Age-associated degenerative disease of the spine is highly prevalent in the United States, and is the most common indication for spinal surgery in patients 65 years of age and older. Estimates of the direct costs associated with spine surgery have been reported as high as $100 billion. Given its rising utility and high associated costs, laminectomy represents an ideal candidate for value-based analysis. Value in the context of health care can be defined as the proportion of the beneficial outcomes provided by a health care service to the cost of rendering that service. Market and regulatory forces have pushed current surgical practice towards a more value-based bundled payment model focused on value alignment.Analyses of several surgical procedures have revealed that higher surgeon and hospital volumes are correlated with improved patient outcomes–whether via additional surgeon experience, streamlined surgical protocols, or comprehensive multi-disciplinary care teams. Additionally, higher volume surgeons and hospitals are able to render these improved outcomes at a lower cost, a well described phenomenon in business management referred to as “economies of scale.” The relationship between procedural volume and value of care delivered has been increasingly investigated in the setting of spinal decompression surgery. To our knowledge, only one previous study by Schoenfeld, et al. has used data-driven methodology to establish volume benchmarks for surgeons and hospitals performing spinal decompression surgery, although this study was limited by producing only a single threshold. At present, there remains a need for determining additional evidence-based volume thresholds in the setting of laminectomy in order to stratify surgeons and hospitals into multiple volume categories and ultimately provide a clinically translatable volume-value relationship for laminectomy.
