There are plans to link with the National Death Index (NDI) and date based admitted episodes data sets.







Number of individuals/ episodes of care included in the registry

2059 Individuals 

Date in which this was determined


Example of data collection questionnaire

Data dictionary

Data linkage


If nationally approved codes are used to identify the subject, clinician or institution, what is link key?

Medicare number

To which other database is linkage routinely undertaken

Links to the NDI are planned once the registry is funded and fully operational



Where are the electronic data held?

Computer networked to and internal network: Data help on computer which is networked within the institution and backed up onto a server.

Subjects informed individually of data collection and use to which data will be put 





How frequently are data transferred from the health care providers to the central database?

Weekly (Once the web system if fully operational. It is expected that the sites will enter data on a daily/weekly basis)

Can ad hoc analyses be preformed for health care providers?

Locally: Yes (planned feature)

Centrally: Yes (planned feature)

Audit reports


How frequently are multi-centre audit reports produced?

No reports have been produced.

How frequently are provider-specific audit reports produced?

Audits are planned and will be carried out annually


No publications to date




Is the registry approved by any clinical/professional association?

How often does the Management Committee meet?

Monthly (planned)



What is the source of funding for the registry?

Which group/s, if any, should be represented but is/are not?


Completeness of recruitment of eligible population

The proportion of the eligible population that the registry includes

All hospitals performing cardiac procedures in Australia.

How and when was completeness last determined?

Unknown at this point as no checking/audit of the pilot data has been undertaken. Planned to be checked via linkage with admitted episodes data sets.

Date in which last preformed




What variables are included in the registry

Identifier, Admin information, Condition, Intervention, Short term outcome, Major unknown confounders, Long term outcomes ( 12 month follow up is planned once the registry is funded and fully operational beyond the pilot.

Completeness of data


The percentage of variables at least 95% complete

Level 4: All or almost all (>97%)

When was the completeness last determined?

The web system has been built to only allow data to be submitted if a valid value is entered of notes support a null value. A formal analysis of the pilot has not been completed to data.

Continuous data


The percentage of continuous variables collected as rave data 

Level 4: All or almost all (>97%)

Use of explicit definitions for variables

The percentage of variables which have clear definitions laid out in a document such as a data manual

Level 4: All or almost all (>97%)

Use of explicit rules for deciding how variables are recorded

The percentage of variables which have clear rules on how to code them in the registry laid out in a document such as a data manual

Level 4: All or almost all (>97%)

Reliability of coding

How standardised is the coding for conditions and interventions? 

Level 1: Not tested. No intra-rater reliability test conducted.

How and when last tested


Independence of observations of primary outcomes

What outcome/s do/does the registries collect?

Primary outcome of interest collected by the registry: Mortality – see attached key performance indicators for each mortality process for the full list of KPI’s/ outcomes.

Data Validation

What measures are taken to ensure that the data are valid
