Mapping the characteristics, concepts and methodologies of matching-adjusted indirect comparison studies assessing pharmacological therapies in oncology: a scoping review protocol.

INTRODUCTION: Matching-adjusted indirect comparison (MAIC) studies are a subtype of indirect comparison, which uses propensity score weighting to enhance comparability. This method adjusts aggregated data based on covariables from individual patient data from studies to produce population-adjusted indirect comparisons. Some national Health Technology Assessment agencies have recently received submissions containing MAIC models. However, there can be a lack of confidence in its estimates when they are poorly reported and inconsistent with other techniques. The objective of this study is to map the characteristics, concepts and methodology of MAIC studies used for pharmacological therapies in the field of oncology. METHODS AND ANALYSIS: A scoping review methodology will be applied following the Joanna Briggs Institute framework and the results will be reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews. Studies that used MAIC to compare treatments in oncology conditions will be considered eligible. A systematic search will be conducted in PubMed, Embase and the Cochrane Library. No restriction of location or language will be applied. Study screening will be documented and presented in a Preferred Reporting Items for Systematic reviews and Meta-Analyses flow diagram. Data will be extracted and recorded on a predefined data form and will be presented in a tabular form accompanied by a descriptive summary. ETHICS AND DISSEMINATION: No ethical approval is required for this study. The results of this scoping review will be disseminated through peer-reviewed publications.

Economic burden of respiratory syncytial and parainfluenza viruses in children of upper-middle-income countries: a systematic review.

OBJECTIVE: To identify and assess the current evidence available about the costs of managing hospitalized pediatric patients diagnosed with Respiratory Syncytial Virus (RSV) and Parainfluenza Virus Type 3 (PIV3) in upper-middle-income countries. METHODS: The authors conducted a systematic review across seven key databases from database inception to July 2022. Costs extracted were converted into 2022 International Dollars using the Purchasing Power Parity-adjusted. PROSPERO identifier: CRD42020225757. RESULTS: No eligible study for PIV3 was recovered. For RSV, cost analysis and COI studies were performed for populations in Colombia, China, Malaysia, and Mexico. Comparing the total economic impact, the lowest cost per patient at the pediatric ward was observed in Malaysia ($ 347.60), while the highest was in Colombia ($ 709.66). On the other hand, at pediatric ICU, the lowest cost was observed in China ($ 1068.26), while the highest was in Mexico ($ 3815.56). Although there is no consensus on the major cost driver, all included studies described that the medications (treatment) consumed over 30% of the total cost. A high rate of inappropriate prescription drugs was observed. CONCLUSION: The present study highlighted how RSV infection represents a substantial economic burden to health care systems and to society. The findings of the included studies suggest a possible association between baseline risk status and expenditures. Moreover, it was observed that an important amount of the cost is destinated to treatments that have no evidence or support in most clinical practice guidelines.

Cost of Illness in Patients With COVID-19 Admitted in Three Brazilian Public Hospitals.

OBJECTIVES: The severity and transmissibility of COVID-19 justifies the need to identify the factors associated with its cost of illness (CoI). This study aimed to identify CoI, cost predictors, and cost drivers in the management of patients with COVID-19 from hospital and Brazil's Public Health System (SUS) perspectives. METHODS: This is a multicenter study that evaluated the CoI in patients diagnosed of COVID-19 who reached hospital discharge or died before being discharged between March and September 2020. Sociodemographic, clinical, and hospitalization data were collected to characterize and identify predictors of costs per patients and cost drivers per admission. RESULTS: A total of 1084 patients were included in the study. For hospital perspective, being overweight or obese, being between 65 and 74 years old, or being male showed an increased cost of 58.4%, 42.9%, and 42.5%, respectively. From SUS perspective, the same predictors of cost per patient increase were identified. The median cost per admission was estimated at US$359.78 and US$1385.80 for the SUS and hospital perspectives, respectively. In addition, patients who stayed between 1 and 4 days in the intensive care unit (ICU) had 60.9% higher costs than non-ICU patients; these costs significantly increased with the length of stay (LoS). The main cost driver was the ICU-LoS and COVID-19 ICU daily for hospital and SUS perspectives, respectively. CONCLUSIONS: The predictors of increased cost per patient at admission identified were overweight or obesity, advanced age, and male sex, and the main cost driver identified was the ICU-LoS. Time-driven activity-based costing studies, considering outpatient, inpatient, and long COVID-19, are needed to optimize our understanding about cost of COVID-19.

