Background
Health inequities are unfair, systematic disparities in health outcomes between population subgroups, arising from the social conditions in which people live, and they are therefore associated with people’s social, economic or personal characteristics. Health inequities are closely related to (and reflect) issues of equality, diversity and inclusion, as they are most often experienced by marginalised, at-risk and/or socially excluded people, members of inclusion health groups and/or those with protected characteristics. People in equity-related subgroups may be identified in terms of a range of personal characteristics, reflecting multiple dimensions of health inequity, including (but not limited to): age; sex; gender; sexual identity; race, ethnicity and ancestry, socio-economic status; level of education; disability; and/or location (country).
About this guidance
We have primarily developed this guidance and suite of tools to provide a flexible template for promoting routine consideration and reporting of methods and processes for incorporating health equity perspectives and/or investigating health equity issues in protocols and full reviews or maps conducted by the UK National Institute of Health Research (NIHR) Policy Research Programme (PRP) Reviews Facility ('NIHR PRP Reviews Facility'). It aims to draw together several relevant strands of methods guidance and tools for systematic reviews (see 'Signposted wider sources of guidance and tools', below).
The guidance is intended for users with advanced expertise in systematic review and evidence synthesis methods. To apply this guidance, users will need to be closely familiar with details of the wider sources of methods guidance and tools it draws together and signposts, and their implications for conducting reviews (see 'Signposted wider sources of guidance and tools', below).
The current version of this guidance and tools is Version 1.0 (October 2024). This version is currently undergoing its first phase of piloting (see below for details).
These materials will evolve as we continue to develop them, and updated versions will be made available on this webpage. The next steps are that we plan: (1) to iteratively develop and (pilot) test this guidance and suite of tools using selected NIHR PRP Reviews Facility (and other) evidence synthesis projects; and (2) to (continue to) collaborate with other interested researchers, groups and networks, to formally develop the methods guidance and tools to make them broadly applicable for wider use by the international systematic reviews and evidence synthesis communities.
