surgery cost-effectiveness research
´ RESULTS Thirty-seven cost-effectiveness studies on spine surgery were
included in the present study.
´ Twenty-seven (73%) of the studies involved the lumbar spine
´ Ten (27%) involved the cervical spine.
´ Of the 37 studies, 13 (35%) used Medicare, 12 (32%) used a case-costing
database, 3 (8%) used cost-to-charge ratios (CCRs), 2 (5%) used a combination
of Medicare reimbursements and CCRs, 3 (8%) used the United Kingdom
National Health Service reimbursement system, 2 (5%) used a Dutch
reimbursement system, 1 (3%) used the United Kingdom Department of Health
data, and 1 (3%) used the Tricare Military Reimbursement system.
´ Nineteen (51%) studies completed their cost analysis from the societal
perspective, 11 (30%) from the hospital perspective, and 7 (19%) from the payer
perspective. Of those studies with a societal perspective, 14 (38%) reported
