The cost of oral cancer: A systematic review.

Although clinical and epidemiological aspects of oral cancers (OC) are well-documented in the literature, there is a lack of evidence on the economic burden of OC. This study aims to provide a comprehensive systematic assessment on the economic burden of OC based on available evidence worldwide. A systematic review was conducted. The population was any individual, who were exposed to OC, considered here as lip (LC), oral cavity (OCC), or oropharynx (OPC) cancer. The outcome was information on direct (medical and non-medical) and indirect (productivity loss and early death) costs. The data sources included Scopus, Web of Science, Cochrane, BVS, and NHS EED. A search of grey literature (ISPOR and INAHTA proceedings) and a manual search in the reference lists of the included publications were performed (PROSPERO no. CRD42020172471). We identified 24 studies from 2001 to 2021, distributed by 15 countries, in 4 continents. In some developed western countries, the costs of LC, OCC, and OPC reached an average of Gross Domestic Product per capita of 18%, 75%, and 127%, respectively. Inpatient costs for OC and LC were 968% and 384% higher than those for outpatients, respectively. Advanced cancer staging was more costly (from ~22% to 373%) than the early cancer staging. The economic burden of oral cancer is substantial, though underestimated.

Direct healthcare costs of lip, oral cavity and oropharyngeal cancer in Brazil.

The efficiency of public policies includes the measurement of the health resources used and their associated costs. There is a lack of studies evaluating the economic impact of oral cancer (OC). This study aims to estimate the healthcare costs of OC in Brazil from 2008 to 2016. This is a partial economic evaluation using the gross costing top-down method, considering the direct healthcare costs related to outpatients, inpatients, intensive care units, and the number of procedures, from the perspective of the public health sector. The data were extracted from the Outpatient and Inpatient Information System of the National Health System, by diagnosis according to the 10th Revision of the International Classification of Diseases, according to sites of interest: C00 to C06, C09 and C10. The values were adjusted for annual accumulated inflation and expressed in 2018 I$ (1 I$ = R$2,044). Expenditure on OC healthcare in Brazil was I$495.6 million, which was composed of 50.8% (I$251.6 million) outpatient and 49.2% (I$244.0 million) inpatient healthcare. About 177,317 admissions and 6,224,236 outpatient procedures were registered. Chemotherapy and radiotherapy comprised the largest number of procedures (88.8%) and costs (94.9%). Most of the costs were spent on people over 50 years old (72.9%) and on males (75.6%). Direct healthcare costs in Brazil for OC are substantial. Outpatient procedures were responsible for the highest total cost; however, inpatient procedures had a higher cost per procedure. Men over 50 years old consumed most of the cost and procedures for OC. The oropharynx and tongue were the sites with the highest expenditure. Further studies are needed to investigate the cost per individual, as well as direct non-medical and indirect costs of OC.

Delivering maternal and childcare at primary healthcare level: The role of PMAQ as a pay for performance strategy in Brazil.

BACKGROUND: Improving access and quality in health care is a pressing issue worldwide and pay for performance (P4P) strategies have emerged as an alternative to enhance structure, process and outcomes in health. In 2011, Brazil adopted its first P4P scheme at national level, the National Programme for Improving Primary Care Access and Quality (PMAQ). The contribution of PMAQ in achieving the Sustainable Development Goals related to maternal and childcare remains under investigated in Brazil. OBJECTIVE: To estimate the association of PMAQ with the provision of maternal and childcare in Brazil, controlling for socioeconomic, geographic and family health team characteristics. METHOD: We used cross-sectional quantile regression (QR) models for two periods, corresponding to 33,368 Family Health Teams (FHTs) in the first cycle and 39,211 FHTs in the second cycle of PMAQ. FHTs were analysed using data from the Brazilian Ministry of Health (SIAB and CNES) and the Brazilian Institute for Geography and Statistics (IBGE). RESULTS: The average number of antenatal consultations per month were positively associated with PMAQ participating teams, with larger effect in the lower tail (10th and 25th quantiles) of the conditional distribution of the response variable. There was a positive association between PMAQ and the average number of consultations under 2 years old per month in the 10th and 25th quantiles, but a negative association in the upper tail (75th and 90th quantiles). For the average number of physician consultations for children under 1 year old per month, PMAQ participating teams were positively associated with the response variable in the lower tail, but different from the previous models, there is no clear evidence that the second cycle gives larger coefficients compared with first cycle. CONCLUSION: PMAQ has contributed to increase the provision of care to pregnant women and children under 2 years at primary healthcare level. Teams with lower average number of antenatal or child consultations benefited the most by participating in PMAQ, which suggests that PMAQ might motivate worse performing health providers to catch up.

