Planning feasible and efficient operational scenarios for a university hospital through multimethodology.

The COVID-19 pandemic required managerial and structural changes inside hospitals to address new admission demands, frequently reducing their care capacity for other diseases. In this regard, this study aims to support the recovery of hospital productivity in the post-pandemic context. The major challenge will be to make use of all the resources the institution has obtained (equipment, beds, temporarily hired human resources) and to increase production to meet the existing repressed demand. To support evidence-based decision-making at a major university hospital in Rio de Janeiro, hospital managers and operations research analysts designed an approach based on multiple methodologies. Besides multimethodology, one important novelty of this study is the application of a productivity frontier function to future scenario planning through the quantitative DEA methodology. Concept maps were used to structure the problem and emphasize stakeholders' perspectives. In sequence, data envelopment analysis (DEA) was applied, as it combines benchmarking best practices and assigns weights to inputs and outputs. To guarantee that the efficiency measurement considers all inputs and outputs before any inclusion of expert judgment, the scope was redirected to full dimensional efficient facet, if any, or to maximum efficient faces. The results indicate that production scenarios proposed by stakeholders based on the Ministry of Health parameters overestimate the viable production framework and that the scenario that maintains temporary human resource contracts is more compatible with quality in health provision, teaching, and research. These findings will serve as a basis for decision-making by the governmental agency that provided temporary contracts. The present methodology can be applied in different settings and scales.

Efficiency and sustainability of public health spending in Brazil

Objective: This paper discusses issues related to the efficiency and sustainability of public spending on health in Brazil. Despite the achievements of recent decades, the Unified Health System (SUS) faces structural challenges with consequences on the access to public health services and on the financial protection of the population. Methods: The paper provides a brief overview of the public healthcare financing in Brazil over the last ten years and presents an efficiency analysis of the SUS public health spending, using data envelopment analysis (DEA) models for the years of 2013 and 2017. Results: In terms of public spending, the paradox that Brazil spends little but poorly on health still persists. Public expenditures on health are relatively lower than those observed in countries with health systems with similar characteristics, but public expenditures per capita grow at rates higher than the growth of gross domestic product (GDP) per capita. In terms of efficiency of public health spending, the analysis shows that there is potential to increase the efficiency of the SUS. In 2017, these inefficiencies amounted R$ 35.8 billion. In general, SUS primary healthcare (APS) is more efficient (63% and 68% in 2013 and 2017) than high and medium complexity care (MAC) (29% and 34% in the same years, respectively). Conclusion: Improving the efficiency of public spending on health is particularly important in the current context of low economic growth and strong fiscal constraints in the post-pandemic environment. Efficiency gains can be achieved with: (i) scale gains in the structure and operation of hospitals, (ii) integration of care in health care networks, (iii) increased density and better distribution of the health workforce, (iv) change in mechanisms and incentives to link payments to providers and professionals to health outcomes, with the PHC as the organizer of the system, (v) innovations in the management of health service providers, with an emphasis on public partnership models and private companies (PPPs) . The consolidation of the SUS depends on public policies to improve the efficiency and quality of services provided to the population.

Eficiência e sustentabilidade do gasto público em saúde no Brasil / Efficiency and sustainability of public health spending in Brazil

