The HIA (Head Injury Assessment) protocol is a three-stage process introduced by World Rugby for elite adult teams to assist with the identification, diagnosis, and management of head injuries. The protocol has been developed to support Law 3.11 and Regulation 10, both of which are relevant to the temporary replacement for head injury and the management of concussion. The three stages of the HIA protocol are:
-
Off-field HIA1 Assessment: This is the initial assessment that is conducted off the field by a medical professional to determine if a player has a head injury that requires further evaluation.
-
On-field HIA2 Assessment: If a player fails the off-field HIA1 assessment, they are removed from the game and undergo an on-field HIA2 assessment. This assessment is conducted by a medical professional and involves a series of tests to determine if the player has a concussion.
-
Off-field HIA3 Assessment: If a player fails the on-field HIA2 assessment, they are removed from the game and undergo an off-field HIA3 assessment. This assessment is conducted by a medical professional and involves a more detailed evaluation of the players condition.
The HIA protocol is used to support Law 3.11 and Regulation 10, which allow for temporary substitution for head injury in elite adult rugby. The protocol has been in use since 2014 and is supported by World Rugby. The HIA protocol is used to ensure that players who suffer head injuries are properly evaluated and managed to prevent further injury.