Public engagement in health technology assessment in Brazil: the case of the Trastuzumab public consultation.

BACKGROUND: Public engagement in health technology assessment (HTA) is increasing worldwide. There are several forms of public engagement and it is not always possible to determine which stakeholders participate in the HTA process and how they contribute. Our objective was to investigate which types of social representatives contributed to the public consultation on the incorporation of Trastuzumab for early-stage breast cancer treatment within the public health system in Brazil, held in 2012 by the National Committee for Health Technology Incorporation (CONITEC). METHODS: A mixed methods approach was used to analyze social representativeness and the composition of the corpus from the public consultation, which consisted of 127 contributions. Three types of analysis were performed using IRaMuTeQ software: classic lexical analysis, descending hierarchical classification and specificities analysis. The contributions were clustered according to the main categories of discourse observed, into four social representation categories: 1) patient representation/advocacy; 2) pharmaceutical industry/advocacy; 3) healthcare professionals; and 4) individual contributions. RESULTS: Category 1 contained words related to increased survival due to use of the drug and a low score for words pertaining to studies on Trastuzumab. The word "safety" obtained a positive score only in category 2, which was also the only category that exhibited a negative score for the word "risk". Category 3 displayed the lowest scores for "diagnosis" and "safety". The word "efficacy" had a negative score only in category 4. CONCLUSIONS: Each category exhibited different results for words related to health systems and to key concepts linked to HTA. Our analysis enabled the identification of the most prominent contributions for each category. Despite the promising results obtained, further research is needed to validate this software for use in analyzing public contributions.

Cost-Utility of Gastric Bypass Surgery Compared to Clinical Treatment for Severely Obese With and Without Diabetes in the Perspective of the Brazilian Public Health System.

PURPOSE: Obesity is associated with increased morbidity and mortality. Weight loss due to gastric bypass (GBP) surgery improves clinical outcomes and may be a cost-effective intervention. To estimate the cost-effectiveness of GBP compared to clinical treatment in severely obese individuals with and without diabetes in the perspective of the Brazilian public health system. MATERIALS AND METHODS: A Markov model was developed to compare costs and outcomes of gastric bypass in an open approach to clinical treatment. Health states were living with diabetes, remission of diabetes, non-fatal and fatal myocardial infarction, and death. We also included the occurrence of complications related to surgery and plastic surgery after the gastric bypass surgery. The direct costs were obtained from primary data collection performed in three public reference centers for obesity treatment. Utility values also derived from this cohort, while transition probabilities came from the international literature. A sensitivity analysis was performed to evaluate uncertainties. The model considered a 10-year time horizon and a 5% discount rate. RESULTS: Over 10 years, GBP increased quality-adjusted life years (QALY) and costs compared to clinical treatment, resulting in an incremental cost-effectiveness ratio (ICER) of Int$1820.17/QALY and Int$1937.73/QALY in individuals with and without diabetes, respectively. Sensitivity analysis showed that utility values and direct costs of treatments were the parameters that affected the most the ICERs. CONCLUSION: The study demonstrated that GBP is a cost-effective intervention for severely obese individuals in the Brazilian public health system perspective, with a better result in individuals with diabetes.

Estimated Costs of Clinical and Surgical Treatment of Severe Obesity in the Brazilian Public Health System.

