Competency matrix related to Covid-19: contributions from students and residents / Matriz de competência relacionada à Covid-19: contribuições de estudantes e residentes

Abstract: Introduction: Competency-based education has been discussed under the new perspective of the COVID-19 pandemic. The need for social distancing had effects on student activities and educational institutions needed to reflect and redesign the teaching-learning process. It was necessary to incorporate contents related to COVID-19 into the medical training programs and to adapt the teaching tools. Therefore, it is necessary that training be mediated by a collective construction of the competency matrix with the participation of the subjects involved in the process. Objective: This project aims to present the reconstruction of the curriculum in cardiology by observing the collaboration of the students and residents. Method: Exploratory study, involving 13 undergraduate medical students and eight medical residents from the institution's cardiology program, who comprised the "Students and residents' panel". Consensus was reached among the panelists through the Delphi methodology. The first version of the matrix was prepared by the research team and sent, together with the FICF, containing 16 items aimed at COVID-19 content to be achieved at the cardiology internship and residency. The participants attributed their degree of agreement for each proposed item and after returning them, the data were tabulated, stored in an Excel spreadsheet and percentages for each item were calculated and presented in a descriptive manner. Result: The panel consisted of 19 participants. Of the 21 invited, 02 participants did not answer the online questionnaire and were excluded. The initial version of the matrix reached a consensus in the first round, with the lowest agreement rate being 71% in the internship matrix and 89.5% in the residency matrix. Both matrices showed high levels of agreement. There were no disagreements or suggestions for new items for the matrix. Conclusion: The students and residents' engagement in the pedagogical process may contribute to a better understanding of the competencies for their training and bring sustainable changes to the curriculum.

Resumo: Introdução: A educação baseada em competências vem sendo discutida sob a nova perspectiva da pandemia da Covid-19. A necessidade do distanciamento social trouxe repercussão nas atividades estudantis, e as instituições de ensino precisaram refletir e redesenhar o processo de ensino-aprendizagem. Houve a necessidade de inserção de conteúdos relacionados à Covid-19 nos programas de capacitação médica e a adaptação das ferramentas pedagógicas. Portanto, é necessário que a formação seja mediada por uma construção coletiva da matriz de competências com participação dos sujeitos envolvidos no processo. Objetivo: Este projeto visa apresentar a reconstrução da matriz de competências em cardiologia observando a colaboração do estudante e residente. Método: Trata-se de um estudo exploratório envolvendo 13 graduandos do curso de Medicina e oito residentes médicos do programa de cardiologia da instituição, os quais compuseram o "Painel de estudantes e residentes". Obteve-se o consenso entre os painelistas por meio da metodologia Delphi. A primeira versão da matriz foi elaborada pela equipe de pesquisa e enviada, com o TCLE, contendo 16 itens voltados para conteúdos sobre a Covid-19 a serem alcançados no internato e na residência em cardiologia. Os participantes atribuíram o grau de concordância a cada item proposto, sendo os dados apresentados de forma descritiva e com proporção de concordância. Resultados: O painel final foi formado por 19 integrantes. Dentre os 21 convidados, dois foram excluídos por não responderem ao questionário. A versão inicial da matriz obteve consenso na primeira rodada, sendo a menor taxa de concordância de 71% na matriz do internato e 89,5% na matriz da residência. Ambas as matrizes apresentaram índices elevados de concordância. Não houve discordâncias nem sugestões de novos itens para a matriz. Conclusão: O engajamento de estudantes e residentes no processo pedagógico pode contribuir para melhor compreensão sobre as competências para sua formação e promover mudanças sustentáveis no currículo.

Myocardial fibrosis detected by cardiac CT predicts ventricular fibrillation/ventricular tachycardia events in patients with hypertrophic cardiomyopathy.

