Coverage/Scope:

All public mental health service organisations acute psychiatric inpatient units.

Community mental health service contacts where a consumer and/or their carer/support person participated in the contact are in scope for the numerator. The following separations are excluded:

• same day separations
• statistical and change of care type separations
• separations that end by transfer to another acute or psychiatric hospital
• separations that end in death
• separations where length of stay is one night only and procedure code for Electroconvulsive therapy (ECT) is recorded
• separations that end by transfer to community residential mental health services.

The following community service contacts are excluded:

• community service contacts on the day of separation;
• contacts where neither a consumer nor their carer/support person participated.

Methodology:

• Implementation of this indicator requires the capacity to track service use across inpatient and community boundaries and is dependent on the capacity to link patient identifiers.
• For the purpose of this indicator, when a mental health service organisation has more than one unit of a particular admitted patient care program, those units should be combined.
• All acute admitted mental health service units are in-scope for this indicator, including short-stay units and emergency acute mental health admitted units.
• The categorisation of the admitted patient unit is based on the principal purpose(s) of the admitted patient care program rather than the classification of individual consumers.
• 'Carer/support person' is defined by local legislation and policies for the relevant jurisdiction.
• One of the following ECT procedure codes are recorded:
  * ACHI 5th edition (2006–2008) use procedure codes 93340-02 and 93340-03.
  * ACHI 6th to 9th editions (2008 to 2015) use procedure codes 93341-00 to 93341-99.
  * ACHI 10th (2015 to current) edition use procedure codes 14224-0 to 14224-06.
  * ACHI 5th to 10th editions (2006 to current) ECT Block 1907 may be selected to capture all data regardless of code changes over time.

(Numerator ÷ Denominator) x 100

Number of in-scope separations from the mental health service organisation’s acute psychiatric inpatient unit(s) for which a public sector community mental health service contact in which the consumer or their carer/support person participated, was recorded in the 7 days following that separation.

Number of in-scope separations for the mental health service organisation’s acute psychiatric inpatient unit(s).

Service variables: target population.

Consumer attributes: age, Socio-Economic Indexes for Areas (SEIFA), remoteness, Indigenous status, and consumer participated in the mental health service contact.

Levels at which indicator can be useful for benchmarking:

• service unit
• mental health service organisation
• regional group of services
• state/territory.

This indicator cannot be accurately constructed using the Admitted Patient and Community Mental Health Care National Minimum Data Sets because they do not share a common unique identifier to allow persons admitted into hospital to be tracked in the community services data. Additionally, states and territories vary in the extent to which state-wide unique identifiers are in place to allow accurate tracking of persons who are seen by multiple organisations.

There is no proxy solution available. To construct this indicator at a national level requires separate indicator data to be provided individually by states and territories.

Development of a system of state-wide unique patient identifiers within all mental health NMDSs is needed to improve this capacity.

Collection of carer/support person contacts has been added in the 2020 indicator specifications. However, not all jurisdictions will be able to supply this data in 2020. Data development work to consistently capture information about carers in state/territory data systems is necessary to allow further development of this indicator.

• The reliability of this indicator is dependent on the implementation of state-wide unique patient identifiers as the community services may not necessarily be delivered by the same mental health service organisation that discharges the consumer from hospital care. Access to state-wide data is required to construct this indicator accurately.
• When reported at an individual service or catchment level, interpretation of this indicator needs to consider that catchment areas for inpatient and ambulatory services may differ. Ideally services should implement processes to ensure a shared responsibility for following up with consumers who reside out of area.
• This measure does not consider variations in intensity or frequency of service contacts following separation from hospital.
• This measure does not distinguish qualitative differences between phone and face-to-face community contacts.
