ABSTRACT
STUDY AIM: to analyze patient-related factors that may influence adherence in patients with heart failure in an African cardiology department. METHODOLOGY: This prospective observational study took place in the in-patient department of the Abidjan cardiology institute and enrolled consecutive patients hospitalized for decompensated heart failure from January to November 2014. The inclusion criteria were chronic heart failure in patients older than 18 years, developing for at least 6 months and treated by medication. The revised heart failure compliance questionnaire was used. RESULTS: The study included 121 patients. Overall adherence was poor in 88.4% of patients. Multiple linear regression analyses showed that use of traditional medicine was associated with poor adherence for the following 3 components: keeping follow-up appointments, medication intake, and sodium limitations. Overall adherence increased with the number of hospitalizations (OR = 1.69, 95% CI 1.13-2.53; p = 0.01). This increase persisted after adjustment for age, sex, educational level, marital status, medical insurance coverage and the use of alternative medicines (traditional and Chinese) (OR = 1.70; CI 1.12-2.28; p = 0.01). CONCLUSION: Adherence among black Africans with heart failure remains poor, influenced too much by traditional medicine. Therapeutic education is essential to improve patients' knowledge about their disease and its treatment.
