Objective
While visual analogue score (VAS) metrics are among the most universally adopted patient-reported outcome measures (PROMs), there is limited research on the influence of back and leg pain on the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) scores. Here we assess the association of VAS back and VAS leg scores with PROMIS PF in the setting of minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). Secondarily, we determine if PROMIS PF is more influenced by back or leg pain.
Methods
A prospective surgical registry was reviewed from May 2015 to November 2018. Inclusion criteria were primary, single-level MIS TLIFs. We excluded multilevel procedures and patients without preoperative PROMs. Pre- and postoperative PROMIS PF, VAS back, and VAS leg scores were recorded at 6 weeks, 12 weeks, 6 months, and 1 year. A Pearson correlation evaluated PROMIS PF association with VAS back and VAS leg scores. A Fisher z-test compared correlations. Linear regression evaluated PROMIS with VAS back and VAS leg scores.
Results
Our cohort was comprised of 146 subjects. 40.4% were female and the average age of 51 years. VAS back demonstrated a stronger correlation than VAS leg with PROMIS PF at all timepoints. PROMIS PF scores were negatively associated with both VAS back and VAS leg at all timepoints. Fisher z-test revealed VAS back to have a stronger correlation with PROMIS PF (p = 0.025) than VAS leg.
Conclusion
In the setting of MIS TLIF, physical function as evaluated by PROMIS PF, had a stronger correlation with VAS back than VAS leg at 6 months. This suggests that postoperative PROMIS PF scores may be more influenced by back pain than with leg pain.

Objective
This study examines the associations between preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) score, measured by PROMIS-PF and the change between pre- and postoperative PROMIS-PF scores.
Methods
A prospectively maintained surgical registry was retrospectively reviewed for spine surgeries between May 2015–June 2019. Inclusion criteria were primary, single-level minimally invasive transforaminal lumbar interbody fusions. Revisions, multilevel procedures, and patients missing preoperative surveys were excluded. Patients were grouped by preoperative PROMIS-PF scores of ≥ 35 and < 35, with higher scores indicating greater PF. A chi-squared and Student t-test were used to analyze categorical and continuous variables respectively. Linear regression evaluated the relationship of PROMIS-PF score improvement.
Results
Of the 180 subjects, 84 were in the PROMIS-PF < 35 group which had more obese patients (p < 0.001) and more males (p = 0.001). Length of stay was greater for the PROMIS-PF < 35 group (36.2 hours vs. 28.7 hours, p = 0.014). PROMIS-PF and Oswestry Disability Index scores were significantly different between subgroups at all timepoints. PROMIS-PF < 35 cohort had larger postoperative PROMIS-PF improvements at 6 weeks (p = 0.008) and 12 weeks (p = 0.003). Linear regression demonstrated a negative association between preoperative PROMIS-PF scores and improvement at 6 weeks, 12 weeks, 6 months, and 2 years (p < 0.001). PROMIS-PF < 35 demonstrated significantly lower rate of achieving minimum clinically important difference at 6 months, otherwise no difference observed throughout the 2-year follow-up.
Conclusion
Up to 6 months postoperatively, lower preoperative PROMIS-PF scores were associated with larger PROMIS-PF improvements. Understanding the relationship preoperative PROMIS-PF scores have with postoperative improvement may enable better patient counseling.

Objective
Assess preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) scores and differences between preoperative and postoperative PROMIS-PF scores for patients undergoing anterior cervical discectomy and fusion (ACDF).
Methods
After Institutional Review Board approval, a prospectively maintained surgical registry was retrospectively reviewed for elective spine surgeries of nontraumatic, degenerative pathology between 2015–2018. Inclusion criteria were primary or revision, single-level ACDF procedures. Multilevel procedures and patients without preoperative surveys were excluded. A preoperative PROMIS score cutoff of 35 divided patients into PROMIS-PF score categories (e.g. , ≥ 35.0, < 35.0). Categorical and continuous variables were evaluated with chi-square tests and t-tests. Linear regression analyzed PROMIS-PF score improvement.
Results
Eighty-six patients were selected, the high and low PROMIS-PF subgroups only differed in mean age (49.1 vs. 41.3, p = 0.002). Significant differences in PROMIS-PF scores were observed among high and low preoperative PROMIS-PF score subgroups at 6 weeks (p = 0.006), 12 weeks (p = 0.006), and 6 months (p = 0.014). Mean differences between preoperative and postoperative PROMIS-PF scores were significantly different between the high and low PROMIS-PF subgroups at 6 weeks (p = 0.041) and 1 year (p = 0.038). A significant negative association was observed between preoperative PROMIS scores and magnitude of improvement at the 6-week postoperative time point (slope = -0.6291, p < 0.001).
Conclusion
Patients with low preoperative PROMIS-PF scores demonstrated greater improvements at 6 weeks and 1 year. Clinicians should consider patients with low preoperative PROMIS-PF scores to be in the unique position to potentially experience larger postoperative improvement magnitudes than patients with higher preoperative PROMIS-PF scores.

Objective
To assess the relationship of preoperative physical function, as measured by Patient-Reported Outcome Measurement Information System Physical Function (PROMIS PF), to improvement in mental health, as evaluated by Short Form-12 Mental Component Summary (SF-12 MCS) following anterior cervical discectomy and fusion (ACDF).
Methods
Patients undergoing primary ACDF were retrospectively reviewed and stratified based on preoperative PROMIS PF scores. PROMIS PF cohorts were tested for an association with demographic characteristics and perioperative variables using chi-square analysis and multivariate linear regression. Multivariate linear regression was utilized to determine the association between PROMIS PF cohorts and improvement in SF-12 MCS.
Results
A total of 129 one- to 3-level ACDF patients were included: 73 had PROMIS PF < 40 (“low PROMIS”) and 56 had PROMIS PF ≥ 40 (“high PROMIS”). The low PROMIS cohort reported worse mental health preoperatively and at all postoperative timepoints except for 1 year. Both cohorts had similar changes in mental health from baseline through the 6-month follow-up. However, at 1 year. postoperatively, the low PROMIS cohort had a statistically greater change in mental health score.
Conclusion
Patients with worse preoperative physical function reported significantly worse preoperative and postoperative mental health. However, patients with worse preoperative physical function made significantly greater improvements in mental health from baseline. This suggests that patients with worse preoperative physical function can still expect significant improvements in mental health following surgery.
