Data are analyzed from 44 ER sites in 28 ER studies across 16 countries (Argentina, Australia, Belarus, Brazil, Canada, Cezch Rep, China, India, Mexico, Mozambique, New Zealand, Poland, South Africa, Spain, Sweden, U.S.) comprising the combined Emergency Room Collaborative Alcohol Analysis Project (ERCAAP) (1984–2009) (Cherpitel et al., 2003) and the WHO Collaborative Study on Alcohol and Injuries (2001–2002) (WHO Collaborative Study Group, 2005). See Cherpitel (2005) for a more detailed description of the study sites. The WHO study included only those patients arriving at the ER within 6 hours of the injury event. For comparability, ERCAAP data analyzed here were selected to include only those injured patients meeting this 6-hour criterion.
