Collection and Usage Attributes
Guide for Use 
Labour commences at the onset of regular uterine contractions, which act to produce progressive cervical dilatation, and is distinct from spurious labour or pre-labour rupture of membranes.

If prostaglandins were given to induce labour and there is no resulting labour until after 24 hours, then code the onset of labour as spontaneous.

Code 1 Spontaneous
Labour commences at the onset of regular uterine contractions, which act to produce progressive cervical dilatation, and is distinct from spurious labour or spontaneous pre-labour rupture of membranes.

Code 2 Induced
Medical and/or surgical procedure performed for the purpose of stimulating and establishing labour in a woman who has not commenced labour spontaneously.

Code 3 No labour
Indicates the absence of labour, as in a caesarean section performed before the onset of labour or a failed induction.

Code 9 Not stated/inadequately described
Onset of labour is not known.
Verification Rules 
Queensland Perinatal Data Collection (QPDC):
Must not be blank.
Validated against list of onset of labour codes.

Perinatal National Minimum Data Set (NMDS):
This data element should be recorded in conjunction with the data element Birth event-labour induction method (NHDD) when the labour onset type is code 2 (Induced).

This data element should be recorded in conjunction with the Birth event-analgesia administered indicator (NHDD) data element when labour onset type is code 1 (Spontaneous) or code 2 (Induced).

This data element should be recorded in conjunction with the Birth event-type of analgesia administered (NHDD) data element when labour onset type is code 1 (Spontaneous) or code 2 (Induced) and the Birth event-analgesia administered indicator (NHDD) data element is code 1 (Yes).

This data element should be recorded in conjunction with the Birth event-main indication for induction of labour (NHDD) data element when labour onset type is code 2 (Induced).

This data element should be recorded in conjunction with the Birth event-additional indication for induction of labour (NHDD) data element when labour onset type is code 2 (Induced), the Birth event-main indication for induction of labour (NHDD) data element is completed, and there is more than one reason for which an induction was performed.

Comment
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.
