Does an assessment aid improve Glasgow Coma Scale scoring by helicopter rescuers in Hong Kong: A randomised controlled trial
2018
Abstract Background Glasgow Coma Scale (GCS) is one of the most commonly used patient assessment tools. This study aimed to determine whether an assessment aid can improve the GCS scoring accuracy by helicopter rescuers in Hong Kong. Methods In this randomised controlled trial, Air Crewman Officers (ACMOs) of Government Flying Service in Hong Kong were randomised into two groups, with and without assessment aid. The group with the assessment aid was provided a printed copy of the GCS scoring table while watching the patient simulated videos. Ten videos with GCS scores ranging from 3 to 15 were used to test the performance of total GCS (tGCS) and motor component of GCS (mGCS) scoring. Results 78% ( n =25/32) of ACMOs participated in the study. By comparing the groups with and without an assessment aid, there was no significant difference in the accuracy of tGCS score (60% versus 60%; p =0.85) or mGCS score (80% versus 80%; p =0.75). Overall, mGCS has a higher accuracy than tGCS ( p Conclusion The use of an assessment aid did not improve GCS scoring by helicopter rescuers. The assessing of mGCS was more accurate than tGCS, further supporting the use of mGCS for prehospital conscious level assessment.
