Establishing Normal Patient-Reported Outcomes Measurement Information System Physical Function and Pain Interference Scores

摘要

Numerous recent studies have demonstrated the validity and efficiency of the National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) forms in patients undergoing orthopaedic surgical procedures. It is assumed that a score of 50 in each domain represents the health state of a “reference” population, but this threshold has not been definitively proven. In order to truly assess whether a given orthopaedic intervention is successful, the comparative scores of healthy individuals must be known for any given health domain measured. Therefore, the purpose of this study was to determine baseline scores for the PROMIS general physical function (PROMIS-PF), pain interference (PROMIS-PI), and upper-extremity physical function (PROMIS-UE) domains in physically healthy, asymptomatic adult individuals. We hypothesized that, in individuals <40 years old, the mean PROMIS-PF and PROMIS-UE scores would be >50 and PROMIS-PI scores would be <50. We further hypothesized that these scores would be impacted by participant age.
