Insights
Primary care physicians in Brazil often deviate from heart failure management guidelines. Limited access to diagnostic tools like echocardiograms and recommended medications hinders optimal patient care.
Area of Science:
- Cardiology
- Public Health
- Evidence-Based Medicine
Background:
- Heart failure (HF) presents a significant public health challenge in Brazil due to its high prevalence.
- Primary care management of HF is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the adherence of primary care physicians in Niterói, Rio de Janeiro, to Brazilian Society of Cardiology (BSC) guidelines for heart failure management.
- To identify specific areas of divergence in clinical practice.
Main Methods:
- A cross-sectional study involving 167 adult patients diagnosed with heart failure.
- Data collection included questionnaires, physical exams, ECG, chest X-ray, and echocardiography (echo) as the gold standard.
- Analysis compared physician practices against established BSC guidelines.
Main Results:
- Echocardiography confirmed HF in only 66.5% of cases; 40.6% lacked prior diagnostic imaging.
- Significant underuse of echo (11.4%), angiotensin-converting enzyme inhibitors (ACEIs) (64.1%), and beta-blockers (BBs) (26.0%) was observed.
- Commonly prescribed BBs lacked proven mortality benefits; guideline-recommended drug combinations were underutilized.
Conclusions:
- A notable gap exists between current primary care practices and BSC heart failure guidelines.
- Limited availability of diagnostic tools (echo) and recommended medications, coupled with insufficient information, restricts optimal management.
- Implementing continuous medical training programs is essential to improve guideline adherence and evidence-based practice in primary care.
Introduction:
Heart failure (HF) is an important public health concern in Brazil due to its high prevalence. Our objective was to study the performance of primary care physicians of the public health system in the management of heart failure in the city of Niterói, Rio de Janeiro state, comparing their practice to that recommended by the Brazilian Society of Cardiology (BSC) guidelines.
Methods:
In a cross-sectional study, 167 patients aged over 18, with a primary diagnosis of heart failure (HF), were studied at the university hospital by questionnaire, physical exam, electrocardiogram (ECG), chest X-ray, and echocardiogram (echo) as the gold standard exam.
Results:
HF was not confirmed by echo criteria in 56 cases (33.5%). Sixty-nine patients (40.6%) had not previously undergone any diagnostic exam. Mean age was 61 years (+/- 13.3) and 57% were women. The main divergences from the guidelines were underuse of echo (11.4%), angiotensin-converting enzyme inhibitors (ACEIs) (64.1%) and beta-blockers (BBs) (26.0%), and the most often prescribed of the latter were those without benefits in morbidity and mortality --propranolol (15.6%) and atenolol (6.6%). The association of ACEIs and BBs was used in 25% of patients. Diuretics were the most prescribed (64.7%) and spironolactone was used in 9.0% of cases.
Conclusion:
There is a significant divergence between primary practice and the BSC guidelines. In this setting, the limited availability of echo and of the recommended drugs, combined with a lack of information, restricts their use. A program to improve adherence to the guidelines and to an evidence-based approach, through continuous medical training, should be implemented to improve the quality of primary care.
