Abstract
Objective: To develop and evaluate a patient-centric medication module within a personal health record (PHR) app for capturing medication use, focusing on accuracy, usability, and concordance. Materials and Methods: The medication module offered 4 entry methods: picklist, National Drug Code (NDC), free-text, and portal import, with the first 2 leveraging RxNorm and openFDA APIs. Patients from an integrated delivery network (IDN) created medication lists and recorded daily use in the app's diary. Pharmacists evaluated medication accuracy by reviewing patient-uploaded medication images. Usability was measured using the System Usability Scale (SUS). Concordance was assessed by comparing Electronic Health Records (EHR) with diary entries. Results: Over a 14-day period, 85 patients entered 617 medications, with 533 logged in the diary representing current use. Picklist was the most used entry method. Overall medication entry accuracy was 92% (picklist 97%; NDC 87%; free-text 84%; and portal import 100%). The mean system usability score was 56.5 for the study app (patients) and 80.8 for the medication module (pharmacists). EHR concordance with diary entries was low (25% using the 14-day window; 53% using a 1-year window); most unmatched entries were over-the-counter (OTC) medications. Discussion: Accurate and complete medication records are essential for the safe and effective use of medications. This patient-centric medication module supported accurate capture of prescription and OTC medications. Gaps in EHR data highlight the need to improve medication record accuracy and reconciliation. Conclusion: Patient-generated health data can have a central role in creating the "Best Possible Medication History" envisioned by the World Health Organization.

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
