          <title>Fundamento</title>
          <p> As doen&#231;as cardiovasculares constituem um grupo importante de causas de morte no Brasil. As doen&#231;as isqu&#234;micas do cora&#231;&#227;o s&#227;o as principais causas de parada cardiorrespirat&#243;ria, levando a um impacto na mortalidade devido &#224;s doen&#231;as cardiovasculares no sistema de sa&#250;de.</p>
        </sec>
        <sec>
          <title>Objetivo</title>
          <p> Avaliar o n&#250;mero de &#243;bitos domiciliares por parada cardiorrespirat&#243;ria notificados pelo Servi&#231;o de Atendimento M&#243;vel de Urg&#234;ncia (SAMU) em mar&#231;o de 2018, 2019 e 2020.</p>
        </sec>
        <sec>
          <title>M&#233;todos</title>
          <p> Trata-se de um estudo observacional realizado a partir da an&#225;lise de dados de mortalidade por parada cardiorrespirat&#243;ria de cidad&#227;os atendidos pelo SAMU em Belo Horizonte, Minas Gerais, Brasil. Foram analisadas as caracter&#237;sticas sociais e cl&#237;nicas e as informa&#231;&#245;es de ocorr&#234;ncia. Foi avaliada a taxa de mortalidade por parada cardiorrespirat&#243;ria em rela&#231;&#227;o ao n&#250;mero total de atendimentos. Foi considerado um n&#237;vel de signific&#226;ncia de 95%.</p>
        </sec>
        <sec>
          <title>Resultados</title>
          <p> Houve um aumento nos &#243;bitos domiciliares por parada cardiorrespirat&#243;ria em mar&#231;o de 2020, em compara&#231;&#227;o com mar&#231;o de 2018 (p &lt; 0,001) e mar&#231;o de 2019 (p = 0,050). Dos &#243;bitos relatados em 2020, 63,8% dos pacientes tinham 60 anos ou mais; 63,7% das ocorr&#234;ncias foram &#224; tarde e aproximadamente 87% dos casos de parada cardiorrespirat&#243;ria notificados apresentavam comorbidades cl&#237;nicas, com hipertens&#227;o arterial sist&#234;micas e parada card&#237;aca correspondendo a 22,87% e 13,03% dos casos relatados, respectivamente. A maioria da amostra avaliada deste estudo n&#227;o teve acompanhamento m&#233;dico (88,7%).</p>
        </sec>
        <sec>
          <title>Conclus&#227;o</title>
          <p> Considerando o aumento do n&#250;mero de &#243;bitos, sugerimos reflex&#245;es e reajustes quanto ao monitoramento das doen&#231;as cr&#244;nicas n&#227;o transmiss&#237;veis durante a pandemia, bem como melhorias na vigil&#226;ncia dos &#243;bitos.

      <p>O Servi&#231;o de Atendimento M&#243;vel de Urg&#234;ncia (SAMU) representa o componente m&#243;vel de emerg&#234;ncia normativamente institu&#237;do pelo Sistema &#218;nico de Sa&#250;de (SUS). Integrante da Rede de Urg&#234;ncia e Emerg&#234;ncia desde 2003, o SAMU &#233; atualmente um servi&#231;o p&#250;blico de assist&#234;ncia que atua com o objetivo de atendimento pr&#233;-hospitalar m&#243;vel no SUS. Al&#233;m disso, este servi&#231;o transporta pacientes para hospitais privados, sendo um importante componente da admissibilidade de pacientes da rede privada de sa&#250;de.<sup><xref rid="B1" ref-type="bibr">1</xref>,<xref rid="B2" ref-type="bibr">2</xref></sup></p>
      <p>O SAMU &#233; composto por centrais de regula&#231;&#227;o e equipes de ambul&#226;ncias, compostas por m&#233;dicos e enfermeiras. De acordo com as diretrizes preconizadas pelo SUS, qualquer cidad&#227;o pode solicitar atendimento m&#243;vel pr&#233;-hospitalar por meio do acesso gratuito ao telefone, ligando para o n&#250;mero 192. Na central de regula&#231;&#227;o, um operador de telefone identifica o paciente e o local da liga&#231;&#227;o e transfere o atendimento ao m&#233;dico regulador, que pode orientar o paciente por telefone ou ligar para a equipe de assist&#234;ncia para atender &#224; solicita&#231;&#227;o do usu&#225;rio. Todas as etapas do atendimento s&#227;o registradas com o consentimento de ambas as partes, profissionais e usu&#225;rios.<sup><xref rid="B1" ref-type="bibr">1</xref></sup></p>
      <p>As equipes de ambul&#226;ncias s&#227;o compostas por unidades de suporte b&#225;sico, nas quais est&#227;o presentes um t&#233;cnico de enfermagem, motoristas e enfermeiros, e unidades de suporte avan&#231;ado, uma ambul&#226;ncia com mais recursos tecnol&#243;gicos e a presen&#231;a de m&#233;dico e enfermeiro.

