Factors associated with non-adherence to medication in hypertensive patients: baseline assessment of the ESSENCE study

Resumo

Objective: to evaluate factors associated with therapeutic adherence among hypertensive
patients treated at a community pharmacy. Methods: A descriptive secondary analysis of
the baseline data from the ESSENCE study, which included hypertensive patients aged
30 to 69 years, followed up at a community pharmacy. Sociodemographic and clinical
variables were evaluated as possible predictors of medication adherence. Adherence was
measured using the Brief medication Questionnarie (BMQ), and the variables of interest
were collected through interviews. Results: A total of 160 patients were evaluated, with
76.6% being female and an average age of 53 years (± 9.08). A 59.4% adherence rate
to antihypertensive treatment was found. Among the variables evaluated as predictors,
only the total number of medications used (p≤0.001) and the number of daily doses in
the therapeutic regimen (p-value = 0.029) showed a statistically significant association.
Conclusion: The findings highlight the need to develop strategies aimed at simplifying
therapeutic regimens to promote medication adherence.
