Design Retrospective, cohort study. Setting Elite hockey players from A and B. Subjects 354 subjects in two sub-groups. A: 222 (191 Males/31 Females). B: 132 (114 Males/18 Females). Intervention Subjects were educated and baseline tested at the start of the 2011–12 season using Symptom Inventory, SCAT2, BESS and neuro-cognitive testing. The Zurich 2008 RTP protocol was utilised. Subjects were followed with serial testing until recovered to baseline or within 5% of baseline. Medical authorisation was given to RTP. Outcome Measures The incidence of concussion and the average RTP in the two groups. Results A. Concussion incidence – Overall 23%  ▸ A 18% (n=39)  ▸ B 32% (n=42) B. RTP (Average No. Days to RTP) Overall: 22  ▸ A: 27  ▸ B: 14 Conclusions Concussion incidence approximated that reported by Echlin. The higher incidence in the B group reflects the experience of coaches and full-time athletic therapists in recognising and dealing with concussions, and a willingness to report concussion injury. Overall RTP time was longer in both groups than the previously reported 12.8 days average. For B, the RTP time was less than A (14 vs 27 days), reflecting daily access to supportive care (athletic therapists and physician), daily access to the gym for Steps 2 and 3, and daily ice-time for Steps 4 and 5 of the RTP protocol.
