Implementación de la Iniciativa HEARTS en Argentina: primeros resultados

Abstract

Cardiovascular diseases are the leading cause of mortality and morbidity in the Region of the Americas, and hypertension is one of the main risk factors. In 2018, Argentina began implementing the HEARTS Initiative in five primary health care centers, through the National Plan for the Prevention and Control of Arterial Hypertension. This study presents the impact its implementation has had on the indicators of effective coverage, treatment, combination therapy, and control. The HEARTS Initiative has multiple components; these include training health teams, reassigning tasks based on the transfer of clinical competencies, providing automatic and clinically validated blood pressure measurement devices, and using a single standardized treatment protocol. A longitudinal data model (generalized estimating equation analysis) was used, and the information from the five health centers was grouped using weighted averages according to the size of the population under coverage. Analysis of the results was stratified into two time periods delimited by the imposition of restrictions due to COVID-19. During the first period of 18 months, significant improvement was observed in treatment (5.9%; p<0.01) and combination therapy (13.4%; p<0.01), with no significant change in coverage (8.4%; p=0.87) and with a paradoxical decrease in control (−3.3%; p=0.02). When the period of restrictions was compared to the previous period, a generalized reduction was observed in all indicators, particularly coverage (−23.6%; p<0.01) and control (−12.5%; p<0.01). However, treatment and combination therapy levels remained above baseline values (1.7%; p<0.01 and 5.4%; p<0.01, respectively).

As doenças cardiovasculares são a principal causa de morbimortalidade, e a hipertensão, seu principal fator de risco. Em 2018, a Argentina começou a implementar a Iniciativa HEARTS em 5 centros de atenção primária à saúde por meio do Plano Nacional de Prevenção e Controle da Hipertensão Arterial. Este estudo apresenta o impacto de sua implementação nos indicadores de cobertura efetiva, tratamento, tratamento combinado e controle. A Iniciativa HEARTS inclui vários componentes. Entre eles, se destacam a capacitação das equipes de saúde, a reorganização das tarefas com base na transferência de competências clínicas, a disponibilização de aparelhos automáticos e clinicamente validados para aferição da pressão arterial e a utilização de um único protocolo padronizado de tratamento. Foi utilizado um modelo de equações de estimativas generalizadas para a análise de dados longitudinais, e as informações dos 5 centros de saúde foram agrupadas por meio de médias ponderadas de acordo com o tamanho da população coberta. A análise dos resultados foi estratificada em dois períodos de tempo delimitados pela irrupção das restrições em virtude da COVID-19. Durante os primeiros 18 meses, houve melhora significativa no tratamento (5,9%; p<0,01) e no tratamento combinado (13,4%; p<0,01), sem mudança significativa na cobertura (8,4%; p=0,87) e com uma diminuição paradoxal no controle (−3,3%; p=0,02). Durante as restrições e em relação ao período anterior, verificou-se redução generalizada em todos os indicadores, principalmente na cobertura (−23,6%; p<0,01) e no controle (−12,5%; p<0,01). No entanto, os níveis de tratamento e tratamento combinado persistiram acima dos valores basais (1,7%; p<0,01 e 5,4%; p<0,01, respectivamente).