      <p>As doen&#231;as cardiovasculares (DCV) constituem atualmente um importante grupo de causas de &#243;bito no Brasil e no mundo. De acordo com a Sociedade Brasileira de Cardiologia, at&#233; o primeiro dia de julho, as DCV causaram mais de 198.000 &#243;bitos entre os brasileiros em 2020.<sup><xref rid="B4" ref-type="bibr">4</xref></sup> Estas doen&#231;as incluem as doen&#231;as isqu&#234;micas do cora&#231;&#227;o, que s&#227;o as principais causas de parada cardiorrespirat&#243;ria (PCR).</p>
      <p>Segundo o Cardi&#244;metro, indicador do n&#250;mero de &#243;bitos por DCV, criado pela Sociedade Brasileira de Cardiologia, entre 2004 e 2014, as doen&#231;as isqu&#234;micas constitu&#237;ram o grupo de causas cardiovasculares com maior preval&#234;ncia de eventos de &#243;bito por DCV.<sup><xref rid="B4" ref-type="bibr">4</xref></sup> Os dados na literatura a respeito da incid&#234;ncia de PCR no Brasil s&#227;o escassos, sendo observado o impacto desse evento na mortalidade dos indiv&#237;duos.<sup><xref rid="B5" ref-type="bibr">5</xref>-<xref rid="B7" ref-type="bibr">7</xref></sup></p>
      <p>Neste contexto, este estudo tem como objetivo descrever o n&#250;mero de &#243;bitos domiciliares por PCR notificados pelo SAMU no munic&#237;pio de Belo Horizonte em 2020 e comparar os &#243;bitos domiciliares por PCR em mar&#231;o de 2020 em rela&#231;&#227;o a mar&#231;o de 2018 e mar&#231;o de 2019.</p>

      <p>Este estudo faz parte do servi&#231;o de notifica&#231;&#227;o do SAMU de Belo Horizonte, Minas Gerais, Brasil, e se refere aos dados coletados em mar&#231;o de 2018, mar&#231;o de 2019 e mar&#231;o de 2020. As notifica&#231;&#245;es foram selecionadas a partir do processamento manual de fichas referentes ao atendimento total das equipes no per&#237;odo previamente determinado. N&#227;o foram estabelecidos crit&#233;rios de exclus&#227;o para avalia&#231;&#227;o de usu&#225;rios/&#243;bitos. Assim, a amostragem foi realizada por conveni&#234;ncia, contemplando todas as notifica&#231;&#245;es cadastradas no servi&#231;o nos per&#237;odos descritos.</p>
      <p>Trata-se de um estudo observacional retrospectivo, realizado a partir da an&#225;lise de dados prim&#225;rios de mortalidade por PCR em cidad&#227;os atendidos pelo SAMU em Belo Horizonte.</p>

        <title>An&#225;lise Estat&#237;stica</title>
        <p>Foram coletadas a idade, as caracter&#237;sticas de ocorr&#234;ncia (dia do m&#234;s e hora do dia) e as caracter&#237;sticas cl&#237;nicas (causa da PCR, acompanhamento m&#233;dico e comorbidades associadas) e foi calculada a taxa de mortalidade de acordo com o sistema de notifica&#231;&#227;o do SAMU.</p>
        <p>Os dados foram coletados pelos pesquisadores do servi&#231;o e, subsequentemente, submetidos &#224; an&#225;lise descritiva. A an&#225;lise descritiva das vari&#225;veis foi realizada por meio da distribui&#231;&#227;o de frequ&#234;ncias e n&#250;meros absolutos das vari&#225;veis categ&#243;ricas. Foram estimados a preval&#234;ncia dos desfechos e os intervalos de confian&#231;a de 95% para a popula&#231;&#227;o.</p>
        <p>Para an&#225;lise dos dados, foi utilizado o programa estat&#237;stico p&#250;blico e gratuito OpenEpi&#174;. As vari&#225;veis categ&#243;ricas foram analisadas por meio da distribui&#231;&#227;o de frequ&#234;ncia e comparadas pelo teste qui-quadrado.

