Abstract
Background:
As part of the Cochrane Linked Data project we are PICO (Population, Intervention, Comparison, Outcomes) annotating our systematic reviews (SR) of interventions. PICO is the structure generally used to formulate a SR question and the search strategy to retrieve studies to be included in the SR.
By PICO annotating our SRs we are enriching our content and data, using controlled vocabularies (e.g. SNOMED, WHO ATC/DDD, MeSH), and, by creating our own commonly used terms we are developing a Cochrane Vocabulary.
Since 2016 we have been developing an annotation tool set. We annotated SRs for the Neonatal Group, Pregnancy & Childbirth Group and Cochrane Child Health as part of a project funded by the Gates Foundation. In the last quarter of 2017 we started to work with other Cochrane Review Groups (CRG) to annotate SRs in other topic areas.
In the near future, these meta-data will be available via the PICO search widget on the Cochrane Library.
Objectives:
1) To annotate the PICO for all Cochrane Systematic Reviews of Interventions.
2) To demonstrate how the PICO search widget retrieves the annotated meta-data.
Methods:
We will focus our efforts on annotating the methods in each review published since January 2018. The Meta-data Specialists will provide training and support for CRGs in one-to-one meetings, documenting guidance and actively taking part in discussions on term selection. In cases where CRGs do not have the resources to take on the annotation task the Meta-data Specialists will annotate their reviews, and a member of the CRG with domain knowledge will provide a quality control check.
Results:
We will have two sets of results to present. The first set focuses on the annotation process e.g. the number of annotations completed, topics covered and the quality of those annotations across the four PICO elements.
The second set will show various sample interfaces of the PICO search widget, which is in development, and its implications for the Cochrane Library platform.
