1.2. Changes for 2023-24

The specific detailed changes to the 2023-24 specifications (version 5.51), compared to the 2022-23 (version 5.50) specifications, are detailed below.

1.2.1. Changes to the data model

No changes to the data model have been made.

1.2.2. Changes to definitions

The definitional changes to the 2023-24 specifications, compared to 2022-23 are listed in Table 1.1.

Table 1.1 Changes made to 2023-24 definitions compared to 2022-23

Data items	Details	Rationale
Person—marital status, code N	Updated Guide for use, Collection methods, Comments, and Reference documents.	Updated to clarify the value domain definitions and refer to the most recent ABS Family, Household and Income Unit Variables.
Residential mental health care NMDS 2023-24	Sex and Gender added to the list of glossary items.	These glossary items are included in the Person—sex, code X data element.

1.3. Reporting service provider entities

The reporting of service entities aims to create relationships between the mental health NMDSs, and where possible, the National Outcomes and Casemix Collection (NOCC), Local Hospital Networks/Public Hospital Establishments (PHE) NMDS and Admitted Patient Care (APC) NMDS (see Table 1.2).

The identifiers used in the RMHC NMDS are:

• State or territory (1 character)

• Region (2 characters)

• Specialised mental health service organisation (4 characters)

• Service unit cluster (5 characters)

• Service unit (6 characters)

Table 1.2 Reporting requirements for mental health and related NMDSs

Identifier element names	METEOR identifier	Community mental health care NMDS	Residential mental health care NMDS	Mental health establishments NMDS	Public hospital establishments NMDS	Admitted patient care NMDS
Australian State or Territory identifier	720081	Yes	Yes	Yes	Yes	Yes
Region identifier	269940	Yes	Yes	Yes	Yes	Yes
Specialised mental health service organisation identifier	404186	Yes	Yes	Yes	No	No
Hospital/Service unit cluster identifier	722233 (MHE) / 404858 (MHE, CMHC & RMHC)	Yes	Yes	Yes	Yes	Yes
Service unit identifier	721740 (MHE) / 750360 (MHE, CMHC) / 722711 (MHE, RMHC)	Yes	Yes	Yes	No	No

The use of identical identifiers between the various mental health data sets is tested via the Mental Health Establishments Skeleton file (SKL), handled by the Online Validator. The reports section of the RMHC submission will highlight any mismatches which should be rectified either through re-supply of the Skeleton file, or adjustment to the RMHC submission.

The following section explores in more detail the reporting levels used in the RMHC NMDS.

1.3.1. State or territory

This level refers to the state or territory and should be reported using the State/Territory identifier data element.

1.3.2. Region

The region refers to an administrative concept not a geographical one. States and territories may have one or more regions into which the state or territory is divided and to which its mental health service organisations belong. Region would be reported using the Region identifier (RegId) data element. In the smaller states or in the territories there may only be one or no region. In these cases, the Region identifier is to be reported as ‘00’ and the Region name (RegName) would repeat the name of the State or Territory.

1.3.3. Organisation

The organisation is defined according to the Object class Specialised mental health service organisation (METEOR identifier 286449) and reported using the Organisation Identifier (OrgId) data element. An organisation is a separately constituted specialised mental health service that is responsible for the clinical governance, administration and financial management of service units providing specialised mental health care. An organisation may consist of one or more service units based in different locations.

1.3.4. Service unit cluster

A specialised mental health service organisation may consist of one or more clusters of service units providing services in admitted patient, residential and/or ambulatory settings. For example, a specialised mental health service organisation may consist of several hospitals (clusters of admitted patient service units) and/or two or more ambulatory or residential service clusters (for example, a cluster of child and adolescent ambulatory service units, and a cluster of aged residential service units).

To allow service units (as defined below) to be reported individually, but still to be identified as part of a cluster, a separate reporting level has been created called ‘Service unit cluster’.

Residential service units will not necessarily belong to a ‘cluster’. However, groups of residential service units could be usefully reported as clusters. For example, clusters may exist of groups of residential services for aged persons in particular geographical areas. Where there is no service unit cluster then all service units within the organisation should be identified under a Service unit cluster identifier reported as ‘00000’ and the Service unit cluster name would use the relevant organisation name.

1.3.5. Service units

Service units in-scope for reporting to the RMHC NMDS must be identical to those reported to the MHE NMDS—that is, at a minimum disaggregated by operator (government-operated and non government operated), hours staffed (24-hour staffed and non-24-hour staffed), and Target population, even though hours staffed and target population are not reporting requirements for the RMHC NMDS.

1.3.6. Sector

Sector is not considered part of the identifier, however, within this NMDS, sector is an important attribute for each service unit.

1.3.7. Consistency of identifiers across reference periods

Where no major service reorganisations have occurred, the region, organisation, service unit cluster and service unit identifiers (RegId, OrgId, ClusId, SUId) used by a jurisdiction should be preferably identical to the previous year. However, given that all jurisdictions have committed to aligning ID numbers between the different NMDSs, changes in ID numbers due to this process will be accepted, as will be the case for those jurisdictions that have undergone significant reorganisation of service delivery that warrant new service entity identifiers. In these cases, jurisdictions should provide a supplementary mapping document that clearly illustrates the changes in ID numbers between collection periods, at all levels.

