Epidemiological study using the HCUP Nationwide Inpatient Sample (1998-2008) to quantify national trends in spinal fusion volume, patient demographics, and hospital charges. Findings are benchmarked against laminectomy, hip replacement, knee arthroplasty, percutaneous transluminal coronary angioplasty, and coronary artery bypass graft. The study asks whether fusion growth outpaced other major inpatient procedures and how patient and hospital characteristics changed over the decade.
The rapid expansion of spinal fusion from 1998 to 2008 was not simply driven by an aging population. The disproportionate 239% growth in patients 65 and older, against only 11% demographic growth in that cohort, and the shift toward lumbar degenerative disc disease as the primary indication both reflect a genuine lowering of surgical thresholds.
As a trainee, knowing these numbers matters when you are evaluating a patient with lumbar DDD or when you are asked to justify operative management. Lumbar degenerative disc disease became the leading fusion diagnosis by 2008, and the elderly are now a major operative population. These trends directly shape preoperative counseling about expected perioperative outcomes.
The mortality data provide reassurance: even as the operative population aged and volume surged, in-hospital mortality fell to 0.25% and length of stay shortened. Improved perioperative care offset case complexity.
The 7.9-fold rise in the national bill to $33.9 billion is the number that drives policy conversations about fusion utilization. When attendings and policymakers debate whether fusion is overused, this paper is the quantitative foundation of that debate.
