Patient-caregiver twinned mobile phone application to promote medication adherence

Background Poor medication adherence (MA) is prevalent globally. MA assessment, often based on scales or pill count, lacks actionability. A mobile application (app), MediEasy, targeting patients on multiple daily medications, has been developed to engage their caregivers to enhance their MA. Objectives This pilot single-arm study aimed to determine the feasibility, acceptability, utility and glycaemic control of the MediEasy-app by patients with type-2 diabetes mellitus and their caregivers. Methods 20 Multi-ethnic Asian patients aged 51 to 70 years with suboptimal glycaemic control (HbA1c>7.5%) and their caregivers were recruited at a Primary care outpatient clinic in Singapore. The Medieasy app that contains the following major functionalities such as the alerts to take medications, embedded medication details, personalized dosing options (such as frequency and scheduling dosage settings) is twinned to their designated caregivers. The Caregivers can remind the patients who missed the scheduled medication intake when the paired device was alerted. Results 85% (17/20) of the participants used the app for the entire 4 weeks, reflecting feasibility; 3 dropped out due to technical glitches or failure to adhere to protocol. The app was activated with an average of 2.8 times per day showing adequate utility. The 17 participants and their caregivers agreed that the app supported medication adherence. Their mean HbA1c decreased by 0.2% after 12 weeks of app usage. Conclusions The results showed feasibility, utility and acceptability of the MediEasy-app, with improved glycaemic control after its usage
