Scoping Review
Course Number: HE450
Subject: Health Sciences
What is a scoping review?
A scoping review is a type of evidence synthesis that uses systematic and transparent methods to identify and retrieve all the relevant research on a specific topic. Scoping reviews do not aim to provide the answer to a particular question, but instead they aim to provide an overview or map of the evidence.
According to Munn, et al (2018, p.2) there are several reasons why a scoping review might be conducted:
- To identify the types of available evidence in a given field,
- To clarify key concepts/ definitions in the literature,
- To examine how research is conducted on a certain topic or field,
- To identify key characteristics or factors related to a concept,
- As a precursor to a systematic review,
- To identify and analyse knowledge gaps.
General Guidelines
- Cannot be completed by a single person:
- Multiple people are needed to reduce bias during screening and data extraction
- Require a substantial time commitment:
- Scoping reviews take an average of 9-12 months.
- Must use transparent and reproducible methods:
- Use established methodologies,
- Make your full search strategy for at least one database available.
Key Stages in a scoping review
- Explore the topic with some preliminary searches, and check that a major review on the topic doesn’t already exist,
- Develop clear research questions,
- Write a protocol that outlines inclusion/exclusion criteria for screening and a draft data extraction table,
- Build a systematic search strategy in your main database, test and refine it, then translate it for your other databases,
- Train people who will be screening to ensure consistency,
- Screen title & abstract,
- Obtain full text articles and add to Covidence,
- Screen full text,
- Complete data extraction & analysis,
- Write up and submit for publication.

Author Guidelines
- Evidence synthesis papers often have multiple authors. The International Committee of Medical Journal Editors (ICMJE) provides helpful guidelines on defining the role of authors and contributors.
- One key point is that all authors must have “final approval of the version to be published”. Do not submit a work for publication without first sharing the final version of the paper and checking that all the people listed as authors wish to be included.
