Kleijnen Systematic Reviews Ltd is a "Centre of Excellence" for Technology Assessment Reviews (TARs), appointed by the National Institute for Health Research (NIHR).

TARs provide a reliable and rigorous evidence assessment of the benefits, harms and costs of particular healthcare treatments for those who plan, provide or receive care in the NHS.

TARs are commissioned to meet the urgent needs of national NHS decision-making bodies and policy customers, such as the National Institute for Health and Care Excellence (NICE). TARs are most commonly produced to inform NICE Appraisal Committee guidance on the use of new and existing medicines, treatments and procedures within the NHS in England and Wales.
