A Literature Review is focused around a specific topic and is not as structured as a conducting a Scoping or a Systematic Review. Literature reviews are most often used supplementing the writing of papers or reports.
Scoping Review is conducted to provide an overview of the literature
published around a specific topic. An example of this may be
Patient Flow Simulations which may result in describing the various
type of simulation methods (discrete event, multi agent, etc) presented
in the literature, what domains (hospital, wards, etc) simulation has
been applied to and what type of issues may have been addressed
(re-admissions, transfers, capacity).
A Systematic Review is a formal method for answering a specific question in the medical arena. An example of this might be the effect on Length of Stay using Patient Flow Simulations. Two researchers would review all the abstracts related to a search and determine if those abstracts met some criteria. Then those selected abstracts would be used for selecting the full text paper (PDF) and see if the criteria is further met. Kappa scores are calculated at each stage. A description of the literature, and potentially a meta analysis is conducted.
