Introduction and Objective: Diabetic foot ulcer disease (DFUD) carries a very high mortality. Identifying predictors of long-term survival is crucial for risk stratification and individualising treatment. Cardiovascular and renal risk factors are recognised in DFUD, but the impact of frailty is unclear. We evaluated demographic, clinical and frailty-related predictors of delayed healing and all-cause mortality in people with DFU. Methods: We retrospectively analysed 283 consecutive patients attending a tertiary DFU service between 01/01/2015 and 31/12/2016. Demographics, comorbidities (Charlson Comorbidity Index), ulcer severity (SINBAD score) and frailty (Clinical Frailty Scale CFS, 1 = very fit to 9 = terminally ill) were recorded. Associations with time to healing were examined using linear regression, and predictors of 10-year mortality using multivariable logistic regression adjusted first for demographic and non-modifiable factors, then for modifiable clinical factors. Results: At 10-year follow-up, 69.3% of patients (n = 196) had died. Non-survivors were older (73.7 vs 60.7 years; p 0.001), frailer (CFS 5.2 vs 3.8; p 0.001) and had greater comorbidity (Charlson Index 7.6 vs 4.8; p 0.001) than survivors. Higher frailty (β = 0.20; p = 0.035) and ulcer severity (β = 0.24; p = 0.002) independently delayed healing. In multivariable models, frailty (OR 1.66, 95% CI 1.09-2.53), QRISK3 score (OR 1.05, 95% CI 1.01-1.09), comorbidity (OR 1.29, 95% CI 1.02-1.63) and HbA1c (OR 1.02, 95% CI 1.01-1.04) independently predicted mortality. Conclusion: Frailty and ulcer severity(SINBAD Score)independently predicted delayed healing of DFU, while frailty, cardiovascular risk and comorbidity burden independently predicted long-term mortality. Routine assessment of frailty in people with DFUD, and tailoring interventions to preserve or enhance physical function, may improve healing and ultimately improve survival. Disclosure N.
