Impact of the COVID-19 pandemic on the mental health of frontline healthcare workers in a highly affected region in Brazil.

BACKGROUND: The COVID-19 pandemic had a major impact on the mental health of healthcare workers (HCWs), especially in low and middle-income countries, which had to face additional political, social, and economic challenges. We thus aimed to assess the prevalence of mental health outcomes and the associated factors in HCWs treating COVID-19 patients in one of the most affected regions in Brazil. METHODS: We used the Respondent-Driven Sampling method to assess the risks of COVID-19 infection and symptoms of mental disorders in nurses, nursing technicians, and physicians who worked on the frontline in the metropolitan region of Recife. 865 healthcare workers completed a survey regarding sociodemographic data, work-related risks, and symptoms of mental disorders - SRQ-20 for common mental disorders (CMD); AUDIT-C for problematic alcohol use; GAD-7 for anxiety; PHQ-9 for depression; PCL-5 for post-traumatic stress disorder (PTSD). Gile's successive sampling estimator was used to produce the weighted estimates by professional category. A Poisson regression model with robust variance was used to analyze factors associated with a positive screening for CMD. We will present the results of a cross-sectional analysis of the mental health outcomes after the first peak of COVID-19 - from August 2020 to February 2021. RESULTS: The prevalence ratios for a positive screening for CMD were 34.9% (95% CI: 27.8-41.9) in nurses, 28.6% (95% CI: 21.3-36.0) in physicians, and 26.6% (95% CI: 16.8-36.5) in nursing technicians. Nurses presented a higher prevalence of depressive symptoms (23%). Positive screening for problematic alcohol use (10.5 to14.0%), anxiety (10.4 to 13.3%), and PTSD (3.3 to 4.4%) were similar between the professional categories. The main factors associated with CMD in nurses and physicians were related to an intrinsic susceptibility to mental illness, such as previous or family history of psychiatric disorder, and female sex. Among nurse technicians, work-related factors, such as accidents with biological material, presented the strongest association with CMD. CONCLUSION: The mental health of HCWs fighting COVID-19 in Recife was severely affected. It is crucial that healthcare services provide adequate working conditions and psychological support, investing in programs to promote and protect HCWs mental health.

Reports from the frontline: health workers describe COVID-19 risks and fears in five cities in Brazil.

BACKGROUND: Health providers are under unprecedented pressures to perform in the COVID-19 health crisis and under unprecedented risks. We initiated a large mixed-method survey of health professionals in five large metropolitan areas in Brazil to document the risks and needs of health professionals. To initiate the study, we conducted formative research. METHODS: We conducted 77 open-ended semi-structured interviews online in a convenience sample of physicians, nurses, nurse technicians, and physiotherapists in Belem, Fortaleza, Porto Alegre, Recife, and São Paulo, Brazil. Design, data collection, and analysis were informed by Rapid Ethnographic Analysis (REA). RESULTS: Responses are organized into three themes that emerged in the interviews: the lack of preparation - both locally and nationally-for the pandemic and its effects on staffing and training; the overlap of personal, family, and professional risk and consequences; and inadequately addressed anxiety and suffering among health staff. CONCLUSIONS: Our respondents were unprepared for the epidemic, especially the institutional sequelae and psychological cost. These consequences were exacerbated by both lack of leadership and sweeping changes undercutting the Brazilian health system noted by almost all participants.

Ketamine study: Protocol for naturalistic prospective multicenter study on subcutaneous ketamine infusion in depressed patients with active suicidal ideation.