      <p>Foram registrados 1.662 &#243;bitos pelo SAMU nos meses de mar&#231;o de 2018 (n = 563), 2019 (n = 494) e 2020 (n = 605). Nesse per&#237;odo (mar&#231;o), o SAMU registrou 919 &#243;bitos domiciliares por PCR nos anos de 2018, 2019 e 2020, distribu&#237;dos em 260 &#243;bitos em mar&#231;o de 2018 (28,3%), 283 &#243;bitos em mar&#231;o de 2019 (30,8%) e 376 &#243;bitos em mar&#231;o de 2020 (40,9%). Observou-se que as taxas de &#243;bito para o n&#250;mero total de atendimentos no SAMU nesses per&#237;odos foram 0,51, 0,57 e 0,62, respectivamente.</p>

      <p>Como principal resultado deste estudo, observou-se aumento num&#233;rico gradativo da taxa de &#243;bitos domiciliares por PCR para o total de atendimentos pelo SAMU e aumento proporcional de 33% dos &#243;bitos domiciliares em mar&#231;o de 2020, m&#234;s em que a Organiza&#231;&#227;o Mundial da Sa&#250;de declarou a pandemia de COVID-19.<sup><xref rid="B8" ref-type="bibr">8</xref></sup></p>
      <p>Desde a confirma&#231;&#227;o do primeiro caso no Brasil, em 26 de fevereiro de 2020, a imprensa, assim como as autoridades sanit&#225;rias, na aus&#234;ncia de vacinas ou medicamentos antivirais, alertam sobre a necessidade de distanciamento social, uso de m&#225;scaras, lavagem das m&#227;os e refor&#231;o para cuidados com rela&#231;&#227;o &#224; etiqueta respirat&#243;ria. Na cidade de Belo Horizonte, a primeira notifica&#231;&#227;o de COVID-19 ocorreu em 16 de mar&#231;o de 2020; entretanto, desde a declara&#231;&#227;o mundial da pandemia, a prefeitura instituiu o isolamento social precocemente, evitando que os residentes tivessem contato n&#227;o essencial.</p>
      <p>Aproximadamente 80% dos casos de COVID-19 s&#227;o leves ou oligossintom&#225;ticos.<sup><xref rid="B9" ref-type="bibr">9</xref></sup> Um estudo recente mostra que 20% de pacientes necessitaram de cuidados hospitalares, com 5% a 15% destes sendo tratados em unidades de terapia intensiva com necessidade de suporte ventilat&#243;rio. A mortalidade para estes pacientes pode chegar a 80%.<sup><xref rid="B9" ref-type="bibr">9</xref></sup>O SARS-CoV-2 pode ser transmitido de pessoa para pessoa (contato com as m&#227;os, tosse, ou got&#237;culas de saliva) ou atrav&#233;s de superf&#237;cies e objetos contaminados pelo v&#237;rus.<sup><xref rid="B10" ref-type="bibr">10</xref></sup> Em 16 de maio de 2020, mais de 4.605.673 pessoas foram diagnosticadas com COVID-19 e houve 310.180 mortes ao redor do mundo. No Brasil, at&#233; 16 de maio de 2020, foram registrados 222.877 casos, com 15.046 &#243;bitos.<sup><xref rid="B11" ref-type="bibr">11</xref></sup> Dentre as medidas de preven&#231;&#227;o da infec&#231;&#227;o pela COVID-19, recomenda-se aos indiv&#237;duos a higieniza&#231;&#227;o das m&#227;os, superf&#237;cies e objetos com &#225;gua e sab&#227;o ou com desinfetante para as m&#227;os. Outras indica&#231;&#245;es incluem evitar o contato com os olhos, nariz e boca; o uso permanente de m&#225;scara facial; a manuten&#231;&#227;o de h&#225;bitos saud&#225;veis de alimenta&#231;&#227;o e sono; e o isolamento e distanciamento social.<sup><xref rid="B12" ref-type="bibr">12</xref></sup></p>
      <p>O aumento do n&#250;mero de mortes, no contexto da pandemia, pode agravar o medo dos usu&#225;rios de sair do isolamento social para buscar assist&#234;ncia m&#233;dica e servi&#231;os essenciais. Isso poderia atrasar a demanda por servi&#231;os de sa&#250;de que afetam a doen&#231;a subjacente. &#201; interessante notar que quase 89% da nossa amostra n&#227;o teve acompanhamento m&#233;dico; em frequ&#234;ncia semelhante (87%), a natureza da PCR foi a causa cl&#237;nica.</p>
      <p>Em um estudo recente, Gonzales-Olmo et al.,<sup><xref rid="B13" ref-type="bibr">13</xref></sup> com dados da popula&#231;&#227;o de Madrid, demonstrou elevados n&#237;veis de auto-percep&#231;&#227;o individual de maior vulnerabilidade em rela&#231;&#227;o &#224; infec&#231;&#227;o pela COVID-19 ao procurar atendimento odontol&#243;gico, considerado um servi&#231;o essencial de sa&#250;de. Assim, os pesquisadores observaram que a amostra de indiv&#237;duos com mais de 60 anos com doen&#231;as sist&#234;micas evitou o atendimento odontol&#243;gico na maioria das vezes.<sup><xref rid="B13" ref-type="bibr">13</xref></sup></p>
