Abstract
In this longitudinal study of 1666 persons with diabetes, there was an observed trend toward an increased risk for amputation (chi(2) test for trend, 108.0; P<.001), higher-level amputation (chi(2) test for trend, 113.3; P<.001), and lower extremity-related hospitalization (chi(2) test for trend, 118.6; P<.001) with increasing infection severity. The Infectious Diseases Society of America's foot infection classification system may be a useful tool for grading foot infections.
