Risk factors for infection in patients with chronic leg ulcers: A survival analysis.

This study has validated the predictive ability of factors which have been found in a cross-sectional study to be significantly associated with infection in patients with leg ulcers, including venous leg ulcers, arterial leg ulcers and mixed aetiology leg ulcers. Results showed that patients with chronic leg ulcers, who either presented with depression, used walking aids, had a calf ankle ratio <1.3, a wound area ≥10 cm2 or an ulcer with slough tissue, had greater likelihood of developing infection compared to those without these factors.
