Summary
For spinal pain patients, higher pain interference significantly correlates with lower physical function. The Patient Reported Outcome Measurement Information System (PROMIS) Pain Interference (PI) scale effectively predicts physical function (PF) in this population.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Health Outcomes
Background:
- Spinal pain significantly impacts patients' quality of life and functional abilities.
- Accurate assessment of pain interference and physical function is crucial for effective treatment planning.
Purpose of the Study:
- To investigate the relationship between the Patient Reported Outcome Measurement Information System (PROMIS) Pain Interference (PI) and PROMIS Physical Function (PF) scales.
- To determine if PROMIS PI can predict PROMIS PF in patients with spinal pain.
Main Methods:
- Retrospective analysis of prospectively collected patient-reported outcome data from a university spine clinic.
- Pearson correlation and linear regression were used to analyze the relationship and predictive power between PROMIS PI and PF scores.
- Statistical significance was set at P < 0.05.
Main Results:
- A total of 1,992 participants were included in the analysis.
- A strong negative correlation (r = -0.717, P < 0.05) was found between PROMIS PF and PROMIS PI scores.
- PROMIS PI scores significantly predicted PROMIS PF scores (β = -0.707, P < 0.001).
Conclusions:
- There is a significant negative correlation between self-reported physical function and pain interference in patients with spinal pain.
- The PROMIS PI scale serves as a valuable adjunct measure for assessing physical function in individuals experiencing spinal pain.
