Hidlau Chwilio

Beth yw hidlyddion chwilio?
Ble alla i ddod o hyd i hidlyddion chwilio?

"Mae hidlyddion chwilio yn gasgliadau o dermau chwilio sydd wedi'u cynllunio i ddod o hyd i ddetholiadau o gofnodion. Gellir cynllunio hidlyddion chwilio i ddod o hyd i gofnodion ymchwil gan ddefnyddio cynllun astudio penodol neu ar sail pwnc neu ryw agwedd arall ar y cwestiwn ymchwil.

Gall hidlyddion fod â ffocws penodol iawn neu gallant fod ar lefel uchel. Gellir cynllunio hidlyddion chwilio i uchafu sensitifrwydd (neu adalw) neu i uchafu manylder (a lleihau nifer y cofnodion amherthnasol y bydd angen asesu eu perthnasedd)."

What is the ISSG filter resource?

BMJ Study design search filters Our systematic review and RCT search strategies have been designed and tested in-house by BMJ Evidence Centre information specialists. Our observational study and adverse effects filters were also designed in-house. Strategies have been designed to retrieve studies most likely to meet our methodological criteria. In designing our strategies we have been aware of, and at times have drawn on, search strategy work conducted by others.

The InterTASC Information Specialists' Sub-Group (ISSG) Search filter resource The InterTASC Information Specialists' Sub-Group (ISSG) is the group of information professionals supporting research groups within England and Scotland providing technology assessments to the National Institute for Health and Care Excellence (NICE) and other associated Information Specialists. The InterTASC Information Specialists' Sub-Group Search Filter Resource is a collaborative venture to identify, assess and test search filters designed to retrieve research by study design or focus. The Search Filters Resource aims to provide easy access to published and unpublished search filters. It also provides information and guidance on how to critically appraise search filters, study design filters in progress and information on the development and use of search filters. Inclusion of a search filter is not an endorsement of its validity or a recommendation.
SIGN Search filters The search filters used by SIGN (Scottish Intercollegiate Guidelines Network) are developed in-house or are created by other research organisations and adapted to meet SIGN information needs. SIGN's filters may provide less sensitive searches than used by other systematic reviewers such as The Cochrane Collaboration, but enable the retrieval of medical studies that are most likely to match SIGN's methodological criteria. SIGN has devised suitable strategies for running each search filter in Ovid implementations of Medline, Embase and CINAHL along with other more specialised databases.
