Abstract

Objectives: To assess the level of medication adherence and associated factors in older outpatients with HFrEF.


Methods: From July 2024 to May 2025, this cross-sectional study screened and recruited outpatients aged ≥60 years undergoing treatment for HFrEF at Thong Nhat Hospital and University Medical Center Ho Chi Minh City. Medication adherence was evaluated using the 8-item Morisky Medication Adherence Scale (MMAS-8). Logistic regression was employed to identify factors associated with low to medium levels of adherence.


Results: Among 293 analyzed patients (male: 60.1%, mean age: 72.9±9.3), the rates of high, medium, and low medication adherence were 25.9% (n = 76), 62.5% (n = 183), and 11.6% (n = 34), respectively. Forgetting to take medication was the most commonly reported issue (42.3%) based on MMAS-8 items. Multivariate logistic regression identified depression as a factor significantly associated with an increased likelihood of low to medium adherence (Odds Ratio 1.84; 95% Confidence Interval 1.06–3.22; P = 0.031).


Conclusions: In older patients with HFrEF, only about one-fourth demonstrated high medication adherence, with forgetfulness being the most prevalent cause. Depression, a common geriatric issue, was associated with poorer adherence in this patient population.
