MEDICAL RESIDENCE IN ORTHOPEDICS AND TRAUMATOLOGY - NATIONAL OVERVIEW AND ANALYSIS OF EVALUATION CONCORDANCE BETWEEN CNRM/SBOT DURING THE COVID-19 PANDEMIC.

Objective: Describe the national scenario of the orthopedics and traumatology Medical Residency Program (MRP) in 2020/2021, showing the distribution of vacancies by states and regions of Brazil, the number of residents and the percentage of agreement between the accredited services that offer the program by the Brazilian Society of Orthopedics and Traumatology (SBOT) and by the National Commission for Medical Residency linked to the Ministry of Education (CNRM/MEC). Methods: This is a descriptive, cross-sectional study. Data from the CNRM and SBOT system referring to residents attending orthopedics and traumatology Programs in 2020/2021 were analyzed. Results: In the analyzed period, there were 2.325 medical residents in orthopedics and traumatology in vacancies authorized by the CNRM/MEC in Brazil. The southeast region was predominant, with 57.2% of vacancies, totaling 1.331 residents. Compared to other regions, the south region with 16.9% (392), the northeast with 15.1% (351), the midwest with 7.7% (180), and the north with 3.1% (71). In addition, there was an accreditation agreement of 53.8% in evaluating services between the SBOT and CNRM, with distinctions among the states. Conclusion: The analysis showed differences between regions and states, considering the vacancies of PRM in orthopedics and traumatology and the concordance of evaluations by institutions accredited by MEC and SBOT. It is aim to work together with a view to qualifying and expanding residency programs for the training of specialist physicians, in accordance with the needs of the public health system and adequate medical practice, is necessary. The analysis during the pandemic period, associated with the restructuring of several health services, demonstrates the stability of the specialty in adverse scenarios.

High prevalence of mental disorder symptoms among medical and other health specialties residents during the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic put healthcare professionals, including residents (postgraduate trainees of health professions), under intense physical and psychological stress, hence at risk for mental disorders. We evaluated the prevalence of mental disorders among healthcare residents during the pandemic. METHODS: From July to September 2020, residents in medicine and other healthcare specialties in Brazil were recruited. The participants completed electronic forms with validated questionnaires (DASS-21, PHQ-9, BRCS) to screen for depression, anxiety, and stress, and to evaluate resilience. Data on potential predisposing factors for mental disorders were also collected. Descriptive statistics, chi-squared, students t, correlation and logistic regression models were applied. The study received ethical approval, and all participants provided informed consent. RESULTS: We included 1313 participants (51.3% medical; 48.7% nonmedical) from 135 Brazilian hospitals; mean (SD) age: 27.8 (4.4) years; 78.2% females; 59.3% white race. Of all participants, 51.3%, 53.4% and 52.6% presented symptoms consistent with depression, anxiety, and stress, respectively; 61.9% showed low resilience. Nonmedical residents exhibited higher anxiety compared to medical residents (DASS-21 anxiety score, mean difference: 2.26; 95% CI: 1.15-3.37; p < 0.001). In multivariate analyses, having any pre-existent, nonpsychiatric chronic disease was associated with higher prevalence of symptoms indicative of depression (odds ratio, OR: 2.05; 95% CI: 1.47-2.85, on DASS-21 | OR: 2.26; 95% CI: 1.59-3.20, on PHQ-9), anxiety (OR: 2.07; 95% CI: 1.51-2.83, on DASS-21), and stress (OR: 1.53; 95% CI: 1.12-2.09, on DASS-21); other predisposing factors were identified; by contrast, high resilience (BRCS score) was protective against symptoms of depression (OR 0.82; 95% CI: 0.79-0.85, on DASS-21 | OR 0.85; 95% CI: 0.82-0.88, on PHQ-9), anxiety (OR 0.90; 95% CI: 0.87-0.93, on DASS-21), and stress (OR 0.88; 95% CI: 0.85-0.91, on DASS-21); p < 0.05 for all outcomes. CONCLUSIONS: We found a high prevalence of mental disorder symptoms among healthcare residents during COVID-19 pandemic in Brazil. Nonmedical residents exhibited higher levels of anxiety than medical ones. Some predisposing factors for depression, anxiety and stress among residents were identified.

