National Healthcare Agreement: P21-Treatment rates for mental illness, 2010
|Quality statement summary:|
The Australian Institute of Health and Welfare (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 and the Department of Health and Ageing (DoHA) and quality-assessed by the AIHW.
The AIHW and DoHA drafted the initial data quality statement. The statement was finalised by AIHW following input from state and territory health authorities, PMHA and DoHA. 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 (CDMS) provided data submitted by private hospitals with psychiatric beds. The data are used by hospitals for activities such as quality improvement.
Medicare Australia collects the MBS data under the Medicare Australia Act 1973. These data are then regularly provided to DoHA. The MBS claims data are an administrative by-product of Medicare Australia administering the Medicare fee-for-service payment systems.
|Timeliness:||The reference period for these data is 2007–08.|
Information is available in the COAG National Action Plan on Mental Health—progress report 2007–08.
Medicare claims statistics are available at:
Disaggregation of MBS data by SEIFA is not publicly available elsewhere.
Information is available for MBS claims data from:
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 MBS data and private hospital data, as most patients accessing private hospital services would access MBS items in association with the private hospital service.
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 and Tasmania 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.
MBS are counts of individuals receiving mental health specific Medicare services for which claims data are available.
Analyses by state/territory, remoteness and SEIFA are based on postcode of residence of the client as recorded by Medicare Australia at the date of last service received 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. Further, all MBS services received by clients who moved location during the reference period are allocated to the postcode of their address at date of last service received.
MBS claims that are reimbursed through the Department of Veterans’ Affairs are not included in this measure.
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 for 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. The Other Australians category includes patients where Indigenous status was missing or not reported (around 10% of all clients).
Not all private psychiatric hospitals are included in the PMHA’s CDMS. Those that are included accounted for approximately 75% 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, since non-participation rates varied between jurisdictions.
Indigenous status information is not collected for these data.
As with any administrative system a small degree of error may be present in the data captured.
Medicare claims 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 a Medicare 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 MBS service are counted once only in the calculations for this indicator.
MBS data on Indigenous status are not published for this performance indicator. Indigenous identification is reported voluntarily by Indigenous Medicare enrolees and there is good evidence that the data significantly under-enumerates Indigenous persons.
Cells have been suppressed to protect confidentiality (where the presentation could identify a patient or a single service provider), where rates are likely to be highly volatile (for example, the denominator is very small), or data quality is known to be of insufficient quality (for example, where Indigenous identification rates are low).
The data used in this indicator are also published in the COAG National Action Plan on Mental Health—progress report 2007–08. There may be some differences between the data published in these two sources as in the COAG National Action Plan on Mental Health—progress report 2007–08:
