Study type
Description of intervention(s) / exposure
Intervention Group: Changed Room
In the intervention arm the bed will be pushed to the side of the room, the resuscitaire will be moved outside the room, birth mats, bean bags and birth balls will be placed in the centre of the room; music will be started; blinds will be closed; the door of the birth room will be closed and a ‘please knock & enter quietly’ sign displayed; lighting decreased and access to water encouraged.
The preparation of the room will take 5-10 minutes for the midwife to complete prior to the woman entering the room. Restrictions will not be placed on the woman; she should be facilitated to use any equipment (including the bed if she desires). If the circumstances of her labour change and access to the bed is required, (e.g. emergency instrumental delivery) health professionals will revert to the standard room. There will be no restrictions placed on minimum or maximum time spent in the room and will be at the discretion of the health professionals involved in the woman's care. Midwives will document room changes and adherence to intervention in both the routinely collected electronic medical records as well as on the Midwifery Survey which is completed by the midwife for each study participant.

Comparator / control treatment
Control Group: Standard Obstetric Room
Women randomised to the control arm will be assigned to a standard room (bed in the centre of the room, alternative birth equipment stored in a separate room, lights not dimmed). Women should not be prevented from utilising alternative birthing equipment if she desires.
Control group

Primary outcome [1] 322733 0
The primary outcome is mobility in labour as assessed by the study-specific 'Maternal Positions Form" which is contemporaneously completed by the midwife and documents predominant maternal position every 30 minutes and whether this position occurs on or off the bed.
Timepoint [1] 322733 0
Mobility of woman in active labour will be assessed contemporaneously. Birth Unit Midwives will be asked to complete a form documenting maternal position every 30 minutes and further information will also be gained by the completion of the postnatal survey by both the midwives and woman.

Key inclusion criteria
Inclusion/Exclusion Criteria
The National Midwifery Guidelines for Consultation and Referral (ACM 2015) provide information to midwives to assist with integrating evidence into their clinical care and to aid midwives in their discussions with women regarding different maternity care options. Pregnancy or medical conditions are labelled as either A, A*, B or C.
A or A*: Discuss the situation with a colleague, and/or medical practitioner. A* is the category for midwives endorsed to prescribe scheduled medicines and order diagnostic or screening tests (ACM, 2015, p.22).
B: Consult with a medical practitioner or other health care provider (ACM, 2015, p.22).
C: Refer a woman or her infant to a medical practitioner for secondary or tertiary care (ACM, 2015, p.22).
Inclusion Criteria
• 18 years or older at time of recruitment
• Experiencing a low-risk pregnancy and classified as either category A/A* or B under the National Midwifery Guidelines for Consultation and Referral (ACM 2015)
• Greater than 36 weeks gestation
• Planning a vaginal birth
Minimum age
18 Years
Maximum age
No limit
Can healthy volunteers participate?
Key exclusion criteria
Exclusion Criteria
• High-risk pregnancy classified as either category C under the National Midwifery Guidelines for Consultation and Referral (ACM 2015).
• If the woman is recruited while she is classified as low risk but during her pregnancy develops into a high-risk patient she will be excluded from the study.
• Medical indication requiring CS or other medical issues preventing upright positions in labour and birth
• Previous stillbirth or stillbirth in current pregnancy
• Inability to give informed consent.

Data analysis
The primary outcome measure is whether women mobilise or not (mean time spent upright) a two-sample T-test will be conducted to compare arms. The primary and secondary outcome measures will be assessed using descriptive and analytic statistics, odds ratios with 95% confidence intervals for categorical data, and mean +/- standard deviation, or mean and interquartile range for continuous variables. Intention to treat analysis will be undertaken.

Brief summary
The BED Study is a pilot randomised controlled trial to investigate whether physical changes to the Birth Unit room, increase mobility and upright positioning labour. Previous studies suggest that increased mobility decreases the use of pharmacological analgesia, decreases the length of labour, decreases the caesarean section rate, improves maternal satisfaction and therefore reduces length of hospital stay

In Auburn Hospital Birth Unit, standard room set up encourages women to immediately place themselves on the bed and stay there throughout their labour. This study will examine if a simple change to the physical set up of the room (moving the bed to the side of room) and placing alternative birth equipment (e.g. yoga balls and birth mats) will encourage women to mobilise during labour.

We will randomise 80 women to each arm of the study: standard birth room set up or alternate room set up without bed in central position. Data will be collected from a form that the primary midwife completes, the eMaternity database on length of labour, mobility during labour, pharmacological pain relief, caesarean section, length of hospital admissions and both the women and midwife caring for her in labour will also complete a short survey prior to discharge on the birth experience and satisfaction with the Birth Unit room.
