If you follow our blog, you’ll know that we care passionately about promoting the uptake of evidence and research by policymakers and practitioners. It’s easy to be complacent and assume that when public money is at stake, decisions are made on the basis of evaluations and reviews. Unfortunately, this is still not always the case.
The current evidence-based policy agenda in the UK encompasses initiatives such as the What Works network, the Local Government Knowledge Navigators and independent organisations such as the Alliance for Useful Evidence. They are working on fostering demand for evidence, as well as linking up academics with those in the public sector to ensure that the research community is responsive to the needs of those making decisions and designing/delivering services.
A recent article in Health Information and Libraries Journal highlights another challenge in evidence-based policy however. A mapping exercise has found that literature reviews often ignore specialist databases, in favour of the large, well-known databases produced by major commercial publishers. Within the health and social care field (the focus of the article), literature reviews tend to use databases such as Medline, Embase and Cinahl – and overlook independent UK-produced databases, even when they are more relevant to the research question.
Why does it matter?
Research has shown that how (and why) databases are chosen for literature searching can “dramatically influence the research upon which reviews, and, in particular, systematic review, rely upon to create their evidence base”.
To generate useful evidence for the UK context (relating to UK policy issues or populations), researchers need to understand the most appropriate database to search – but unfortunately our own experience of looking at the detail of methodologies in evidence reviews, suggests that in many cases the only databases searched are those produced by American or international publishers.
Grey literature is a valuable source in evidence reviews – and again this is often overlooked in the major databases which tend to focus only on peer-reviewed journal content. A recent Australian report ‘Where is the evidence?‘ argued that grey literature is a key part of the evidence base and is valuable for public policy, because it addresses the perspectives of different stakeholder groups, tracks changes in policy and implementation, and supports knowledge exchange between sectors (academic, government and third sector).
Another benefit of UK-produced databases is that they will make use of UK terminology in abstracts and keywords.
Social Policy and Practice – a unique resource
At this point I should declare a vested interest – The Knowledge Exchange is a member of a UK consortium which produces the Social Policy and Practice (SPP) database. The SPP database was created in 2005 after five UK organisations, each with a library focused on sharing knowledge in community health and social care, agreed to merge their individual content in order to make it available to the widest possible audience.
The current members of the SPP consortium – the National Children’s Bureau, the Idox Knowledge Exchange, the Centre for Policy on Ageing and the Social Care Institute for Excellence – have just been joined by the National Society for the Prevention of Cruelty to Children. Inclusion of the NSPCC’s bibliographic data greatly enhances the coverage of child protection research in the database. SPP has been identified by NICE, the National Institute for Health and Care Excellence, as a key resource for those involved in research into health and social care.
We want the UK research community to understand what SPP offers, and to use it when undertaking literature reviews or evidence searches. This process of awareness raising should start with students – librarians in universities and the UK doctoral training centres have a key role in this as it ties in with the development of information literacy and critical appraisal skills. Ignoring specialist sources such as SPP risks introducing bias – at a time when initiatives are attempting to embed research and analytics in local government and the wider public sector.
Information on the coverage of Social Policy and Practice is available here and the distributor Ovid is offering a free 30-day trial.