Background: Psychiatric disorders are associated with more than 90% of reported suicide attempts worldwide, but few treatments have demonstrated a direct effect in reducing suicide risk. Ketamine, originally an anesthetic, has been shown anti-suicide effects in clinical trials designed to treat depression. However, changes at the biochemical level were assessed only in protocols of ketamine with very limited sample sizes, particularly when the subcutaneous route was considered. In addition, the inflammatory changes associated with ketamine effects and their correlation with response to treatment, dose-effect, and suicide risk warrant further investigation. Therefore, we aimed to assess whether ketamine results in better control of suicidal ideation and/or behavior in patients with depressive episodes and whether ketamine affects psychopathology and inflammatory biomarkers. Materials and methods: We report here the design of a naturalistic prospective multicenter study protocol of ketamine in depressive episodes carried out at Hospital de Clínicas de Porto Alegre (HCPA) and Hospital Moinhos de Vento (HMV). The study was planned to recruit adult patients with Major depressive disorder (MDD) or Bipolar disorder (BD) types 1 or 2, who are currently in a depressive episode and show symptoms of suicidal ideation and/or behavior according to the Columbia-Suicide Severity Rating Scale (C-SSRS) and have been prescribed ketamine by their assistant psychiatrist. Patients receive ketamine subcutaneously (SC) twice a week for 1 month, but the frequency can be changed or the dose decreased according to the assistant physician's decision. After the last ketamine session, patients are followed-up via telephone once a month for up to 6 months. The data will be analyzed using repeated measures statistics to evaluate the reduction in suicide risk as a primary outcome, as per C-SSRS. Discussion: We discuss the need for studies with longer follow-ups designed to measure a direct impact on suicide risk and that additional information about the safety and tolerability of ketamine in particular subset of patients such as those with depression and ideation suicide. In line, the mechanism behind the immunomodulatory effects of ketamine is still poorly understood. Trial registration: https://clinicaltrials.gov/, identifier NCT05249309.

Risk of SARS-CoV-2 infection among front-line healthcare workers in Northeast Brazil: a respondent-driven sampling approach.

OBJECTIVES: We assessed the prevalence of SARS-CoV-2 infection, personal protective equipment (PPE) shortages and occurrence of biological accidents among front-line healthcare workers (HCW). DESIGN, SETTING AND PARTICIPANTS: Using respondent-driven sampling, the study recruited distinct categories of HCW attending suspected or confirmed patients with COVID-19 from May 2020 to February 2021, in the Recife metropolitan area, Northeast Brazil. OUTCOME MEASURES: The criterion to assess SARS-CoV-2 infection among HCW was a positive self-reported PCR test. RESULTS: We analysed 1525 HCW: 527 physicians, 471 registered nurses, 263 nursing assistants and 264 physical therapists. Women predominated in all categories (81.1%; 95% CI: 77.8% to 84.1%). Nurses were older with more comorbidities (hypertension and overweight/obesity) than the other staff. The overall prevalence of SARS-CoV-2 infection was 61.8% (95% CI: 55.7% to 67.5%) after adjustment for the cluster random effect, weighted by network, and the reference population size. Risk factors for a positive RT-PCR test were being a nursing assistant (OR adjusted: 2.56; 95% CI: 1.42 to 4.61), not always using all recommended PPE while assisting patients with COVID-19 (OR adj: 2.15; 95% CI: 1.02 to 4.53) and reporting a splash of biological fluid/respiratory secretion in the eyes (OR adj: 3.37; 95% CI: 1.10 to 10.34). CONCLUSIONS: This study shows the high frequency of SARS-CoV2 infection among HCW presumably due to workplace exposures. In our setting, nursing assistant comprised the most vulnerable category. Our findings highlight the need for improving healthcare facility environments, specific training and supervision to cope with public health emergencies.

Time-driven activity-based costing as a strategy to increase efficiency: An analyses of interventional coronary procedures.

Monitoring the costs is one of the key components underlying value-based health care. This study aimed to evaluate the cost-saving opportunities of interventional coronary procedures (ICPs). Data from 90 patients submitted to elective ICP were evaluated in five Brazilian hospitals. Time-driven activity-based costing, that guides the cost estimates using the time consumed and the capacity cost rates per resource as the data input, was used to assess costs and the time spent over the care pathway. Descriptive cost analyses were followed by a labour cost-saving estimate potentially achieved by the redesign of the ICP pathway. The mean cost per patient varied from $807 to $2639. The length of the procedure phase per patient was similar among the hospitals, while the post-procedure phase presented the highest variation in length. The highest direct cost saving opportunities are concentrated in the procedure phase. By comparing the benchmark service with the most expensive one, it was estimated that redesigning physician practices could decrease 51% of the procedure cost. This application is pioneered in Brazil and demonstrates how detailed cost information can contribute to driving health care management to value by identifying cost-saving opportunities.

