Predicting the risk of amputation and death in patients with diabetic foot ulcer. A long-term prospective cohort study of patients in Tanzania.

Neuropathy and PAD were the only two characteristics that increased both the risk of amputation and death. Amputation showed to contribute to an increased risk of death and those participants who eventually died had a higher risk of amputation. Delay in attending appointments after ulceration is shown to increase the risk of amputation. In addition, the participants with PAD showed a significantly shorter time to both amputation and death while neuropathy was only associated with decreased time to death. Amputation history and death during follow-up decrease the time to death and amputation respectively.
