Summary

Increased use of foot care clinics is linked to less severe lower extremity amputations for patients with peripheral vascular disease. More clinic visits correlated with distal amputations, suggesting limb preservation potential.

Area of Science:

  • Vascular Surgery
  • Podiatry
  • Health Services Research

Background:

  • Peripheral vascular disease (PVD) is a leading cause of lower extremity amputation.
  • Diabetes is a common comorbidity that increases amputation risk.
  • The role of specialized foot care in amputation level is not well-defined.

Purpose of the Study:

  • To investigate the association between foot care clinic utilization and the level of lower extremity amputation in patients with PVD.
  • To determine if diabetes diagnosis influences amputation level in this patient cohort.

Main Methods:

  • Retrospective analysis of 3945 patients undergoing lower extremity amputation for PVD.
  • Data extracted from Department of Veterans Affairs (VA) medical records (fiscal year 1991).

  • Patients categorized into above-knee, below-knee, and foot/ankle amputation groups based on procedural codes.

    • Main Results:

    • Higher frequency of foot care clinic visits was significantly associated with more distal amputations (foot/ankle vs. above-knee).
    • Patients with above-knee amputations had an average of 1.0 foot care visit, compared to 2.8 for below-knee and 5.3 for foot/ankle amputations.
    • Patients with diabetes as a codiagnosis were more likely to undergo distal amputations.

    Conclusions:

    • Increased utilization of designated foot care clinics may be associated with limb preservation, leading to more distal amputations.
    • Foot care clinics could play a vital role in managing PVD and diabetes to prevent severe amputations.
    • Further research into the impact of preventative foot care is warranted.