Objetivo: Este artigo discute questões relativas à eficiência e à sustentabilidade do gasto público com saúde no Brasil. A despeito das conquistas das últimas décadas, o Sistema Único de Saúde (SUS) enfrenta desafios estruturais com consequências no acesso aos serviços públicos de saúde e na proteção financeira da população. Métodos: O artigo traça um breve panorama do financiamento da saúde no Brasil nos últimos 10 anos e apresenta análise da eficiência do gasto público em saúde utilizando modelos de análise envoltória de dados (data envelopment analysis ­ DEA) para os gastos com o SUS nos de 2013 e 2017. Resultados: Do ponto de vista do financiamento do sistema público de saúde, persiste o paradoxo de que o Brasil gasta pouco, mas gasta mal. Os gastos públicos com saúde são relativamente menores que os observados em países com sistemas de saúde com caraterísticas semelhantes, porém os gastos públicos per ca pita crescem a taxas maiores do que o crescimento do Produto Interno Bruto (PIB) per capita. Do ponto de vista da eficiência, a análise demonstra que há potencial de aumentar a eficiência do SUS. Apenas em 2017 essas ineficiências somavam R$ 35,8 bilhões. De forma geral, a atenção primária à saúde (APS) do SUS tem eficiência maior (63% e 68% em 2013 e 2017) do que a atenção de alta e média complexidade (MAC) (29% e 34% nos mesmos anos, respectivamente). Conclusão: Melhorar a eficiência do gasto público com saúde é particularmente importante no contexto atual de baixo crescimento econômico e fortes restrições fiscais no ambiente pós-pandemia. Ganhos de eficiência podem ser alcançados com: (i) ganhos de escala na estrutura e operação dos hospitais, (ii) integração do cuidado em redes de atenção à saúde, (iii) aumento da densidade e melhor distribuição da força de trabalho em saúde, (iv) mudança nos mecanismos e incentivos para vincular os pagamentos aos provedores e profissionais aos resultados de saúde, tendo a APS como organizadora do sistema, (v) inovações na gestão dos provedores de serviços de saúde, com ênfase em modelos de parcerias público-privadas (PPPs). A consolidação do SUS depende de políticas públicas que melhorem a eficiência e a qualidade dos serviços prestados à população.

Do 'Mais Médicos' à pandemia de Covid-19: duplo negacionismo na atuação da corporação médica brasileira / From 'More Doctors' to the COVID-19 pandemic: dual denialism in the Brazilian medical corporation's performance

RESUMO O ensaio analisa a dinâmica de atuação corporativa da medicina brasileira na pandemia de Covid-19, de março de 2020 a julho de 2021, a partir de documentos e material institucional das entidades médicas nacionais, de organizações estudantis e de coletivos de médicos de expressão nacional, além de matérias jornalísticas e publicações da literatura científica sobre o tema. O período é marcado pela politização da agenda corporativa e pelo alinhamento com os discursos negacionistas do governo de Jair Bolsonaro. Argumenta-se que esse processo é resultado de uma politização anterior: o embate contra o Programa Mais Médicos no período de 2013, ano de seu lançamento, a 2019, quando foi encerrado pelo governo. Os dois momentos históricos revelam um duplo negacionismo da corporação médica - acentuando fragilidades, contradições e dilemas da encruzilhada da profissão - que exigirá diálogos internos e com a sociedade, para novos consensos da identidade corporativa e do projeto profissional da medicina. A compreensão dos entrelaçamentos, disputas e sentidos das dinâmicas e rumos da atuação corporativa da medicina permitem identificar problemas estruturais de raízes políticas que impedem maiores avanços na consolidação do Sistema Único de Saúde.

ABSTRACT This essay analyzes the dynamics of Brazilian medical practice's corporate action in the COVID-19 pandemic, from March 2020 to July 2021, from documents and institutional material of national medical entities, student organizations, groups of nationally reputed physicians, and journalistic articles and scientific literature publications on the subject. This period is marked by the politicization of the corporate agenda and the alignment with the denialist discourses of Jair Bolsonaro's administration. It is argued that this process stems from a previous politicization: the clash against the More Doctors Program from 2013, the year of its launch, to 2019, when the Government deactivated it. The two historical moments reveal the dual denialism of the medical corporation, emphasizing weaknesses, contradictions, and dilemmas of the profession's crossroads, which will require internal and social dialogues for a new consensus on corporate identity and the professional project of Medicine. Understanding the intertwining, disputes, and meanings of the dynamics and directions of the corporate action of Medicine allows identifying structural problems of political roots that prevent further advances in the consolidation of the Unified Health System.

Neumonía Intersticial con características autoinmunes (IPAF): Reporte de casos / Interstitial pneumonia with autoimmune features (IPAF): Case reports

IPAF agrupa individuos con EPID y otras características clínicas, serológicas o pulmonares que derivan de una condición autoinmune sistémica subyacente, pero no cumplen con los criterios reumatológicos actuales para una ETC. La EPID, manifestación clínica frecuente de las ETC, puede aparecer en el contexto de una ETC conocida pero no es infrecuente que sea la primera y única manifestación de un ETC oculta. Identificar una ETC subyacente en pacientes que presentan con compromiso intersticial inicial puede ser un desafío; tales evaluaciones pueden optimizarse mediante un enfoque multidisciplinario. Presentamos el caso de tres pacientes, de diferente presentación, evolución y tratamiento, todos caracterizados hasta la fecha como IPAF.

