Brief summary
This randomized clinical trial will examine if there are any differences between post-dates inductions (inductions after 40 weeks of pregnancy) begun in the morning compared to the evening for first-time mothers. Sleep and fatigue measures will be measured to see if they differ by time of induction. Other measures will include the rate of births within 24 hours of admission, length of labor, use of labor analgesics, and method of delivery.
Detailed description
Randomized clinical trial of first-time pregnant women requiring post-dates induction (induction after 40 weeks gestation). Women will be randomized to a labor induction time in the morning or the evening. On hospital admission once women have signed the study consent, they will complete sleep questionnaires and a fatigue assessment. Fatigue and sleep time assessments will subsequently done by the study subject every 4 hours until women enter active labor. At the onset of active labor, assessments will stop. Labor outcomes and patient satisfaction will be obtained once women deliver.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Birth within 24 hours of induction | Day 1 | Calculate proportion of women delivering within 24 hours of the start of labor induction between the two groups |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in fatigue scores | Day 1 | Differences in Fatigue Visual Analog Scales from admission to active labor between the two groups. |
| Change in hand grip strength | Day 1 | Differences in change in hand grip strength from admission to active labor between the two groups. |
| St. Mary's Sleep scale | Prebaseline: Baseline - 12-24 hours | Differences in St. Mary's Sleep scores on admission between the two groups. |
| Labor and birth satisfaction | Day 2 | Differences in Labor and Birth Satisfaction between the two groups. |
| Cesarean rate | Day 1 | Compare cesarean rates between the two groups |
| Sleep Quality | Prebaseline: Baseline - 30 days | Correlation between sleep quality in the one month prior to admission measured with the Pittsburgh Sleep Quality Index and birth within 24 hours of start of induction. |
| Length of time to labor intervention | Day 1 | Measure differences between groups between length of time from admission to different labor interventions e.g., rupture of membranes, analgesia - IV or epidural |
| Neonatal outcomes | Day 1 | Differences between groups on neonatal outcomes such as 5 minute Apgar scores and admission to neonatal intensive care unit. |
| Morning-evening chronotype | Day 1 | Correlation between Horne-Osteberg Morning-Eveningness chronotype and birth within 24 hours of start of induction. |
