Comparison of EQ-5D Values Sets Among South American Countries.

OBJECTIVE: Social health preference sets are necessary for conducting health economic evaluations. Values from other countries are often used when local sets are not available, which may alter the results. We aimed to evaluate the degree of variability of currently available country-specific value sets of the EuroQol EQ-5D instrument from South American countries (SAC). METHODS: We selected EQ-5D value sets from SAC and 2 reference countries. We obtained crosswalk value sets for the countries that use the EQ-5D-3L instrument. We compared the value sets with the Kruskal-Wallis test and then carried out pairwise comparisons with the Sign test. We also assessed correlations among the countries' value sets using the Spearman test. We calculated the absolute difference across countries for each health state, considering a difference of greater than 0.05 relevant. RESULTS: The range of value sets varied greatly. The Peruvian value set had the widest range (1 to -1.076) and the lowest values (median: 0.055; interquartile range: -0.171 to 0.275). The Ecuadorian set had the highest values (median: 0.587; interquartile range: 0.443-0.704). The Peruvian value set also had the greatest proportion of health states (43.6%) with a negative value, and the Uruguayan set had the smallest proportion (0.9%). Differences among countries were significant in all cases, with the greatest difference between Ecuador and Peru (median difference: 0.495; 95% confidence interval: 0.515-0.528). CONCLUSION: Social health preference sets varied greatly among SAC. Using non-local values could distort resource allocation decisions; hence, we recommend that countries obtain and use local value sets.

HEALTH TECHNOLOGY ASSESSMENT FOR DECISION MAKING IN LATIN AMERICA: GOOD PRACTICE PRINCIPLES.

OBJECTIVES: The aim of this study was to identify good practice principles for health technology assessment (HTA) that are the most relevant and of highest priority for application in Latin America and to identify potential barriers to their implementation in the region. METHODS: HTA good practice principles proposed at the international level were identified and then explored during a deliberative process in a forum of assessors, funders, and product manufacturers. RESULTS: Forty-two representatives from ten Latin American countries participated. Good practice principles proposed at the international level were considered valid and potentially relevant to Latin America. Five principles were identified as priority and with the greatest potential to be strengthened at this time: transparency in the production of HTA, involvement of relevant stakeholders in the HTA process, mechanisms to appeal decisions, clear priority-setting processes in HTA, and a clear link between HTA and decision making. The main challenge identified was to find a balance between the application of these principles and the available resources in a way that would not detract from the production of reports and adaptation to the needs of decision makers. CONCLUSIONS: The main recommendation was to progress gradually in strengthening HTA and its link to decision making by developing appropriate processes for each country, without trying to impose, in the short-term, standards taken from examples at the international level without adequate adaptation of these to local contexts.

OBJECTIVE: Identify the most relevant, applicable, and priority good practice principles in health technology assessment (HTA) in Latin America, and potential barriers to implementing them in the region. METHODS: HTA good practice principles postulated worldwide were identified and then explored through a deliberative process in a forum of evaluators, funders, and technology producers. RESULTS: Forty-two representatives from ten Latin American countries participated in the forum. The good practice principles postulated at the international level were considered valid and potentially applicable in Latin America. Five principles were identified as priorities and as having greater potential to be expanded at this time: transparency in carrying out HTA; involvement of stakeholders in the HTA process; existence of mechanisms to appeal decisions; existence of clear mechanisms for HTA priority-setting; and existence of a clear link between assessment and decision-making. The main challenge identified was to find a balance between application of these principles and available resources, to prevent the planned improvements from jeopardizing report production times and failing to meet decision-makers' needs. CONCLUSIONS: The main recommendation was to gradually advance in improving HTA and its link to decision-making by developing appropriate processes for each country, without attempting to impose, in the short term, standards taken from examples at the international level without adequate adaptation to the local context.

Evaluación de tecnologías sanitarias para la toma de decisiones en Latinoamérica: principios de buenas prácticas

Objetivo. Identificar los principios de buenas prácticas en la Evaluación de las Tecnologías Sanitarias (ETESA) más relevantes, aplicables y prioritarios en Latinoamérica; y las potenciales barreras para implementarlos en la región. Métodos. Se identificaron los principios de buenas prácticas en ETESA postulados a nivel mundial y luego se exploraron mediante un proceso deliberativo en un Foro de evaluadores, financiadores y productores de tecnologías. Resultados. El Foro contó con la participación de 42 representantes de diez países Latinoamericanos. Los principios de buenas prácticas postulados a nivel internacional fueron considerados válidos y potencialmente aplicables en Latinoamérica. Cinco principios fueron identificados como prioritarios y con mayor potencial para ser profundizados en estos momentos: transparencia en los procesos de realización de ETESA; Involucramiento de actores relevantes en el proceso de ETESA; existencia de mecanismos de apelación de las decisiones; existencia de mecanismos claros para el establecimiento de prioridades en ETESA; y existencia de un vínculo claro entre la evaluación y la toma de decisión. El principal reto identificado fue encontrar un equilibrio entre la aplicación de estos principios y los recursos disponibles para prevenir que las mejoras a introducir atenten contra los tiempos de producción de informes y la adecuación a las necesidades de los decisores. Conclusiones. La principal recomendación fue avanzar gradualmente en mejorar la ETESA y su vínculo con la toma de decisión desarrollando procesos apropiados para cada país, sin pretender imponer a corto plazo estándares tomados de ejemplos a nivel internacional sin la adecuada adaptación al contexto local.