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.

Hospitalization costs of coronaviruses diseases in upper-middle-income countries: A systematic review.

BACKGROUND: COVID-19, SARS and MERS are diseases that present an important health burden worldwide. This situation demands resource allocation to the healthcare system, affecting especially middle- and low-income countries. Thus, identifying the main cost drivers is relevant to optimize patient care and resource allocation. OBJECTIVE: To systematically identify and summarize the current status of knowledge on direct medical hospitalization costs of SARS, MERS, or COVID-19 in Upper-Middle-Income Countries. METHODS: We conducted a systematic review across seven key databases (PubMed, EMBASE, BVS Portal, CINAHL, CRD library, MedRxiv and Research Square) from database inception to February 2021. Costs extracted were converted into 2021 International Dollars using the Purchasing Power Parity-adjusted. The assessment of quality was based on the protocol by the BMJ and CHEERS. PROSPERO 2020: CRD42020225757. RESULTS: No eligible study about SARS or MERS was recovered. For COVID-19, five studies presented cost analysis performed in Brazil, China, Iran, and Turkey. Regarding total direct medical costs, the lowest cost per patient at ward was observed in Turkey ($900.08), while the highest in Brazil ($5,093.38). At ICU, the lowest was in Turkey ($2,984.78), while the highest was in China ($52,432.87). Service care was the most expressive (58% to 88%) cost driver of COVID-19 patients at ward. At ICU, there was no consensus between service care (54% to 87%) and treatment (72% to 81%) as key burdens of total cost. CONCLUSION: Our findings elucidate the importance of COVID-19 on health-economic outcomes. The marked heterogeneity among studies leaded to substantially different results and made challenging the comparison of data to estimate pooled results for single countries or regions. Further studies concerning cost estimates from standardized analysis may provide clearer data for a more substantial analysis. This may help care providers and policy makers to organize care for patients in the most efficient way.

Drug interactions for elderly with respiratory disorders and times of covid-19: a systematic scoping review / Interacciones farmacológicas para ancianos con enfermedades respiratorias y tiempos de covid-19: una revisión sistemática del alcance

Background: The elderly people have high morbimortality associated with respiratory disorders, in addition to the presence of other safety risk factors, such as the use of potentially inappropriate medication and the occurrence of drug interactions. Objective: Considering the current pandemic scenario, it was intended to identify explicit criteria-based tools that reported drug interactions between potentially inappropriate medication and respiratory system disorders and possibly worse prognosis of COVID-19 infection. Methods: A systematic scoping review was conducted until February 2020. Study characteristics of explicit criteria-based tools, and potentially inappropriate medication, drug interactions, and therapeutic management, were extracted. Results: Nineteen explicit criteria-based tools were included. Nineteen drug interactions and 17 potentially inappropriate medications with concerns for three respiratory disorders (asthma, chronic pulmonary obstructive disease, and respiratory failure) were identified. The most frequent pharmacological classes reported were benzodiazepines and beta-blockers. For clinical management, the tools recommend using cardioselective beta-blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, and angiotensin II type I receptor blockers and benzodiazepines with a short or intermediate half-life. Conclusion: Considering the increased risk of COVID-19 infection in the elderly, drug interactions and the use of potentially inappropriate medication associated with the occurrence of adverse drug events in the respiratory system may also worsening COVID-19 infection in patients with uncontrolled respiratory disorders. Thus, it is essential to assess drug therapy in use, to identify safety risks and monitor the elderly in general and those with a worse prognosis concerning COVID-19, promoting patient safety.

