Compliance with the Prescription of Antihypertensive Medications and Blood Pressure Control in Primary Care.

BACKGROUND:: Hypertension is the most prevalent risk factor for cardiovascular disease, and its proper control can prevent the high morbidity and mortality associated with this disease.

OBJECTIVE:: To assess the degree of compliance of antihypertensive prescriptions with the VI Brazilian Guidelines on Hypertension and the blood pressure control rate in primary care.

METHODS:: Cross-sectional study conducted between August 2011 and November 2012, including 332 adults ≥ 45 years registered in the Family Doctor Program in Niteroi and selected randomly. The analysis included the prescribed antihypertensive classes, doses, and frequencies, as well as the blood pressure (BP) of the individuals.

RESULTS:: The rate of prescription compliance was 80%. Diuretics were the most prescribed medications, and dual therapy was the most used treatment. The most common non-compliances were underdosing and underfrequencies. The BP goal in all cases was < 140/90 mmHg, except for diabetic patients, in whom the goal was set at < 130/80 mmHg. Control rates according to these goals were 44.9% and 38.6%, respectively. There was no correlation between prescription compliance and BP control.

CONCLUSIONS:: The degree of compliance was considered satisfactory. The achievement of the targets was consistent with national and international studies, suggesting that the family health model is effective in BP management, although it still needs improvement.

FUNDAMENTO:: A hipertensão arterial é o fator de risco mais prevalente para a doença cardiovascular e seu controle adequado pode prevenir a elevada morbi-mortalidade associada a esta doença.

OBJETIVO:: Avaliar o grau de conformidade das prescrições de anti-hipertensivos com as VI Diretrizes Brasileiras de Hipertensão e a taxa de controle pressórico na atenção básica.

MÉTODOS:: Estudo transversal conduzido entre agosto de 2011 e novembro de 2012, incluindo 332 adultos ≥ 45 anos cadastrados no Programa Médico de Família de Niterói e selecionados aleatoriamente. Foram analisadas as classes de anti-hipertensivos prescritos, suas doses e frequências, bem como a pressão arterial (PA) dos indivíduos.

RESULTADOS:: A taxa de conformidade das prescrições foi de 80%. Diuréticos foram as medicações mais prescritas e a terapia dupla foi o tratamento mais utilizado. As não conformidades mais comuns foram subdoses e subfrequências. A meta de PA para todos os casos foi < 140/90 mmHg, exceto para diabéticos, que foi < 130/80 mmHg. As taxas de controle de acordo com essas metas foram de 44,9% e 38,6%, respectivamente. Não houve correlação entre conformidade da prescrição e controle pressórico.

CONCLUSÕES:: O grau de conformidade foi considerado satisfatório. O alcance das metas foi compatível com estudos nacionais e internacionais, sugerindo que o modelo de saúde da família é efetivo no manejo da PA, embora ainda necessite aprimoramento.
