Detection of problem-drinkers in an emergency department using a breathalyser and questionnaire.
Over a 2-week period in January 1990 consecutive adult emergency attenders were breathalysed and screened for problem drinking using the WHO screening instrument. Results were compared with a similar study conducted 8 years previously. Of the patients tested, 12.5% had a positive alcohol in 1990 compared with 16% in 1982. Of those with positive alcohol results, the mean blood alcohol equivalent (BAE) concentration was significantly (p=0.0006) lower in 1990 (73.6+/-65.1; mg/100 ml; mean+/-SD) when compared to those levels found in 1982 (136.9+/-102.4 mg/100 ml). There was also significant reductions in 1990 of positive breath alcohol attenders both from road traffic accidents (p<0.03), and from head injuries (p<0.005) compared to 1982. In 1990 the questionnaire was positive in 23% of attendees. These studies suggest a trend towards less alcohol misuse in emergency department patients, but nevertheless indicate high rates of problem drinking. It is suggested that alcohol breathalysers be available in emergency departments to assist the detection of alcohol misusers and predict alcohol-associated medical problems.