The use of micro-costing in an economic analysis of allogeneic HSCT in Brazil / O uso do microcusteio na análise econômica do TCTH alogênico no Brasil

Objetivo: O objetivo deste estudo foi estimar os custos do tratamento do transplante de células--tronco hematopoéticas (TCTH) em um centro de referência no Brasil. Métodos: A população do estudo foi composta por pacientes provenientes da lista de TCTH do Sistema Único de Saúde submetidos ao TCTH em um hospital do sul do Brasil, entre 2016 e 2019. A avaliação de custos foi realizada por meio de um estudo de microcusteio, baseado no Time-Driven Activity-based Costing (TDABC) adaptado para estudos econômicos em saúde e incluiu as seguintes etapas: definição da questão de pesquisa, coleta de dados estruturada e análise estatística dos resultados. Resultados: O custo total do TCTH foi de $ 155.110 ($ 92.794 ­ $ 249.146 USD). O TCTH de doador não aparentado compatível foi mais caro do que o TCTH de doador aparentado compatível. Os principais fatores de custo envolvem complicações pós-transplante, principalmente a ocorrência de infecções. Em relação à composição dos custos, exames e procedimentos representam o maior custo em TCTH (45%). Conclusão: Essas estimativas podem ser aplicáveis a novas avaliações de custo-efetividade do TCTH e ajudar os gestores na tomada de decisão em saúde, especialmente em países de média renda

Objective: The objective of this study was to estimate treatment costs of Hematopoietic stem cell transplantation (HSCT) at a reference center in Brazil. Methods: The study population consisted of patients from the Unified Health System HSCT who underwent HSCT in southern Brazil between 2016 and 2019. Costs were measured using a micro-costing approach, based on Time-Driven Activity-based Costing (TDABC) adapted for economic studies in health and included the following steps: definition of the research question, structured data collection, and statistical analysis of results. Results: The total cost of HSCT was $155,110 ($92,794 ­ $249,146 USD). Matched unrelated donor HSCT was more expensive than matched related donor HSCT. The major cost factors involve post- -transplant complications, mainly the occurrence of infections. Concerning cost composition, exams and procedures represent the largest expense in HSCT (45%). Conclusion: These estimates could be applicable to further evaluations for HSCT cost-effectiveness and help healthcare decision-makers in middle-income countries

A post-incorporation study on the use of palivizumab in the Brazilian public health system.

Respiratory syncytial virus (RSV) is the main cause of lower respiratory disease in infants and children under five years of age. As there is no specific treatment for RSV infections, prophylaxis with the specific monoclonal antibody palivizumab (PVZ) has been widely recommended for high-risk cases during the RSV season. The present study aimed to evaluate the effectiveness of a public prophylaxis program with palivizumab on the incidence of hospitalizations for lower respiratory tract infections and RSV in children at high risk for severe RSV infections. A retrospective cohort study was carried out with preterm children or children under two years of age with chronic lung disease or hemodynamically significant congenital heart disease; the children were selected on the basis of their exposure status, which was defined as the prophylactic use of palivizumab during the RSV season. Children were enrolled retrospectively in two hospitals located in Southern Brazil, from May 2009 to August 2016. In a sample of 129 children, 69 (53.5%) received palivizumab and adherence to three or more doses was observed in 78%; 60 (46.5%) children did not receive palivizumab. PVZ prophylaxis was independently associated with a 66% reduction in hospitalizations for any cause (26/69 - 37.7%) in the PVZ group and 34/60 (56.7%) in the control group). A 52% reduction in hospitalizations due to lower respiratory tract infection was observed in the PVZ group (15/69 -21.7%) and 25/60 (41.7%) in the control group. These findings suggest that, for the group of studied patients, the adoption of an RSV prophylaxis scheme reached the same effectiveness as those described in previous clinical trials.

Brazilian guidelines for the management of brain-dead potential organ donors. The task force of the AMIB, ABTO, BRICNet, and the General Coordination of the National Transplant System.

