A Novel Digital Pill System for Medication Adherence Measurement and Reporting: A Usability Validation Study
ABSTRACT
Background:
Medication nonadherence is a costly problem that is common in clinical use and and clinical trials alike with significant adverse consequences. Digital pill systems have proven to be effective and safe solutions to the challenges of nonadherence, with documented success in improving adherence and health outcomes.
Objective:
This human factors validation study evaluated a novel digital pill system, the ID-CapTM System from etectRx, for usability among patient users in a simulated real-world use environment.
Methods:
Seventeen patients of diverse background who regularly take oral prescription medications were recruited. After training and a period of training decay, participants were asked to complete 12 patient use scenarios during which errors or difficulties were logged. Participants also were interviewed about their experience with the ID-Cap System.
Results:
In this human factors validation study, patient users completed 97% of the use scenarios successfully, and 75% of these were completed without any failures or errors. Participants found the ID-Cap System easy to use and were able to accurately and proficiently record ingestion events using the device.
Conclusions:
Participants demonstrated the ability to safely and effectively use the ID-Cap System for its intended use. Regardless of age, educational level, or background, patients were able to use it successfully. The ID-Cap System has great potential as a useful tool for encouraging medication adherence and can be easily implemented by patient users. Clinical Trial: Not applicable
