Most common principal diagnoses assigned to Australian emergency department presentations involving alcohol use: a multi-centre study

Abstract

Objectives: Alcohol is the most widely consumed psychoactive substance in Australia and the consequences of alcohol consumption have enormous personal and social impacts. This study aimed to describe the principal diagnoses of emergency department (ED) presentations involving alcohol use in the previous 12 hours at eight hospitals in Victoria and the Australian Capital Territory, Australia. Methods: Twelve months’ data (1 July 2018 – 30 June 2019) were collected from eight EDs, including demographics, ICD-10 codes, hospital location and self-reported drinking in the preceding 12 hours. The ten most common ICD-10 discharge codes were analysed based on age, sex and hospital geographic area. Results: ICD codes pertaining to mental and behavioural disorders due to alcohol use accounted for the highest proportion in most EDs. Suicide ideation/attempt was in the five highest ICD codes for all but one hospital. It was the second most common alcohol-related presentation for both males and females. Conclusions: Alcohol plays a major role in a range of presentations, especially in relation to mental health and suicide. Implications for public health: The collection of alcohol involvement in ED presentations represents a major step forward in informing the community about the burden of alcohol on their health resources.