OBJECTIVE: To contribute to updating the recommendations for brain-dead potential organ donor management. METHOD: A group of 27 experts, including intensivists, transplant coordinators, transplant surgeons, and epidemiologists, joined a task force formed by the General Coordination Office of the National Transplant System/Brazilian Ministry of Health (CGSNT-MS), the Brazilian Association of Intensive Care Medicine (AMIB), the Brazilian Association of Organ Transplantation (ABTO), and the Brazilian Research in Intensive Care Network (BRICNet). The questions were developed within the scope of the 2011 Brazilian Guidelines for Management of Adult Potential Multiple-Organ Deceased Donors. The topics were divided into mechanical ventilation, hemodynamic support, endocrine-metabolic management, infection, body temperature, blood transfusion, and use of checklists. The outcomes considered for decision-making were cardiac arrest, number of organs recovered or transplanted per donor, and graft function/survival. Rapid systematic reviews were conducted, and the quality of evidence of the recommendations was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Two expert panels were held in November 2016 and February 2017 to classify the recommendations. A systematic review update was performed in June 2020, and the recommendations were reviewed through a Delphi process with the panelists between June and July 2020. RESULTS: A total of 19 recommendations were drawn from the expert panel. Of these, 7 were classified as strong (lung-protective ventilation strategy, vasopressors and combining arginine vasopressin to control blood pressure, antidiuretic hormones to control polyuria, serum potassium and magnesium control, and antibiotic use), 11 as weak (alveolar recruitment maneuvers, low-dose dopamine, low-dose corticosteroids, thyroid hormones, glycemic and serum sodium control, nutritional support, body temperature control or hypothermia, red blood cell transfusion, and goal-directed protocols), and 1 was considered a good clinical practice (volemic expansion). CONCLUSION: Despite the agreement among panel members on most recommendations, the grade of recommendation was mostly weak. The observed lack of robust evidence on the topic highlights the importance of the present guideline to improve the management of brain-dead potential organ donors.

An 8-step framework for implementing time-driven activity-based costing in healthcare studies.

Micro-costing studies still deserving for methods orientation that contribute to achieve a patient-specific resource use level of analysis. Time-driven activity-based costing (TDABC) is often employed by health organizations in micro-costing studies with that objective. However, the literature shows many deviations in the implementation of TDABC, which might compromise the accuracy of the results obtained. One reason for that can be attributed to the non-existence of a step-by-step orientation to conduct cost analytics with the TDABC specific for micro-costing studies in healthcare. This article aimed at exploring the literature and practical cases to propose an eight-step framework to apply TDABC in micro-costing studies for health care organizations. The 8-step TDABC framework is presented and detailed exploring online spreadsheets already coded to demonstrate data structure and math formula building. A list of analyses that can be performed is suggested, including an explanation about the information that each analysis can provide to increase the organization capability to orient decision making. The case study developed show that actual micro-costing of health care processes can be achieved with the 8-step TDABC framework and its use in future researches can contribute to increase the number of studies that achieve high-quality level in cost information, and consequently, in health resource evaluation.

The cost of a disease targeted for elimination in Brazil: the case of schistosomiasis mansoni.

BACKGROUND: Schistosomiasis mansoni is a poverty-related parasitic infection that has a variety of clinical manifestations. We consider the disability and deaths caused by schistosomiasis unacceptable for a tool-ready disease. Its condition in Brazil warrants an analysis that will enable better understanding of the local health losses and contribute to the complex decision-making process. OBJECTIVE: This study estimates the cost of schistosomiasis in Brazil in 2015. METHODS: We conducted a cost of illness study of schistosomiasis mansoni in Brazil in 2015 based on a prevalence approach and from a societal perspective. The study included 26,499 schistosomiasis carriers, 397 hepatosplenic cases, 48 cases with the neurological form, 284 hospitalisations, and 11,368.26 years of life lost (YLL) of which 5,187 years are attributable to economically active age groups. RESULTS: The total cost of schistosomiasis mansoni in Brazil was estimated to be US$ 41,7million in 2015 with 94.61% of this being indirect costs. CONCLUSIONS: The economic burden of schistosomiasis mansoni in Brazil is high and results in the loss of productivity. Its persistence in Brazil is a challenge to public health and requires inter-sectorial interventions in areas such as indoor water supply, basic sanitation, and education.

Métodos: Um estudo de coorte prospectivo multicêntrico está sendo conduzido em dez unidades de terapia intensiva adulto clínico-cirúrgicas representativas das cinco regiões geopolíticas do Brasil. Pacientes com idade ≥ 18 anos que receberam alta das unidades de terapia intensiva participantes e permaneceram internados na unidade de terapia intensiva por 72 horas ou mais, nos casos de internação clínica ou cirúrgica de urgência, e por 120 horas ou mais, nos casos de internação cirúrgica eletiva, serão incluídos de forma consecutiva. Estes pacientes serão seguidos por 1 ano, por meio de entrevistas telefônicas estruturadas 3, 6 e 12 meses pós-alta da unidade de terapia intensiva. Dependência funcional, disfunção cognitiva, sintomas de ansiedade e depressão, sintomas de estresse pós-traumático, qualidade de vida relacionada à saúde, re-hospitalizações e mortalidade em longo prazo serão avaliados como desfechos. Discussão: O presente estudo tem o potencial de contribuir para o conhecimento a respeito da prevalência e dos fatores associados à síndrome pós-cuidados intensivos na população de pacientes adultos sobreviventes de internação em unidades de terapia intensiva brasileiras. Ademais, a associação entre síndrome pós-cuidados intensivos e qualidade de vida relacionada à saúde poderá ser estabelecida.

