Our Systematic Review Service can also assist you and your team with Scoping Reviews.
A scoping review is a relatively new approach to evidence synthesis and differs from systematic reviews in its purpose and aims. The purpose of a scoping review is to provide an overview of the available research evidence without producing a summary answer to a guide clinical decision-making.
Scoping reviews are a form of knowledge synthesis, which incorporate a range of study designs to comprehensively summarize and synthesize evidence with the aim of informing practice, programs, and policy and providing direction to future research priorities.
The general purpose for conducting scoping reviews is to identify and map the available evidence.

|Indications for Systematic Reviews|
|Uncover the international evidence|
|Confirm current practice/ address any variation/ identify new practices|
|Identify and inform areas for future research|
|Identify and investigate conflicting results|
|Produce statements to guide decision-making|
|Indications for Scoping Reviews|
|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 analyze knowledge gaps|

Systematic and scoping reviews aim to be comprehensive, transparent, reproducible, and unbiased – this is not typically the case with a traditional literature review. With clear and explicit methodology, the reader knows exactly how the authors of a study came to their conclusions, rather than relying on expert opinion or subjective selection that is usually found in a literature review.

|A priori review protocol||No||Yes||Yes|
|Registering protocol||No||Yes||Sometimes, but not accepted in PROSPERO|
|Searching for relevant literature||Not comprehensive, typically only include published literature||Comprehensive search to locate all relevant published and unpublished studies||Comprehensive search to locate all relevant published and unpublished studies|
|Deciding which studies include/exclude||Undefined; typically only include studies that support claims||Explicit description of what types of studies are to be included||Explicit description of what types of studies are to be included|
|Standardized data extraction forms||No||Yes||Yes|
