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.
| Reference | Data Element | Data Type | Length | Inclusion | # |
|---|---|---|---|---|---|
| Birth event—birth method, code N | Number | 1 | mandatory | 1 | |
| Birth event—birth plurality, code N | Number | 1 | mandatory | 1 | |
| Birth event—birth presentation, code N | Number | 1 | mandatory | 1 | |
|
Birth event—labour onset type, code N
Specific Information:
How labour commenced is closely associated with method of birth and maternal and neonatal morbidity. Induction rates vary for maternal risk factors and obstetric complications and are important indicators of obstetric intervention. |
Number | 1 | mandatory | 1 | |
|
Birth event—setting of birth (actual), code N
Specific Information:
Used to analyse the risk factors and outcomes by place of birth. While most deliveries occur within hospitals, an increasing number of births now occur in other settings. It is important to monitor the births occurring outside hospitals and to ascertain whether or not the actual place of delivery was planned. |
Number | 1 | mandatory | 1 | |
| Birth event—state/territory of birth, code N | - | - | mandatory | 1 | |
|
Birth—Apgar score (at 5 minutes), code NN
Specific Information:
Required to analyse pregnancy outcome, particularly after complications of pregnancy, labour and birth. The Apgar score is an indicator of the health of a baby. |
String | 2 | mandatory | 1 | |
| Birth—birth order, code N | Number | 1 | mandatory | 1 | |
|
Birth—birth status, code N
Specific Information:
Essential to analyse outcome of pregnancy. |
Number | 1 | mandatory | 1 | |
|
Birth—birth weight, total grams NNNN
Specific Information:
For the provision of state and territory hospital data to Commonwealth agencies this metadata item must be consistent with diagnoses and procedure codes for valid grouping. Weight is an important indicator of pregnancy outcome, is a major risk factor for neonatal morbidity and mortality and is required to analyse perinatal services for high-risk infants. This metadata item is required to generate Australian National Diagnosis Related Groups. |

Episode of admitted patient care—separation date, DDMMYYYY
Specific Information:
For the provision of state and territory hospital data to Commonwealth agencies this field must:
|
Date/Time | 8 | mandatory | 1 | |
| Establishment—organisation identifier (Australian), NNX[X]NNNNN | - | - | mandatory | 1 | |
|
Female (pregnant)—estimated gestational age, total weeks NN
Specific Information:
The first day of the last menstrual period (LMP) is required to estimate gestational age, which is a key outcome of pregnancy and an important risk factor for neonatal outcomes. Although the date of the LMP may not be known, or may sometimes be erroneous, estimation of gestational age based on clinical assessment may also be inaccurate. Both methods of assessing gestational age are required for analysis of outcomes. |
String | 2 | mandatory | 1 | |
| Person—area of usual residence, geographical location code (ASGC 2007) NNNNN | - | - | mandatory | 1 | |
| Person—country of birth, code (SACC 1998) NNNN | - | - | mandatory | 1 | |
