Is Pragmatically Delivered Prehabilitation Cost-effective Compared to Usual Care? A Cost-effectiveness Analysis
Bibliographic record
Abstract
A significant and growing proportion of major surgeries are undertaken in high-risk patients, where the rate of surgical complications and associated burdens are disproportionately high. Surgical prehabilitation describes the process of increasing physical and psychological reserve prior to surgery to improve postoperative outcomes and reduce the risk of harm. The impetus toward implementing prehabilitation among hospitals has followed burgeoning empirical evidence regarding its safety, feasibility, and efficacy. This thesis investigated the economic merit of prehabilitation to inform the emergent hospital implementation decision-making context. A cost-effectiveness analysis from a hospital perspective was piloted using data from a clinical trial of a pragmatic model of prehabilitation, including three iterations of prehabilitation delivery, for high-risk surgical patients in Ontario, Canada. This work contributed novel, understudied, preliminary insight regarding the economic merit of prehabilitation implementation from a hospital perspective and informed the design of future prehabilitation economics research.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
