Overview

The goal of this cluster randomized trial is to learn if eDrugSafe, a mobile web platform for drug electronic labeling (e-labeling) and medication management, can improve medication adherence and self-efficacy in adults who take multiple medications. This study will also assess whether eDrugSafe is feasible and acceptable for use in real clinical settings, especially in local pharmacies.

The main questions it aims to answer are:

• Can eDrugSafe improve medication adherence, self-efficacy, and quality of life for adults taking multiple medications and reduce hospitalizations?
• Is eDrugSafe acceptable and feasible for implementing drug e-labeling and supporting medication management in community settings?

Researchers will compare eDrugSafe to usual care (traditional paper methods) to see if eDrugSafe is effective in supporting adults who take multiple medications, and if it can be feasibly implemented in local pharmacies.

Participants will:

• Visit a local pharmacy randomly assigned to use eDrugSafe or traditional care methods and decide if they wish to join the study.
• Use either eDrugSafe to access medication information and manage their medication history, or receive usual care with paper-based methods, for 6 months.
• Complete surveys at the start of the study, at 3 months, and at 6 months to measure effectiveness and implementation outcomes.
