Multi-center registry data will become increasingly impotant for outcomes research.
The aim was to establish a multi-center cooperative research group to demonstrate the feasibility of developing a registry to assess the efficacy of common lumbar spinal procedures.
211 patients were screened and 204 were enrolled from 13 academic and community sites (mean 16 patients/ site) over 1 year. Mean age: 46.0 years for lumbar discectomy (N=156; 48% female) ; 58.3 years for lumbar spondylolisthesis (N=48 patients; 60% female).
A prospective 13-site registry study, conducted over 1 year, collected data from unselected patients undergoing lumbar discectomy or single-level fusion for spondylolisthesis. The goal was to enroll 200 patients. Subjects completed SF 36 and ODI scales pre-operatively, and 3, 6, and 12 months post-operatively. All patient data was entered into a secure HIPPA compliant internet-based data management platform.
There was 94% compliance with the collection of patient-reported outcomes data. Eleven complications (5.4%) reported within 1 month of surgery: 4 re-operations and 7 minor complications. At 3 months: lumbar discectomy had 26-point improvement in ODI score (46 to 20) and 33-point improvement in SF-36 physical function score (42 to 75) (P<0.001). Single level fusion for lumbar spondylolisthesis had 17-point improvement in ODI score (44 to 27) and 24-point improvement in SF-36 physical function score (47 to 61) (P<0.001). At 6 months, similar results were obtained (P<0.001).
This is study evaluated non-randomized data.
It is feasible to build a national spine registry for the collection of prospective data.
Initial results from Neuropoint SD suggest that both lumbar discectomy and single-level spinal fusion for spondylolisthesis were highly effective in actual practice. Project Roles:
