 Abstract
 Writing health technology assessment (HTA)
 submissions is a challenging and rewarding
 area of medical writing, being part of the
 process of giving patients access to new
 medicines. Submission requirements differ
 between countries but all require clear
 communication of the new product’s value.
 This article looks at the medical writer’s role
 in UK and German submissions, but many of
 the points covered will be generalisable to
 other jurisdictions.

       ealth technology assessments (HTA) help
       inform payer decisions about what
medicines and other technologies to fund, and at
what price. These may be carried out by official
national bodies, such as England’s National
Institute for Health and Care Excellence (NICE),
France’s National Authority for Health (HAS),
and Germany’s Federal Joint Committee (G-
BA), or at local and regional levels. Medical
writers play an important role in the writing and
managing of dossiers submitted by manu-
facturers to the decision-making bodies. This
article outlines the medical writer’s role in HTA
submissions (also known as reimbursement
submissions) and examines how we can add
value in the quest for a successful appraisal, one
which culminates in patient access to novel
medicines and reimbursement at a satisfactory
price for both the manufacturer and the health
system.
    Writing HTA submissions is a challenging
and rewarding role that sits somewhere between

    Furthermore, it is important to define the
population for which the new technology should
be funded, and to provide an estimate of
population size. Linked to this, there must be a
clear description of the current treatment
pathway based on national clinical guidelines and
protocols, and of where in the pathway the
technology will sit and what (if any) current
treatments it is expected to displace. These
treatments are known as the comparators. Unlike
clinical trials, where there is typically a single
comparator, payers compare new technologies
against all current treatments.

presents the pivotal clinical trial. This section
