Development and evaluation of a patient-centric approach for accurate medication capture.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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.
