Mental health readmissions to hospital, 2018
Identifying and definitional attributes
|Metadata item type:||Indicator|
|Short name:||Mental health readmissions to hospital, 2018|
The percentage of in-scope overnight separations from state/territory acute admitted patient mental health care service unit(s) that are followed by readmission to the same or to another public sector acute admitted patient mental health care service unit within 28 days of separation.
Readmissions to an acute admitted patient mental health care service unit following a recent discharge may indicate that inpatient treatment was incomplete or ineffective, or that follow-up care was inadequate to maintain the person’s treatment out of hospital. In this sense, rapid readmissions may point to deficiencies in the functioning of the overall care system.
Avoidable rapid readmissions place pressure on finite beds and may reduce access to care for other consumers in need.
International literature identifies one month as an appropriate defined time period for the measurement of unplanned readmissions following separation from an acute admitted patient mental health care service unit.

Collection and usage attributes
State/territory public acute admitted patient mental health care service units.
The following readmissions are excluded when calculating the numerator:
The following separations are excluded when calculating the denominator:
(Numerator ÷ Denominator) x 100
Number of readmissions to a state/territory public acute admitted patient mental health care service unit(s) occurring within the reference period.
|Numerator data elements:|
Number of in-scope overnight separations from state/territory acute admitted patient mental health care service unit(s) occurring within the reference period.
|Denominator data elements:|
Consumer attributes: age, sex, Socio-Economic Indexes for Areas (SEIFA), remoteness, Indigenous status. Disaggregated data excludes missing or not reported data.
All disaggregated data are to be calculated as at the admission for the first index separation, even if the value is null. The index separation refers to the separation data point included in the denominator data set. The data at admission for the index separation should be used for the associated numerator data pair, when present, and any subsequent denominator and data pairs for a uniquely identifiable person.
|Disaggregation data elements:|
|Unit of measure:||Service event|
Indicator conceptual framework
|Framework and dimensions:||Effective support, care and treatment|
State/territory supplied data.
|Further data development / collection required:|
This indicator cannot be accurately constructed using the Admitted Patient Care National Minimum Data Set (NMDS). While the data set comprehensively provides a collection of separations from Australian public hospitals, its inability to uniquely identify a patient across episodes and across hospitals, and the inability to identify patient transfers into and separations from acute admitted patient mental health care service units, limits its capacity to count readmissions.
There is no proxy solution available. In order to report this indicator at a national level, states and territories are required to individually provide separate indicator data.
A reliable system of patient identifiers within the Admitted Patient Care NMDS is required to enable unique identification of individual consumers across multiple years, multiple admitted episodes and multiple hospitals.
When data for this indicator are requested, jurisdictions are required to answer whether a state-wide unique client identifier system is in place, or some comparable approach has been used in the data analysis to allow tracking of service utilisation by an individual consumer across all public specialised mental health services in the jurisdiction. Collection of this information is aimed at assessing the degree of consistency between jurisdictions in data reported, the result of which are explored in the data quality statement for this indicator.
|Other issues caveats:|
Due to data limitations this indicator cannot differentiate between planned and unplanned readmissions. This indicator does not track readmissions across state and territory boundaries or track movement between public and private hospitals.
