Purpose: Arterial hypertension is one of the most common diseases in the world, presenting a great impact on global mortality. Despite having good medication, the best control depends on patients adherence. Our aim is to characterize the relationship of adherence to medication in hypertensive patients with consultation length and other organizational factors of healthcare systems.Patients and methods: We performed a comprehensive review of literature using the MeSH terms hypertension and medication adherence. 61 articles were selected for inclusion and adherence parameters were extracted, allowing us to estimate the mean adherence for each country. The adherence was then correlated with organizational aspects of healthcare systems: consultation length, number of health providers (doctors, nurses and pharmacists), number of hospital beds, health expenditure and general government expenditure.Results: Adherence to medication ranged between 11.8% in Indonesia and 85.0% in Australia. There is much heterogeneity in methodology, but the Morisky Medication Adherence Scale was the preferred method, used in 63.6% of the cases. We found no relation with consultation length, but a significant one with the greater number of health professionals available. Some differences were observed when considering European countries or Morisky Medication Adherence Scale alone.Conclusion: The better the drugs, the better the control of blood pressure, if patients take them. Rather than investing in the prescription of more drugs, it is important to address non-adherence and reduce it to promote better blood pressure control. Organizational factors are relevant constraints and depend on administrative and political decisions. Although they are not always considered, they greatly impact the adherence to medication.
