Abstract
OBJECTIVES: Healthcare policy makers and payers require cost-effectiveness evidence to inform their treatment funding decisions. Thus, in 2008, the United Kingdom's National Institute of Health and Clinical Excellence analyzed the cost effectiveness of spinal cord stimulation (SCS) compared with conventional medical management (CMM) and with reoperation and recommended approval of SCS in selected patients with failed back surgery syndrome (FBSS). We present previously unavailable details of the National Institute of Health and Clinical Excellence analysis and an analysis of the impact on SCS cost effectiveness of rechargeable implanted pulse generators (IPGs). METHODS: We used a decision analytic model to examine the cost effectiveness of SCS versus CMM and versus reoperation in patients with FBSS. We also modeled the impact of nonrechargeable versus rechargeable IPGs. RESULTS: The incremental cost-effectiveness of SCS compared with CMM was pound5624 per quality-adjusted life year, with 89% probability that SCS is cost effective at a willingness to pay threshold of pound20,000. Compared with reoperation, the incremental cost-effectiveness of SCS was pound6392 per quality-adjusted life year, with 82% probability of cost-effectiveness at the pound20,000 threshold. When the longevity of an IPG is 4 years or less, a rechargeable (and initially more expensive) IPG is more cost-effective than a nonrechargeable IPG. DISCUSSION: In selected patients with FBSS, SCS is cost effective both as an adjunct to CMM and as an alternative to reoperation. Despite their initial increased expense, rechargeable IPGs should be considered when IPG longevity is likely to be short.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