IPAF groups individuals with ILD and other clinical, serologic, or pulmonary manifestations with an underlying systemic autoimmune condition, but do not meet current rheumatologic criteria for a CTD. ILD is a frequent clinical manifestation of CTDs; may appear in the context of a well known CTD but is often the first and only manifestation of an unknown CTD. Identifying an underlying CTD in patients presenting with initial interstitial involvement can be challenging; such evaluations can be optimized using a multidisciplinary approach. We present the case of three patients, of different presentation, evolution and treatment, all characterized to date as IPAF.

Acute response of refeeding in tambaqui submitted to long-term fasting / Respostas agudas da realimentação em tambaquis submetidos ao jejum prolongado

This study aimed evaluate energetic mobilization in tambaqui submitted to fasting, after a one-day refeeding. 120 tambaqui juveniles were distributed in 12 310L polyethylene boxes. Three treatments were evaluated: Control (14 days of feeding); Fasting for 14 days; and Refeeding (13 days fasting and one day of feedback). After the experimental period, the fish were anesthetized with eugenol for blood collection and serum and plasma were used to measure glucose, triglycerides, cholesterol and serum protein. Subsequently, fish were euthanized to remove liver and mesenteric fat and were used to determine hepatic glycogen and lipid and mesenteric fat index. The results were submitted to ANOVA and the means compared by Tukey test when statistical significance was observed (P <0.05). Glucose, triglycerides and serum protein decreased after fasting, differing statistically with the control. Refeeding resulted in the recovery of three blood indicators. Liver analysis shows glycogen was consumed intensely during fasting and partially recovered after refeeding, when compared to control group. The results obtained in this study suggest that the 14-day fast was not harmful to the fish and the tambaqui are able to quickly adjust their metabolism according to their nutritional status.(AU)

Este estudo objetivou avaliar a mobilização energética em tambaqui submetido ao jejum, após a realimentação de um dia. 120 juvenis de tambaqui foram distribuídos em 12 caixas de polietileno de 310L. Foram avaliados três tratamentos: grupo controle (14 dias de alimentação); Jejum de 14 dias; e realimentado (13 dias em jejum e um dia de realimentação). Após o período experimental, os peixes foram anestesiados com eugenol para coleta de sangue e o soro e o plasma foram utilizados para dosagem de glicose, triglicerídeos, colesterol e proteína sérica. Posteriormente, os peixes foram eutanasiados para remoção de fígado e gordura mesentérica e foram usados ​​na determinação de glicogênio e lipídio hepático e índice de gordura mesentérica. Os resultados foram submetidos à ANOVA e as médias comparadas pelo teste de Tukey quando observada significância estatística (P <0,05). Glicose, triglicérides e proteína sérica reduziram após o jejum, diferindo estatisticamente com o controle. Já a realimentação resultou na recuperação dos três indicadores sanguíneos. A análise no fígado mostra que o glicogênio foi consumido intensamente durante o jejum e recuperou parcialmente após a realimentação, quando comparados ao grupo controle. Os resultados obtidos neste estudo sugerem que o jejum de 14 dias não foi prejudicial aos peixes e os tambaqui são capazes de ajustar rapidamente seu metabolismo de acordo com seu estado nutricional.(AU)

Biological index based on epiphytic diatom assemblages is more restrictive than the physicochemical index in water assessment on an Amazon floodplain, Brazil.