      <p>De acordo com os nossos resultados, Holmes et al. (2020) indicaram que houve uma quebra estrutural nas s&#233;ries temporais de interna&#231;&#245;es semanais diferidas anualmente de acordo com os servi&#231;os de emerg&#234;ncia no Reino Unido entre setembro de 2019 e abril de 2020.<sup><xref rid="B14" ref-type="bibr">14</xref></sup> Esses pesquisadores observaram o per&#237;odo de tempo correspondente a setembro de 2019 e abril de 2020.</p>
      <p>Foram desenvolvidas e est&#227;o em fase de valida&#231;&#227;o escalas para avaliar o medo dos indiv&#237;duos (como a &#8220;Escala de Medo de COVID-19&#8221;) com a finalidade de avaliar essa emo&#231;&#227;o. Espera-se que novos estudos avaliem o contexto da pandemia a esse respeito, monitorando o medo em detrimento de n&#227;o procurar servi&#231;os essenciais de sa&#250;de, melhorando a qualidade de vida e retardando a mortalidade por causas que n&#227;o envolvem COVID-19.<sup><xref rid="B15" ref-type="bibr">15</xref>-<xref rid="B17" ref-type="bibr">17</xref></sup></p>
      <p>Julia et al.,<sup><xref rid="B18" ref-type="bibr">18</xref></sup> relatam a reorganiza&#231;&#227;o do servi&#231;o de sa&#250;de na Fran&#231;a durante a pandemia. Importantes investimentos t&#234;m sido feitos em termos de teleconsultas para acompanhamento de pacientes com COVID-19, mas a popula&#231;&#227;o mais vulner&#225;vel com dificuldades de acesso &#224; internet e tecnologias digitais ou com barreiras lingu&#237;sticas permaneceu sem assist&#234;ncia adequada. Al&#233;m disso, os leitos hospitalares dispon&#237;veis foram drasticamente reduzidos e os profissionais de aten&#231;&#227;o prim&#225;ria &#224; sa&#250;de consequentemente tiveram que lidar com emerg&#234;ncias por doen&#231;as cr&#244;nicas.<sup><xref rid="B18" ref-type="bibr">18</xref></sup> As visitas domiciliares t&#234;m sido divididas por pacientes com e sem COVID-19, levando &#224; sobrecarga do servi&#231;o. J&#225; foi adotado um fluxo para a aten&#231;&#227;o b&#225;sica aos pacientes com doen&#231;as cr&#244;nicas, a fim de evitar atrasos no controle ambulatorial.<sup><xref rid="B17" ref-type="bibr">17</xref></sup></p>
      <p>Em Belo Horizonte, houve redu&#231;&#227;o da demanda da popula&#231;&#227;o por atendimento nas Unidades B&#225;sicas de Sa&#250;de e Unidades de Pronto Atendimento. Durante os primeiros quatro meses de 2019, foram atendidas 1.478.905 pessoas; no mesmo per&#237;odo de 2020, esse n&#250;mero foi de 1.215.543, o que representa uma redu&#231;&#227;o de 18%.<sup><xref rid="B19" ref-type="bibr">19</xref></sup> Dessa maneira, &#233; importante monitorar o manejo das doen&#231;as cr&#244;nicas e promover a&#231;&#245;es educativas para que a popula&#231;&#227;o compreenda a import&#226;ncia do acompanhamento da sa&#250;de e do uso regular dos medicamentos necess&#225;rios. Dessa forma, a Secretaria Municipal de Sa&#250;de de Belo Horizonte atualizou o fluxo de aten&#231;&#227;o na aten&#231;&#227;o b&#225;sica.<sup><xref rid="B19" ref-type="bibr">19</xref>,<xref rid="B20" ref-type="bibr">20</xref></sup></p>
      <p>Souza et al.,<sup><xref rid="B21" ref-type="bibr">21</xref></sup> relatam sobre a aten&#231;&#227;o prim&#225;ria &#224; sa&#250;de prestada pelo SUS no Brasil e sobre os investimentos que v&#234;m sendo destinados &#224; aquisi&#231;&#227;o de equipamentos e &#224; amplia&#231;&#227;o de leitos hospitalares para pacientes com COVID-19. Refor&#231;am a necessidade de fortalecer a aten&#231;&#227;o b&#225;sica como instrumento de preven&#231;&#227;o do colapso do sistema de sa&#250;de, evitando &#243;bitos por COVID-19 e doen&#231;as cr&#244;nicas.<sup><xref rid="B21" ref-type="bibr">21</xref></sup> &#201; necess&#225;rio refletir sobre como encontrar o equil&#237;brio para que as a&#231;&#245;es de sa&#250;de n&#227;o sejam paralisadas durante a pandemia.</p>
      <p>A Secretaria Municipal de Sa&#250;de de Belo Horizonte tem realizado a&#231;&#245;es como treinamentos por meio de confer&#234;ncias virtuais, aulas virtuais, discuss&#227;o de casos cl&#237;nicos e notas t&#233;cnicas para atendimento e fluxo de pacientes com COVID-19, estabelecendo parcerias para atendimento online e atendimento a pacientes de grupos de risco. Paralelamente, vem adotando medidas de adequa&#231;&#227;o dos servi&#231;os de urg&#234;ncia e aten&#231;&#227;o prim&#225;ria &#224; sa&#250;de, buscando n&#227;o sobrecarregar os servi&#231;os e promover melhor atendimento aos pacientes com e sem COVID-19.<sup><xref rid="B20" ref-type="bibr">20</xref></sup></p>
