Abstract
Medicare's annual wellness visit was introduced in 2011 to promote evidence-based preventive care and identify risk factors and undiagnosed conditions in aging adults. Use of the visit has risen steadily since then, yet its benefits remain unclear. Using national Medicare data for 2008-15, we examined claims from fee-for-service Medicare beneficiaries attributed to practices that did or did not adopt the visit. We performed difference-in-differences analysis to compare differential changes in appropriate and low-value cancer screening, functional and neuropsychiatric care, emergency department visits, hospitalizations, and total spending. Examining 17.8 million beneficiary-years, we found modest differential improvements in rates of evidence-based screening and declines in emergency department visits. However, when we accounted for trends that predated the introduction of the visit, none of these benefits persisted. In sum, we found no substantive association between annual wellness visits and improvements in care.

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
