Abstract
<h3>Background</h3> Evidence regarding the degree and direction of economic impacts of implementing Advance Care Planning (ACP) is inconsistent. Also, available reviews have not systematically assessed the quality of the costing data in the primary studies. We aimed to synthesize current evidence on the economic impacts of implementing ACP and explore implications for policy and practice. <h3>Methods</h3> We conducted a comprehensive search of online bibliographic databases. Reference lists of included articles were also reviewed. We assessed the quality of costing in studies using the Consensus on Health Economics Criteria Checklist (CHEC). <h3>Results</h3> We included 33 studies; the majority were from the USA (78.8%). Studies were conducted in various settings, mostly hospitals (60%). Almost 64% of studies reported cost savings from the healthcare systems’ perspectives; no study included patients’ perspectives (out-of-pocket-costs). Assessing quality of costing using CHEC revealed weaknesses in studies including: flaws with costs identification (37.9%), measurement (39.3%), and valuation (44.8%); no consideration of intervention costs (87.9%); not including all relevant variables in sensitivity analyses (34.5%); and not discounting the costs (55.6%). <h3>Discussion</h3> We detected substantial methodological issues with current economic evaluations of ACP that compromise the validity of evidence. To inform policy makers about ACP, which is a multifaceted process, methodologically robust studies are needed that capture costs of the program from all major payers. A comprehensive report on cost evaluations is highly recommended. Meanwhile, respecting patient choice remains a valid clinical basis for promoting use of ACP.

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