Canadian Water Quality Index (CWQI) provides protection for freshwater life promoting healthy ecosystems and safeguarding human health. Biological Diatom Index (BDI) was developed to indicate the ecological status and water quality of freshwater systems. This paper evaluates the relations between the two different indices. During rising and falling, water samples were taken in the Curuai Floodplain, Brazil. CWQI was calculated using 14 physicochemical parameters and 1 microbiological parameter. The limits were established according to freshwater quality conditions and standards based on water use classes 1 and 2 determined in CONAMA 357 legislation and British Columbia. Canadian Water Quality Index categorization ranged from "marginal" to "excellent," most sampling units were "good" (71%), followed by "fair" (12%) and "excellent" (12%) water quality. Total phosphorus (38 times), chlorophyll a (20), dissolved oxygen (10), and total organic carbon (10) were the parameters that presented the most non-compliance values. Encyonema silesiacum (14%), Gomphonema parvulum (13%), and Navicula cryptotenella (12%) were the main taxa in the rising period, while G. lagenula, E. silesiacum, and Fragilaria capucina were the main taxa during the falling period. BDI ranges from I to V water quality classes. We observed "poor" to "very good" ecological status, with most sampling units "moderate" (52%) and "good" (29%). Water quality for class 2 was better than water quality for class 1, as the limits of the parameters evaluated were more restrictive in class 1 than in class 2 and the predominant uses of water require a higher degree of water purity. The biological index based on diatoms was the most restrictive index whose water classes and categorizations have shown an ecological status that could threaten the protection of aquatic communities on the Curuai floodplain. We suggest the combined use of both indices-physicochemical and biological for water quality assessment in this type of environment.

Multimethodology applied to the evaluation of Healthcare in Brazilian municipalities.

The integration of quantitative indicators with qualitative descriptions of context is a noticeable demand from many different scientific disciplines, since it contributes to linking theoretical and practical approaches to problem solving. Amongst them are the problem structuring methods, systems thinking and multimethodology. This work presents a mixed quantitative and qualitative methodological approach to aid formulation and structuring of performance measurement of health care in 5565 Brazilian municipalities. Data mining and data envelopment analysis (DEA) are applied in the context of conceptual mapping, thus shedding light on both quantitative and qualitative factors that influence health performance. Our aim is to propose a methodology for performance indicators to support health care policy making in Brazil, using quantitative indicators. However, the approach does not lose track of the role of important qualitative factors in the attribution of meaning to performance assessments. The methodological and analytical results can strengthen mutual understanding by analysts and stakeholders of the problem at hand. Quantitative results allow inefficient municipalities to understand the causes of their overall efficiency in terms of particular low partial DEA efficiencies combined with high deathrates.

Planning and understanding the intensive care network in the State of Rio de Janeiro (RJ), Brazil: a complex societal problem. / Planejamento e compreensão da rede de terapia intensiva no Estado do Rio de Janeiro: um problema social complexo.

OBJECTIVES: To determine the optimal number of adult intensive care unit beds to reduce patient's queue waiting time and to propose policy strategies. METHODS: Multimethodological approach: (a) quantitative time series and queueing theory were used to predict the demand and estimate intensive care unit beds in different scenarios; (b) qualitative focus group and content analysis were used to explore physicians' attitudes and provide insights into their behaviors and belief-driven healthcare delivery changes. RESULTS: A total of 33,101 requests for 268 regulated intensive care unit beds in one year resulted in 25% admissions, 55% queue abandonment and 20% deaths. Maintaining current intensive care unit arrival and exit rates, there would need 628 beds to ensure a maximum wait time of six hours. A reduction of the current abandonment rates due to clinical improvement or the average intensive care unit length of stay would decrease the number of beds to 471 and 366, respectively. If both were reduced, the number would reach 275 beds. The interviews generated 3 main themes: (1) the doctor's conflict: fair, legal, ethical and shared priorities in the decision-making process; (2) a failure of access: invisible queues and a lack of infrastructure; and (3) societal drama: deterioration of public policies and health care networks. CONCLUSION: The queue should be treated as a complex societal problem with a multifactorial origin requiring integrated solutions. Improving intensive care unit protocols and reengineering the general wards may decrease the length of stay. It is essential to redefine and consolidate the regulatory centers to organize the queue and provide available resources in a timely manner, by using priority criteria, working with stakeholders to guarantee clinical governance and network organization.

