The main reason for induction of labour should be the reason that the clinician attending the birth believes to be the main reason for the induction of labour being performed. It should be determined at the time of induction and not revised later or selected based on information that becomes available after delivery.
Indications for induction are conditional on an induction being performed. Indications for induction are completed after the Birth event-labour onset type has been coded as: 2 Induced.
