What Is A Scoping Review – Meaning And Examples

Published by at December 28th, 2023 , Revised On October 30, 2025

A scoping review is a literature review that aims to provide a preliminary assessment of the size and scope of the available research literature.

It offers a clear overview of a field’s breadth (and sometimes depth) without necessarily delving into the details of individual study quality or aggregating results.

Think of it as a way to map the existing literature on a topic to identify gaps, trends, and the volume of available research.

Scoping Review Example

 

Title: Telemedicine in the Management of Chronic Diseases: A Scoping Review

Objective: To provide an overview of the current state of research on the application and effectiveness of telemedicine for managing chronic diseases.

Methods:

  • Search Strategy: Databases searched include PubMed, EMBASE, and Google Scholar from January 2000 to January 2023.
  • Inclusion Criteria: Articles that discussed telemedicine applications, platforms, and outcomes in the context of chronic disease management.
  • Exclusion Criteria: Studies that focused on acute conditions, reviews, and non-English articles.

Results:

Total Identified Records: 1,200

Total Included Records: 150

Types of Chronic Diseases Studied:

  • Diabetes (40 studies)
  • Hypertension (30 studies)
  • Chronic Obstructive Pulmonary Disease (20 studies)
  • Others (60 studies)

Types of Telemedicine Tools Used:

  • Video Consultations (80 studies)
  • Remote Monitoring Devices (50 studies)
  • Mobile Health Apps (20 studies)

Reported Outcomes:

  • Improved medication adherence (60 studies)
  • Decreased hospital admissions (40 studies)
  • Enhanced patient-provider communication (50 studies)

Discussion:
General Observations: The majority of the studies reported positive outcomes associated with the use of telemedicine for managing chronic diseases. Diabetes and hypertension were the most commonly studied conditions.

Knowledge Gaps: Few studies addressed the cost-effectiveness of telemedicine tools. There was also limited research on patient satisfaction and the integration of telemedicine into primary care workflows.

Conclusion: Telemedicine appears promising in the management of chronic diseases, especially diabetes and hypertension. Future research should address the identified knowledge gaps and explore other chronic conditions not yet studied extensively.

 

What are the Key Characteristics of a Scoping Review?

Here are the characteristics of a scoping review.

  • Scoping reviews serve as an initial exploration of the available literature on a specific topic, especially when researchers are in the early stages of understanding that subject.
  • Scoping reviews differ from systematic reviews in their approach to analysing the available literature, which, through a meticulous examination of study quality, aims to aggregate or synthesise results.
  • Scoping reviews lack a quality appraisal for the studies they encompass. This starkly contrasts with systematic reviews, which thoroughly assess the quality and reliability of included studies.
  • Scoping reviews are recognised for their inclusive approach to literature selection, which often encompasses diverse study designs, methodologies, and research approaches. By casting such a wide net, scoping reviews ensure they capture a research topic’s multifaceted nature.

 

Why Conduct a Scoping Review?

There are several reasons a researcher might choose to conduct a scoping review:

  • To understand how much research exists on a topic, evaluate sources and determine which study types dominate the field.
  • Before investing the time and resources into a full systematic review, a scoping review can help determine its worth.
  • By understanding what is already out there, researchers can identify gaps in the literature and shape the direction of their primary research.
  • Policymakers, practitioners, and stakeholders can utilise scoping reviews to understand a topic’s research landscape quickly.

For conducting and analysing health and social science topics, the JBI scoping review method developed by the Joanna Briggs Institute is used. This method offers robust standards for conducting and reporting high-quality scoping reviews.
 

How to Write a Scoping Review?

Writing a scoping review requires a clear understanding of the methodology, which involves the systematic search, selection, and charting of literature to clarify topics, identify knowledge gaps, and inform future research or policy direction across broad subject areas.

Here are the steps typically involved in conducting a scoping review:
 

Step 1: Identifying the Research Question

This is often broader in nature for scoping reviews than for systematic reviews. For example, “What interventions have been studied for the treatment of X condition?” rather than “Is treatment A more effective than treatment B for condition X?” This will also help you to develop an effective research strategy.
 

Step 2: Defining Inclusion and Exclusion Criteria

Clearly define which studies will be included or excluded based on specific factors such as publication date, study type, population, and outcomes.
 

Step 3: Searching for Relevant Studies

  • Identify relevant databases (e.g, PubMed, Scopus, Web of Science).
  • Develop a search strategy using keywords and Boolean operators.
  • Perform the search and document the results.

 

Step 4: Selecting Studies

  • Review titles and abstracts to exclude irrelevant studies.
  • Obtain and review full-text articles to determine their final inclusion.

 

Step 5: Charting the Data

This involves extracting relevant information from the included studies and managing sources. 

Create a data charting form to capture information on study design, population, intervention, outcomes, and key findings.
 