BACKGROUND: Obesity is a major global epidemic and a burden to society and health systems. This study aimed to estimate and compare the anual costs of clinical and surgical treatment of severe obesity from the perspective of the Brazilian Public Health System. METHODS: An observational and cross-sectional study was performed in three reference centers. Data collection on health resources utilization and productivity loss was carried out through an online questionnaire. Participants were divided in clinical (waiting list for a bariatric surgery) and surgical groups (open Roux-en-Y gastric bypass), and then allocated by the time of surgery (up to 1 year; 1-2 years; 2-3 years; and >3 years). Costs of visits, medications, exams, and surgeries were obtained from government sources. Data on non-medical costs, such as transportation, special diets, and caregivers, were also colleted. Productivity loss was estimated using self-reported income. Costs in local currency (Real) were converted to international dollars (Int$ 2015). RESULTS: Two hundred and seventy-four patients, 140 in surgical group and 134 in clinical group were included. In first postoperative year, the surgical group had higher costs than clinical group (Int$6005.47 [5000.18-8262.36] versus 2148.14 [1412.2-3506.8]; p = 0.0002); however, from the second year, the costs decreased progressively. In the same way, indirect costs decreased significantly after surgery (259.08 [163.63-662.72] versus 368.17 [163.62-687.27]; p = 0.06). CONCLUSION: Total costs were higher in the surgical group in the first 2 years after surgery. However, from the third year on, the costs were lower than in the clinical group.

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.

Spending on Bariatric Surgery in the Unified Health System from 2010 to 2014: a Study Based on the Specialist Hospitals Authorized by the Ministry of Health.

BACKGROUND: The aim of this study is to analyze the production of 76 specialist hospitals for the morbidly obese in Brazil's public healthcare system (SUS) from 2010 to 2014 in terms of quantity and costs of bariatric surgery and its complications. METHODS: Secondary data from the SUS Hospital Information System and the National Healthcare Establishments Registry were used. Current spending on bariatric surgery and its medical and postoperative complications were analyzed. RESULTS: There was a 60 % rise in the number of surgeries between 2010 and 2014. This increase was not homogeneous among the hospitals studied, since only 19 performed the minimum number of surgeries required. Women accounted for 85 % of the surgeries carried out, and 32 % were aged between 35 and 44 years. The Roux-en-Y technique was the most widely used (93.7 % of the total), followed by sleeve gastrectomy. The ratio between the occurrence of medical complications and total number of surgeries performed in each hospital varied significantly (between 0 and 5.97 %) but was lower for postoperative complications, ranging from 0 to 1.7 %. There was a nominal increase of 44 % in average expenditure on postoperative complications between 2013 and 2014, while the average cost of medical complications decreased by 8.7 % in the same period. CONCLUSIONS: Despite the rise in the number of bariatric surgeries in Brazil, there is still a high demand for surgeries that is not being met, while most specialist hospitals fail to perform the minimum number of surgeries stipulated by the Ministry of Health.

Direct healthcare cost of obesity in brazil: an application of the cost-of-illness method from the perspective of the public health system in 2011.

BACKGROUND: Obesity is a global public health problem and a risk factor for several diseases that financially impact healthcare systems. OBJECTIVE: To estimate the direct costs attributable to obesity (body mass index {BMI} ≥ 30 kg/m2) and morbid obesity (BMI ≥ 40 kg/m2) in adults aged ≥ 20 incurred by the Brazilian public health system in 2011. SETTINGS: Public hospitals and outpatient care. METHODS: A cost-of-illness method was adopted using a top-down approach based on prevalence. The proportion of the cost of each obesity-associated comorbidity was calculated and obesity prevalence was used to calculate attributable risk. Direct healthcare cost data (inpatient care, bariatric surgery, outpatient care, medications and diagnostic procedures) were extracted from the Ministry of Health information systems, available on the web. RESULTS: Direct costs attributable to obesity totaled US$ 269.6 million (1.86% of all expenditures on medium- and high-complexity health care). The cost of morbid obesity accounted for 23.8% (US$ 64.2 million) of all obesity-related costs despite being 18 times less prevalent than obesity. Bariatric surgery costs in Brazil totaled US$ 17.4 million in 2011. The cost of morbid obesity in women was five times higher than it was in men. CONCLUSION: The cost of morbid obesity was found to be proportionally higher than the cost of obesity. If the current epidemic were not reversed, the prevalence of obesity in Brazil will increase gradually in the coming years, as well as its costs, having serious implications for the financial sustainability of the Brazilian public health system.
