Resumo: This is an evaluative study, with sequential explanatory mixed methods, aimed at evaluating the performance of the Brazilian Mobile Emergency Medical Service (SAMU) in the Grande ABC region, located in the state of São Paulo, Brazil. In the quantitative approach, an analysis of interrupted time series was performed to evaluate the immediate and gradual effects of the SAMU on hospital mortality due to acute myocardial infarction. The qualitative approach was conducted via semi-structured interviews and a thematic analysis was applied for the interpretation of the results, exploring the attitudes and values of the interviewees regarding the performance of SAMU in the Grande ABC region. Interrupted time series analysis showed a -0.04% reduction in the underlying mortality rate since SAMU implementation (95%CI: -0.0816; -0.0162; p-value = 0.0040) and a reduction in the mortality level, -2.89 (95%CI: -4.3293; -1.4623; p-value = 0.0001), both with statistical significance. To improve the robustness of the results, a control region was used, showing a statistically significant difference in the post-intervention result of -0.0639 (95%CI: -0.1060; -0.0219; p-value = 0.0001). The interviews revealed that the SAMU has the potential to intervene in the prognosis of transported cases, however, challenges related to the availability of beds, expansion of telemedicine, and continuous training of professionals for qualified emergency care in the event of a heart attack must be overcome. The results indicate that the studied intervention is part of a set of factors that, together, generate more conditions to achieve a better result.

En el enfoque cuantitativo, se realizó un análisis de series temporales interrumpidas para comprobar los efectos inmediatos y graduales de la intervención sobre la mortalidad intrahospitalaria por infarto agudo de miocardio. El enfoque cualitativo se llevó a cabo a través de entrevistas semiestructuradas y para la interpretación de los resultados se aplicó un análisis temático, investigando las actitudes y valores de los entrevistados sobre el desempeño del SAMU en la región Grande ABC. Los análisis de series de tiempo interrumpido mostraron una reducción -0,04% en la tasa de mortalidad subyacente desde la implementación del SAMU (IC95%: -0,0816; -0,0162; p = 0,0040) y una reducción en el nivel de mortalidad, -2,89 (IC95%: -4,3293; -1,4623; p = 0,0001), ambos con significación estadística. Con el fin de mejorar la solidez de los resultados, se utilizó un control de región, que mostró una diferencia estadísticamente significativa en la tendencia del resultado post intervención de -0,0639 (IC95%: -0,1060; -0,0219; p = 0,0001). Las entrevistas revelaron que el SAMU tiene el potencial de intervenir en la prognosis de los casos trasportados, sin embargo, deben superarse los desafíos relacionados con la disponibilidad de camas, expansión de la telemedicina y el entrenamiento continuo de profesionales para la asistencia cualificada en emergencias, en caso de un ataque al corazón. Los resultados indican que la intervención estudiada es parte de un conjunto de condiciones que, juntas, generan más condiciones para alcanzar un mejor resultado.Estudo avaliativo com uso de métodos mistos na tipologia explanatória sequencial cujo objetivo foi avaliar o desempenho do Serviço de Atendimento Móvel de Urgência (SAMU) na região do Grande ABC, Estado de São Paulo, Brasil. Na abordagem quantitativa, foi realizada análise de séries temporais interrompidas para testar os efeitos imediatos e graduais da intervenção sobre a mortalidade hospitalar por infarto agudo do miocárdio. A abordagem qualitativa foi realizada através de entrevistas semi-estruturadas, e a análise temática foi aplicada para a interpretação dos resultados, explorando as atitudes e valores dos entrevistados em relação ao desempenho do SAMU no Grande ABC. A análise de série temporal interrompida mostrou uma redução de -0,04% na taxa de mortalidade subjacente desde a implementação do SAMU (IC95%: -0,0816; -0,0162; p = 0,0040) e uma redução no nível de mortalidade, de -2,89 (IC95%: -4,3293; -1,4623; p = 0,0001), ambas estatisticamente significativas. Para melhorar a robustez dos resultados, foi utilizada uma região de controle, o que mostrou uma diferença estatisticamente significativa na tendência pós-intervenção de -0,0639 (IC95%: -0,1060; -0,0219; p = 0,0001). De acordo com as entrevistas, o SAMU tem o potencial de intervir no prognóstico dos pacientes transportados; entretanto, em casos de infarto agudo do miocárdio, diversos desafios precisam ser superados, relacionados à disponibilidade de leitos, expansão da telemedicina e capacitação permanente das equipes de atendimento qualificado em emergências. Os resultados indicam que a intervenção faz parte de um conjunto de fatores que, conjuntamente, geram mais condições para alcançar melhores resultados.Reports in Public HealthCadernos de Saúde Pública2022-06-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontext/htmlapplication/pdfhttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/8094Reports in Public Health; Vol. 38 No. 5 (2022): MayCadernos de Saúde Pública; v. 38 n. 5 (2022): Maio1678-44640102-311Xreponame:Cadernos de Saúde Públicainstname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZenghttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/8094/18142https://cadernos.ensp.fiocruz.br/ojs/index.php/csp/article/view/8094/18143Catia Cristina Martins de OliveiraJosé Luis Guedes dos SantosHillegonda Maria Dutilh Novaesinfo:eu-repo/semantics/openAccess2024-03-06T15:30:21Zoai:ojs.teste-cadernos.ensp.fiocruz.br:article/8094Revistahttps://cadernos.ensp.fiocruz.br/ojs/index.php/csphttps://cadernos.ensp.fiocruz.br/ojs/index.php/csp/oaicadernos@ensp.fiocruz.br||cadernos@ensp.fiocruz.br1678-44640102-311Xopendoar:2024-03-06T13:09:17.124103Cadernos de Saúde Pública - Fundação Oswaldo Cruz (FIOCRUZ)true
