Definition of HTA
HTA is a “…multidisciplinary process that summarises information
about the medical, social, economic and ethical issues
related to the use of a health technology in a systematic, transparent,
unbiased, robust manner…”
(EUnetHTA n.d.)
What are the apples in HTA? What are the oranges?

Apples and oranges in HTA of palliative care
• The variety of assessed aspects
•
Example : Hospitalization, „good death“,
continuity of care
• The assessment results
•

One decision
Example: Effectiveness: effect size for several outcome parameters like
mortality, morbidity, quality of life etc. Ethics: several identified issues like
the importance of patient autonomy in palliative care
• Context as modifying factor and factor of uncertainty
•
Example: socio-cultural factors like religion
• Values, preferences and understanding of all relevant stakeholders, including
decision-makers

Methods
Information sources and search
Web of Science; Medline, PsycINFO and the non-medical databases Econlit,
ASSIA, International Bibliography of the Social Sciences, Sociological abstracts
were searched from January 2004 up to April 2014.
Inclusion criteria
• Methods including multiple, quantitative or qualitative aspects
• Should include connective elements to merge criteria/ aggregate criteria/
address interdependencies between criteria
• Address aspects of the data extraction framework about integration
Exclusion criteria
• Simply side-by-side assessment, frameworks that only provide decision
criteria

Results of search strategy
3848 Records identified after dublicates removed.
Records excluded (Different topic e.g. basic research)
2054 records assigned to the approach that was applied
30 approaches included in the synthesis.

30 approaches:
MCDA approaches
Analytic approaches
Preference elicitation approaches
Consensus methods
Do they address…
Data extraction

Evidence issues e.g.
effect sizes, context,
uncertainty
Judgment and
evaluation issues e.g.
values and preferences
Decision issues e.g.
comparissons to other
technologies

Conclusion
• The results of this review provide guidance on suitable
combinations of different methods.
• All identified techniques can be used in an additive manner
as they all cover different aspects of integration.
