KPIs for Australian Public Mental Health Services: PI 02 – Mental health readmissions to hospital, 2020– (Service level)
Identifying and definitional attributes
|Metadata item type:||Indicator|
|Short name:||MHS PI 02: Mental health readmissions to hospital, 2020– (Service level)|
|Registration status:||Health, Standard 13/01/2021|
The percentage of in-scope overnight separations from the mental health service organisation’s acute psychiatric inpatient unit that are followed by readmission to the same or to another public sector acute psychiatric inpatient unit within 28 days of discharge.
NOTE: This indicator is related to Mental health readmissions to hospital (Jurisdictional level). There are no technical differences in the calculation methodologies between the Service level version and the Jurisdictional level version of this indicator.
Readmissions to a psychiatric facility following a recent separation 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 psychiatric inpatient service.

Levels at which the indicator can be useful for benchmarking:
|Further data development / collection required:|
This indicator cannot be accurately constructed using the Admitted patient care 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 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.
|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.
