Available data

Data is available from three health data collections.

Victorian Admitted Episodes Dataset

The Victorian Admitted Episodes Dataset (VAED) collects morbidity data on all admitted patients from Victorian public and private acute hospitals including rehabilitation centres, extended care facilities and day procedure centres.

Victorian Emergency Minimum Dataset

The Victorian Emergency Minimum Dataset (VEMD) collects information on emergency presentations at Victorian public hospitals that receive the non-admitted emergency services grant, and other hospitals as designated by the Department of Health and Human Services.

Elective Surgery Information System

The Elective Surgery Information System (ESIS) collects electronic episode-level elective surgery waiting list information from the major Victorian metropolitan and rural public hospitals.

What the data is used for

The Department of Health and Human Services uses information from these collections to:

  • fund public hospitals equitably
  • support health service planning
  • inform policy
  • support epidemiological research.

The Agency uses information from these collections to:

  • track performance and its reporting.

Individual hospital data

As statistical data, the collections do not form part of, and are not suitable for use in, the treatment of patients. Hospitals maintain comprehensive patient records for this purpose.

For activity and performance information for individual hospitals, health services and statewide data see Victorian Health Services Performance data.


Data release and confidentiality

The Agency’s policy on releasing data aims to protect the privacy of individuals, small community groups and private hospitals. All data to be released is based on de-identified patient level data.

When considering a request for HOSdata, the Agency must be satisfied that the data items requested cannot identify the patients involved, and that the data items requested are appropriate for the proposed use of the data. 

If the data is to be used for a research project the project must be approved by a properly constituted Human Research Ethics Committee (HREC). The data recipient must accept the Agency’s standard conditions of release. Note that this is only supplied once an application has been received and assessed by the HOSdata Front Desk.
