Flags can be split into two distinct categories: clinical flags and psychosocial flags:
Clinical flags are common to many areas of health. If suspected these require urgent further investigation.
Psychosocial flags have been subdivided over the years to reflect the different interactions that can affect recovery. Psychosocial flags allows the physician to identify aspects of the person, their problems and their social context, and how those factors affect the recovery and return to work process. Psychosocial flags provide a framework for assessment and planning, and an indication that someone may not recover as expected, and may need additional support to return to work.
