Formulating a question for systematic review
Question formulation process
  • Systematic Review
  • A systematic review is a literature review
    focused on a single question which tries to
    identify, appraise, select and synthesize
    research evidence relevant to that question.
  • The question addressed is usually evidence of an
    effectiveness of an intervention. This can
    inform policy, or, if insufficient evidence is
    available, will identify a knowledge gap and
    indicate areas where original research is needed.

A systematic review question is composed of the
following elements Subject unit of study (e.g.,
ecosystem, habitat, species, environmental
standard) to which the intervention will be
applied Intervention management regime, policy,
or action Outcome measure all relevant
objectives of the intervention that can be
reliably measured. Measurements of change in the
subject Comparator a control with no
intervention, an alternative intervention or
Before After Control Impact (BACI) studies
After the question Once a question has been
decided the next step is to set out how the
review will be carried out by writing a protocol.
