This page contains information relevant to both the Online Services Report (OSR) and national Key Performance Indictors (nKPI) collections. Further information specific to each collection is provided in Interpreting OSR data and Interpreting nKPI data.
This page contains general information to aid interpretation of the OSR and nKPI collections. This should be used in conjunction with additional information contained in the:
While some organisations constitute an individual health care clinic, others have multiple clinics, and provide combined data for all their clinics. Other organisations are intermediaries (for example, Primary Health Networks), which might also combine the data for the clinics where they subcontract services.
In both collections:
Each organisation reporting to the OSR and nKPI collections records service provision in their Clinical Information Systems (CIS). While the CISs contain many variables related to individual clients, only those specified as required for the OSR and nKPI collections, aggregated for each organisation, are extracted for use.
Data are aggregated using cohort definitions and specialised software and then submitted to the Australian Institute of Health and Welfare (AIHW) via the Health Data Portal (the HDP). The HDP is the Department of Health’s secure web-based data submission platform.
Many CIS are able to extract, aggregate and upload the de-individualised data directly to the HDP through a direct-load process. Organisations with systems unable to complete the direct-load process can manually enter aggregate data directly into a web-based form through the HDP.
The HDP applies a series of pre-defined validation rules (originally developed by the AIHW) to the data to identify any data quality issues, for example, that the numerator is less than the denominator, that the numerator sums to the denominator and that related indicators or questions are consistent. In addition, the data are compared with data from the previous period and:
If any validation rules are triggered, the organisation is asked to review their data and either amend it, or confirm that it is correct and provide an optional comment.
The data are then submitted to the AIHW for review. Where the AIHW identifies possible errors or inconsistencies in the data, a comment is added to the HDP containing a description of the issue and the organisation is invited to resubmit their data. This process is repeated until no data quality issues are identified, the relevant organisation indicates it is unable or unwilling to resupply corrected data or the reporting period is closed. At this point, the data are considered to be finalised for that organisation.
Where unresolved data quality issues are identified, the AIHW excludes these data from national reporting (this may be a single data item for an organisation or all data for an organisation).
Trends over time are presented where possible, noting that the organisations reporting to the OSR and nKPI collections, and data quality, can vary over time. For example:
Also, unlike in previous years where reporting to the OSR and nKPI collections was a mandatory condition of receiving funding, for 2019–20 and 2020–21, reporting was made voluntary in acknowledgement of the additional pressures on organisations because of the coronavirus disease 2019 (COVID-19) pandemic. This also affected the organisations reporting to the collections in a variety of other ways. See Impact of COVID-19 for more information. Additional information, including important context for interpreting changes in results in the nKPI collection, can be found in the forthcoming Australia’s Health 2022.
The estimated resident population (ERP) used as comparison for the OSR and nKPI client cohorts varies. The ERP chosen, or calculated, for each collection and reporting period is determined based on what is considered to be the most representative population for each.
As the nKPI collection is based on census dates at 30 June and 31 December each year, the most appropriate ERP to use for comparison with Indigenous regular clients is the ERP at the same date as the census date.
As the OSR collection covers a financial year, and estimates as at 30 June not considered appropriate for use when calculating rates based on financial year data, estimates for 31 December (that is, the midpoint of the financial year) are needed.
While the Australian Bureau of Statistics (ABS) produces estimates for the overall Australian population for two time points each year—namely, as at 30 June and 31 December—they only produce estimates for the Indigenous population as at 30 June. As such, ERP at 31 December are calculated by averaging the June population estimates before and after the relevant December. For example, 31 December 2020 estimate = (30 June 2020 estimate + 30 June 2021 estimate)/2.
