This appendix includes data quality summaries and additional detailed information relevant to interpretation of the information in this report.
States and territories are primarily responsible for the quality of the data they provide. However, the AIHW undertakes extensive validations on receipt of data, checking for valid values, logical consistency and historical consistency. Where possible, data in individual data sets are checked with data from other sets. Potential errors are queried with jurisdictions, and corrections and resubmissions may be made in response to these queries. Except as noted the AIHW does not adjust data to account for possible data errors or missing or incorrect values.
Complete data quality statements for the National Non-admitted Patient Care (aggregate) Database (NNAPC(agg)D) and the National Non-admitted Patient (episode-level) Database (NNAP(el)D) are available online in the AIHW's online metadata registry METEOR.
The NNAPC(agg)D is based on data provided for the:
It holds aggregated clinic-level data on the type of outpatient clinic, counts of individual and group service events, the funding source for the service events, and whether the service involved care from multiple health care providers.
The reference period for this data set is 2017–18. The data set includes records for non-admitted patient service events provided between 1 July 2017 and 30 June 2018.
For 2017–18, the scope of the NAPC NMDS was non-admitted patient service events provided by public hospitals. It also included public hospital services that were funded through the jurisdictional health authority or Local Hospital Network.
For 2017–18, the scope of the NAPCLHN NBEDS (METeOR identifier 649576) is non-admitted patient service events provided by:
Between 2013–14 and 2014–15, the scope of the NAPC NMDS changed – from a focus on activity-based funded hospitals to all public hospitals, resulting in increases in the number of hospitals and other services reporting for the NNAPC(agg)D between 2013–14 and 2014–15. Table A1, available to download in the Data section illustrates the changes is coverage for the data provided for the NNAP(agg)D between 2013–14 and 2017–18.
For 2014–15 to 2017–18, information was also provided for non-admitted patient service events at the LHN-level, at state/territory health authority-level, for other public hospital services and by some private hospitals providing public patient non-admitted patient services under contract.
The NNAP(el)D is based on the Non-admitted patient National Best Endeavours Data Set (NAP NBEDS, METeOR identifier 650086).
It holds episode-level data including selected patient characteristics; the type of outpatient clinic; whether the episode was an individual or a group service event; the source of the request for service; the service delivery setting; the service delivery mode, the type of care provided, whether the service involved care from multiple health-care providers and the funding source for the service event.
The reference period for this data set is 2017–18. The data set includes records for non‑admitted patient service events provided between 1 July 2017 and 30 June 2018.
In 2017–18, the scope of the NAP NBEDS was defined as non-admitted patient service events in:
For the NNAP(el)D, a record is included for each service event, not for each patient, so patients who receive more than one non-admitted patient service event in the year have more than one record in the NNAP(el)D.
Before 2015–16, the scope of the NAP NBEDS was defined as non-admitted patient service events in activity-based funded hospitals only. Between 2014–15 and 2015–16, the scope of the NAP NBEDS changed to include public hospitals and other services that were not activity-based funded. Therefore, changes in the numbers of service events reported between 2013–14 and 2017–18 should be treated with caution.
Table A2, available to download in the Data section, illustrates the changes is coverage for the data provided for the NNAP(el)D between 2013–14 and 2017–18.
Changes to the collection of non-admitted patient care over time mean that these data are not comparable over time.
Before 2013–14, information on non-admitted patient care was reported using different clinic categories and counting units.
Time series information between 2013–14 and 2017–18 is not presented due to changes that affect the interpretation of these data, including:
For the NAPC NMDS, the NAPCLHN NBEDS and the NAP NBEDS, a non-admitted patient service event that involves multiple health professionals (and related diagnostic services) within the same clinic is counted as one service event. If a patient attends more than one clinic on the same day, then each attendance is counted as a separate service event.
In AIHW reports for the 2012–13 financial year and earlier, non-admitted patient occasions of service were counted as the number of services provided to a patient in each functional unit of a health service establishment. Each diagnostic test or simultaneous set of related diagnostic tests for a patient were counted as a separate occasion of service.
Therefore, the data presented for non-admitted patient service events in this report are not comparable with data reported for non-admitted patient occasions of service in reports for the 2012–13 reference year and earlier periods.
In addition, the activity of the clinic 40.01 Aboriginal and Torres Strait Islander people’s health clinic (which was in-scope for 2013–14 and 2014–15) was out-of-scope for 2015–16 to 2017–18.
In 2013–14 and 2014–15, for the NAPC NMDS, the NAPCLHN NBEDS and the NAP DSS/NBEDS, each session of renal dialysis, total parenteral and enteral nutrition, and ventilation performed by the patient in their own home was counted as a non-admitted patient service event.
For 2015–16 to 2017–18, the counting rules for some home-delivered non-admitted patient services changed to ‘temporal care bundling’. Temporal care bundling means that all non-admitted patient sessions performed per month are ‘bundled’ and counted as one non-admitted patient service event per patient per calendar month regardless of the number of sessions (IHPA 2016).
This resulted in a marked decrease in reporting of non-admitted patient services events in total, and for Procedural clinics, and for the following Tier 2 clinics:
Between 1993–94 and 2013–14, the AIHW reported aggregated non-admitted patient occasions of service data from the National Public Hospital Establishments Database (NPHED), which covered a wider range of non-admitted patient care than is collected for the NNAPC(agg)D and NNAP(el)D. From 2014–15 onwards, information has not been available for:
