The United Kingdom spends approximately GBP4.2 billion (USD5.6 billion; EUR4.7 billion) each year on medical devices, but healthcare providers receive little health technology assessment (HTA) guidance on cost-effective device procurement. Our objective was to assess the availability of HTA guidance for medical technologies and to identify key challenges related to the economic assessment of these technologies.

National Institute for Health and Care Excellence technology appraisal (TA) and Medical Technologies Evaluation Programme (MTEP) appraisals published online between November 2009 and October 2020 were identified. The “case for adoption” recommendation, type of devices, and critiques of economic analyses for each MTEP appraisal were extracted and categorized.

In comparison to 415 publicly available TAs for pharmaceuticals, only 45 medical technologies have been appraised through the MTEP. MTEP-submitted technologies can be categorized into diagnostic (7), monitoring (3), prophylaxis (5), therapeutic (28), and other (2). Furthermore, 11 were implants, seven were used by patients, and 27 had provider interaction. Major points of MTEP criticism were a failure to model cost consequences, training costs, and organizational impact. There was also the barrier of transferring costs across budgeting divisions.

In comparison to HTA guidance for pharmaceuticals, there is a dearth of medical device guidance. Therapeutic and implantable devices appear to be disproportionately overrepresented in the MTEP process. This may be because their appraisal is most akin to pharmaceuticals, for which HTA processes are well established. To encourage more HTAs of medical devices, HTA guidance should elaborate on issues specifically related to medical devices.
