Patient Preference and Adherence

Summary
Smart pill packaging improves medication adherence, especially with a mobile app. This technology offers a feasible solution for better long-term disease management and patient support.
Area of Science:
- Digital Health
- Medication Adherence Technology
- Health Informatics
Background:
- Medication non-adherence is a significant obstacle to effective chronic disease management.
- Smart packaging offers innovative digital solutions for monitoring and improving patient adherence.
- Previous research indicates a need for user-friendly adherence monitoring tools.
Purpose of the Study:
- To evaluate the usability and feasibility of a smart blister pack (Cerepak®) for medication adherence monitoring.
- To compare adherence monitoring with and without a companion mobile application (MEMS® Mobile).
- To assess user experience and identify barriers and facilitators for smart packaging adoption.
Main Methods:
- A randomized controlled trial involving 36 healthy adults over eight weeks.
- Participants used the smart blister pack with (intervention) or without (control) a mobile app, simulating twice-daily medication intake.
- Usability was measured using the System Usability Scale (SUS) and user experience surveys, supplemented by semi-structured interviews and electronic/pill count adherence data.
Main Results:
- The intervention group using the smart blister pack with the mobile app reported significantly higher usability scores (median SUS: 80.0) compared to the control group (67.5; p = 0.0007).
- Participants found the app's features beneficial for structure, motivation, and ease of use, despite some technical challenges.
- Electronic adherence rates were 91.7% (app group) vs. 86.2% (non-app group), and pill count adherence was 96.4% vs. 88.0%, respectively, with no statistically significant difference observed between groups.
Conclusions:
- The smart blister pack, especially when combined with a mobile app, demonstrates high usability and feasibility for daily medication management and adherence tracking.
- Findings support the potential of this smart packaging technology for improving medication adherence in clinical settings.
- Further research in patient populations and long-term implementation studies is warranted to validate these promising results.
