Brief Summary

Foot ulceration is a risk factor that has been associated with early death in patients with chronic kidney disease. Little is known about the relationship between these risk factors that develop in patients with kidney failure and the onset of lower limb threatening foot ulcers. Diabetes is a major cause of both kidney disease and foot ulceration; however a previous study reported that a significant proportion of kidney failure patients on haemodialysis treatment without a diagnosis of diabetes also had these risk factors that could lead to foot ulceration. The aim of this study will be to identify these risk factors associated with lower limb threatening disease in patients with advanced kidney failure. In addition a robust screening tool will be developed to address the reliability and validity of current screening methods deemed to be gold standard in the assessment of diabetic foot disease in this Chronic Kidney Disease population. It is important to follow the progression of these risk factors as the kidney failure worsens. The study also intends to screen patients as they start dialysis treatment and follow their progress with respect to risk factors known to predispose to foot ulceration over their first year of treatment. The proposed outcome from this study is to develop a strategy to identify patients with kidney failure that are at risk of foot ulceration and intervene at an early point to prevent the life threatening complications associated foot disease.

Outcome Measures

Primary Outcomes (1)

  • The primary outcome of the study is to identify the neurovascular risk factors for foot ulceration as renal function declines, and to develop a suitable foot protection programme for CKD patients.

    4 years

Secondary Outcomes (1)

  • The secondary outcome measure is to identify whether dialysis modality choice influence foot ulcer development and should this be used to inform patient choice of dialysis.

    4 years

Study Arms (2)

CKD Stage 4

eGFR \<30

Other: Foot examination

CKD Stage 5

Receiving Haemodialysis or Peritoneal dialysis therapy

Other: Foot examination

Study Population

It is proposed to identify patients with CKD level 4 (renal function at between 15 and 30% of normal)in the Nephrology clinics at University Hospital of Wales, Cardiff. It is this group of patients that are most at risk of progression of renal disease towards end stage and subsequent need for dialysis. A proportion of the patients will be identified from the pre-dialysis clinics that are due to commence dialysis imminently. It is this group of patients that will used to examine the specific effects of dialysis modality on risk factors for foot ulceration The directorate of Nephrology and Transplantation in Cardiff has 450 haemodialysis patients, 140 peritoneal dialysis (CAPD) patients, and around 400 CKD level 4 patients. Approximately 100 new patients commence dialysis each year of which 35 will start CAPD and the rest haemodialysis.

You may qualify if:

You may not qualify if:

  • CKD stage 1-3 (eGFR \>31)
