和神经缺血性，其估计患病率分别为 35%、15%和 50%。由于糖尿病患者下肢截肢的 85%是由 DFU 引起的，因此减少 DFU 在国际层面上的当前和未来负担的任务至关重要。DFU 的分类是一个重要而复杂的过程，有许多独立的变量会影响伤口的严重程度。正确分类 DFU 对于预防短期恶化和长期下肢截肢至关重要。临床医生对分类模型中分类数据的解释准确性和对上下文风险因素的掌握都可以对诊断进行细化。术语 SINBAD 是六个独立变量的缩写：部位、缺血、神经病变、细菌感染、面积和深度。该系统使用综合参数和严格的标准来促进快速和准确的临床决策，以预防下肢截肢。除了提供定量测量外，SINBAD 还突出了 DFU 的多方面特征。通过评估 SINBAD 分类系统的有效性和可靠性，可以更好地理解其在 DFU 评估和预防下肢截肢方面的适用性。
