Key finding
Use of the smartphone application was associated with a greater improvement in medication adherence over six months (adjusted beta coefficient (a β ) = 0.062; 95% confidence interval (CI) = 0.010–0.123).
This study evaluated the impact of a smartphone-based intervention on medication adherence in adults with Type 2 diabetes and hypertension in Ghana, finding mixed results.

Study focus
This study evaluated the impact of a smartphone-based intervention on medication adherence in adults with Type 2 diabetes and hypertension in Ghana, finding mixed results.
Improving medication adherence is crucial for managing chronic conditions like diabetes and hypertension. This study's findings suggest that while smartphone interventions may offer some benefits, they may not be sufficient alone to ensure significant improvements in adherence. Understanding these dynamics can help healthcare providers tailor interventions more effectively.
The study design was a non-randomized controlled trial, which may introduce bias. The sample size and generalizability of findings may be limited. Statistical significance was not achieved, raising questions about clinical relevance.
