To include this important effect of patterns of drinking (see also [31]), we will base the estimates of AAFs for injury categories on the number of heavy drinking occasions as estimated by survey, and the RR associated with each heavy drinking occasion. We have recently developed the methodology for estimating such AAFs [225;226]; however, this methodology only accounts for injury effects of drinking on the drinkers themselves. Further adjustments still need to be developed to estimate the overall effect of drinking on injury, including for example, the effect of drunk driving on innocent bystanders who did not consume alcohol.
