Research

A range of support is available.  To ensure mutual understanding, these are the first steps to work through.

• Do you need a systematic search or are you just looking for some references on a topic?  If you are OK for a librarian to search and select some references to forward to you without providing any documentation on the process, request a general literature search.
• If you are studying at university and a requirement of your course is to complete a search strategy yourself, your university librarians should be able to assist.  Limited guidance will be provided from this library. 
• More assistance is available if your research is endorsed and supported by the health service.

Need more than that?

• Formulate your initial question - it's not all PICO - there are many question frameworks described in a paper on formulating questions that may work better if you have questions on topics other than interventions - BeHEMoTH, CHIPS, CoCoPop, ECLIPSE, SPICE, SPIDER and more
• Request a scoping search - either a formalised, PRISMA for Scoping Reviews level search that requires extensive documentation, or a more general review of the literature to get a picture of the volume and scope of the literature on a topic.
• Reformulate your question using the question framework chosen 
• Decide upon the type of study you want to do (taking into consideration the reporting requirements for different study designs)
• Consider the level of search support and documentation you will require for your study design.

How systematic is your review?  This is an important question to consider upfront. See this paper:

• The most rigorous design is the systematic review which may use meta-analysis.  They are typically done by a review group (not an individual), they are very time consuming and typically take many months to complete.  Extensive documentation is required in line with reporting guidelines for the review type (PRISMA-S: an extension to the PRISMA Statement for Reporting Literature Searches in Systematic Reviews - January 2021).  Librarians have authorship as they write the search strategy paragraph in the article and the article's supplementary materials where complete search strategies and results are documented for every source searched.  They manage the references in an EndNote Library and de-duplicate references found from multiple sources.
• Other variants of review may be better suited to some questions or practical realities and may have simplified documentation requirements and fewer steps in the review process (examples:  a narrative review,   a systematic narrative review,  a systematic literature review and narrative synthesis,  a rapid review,  a systematic review of systematic literature reviews,  a scoping review,  a state of the art review,  an umbrella review).  If extensive documentation and writing is not required from a librarian, acknowledgment of librarian input in the published paper is required.
