Screening questionnaires about alcohol use now routinely ask about prior blackout experiences, which could make it easier to target and find individuals who need help. Simply asking about the amount an individual has drunk was not found to be effective. These interventions are not time-consuming or expensive, making Miller hopeful that she and colleagues can build upon them to develop even more effective interventions.

Other researchers hope that asking about previous blackouts will in turn help reduce other types of risky behaviour. For those who experience regular blackouts, a good first step is to better monitor your own alcohol intake and ask friends around you to do the same.
