PROMIS Physical Function and Pain Correlation with ODI and VAS in the Surgical Lumbar Disc Herniation Patient Population

BACKGROUND CONTEXT: Legacy patient-reported outcome measures such as ODI (Oswestry Disability Index) and VAS (Visual Analog Score) have become essential for analyzing treatment interventions in orthopedic spine surgery for lumbar disc herniations. Despite their usefulness, significant associated administrative burdens impose limits on completion of such measures. The Patient Reported Outcomes Measurement Information System (PROMIS) group developed a patient outcome measure based on Item Response Theory in order to improve reporting of patient symptoms, function and health and to reduce administrative burden and improve outcome measure reliability.
