National Healthcare Agreement: PI 21-Treatment rates for mental illness, 2012
|Quality statement summary:|
The AIHW prepared the denominator and calculated the indicator based on numerators supplied by other data providers. The AIHW is an independent statutory authority within the Health and Ageing portfolio, which is accountable to the Parliament of Australia through the Minister. For further information see the AIHW website.
Numerators for this indicator were prepared by State and Territory health authorities, the PMHA, DoHA and DVA and quality-assessed by the AIHW.
The AIHW drafted the initial data quality statement. The statement was finalised by AIHW following input from State and Territory health authorities, PMHA, DoHA and DVA. The AIHW did not have the relevant datasets required to independently verify the data tables for this indicator.
The State and Territory health authorities receive these data from public sector community mental health services. States and territories use these data for service planning, monitoring and internal and public reporting.
The PMHA’s Centralised Data Management Service provided data submitted by private hospitals with psychiatric beds. The data are used by hospitals for activities such as quality improvement.
DoHA MBS and DVA TAS data
Medicare Australia (now Department of Human Services – Medicare) processes claims made under the Medicare Australia Act 1973. These data are then regularly provided to DoHA. Medicare Australia also processes claims for DVA Treatment Card holders made through the MBS under the Veterans’ Entitlements Act 1986; Military Rehabilitation and Compensation Act 2004 and Medicare Australia Act 1973. All claiming data is regularly provided to DVA as per the Memorandum of Understanding between Medicare Australia and DVA.
The reference period for these data is 2009‑10.
Information is available in the COAG National Action Plan on Mental Health — progress report 2009‑10.
MBS statistics are available at:
Information is available for MBS data from:www.health.gov.au/internet/mbsonline/publishing.nsf/content/medicare-benefits-schedule-mbs-1
Estimates are based on counts of individuals receiving care within the year, by each service type, where each individual is generally counted once regardless of the number of services received. Persons can receive services of more than one type within the year; a count of persons receiving services regardless of type is not available.
A number of persons receiving mental health treatment are not captured in these data sources. These include:
There is likely to be considerable overlap between the DoHA MBS and DVA TAS data and private data, as most patients accessing private hospital services would also access MBS services.
Person counts for State and Territory mental health services are counts of persons receiving one or more service contacts provided by public sector community mental health services. South Australia submitted data that were not based on unique patient identifier or data matching approaches.
Private hospital estimates are counts of individuals receiving admitted patient specialist psychiatric care in private hospitals.
DoHA MBS and DVA TAS data
Data are counts of individuals receiving mental health-specific MBS services for which Medicare Australia has processed a claim.
Analyses by State and Territory, remoteness and socioeconomic status are based on postcode of residence of the client as recorded by Medicare Australia at the date of last service processed in the reference period. As clients may receive services in locations other than where they live, these data do not necessarily reflect the location in which services were received.
DVA clients comprised less than 2 per cent of people receiving Australian Government (Medicare Benefits Scheme- and DVA-funded) clinical mental health services.
Cells have been suppressed to protect confidentiality (where the presentation could identify a patient or a single service provider).
State and Territory jurisdictions differ in their capacity to provide accurate estimates of person receiving services (see above). Additionally, jurisdictions differ in their approaches to counting clients under care. For example, people who are assessed by a mental health service but do not go on to be treated for a mental illness are included in the data by some jurisdictions but not others. Therefore, comparisons between jurisdictions should be made with caution.
The Indigenous status data should be interpreted with caution due to the varying and, in some instances, unknown quality of Indigenous identification across jurisdictions. Indigenous status was missing or not reported for around 10 per cent of all clients.
Not all private psychiatric hospitals are included in the PMHA’s Centralised Data Management Service (CDMS).
In 2009–10, those that are included account for approximately 85 per cent of all activity in the sector. The data provided are an estimate of overall activity.