BACKGROUND: Myocardial fibrosis (MF) occurs in up to 80% of subjects with asymptomatic or mildly symptomatic hypertrophic cardiomyopathy (HCM) and can constitute an arrhythmogenic substrate for re-entrant, life-threatening ventricular arrhythmias in predisposed persons. OBJECTIVE: The aim was to investigate whether MF detected by delayed enhancement cardiac CT is predictive of ventricular tachycardia (VT) and fibrillation (VF) that require appropriate therapy by an implantable cardioverter defibrillator (ICD) in patients with HCM. METHODS: Twenty-six patients with HCM with previously (for at least 1 year) implanted ICD underwent MF evaluation by cardiac CT. MF was quantified by myocardial delayed enhanced cardiac CT. Data on ICD firing were recorded every 3 months after ICD implantation. Risk factors for sudden cardiac death in patients with HCM were evaluated in all patients. RESULTS: MF was present in 25 of 26 patients (96%) with mean fibrosis mass of 20.5 ± 15.8 g. Patients with appropriate ICD shocks for VF/VT had significantly greater MF mass than patients without (29.10 ± 19.13 g vs 13.57 ± 8.31 g; P = .01). For a MF mass of at least 18 g, sensitivity and specificity for appropriate ICD firing were 73% (95% CI, 49%-88%) and 71% (95% CI, 56%-81%), respectively. Kaplan-Meier curves indicated a significantly greater VF/VT event rate in patients with MF mass ≥18 g than in patients with MF <18 g (P = .02). In the Cox regression analysis, the amount of MF was independently associated with VF/VT in ICD-stored electrograms. CONCLUSION: The mass of MF detected by cardiac CT in patients with HCM at high risk of sudden death was associated with appropriate ICD firings.

Fibrose miocárdica em pacientes com cardiomiopatia hipertrófica com alto risco para morte súbita cardíaca / Myocardial fibrosis in patients with hypertrophic cardiomyopathy and high risk for sudden death

FUNDAMENTO: A estratificação de risco para morte súbita na cardiomiopatia hipertrófica (CMH), continua a ser um verdadeiro desafio devido à grande heterogeneidade da sua apresentação, em que a maioria dos indivíduos permanecem assintomáticos por toda sua vida e outros apresentam a morte súbita como primeiro sintoma. Recentes trabalhos vêm sugerindo que a fibrose miocárdica pode constituir-se em um importante substrato para as arritmias ventriculares malignas, responsáveis pela morte súbita nesta doença. OBJETIVO: Avaliação da prevalência e quantificação da fibrose miocárdica (FM), em pacientes com CMH com alto risco ou recuperados de morte súbita, portadores de cardiodesfibrilador implantável (CDI). MÉTODOS: Vinte e oito pacientes com CMH portadores de CDI foram submetidos à tomografia computadorizada com múltiplos detectores, para realização da técnica de realce tardio, e avaliação da fibrose miocárdica. RESULTADOS: 96 por cento dos pacientes apresentavam fibrose miocárdica (20,38 ± 15,55 gramas) correspondendo a 15,96 ± 10,20 por cento da massa miocárdica total. A FM foi significativamente mais prevalente que os demais fatores de risco clássicos para morte súbita. CONCLUSÃO: Concluímos que existe uma alta prevalência de fibrose miocárdica em pacientes com cardiomiopatia hipertrófica de alto risco ou recuperados de morte súbita, como neste grupo - portadores de cardiodesfibrilador implantável. A maior prevalência da fibrose miocárdica comparada aos fatores de risco de pior prognóstico levantam a hipótese de que a fibrose miocárdica possa ser um importante substrato potencialmente necessário na gênese das arritmias desencadeadoras da morte súbita.

BACKGROUND: The stratification of risk for sudden death in hypertrophic cardiomyopathy (HCM) continues to be a true challenge due to the great heterogeneity of this disease's presentation, as most individuals remain asymptomatic during their entire lives and others present sudden death as first symptom. Recent studies have suggested that myocardial fibrosis may represent an important substrate for the malignant ventricular arrhythmias, that are responsible for the cases of sudden death related to this disease. OBJECTIVE: To assess the prevalence and quantification of myocardial fibrosis (MF) in hypertrophic cardiomyopathy (HCM) patients with implantablecardioverter - defibrillator (ICD) indicated due to their high risk or recovered from cardiac sudden death. METHODS: Twenty-eight HCM patients with ICD were submitted to multidetector computed tomography to assess myocardial fibrosis by delayed enhancement technique. RESULTS: Myocardial fibrosis was present in 96 percent of these HCM patients with (20.38 ± 15.55 g) comprising 15.96 ± 10.20 percent of the total myocardial mass. MF was observed in a significantly higher prevalence as compared to other classical risk factors for sudden death. CONCLUSION: It is possible to conclude that there is a high prevalence of myocardial fibrosis in hypertrophic cardiomyopathy patients with high-risk or recovered from cardiac sudden death, like those with clinical indication to implantable cardioverter -defibrillator. The higher prevalence of myocardial fibrosis in comparison to classical risk factors of worse prognosis raise the hypothesis that the myocardial fibrosis may be an important substrate in the genesis of lifethreatening arrhythmias in these high risk HCM population.
