This summary report presents findings on all drug-induced deaths (i.e., overdose and other drug-induced deaths where drugs have been deemed the underlying cause of death) in Victoria from 1999-00 to 2020-2021.

There were 15,743 hospitalisations with a drug-related principal diagnosis in Victoria in 2020-21, equivalent to 0.54% of all hospitalisations in Victoria.

This is equivalent to 247 hospitalisations per 100,000 people, which was a significant increase from 2019-20 (216 hospitalisations per 100,000 people; p<0.001), and the highest rate over the course of monitoring.

These findings are part of the national report Trends in drug-related hospitalisations in Australia, 1999-2021.

NIDIP drug-related hospitalisations 2020-21 - VIC

Report breakdown

Sex

The rate of hospitalisations was higher among males than females in 2020-21 (251 versus 244 hospitalisations per 100,000 people, respectively).

Age

In 2020-21, the rate of hospitalisations was highest among the 20-29 age group, followed by the 30-39 and 40-49 age groups (532, 417, and 272 hospitalisations per 100,000 people, respectively). Among both males and females, the rates of drug-related hospitalisations were highest in the 20-29 age groups.

Remoteness Area of Usual Residence

The highest number and rate of hospitalisations in 2020-21 was observed in major city areas (12,279 hospitalisations, 242 hospitalisations per 100,000 people).

External Cause of Drug Poisoning

In 2020-21, 44% of drug-related hospitalisations in Victoria were due to drug poisoning. Furthermore, 68% of drug poisoning related hospitalisations were intentional (75 hospitalisations per 100,000 people) and 19% were unintentional (20 hospitalisations per 100,000 people).

Drug Type 

In 2020-21, the rate of hospitalisations was highest where there was a principal diagnosis indicating amphetamine-type stimulants (64 hospitalisations per 100,000 people).

Compared to 2019-20, there were significant increases in 2020-21 in the rates of hospitalisations related to: amphetamine-type stimulants; antiepileptic, sedative-hypnotic and antiparkinsonism drugs; non-opioid analgesics; opioids; cannabinoids; and cocaine (p<0.050).

Age-standardised rate per 100,000 people of drug-related hospitalisations, by sex, Victoria, 1999-00 to 2020-21.

Note: From 1st July 2011 to 30th June 2013 (i.e., between 2011-12 and 2012-13), there was a large decrease in public hospitalisations reported for the Victorian Admitted Episodes Dataset (VAED) because episodes where the patient’s entire care is provided in the emergency department were not considered for admission, irrespective of whether a criterion for admission is met. From 2013-14 onwards, “ED-only admissions” were largely replaced with admissions to Short Stay Observation Units.

Age-standardised rate per 100,000 people of drug-related hospitalisations, by remoteness, Victoria, 2012-13 to 2020-21.

Note: The size (area) of the bubble is proportional to the number of hospitalisations. The number of hospitalisations for remote and very remote Victoria in each year were small (less than or equal to 10) thus age-standardised rates were not calculated. Please refer to our methods document for details. Data on remoteness are only available from 2012-13.

Age-standardised rate per 100,000 people of drug-related hospitalisations, by principal diagnosis of mental and behavioural disorder due to substance use (A) and external cause of poisoning (B), Victoria, 1999-00 to 2020-21.

Age-standardised rate per 100,000 people of drug-related hospitalisations, by drug identified in the principal diagnosis, Victoria, 1999-00 to 2020-21.

Note: Age-standardised rates were not calculated if the number of hospitalisations was less than or equal to 10 (please refer to our methods document for details). Suppressed data are visible as gaps in the data series.
