A foot care program for diabetic unilateral lower-limb amputees

Area of Science:

• Podiatry
• Vascular Surgery
• Diabetology

Background:

• Diabetic unilateral lower-limb amputees are at high risk for contralateral limb amputation.
• Existing foot care programs aim to prevent secondary amputations but their efficacy requires evaluation.
• Peripheral vascular disease (PVD) and neuropathy are common complications impacting lower limb health in diabetics.

Purpose of the Study:

• To evaluate the effectiveness of a specialized foot care program in preventing a second amputation among diabetic unilateral lower-limb amputees.
• To assess the prevalence and impact of peripheral vascular disease and neuropathy in this patient cohort.
• To identify risk factors associated with contralateral limb amputation.

Main Methods:

• A cohort of 143 diabetic unilateral lower-limb amputees receiving prosthetic care was studied.
• Comprehensive assessments included peripheral vascular evaluation (ankle-brachial pressure index, skin oxygen levels), nerve assessment, and foot care knowledge.
• Patients were followed to determine rates of contralateral amputation over a 2-year period.

Main Results:

• The specialist foot care program did not significantly reduce the rate of contralateral amputation (15.4% vs. 14% in a matched control group).
• Bilateral amputees exhibited significantly lower mean ankle-brachial pressure index (a marker of PVD) compared to unilateral amputees.
• No significant differences were found in foot care knowledge or neuropathy scores between patients who underwent a second amputation and those who did not.

Conclusions:

• Peripheral vascular disease is more strongly associated with bilateral amputations in diabetic patients than neuropathy or foot care knowledge.
• Current preventative foot care programs for diabetic unilateral amputees need enhancement.
• Greater emphasis on peripheral vascular assessment and timely intervention strategies is crucial for high-risk patients.
