Flowchart of process used to obtain up to six AIS codes for each injury sustained. The process of assigning AIS codes and mapped codes for two hypothetical injuries are illustrated - I. 5 mm cerebral subdural haematoma, and II. comminuted medial malleolus fracture. Mapped codes (Map98, green; Map08, red; EMap08, brown; and EMap08+F, teal) are derived from codes assigned using AIS08 (AIS08, blue) and AIS98 (AIS98, purple) dictionaries. Free text descriptions may also be used in deriving EMap08+F codes.
