An ''alcohol'' syndrome was developed based on alcohol-related chief complaint keywords sensitive and specific to acute or chronic alcohol ED visits, and validated by an ICD-9 field. The data were aggregated by day from 2008 to 2010, by age and age group. These data were analyzed using general linear modeling (PROC GENMOD), a time trend analysis, and a temporal SaTScan using age groups. Potential time periods of interest were major holidays, days of week, and college start and end periods.
