Análise dos custos diretos e indiretos da COVID-19 em um hospital brasileiro / Analysis of the direct and indirect costs of COVID-19 in a Brazilian hospital

Objetivo: Avaliar os custos diretos na perspectiva hospitalar e do Sistema Único de Saúde (SUS), bem como os custos indiretos de pacientes hospitalizados por COVID-19. Métodos: Estudo observacional com coleta de dados por micro e macrocusteio, realizado com pacientes admitidos por COVID-19 em um hospital paulista (março a setembro de 2020). Custos indiretos foram obtidos pelos métodos de capital humano e de anos de vida ajustados pela incapacidade (DALY). Análises de Mann-Whitney e regressão linear foram realizadas. Resultados: Foram incluídos 158 indivíduos com mediana de idade de 57 anos (IIQ 42-68 anos). A mediana de custo da internação na perspectiva do SUS e hospitalar foi de, respectivamente, R$ 2.009,46 (IIQ: R$ 1.649,11; R$ 4.847,36), principalmente devido à unidade de terapia intensiva (UTI), e R$ 19.055,91 (IIQ: R$ 8.399,47; R$ 38.438,00), principalmente devido a recursos humanos. Tempo total de internação (p < 0,001), óbito (p < 0,001) e ventilação invasiva (p < 0,001) foram preditores de aumento de custo. Foi identificada perda de 381,5 DALY e perda de produtividade de 128 anos, equivalente a US$ 855.307. Conclusão: Os principais direcionadores de custo foram recursos humanos e UTI. Entretanto, na perspectiva da sociedade, foi identificado o maior impacto devido à perda de produtividade e DALY. Tempo de hospitalização foi um dos grandes contribuidores do custo, e esse fator pode estar atrelado a gravidade da doença e protocolos de cuidado ao paciente.

Objective: To evaluate the direct costs from the hospital and Unified Health System (SUS) perspective, as well as the indirect costs of patients hospitalized by COVID-19. Methods: Observational study with data collection by micro- and macro-costing, carried out with patients hospitalized in a hospital in São Paulo (March-September 2020). Indirect costs were obtained using human capital and disability-adjusted life years (DALY) methods. Mann-Whitney and linear regression analyzes were performed. Results: 158 individuals were included, with a median age of 57 years (IQR 42-68 years). The median cost of admission in the SUS and hospital perspective was, respectively, R$ 2,009.46 (IQR: R$ 1,649.11; R$ 4,847.36), mainly due to the intensive care unit (ICU) and R$ 19,055.91 (IQR: R$ 8,399.47; R$ 38,438.00), mainly due to human resources. The total length of stay in hospital (p < 0.001), death (p < 0.001) and invasive ventilation (p < 0.001) were predictors of cost increase.

Impacto de intervenção educativa sobre segurança do paciente no conhecimento e atitude de estudantes de medicina / Impact of educational intervention about patient safety on the knowledge and attitudes of medical students

Introdução: a segurança é considerada um pilar da qualidade dos cuidados à saúde e seu sucesso depende do comprometimento individual e coletivo, porém, seu ensino é incipiente nas faculdades de medicina brasileiras. Objetivo: avaliar o impacto de intervenção sobre segurança do paciente no conhecimento e atitude dos alunos de medicina. Metodologia: conduziu-se o estudo do tipo pré-pós intervenção de janeiro a novembro de 2017. Todos os estudantes de graduação de medicina do 6° ano que realizaram estágio no hospital sob estudo foram incluídos. A intervenção compreendeu acolhimento, aula expositiva, estágio e aplicação de questionário para avaliar conhecimento e atitude sobre erro humano e segurança do paciente, que foi aplicado em 3 momentos: antes da aula e do estágio, imediatamente após a aula e após 15 dias da aula e término do estágio. As notificações de incidentes foram analisadas. Resultados: participaram 98 (100%) estudantes, dos quais 62% eram do sexo masculino, com média de idade de 25,8 anos. Após a intervenção, observou-se melhora significativa no conhecimento sobre a inevitabilidade do erro em saúde e a caracterização do profissional envolvido no incidente. As atitudes autorreferidas melhoraram significativamente em relação à necessidade de apoio institucional, abordagem sistêmica e adoção de práticas seguras para prevenção de erros; comunicação sobre riscos e erros para superiores, paciente e familiares e que apenas os médicos podem analisar os incidentes. Conclusão: a intervenção foi efetiva para aumentar o conhecimento dos estudantes sobre cultura de segurança, porém limitou-se na mudança de atitude, pois não evidenciou a notificação de incidentes em saúde.

