Key result
Among patients with hypertension in primary care, 71.1% were non-adherent to pharmacological treatment, with limited economic access significantly increasing the risk of non-adherence (OR 5.715).
Why the study?
Low adherence to pharmacological treatment in hypertension is linked to poor blood pressure control and increased cardiovascular complications and death, prompting an investigation into factors conditioning adherence.
What factors condition adherence to pharmacological prescription in patients with hypertension attending primary healthcare units?

Low adherence to antihypertensive medication is highly prevalent (71.1%) and is significantly driven by socioeconomic factors, depression, and health system barriers such as drug supply and patient satisfaction.
May highlight adherence barriers in primary-care hypertension; hypothesis-generating and requires prospective validation.
Low adherence to pharmacological treatment in patients diagnosed with hypertension is related to poor blood pressure control and an increased incidence of cardiovascular complications and deaths. A cross-sectional study was performed to determine conditioning factors towards adherence. Questionnaires and clinical evaluations were applied to 187 patients attending three first-level health units; in 130 of them laboratory tests were carried out. Diagnostic criteria were based on the European Clinical Practice Guidelines; adherence was based on the Morinsky test. 57.1% of patients had blood pressure values above the controlled threshold, and 71.1% reported non-adherence to pharmacological prescription. Factors associated whit low adherence were coexisting moderate to severe depression (OR = 2,054; CI 1,064 - 3,964), low educational level (3.75 ± 3.05 years), poor understanding of medical prescriptions (OR = 2.3 CI 1.188 - 4.477), irregular supply and limited economic access to prescribed drugs ((OR = 1.97 CI 1.08 - 3.817), and low satisfaction with the care offered at health services (OR = 2.45; CI 1.202-5.00).

Solórzano et al. (2021) conducted a cross-sectional in Hypertension (n=187). Limited economic access to prescribed drugs vs. Adequate economic access was evaluated on Non-adherence to pharmacological prescription (OR 5.715, 95% CI 2.857-11.43, p=<0.001). Among patients with hypertension in primary care, 71.1% were non-adherent to pharmacological treatment, with limited economic access significantly increasing the risk of non-adherence (OR 5.715).
