DSS type:Help on this termNational Minimum Data Set (NMDS)
Scope:Help on this term

The purpose of the Admitted patient care national minimum data set (APC NMDS) is to collect information about care provided to admitted patients in Australian hospitals.

The scope of the APC NMDS is episodes of care for admitted patients in all public and private acute and psychiatric hospitals, free standing day hospital facilities and alcohol and drug treatment centres in Australia. Hospitals operated by the Australian Defence Force, correctional authorities and in Australia's off-shore territories may also be included. Hospitals specialising in dental, ophthalmic aids and other specialised acute medical or surgical care are included.

Hospital boarders and still births are not included as they are not admitted to hospital. Posthumous organ procurement episodes are also not included.

Guide for use:Help on this term

Interaction with the Individual Healthcare Identifier national best endeavours data set (IHI NBEDS)
The APC NMDS and IHI NBEDS work together to enable the reporting of IHI data for admitted episodes of care.
 

Collection methods:Help on this term

Data are collected at each hospital from patient administrative and clinical record systems. Hospitals forward data to the relevant state or territory health authority on a regular basis (e.g. monthly).

National reporting arrangements

State and territory health authorities provide the data to the Australian Institute of Health and Welfare for national collation, on an annual basis.

State and territory health authorities provide the data to the Independent Hospital Pricing Authority for national collation, on a quarterly basis.

Periods for which data are collected and nationally collated

Quarterly or annually (financial year) ending 30 June each year.

When stipulated in a data specification, each record in a data submission will be assigned a unique numeric or alphanumeric record identifier to permit easy referencing of individual records in discussions between the receiving agency and the reporting body. The unique record identifier assigned by the reporting body should be generated in a fashion that allows the associated data record to be traced to its original form in the reporting body's source database.

Reporting jurisdictions may use their own alphabetic, numeric or alphanumeric coding system.

This field cannot be left blank.
