For chronic dialysis patients, the effect of preventing major amputation and its cost-effectiveness of guidance/management fee for peripheral arterial disease of lower limb will be evaluated.
Others
Using a database consisting of receipts and DPCs, we will compare the rate of major amputations between patients with chronic dialysis patients who have calculated guidance/management fee for peripheral arterial disease of lower limb and those who have not.
Major amputation rate
1.Cost-effectiveness of guidance/management fee for peripheral arterial disease
2. Patients rate undergoing major amputation, minor amputation, EVT and bypass surgery
3. Major amputation rate with and without minor amputation
4. Major amputation rate with or without ischemic limbs
5. Major amputation rate in patients with a history of major amputations
6. Major amputation rate in patients undergoing renal rehabilitation
7.Major amputation rate in patients with chronic renal failure due to diabetic nephropathy
8.Major amputation rate in patients with chronic renal failure due to nephrosclerosis
9.Major amputation rate in patients with chronic renal failure due to glomerulonephritis

Index date(t0) is March 2016, when guidance/management fee for peripheral arterial disease of lower limb can be calculated. Patients who meet the following conditions starting from Index Date (t0).
(1) Patient receiving dialysis at t0
(2) Patients aged 20 to 75 years at t0
(1) Patients who have undergone major amputation due to trauma or malignant tumors within the evaluation period
(2) Patients with a history of malignant tumors (Treatment for malignant tumors has been performed before t0)
(3) Patients who started to calculate the guidance/management fee for peripheral arterial disease of lower limb during the evaluation period
(4) Dementia patients(Dementia treatment has been performed before t0)
(5) Patients with mental disease(mental disease treatment has been performed before t0)
(6) Patients who underwent kidney transplantation during the study period (April 2012-June 2019)
(7) Patients with collagen disease, vasculitis, etc. (including rare diseases) (collagen disease, vasculitis, etc. treatment have been performed before t0)
(8) Patients who started dialysis from January to March 2016
(9) Patients using a auxiliary artificial heart (using a auxiliary artificial heart before t0)
(10) Patients undergoing EVT or bypass surgery (undergoing EVT or bypass surgery before t0)

This study is a retrospective cohort study utilizing the medical information database collected from April 2012 to June 2019. Patients undergoing chronic dialysis therapy are identified, and the rate of major amputation and cost-effectiveness are calculated and evaluated between the two groups of patients who have calculated guidance/management fee for peripheral arterial disease of the lower limb and those who have not.
