‘Preloading’ is a phenomenon where people drink alcohol at a  private residence before going out. We aimed to identify whether preloading is a  risk factor for alcohol-related emergency department attendance. We also wanted  to identify where people became injured or unwell. 
We approached 1,079 patients. One hundred sixty-one had  suffered an alcohol-related problem while out drinking; 27% of women and 14% of  men had their first drink at home. There was no particular presentation or age  group that was associated with preloading. Seventy percent of patients stated  that they had drunk most of their alcohol at a public place; 76% of patients  suffered their alcohol-related problem at a site different from where they had  drunk most of their alcohol or where they had had their first drink.  
Preloading is more common in women than men. Preloading is  common in alcohol-related emergency department attendances. The proportions of  patients preloading in this study are lower than in other studies conducted in  different environments. 
Preloading is not a risk factor for alcohol-related  emergency department attendance. Polices to reduce alcohol-related harm should  continue to focus on bars, nightclubs and pubs.