Actual counts are multiplied by a factor that accounts for the proportion of data missing from the CDMS collection. That adjustment is performed at the level of State and Territory and also financial year, since non-participation rates varied from state to state and financial year.
Indigenous status information is not collected for these data.
DoHA MBS and DVA TAS data
As with any administrative system a small degree of error may be present in the data captured.
Data used for statistical purposes are based on enrolment postcode of the patient. This postcode may not reflect the current postcode of the patient if an address change has not been notified to Medicare Australia.
The data provided are based on the date on which the claim was processed by Medicare Australia, not when the service was rendered. The use of data based on when the claim was processed, rather than when the service was rendered, produces little difference in the total number of persons included in the numerator for the reference period.
People who received more than one type of service are counted once only in the calculations for this indicator.
DoHA MBS data presented by Indigenous status have been adjusted for under-identification in the Medicare Australia Voluntary Indigenous Identifier (VII) database. Indigenous rates are therefore modelled and should be interpreted with caution. These statistics are not derived from the total Australian Indigenous population, but from those Aboriginal and Torres Strait Islander people who have voluntarily identified as Indigenous to Medicare Australia. The statistics have been adjusted to reflect demographic characteristics of the overall Indigenous population, but this adjustment may not address all the differences in the service use patterns of the enrolled population relative to the total Indigenous population. The level of VII enrolment (51 per cent nationally as at August 2010) varies across age-sex-remoteness-State/Territory sub-groups and over time which means that the extent of adjustment required varies across jurisdictions and over time. The methodology for this adjustment was developed and verified by the AIHW and DoHA for assessment of MBS and PBS service use and expenditure for Indigenous Australians. For an explanation of the methodology, see Expenditure on health for Aboriginal and Torres Strait Islander people 2006‑07.
DVA TAS data are not available by Indigenous status.
There has been no major change to the methodology used to collect the data in 2009‑10 for the majority of jurisdictions, therefore data is comparable across years.
However, New South Wales implemented a state wide unique patient identifier for mental health care in 2009. New South Wales has indicated that there are differences in the completeness of coverage between areas and over time.
In 2009–10 Tasmania has implemented a system to reduce duplication of clients accessing mental health services across the state. This has resulted in an apparent decrease in the number of clients.
In past years there has been variation in the underlying concept used to allocate remoteness and socioeconomic status across jurisdictions (i.e. location of service provider, location of client or a combination of both). In addition, the underlying concordances used by jurisdictions to allocate remoteness may vary. In 2009–10, remoteness and socioeconomic status have been allocated using the SLA of the client at last contact. For 2009–10 data all jurisdictions have used the same concordance and proportionally allocated records to remoteness and SEIFA categories. Comparisons over time for remoteness and socioeconomic status should therefore be interpreted with caution.
There has been no change to the methodology used to collect the data in 2009‑10. Therefore, the data are comparable to previous reporting periods.
DoHA MBS and DVA TAS data
The same methodology to attribute demographic information to the data has been used in 2009‑10 as in previous reporting periods.
MBS items 81325 and 81355 were added from 1 November 2008. These items relate to mental health or psychological services provided to a person who identified as being of Aboriginal or Torres Strait Islander descent.
As of 1 January 2010, a new item (2702) has been introduced for patients of GPs who have not undertaken mental health skills training. Changes have been made to the existing item 2710 to allow patients of GPs who have undertaken mental health skills training to access a higher rebate. Both of these items relate to the preparation of a GP mental health treatment plan.
Caution should be taken when interpreting Indigenous rates over time. All other data can be meaningfully compared across reference periods.
The AIHW publication series Mental health services in Australia contains data that is comparable in coverage (using different MBS item splits) and includes a summary of MBS mental health-related items.
The data used in this indicator are also published in the COAG National Action Plan on Mental Health — progress report 2009‑10. There may be some differences between the data published in these two sources as:
The indicator specifications and analysis methodology used for this report are equivalent to the National Healthcare Agreement: Performance report for 2009‑10.