Antecedentes: Los ancianos tienen alta morbimortalidad asociada a trastornos respiratorios, además de la presencia de otros factores de riesgo de seguridad, como el uso de medicación potencialmente inapropiada y la ocurrencia de interacciones medicamentosas. Objetivo: Teniendo en cuenta el escenario pandémico actual, se pretendía identificar herramientas explícitas basadas en criterios que informaran interacciones farmacológicas entre medicamentos potencialmente inapropiados y trastornos del sistema respiratorio y posiblemente un peor pronóstico de la infección por COVID-19. Métodos:Se realizó una revisión sistemática del alcance hasta febrero de 2020. Se extrajeron las características del estudio de las herramientas explícitas basadas en criterios y la medicación potencialmente inapropiada, las interacciones entre medicamentos y el manejo terapéutico. Resultados: Se incluyeron diecinueve herramientas explícitas basadas en criterios. Se identificaron diecinueve interacciones farmacológicas y 17 medicamentos potencialmente inapropiados con preocupaciones por tres trastornos respiratorios (asma, enfermedad pulmonar obstructiva crónica e insuficiencia respiratoria). Las clases farmacológicas más frecuentes comunicadas fueron las benzodiacepinas y los betabloqueantes. Para el manejo clínico, las herramientas recomiendan el uso de betabloqueantes cardioselectivos, bloqueadores de los canales de calcio, inhibidores de la enzima convertidora de angiotensina y bloqueadores del receptor de angiotensina II tipo I y benzodiacepinas con una vida media corta o intermedia. Conclusión: Teniendo en cuenta el mayor riesgo de infección por COVID-19 en los ancianos, las interacciones farmacológicas y el uso de medicamentos potencialmente inapropiados asociados con la aparición de eventos farmacológicos adversos en el sistema respiratorio también pueden empeorar la infección por COVID-19 en pacientes con trastornos respiratorios no controlados. Por tanto, es fundamental evaluar la farmacoterapia en uso, identificar los riesgos de seguridad y monitorizar a los ancianos en general y a aquellos con peor pronóstico en relación con el COVID-19, promoviendo la seguridad del paciente.

Brazilian Analytical Decision Model for Cardiovascular Disease: An Adaptation of the Scottish Cardiovascular Disease Policy Model.

INTRODUCTION: Despite the significant impact of cardiovascular disease (CVD), there is not yet an analytical decision tool for assessing efficiency of interventions to prevent primary CVD events in Brazil. Therefore, we sought to adapt a Scottish CVD Policy Model to be used in the proposed population. METHODS: Calibration consisted of identifying multiplicative factors for linear predictors of existing survival analysis models to produce predictions that closely match observed data (Life-table and Brazilian cohort study). Target data were life expectancy (LE) and cumulative incidence of coronary heart disease (CHD), cerebrovascular disease (CBVD), fatal CVD and fatal non-CVD. Root-Mean-Square-Error (RMSE) was used to estimate differences between predictions and observations. Acceptance criteria were defined as a fit of less than one year for LE and 1% for cumulative incidence. Male and female models were built separately. RESULTS: The original model underestimated LE (RMSE=2.85 for men and 1.91 for women), CHD and CBVD for women (RMSE=0.044 and 0.041, respectively). The calibration process identified multiplicative factors to reach acceptance criteria for the four target data mentioned above (RMSE=0.61, 0.21, 0.016 and 0.017, respectively). Over prediction was identified only for CHD events in men (RMSE=0.031) being further calibrated (RMSE=0.008). All other target data met the acceptance criteria. Overall, the calibrated model predicts properly to individuals aging 35-80 years old, diabetics or not, smokers or not, with or without family history of CVD, and presenting at least one of the risk factors uncontrolled: Systolic Blood Pressure, Total Cholesterol or HDL-Cholesterol. DISCUSSION: This is the first decision analytic model capable of assessing efficiency of interventions that prevent primary CVD events in Brazil. In future research, independent external validation should be carried out to corroborate the reliability of the model outputs.

