Abstract
Background : Peripheral arterial disease (PAD) leads to significant morbidity and mortality in Diabetic population due to the development of "Diabetic Foot Syndrome". Peripheral Arterial Disease (PAD) is underdiagnosed, undertreated, poorly understood and much more common than thought. Despite its high morbidity and mortality, PAD remains underdiagnosed and undertreated. The ideal screening test for PAD should be inexpensive, non-invasive, accurate, easily administered and universally acceptable. Aims and Objective : To evaluate the effectiveness of Pulse Oximetry and Ankle Brachial Pressure Index (ABPI) in detecting Peripheral Arterial Disease (PAD) among patients with Diabetic Foot Ulcers. Materials and method : A hospital-based cross-sectional study was conducted in the Department of Surgery, Regional Institute of Medical Sciences (RIMS), Imphal, over a period of two years (December 2020 - November 2022). Patients with diabetic foot ulcers were assessed using both Pulse Oximetry and ABPI. Data were analysed using SPSS version 26.0 (IBM Inc.), with a p-value < 0.05 considered statistically significant. Results : Pulse Oximetry demonstrated an accuracy of 92.87%, with sensitivity of 88.88%, specificity of 96.87%, positive predictive value (PPV) of 94.11%, and negative predictive value (NPV) of 93.93%. ABPI showed an accuracy of 91.31%, sensitivity of 88.88%, specificity of 93.75%, PPV of 88.88%, and NPV of 93.75%. Conclusion : Both Pulse Oximetry and ABPI are effective, non-invasive screening tools for diagnosing PAD in diabetic foot ulcer patients. Pulse Oximetry, with its high specificity and ease of use, may serve as a valuable point-of-care diagnostic method, particularly in primary and resource-limited settings. Early identification and intervention can significantly reduce the risk of limb-threatening complications.
