Patient-Reported Outcomes for Fractures of the Acetabulum: A Comparison Between Patient-Reported Outcomes Information System and Traditional Instruments.

This study supports that the PROMIS Mobility and Physical Function surveys are much more efficient instruments for evaluating patients with acetabulum fractures when compared with the SMFA and SF-36. Convergent validity of the PROMIS instruments was overall strong but weaker and more moderate in those with a long-term follow-up, and additional study is suggested for longer-term outcomes. Level of education did not influence survey completion time; however, it took markedly longer time for older individuals and African Americans to complete the SMFA and SF-36.
