Scope:Help on this term

The scope of the Perinatal national best endeavours data set (NBEDS) is all births in Australia in hospitals, birth centres and the community. The data set includes information on all births, both live births and stillbirths, of at least 20 weeks gestation or 400 grams birthweight.

These data have two dimensions, which are the baby and the mother. All data relevant to the birth are conveyed in relation to one of these.

Collection and usage attributes

Statistical unit:Help on this term

As there are two dimensions to the data, there are two statistical units:
1. Mother (Female)
2. Baby (Product of birth)

Guide for use:Help on this term

This NBEDS is intended as an interim standard only. If jurisdictions are able to report the data elements then they should do so. It is expected that the data elements will be included as mandatory data elements in future Perinatal national minimum data sets (NMDS).

Collection methods:Help on this term

National reporting arrangements:

State and territory health authorities provide the data to the Australian Institute of Health and Welfare for national collation, on an annual basis.

Periods for which data are collected:

Financial year ending 30 June each year.

DSS specific information:

This is a multiple response data element and is therefore operationalised for data collection across 3 individual data items (one data item per permissible value, excluding Code 99 (Not stated/inadequately described)).

Conditional3
-Female—type of hypertensive disorder during pregnancy, code N

Conditional3
-Person—family violence screening status, code NMandatory1
-Person—height (measured), total centimetres NN[N].N

DSS specific information:

It is acceptable for measured height to be rounded to the nearest centimetre.

It is preferable to collect and record a pregnant female's height as a measured height. Where a measured height has not been provided or it is not possible to ascertain whether the height has been measured or self-reported, the value 999.9 should be recorded against this data element. Data should then be recorded against the Person—height (self-reported), total centimetres NN[N] data element.

-Person—height (self-reported), total centimetres NN[N]

Conditional obligation:

It is preferable to collect and record a pregnant female's height as a measured height. Where a measured height has not been provided or it is not possible to ascertain whether the height has been measured or self-reported, the value 999.9 should be recorded against the Person—height (measured), total centimetres NN[N].N data element. Data should then be recorded against this conditional self-reported height data element.

DSS specific information:

It is acceptable for a self-reported height to be rounded to the nearest whole centimetre.

Conditional1
-Person—presence or history of mental health condition indicator, yes/no/not stated/inadequately described code NMandatory1
-Person—weight (measured), total kilograms N[NN].N

DSS specific information:

Weight rounded to the nearest whole kilogram is acceptable.

Weight should be recorded in the first trimester, preferably as a measured weight. However, the female's self-reported weight around the time of conception is acceptable if a measured weight is not available.

It is preferable to collect and record a pregnant female's weight as a measured weight. Where a measured weight has not been provided or it is not possible to ascertain whether the weight has been measured or self-reported, the value 999.9 should be recorded against this data element. Data should then be recorded against the Person—weight (self-reported), total kilograms NN[N] data element.

-Person—weight (self-reported), total kilograms NN[N]

Conditional obligation:

It is preferable to collect and record a pregnant female's weight as a measured weight. Where a measured weight has not been provided or it is not possible to ascertain whether the weight has been measured or self-reported, the value 999.9 should be recorded against the Person—weight (measured), total kilograms N[NN].N data element. Data should then be recorded against this conditional self-reported weight data element.

DSS specific information:

Weight rounded to the nearest whole kilogram is acceptable.

Weight should be recorded in the first trimester, preferably as a measured weight. However, the female's self-reported weight around the time of conception is acceptable if a measured weight is not available.

Conditional1
-Product of birth—head circumference, total centimetres NN[N].N

DSS specific information:

Baby head circumference can be recorded as measured e.g. 35.1 cm or can be rounded to the nearest 0.5 cm, e.g. 35.0 cm, but in any case measurement should be recorded at least to the nearest 0.5 cm.

If rounding, round up or down to the nearest 0.5 cm, e.g. 35.2 cm would be rounded down to 35.0 cm; 35.3 cm would be rounded up to 35.5 cm.

Example:

A baby has two head circumference measurements taken at birth of 34.2 cm and 34.6 cm. These are within 0.5 cm of each other so the higher measurement of 34.6 cm is the correct one to record. It can be recorded as 34.6 cm or rounded to the nearest 0.5 cm, that is, 34.5 cm.