High prevalence of burnout syndrome among medical and nonmedical residents during the COVID-19 pandemic.

BACKGROUND: Since the beginning of the COVID-19 pandemic, health professionals have been working under extreme conditions, increasing the risk of physical and mental illness. We evaluated the prevalence of burnout and its associated factors among postgraduate student residents in health professions during the global health crisis. METHODS: Healthcare residents were recruited from all across Brazil between July and September 2020 through digital forms containing instruments for assessing burnout (Oldenburg Burnout Inventory (OLBI)), resilience (brief resilient coping scale (BRCS)) and anxiety, stress and depression (depression, anxiety and stress scale (DASS-21) and Patient Health Questionnaire (PHQ-9)). Additionally, the relationships between burnout and chronic diseases, autonomy and educational adequacy in the residency programme, personal protective equipment (PPE), workload and care for patients with COVID-19 were evaluated. The chi-square test, Student's t test, Pearson's correlation test and logistic regression were performed. RESULTS: A total of 1,313 participants were included: mean (standard deviation) age, 27.8 (4.4) years; female gender, 78.1%; white race, 59.3%; and physicians, 51.3%. The overall prevalence of burnout was 33.4%. The odds (odds ratio [95% confidence interval]) of burnout were higher in the presence of pre-existing diseases (1.76 [1.26-2.47]) and weekly work > 60 h (1.36 [1.03-1.79]) and were lower in the presence of high resilience (0.84 [0.81-0.88]), autonomy (0.87 [0.81-0.93]), and educational structure (0.77 [0.73-0.82]), adequate availability of PPE (0.72 [0.63-0.83]) and non-white race (0.63 [0.47-0.83]). Burnout was correlated with anxiety (r = 0.47; p < 0.05), stress (r: 0.58; p < 0.05) and depression (r: 0.65; p < 0.05). CONCLUSIONS: We observed a high prevalence of burnout among residents during the COVID-19 pandemic. Individual characteristics and conditions related to the work environment were associated with a higher or lower occurrence of the syndrome.

Overview of general surgery medical residency programs and prerequisite program in basic surgical area in Brazil: Historical review and update.

OBJECTIVE: to describe vacancy regulation process by adding, describing the panorama of the General Surgery Residency Program (PRMCG) and the Basic Surgical Prerequisites Program (PRACB). METHOD: descriptive, quali-quantitative, cross sectional study conducted from document analysis from National Commission of Medical Residency (CNRM). RESULTS: in 2018, after evaluation of the General Surgery Services for adequacy of the number of vacancies (DS), the PRACB was instituted as a modality of access to surgical specialties until definitive change in the time of the formation of the general surgeon for three years, in 2022. In the first addition of vacancies in 2018, 127 PRMCG were authorized with 736 vacancies of R1 and 290 PRACB (2 years) with 1.286 vacancies offered for R1. In the second addition in 2021, 423 PRM were authorized with 1.564 R1 vacancies in PRMCG. DISCUSSION: the regulation of the offer of vacancies for the formation of specialties in Brazil should align the evaluation of practice scenarios with the profile of skills. The PRACB modality was instituted for a certain time for budgetary preparation and practice scenarios until the complete transition to training in 3 years. CONCLUSION: Brazil by 2018 was the only country to grant the Board Certification to General Surgeon with only 2 years of training. After a transitional period the same analysis methodology for adding and regulating vacancies was applied to services.

Osteoporotic hip fracture-Comorbidities and factors associated with in-hospital mortality in the elderly: A nine-year cohort study in Brazil.

