In total, 28,561 revascularizations were performed, 16,675 open and 12,673 endovascular. There were 5036 readmissions (17.6%) and 1251 30 day amputations (4.5%).
American Indian patients had the highest readmission rate (22.0% of 109), followed by Black (19.6% of 5705), and White (18.2% of 17566). Pacific Islander patients had the highest rate of insulin dependent diabetes (60.7% of 28), followed by American Indian (47.7% of 109), and Asian (42.4% of 362). Pacific Islanders had the highest rate of dialysis dependence (32.1% of 28), followed by American Indian (25.7% of 109), Asian (18.5% of 362).
After multivariate adjustment, readmission was most associated with dialysis dependence (OR 1.63 [1.46-1.81], p < 0.0001), followed by insulin dependent diabetes (1.29 [1.19-1.40], p < 0.0001), and hypertension (1.12 [1.01-1.23], p < 0.01).
30 day amputation was most associated with dialysis dependence (1.84 [1.56-2.18], p < 0.0001) and Black patient race (1.42 [1.23-1.65], p < 0.0001).
Conclusion:
Dialysis dependence was the largest negative predictor of readmission and 30 day amputation after CLTI revascularization. Black patients had the highest odds of 30 day amputation.
