NIHR-HTA Database


The NIHR HTA database provides free access to bibliographic information about ongoing and published health technology assessments commissioned or undertaken by members of INAHTA and other HTA organizations from around the world. It is funded by the UK National Institute for Health Research (NIHR) and is currently produced by the Centre for Reviews and Dissemination (CRD).

The HTA database is a valuable resource for locating literature and information not freely available from any other single source. The database provides a comprehensive listing of over 15,000 in progress and published health technology assessments from around the world. It was established in 1998 by combining health technology assessment records identified by CRD with INAHTA’s embryonic set of bibliographic details for HTA reports produced by their members. This means the records go back to 1989.

There are two record types on the HTA database, Projects in-progress, which are updated to Published projects once the full report becomes available. Contributing organizations complete a proforma with project and/or publication information and submit it to CRD, who then enter the details on the HTA database. Where funding allows, CRD staff also identify new projects and publications by searching HTA websites.

A new Canadian search interface for the Health Technology Assessment (HTA) database was launched in January 2015. The new interface is the result of collaboration between CRD and the Pan-Canadian HTA Collaborative Working Group for a Canadian HTA Repository. The Canadian search interface can be found at

This mutually beneficial collaboration involved Canadian agencies piloting a new ‘client administration system’ developed for contributors to the HTA database. This system will now be rolled out across the international HTA community, starting with INAHTA members, to facilitate direct uploading of records to the HTA database.

Selected records on the HTA database are also available in Spanish, produced by AETS at the Instituto de Salud Carlos III in Madrid.

Inclusion criteria

Many different types of research are included in the HTA database, e.g., ongoing and completed health technology assessments based on systematic reviews, trials, non-experimental studies, and economic evaluations. The HTA database does not use quality inclusion criteria to select records for the database and published reports are not critically appraised. However, all records in the database are publications and projects from INAHTA members and other internationally recognized HTA organizations.


CRD and INAHTA would like to extend their gratitude to all HTA colleagues who contribute and keep the information in the database up-to-date.
