Abstract
To determine therapeutic adherence in patients with arterial hypertension based on a single blood pressure reading. A descriptive, observational, cross-sectional, and prospective study was conducted in patients with systemic arterial hypertension with a disease duration of at least two months. The Morisky-Green scale was used to assess therapeutic adherence, and the chi-square test was used for statistical analysis, with a p-value <0.05 considered significant. Fifty-eight patients were included, with a mean age of 58.43 ± 10.63 years. Of these, n=30 (51.7%) were women and n=28 (48.3%) were men, with a mean disease duration of 28.21 ± 10.40 years. Thirty (30) of the patients (51.7%) had disease control goals prior to hospitalization; however, treatment adherence was 69%, with a p-value <0.00001, indicating a statistically significant association between therapeutic adherence and the reasons for inadequate adherence. Therapeutic adherence in patients with arterial hypertension in a second level of care is higher than the national average.