ABSTRACT Objective: To establish the prevalence of physical, cognitive and psychiatric disabilities, associated factors and their relationship with the qualities of life of intensive care survivors in Brazil. Methods: A prospective multicenter cohort study is currently being conducted at 10 adult medical-surgical intensive care units representative of the 5 Brazilian geopolitical regions. Patients aged ≥ 18 years who are discharged from the participating intensive care units and stay 72 hours or more in the intensive care unit for medical or emergency surgery admissions or 120 hours or more for elective surgery admissions are consecutively included. Patients are followed up for a period of one year by means of structured telephone interviews conducted at 3, 6 and 12 months after discharge from the intensive care unit. The outcomes are functional dependence, cognitive dysfunction, anxiety and depression symptoms, posttraumatic stress symptoms, health-related quality of life, rehospitalization and long-term mortality. Discussion: The present study has the potential to contribute to current knowledge of the prevalence and factors associated with postintensive care syndrome among adult intensive care survivors in Brazil. In addition, an association might be established between postintensive care syndrome and health-related quality of life.

Amiodarone for arrhythmia in patients with Chagas disease: A systematic review and individual patient data meta-analysis.

BACKGROUND: Chagas disease is a neglected chronic condition caused by Trypanosoma cruzi, with high prevalence and burden in Latin America. Ventricular arrhythmias are common in patients with Chagas cardiomyopathy, and amiodarone has been widely used for this purpose. The aim of our study was to assess the effect of amiodarone in patients with Chagas cardiomyopathy. METHODOLOGY: We searched MEDLINE, Embase and LILACS up to January 2018. Data from randomized and observational studies evaluating amiodarone use in Chagas cardiomyopathy were included. Two reviewers selected the studies, extracted data and assessed risk of bias. Overall quality of evidence was accessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE). PRINCIPAL FINDINGS: We included 9 studies (3 before-after studies, 5 case series and 1 randomized controlled trial). Two studies with a total of 38 patients had the full dataset, allowing individual patient data (IPD) analysis. In 24-hour Holter, amiodarone reduced the number of ventricular tachycardia episodes in 99.9% (95%CI 99.8%-100%), ventricular premature beats in 93.1% (95%CI 82%-97.4%) and the incidence of ventricular couplets in 79% (RR 0.21, 95%CI 0.11-0.39). Studies not included in the IPD analysis showed a reduction of ventricular premature beats (5 studies), ventricular tachycardia (6 studies) and ventricular couplets (1 study). We pooled the incidence of adverse side effects with random effects meta-analysis; amiodarone was associated with corneal microdeposits (61.1%, 95%CI 19.0-91.3, 5 studies), gastrointestinal events (16.1%, 95%CI 6.61-34.2, 3 studies), sinus bradycardia (12.7%, 95%CI 3.71-35.5, 6 studies), dermatological events (10.6%, 95%CI 4.77-21.9, 3 studies) and drug discontinuation (7.68%, 95%CI 4.17-13.7, 5 studies). Quality of evidence ranged from moderate to very low. CONCLUSIONS: Amiodarone is effective in reducing ventricular arrhythmias, but there is no evidence for hard endpoints (sudden death, hospitalization). Although our findings support the use of amiodarone, it is important to balance the potential benefits and harms at the individual level for decision-making.

Quality of life and quality-adjusted life years of chronic schistosomiasis mansoni patients in Brazil in 2015.

