Introduction: Rapid reperfusion of the responsible artery is fundamental in patients with acute ST-segment elevation myocardial infarction (STEMI). Present guidelines recommend that the interval between the patient’s hospital admission and the opening of the artery by primary angioplasty (“door-to-balloon” time) be less than 90 minutes. Objective: The objective of this study was to evaluate the proportion of patients with acute STEMI that did not undergone primary angioplasty within recommended times and to use the Health Failure Mode and Effect Analysis (HFMEA) and the Stream Analysis in order to identify the failures, to determine its aetiology and repercussions in a cause-effect logic, and to propose changes that lead to the correction of the situation. Results: Between June 2005 and December 2008, 415 patients, aged 62+12 years, were submitted to direct angioplasty in the context of acute STEMI. “Door-toballoon” time was 116+97 minutes; 44% of the patients received treatment after the recommended 90 minutes. The admission screening systems were unable to identify 22% of patients with acute STEMI as emergency admissions or urgency admissions. The HFMEA team identified as the most scored causes of failures the effectiveness of the Manchester Triage System in classifying the STEMI patients, the excessive time to perform electrocardiogram and the lack of an angiography suite for cardiology department. Conclusion: A significant number of patients with acute STEMI are treated by direct angioplasty after the time recommended by the guidelines. The HFMEA and the Stream Analysis are important diagnostic tools for the identified dysfunctions and the change proposal that may lead to improvement.
Introdução: É fundamental a rápida reperfusão da artéria responsável pelo enfarte agudo do miocárdio com supradesnivelamento ST (EAMST). As actuais guidelines recomendam que o intervalo entre a chegada do doente ao hospital e o momento em que a artéria é aberta, por angioplastia primária (tempo “porta-balão”), seja inferior a 90 minutos. Objectivo: Foi objectivo deste estudo avaliar a proporção de doentes com EAMST que não recebeu a angioplastia primária dentro dos tempos recomendados e, usar a metodologia da Health Failure Mode and Effect Analysis (HFMEA) e Stream Analysis para detectar as falhas, determinar a sua etiologia e repercussões, numa lógica de causalidade, e propor as alterações que conduzam à sua correcção. Resultados: Entre Junho de 2005 e Dezembro de 2008 foram incluídos 415 doentes, com idade 62+12 anos, tratados por angioplastia directa no contexto de EAMST. O tempo “porta-balão” médio foi de 116+97minutos e 44% dos doentes receberam o tratamento para além dos 90 minutos recomendados. Os sistemas de triagem não conseguiram identificar como emergente ou urgente 22% dos doentes com EAMST. A equipa de HFMEA apontou como causas mais pontuadas a falta de fiabilidade do protocolo de Manchester, a demora na realização do electrocardiograma e a ausência de uma sala de angiografia específica para a cardiologia. Conclusão: Um importante número de doentes com EAMST foi tratado, por angioplastia directa, para além do tempo recomendado pelas guidelines. A HFMEA e a Stream Analysis são importantes instrumentos de diagnóstico das disfunções identificadas e na proposta de alterações que conduzam à sua melhoria.
