The scope of the Mental health seclusion and restraint data set specification (SECREST DSS) is all specialised mental health public hospital acute service units. Short stay mental health units are in scope, e.g. Psychiatric Emergency Care Centres.

Wards or units other than specialised mental health services, such as emergency departments, are out of scope.

Specialised mental health acute forensic hospital services are in scope, regardless of which department manages the service, for example health versus correctional services department.

Physical and mechanical restraint are in scope for this collection. While chemical/pharmacological restraint is defined in some jurisdictional Mental Health Acts, issues around definitions and collection preclude nationally comparable data supply activities for this category of restraint. Therefore, chemical/pharmacological restraint is out of scope for the purposes of data collection for the SECREST DSS.

Metadata items in this Data Set Specification

Below is a list of all the components within this Dataset Specification.
Each entry includes the item name, whether the item is optional, mandatory or conditional and the maximum times the item can occur in a dataset.
If the items must occur in a particular order in the dataset, the sequence number is included before the item name.

Data Elements
Reference Data Element Data Type Length Inclusion #
Address—statistical area, level 2 (SA2) code (ASGS 2011) N(9) - - mandatory 1
Establishment—accrued mental health care days, total N[N(7)]
Specific Information:
Jurisdictions should note that this data element is used to be consistent with the Mental health establishments NMDS and allow the population of MHS PI 15: Rate of seclusion. However, the figures reported against accrued mental health care days for the purposes of the SECREST DSS should be calculated and supplied using the same methodology as previous Seclusion ad hoc submissions. This means that if data were previously supplied using an occupied bed days methodology, the data provider should continue supplying figures consistent with this methodology.
- - mandatory 1



This DSS is likely to undergo continuous enhancements as data definitions and information systems are developed that improve the availability of information for collection at lower levels of analysis (e.g. separation, seclusion/restraint event and person level data).
