The Eurodiale Study
ObjectiveLow health-related quality of life (HRQoL) has been consistently reported to be associated with poor prognosis for a variety of health outcomes in various settings. We aimed to evaluate whether HRQoL in patients presenting with new diabetic foot ulcers has prognostic significance for ulcer healing, major amputation and death.Research design and methodsWe followed 1088 patients with new diabetic foot ulcers presenting for treatment at one of the 14 centers in 10 European countries participating in the Eurodiale study, prospectively until healing (76.9%), major amputation (4.6%) or death (6.4%) up to a maximum of 1 year. At baseline, patient and ulcer characteristics were recorded as well as EQ-5D: a standardised instrument consisting of five domains and a VAS scale for use as a measure of HRQoL. The prognostic influence of the EQ-5D domains was evaluated in multivariable Cox regression analyses on the time-to-event data, adjusting for baseline clinical characteristics of the ulcer and co-morbidities.ResultsWhile predictive effects of HRQoL, adjusted for possible confounders, were absent for time to healing, decreased HRQoL especially in the physical domains were statistically significant for major amputation (Mobility, Self-Care, Usual Activities) and death (Self-care, Usual Activities, Pain/Discomfort).ConclusionsLow HRQoL appears to be predictive for major amputation and death, but high HRQoL does not increase healing. Future studies into the influence of HRQoL on ulcer outcome are important in attempts to decrease treatment failure and mortality.
