Plugging knowledge gaps to demonstrate the benefits of new medicines
Due to the finite budgets available to national health systems, doctors are often restricted in the treatments they can prescribe. Decisions must be made to prioritise those treatments that
are both effective and cost-effective. However, sometimes there is a lack of
information available to support these decisions. Consensus techniques, such as
the Delphi method, are structured processes that can be used to provide
unbiased evidence from healthcare experts. The use of such evidence-generating
methods is aimed at reaching consensus where there are knowledge gaps in either
the published scientific literature or where there are variations in how patients
are treated. Answers to such questions may be particularly important for health
technology appraisals (HTA)s, which provide guidance on whether new medicines
should be made available for prescribing.
Hayward Medical Communications recently presented a poster,
titled The use of consensus techniques to
inform health technology appraisals, at the 19th Annual European
Conference of the International Society for Pharmacoeconomics and Outcomes
Research in Vienna, Austria. The study aimed determine whether consensus evidence
gathering techniques were used to inform guidance on medicines undergoing
health technology appraisals. The use of consensus techniques was determined by
searching appraisal documents and web sites of UK-based HTA bodies. The use of
consensus techniques was reported in nine technology appraisals from the three different
UK HTA bodies, with numbers increasing between 2013 and 2015. Use of these
techniques was primarily during assessment of medicines for rare illnesses, possibly reflecting a lack of
evidence in such therapy areas.
Presenting author, James Davies, commented, ‘It’s
important to understand if alternative information gathering techniques satisfy
the evidence criteria set by HTA bodies, considering the increasing use of
medicines for rare conditions, where evidence from conventional sources can be
limited’.