INTRODUCTION: The aim of the study was to identify factors associated with the causes of in-hospital morbidity and mortality in an elderly Brazilian population due to osteoporotic hip fractures. METHOD: Retrospective cohort study involving a population over 60 years of age admitted to hospital due to osteoporotic hip fractures and followed up from hospitalization to outcome (discharge or mortality) from 2010 to 2018, in a public hospital in Brasília, the capital of Brazil. Multivariate analysis was performed using the Poisson regression model with a robust variance, observing the hierarchical model proposed and the receiver operating characteristic (ROC) curve to obtain the cutoff point for mortality incidence in relation the total length of hospital stay. Significance level was set as p < 0.05. The analyses were conducted using the SAS 9.4 software. RESULT: The mean hospital mortality rate among the 402 patients involved was 18.4%, and the associations made with the outcome mortality were per relevance: respiratory infection, age over 90 years, high preoperative cardiovascular risk, chronic obstructive pulmonary disease (COPD) as comorbidity, serum hemoglobin level ≤ 10 and other infections. Mortality also showed association with longer total length of hospital stay, as well as with prolonged postoperative period. CONCLUSION: Hip fractures in the elderly due to osteoporosis indicate a relationship between the sicker profile of the aging elderly population and the prevalence of chronic diseases strongly associated with in-hospital infections, contributing to increased mortality. There were fewer early interventions, and mortality was also associated with prolonged postoperative period. The aim of this study was not to compare independent variables with each other, but suggests the relationship between the presence of comorbidities, which predisposes to the development of infections, directly linked to mortality.

RESUMO Objetivo: descrever o contexto do processo de construção e implantação da Matriz de Competências da Cirurgia Geral com tempo de formação em 3 anos e o processo sobre a regulação de vagas, por aditamento, descrevendo o panorama dos Programas de Residência Médica em Cirurgia Geral (PRMCG) e do Programa de Pré-Requisito em área cirúrgica básica (PRACB). Método: estudo descritivo, quanti-qualitativo, transversal, realizado a partir da análise documental das atas, súmulas, nota técnica, resoluções e atos autorizativos da Comissão Nacional de Residência Médica (CNRM), bem como do Diagnóstico Situacional (DS), considerando a matriz de competências da especialidade em sua implementação, por meio de dados coletados no Sistema da Comissão Nacional de Residência Médica (SisCNRM), no portal eletrônico do Ministério da Educação (MEC). Resultado: em 2018, após metodologia de avaliação dos serviços para adequação do número de vagas (DS), foi instituído o PRACB como uma modalidade de acesso às especialidades cirúrgicas e de adaptação dos serviços formadores, até mudança definitiva no tempo de formação do Cirurgião Geral, para três anos, em 2022. No primeiro aditamento de vagas, em 2018, foram autorizados 127 PRMCG (3 anos) com 736 vagas de R1 e 290 pracb (2 anos) com 1286 vagas ofertadas para R1. No segundo aditamento, em 2021, foram autorizados 423 PRM com 1564 vagas de R1 em PRMCG. Atualmente 2495 médicos residentes estão em curso nos PRMCG e 50 (R2) estão concluindo o pracb. A maior concentração de PRM e médicos residentes encontra-se no Estado de São Paulo, em oposição a Região Norte. Discussão: a regulação da oferta de vagas para a formação de especialistas no Brasil deve alinhar a avaliação dos cenários de prática ao perfil das competências para a Especialidade como as necessidades de médicos especialistas indicada pelo perfil socioepidemiológico da população. Contudo, as instituições devem possuir estrutura compatível para a aquisição de competências necessárias ao especialista e dotação orçamentária para o financiamento do processo. A modalidade PRACB foi instituída por tempo determinado para a preparação orçamentária e dos cenários de prática, até a transição completa para a formação em 3 anos, possibilitando ao médico residente, enquanto vigente, acesso às especialidades cirúrgicas. Conclusão: O Brasil até 2018 era o único país a conceder o Título de Especialista em Cirurgia Geral com um tempo exíguo de treinamento - 2 anos. Após um período de transição, a mesma metodologia de análise para aditamento e regulação da oferta de vagas foi aplicada aos serviços. A partir de 2023, o PRMCG com duração de 3 anos, será a modalidade de formação que confere o título de especialista em Cirurgião Geral pela CNRM, promovendo qualificação profissional para assistência e cenários de prática compatíveis com a aquisição de competências. .
