A study investigated whether the regional implementation of prohibitive liquor legislation to limit the sale of and access to alcohol in Australia, led to a sustained reduction in the incidence of assault resulting in facial injury, as seen in patients presenting to a level 1 trauma hospital.
A retrospective observational cohort study was conducted to document patients who were identified as an acute hospital presentation of assault occasioning facial injury. The period of study was 2003-2015; this ensured a similar period of time before and after the implementation of the legislation in 2008.
A statistical analysis was undertaken to assess the rates of change in oral and maxillofacial (OMF) assault admissions pre and post legislation. The study found that pre-legislation numbers of OMF assaults increased at a rate of 14% per annum and then decreased at a rate of 21% per annum post legislation (31% relative rate ratio reduction). Similar trends were seen for all males, males aged 18-35 years, and males where alcohol was recorded at clinical presentation.
The introduction of ‘last drinks’ and ‘lock out’ legislation has led to a significant and sustained reduction in assaultive alcohol related facial injury in Newcastle, the study finds.
