PICOS (Population, Intervention, Comparison, Outcome, Study Type) framework.

PICOS Criteria	Explanation
Population	Healthcare professionals working in mental health settings OR patients with a psychiatric disorder cared for by mental health care providers.
Intervention	The use of PGx Testing during prescribing of a psychotropic medicine.
Comparison	* Not applicable.
Outcome	Primary qualitative or quantitative data collected pre-, post-, or during PGx implementation, in the context of psychotropic prescribing.
Study Type	Qualitative or quantitative studies

Description: Breakdown of the PICOS criteria was used to specify the search strategy deployed during the review screening process. * A comparator was not required, as the review did not aim to assess PGx clinical effectiveness, and instead explored barriers and facilitators to implementing PGx.
