PROMIS scores correlate strongly with traditional legacy measures which can help reduce survey fatigue and possibly improve quality.



The Patient Reported Outcomes Measurement Information System (PROMIS) was developed to provide measures of patient-reported symptoms and healthcare outcomes across a variety of conditions in an easily accessible manner. The purpose of this study was to validate PROMIS against traditional legacy measures in patients undergoing hip arthroscopy for femoral acetabular impingement (FAI).


Outcome measures collected pre- and post-operatively included PROMIS pain interference (PI) and physical function (PF), mHHS, HOS (Activities of Daily Living (ADL) and Sport subscales), NAHS, and Visual Analog Pain Scale (VAS). Pearson’s correlation coefficients were calculated between each outcome measure.


Strong correlations were observed between the PROMIS PF T-Score and the mHHS (r=0.64-0.83, p<0.0001), HOS- ADL (r=0.54-0.81, p<0.0001), HOS-Sport (r=0.55-0.74, p<0.0001) and NAHS (r=0.61-0.78, p<0.0001) measurement tools. PROMIS CAT PI T-Score and VAS also demonstrated a strong correlation (r=0.64-0.80, p<0.0001).


PROMIS PF scores correlate strongly with mHHS, HOS-ADL, HOS-Sport and NAHS scores at all time points. Likewise, PROMIS PI scores correlate strongly with VAS pain scores. On average patients completing PROMIS need to fill out only 4 or 5 questions. This study supports the use of PROMIS as an efficient, valid outcome tool for patients with FAI undergoing hip arthroscopy.