Background: Measures of health-related quality of life (HRQoL) have been used to express the impact of neglected diseases and to generate indicators for health economic assessments. Schistosomiasis mansoni is a neglected disease with various clinical manifestations, including severe repercussions, caused by parasitic worms. Here we describe the quality of life of chronic schistosomiasis mansoni patients and estimate the quality-adjusted life years (QALYs) associated with chronic schistosomiasis mansoni in Brazil in 2015. Methods: A HRQoL study was carried out using the three-level European Quality of Life 5-Dimensions (EQ-5D-3L) questionnaire in 147 chronic schistosomiasis mansoni patients at an outpatient monitoring facility of an endemic state for schistosomiasis. Results: Losses in HRQoL were observed in all five dimensions of the EQ-5D-3L. Patients >60 y and 40-49 y of age reported the highest frequencies of problems. The average utility index was 0.71, and the median index was significantly lower among female patients and patients with comorbidities (0.68; p<0.05) compared with the entire sample. Approximately 26.7 QALYs were estimated for the study population and 31.2 QALYs for the chronic schistosomiasis mansoni patients in Brazil. Conclusions: The advanced forms of schistosomiasis mansoni, even during treatment, contribute to important health losses in the population dealing with the disease.

Electronic Version of the EQ-5D Quality-of-Life Questionnaire: Adaptation to a Brazilian Population Sample.

OBJECTIVES: To assess the measurement equivalence of the original paper version of an adapted tablet version of the EuroQol five-dimensional questionnaire (EQ-5D). METHODS: A randomly selected sample of 509 individuals aged 18 to 64 years from the general population responded to the EQ-5D at two time points separated by a minimum interval of 24 hours and were allocated to one of the following groups: test-retest group (tablet-tablet) or crossover group (paper-tablet and tablet-paper). Agreement between methods was determined using the intraclass correlation coefficient (ICC) and the κ coefficient. RESULTS: In the crossover group, the following ICC values were obtained: 0.76 (confidence interval [CI] 0.58-0.89) for EQ-5D scores and 0.77 (CI 0.68-0.84) for visual analogue scale in subjects responding first to the tablet version; 0.83 (CI 0.75-0.89) for EQ-5D scores and 0.75 (CI 0.67-0.85) for visual analogue scale in subjects responding first to the paper version. In the test-retest group, the ICC was 0.85 (CI 0.73-0.91) for EQ-5D scores and 0.79 (CI 0.66-0.87) for visual analogue scale. The κ values were higher than 0.69 in this group. The internal consistencies of the paper and tablet methods were similar. CONCLUSIONS: The paper and tablet versions of the EQ-5D are equivalent. Test-retest and crossover agreement was high and the acceptability of the methods was similar among individuals.

In addition, an association might be established between postintensive care syndrome and health-related quality of life.

OBJETIVO: Avaliar a prevalência de incapacidades físicas, cognitivas e psiquiátricas, fatores associados e sua relação com qualidade de vida em pacientes sobreviventes de internação em unidades de terapia intensiva brasileiras. MÉTODOS: Um estudo de coorte prospectivo multicêntrico está sendo conduzido em dez unidades de terapia intensiva adulto clínico-cirúrgicas representativas das cinco regiões geopolíticas do Brasil. Pacientes com idade ≥ 18 anos que receberam alta das unidades de terapia intensiva participantes e permaneceram internados na unidade de terapia intensiva por 72 horas ou mais, nos casos de internação clínica ou cirúrgica de urgência, e por 120 horas ou mais, nos casos de internação cirúrgica eletiva, serão incluídos de forma consecutiva. Estes pacientes serão seguidos por 1 ano, por meio de entrevistas telefônicas estruturadas 3, 6 e 12 meses pós-alta da unidade de terapia intensiva. Dependência funcional, disfunção cognitiva, sintomas de ansiedade e depressão, sintomas de estresse pós-traumático, qualidade de vida relacionada à saúde, re-hospitalizações e mortalidade em longo prazo serão avaliados como desfechos. DISCUSSÃO: O presente estudo tem o potencial de contribuir para o conhecimento a respeito da prevalência e dos fatores associados à síndrome pós-cuidados intensivos na população de pacientes adultos sobreviventes de internação em unidades de terapia intensiva brasileiras. Ademais, a associação entre síndrome pós-cuidados intensivos e qualidade de vida relacionada à saúde poderá ser estabelecida.

