Using PROMIS-29 to predict Neck Disability Index (NDI) scores using a national sample of cervical spine surgery patients.

Patient reported outcome measures (PROMs) are valuable tools for evaluating the success of spine surgery, with the Neck Disability Index (NDI) commonly used to assess pain-related disability. Recently, patient-reported outcomes measurement information system (PROMIS) has gained attention in its ability to measure PROs across general patient populations. However, PROMIS is not condition-specific so spine researchers are reluctant to incorporate it in place of common legacy measures.