Background: safety is considered a pillar of the quality of health care and its success depends on individual and collective commitment. However, in Brazilian medical schools there are fewer approaches to teaching this subject. Objective: To evaluate the impact of educational intervention about patient safety on the knowledge and attitude of medical students. Methodology: a pre-post intervention study was conducted from January to November 2017. All 6th year medical students who underwent an internship at the hospital under study were included. The intervention comprised reception, lecture, internship and application of a questionnaire to assess knowledge and attitude about human error and patient safety, which was applied in 3 moments: before class and internship, immediately after class and before of internship and in the end of the internship. Adverse drug reports were assessed. Results: 98 (100%) students participated, of which 62% were male, with an average age of 25.8 years. After intervention, there was a significant improvement in knowledge about the inevitability of health errors and the characterization of the professional involved in the incident. Self-reported attitudes have significantly improved in relation to the need for institutional support, a systemic approach and the adoption of safe practices to prevent errors; communication about risks and errors to superiors, patient and family and that only doctors can analyze the incidents. Conclusion: the intervention was effective in increasing students' knowledge of safety culture, but was limited to changing attitudes, as it did not show the notification of health incidents.

Serum potassium level used as trigger doubled the detection of adverse drug events when compared with calcium polystyrene sulfonate trigger: a cross-sectional study

Background: Prescription of calcium polystyrene sulfonate (CPS) has been considered a trigger with good performance to detect hyperkalemia related to adverse drug events (ADE). However, CPS prescription may underestimate the rate of ADE. Objective: To compare the performance of the serum potassium level (SPL) >5.0mEq/L and CPS triggers in detecting hyperkalemia related to ADE. Design and setting: A six-month cross-sectional study was conducted in a Brazilian medium-complexity public hospital. Methods: SPL Tests with results >5.0mEq/L and the prescriptions of CPS of all patients hospitalized in the internal medicine and infectious diseases wards were used as trigger tools to detect potential ADE. Primary outcome: patients with hyperkalemia related to ADE. Secondary outcomes: effectiveness of treatments and ADE. Variables analyzed were SPL tests, CPS prescriptions, treatments of hyperkalemia and comorbidities. Positive predictive values (PPV) of CPS and SPL triggers were calculated and compared. Results: In total 2,466 SPL tests were assessed, of which 513 were triggered (>5.0mEq/L). The tests triggered 198 patients with hyperkalemia, of whom 121 had hyperkalemia related to ADE (PPV=0.61). In total, 101 CPS prescriptions triggered tests in 35 patients with hyperkalemia, among whom 21 cases were related to ADE (PPV=0.60). SPL detected 204 ADE (PPV=0.40), while CPS prescription detected 22 (PPV=0.21). Seven pharmacological and four non-pharmacological treatments were identified. CPS showed the lowest effectiveness (PPV=0.71). Conclusion: SPL>5.0mEq/L increased the detection of ADE by 9.3-fold, the number of patients tracked with hyperkalemia related to ADE by 5.8-fold, and doubled the performance in detection of ADE in comparison with the prescription of the CPS trigger.

Impacto da gestão do consumo de água no Hospital Estadual Américo Brasiliense: um estudo piloto / Impact of water consumption management at the Brazilian American state hospital: a pilot study

Objetivos: Avaliar a redução da extração de água no poço artesiano após a instalação de medidores de vazão em pontos de distribuição hídrica num hospital. Métodos: Conduziu-se estudo piloto de intervenção do tipo antes e depois no Hospital Estadual Américo Brasiliense, localizado no interior do estado de São Paulo. A gestão da água iniciou-se em 2010 e realizou-se por meio do monitoramento de sete hidrômetros pré-equipados para sistema de telemetria, com relojoaria mecânica e sistema de turbinas, dos quais quatro foram instalados em 2016. Em março de 2017, foram instalados chuveiros e torneiras para limpeza com redutores de vazão em todo o hospital e arejadores em todas as torneiras para higienização das mãos. Analisou-se o impacto dos acessórios comparando-se a captação de água (m3) do poço artesiano. Estimou-se o retorno financeiro após a implantação das medidas. Resultados: Observou-se redução entre 21% e 42% (600 e 1.444 m³) do total do consumo hídrico e em 8.000 m3 de água por ano na extração do aquífero. Com a economia entre 800 e 1.000 m3 /mês de água, obteve-se retorno dos investimentos em 13 dias da implantação dos acessórios, pois o montante investido para compra e instalação dos equipamentos foi de 10.955 mil reais e a economia advinda da redução do consumo hídrico foi de 24.302 mil reais. Conclusão: A instalação de medidores de vazão é custo-efetiva para economia de água e financeira em hospitais. As melhorias contribuem para aumentar a credibilidade do desenvolvimento de projetos sustentáveis e a viabilidade de investimentos em ações ambientais

