Alcohol-related Injuries at an Emergency Department in Eastern Taiwan

Abstract

Injuries are major causes of mortality and morbidity in Taiwan. Alcohol involvement often plays a role in injuries. The purpose of this study was to determine the prevalence of alcohol-related injuries at an emergency department in Eastern Taiwan and their associated factors. All injured patients who made emergency visits between October 2002 and September 2003 were enrolled. For each patient, the attending nurse completed an injury-coding sheet, which included the results of an assessment of whether the patient had an alcohol odor or alcohol consumption related behavior. Nurses recorded suspicion of alcohol consumption based on possible categories of "no alcohol odor", "alcohol odor", "intoxicated", "suspected" or "unknown". Blood alcohol testing was also performed based on the decision of the attending physician. Injuries were defined as alcohol-related based on the report of "alcohol odor" or "intoxicated" by the nurse or a positive blood alcohol test. Logistic regression was used to assess the significance of the association of possible related factors with alcohol-related injury. A total of 8822 eligible visits were studied and 14% were classified as alcohol-related. The proportion of alcohol-related injuries was 14.9% for vehicle-related injuries, and 51.3% for assaults. Male, young to middle aged, aboriginal ethnicity and visits after midnight were factors associated with increased likelihood of alcohol-related injuries. Multiple logistic regression analysis revealed that the three factors most significantly associated with alcohol-related injuries were visits after midnight (odds ratio, OR, 7.5; 95% confidence interval, CI, 6.4-8.9], assaults (OR, 3.4; 95% CI, 2.3-4.8), and head injuries (OR, 2.7; 95% CI, 2.3-3.2). Injuries were alcohol related in one out of seven patients this study from an emergency department in eastern Taiwan. Ongoing epidemiologic monitoring of the prevalence and nature of alcohol abuse among patients visiting the ED are urgently needed.
