Definiciones
Generalizability
Whether the results from a given study apply to other settings
Transferability
The extent to which the results from a given study can be
adapted to apply to other settings.
Por que es un tema relevante?
• No hay recursos suficientes para hacer todos los estudios
en todos los lugares
• Frecuentemente los tomadores de decisión necesitan
adaptar o interpretar datos de otras jurisdicciones/países
• Los estudios presentados por la industria para solicitar
cobertura suelen incluir datos y/o modelos provenientes
de otros países
Hay varios factores que difieren entre los países y
que es esperable que impacten en los resultados
•
•
•
•
Demografía y epidemiología de la enfermedad
Precios relativos
Práctica clínica / tasas de uso
Distribución y disponibilidad de los recursos
sanitarios
• Incentivos a profesionales / instituciones
• Utilidades de los estados de salud
Los decisores sanitarios están utilizando documentos de evaluación
de tecnologías sanitarias de otros países

Al utilizar reportes de otros países la
información que consideraron más
útil fue la información sobre:
•Descripción de la tecnología
•Seguridad
•Eficacia y Efectividad
Les resultó menos útil y aplicable la
información sobre:
•Implicancias éticas y legales
•Impacto presupuestario
•Evaluación económica
•Aspectos organizacionales

Researchers – use of HTA from other jurisdictions
Researchers (HTA “doers”) reported using HTA reports from other
jurisdictions as an input/source when elaborating local HTA reports in 64%
of the situations

When using reports from other
jurisdictions they found more

Researchers – “adaptation” of HTA reports from other
jurisdictions
33% of the researchers reported having adapted an HTA
report to the local setting.
In 75% of the cases the reports adapted came from other
regions and just 25% where reports from other Latin American
countries.

Use of International Resources
• Websites frequently consulted; NICE, CRD(York),
CADTH, SMC, PBAC
• Very little use of transferability checklists (eg
Eunethta checklist)
• Very little use of studies undertaken in other
countries in the region
HEE methodological guidelines in Latin America
Countries with HEE
guidelines
Brazil, Colombia,
Cuba and Mexico
MERCOSUR:
Argentina, Brazil,
Paraguay and
Uruguay
Grupo Andino:
Bolivia, Chile,
Colombia, Ecuador,
Peru, Venezuela
Most of these guidelines were produced or are being
sponsored by the public government, suggesting their
interest in going in that direction regarding decision making
of new and existing technologies for reimbursement and
financing purposes.
A. Pichon-Riviere Institute for Clinical Effectiveness and Health Policy, Argentina (www.iecs.org.ar)
What these guidelines say about the use of data, models and information from
other jurisdictions?
MEXICO: If information from international sources or from clinical trials from
different contexts is used, appropriate adjustments must be considered in relation
to differences in resource use. Data should be validated and adjusted in relation to
local practice, besides having into consideration the differences in resource use
between routine practice and that developed for research purposes.
BRAZIL: QALYs. It is preferable that local utilities are used. If these are not available
can be used international sources.
CHILE - Modeling section: If the model was developed and validated abroad (or in
another context), its use for national reality must be justified and the model should
be calibrated with national data
CHILE – Costs section: When data on cost of resources is not available at the local
level can be considered ultimately using international evidence. In these cases must
include the (descriptive and quantitative) analysis regarding the generalizability
and transferability potential. In all cases, the choice of methodologies, and
assumptions must be clearly justified.

Conclusion
In Latin America is commonplace to deal with the issue of
transferring analysis or data from other jurisdictions
The use and adaptation of HTAs from other jurisdictions can be a
valuable tool to overcome the scarcity of local information and the
lack of time and resources to generate evidence in the short term.
As the use of economic evaluations to inform reimbursement and
coverage decisions increases in middle income countries, it will be
increasingly important to ensure improved practices in evaluating
and conducting transferability of foreign data. Inadequacies in
dealing with transferability issues may lead to inappropriate
coverage decisions and the inefficient use of healthcare resources.
In the short and medium term:
•Define/Agree on methodologies to rigorously assess the degree of
transferability
• Invest in local data generation for those categories of data normally
considered to have low transferability, such as unit costs, health state
preference values and epidemiological data.
•As the number of HTA organizations in LA increases, they could
collaborate more fully within their region, since the transferability of
economic evaluations within the region is likely to be greater than
that between regions. (eg multi country economic evaluations)

General section about transferability: responses from HTA “users” and
“doers”
All respondents consider that using HTA reports from other jurisdictions is
potentially very useful. This potential was considered to be higher for HTA
reports from Latin America.
They consider it useful to:
•Improve the decision making process
•Fewer resources needed
•Obtain results faster
•Avoid duplication of work
Main barriers than limit the transferability of
HTA reports:
For HTA reports from Latin America
• Low quantity of HTA reports available
• Lack of guidelines/methods on how to adapt HTA reports
• Poor methodological quality
• Lack of transparency in the HTA reports published
Barriers for transferability: Poor methodological quality
For HTA reports from other regions
• Differences in health care costs
• Different epidemiological contexts
• Different health care systems
