HSLS Systematic Review Program

Ask yourself:

• What specific research questions do I want to address?

• How much time do I have to work on the review?

• Do I have a team to assist me?

• How much of the published literature do I need to review?

• Does my lit search need to be reproducible?

Provides an overview of a topic, highlights important or critical aspects of a topic, or traces the historical development of a topic or concept

• Methodology is not standardized

• Journals have varying requirements for formatting and documentation (check before submitting)

Systematically examines the range, extent or nature of literature on a topic or question

• Identifies gaps in existing literature or the value of undertaking a systematic review

• Typically does not include critical appraisal of included studies, but otherwise time and effort requirements are similar to a systematic review
