MATCHING CASE METHODOLOGY FOR MEASURING RESTRAINT EFFECTIVENESS

The importance of the matching case methodology is that it utilizes field accident data exclusively -- accidents in which a specific restraint was used are compared to accidents of similar injury potential but whose occupants did not use the restraint being evaluated. The authors cite the Air Cushion Restraint System (ACRS) as an example of the matching case methodology's utility. ACRS effectiveness is about 18% (CI = - 23% to + 56%) for injured occupants at AIS levels equal to or greater than AIS 3, in deployment accidents. It is believed that this is the best, currently available estimate of ACRS field effectiveness.
