Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The commonly used scales (ODI+JOA-29+VAS) lack the assessment of lumbar stiffness, and there is no scale for evaluating lumbar stiffness in China.Based on the Delphi method and the analytic hierarchy process, this study will improve and optimize the quality of life evaluation system for patients with severe degenerative lumbar disease, so as to obtain a concise, practical, and effective patient-reported outcome instrument.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Although lumbar fusion can improve function by correcting deformity,restoring spinal stability,and reducing pain, it also by intention leads to spinal stiffness which can impair function of daily activities.The commonly used scales (ODI+JOA-29+VAS) lack the assessment of lumbar stiffness.Lumbar Stiffness Disability Index (LSDI) has not been used widely, and there is no scale for evaluating lumbar stiffness in China.In addition, even if LSDI is modified, there is still an evaluation dilemma: after lumbar long-segment fixation, the pain and neurological function-related scale scores show that the quality of life is improved, while the lumbar stiffness-related scale scores show that the quality of life is reduced . So overall, is the patient's quality of life improved or decreased? Simply combining these two types of scales cannot explain clearly.

This study can be roughly divided into the following 5 main steps:

Step 1:Collect and sort out the dimensions and exhaustive items that affect the patients' quality of life by systematically reviewing the related literature and a qualitative interview study.

Step 2: Through a cross-sectional survey and experts' meetings, the items is initially optimized, and 35-45 items will be retained.

Step 3: Screen 20-25 excellent items by 2-3 rounds of Delphi method, then use the analytic hierarchy process to determine the weight of each item, so as to establish a initial PRO instrument.

Step 4: Verify the reliability and validity of the initial PRO instrument, and further optimize the initial PRO instrument in order to be used in clinical practice and research.

Step 5: Verify the responsiveness of the initial PRO instrument, calculate the ES, SRM, AUC and MICD values of the initial PRO instrument.

Finally, a novel, concise, practical, and effective PRO instrument for use in degenerative lumbar disease patients will be established.
