Systematic Reviews

Selecting the right review type for your research question is the first step for a successful review project. The following tools (or a librarian) can help you decide which review type is right for you:

In addition to the traditional Systematic Review, here are some other common review types:

Scoping or Mapping Review

• Answers a broad, topical question or questions 
• Risk of bias/critical appraisal not required 
• Synthesis is categorical for scoping review 
• Synthesis is a visual map for mapping review 

Sample Question (Scoping Review): What are the various strategies that have been used to engage patients and families in pediatric health research?

Sample Article (Scoping Review): Flynn R, Walton S, Scott SD. Engaging children and families in pediatric health research: a scoping review. Res Involv Engagem. 2019 Nov;5(32). 

Sample Question (Mapping Review): Why do patients with ‘primary care sensitive’ problems seek help from ambulance services?

Sample Article (Mapping Review): Booker, Matthew J., Ali R. G. Shaw, and Sarah Purdy. Why do Patients with 'Primary Care Sensitive' Problems Access Ambulance Services? A Systematic Mapping Review of the Literature. BMJ Open 2015, 5.5.

Integrative Review

• Summarizes literature about a healthcare problem or phenomenon, potentially utilizing both empirical and theoretical literature 
• Allows for the combination of publications with diverse methodologies (e.g. experimental and non-experimental research) 
• Popular in nursing research literature 

Sample Question: What factors are associated with major depression and suicide risk among nursing professionals?

Sample Article: Silva, Tavares, N. V. da S., Alexandre, A. R. G., Freitas, D. A., Brêda, M. Z., Albuquerque, M. C. D. S. de, & Melo, V. L. de N. (2015).

Rapid Review

• A systematic review with shortcuts (e.g. a limited search) 
• Useful for addressing issues that need a quick decision, such as developing policy recommendations or treatment recommendations for emergent conditions. 
• Enables a faster review process but may introduce bias 

Sample Question: Are digital contact tracing technologies effective during infectious disease outbreaks?

Sample Article: Anglemyer A, Moore THM, Parker L, Chambers T, Grady A, Chiu K, Parry M, Wilczynska M, Flemyng E, Bero L. Digital contact tracing technologies in epidemics: a rapid review. Cochrane Database  of Systematic Reviews 2020, Issue 8. Art. No.: CD013699.

Umbrella Review

• A review of other systematic reviews 
• Often attempts to answer a broader question than a systematic review typically would. 
• Useful when there are competing interventions to consider. 

Sample Question: What is the global COVID-19 vaccine acceptance rate, and what factors determine that acceptance rate?

Sample Article: Abate BB, Tilahun BD, Yayeh BM. Global COVID-19 vaccine acceptance level and its determinants: an umbrella review. BMC Public Health. 2024 Jan 2;24(1):5. doi: 10.1186/s12889-023-17497-4.
