Our study aims to evaluate the correlation of Patient-Reported Outcomes Measurement Information System physical function (PROMIS PF) with legacy patient-reported outcome measures (PROMs) among patients undergoing anterior cervical discectomy and fusion (ACDF). A prospectively maintained database was retrospectively reviewed for ACDF surgeries performed between May 2015 and September 2017. Inclusion criteria were primary elective, single- or multilevel ACDFs for degenerative spinal pathology.

Mean scores were calculated for visual analogue scale (VAS) neck, VAS arm, Neck Disability Index (NDI), 12-Item Short Form Physical Component Score (SF-12 PCS), and PROMIS PF at preoperative and 6-week, 12-week, 6-month, 1-year, and 2-year postoperative timepoints. A t-test and Pearson correlation coefficient were utilized to evaluate score improvement and PROM relationships respectively. The 50 subject cohort was 60.0% male, 50% obese (body mass index ≥ 30 kg/m2) and had an average age of 50.9 years. Significant improvements were demonstrated for VAS neck and NDI at all postoperative timepoints (p < 0.001) and for SF-12 and PROMIS PF at all timepoints except 6 weeks (p ≤ 0.025). VAS arm improvement was seen up to 1 year (p ≤ 0.016). PROMIS PF demonstrated strong correlations with NDI and SF-12 PCS at all evaluated timepoints and with VAS neck at all postoperative timepoints except 6 weeks (all p < 0.01). PROMIS PF was strongly correlated with pain, disability, and physical function up to 2 years for patients undergoing ACDF. Our results support the long-term validity of PROMIS PF for measurement of patient-reported physical function among ACDF cohorts.
