Queensland Perinatal Data Collection (QPDC):

For paper based forms:
Where the labour is interrupted (e.g. by caesarean section) and therefore either stage 1 and/or stage 2 are interrupted, complete as follows:
If stage 1 is complete and stage 2 is interrupted then report total length of stage 1 in hours and minutes and enter 'not completed' for stage 2.
If neither stage is compete then indicate by writing 'not completed' in both sections of the field.

Please note that if quantitative measurement has not been performed then clinical judgement based on subjective observation is appropriate (i.e. vaginal examination to confirm dilation is not mandatory). Use of other clinical observations used to manage labour are appropriate indications of stages of labour.

Where length of stages is unot known record 'unknown'.