Análise de impacto orçamentário: uma revisão prática de conceitos e aplicações para o gestor / Budget impact analysis: a practical review of concepts and applications for the manager

Avaliações econômicas em saúde são essenciais para a tomada de decisão de gestores, visto que as inovações no setor nem sempre podem ser incorporadas conforme as expectativas dos usuários e da indústria. Logo, a análise de impacto orçamentário (AIO), uma das principais ferramentas da avaliação de tecnologias em saúde (ATS), permite aos gestores estimar o potencial número de indivíduos elegíveis para determinada tecnologia ao longo dos anos, prever quanto será necessário gastar para incorporar a tecnologia ou, eventualmente, se haverá economia nos cofres do pagador com a inclusão dela. Com a crescente publicação de artigos científicos sobre AIO no Brasil, surge a preocupação a respeito da qualidade metodológica desses estudos. O objetivo desta revisão é apresentar recomendações-chave para a elaboração de uma AIO adequada e expor a utilidade prática da AIO para a tomada de decisão de gestores de saúde por meio da análise de quatro estudos publicados. O formato de apresentação de uma AIO possibilita rápido entendimento e possui atributos que permitem evidenciar o maior valor de produtos e serviços de saúde junto aos tomadores de decisão em saúde, contribuindo para as melhores escolhas do ponto de vista clínico e econômico, nos sistemas público e privado. Porém, cabe ressaltar que alguns estudos ainda carecem de evidências de mundo real ou dados epidemiológicos para as estimativas e trabalham de maneira insuficiente as ferramentas para a redução de incertezas paramétricas.

Health economics evaluations are essential for decision makers, since innovations can not always be incorporated according to expectations of users and industry. Therefore, the Budget Impact Analysis (BIA), one of the main tools in Health Technology Assessment (HTA), allows managers to estimate the potential number of individuals eligible for a given technology over the years, to predict how much it will be necessary to spend for incorporate the technology or, eventually, whether there will be savings in the payer's coffers with the inclusion of the same. With the growing publication of scientific articles on BIA in Brazil, there is concern about the methodological quality of these studies. The objective of this review is to present key recommendations to elaborate an adequate BIA, commenting on four published studies, aiming to expose the practical utility of BIA for health managers. The presentation format of the BIA provides a quick understanding and has attributes that allows evidence of the highest value of health products and services among health decision makers, contributing to the best clinical and economic choices in public and private health systems. However, it should be noted in some studies there is still a lack of real-world evidence or epidemiological data for the estimates and insufficient using of tools to reduce parametric uncertainties.

Assessment tool for potentially inappropriate medication use in the elderly: a scoping review protocol

Potentially Inappropriate Medication for the elderly (PIM) are drugs in which the safety risks may exceed the benefits, especially when there are safer alternatives. The use of PIM is associated with increased hospitalizations and it is estimated that one every five prescriptions presents at least one PIM. In this context, there are several assessment tools for identification of PIM. The first assessment tool developed was Beers criteria and since its publication, new tools have been developed. The objective of this scoping review is to explore studies presenting assessment tools of PIM to map characteristics, justifications, and therapeutic equivalents. This review will consider studies that developed or validated an assessment tool of PIM. Electronic searches will be performed in PubMed and Scopus with no time limit. Two researchers, independently, will select registries and extract data of studies and tool characteristics, PIM and potentially inappropriate interaction, condition, justification, and therapeutic equivalents. The findings will be presented in narrative form including tables and figures to aid in data presentation, where appropriate.(AU)

Multicriteria decision analysis for health care decision making in Brazil: a scoping review