Argentine valuation of the EQ-5D health states.

OBJECTIVE: To develop a set of health state values based on EuroQol EQ-5D instrument for the Argentine general population. METHODS: Consecutive subjects attending six primary care centers in Argentina were selected based on quota sampling and were interviewed using the EuroQol Group protocol for measurement and valuation of health studies. Initially, the respondents were randomly assigned a unique card set; however, to improve efficiency, the subjects were later randomly assigned to one of three fixed sets of EQ-5D states. Using the visual analog scale (VAS) and time-trade off (TTO) responses for these states, we estimated a valuation model using ordinary least squares regression clustered by respondent. Predicted values for EQ-5D health states are compared with published values for the United States. RESULTS: Six hundred eleven subjects were interviewed by 14 trained interviewers, rendering 6887 TTO and 6892 VAS responses. The model had an R(2) of 0.897 and 0.928 for TTO and VAS, respectively. The mean absolute difference between observed and predicted values was 0.039 for TTO and 0.020 for VAS, each showing a Lin's concordance coefficient more than 0.98. Argentine and US TTO-predicted values were highly correlated (Pearson's rho = 0.963), although the average absolute difference was clinically meaningful (0.06), rejecting the US values for nearly two-thirds of the states (62.8%). The Argentine population placed lower values on mild states and higher values on severe states. CONCLUSION: This study provides an Argentine value set that could be used locally or regionally, with meaningful and significant differences with that of the United States. Health policy in Latin America must incorporate local values for sovereignty and validity.

Childhood pneumococcal disease burden in Argentina.

OBJECTIVES: To understand the disease burden of pneumococcal disease (PD), a major cause of childhood morbidity and mortality in Argentina, and to draw a baseline against which the need for and effectiveness of vaccination with pneumococcal conjugate vaccines might be measured. METHODS: A Markov model was constructed to estimate incidence and mortality rates of PD-meningitis (MEN), bacteremia/septicemia (BACT), pneumonia (PNEU), acute otitis media (AOM)-among a hypothetical, birth cohort of 750,000 Argentine infants born in 2006-2015. A systematic review of the literature was performed to select and incorporate input parameters. Life years and costs in 2006 US$ were expressed as both undiscounted and discounted. RESULTS: The number of PD episodes estimated to occur over a 10-year period in the hypothetical birth cohort were: MEN, 225; BACT, 2841; PNEU, 2628; and AOM, 2,066,719. Chronic sequelae of MEN could be expected to cause neurological damage in 43 children and severe hearing issues in 28. Results indicate that there would be 78 PD-related deaths in the cohort (29% due to MEN; 54%, BACT; and 17%, PNEU). The undiscounted life-expectancy for individuals in the birth cohort was estimated to be 72.4 years (29.0 years discounted). Mean, undiscounted, lifetime costs attributed to PD for each child of the cohort totaled US$167 (US$151 discounted), imposing a total, cohort cost-burden of more than US$126 million (US$113 million discounted). CONCLUSIONS: The study shows that PD imposes a significant health and economic burden on the Argentine population. This information is essential for assessing the potential health and economic impact of introducing pneumococcal conjugate vaccine into the national immunization schedule.

OBJETIVOS: Analizar la carga que provoca la enfermedad neumocócica (EN), una importante causa de morbimortalidad infantil en Argentina y establecer una línea de base a partir de la cual se pueda medir la necesidad y la eficacia del uso de vacunas antineumocócicas conjugadas. MÉTODOS: Se elaboró un modelo de Markov para estimar las tasas de incidencia y mortalidad por meningitis (MEN), bacteremia/septicemia (BACT), neumonía (PNEU) y otitis media aguda (AOM) asociadas con la EN, en una cohorte hipotética de 750 000 niños nacidos en Argentina entre 2006 y 2015. Se realizó una revisión sistemática para seleccionar los parámetros de entrada y utilizarlos en el modelo. Los resultados se expresaron en años de vida y costos en dólares estadounidenses (US$), con descuento y sin descuento. RESULTADOS: Los episodios de EN que se estima ocurrirían en un período de 10 años en la cohorte hipotética serían 225 MEN, 2 841 BACT, 2 628 PNEU y 2 066 719 AOM. Las secuelas crónicas de las MEN podrían causar daños neurológicos en 43 niños y trastornos auditivos graves en 28. Estos resultados indican que en esta cohorte habría 78 muertes asociadas con la EN (29 por ciento por MEN, 54 por ciento por BACT y 17 por ciento por PNEU). La esperanza de vida sin descuento estimada para los niños de la cohorte fue de 72,4 años (con descuento de 29,9 años). Los costos promedio sin descuento atribuidos a la EN por cada niño de la cohorte durante toda la vida fueron de US$ 167 (con descuento de US$ 151), lo que provocaría un costo total para la cohorte de más de US$ 126 millones (con descuento de US$ 113 millones). CONCLUSIONES: Estos resultados demuestran que la EN impone una carga sanitaria y económica significativa a la población argentina. Esta información es esencial para evaluar el posible impacto sanitario y económico de la introducción de la vacuna conjugada antineumocócica en el programa nacional de vacunación.