      <p>O aumento do n&#250;mero de &#243;bitos domiciliares tem despertado a aten&#231;&#227;o de gestores de sa&#250;de, e a ideia &#233; refor&#231;ar a import&#226;ncia do controle ambulatorial das doen&#231;as cr&#244;nicas e esclarecer as medidas de seguran&#231;a adotadas para a popula&#231;&#227;o quanto &#224;s complica&#231;&#245;es cl&#237;nicas n&#227;o relacionadas &#224; COVID-19 durante a pandemia.</p>
      <p>Este &#233; um momento favor&#225;vel para reinventar a rela&#231;&#227;o entre os usu&#225;rios e os profissionais da aten&#231;&#227;o b&#225;sica, buscando maior aproxima&#231;&#227;o para o estabelecimento de v&#237;nculos, fortalecendo a import&#226;ncia do controle das doen&#231;as cr&#244;nicas e evitando mortes desnecess&#225;rias. Tamb&#233;m &#233; necess&#225;rio implementar medidas para melhorar a vigil&#226;ncia de &#243;bitos. Os servi&#231;os de aten&#231;&#227;o prim&#225;ria &#224; sa&#250;de devem organizar a assist&#234;ncia e os fluxos de, pacientes a fim de garantir o atendimento adequado aos pacientes com e sem COVID-19.</p>
      <p>Como limita&#231;&#227;o do estudo, apontamos o alto percentual de indiv&#237;duos para os quais n&#227;o foi poss&#237;vel coletar informa&#231;&#245;es sobre a exist&#234;ncia de comorbidades (38,5% da amostra) devido &#224; falta de informa&#231;&#245;es dos familiares ou amigos entrevistados, que podem ter subestimado os valores apresentados.</p>

      <title>Conclus&#227;o</title>
      <p>Os resultados indicam um aumento no n&#250;mero de &#243;bitos domiciliares por PCR notificados pelo SAMU em mar&#231;o de 2020 em rela&#231;&#227;o a mar&#231;o de 2018 e mar&#231;o de 2019 em Belo Horizonte, Minas Gerais. Ser&#225; necess&#225;rio realizar estudos futuros com delineamento longitudinal para monitorar o aumento da mortalidade de usu&#225;rios do sistema de sa&#250;de e analisar suas rela&#231;&#245;es causais para evitar &#243;bitos por outras doen&#231;as que n&#227;o envolvam a COVID-19.</p>

          <title>Background</title>
          <p> Cardiovascular diseases constitute an important group of causes of death in the country. Ischemic heart diseases that are the main causes of cardiopulmonary arrest, leading to an impact on the mortality of the cardiovascular diseases in the health system.</p>
        </sec>
        <sec>
          <title>Objective</title>
          <p> Assess the number of home deaths by cardiopulmonary arrest notified by the Mobile Emergency Medical Service (SAMU) in March 2018, 2019 and 2020.</p>
        </sec>
        <sec>
          <title>Methods</title>
          <p> Observational study carried out from the analysis of cardiopulmonary arrest mortality data of citizens assisted by SAMU in Belo Horizonte, Minas Gerais, Brazil. Social and clinical characteristics and occurrence information of the patients were analyzed. The mortality rate due to cardiopulmonary arrest in relation to the total number of attendances was assessed. A significance level of 95% was considered.</p>
        </sec>
        <sec>
          <title>Results</title>
          <p> There was increase of home deaths due to cardiopulmonary arrest in March 2020 compared to March 2018 (p&lt;0.001) and March 2019 (p=0.050). Of the deaths reported in 2020, 63.8% of the patients were aged 60 years or older, 63.7% of the occurrences were performed in the afternoon and approximately 87% of the cardiopulmonary arrest notified had associated clinical comorbidities, with systemic arterial hypertension and heart failure represented by 22.87% and 13.03% of the reported cases, respectively. The majority of the evaluated sample of this study did not have any medical care follow-up (88.7%).</p>
        </sec>
        <sec>
          <title>Conclusion</title>
          <p> Considering the increase in the number of the deaths, we suggest reflections and readjustments regarding the monitoring of chronic non-transmissible diseases during a pandemic, as well as improvements in death surveillance. (Arq Bras Cardiol. 2021; 116(2):266-271)</p>

        <title>Introduction</title>
        <p>Mobile Emergency Care Service (SAMU) represents the mobile emergency component that is normatively instituted by the Brazilian Public Health System (SUS). A component of the Urgency and Emergency Network since 2003, SAMU is currently a public assistance service working with the objective of mobile pre-hospital assistance in SUS. In addition, this service brings patients to private hospitals, and it is an important component of admissibility of patients from the private healthcare network.<sup><xref rid="B1" ref-type="bibr">1</xref>,<xref rid="B2" ref-type="bibr">2</xref></sup></p>
