Recently, a search filter was published in the Health Information and Libraries Journal by Lynda Ayiku et al of NICE that attempts to locate any articles that are about UK research, populations or practice in Medline, and exclude others.

The search filter is validated, meaning it has been tested against a gold standard set of references to make sure it works. The full search filter was designed for the Ovid version of Medline, but unfortunately does not work properly in the HDAS interface used by the NHS. However, there is a simplified version available, which we have adapted for use in the HDAS interface, and this can be copied and pasted into the search box on HDAS, and then combined with your subject search (uisng ‘and’) to filter your search to UK articles only.
