[Do West African cardiologists adhere to the guidelines for the management of heart failure ?] / Les cardiologues ouest-africains suivent-ils les « guidelines ¼ sur la prise en charge de l'insuffisance cardiaque ?

INTRODUCTION: Adherence to guidelines for the management of heart failure (HF) has been shown to be a strong predictor of reduced hospitalisations. The aim of this study was therefore to investigate the adherence of West African cardiologists to guidelines for the management of HF. METHODOLOGY: This was a prospective cross-sectional multicentric study (Côte d'Ivoire, Togo, Benin and Burkina-Faso). The "ADDress your Heart" survey developed was administered online to assess cardiologists' adherence to the guidelines for the management of heart failure. RESULTS: 62.3% of the 106 participants reported that they followed the guidelines closely. The therapeutic classes indicated as first-line by the latest guidelines were insufficiently suggested by physicians: 57.5% for mineralocorticoid receptor antagonists, 41.5% for gliflozins and 30.1% for sacubitril-valsartan In univariate logistic regression, affiliation with a teaching hospital OR [95% CI] = 3.0 [1.3-6.8], p < 0.01 ; access to scientific cardiology journals OR [95 % CI] = 3.4 [1.3-8.9], p = 0.01; and frequent attendance at conferences OR [95% CI]=1.8 [1.2-2.9], p < 0.01, were associated with guideline compliance. These factors persisted in multivariate analysis. CONCLUSION: Adherence of West African cardiologists to guidelines on the management of heart failure was moderate. If affiliation to a university hospital is difficult to apply to all cardiologists, access to scientific cardiology journals and frequent attendance in conference should be encouraged.

Poor adherence to medication and salt restriction as a barrier to reaching blood pressure control in patients with hypertension: Cross-sectional study from 12 sub-Saharan countries.

BACKGROUND: Sub-Saharan Africa is experiencing a rising burden of hypertension. Antihypertensive medications and diet are the cornerstone of effective hypertension control. AIMS: To assess adherence to medication and salt restriction in 12 sub-Saharan countries, and to study the relationship between adherence and blood pressure control in patients with hypertension. METHODS: We conducted a cross-sectional survey in urban clinics in twelve sub-Saharan countries. Data were collected on demographics, treatment and adequacy of blood pressure control in patients with hypertension attending the clinics. Adherence was assessed by questionnaires completed by the patients. Hypertension grades were defined according to European Society of Cardiology guidelines. Association between adherence and blood pressure control was investigated using multilevel logistic regression analysis, adjusting for age, sex and country. RESULTS: Among the 2198 patients, 77.4% had uncontrolled blood pressure, 34.0% were poorly adherent to salt restriction, 64.4% were poorly adherent to medication and 24.6% were poorly adherent to both. Poor adherence to salt restriction (odds ratio [OR] 1.33, 95% confidence interval [CI] 1.03-1.72), medication (OR 1.56, 95% CI 1.25-1.93) or both (OR 1.91 1.39-2.66) was related to uncontrolled blood pressure. Moreover, poor adherence to both medication and salt restriction was related to a 1.52-fold (95% CI 1.04-2.22), 1.8-fold (95% CI 1.22-2.65) and 3.08-fold (95% CI 2.02-4.69) increased likelihood of hypertension grade 1, 2 and 3, respectively. CONCLUSIONS: High levels of poor adherence to salt restriction and medication were noted in this urban sub-Saharan study; both were significantly associated with uncontrolled blood pressure, representing major opportunities for intervention to improve hypertension control in sub-Saharan Africa.
