What this series of posts are about<\/h1>\n

This is the first in a series of blog posts detailing how to put together a literature search for a systematic review (SR). The Information Services Team in the Library are often asked for practical examples and texts to guide others through the process and I have not been able to find anything that brings things together in one place; all the information is scattered throughout books and journal articles. Plus they tend to be rather abstract and theoretical. Therefore, this will follow the process through a real-life example as I construct and run a search for STRIVE<\/a>. Thank you to the STRIVE team for permission to write this series of blogs about their research.<\/p>\n

About me<\/h1>\n

My name is Jane Falconer and I have been a medical librarian for 20 years. I lead the User Support & Information Services Team in the library and one of our services is to support researchers conducting systematic reviews. I have also worked with School research groups to construct searches for them, for example I ran the search for evidence behind the Lancet Planetary Health Commission Report<\/a>, and the systematic reviews behind the WHO Guidelines on Hepatitis B and C Testing<\/a>.<\/p>\n

Preparing to start a SR search<\/h1>\n

When I am asked to put together a search, I usually know nothing about the topic: I\u2019m a librarian, not a researcher. Therefore, I always have to spend a bit of time getting to understand the subject that is being reviewed. This is what this first post in the series deals with.<\/p>\n

The preparation is key in putting together a literature search. Spending some time at the beginning of the process agreeing in the group about what is and is not covered by the review saves a lot of time later on. It\u2019s impossible to put together an effective search if you don\u2019t know exactly what you\u2019re looking for. Over the years I have put together the questionnaire below which I run through with the research group. Having it written down means that I don\u2019t forget to ask something. Having it on a document means that I can also add to it as the project advances. I’ve added some comments about some of the questions beneath.<\/p>\n

About the project<\/h3>\n

Do you have a protocol\/proposal\/terms of reference?<\/strong>\u00a0It is best practice to publish a SR protocol. PRISMA have published a reporting tool for protocols<\/a> which can be registered on PROSPERO<\/a>. If an SR has been commissioned, the funders may have produced a protocol or some terms of reference.<\/span><\/p>\n

When do you need the search to be completed by?\u00a0<\/strong>Some funders set very tight deadlines and often researchers underestimate how long it will take to construct and run the search.<\/p>\n

Do the funders recommend you follow any particular methodological guidelines for their SRs?\u00a0<\/strong>Some funders specify that you follow guidelines such as PRISMA or Cochrane.<\/p>\n

If not, would you like to follow any recognised guidance?<\/strong><\/p>\n

Questions to be answered by the SR<\/h3>\n

Give me as much detail about the topic as you can.\u00a0<\/strong>This is important, particularly for me as I have no subject knowledge. I need to know exactly what the SR covers and what it does not. I often ask researchers for lists of terms, such as names of tests or types of equipment or drugs. It’s good to know what is not included. The more information I can gather the better.<\/p>\n

What are the inclusion and exclusion criteria?<\/strong> This is the criteria the screeners will use to decide if a paper is relevant to the review and often includes the following (not all of these categories need an answer):<\/p>\n

Age range of participants\u00a0<\/strong><\/p>\n

Date range<\/strong> Don’t choose an arbitrary date range, such as ‘last 10 years’. The date range should be meaningful to the topic so that anything published before then would not be relevant, eg anything published after a change in practice.<\/p>\n

Countries\/regions of interest<\/strong><\/p>\n

Study types<\/strong><\/p>\n

Language<\/strong><\/p>\n

Grey literature to be included?<\/strong><\/p>\n

Sources to be searched\u00a0<\/strong>This is the list of databases and other sources you will search. This is defined by the topic and also by the amount of time you have to do the review.<\/p>\n

Results<\/h3>\n

How are the results to be shared with the rest of the team?\u00a0<\/strong>I usually share the results in an EndNote file, but I have worked with teams who preferred the references in an Excel spreadsheet.<\/p>\n

Details of sample references<\/h3>\n

I always ask for references to other SRs on similar topics and lists of papers which the group already knows about which pass their inclusion and exclusion criteria. These are useful for building the initial search.<\/p>\n

After conversations with the team, here is the information I have about the STRIVE project so far.<\/p>\n

About the project<\/h3>\n

Do you have a protocol\/proposal\/terms of reference?<\/strong>\u00a0I have a project outline which has been written and agreed by all project members.<\/span><\/p>\n

When do you need the search to be completed by?\u00a0<\/strong>End of September 2017<\/p>\n

Do the funders recommend you follow any particular methodological guidelines for their SRs?\u00a0<\/strong>No.<\/p>\n

If not, would you like to follow any recognised guidance?\u00a0<\/strong>PRISMA<\/p>\n

Questions to be answered by the SR<\/h3>\n

Give me as much detail about the topic as you can.\u00a0<\/strong><\/p>\n

This will be a technical brief with an SR. Secondary output is for a book chapter.<\/p>\n

Topic: Effects of interventions for structural drivers of HIV in adolescents in sub-Saharan Africa<\/p>\n

Concepts:<\/p>\n

Adolescents, age 10-24, any study which includes this age range even if the study looks at a wider age range.<\/p>\n

Sub-Saharan Africa<\/p>\n

HIV\/AIDS<\/p>\n

Structural drivers. There\u2019s been a bit of discussion about what exactly this means. At this point we\u2019ve decided on the following:<\/p>\n

Alcohol drinking<\/p>\n

Transactional sex<\/p>\n

Gender inequality<\/p>\n

Intimate partner violence<\/p>\n

Poverty: interventions that offer economic empowerment thereby reducing engagement with sexual risk behaviours – for example cash transfer interventions (i.e. the image trial in South Africa)<\/p>\n

All of these topics are for heterosexual sex, so no LGBT sex\/gender issues<\/p>\n

What are the inclusion and exclusion criteria?<\/strong>\u00a0No biomedical or clinical interventions. No behavioural interventions (eg increase in condom use).<\/p>\n

Age range of participants\u00a0<\/strong>See concepts above<\/p>\n

Date range<\/strong>\u00a0Any date<\/p>\n

Countries\/regions of interest\u00a0<\/strong>Sub-Saharan Africa<\/p>\n

Study types\u00a0<\/strong>Experimental or observational. No qualitative studies<\/p>\n

Language\u00a0<\/strong>Any language<\/p>\n

Grey literature to be included?\u00a0<\/strong>No<\/p>\n

Sources to be searched\u00a0<\/strong><\/p>\n

Ovid Medline, Ovid Embase, Ovid Global Health, Ebsco Africa-Wide Information, Cochrane Library, Campbell Library, Web of Science, SCOPUS, ClinicalTrials.gov, HealthEvidence.org<\/p>\n

Results<\/h3>\n

How are the results to be shared with the rest of the team?\u00a0<\/strong>EndNote<\/p>\n
