Collection and Usage Attributes
Guide for Use
For live births, birthweight should preferably be measured within the first hour of life before significant postnatal weight loss has occurred. While statistical tabulations include 500g groupings for birthweight, weights should not be recorded in those groupings. The actual weight should be recorded to the degree of accuracy to which it is measured.

In perinatal collections the birthweight is to be provided for liveborn and stillborn babies.

Weight on the date the infant is admitted should be recorded if the weight is less than or equal to 9000g and age is less than 365 days.

If birth weight is not available, record first available weight.
Verification Rules
Queensland Perinatal Data Collection (QPDC):
If born alive = 2 (Stillborn), baby must be  >= 400 grams if gestation <20 weeks. 
Must not be blank.
Right adjusted and zero filled from left.
Collection Methods
Queensland Perinatal Data Collection (QPDC):
If the baby was a stillbirth, the birthweight must be >=400 grams or the gestation at least 20 weeks to be within the scope of the collection. If a stillbirth was less than 20 weeks gestation and less than 400 grams, then the baby is not in scope for the perinatal database. All livebirths are within scope, regardless of weight or gestation.