        <p>SAMU comprises central regulation and ambulance teams, composed of doctors and nurses. According to the guidelines recommended by SUS, any citizen can request pre-hospital mobile assistance through free telephone access by calling the number 192. At central regulation, a telephone operator identifies the patient and the location of the call and transfers the service to the medical regulator, who can guide the patient by phone or call the assistance team to answers the user&#8217;s request. All stages of care are recorded with the consent of both parties, professionals and users.<sup><xref rid="B1" ref-type="bibr">1</xref></sup></p>
        <p>The ambulance teams consist of basic support units, in which a nursing technician, drivers and nurses are present, and advanced support units, an ambulance with more technological resources and the presence of a doctor and a nurse. Depending on regional needs, the ambulances are motorcycles, boats, or an aeromedical system consisting of a helicopter or airplane.<sup><xref rid="B3" ref-type="bibr">3</xref></sup></p>
        <p>Cardiovascular diseases (CVD) are currently an important group of causes of death in Brazil and worldwide. According to the Brazilian Society of Cardiology, as of the first day of July, CVD caused more than 198,000 deaths among Brazilians in 2020.<sup><xref rid="B4" ref-type="bibr">4</xref></sup>These diseases include ischemic heart diseases, which are the main causes of cardiopulmonary arrest (CPA).</p>
        <p>According to the <italic>Cardiom&#234;tro</italic>, an indicator of the number of deaths from CVD, created by the Brazilian Society of Cardiology, between 2004 and 2014, ischemic diseases constituted the group of cardiovascular causes with the highest prevalence of death events due to CVD.<sup><xref rid="B4" ref-type="bibr">4</xref></sup> The data in the literature regarding the incidence of CPA in Brazil are scarce, and the impact of this event on the mortality of individuals is observed.<sup><xref rid="B5" ref-type="bibr">5</xref>-<xref rid="B7" ref-type="bibr">7</xref></sup></p>
        <p>In this context, this study aims to describe the number of home deaths due to CPA notified by SAMU in the city of Belo Horizonte in 2020 and to compare the home deaths due to CRA in March 2020 in relation to March 2018 and March 2019.</p>

        <title>Methodology</title>
        <p>This study is part of the SAMU notification service in Belo Horizonte, Minas Gerais, Brazil, and it refers to data collected in March 2018, March 2019, and March 2020. The notifications were selected based on the manual handling of files regarding the total attendance of the teams in the previously determined period. Exclusion criteria were not established for evaluating users/deaths. Thus, sampling was performed for convenience, covering all notifications registered with the service during the periods described.</p>
        <p>This is a retrospective observational study carried out based on the analysis of primary data on mortality due to CPA in citizens assisted by SAMU in Belo Horizonte.</p>
        <sec>
          <title>Statistical Analysis</title>
          <p>Age, occurrence characteristics (day of the month and time of day) and clinical characteristics (cause of CPA, medical follow-up, and associated comorbidities) were collected. The mortality rate was calculated according to the SAMU notification system.</p>
          <p>The data were collected by the researchers of the service and subsequently submitted to descriptive analysis. The descriptive analysis of the variables was performed using the distribution of frequencies and absolute numbers of the categorical variables. The prevalence of outcomes and 95% confidence intervals were estimated for the population.</p>
          <p>For data analysis, the public and free OpenEpi&#174; statistical program was used. Categorical variables were analyzed using frequency distribution and compared using the chi-square test. The significance level was set at 95% (p &lt; 0.05).</p>

        <title>Results</title>