Objectives: Assess the reduction of water extraction in the artesian well after installation of flow restrictors in points of hydric distribution in a hospital. Methods: A pilot pre-post interventional study was carried out in Américo Brasiliense Hospital State, localized in the province of São Paulo (Brazil). Water management began in 2010. The monitoring was performed with seven water flow meters with telemetry system, with watchmaking and turbines of which four were installed in 2016. March 2017, flow restrictors on cleaning sinks and showers were installed, as well as aerators for hand basins. The impact of accessories was assessed comparing the water capitation (m3) in artesian well before and after interventions. Financial payback was estimated after implementation of the accessories. Results: Total hydric consumption decrease by 21% a 42% (600 a 1,444 m³) and reduced the extraction of aquifer in 8,000 m3 of water/year. With the aid of approximately 1,000 m3/month of water economy, the hospital had payback thirteen days after the implementation of the accessories, since the valor invested buy and install of the equipment was R$ 10.955,00 reais and the save regarding the decrease of hydric consume was R$ 24.302,00 reais. Conclusion: Flow restrictors installation in critical points of hydric distribution is cost-effective to reduce water consumption and costs in hospitals. Improvements performed contribute to raise the credibility of sustainability projects and the viability of investment in environmental actions.

Assessment of the adherence to and costs of the prophylaxis protocol for venous thromboembolism

OBJECTIVES: Evaluate adherence to the therapeutic prophylaxis protocol for venous thromboembolism (VTE) as well as the costs of this practice. METHODS: A descriptive and cross-sectional study was conducted at a State General Hospital in Brazil through reports of drug dispensions, prescriptions and risk stratification of patients. Adherence to the VTE prophylaxis protocol was monitored. The tests for VTE diagnosis measured the adherence to therapeutic prophylaxis treatment, and the purchase prices of the drugs went into the calculation of drug therapy costs. The level of adherence to prescriptions for VTE prophylaxis in the hospital was classified as "adherence", "non-adherence" and "justified non-adherence" when compared with the protocol. RESULTS: Protocol adherence was observed for 50 (30.9%) patients, and non-adherence was observed for 63 (38.9%) patients, generating an additional cost of $180.40/month. Justified non-adherence in 49 (30.2%) patients generated $514.71/month in savings due to a reduction in the number of daily administrations of unfractionated heparin while still providing an effective method for preventing VTE. Twenty-six patients stratified as having medium to high risk of VTE who did not receive prophylaxis were identified, generating $154.41 in savings. However, these data should be evaluated with caution since the risks and outcomes associated with not preventing VTE outweigh the economy achieved from not prescribing a drug when a patient needs it. The only case of VTE identified during the study period was related to justified non-adherence to the protocol. CONCLUSION: The protocol is based on scientific evidence that describes an effective therapy to prevent VTE. However, the protocol should be updated because the justifications for non-adherence are based on scientific evidence, and this justified non-adherence generates savings and yields effective disease prevention.

The cardiopulmonary bypass and cancer dissemination puzzle

Abstract Early cancer diagnosis, new therapies that increased survival of patients, besides the increasingly elderly population are some factors would be associated with possible cancer dissemination in patients under cardiopulmonary bypass (CPB) cardiac surgery. Also, the benefits, and risks, regarding long-term survival, have not yet been established. Therefore, cardiac surgery morbimortality may be superior in patients with cancer disease. Also, immunologic and inflammatory changes secondary to CPB can also increase tumor recurrence. After a brief introduction and CPB immunologic the two main topic subjects included: 1) Combined heart surgery and lung resection and; 2) Possible influence of neoplasia type. After observing the relative literature scarcity, we keep the opinion that "CPB has a modest association with cancer progression" and that "CPB and cancer dissemination should be a logical but unlikely association."

Incidents reporting: barriers and strategies to promote safety culture / Notificação de incidentes: barreiras e estratégias para promover a cultura de segurança / Notificación de incidentes: barreras y estrategias para promover la cultura de seguridad

ABSTRACT Objective The purpose was to identify the barriers of underreporting, the factors that promote motivation of health professionals to report, and strategies to enhance incidents reporting. Method Group conversations were carried out within a hospital multidisciplinary team. A mediator stimulated reflection among the subjects about the theme. Sixty-five health professionals were enrolled. Results Complacency and ambition were barriers exceeded. Lack of responsibility about culture of reporting was the new barrier observed. There is a belief only nurses should report incidents. The strategies related to motivation reported were: feedback; educational intervention with hospital staff; and simplified tools for reporting (electronic or manual), which allow filling critical information and traceability of management risk team to improve the quality of report. Conclusion Ordinary and practical strategies should be developed to optimize incidents reporting, to make people aware about their responsibilities about the culture of reporting and to improve the risk communication and the quality of healthcare and patient safety.