Everyday health care professionals and managers are invited to make complex decisions involving multiple factors and alternatives with impacts on the health of the interested population. In this sense, the multicriteria decision analysis (MCDA) considers the perception of different stakeholders about multiple attributes that can affect decision making, thus representing a decision support tool. Despite the relevance of MCDA, little is known about the application of different methods in health care in Brazil. To identify the characteristics of the Brazilian publications about MCDA in health care. A scoping review was conducted in PubMed, Scopus, and LILACS. Published primary studies, regardless of language, were included. This scoping review identified 45 studies in databases and one by manual search. Of these, 14 studies were evaluated by eligibility and included in scoping review: most of the publications were developed in health services (n=6) using MACBETH technic (n=6), including different actors (n=11), mainly for performance evaluation (n=6). Besides MACBETH, other methods of MCDA were TODIM (Interactive and Multicriteria Decision Making, in English), analytic hierarchy process, and discrete choice experiment. It was identified that the application of MCDA is still incipient in Brazilian health care. This review may contribute to the dissemination of knowledge about these methods and possibilities of applications among health professionals, as well as to alert them to the importance of using ethical, consistent and objective tools for more robust and transparent decision making.(AU)

[Household storage and use of medications in a population served by the family health strategy in Brazil]. / Estoque doméstico e uso de medicamentos em uma população cadastrada na estratégia saúde da família no Brasil.

OBJECTIVE: To identify families served by the family health strategy (FHS) storing medicines at home, to evaluate storage conditions, and to investigate medicine use practices. METHODS: The study was conducted in a municipality in the state of São Paulo with two FHS units serving 1 867 households. The sample was selected by means of stratified random sampling. Data collection was conducted through semistructured interviews from July to October 2008. RESULTS: One resident was interviewed in each of the 280 households visited. Medicines were found in 255 households (91.1%). Of 326 storage locations, 217 (75.8%) were inadequate (easily accessible to children or exposed to moisture, light). Of the 2 578 medicines identified, 2 059 medicines (79.9%) in 236 (84.3%) households had safety or identification problems. Of the 280 respondents, 179 (63.9%) used medications. Of these, 24 were self-medicating, only one with an over-the-counter drug. Only 44 users had the prescription for their medication, and 21 did not follow the prescription in terms of dosage or had interrupted the treatment. CONCLUSIONS: Non-adherence to recommended treatment can lead to negative outcomes, such as inefficiency (using dosages lower than prescribed), poisoning (using dosages higher than prescribed), and other adverse reactions.

Estoque doméstico e uso de medicamentos em uma população cadastrada na estratégia saúde da família no Brasil / Household storage and use of medications in a population served by the family health strategy in Brazil

OBJETIVO: Identificar domicílios atendidos pela estratégia saúde da família (ESF) que possuíam estoque de medicamentos, avaliar as condições de armazenamento e conhecer o modo de uso dos medicamentos. MÉTODOS: O estudo foi conduzido em um município do Estado de São Paulo que possui duas unidades da ESF, com 1 867 domicílios cadastrados; a amostra foi definida por meio de sorteio aleatório estratificado. A coleta de dados foi realizada por meio de entrevistas semiestruturadas de julho a outubro de 2008. RESULTADOS: Foi entrevistado um morador em cada um dos 280 domicílios visitados. Foram encontrados medicamentos em 255 domicílios (91,1 por cento). Dos 326 locais de guarda de medicamentos, 217 (75,8 por cento) eram inadequados (de fácil acesso a crianças ou expostos a umidade, luz). Das 2 578 especialidades farmacêuticas encontradas, 2 059 (79,9 por cento) tinham algum problema de segurança ou identificação, o que foi observado em 236 (84,3 por cento) domicílios. Dos 280 entrevistados, 179 (63,9 por cento) eram usuários de medicamentos. Desses, 24 estavam se automedicando, apenas um com medicamento que não exigia prescrição. Somente 44 usuários tinham a prescrição do medicamento. O medicamento era usado de forma diferente da prescrição por 21 entrevistados, por desacordo posológico ou interrupção do tratamento. CONCLUSÕES: A maioria dos domicílios estudados armazenava os medicamentos de forma inadequada. As discordâncias em relação às orientações médicas prescritas podem levar a resultados negativos, como ineficácia por uso de doses abaixo do prescrito, intoxicações por doses acima do prescrito, reações adversas e não adesão terapêutica.