OBJETIVO: Determinar o número de leitos de UTI para pacientes adultos a fim de reduzir o tempo de espera na fila e propor políticas estratégicas. MÉTODOS: Abordagem multimetodológica: (a) quantitativa, através de séries temporais e teoria de filas, para prever a demanda e estimar o número de leitos de terapia intensiva em diferentes cenários; (b) qualitativa, através do grupo focal e análise do conteúdo, para explorar o comportamento, atitudes e as crenças dos médicos nas mudanças da saúde. RESULTADOS: As 33.101 solicitações de internação nos 268 leitos regulados de terapia intensiva, durante 1 ano, resultaram na admissão de 25% dos pacientes, 55% abandonos da fila e 20% de óbitos. Mantidas as taxas atuais de entrada e saída da unidade de terapia intensiva, seriam necessários 628 leitos para assegurar que o tempo máximo de espera fosse de 6 horas. A redução das atuais taxas de abandono, em razão de melhora clínica ou a redução do tempo médio de permanência na unidade, diminuiria o número de leitos necessários para 471 e para 366, respectivamente. Caso se conseguissem ambos os objetivos, o número chegaria a 275 leitos. As entrevistas geraram três temas principais: o conflito do médico: a necessidade de estabelecer prioridades justas, legais, éticas e compartilhadas na tomada de decisão; o fracasso no acesso: filas invisíveis e falta de infraestrutura; o drama social: deterioração das políticas públicas e desarticulação das redes de saúde. CONCLUSÃO: A fila deve ser tratada como um problema social complexo, de origem multifatorial e que requer soluções integradas. Redimensionar o número de leitos não é a única solução. Melhorar os protocolos e prover a reengenharia das enfermarias gerais podem reduzir o tempo de permanência na unidade. É essencial consolidar as centrais de regulação para organizar a fila e fornecer os recursos disponíveis em tempo adequado, usando critérios de prioridade e trabalhando em conjunto com as pessoas envolvidas para garantir a governança clínica e a organização da rede.

The interviews generated 3 main themes: (1) the doctor's conflict: fair, legal, ethical and shared priorities in the decision-making process; (2) a failure of access: invisible queues and a lack of infrastructure; and (3) societal drama: deterioration of public policies and health care networks. Conclusion: The queue should be treated as a complex societal problem with a multifactorial origin requiring integrated solutions. Improving intensive care unit protocols and reengineering the general wards may decrease the length of stay. It is essential to redefine and consolidate the regulatory centers to organize the queue and provide available resources in a timely manner, by using priority criteria, working with stakeholders to guarantee clinical governance and network organization.

Difficulties in access and estimates of public beds in intensive care units in the state of Rio de Janeiro.

OBJECTIVE: To estimate the required number of public beds for adults in intensive care units in the state of Rio de Janeiro to meet the existing demand and compare results with recommendations by the Brazilian Ministry of Health. METHODS: The study uses a hybrid model combining time series and queuing theory to predict the demand and estimate the number of required beds. Four patient flow scenarios were considered according to bed requests, percentage of abandonments and average length of stay in intensive care unit beds. The results were plotted against Ministry of Health parameters. Data were obtained from the State Regulation Center from 2010 to 2011. RESULTS: There were 33,101 medical requests for 268 regulated intensive care unit beds in Rio de Janeiro. With an average length of stay in regulated ICUs of 11.3 days, there would be a need for 595 active beds to ensure system stability and 628 beds to ensure a maximum waiting time of six hours. Deducting current abandonment rates due to clinical improvement (25.8%), these figures fall to 441 and 417. With an average length of stay of 6.5 days, the number of required beds would be 342 and 366, respectively; deducting abandonment rates, 254 and 275. The Brazilian Ministry of Health establishes a parameter of 118 to 353 beds. Although the number of regulated beds is within the recommended range, an increase in beds of 122.0% is required to guarantee system stability and of 134.0% for a maximum waiting time of six hours. CONCLUSIONS: Adequate bed estimation must consider reasons for limited timely access and patient flow management in a scenario that associates prioritization of requests with the lowest average length of stay.

Dynamic network data envelopment analysis for university hospitals evaluation.

OBJECTIVE: To develop an assessment tool to evaluate the efficiency of federal university general hospitals. METHODS: Data envelopment analysis, a linear programming technique, creates a best practice frontier by comparing observed production given the amount of resources used. The model is output-oriented and considers variable returns to scale. Network data envelopment analysis considers link variables belonging to more than one dimension (in the model, medical residents, adjusted admissions, and research projects). Dynamic network data envelopment analysis uses carry-over variables (in the model, financing budget) to analyze frontier shift in subsequent years. Data were gathered from the information system of the Brazilian Ministry of Education (MEC), 2010-2013. RESULTS: The mean scores for health care, teaching and research over the period were 58.0%, 86.0%, and 61.0%, respectively. In 2012, the best performance year, for all units to reach the frontier it would be necessary to have a mean increase of 65.0% in outpatient visits; 34.0% in admissions; 12.0% in undergraduate students; 13.0% in multi-professional residents; 48.0% in graduate students; 7.0% in research projects; besides a decrease of 9.0% in medical residents. In the same year, an increase of 0.9% in financing budget would be necessary to improve the care output frontier. In the dynamic evaluation, there was progress in teaching efficiency, oscillation in medical care and no variation in research. CONCLUSIONS: The proposed model generates public health planning and programming parameters by estimating efficiency scores and making projections to reach the best practice frontier.

