Background 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). Methodology Outcome measures collected pre- and post-operatively included PROMIS Pain Interference (PI) and Physical Function (PF), modified Harris Hip Score (mHHS), Hip Outcome Score-Activities of Daily Living and Sport (HOS-ADL and HOS-Sport), Nonarthritic Hip Score (NAHS), and Visual Analog Scale (VAS). Pearson's correlation coefficients were calculated between each outcome measure. Results 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 Computer Adaptive Testing PI T-Score and VAS also demonstrated a strong correlation (r = 0.64-0.80, p < 0.0001). Conclusions 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 four or five questions. This study supports the use of PROMIS as an efficient, valid outcome tool for patients with FAI undergoing hip arthroscopy.