Region, organisation, service unit cluster and service unit name changes are acceptable, especially if the new name is more locally relevant. These will be identified as a change in the Online Validator, however will not affect the generation of the historical trends reports for RMHC in future.

1.4. Data model of the RMHC Extract

The basic design of the extract consists of a single data record for each Episode of residential care. Each Episode of residential care ‘belongs’ to a Person (the patient or consumer of services), who in turn is linked to a Residential mental health service unit (the provider of services), which may be linked to a Residential service unit cluster, which is linked to a Specialised mental health service organisation, which is linked to a Region which is linked to a State/Territory.

The structure of the data to be reported is represented in the data model shown in Fig. 1.1. In the model, a single Residential mental health service unit has associated records for one or more Persons, who each may have one or more Episodes of residential care. Each of the six data model building blocks (region, organisation, service unit cluster, service unit, person, episodes) has a unique set of attributes which comprise the NMDS data elements and additional supplementary information.

Two features of the model should be noted:

1. First, details of the residential service units reporting episode of residential care data are incorporated as part of the data extract, allowing linkage to related data sets provided by states and territories (in particular, the MHE NMDS).

2. Second, non-volatile person-level data in respect of patients (Date of Birth, Sex, Country of Birth, Indigenous Status) are separated from person-level data items that may change between episodes. This is designed to remove the redundancy that would occur if all patient-level data items were reported with each episode record and allow more straightforward counts/analysis at client level.

Fig. 1.1 Data model underlying the Residential Mental Health Care NMDS data extract

1.5. Data integrity

For cases of missing data (that is, unknown, not stated or not available):

• For Numeric [Num] fields, the data should be reported as zero, using leading zeros when necessary to pad out the field to the required length. The principle here is that all numeric fields require a valid value.

• For Text [Char] fields, the data should be space-filled to the required length. For single character fields where a ‘missing/not stated’ value has been specified for a particular data element (for example, ‘9’ has been specified for missing data), use the stated value for ‘missing/not stated’ rather than simply space filling.

Values in Date [Date] fields must be recorded in compliance with the standard format used across the National health data dictionary; specifically, dates must be of fixed 8 column width in the format DDMMYYYY, with leading zeros used when necessary to pad out a value. For instance, 13 March 2024 would appear as 13032024.

Values in Numeric [Num] fields must be zero-filled and right-justified. These should consist only of the numerals 0 to 9 and the decimal (‘.’) point if applicable to the data element.

Note: Fields defined as ‘Numeric’ are those that have numeric properties—that is, the values, for example, can be added or subtracted in a manner that is valid. Where a field uses numeric characters that do not have these properties (for example, the use of numbers for Patient identifier), the field is defined as ‘Character’.

Values in Character [Char] fields must be left justified and space-filled. These should consist of any of the printable ASCII character set (that is, excluding control codes such as newline, bell and linefeed).

1.6. Dataset specification (DSS)

The file structure for the transmission of data from jurisdictions to the AIHW is a single Fixed Format data file. The following tables specify the order in which the data items should be provided to the AIHW.

The extract format consists of a set of hierarchically ordered Data records, of which there are six types (see Table 1.3):

• Region details records

• Organisation details records

• Service unit cluster details records

• Service unit details records

• Person details records

• Episode of residential care details records

In each extract file for any given period, the Data records must be preceded by a single File Header Record having the structure outlined below in Table 1.4.

All records presented in the extract file should be grouped in the following order: Header Record, Region details records, Organisation details records, Service unit details records, Person details records, followed by Episode of residential care records.

With the exception of Region, Organisation and Service unit cluster details records, all Data records should include the following elements in the order shown:

• Record Type

• Establishment identifier (comprising: State/Territory identifier, Region identifier, Organisation identifier, Service unit cluster identifier and Service unit identifier)

• Specific data in the format specified for the given record type.

The order of fields in a record must be the same as the order they are specified in the Record Layouts below. Field values should be formatted as shown in the Record Layouts.

The first field in each record must be Record Type. Valid values are shown in Table 1.3.

Table 1.3 Valid values for Record Type

Record Type	Description
HR	File Header Record
REG	Region details records
ORG	Organisation details records
CLUS	Service unit cluster details records
SERV	Service unit details records
PER	Person details records
EPI	Episode of residential care details records

1.6.1. File header record

The first record of the extract file must be a File Header Record (Record Type = ‘HR’), and it must be the only such record in the file.

The File Header Record is a quality control mechanism, which uniquely identifies each file that is sent to the AIHW (that is, who sent the file, what date the file was sent, batch number of file, etc). The information contained in the header fields will be checked against the actual details of the file to ensure that the file received has not been corrupted.

The layout of the File Header Record is shown in Table 1.4.
