Abstract Objectives: The Rugby Football Union (RFU) launched a campaign known as HEADCASE to increase knowledge around concussion and to set out a graduated return to play (GRTP) protocol for clubs to follow. This study aimed to understand if that knowledge would lead to greater adherence to the GRTP protocols as knowledge around the long-term effects of concussion increases and to further understand if an external pressure such as an amateur rugby player’s profession would change that adherence. Design: A cross-sectional study used a questionnaire to establish the basic understanding of how a concussion presents and the causes amongst a level 6 rugby club. Players (n=21), coaches (n=1) and first aiders (n=2) took part in the study. Interviews were then conducted from randomly selected participants (n=4) to further understand finer details of the RFU’s HEADCASE protocol. Main outcome measures: A modified Rosenbaum Concussion Knowledge and Attitudes Survey- Student Version (RoCKAS-ST) was digitally distributed to a level 6 amateur rugby union club. Responses were then evaluated to give a concussion knowledge index (CKI) and concussion attitude index (CAI). Semi-structured interviews were conducted with a thematic review to observe common themes. Results: High levels of knowledge do not appear to significantly change attitudes that would be considered “unsafe”. There does not appear to be a link between an amateur player’s profession and their attitude to adhering to a GRTP protocol. Conclusions: Rosenbaum Concussion The findings show a greater knowledge of concussion than amateur clubs around the world with a majority of “safe” attitudes being demonstrated. However there are still “unsafe” attitudes displayed that may representative of the culture within the sport rather than knowledge gaps.