Presentation of an experimental method to induce in vitro ("organ chambers") respiratory acidosis and its effect on vascular reactivity

PURPOSE: To create in vitro a model to generate acidosis by CO2 bubbling "organ chambers", which would be useful for researchers that aim to study the effects of acid-base disturbs on the endothelium-dependent vascular reactivity. METHODS: Eighteen male Wistar rats (230-280g) were housed, before the experiments, under standard laboratory conditions (12h light/dark cycle at 21°C), with free access to food and water. The protocol for promoting in vitro respiratory acidosis was carried out by bubbling increased concentrations of CO2. The target was to achieve an ideal way to decrease the pH gradually to a value of approximately 6.6.It was used, initially, a gas blender varying concentrations of the carbogenic mixture (95% O2 + 5% CO2) and pure CO2. RESULTS: 1) 100% CO2, pH variation very fast, pH minimum 6.0; 2) 90%CO2 pH variation bit slower, pH minimum6.31; 3) 70%CO2, pH variation slower, pH minimum 6.32; 4) 50% CO2, pH variation slower, pH minimum 6:42; 5) 40 %CO2, Adequate record, pH minimum 6.61, and; 6) 30 %CO2 could not reach values below pH minimum 7.03. Based on these data the gas mixture (O2 60% + CO2 40%) was adopted, CONCLUSION: This gas mixture (O2 60% + CO2 40%) was effective in inducing respiratory acidosis at a speed that made, possible the recording of isometric force. .

Does rosmarinic acid underestimate as an experimental cardiovascular drug? / Seria o ácido rosmarínico subestimado como droga cardiovascular experimental?

PURPOSE: The rationale of the present review is to analize the activity of Rosmarinus officinalis in the the cardiovascular system METHODS: A MEDLINE database search (from January 1970 to December 2011) using only rosmarinic acid as searched term. RESULTS: The references search revealed 509 references about rosmarinic acid in 40 years (the first reference is from 1970). There is a powerful prevalence of antioxidant and cancer studies. Other diseases are few cited, as inflammation, brain (Alzheimer and Parkinson disease) and, memory; allergy; diabetes; atherosclerosis, and; hypertension. It is necessary to consider the complete absence of studies on coronary artery disease, myocardial ischemia, heart failure or ischemia/reperfusion injury. CONCLUSION: Rosmarinic acid is underestimated as an experimental cardiovascular drug and deserves more attention.

OBJETIVO: A justificativa da revisão é analisar a atividade de Rosmarinus officinalis no sistema cardiovascular MÉTODOS: Uma busca de banco de dados MEDLINE (de janeiro de 1970 a dezembro de 2011), utilizando apenas o ácido rosmarínico como termo pesquisado. RESULTADOS: A busca referências revelou 509 referências sobre o ácido rosmarínico em 40 anos (a primeira referência é de 1970). Há uma prevalência poderoso antioxidante e estudos do câncer. Outras doenças são citados alguns, como o cérebro, inflamação (de Alzheimer e doença de Parkinson) e, a memória, hipertensão, alergia, diabetes, aterosclerose, e. É necessário ter em conta a ausência completa de estudos sobre a doença de artéria coronária, isquemia do miocárdio, insuficiência cardíaca ou isquemia / lesão de reperfusão. CONCLUSÃO: O ácido rosmarínico é subestimado como uma droga experimental cardiovascular e merece mais atenção.

Laringoscopia de suspensão para o cirurgião torácico: quando e como utilizá-la / Suspension laryngoscopy for the thoracic surgeon: when and how to use it

A laringoscopia de suspensão é um dos procedimentos mais comumente utilizados em otorrinolaringologia para a abordagem diagnóstica e cirúrgica da laringe mas é pouco conhecida e utilizada pelo cirurgião torácico. As indicações para sua utilização são similares às da broncoscopia rígida (dilatações, aplicação de próteses endotraqueais e ressecções tumorais), podendo ser realizada em crianças e adultos. Constitui-se em uma alternativa eficaz, mormente na indisponibilidade de equipamento de traqueobroncoscopia rígida, sendo, portanto, uma alternativa viável em centros menores. Nesta comunicação, descrevemos a técnica e suas aplicações na cirurgia torácica.

Suspension laryngoscopy is one of the most common otolaryngological procedures for the diagnosis and surgical approach to the larynx. However, most thoracic surgeons are not familiar with the procedure and seldom use it. The indications for its use are similar to those for that of rigid bronchoscopy (dilatation, endoprosthesis insertion, and tumor resection). It can be performed in children and adults. Suspension laryngoscopy is an alternative when rigid bronchoscopy is unavailable and is therefore a viable option for use at smaller facilities. In this communication, we describe the technique and the applications of suspension laryngoscopy in thoracic surgery.
