简要总结
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.
详细描述
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.

结局指标
主要结局
The Oswestry Disability Index (ODI)
时间窗: 12 months after lumbar fusion
Use the Oswestry Disability Index (ODI) to assess the quality of life of Patients with lumbar degenerative diseases before lumbar fusion.The minimum value of ODI score is 0 and the maximum value is 50. Higher ODI scores mean a worse outcome.
The Japanese Orthopedic Association score(JOA-29)
时间窗: 12 months after lumbar fusion
Use the Japanese Orthopedic Association score(JOA-29) to assess the quality of life of Patients with lumbar degenerative diseases before lumbar fusion.The minimum value of JOA-29 score is 0 and the maximum value is 29. Higher JOA-29 scores mean a better outcome.
The novel PRO instrument
时间窗: 12 months after lumbar fusion
Use the novel PRO instrument to assess the quality of life of Patients with lumbar degenerative diseases before lumbar fusion.The minimum value of the novel PRO instrument score is 0 and the maximum value is 100. Higher the novel PRO instrument scores mean a worse outcome.