        <p>A total of 1,662 deaths were recorded by SAMU in the month of March in 2018 (n = 563), 2019 (n = 494), and 2020 (n = 605). During this period (March), SAMU reported 919 home deaths due to CPA in the years 2018, 2019, and 2020, distributed in 260 deaths in March 2018 (28.3%), 283 deaths in March 2019 (30.8%), and 376 deaths in March 2020 (40.9%). It was observed that the death rates for the total number of attendances at SAMU during these periods were 0.51, 0.57 and 0.62, respectively.</p>

        <p>As a main result of this study, a gradual numerical increase was observed in the rate of home deaths due to CPA for the total number of attendances by SAMU and a proportional increase of 33% of home deaths in March 2020, which is the month when the World Health Organization declared the COVID-19 pandemic.<sup><xref rid="B8" ref-type="bibr">8</xref></sup></p>
        <p>Since the confirmation of the first case in Brazil, on February 26, 2020, the press, as well as health authorities, in the absence of vaccines or antiviral medications, has warned of the need for social distance, the use of masks, hand washing, and reinforcement for care regarding respiratory etiquette. In the city of Belo Horizonte, the first notification of COVID-19 occurred on March 16, 2020; however, since the world declaration of the pandemic, the city government instituted social isolation early, preventing residents from non-essential contact.</p>
        <p>Approximately 80% of COVID-19 cases are mild or oligosymptomatic.<sup><xref rid="B9" ref-type="bibr">9</xref></sup> A recent study shows that 20% required hospital care, with 5% to 15% of these being treated in intensive care units requiring ventilatory support. Mortality for these patients can reach up to 80%.<sup><xref rid="B9" ref-type="bibr">9</xref></sup>SARS-CoV-2 can be transmitted from person to person (contact with hands, cough, or saliva droplets) or through surfaces and objects contaminated by the virus.<sup><xref rid="B10" ref-type="bibr">10</xref></sup> On May 16, 2020, more than 4,605,673 people had been diagnosed with COVID-19, and there were 310,180 deaths worldwide. In Brazil, by May 16, 2020, 222,877 cases had been recorded, with 15,046 deaths.<sup><xref rid="B11" ref-type="bibr">11</xref></sup> Among the measures to prevent COVID-19 infection, individuals are recommended to clean their hands, surfaces, and objects with water and soap or hand sanitizer. Other indications include avoiding contact with eyes, nose, and mouth; permanent use of a facemask; maintaining healthy eating and sleep habits; and social isolation and distancing.<sup><xref rid="B12" ref-type="bibr">12</xref></sup></p>
        <p>The increase in the number of deaths, in the context of the pandemic, can aggravate users&#8217; fear of leaving social isolation and seeking medical assistance and essential services. This could delay the demand for health services affecting the underlying disease. It is interesting to note that almost 89% of our sample did not have medical follow-up, and in a similar frequency (87%) the nature of the CPA was the clinical cause.</p>
        <p>Gonzales-Olmo et al.,<sup><xref rid="B13" ref-type="bibr">13</xref></sup> in a recent study, with data from the population of Madrid, demonstrated high levels of individual self-perception of greater vulnerability in relation to COVID-19 infection when seeking dental care, which is considered an essential health service. Thus, the researchers observed that the sample of individuals over 60 years of age with systemic diseases avoided dental care most of the time.<sup><xref rid="B13" ref-type="bibr">13</xref></sup></p>
        <p>In accordance with our results, Holmes et al. (2020) indicated that there was a structural break in the time series of weekly admissions deferred annually according to emergency services in the United Kingdom between September 2019 and April 2020.<sup><xref rid="B14" ref-type="bibr">14</xref></sup>These researchers observed the period of time corresponding to September 2019 and April 2020.</p>
        <p>Scales for assessing individuals&#8217; fear have been developed and are in the validation phase (such as the &#8220;Fear of COVID-19 Scale&#8221;) in order to assess this emotion. New studies are expected to assess the context of the pandemic in this regard, monitoring fear at the expense of not seeking essential health services, improving quality of life, and delaying mortality due to causes that do not involve COVID-19.<sup><xref rid="B15" ref-type="bibr">15</xref>-<xref rid="B17" ref-type="bibr">17</xref></sup></p>
