  • Overview

    This Test-Case is a retrospective study leveraging claims data to compare reoperation and reimaging rates in patients treated with lumbar discectomy. Chronic back pain as a result of bulging or herniated discs is a common condition. Although discectomy is generally considered a successful treatment for patients with bulging or herniated discs who are non-responsive to conservative therapies, large population-based studies show a high failure rate over time.

    This project is identifying a comparison cohort of patients treated with lumbar discectomy in administrative claims data to quantify the burden of additional imaging and treatment post lumbar discectomy and determine the burden of reherniation or failed discectomy in a commercially insured population. As one of the first US-population-based studies to investigate post-discectomy outcomes, the goal of this Test-Case is to assess the potential impact of the utilization of a device that reduces the risk of reherniation in patients with massive spinal disc defects.

    The specific aim of this project is to characterize the outcomes of post-operative imaging, post-operative readmission, and reoperation following an index discectomy surgery. The project will establish the potential to initiate surveillance within the U.S. through the NESTcc Data Network and will specifically provide for the comparison to both the current standard of care in the U.S. as well as to the data from the pivotal study upon which the U.S. marketing approval was based.
