- Alcohol = alcohol involvement, with or without other drugs/substances.
- Amphetamines (Any) = all amphetamines (e.g. amphetamine, methamphetamine).
- Analgesics = pain relief medications, such as aspirin or paracetamol, and other non-opioid analgesics.
- Antidepressants = antidepressant, such as citalopram or sertraline.
- Antipsychotics = antipsychotic, such as amisulpride or quetiapine.
- Benzodiazepines = benzodiazepines, such as alprazolam or diazepam (may include drugs that act like benzodiazepines, such as zolpidem).
- Cannabis = cannabis or hashish.
- Hallucinogens = hallucinogen, including LSD or mushrooms.
- Heroin = any heroin.
- Illicit Drugs (Any): indicates case where any illicit drug was primarily involved in the event, including heroin, opioids, amphetamines, cannabis, stimulants, hallucinogens, inhalants, or other illicit drugs not explicitly mentioned.
- Inhalants = any volatile substance, inhalant or solvent, such as chrome or petrol.
- Opioids = opioid, including opioid analgesics such as morphine or oxycodone.
- Other Sedatives = a sedative (excluding opioids and benzodiazepines) was involved in the event, such as barbiturates, anesthetics or ketamine.
- Other Stimulants = stimulants, including cocaine or ecstasy.
- Pharmaceutical Drugs (Any): indicates case where a prescription drug was primarily involved in the event, including antidepressants, antipsychotics, benzodiazepines, analgesics, sedatives, pharmacotherapy, steroids or another medication (prescribed or non-prescribed) not explicitly mentioned.
- Pharmacotherapy = synthetic opioids, such as those used in opioid replacement therapy, including methadone and buprenorphine.
- Null refers to either missing or other gender.
Age group categories
- Null refers to missing age
AODstats provides the ability to track trends of acute harms at the community level, and help inform policy and strategies to intervene and minimise the impact or spread of these harms.
This information provides a convenient, interactive, statistical resource for policy planners, drug service providers, health professionals and other key stakeholders, interested in the harms relating to alcohol and other drug use in Victoria.
For further information on the analysis, please see the methods document (the document opens in a new tab).
- Data indicator: Hospital admissions
- Data Source: Victorian Admitted Episodes Dataset (VAED) – Victorian Department of Health.
- Details of data analysis: Using VAED data, hospital admissions with a ‘primary’ diagnosis wholly (or partially) attributable to alcohol or other drugs were included in AODstats. This method considers all those diagnosis fields for each hospital admission where and AOD-related disease condition, based on ICD-10, was the primary reason for the admission. Data presented is based upon residential location.
- Numbers: cell sizes less than 5 are obfuscated in line with ethics and data custodian requirements. Some other categorical data may also be obfuscated if a category can be calculated by subtracting any remaining categories from the total.
- Rates: rates are crude rates, which can allow for adjustment of population sizes across different areas, however these do not adjust for certain demographic attributes (specifically age and sex). The advantage to using crude rates is particularly important from a policy perspective, to understand what is influencing the rates. For example, it is important for policy and services to be aware if an area has more men and younger people.
- Population estimates: ABS estimated resident population (ERP) on age, sex and statistical local areas is used throughout AODstats based on calendar year of data. For financial year datasets, the earliest year is used (e.g. 2012/13, 2012 ERP is used).
There are limitations to using administrative data for purposes other than what it was originally intended when collected. This includes:
- Incomplete or missing data and inadequate coding.
- Some drugs are already in pre-determined drug categories and it is not possible to group them differently or include more specific drug information. In addition, sometimes drug information is not collected and therefore surrogate measures are used. The limitation to this is there will be events that are missed when they should be included and conversely events included when they should not be.
- Location information is dependent upon dataset and the majority of times LGA is the smallest area provided, and sometimes only state based data is available.
- Crude rates are used, which do not allow for certain demographic attributes (age and gender) to be compared accurately across areas, and also rates based on small numbers can produce unstable results.
