Taiwan is known to have the greatest number of dialysis patients total compared to other countries. Also, unlike other countries, National Health Insurance pays 100 percent of the cost of dialysis. Motivated by the above two facts, the government of Taiwan and researchers have conducted many studies with the aims of increasing the quality of dialysis service and reducing the corresponding cost. One recent successful research regarding dialysis comes from the Industrial Technology Research Institute (ITRI) in Taiwan, which has created a portable measuring device for arteriovenous fistulas and vascular stenoses (ITRI-PASD). The device tries to measure whether a patient’s vascular stenosis is within the safety levels required before any dialysis treatment. This research focuses on increasing the sensitivity and specificity of the above-mentioned ITRI-PASD, where sensitivity is sometimes called the true positive rate and the specificity is called the true negative rate. Results show that the proposed approach has both sensitivity and specificity beyond 98%.
