Preventing amputations from diabetes mellitus: the Indian Health Service experience

Area of Science:

• Public Health
• Diabetes Management
• Podiatry

Background:

• Diabetes mellitus poses a significant health burden on American Indians and Alaskan Natives.
• Lower-extremity amputation (LEA) is a common and serious complication of diabetes in these populations, occurring at 2-3 times the rate of other diabetic groups.
• The Indian Health Service (IHS) has prioritized LEA prevention over the past 12 years.

Purpose of the Study:

• To evaluate the effectiveness of LEA prevention strategies implemented by the IHS.
• To identify key interventions and system changes that reduce LEA rates in high-risk populations.
• To guide the dissemination of successful comprehensive diabetic footcare approaches.

Main Methods:

• Development and validation of screening criteria for primary care settings (1988-1992).
• Implementation of targeted prevention efforts: self-care foot education, protective footwear, and routine podiatry care.
• Augmentation of interventions with system changes: team coordination, patient tracking, practice guidelines, and outreach programs.

Main Results:

• Interventions focusing on high-risk individuals led to 25-50% reductions in LEA rates in Alaska and northern Minnesota.
• System-based approaches, combined with targeted interventions, achieved a 50-75% reduction in LEA incidence.
• These findings highlight the impact of comprehensive care models on preventing diabetes-related amputations.

Conclusions:

• Targeted prevention strategies and comprehensive system changes are effective in reducing lower-extremity amputations in American Indians and Alaskan Natives with diabetes.
• Ongoing efforts focus on disseminating these successful system-based approaches and expanding access to diabetic footcare resources in tribal communities.
• Sustained public health focus and resource allocation are crucial for continued progress in LEA prevention.
