Research
Aafiyet isn't built on a hunch. Decades of published research show that medication non-adherence is one of healthcare's largest solvable problems — and that sustained, personal follow-up is what actually moves it. These are the studies that shape what we build.
How big the problem is.

Medication adherence among heart failure (HF) patients in the Middle East remains a critical, under-explored issue. This systematic review examines medication adherence rates and their influencing factors in this region.
Osterberg L, Blaschke T · New England Journal of Medicine · 2005
The landmark NEJM review: average adherence in chronic disease sits near 50%, non-adherence drives a large share of preventable hospitalisations, and clinicians consistently overestimate how well their patients take their medication.
What non-adherence does to patients and health systems.
Chowdhury R, et al. · European Heart Journal · 2013
Good adherence was associated with roughly 45% lower mortality on statins and 29% lower on blood-pressure medicines; the authors estimate poor adherence accounts for about 9% of cardiovascular events in Europe.
Usmani OS, et al. · Respiratory Research · 2018
Critical inhaler-handling errors were significantly associated with worse disease control (more exacerbations) and higher healthcare costs — adherence to correct technique materially affects outcomes.
The interventions with real evidence behind them.
Ruppar TM, Delgado JM, Temple J · European Journal of Cardiovascular Nursing · 2015
Adherence interventions worked but the average effect was modest; programmes focused only on adherence and aimed at patients (not providers) tended to do better.
Nieuwlaat R, et al. · Cochrane Database of Systematic Reviews · 2014
The landmark honest finding: even the best current adherence interventions are complex and only modestly effective. The most promising were tailored, ongoing support from pharmacists and allied health staff — which is exactly the relationship-based model this platform automates.
The case for scaling follow-up with technology.
Belete AM, et al. · BMC Endocrine Disorders · 2023
Adding text-message reminders to usual care produced a small-to-moderate improvement in adherence, with larger gains when the programme ran longer than six months.
Wieland ML, et al. · JAMA Network Open · 2024
A short, culturally tailored digital intervention produced a modest but significant improvement in glycemic control, and was highly acceptable and scalable in primary care.
