- Systematic Review of Health Economic Evaluations of Diagnostic Tests in Brazil: How accurate are the results?(2017) OLIVEIRA, Maria Regina Fernandes; LEANDRO, Roseli; DECIMONI, Tassia Cristina; ROZMAN, Luciana Martins; NOVAES, Hillegonda Maria Dutilh; SOAREZ, Patricia Coelho DeThe aim of this study is to identify and characterize the health economic evaluations (HEEs) of diagnostic tests conducted in Brazil, in terms of their adherence to international guidelines for reporting economic studies and specific questions in test accuracy reports. We systematically searched multiple databases, selecting partial and full HEEs of diagnostic tests, published between 1980 and 2013. Two independent reviewers screened articles for relevance and extracted the data. We performed a qualitative narrative synthesis. Forty-three articles were reviewed. The most frequently studied diagnostic tests were laboratory tests (37.2%) and imaging tests (32.6%). Most were non-invasive tests (51.2%) and were performed in the adult population (48.8%). The intended purposes of the technologies evaluated were mostly diagnostic (69.8%), but diagnosis and treatment and screening, diagnosis, and treatment accounted for 25.6% and 4.7%, respectively. Of the reviewed studies, 12.5% described the methods used to estimate the quantities of resources, 33.3% reported the discount rate applied, and 29.2% listed the type of sensitivity analysis performed. Among the 12 cost-effectiveness analyses, only two studies (17%) referred to the application of formal methods to check the quality of the accuracy studies that provided support for the economic model. The existing Brazilian literature on the HEEs of diagnostic tests exhibited reasonably good performance. However, the following points still require improvement: 1) the methods used to estimate resource quantities and unit costs, 2) the discount rate, 3) descriptions of sensitivity analysis methods, 4) reporting of conflicts of interest, 5) evaluations of the quality of the accuracy studies considered in the cost-effectiveness models, and 6) the incorporation of accuracy measures into sensitivity analyses.

A.; DECIMONI, T. C.; CAMPOLINA, A. G.- Higher MELD score increases the overall cost on the waiting list for liver transplantation: a micro-costing analysis based study(2017) TURRI, Jose Antonio Orellana; DECIMONI, Tassia Cristina; FERREIRA, Leandro Augusto; DINIZ, Marcio Augusto; HADDAD, Luciana Bertocco de Paiva; CAMPOLINA, Alessandro GonçalvesABSTRACT BACKGROUND: The pre-transplant period is complex and includes lots of procedures. The severity of liver disease predisposes to a high number of hospitalizations and high costs procedures. Economic evaluation studies are important tools to handle costs on the waiting list for liver transplantation. OBJECTIVE: The objective of the present study was to evaluate the total cost of the patient on the waiting list for liver transplantation and the main resources related to higher costs. METHODS: A cost study in a cohort of 482 patients registered on waiting list for liver transplantation was carried out. In 24 months follow-up, we evaluated all costs of materials, medicines, consultations, procedures, hospital admissions, laboratorial tests and image exams, hemocomponents replacements, and nutrition. The total amount of each resource or component used was aggregated and multiplied by the unitary cost, and thus individual cost for each patient was obtained. RESULTS: The total expenditure of the 482 patients was US$ 6,064,986.51. Outpatient and impatient costs correspond to 32.4% of total cost (US$ 1,965,045.52) and 67.6% (US$ 4,099,940.99) respectively. Main cost drivers in outpatient were: medicines (44.31%), laboratorial tests and image exams (31.68%). Main cost drivers regarding hospitalizations were: medicines (35.20%), bed use in ward and ICU (26.38%) and laboratorial tests (13.72%). Patients with MELD score between 25-30 were the most expensive on the waiting list (US$ 16,686.74 ± 16,105.02) and the less expensive were those with MELD below 17 (US$ 5,703.22 ± 9,318.68). CONCLUSION: Total costs on the waiting list for liver transplantation increased according to the patient’s severity. Individually, hospitalizations, hemocomponents reposition and hepatocellular carcinoma treatment were the main cost drivers to the patient on the waiting list. The longer the waiting time, the higher the total cost on list, causing greater impact on health systems.
- Many Miles to Go: A Systematic Review of the State of Cost-Utility Analyses in Brazil(2017) CAMPOLINA, Alessandro G.; ROZMAN, Luciana M.; DECIMONI, Tassia C.; LEANDRO, Roseli; NOVAES, Hillegonda M. D.; SOAREZ, Patricia Coelho DeBackground Little is known about the quality and quantity of cost-utility analyses (CUAs) in Brazil. Objective The objective of this study was to provide a systematic review of published CUAs of healthcare technologies in Brazil. Methods We performed a systematic review of economic evaluations studies published in MEDLINE, EMBASE, LILACS (Latin American and Caribbean Health Sciences Literature), SciELO (Scientific Electronic Library Online), NHS EED (National Health Service Economic Evaluation Database), HTA (Health Technology Assessment) Database, Web of Science, Scopus, Bireme (Biblioteca Regional de Medicina), BVS ECOS (Health Economics database of the Brazilian Virtual Library of Health), and SISREBRATS (Sistema de Informacao da Rede Brasileira de Avaliacao de Tecnologias em Saude [Brazilian Network for the Evaluation of Health Technologies]) from 1980 to 2013. Articles were included if they were CUAs according to the classification devised by Drummond et al. Two independent reviewers screened articles for relevance and carried out data extraction. Disagreements were resolved through discussion or through consultation with a third reviewer. We performed a qualitative narrative synthesis. Results Of the 535 health economic evaluations (HEEs) relating to Brazil, only 40 were CUAs and therefore included in the analysis. Most studies adhered to methodological guidelines for quality of reporting and 77.5% used quality-adjusted life-years (QALYs) as the health outcome. Of these studies, 51.6% did not report the population used to elicit preferences for outcomes and 45.2% used a specific population such as expert opinion. The preference elicitation method was not reported in 58.1% of these studies. The majority (80.6%) of studies did not report the instrument used to derive health state valuations and no publication reported whether tariffs (or preference weights) were national or international. No study mentioned the methodology used to estimate QALYs. Conclusions Many published Brazilian cost-utility studies adhere to key recommended general methods for HEE; however, the use of QALY calculations is far from being the current international standard. Development of health preferences research can contribute to quality improvement of health technology assessment reports in Brazil.
- A systematic review of health economic evaluations of vaccines in Brazil(2017) SARTORI, Ana Marli Christovam; ROZMAN, Luciana Martins; DECIMONI, Tassia Cristina; LEANDRO, Roseli; NOVAES, Hillegonda Maria Dutilh; SOAREZ, Patricia Coelho deBackground: In Brazil, since 2005, the Ministry of Health requires Health Economic Evaluation (HEE) of vaccines for introduction into the National Immunization Program.Objectives: To describe and analyze the full HEE on vaccines conducted in Brazil from 1980 to 2013.Methods: Systematic review of the literature. We searched multiple databases. Two researchers independently selected the studies and extracted the data. The methodological quality of individual studies was evaluated using CHEERS items.Results: Twenty studies were reviewed. The most evaluated vaccines were pneumococcal (25%) and HPV (15%). The most used types of HEE were cost-effectiveness analysis (45%) and cost-utility analysis (20%). The research question and compared strategies were stated in all 20 studies and the target population was clear in 95%. Nevertheless, many studies did not inform the perspective of analysis or data sources.Conclusions: HEE of vaccines in Brazil has increased since 2008. However, the studies still have methodological deficiencies.