Step 6: Collating, Summarising, and Reporting the Results

  • Present an overview of the number and types of studies included.
  • Describe the main findings and any patterns or trends.
  • Create tables or figures to represent the data visually.

 

Step 7: Consultation (Optional but Recommended)

Engage stakeholders (e.g., experts, patients, policymakers) to provide insights or feedback on the preliminary results. 

This can add depth and relevance to the findings.
 

Step 8: Discussion and Implications

Discuss the main findings, their implications, and any potential gaps in the literature. This can guide future research efforts.
 

Step 9: Limitations

Acknowledge any limitations of your scoping review, such as publication bias or the exclusion of non-English articles.
 

Step 10: Conclusion

Sum up the key points from your review, the current state of the literature on the topic, and potential directions for future research.
 

Note:

Follow all the scoping review guidelines, which recommend structured approaches for searching, selecting, and presenting evidence. This will ensure transparency and rigour.

Moreover, it will help you, as a researcher, produce comprehensive and reproducible literature mapping. 

For this purpose, scoping review templates are also available on the market that outline sections from objectives to methodology and analysis, supporting authors in systematically organising and reporting their literature mapping process.

 

What is Scoping vs. Narrative vs. Systematic Review?

 

Feature Scoping Review Narrative Review Systematic Review
Purpose A scoping review maps the breadth of existing literature. Its main goal is to identify key concepts, types of evidence, and research gaps without detailed quality appraisal. A narrative review provides a descriptive summary of existing knowledge and theoretical insights but lacks a systematic methodology. A systematic review critically assesses and synthesises research findings using predefined criteria to ensure evidence quality and minimise bias.
Approach Exploratory and broad, focusing on mapping rather than evaluating evidence. Descriptive and flexible, guided by the author’s perspective and interpretation. Rigorous, protocol-driven, and focused on answering a specific research question.
Outcome Identifies research trends, themes, and gaps for future study. Provides contextual and theoretical understanding of a topic. Generates evidence-based, reproducible, and transparent conclusions.

 

Examples of Scoping Reviews

To illustrate the utility and diversity of scoping reviews, let us delve into some real-world examples:
 

1. Mental health apps

A researcher might conduct a scoping review to explore the types and features of mental health apps available in app stores, understanding their functionalities, target audiences, and underlying psychological theories.
 

2. Educational methods in virtual reality

Given the rapid advancements in VR technology, a scoping review may be conducted to assess how VR is being utilised in educational settings, the subjects to which it is being applied, and the outcomes of such interventions.
 

3. Sustainability practices in small businesses

As sustainability becomes a hot topic, researchers may want to understand how small businesses are implementing sustainable practices, the challenges they face, and the range of reported outcomes.
 

4. Dietary trends and nutritional health

To understand the landscape of evolving dietary trends, a scoping review could be conducted to identify popular diets, their nutritional implications, and their long-term health impact.
 

Frequently Asked Questions

A scoping review is a type of research synthesis that aims to map the key concepts, types of evidence, and gaps in a specific research area. Unlike systematic reviews, which assess the quality and synthesise findings of studies, scoping reviews provide an overview of the existing literature regardless of study quality.

A scoping review maps key concepts, evidence types, and research gaps without appraising study quality. It provides an overview of existing literature in a field. A systematic review, on the other hand, rigorously assesses and synthesises findings from selected studies based on predefined criteria, ensuring a high level of evidence quality.

Yes, a scoping review is a research methodology used to provide a preliminary assessment of the size and scope of available research literature. It maps key concepts, sources, and gaps without necessarily delving deep into quality appraisal. The process is systematic, ensuring a broad overview of the topic in question.

A scoping review maps the breadth of literature, identifying key concepts and research gaps without detailed quality appraisal. A narrative review offers a descriptive summary of topics, often lacking systematic methods. A systematic review rigorously assesses and synthesises research findings based on predefined criteria, ensuring evidence quality and reducing bias.

No, a scoping review and meta-analysis are distinct. A scoping review maps the literature, identifying key concepts and gaps, without a detailed quality appraisal. A meta-analysis is a statistical method used in systematic reviews to combine and analyse quantitative results from multiple studies to produce a single summary effect size.

A scoping review can include both qualitative and quantitative studies; it depends on the researcher’s objective. The primary purpose of the review is to explore the breadth and depth of evidence on a topic, making it more inclusive and exploratory.

Yes, a scoping review can be peer-reviewed to ensure the quality, accuracy, and transparency of the research process before submission.
However, note that the review itself does not inherently involve peer review; for this, it must be published in a peer-reviewed journal.

No, a scoping review is not primary research; it is secondary research that involves collecting, organising, and synthesising existing literature, unlike primary research, which generates new data.
Its goal is to map what is known and identify gaps or areas needing further primary research.