RESUMO OBJETIVO Determinar o número necessário de leitos públicos de unidades de terapia intensiva para adultos no estado do Rio de Janeiro para atender à demanda existente, e comparar os resultados com a recomendação do Ministério da Saúde. MÉTODOS Seguiu-se modelo híbrido que agrega séries temporais e teoria de filas para prever a demanda e estimar o número de leitos necessários. Foram considerados quatro cenários de fluxo de pacientes, de acordo com as solicitações de vagas, proporção de desistências e tempo médio de permanência no leito de unidade de terapia intensiva. Os resultados foram confrontados com os parâmetros do Ministério da Saúde. Os dados foram obtidos da Central Estadual de Regulação, de 2010 a 2011. RESULTADOS Houve 33.101 solicitações médicas para 268 leitos de unidade de terapia intensiva regulados no Rio de Janeiro. Com tempo médio de permanência das unidades de terapia intensiva reguladas de 11,3 dias, haveria necessidade de 595 leitos ativos para garantir a estabilidade do sistema e 628 leitos para o tempo máximo na fila de seis horas. Deduzidas as atuais taxas de desistência por melhora clínica (25,8%), estes números caem para 441 e 471. Com tempo médio de permanência de 6,5 dias, o número necessário seria de 342 e 366 leitos, respectivamente; deduzidas as taxas de desistência, de 254 e 275. O Ministério da Saúde estabelece parâmetro de 118 a 353 leitos. Embora o número de leitos regulados esteja na faixa recomendada, necessita-se incremento de 122,0% de leitos para garantir a estabilidade do sistema e de 134,0% para um tempo máximo de espera de seis horas. CONCLUSÕES O dimensionamento adequado de leitos deve considerar os motivos de limitações de acesso oportuno e a gestão do fluxo de pacientes em um cenário que associa priorização das solicitações com menor tempo médio de permanência.

RESUMO OBJETIVO Desenvolver ferramenta de avaliação de eficiência de hospitais universitários federais de perfil geral. MÉTODOS A análise envoltória de dados, técnica de programação linear, constrói uma fronteira de melhores práticas pela comparação da produção observada dadas as quantidades de recursos despendidas. O modelo é orientado a produto, e considera retornos variáveis de escala. A análise envoltória de dados em redes considera variáveis de ligação que pertencem a mais de uma dimensão (no modelo, médicos residentes, internações ajustadas e projetos de pesquisa). A análise envoltória de dados dinâmica usa variáveis de transporte (no modelo, receita) para analisar o deslocamento da fronteira em anos subsequentes. Os dados foram coletados do sistema de informações do MEC, 2010 a 2013. RESULTADOS Os escores médios de assistência, ensino e pesquisa no período foram: 58,0%, 86,0% e 61,0%, respectivamente. Em 2012, ano de melhor desempenho, para que todas as unidades atingissem a fronteira, seria necessário aumento médio de consultas de 65,0%; de internações, de 34,0%; de alunado de graduação, de 12,0%, de residência multiprofissional, de 13,0%, de pós-graduação, de 48,0%; de projetos de pesquisa, de 7,0%; além de queda de 9,0% de residentes médicos. No mesmo ano, para melhora da fronteira de produção assistencial, seria necessária a injeção de um aporte adicional de receita de 0,9%. Observou-se progressão da eficiência no ensino; oscilação na assistência e estagnação na pesquisa na avaliação dinâmica. CONCLUSÕES O modelo proposto gera parâmetros de planejamento e programação em saúde pública por meio do cálculo dos escores de eficiência e das projeções necessárias para alcance das fronteiras de melhores práticas.
