Trends in drug-related hospitalisations in Victoria, 1999-2019
- There were 14,251 hospitalisations with a drug-related principal diagnosis in VIC in 2018-19.
- This is equivalent to 217 hospitalisations per 100,000 people, as compared to 190 hospitalisations per 100,000 people in 1999-00 (Figure 1).
- The rate of hospitalisations was higher among males than females in 2018-19 (222 versus 213 hospitalisations per 100,000 people).
- In 2018-19, the rate of hospitalisations was highest among the 20-29 age group, followed by the 30-39 and 40-49 age groups (417, 345, and 307 hospitalisations per 100,000 people, respectively).
- The rate of hospitalisations was highest where there was a principal diagnosis indicating amphetamines and other stimulants (53 hospitalisations per 100,000 people; Figure 2).
- The highest number and rate of hospitalisations was observed in major cities VIC (10,927 hospitalisations,207 hospitalisations per 100,000 people; Figure 3).

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.)

Figure 3. Age-standardised rate (per 100,000 people) of drug-related hospitalisations, by remoteness, Victoria, 2012-13 - 2018-19.
Note: 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. The size (area) of the bubble is proportional to the number of hospitalisations.