Diretriz metodológica para estudos de avaliação econômica de tecnologias em saúde no Brasil / Methodological guidelines for economic evaluation studies of health technologies in Brazil

Objetivos: Resumir os principais pontos da Diretriz de Avaliação Econômica em Saúde (AES) do Ministério da Saúde. Métodos: As diretrizes para AES no Brasil foram desenvolvidas por intermédio de múltiplas rodadas de trabalho iterativas por grupo multidisciplinar de especialistas em economia da saúde e foram submetidas à consulta pública. Resultados: O problema deve ser definido por meio de uma questão de pesquisa estruturada. O estudo pode ser baseado em dados primários ou em modelagem, em que o primeiro aumenta a validade interna dos resultados e o segundo, a capacidade de generalização do estudo. Quando o trabalho for baseado em modelagem e focado em doença crônica, o modelo de Markov pode ser usualmente empregado, quando não houver necessidades que apontem para simulação de eventos discretos (como competição dos indivíduos por recursos escassos) ou modelos de transmissão dinâmica (em vacinação e/ou doenças infecciosas com alta transmissão entre indivíduos). O horizonte temporal preferencial é o de tempo de vida, e a taxa de desconto padrão é de 5% para custo e efetividade. Os custos devem representar a perspectiva do Sistema Único de Saúde (SUS), podendo ser estimados por macrocusteio ou microcusteio. Sempre que possível, os resultados devem ser apresentados no formato de custo por ano de vida salvo ajustado para qualidade, para facilitar comparações com outros estudos. Análises de sensibilidade devem ser extensamente empregadas, de forma a avaliar o impacto da incerteza nos resultados produzidos. Conclusões: Espera-se que, com a padronização da metodologia proposta na Diretriz, a produção de AES no país tenha incremento na sua qualidade e reprodutibilidade.

Objectives: To summarize the main points from the Brazilian's Ministry of Health Economic Evaluations (HEE) guideline. Methods: The guideline was developed through multiple rounds of iterative work, conducted by a multidisciplinary team of specialists in health economics, and where submitted to public consultation. Results: The decision problem should be defined through a structured research question. The study can be either primary data or model-based; in the first case, there is greater internal validity, while the second generates a superior generalizability. When the study is model-based and focused on a chronic disease, a Markov model can be usually employed, except for situations that points towards the need of a discrete event simulation (such as competition of individuals for scarce resources) or a dynamic transition model (for example, vaccination models and infectious diseases with high transmission rates between individuals). The preferred time horizon is the lifetime one, and the default discount rate is 5% for both costs and effectiveness. Costs should represent the Unified Health System (SUS) perspective and can be estimated through either gross-costing or micro-costing. Results should be presented as costs per quality adjusted life years (QALYs) whenever possible, to facilitate comparison with other studies. Sensitivity analyses should be widely employed, in order to evaluate the impact of uncertainty in the results produced by the model. Conclusions: It is expected that, with the standardization proposed in this guideline, the HEE production in Brazil has gains in quality and reproducibility.

Utility and quality-adjusted life-years in coronary artery disease: Five-year follow-up of the MASS II trial.

OBJECTIVES: This study evaluated the utility and quality-of-life year measurements for patients with coronary artery disease who underwent any of 3 therapeutic strategies with a 5-year follow-up. METHODS: Quality-of-life data were obtained from the Medicine, Angioplasty, or Surgery Study II trial. To obtain utilities, the 36-Item Short-Form questionnaire was converted to a 6-Dimensional Health State Classification System. RESULTS: Of the 611 initial patients, 579 completed the questionnaire. In all, 188 patients received the surgical treatment-194 the percutaneous, and the remaining 197 the medical. The median utility scores for the 5 years analyzed were 0.809 (95% confidence interval [CI] 0.794-0.842) for patients assigned to percutaneous coronary intervention, 0.755 (95% CI 0.723-0.774) for medical treatment, and 0.780 (95% CI 0.761-0.809) for coronary artery bypass graft surgery. The difference between percutaneous coronary intervention and medical treatment was statistically significant (P < .05, Dunn test). The median cumulative quality-of-life years across the 5 years were 3.802 (95% CI 3.668-3.936) for percutaneous, 3.540 (95% CI 3.399-3.681) for medical, and 3.764 (95% CI 3.638-3.890) for surgery. Additionally, the median quality-of-life years between percutaneous and medical treatment was 0.262 (95% CI 0.068-0.456), between surgery and medical treatment it was 0.224 (95% CI 0.036-0.413), and between surgery and percutaneous coronary intervention it was -0.038 (95% CI -0.221 to -0.146). CONCLUSION: Coronary artery bypass surgery and percutaneous coronary intervention were similar regarding cumulative quality-of-life years; however, they were both superior to that of medical treatment. The results presented are valuable data for further cost-utility studies.