        <p>Julia et al.<sup><xref rid="B18" ref-type="bibr">18</xref></sup> report on the reorganization of the health service in France during the pandemic. Important investments have been made in terms of teleconsultations for the follow-up of patients with COVID-19, but the most vulnerable population with difficulties in accessing the internet and digital technologies or those with language barriers were left without adequate assistance. In addition, the available hospital beds have been drastically reduced, and primary health care professionals have thus had to deal with emergencies due to chronic diseases.<sup><xref rid="B18" ref-type="bibr">18</xref></sup> Home visits have been divided according to patients with and without COVID-19, leading to service overload. A flow for primary care has now been adopted for patients with chronic diseases, in order to avoid delays for outpatient control.<sup><xref rid="B17" ref-type="bibr">17</xref></sup></p>
        <p>In Belo Horizonte, there has been a reduction in demand from the population for care in the Basic Health Units and the Emergency Care Units. During the first four months of 2019, 1,478,905 people were attended; during the same period of 2020, this number was 1,215,543, which represents an 18% reduction.<sup><xref rid="B19" ref-type="bibr">19</xref></sup> Thus, it is important to monitor the management of chronic diseases and promote educational actions so that the population understands the importance of health care follow-up and the regular use of necessary medicines. Accordingly, the Municipal Health Department of Belo Horizonte has updated the flow of care in primary health care.<sup><xref rid="B19" ref-type="bibr">19</xref>,<xref rid="B20" ref-type="bibr">20</xref></sup></p>
        <p>Souza et al.<sup><xref rid="B21" ref-type="bibr">21</xref></sup> report on the primary health care provided by SUS in Brazil and on the investments that have been destined for acquisition of equipment and expansion of hospital beds for patients with COVID-19. They reinforce the need to strengthen primary care as an instrument to prevent collapse in the health system, avoiding deaths due to COVID-19 and chronic diseases.<sup><xref rid="B21" ref-type="bibr">21</xref></sup> It is necessary to reflect on how to find the balance so that health actions are not paralyzed during the pandemic.</p>
        <p>The Municipal Health Department of Belo Horizonte has carried out initiatives such as training through web conferences, web classes, and discussion of clinical cases and technical notes for care and flow of patients with COVID-19, establishing partnerships for online care and assisting patients risk groups. At the same time, it has been taking measures to adapt emergency services and primary health care, seeking to avoid overloading services and promoting better care for patients with and without COVID-19.<sup><xref rid="B20" ref-type="bibr">20</xref></sup></p>
        <p>The increased numbers of home deaths have aroused the attention of health managers, and the idea is to reinforce the importance of outpatient control of chronic diseases and to clarify adopted safety measures to the population regarding clinical complications not related to COVID-19 during the pandemic.</p>
        <p>It is a favorable moment to reinvent the relationship between users and primary health care professionals, seeking greater closeness to establish bonds, strengthen the importance of controlling chronic diseases and avoiding unnecessary deaths. It is also necessary to implement measures to improve death surveillance. Primary health care services should organize assistance and patient flows in order to ensure adequate care for patients with and without COVID-19.</p>
        <p>As a study limitation, we point out the high percentage of individuals for whom it was not possible to collect information about the existence of comorbidities (38.5% of the sample) due to the lack of information from the interviewed relatives or friends, which may have underestimated the values presented.</p>

        <title>Conclusion</title>
        <p>The results point to an increase in the number of home deaths due to CPA notified by SAMU in March 2020 in relation to March 2018 and March 2019 in Belo Horizonte, Minas Gerais. It is necessary to carry out new studies with a longitudinal design in order to monitor the increase in mortality of health system users and analyze its causal relationships in order to avoid deaths due to other diseases that do not involve COVID-19.</p>
