and outcomes (at a national, regional, or hospital level) with
device purchasing decisions, according to ISPOR - The
Professional Society for Health Economics and Outcomes
Research. The group published its findings in Value in Health.
" Assessing the value of medical devices is a key element in
making adoption and coverage decisions, but there are challenges
in applying value frameworks to them, " says author
Simon Eggington, MSc, Medtronic International Trading
Sarl, Tolochenaz, Switzerland. " Medical devices have unique
characteristics, such as frequent device iterations and user
learning curves, which make it difficult to generalize outcomes
- and therefore value - to the broader patient
population.
" Additionally, " he says, " many device types exist, each potentially
requiring different assessment criteria, and stakeholders
may view the value of any technology differently
based on their specific needs. As a result, while there is a
vast reservoir of information and guidance on HTA, there
remains a knowledge gap as to whether nonpayer, non-HTA
stakeholders, such as hospital procurement, use the available
HTA reports and conclusions in their assessment of
medical devices. "
In an effort to fill this gap, members of the ISPOR Medical
Devices and Diagnostics Special Interest Group, in collaboration
with the Special Interest Group leadership team,
conducted a systematic literature review to identify relevant
studies and summarize the current evidence base for the criteria
used for procurement of medical devices.
Overall, however, the group found minimal evidence
regarding the use of HTA in device purchasing, making
it problematic to draw firm conclusions about the impact
of HTA on procurement, and what little evidence exists is
incomplete, regardless of the level or geography at which
the HTA and procurement occurs.
According to ISPOR, the application of HTA (and its im®

pact on treatment decisions) varies widely in different geographies,
complicating the process of making generalizations.
The use of " mini " or hospital-level HTA appears to be growing,
suggesting a shift from " classic " HTA to local evaluations,
which aims to directly inform procurement decisions.
Nevertheless, most of the hospital-level HTA studies reviewed
also drew on national-level HTA and published systematic
reviews of evidence to inform their conclusions, indicating a
continued need for national or regional assessments.
" Further research is needed to better understand the relationship
between HTA and procurement, and to identify
strategies to bring the two areas closer together and encourage
broader and more systemic evidence-based decision making, "
says Eggington.
