Prediction of post-interventional physical function in diabetic foot ulcer patients using patient reported outcome measurement information system (PROMIS)

•Patient Reported Outcomes Measurement Information System (PROMIS) data reveal diabetic foot ulcer patients’ physical function averaging two standard deviations below the U.S. average.•Our findings indicate that surgical interventions do not necessarily improve physical function in diabetic foot ulcer population.•We introduce a predictive model to estimate post-operative physical function.•This proposed equation can aid in patients understanding of expected post-operative physical function and modifiable factors to optimize functional outcome.
