Amputation Risk in Veterans with DFUs: What’s Driving Differences in Care and Outcomes
Summary: Recent research highlights two major drivers of amputation risk in Veterans with diabetic foot ulcers (DFUs). First, developing a DFU is the strongest independent predictor of lower-extremity amputation — increasing risk nearly 10-fold. Second, a large JAMA Network Open study of over 86,000 Veterans found significant facility-level variation across VA centers: the odds of major leg amputation within one year were 1.85 times higher between two randomly selected facilities for an otherwise average patient. While mortality rates were relatively consistent, amputation rates varied widely (facility odds ratios ranging from 0.29 to 3.53), suggesting differences in care delivery, rather than patient factors alone, play a critical role.
Key Highlights:
- DFU development increases amputation risk nearly 10-fold in Veterans
- Significant VA facility-level variation in amputation rates (MOR 1.85) despite similar patient populations
- Variation in care processes (early intervention, offloading, vascular assessment, multidisciplinary coordination) likely drives outcome differences
- Emphasizes need for standardized, high-quality DFU protocols across all facilities
