Study title: The OptiBreech Care Trial: a small randomised trial to determine whether a large trial is possible for women with a breech-presenting baby at term

version 1.1, 31 October 2021, IRAS: 303028

Chief Investigator / Project Lead:  Dr Shawn Walker, King’s College London,

Invitation and brief summary

We would like to invite you to participate in this research project. You are being invited to participate in this project because your baby is breech (bottom-down, rather than head-down) at the end of pregnancy, and you were planning a vaginal birth.

Before you decide whether you want to take part, it is important for you to understand why the research is being done and what your participation will involve. Please take time to read the following information carefully and discuss it with others if you wish. Please ask if there is anything that is not clear or if you would like more information.

What is the purpose?

We are conducting a small initial study to see if a larger study is possible.

The ultimate purpose of this study is to identify outcomes for women and birthing people carrying a breech baby at term. Some women choose to try to turn the baby head-down. Some women choose to plan a vaginal breech birth. And some women choose to plan a caesarean section. Women have told us they would like more up-to-date information about the relative safety and effectiveness of each of these options. So we would like to understand more about how each of these choices compare in contemporary maternity services.

We would also like to offer some new methods that have shown promise in potentially improving outcomes for women and their breech babies at term. This could be at any point in the care pathway, such as changes to improve the success rates of turning babies head-down, improve the safety of vaginal breech birth or improve the experience of breech caesarean sections. To test these new methods, we would like to allocate eligible women already participating in the study by chance to be offered a new care process, or not. This allocation by chance is called ‘randomisation,’ and it enables us to be sure that any differences in results are due to the effects of the new care process and not other reasons.

What would taking part involve?

If you choose to participate in this study, we will ask you for consent:

To access your medical records and those of your baby, so that we can record information about the health services you use and the outcomes of your birth;
To be allocated by chance to be offered a new treatment, or not, if eligible (randomisation);
To send you follow up surveys at 1 month, 3 months, 1 year and 2 years;
To allow us to collect follow-up information on you and your baby, from hospital and community records, for a period of up to 10 years after your birth.

Examples of information we may obtain from your health records include: what kind of birth you had (e.g. vaginal birth or caesarean birth), whether your baby needed any additional care following the birth, how many total appointments you had with healthcare professionals during and after your pregnancy.

You can agree to all of the part of this study, or only the portions you feel comfortable with.

What if I am not eligible or choose not to be allocated by chance?

If your pregnancy has additional complexities, you may not be eligible to be allocated by chance to be offered a new treatment. Or you may prefer not to be. Or the hospital where you are receiving care may not yet be participating in the randomised portion of this research. You can still participate in the observational portion of the study. This is very helpful because it allows us to collect larger amounts of data in order to understand outcomes that happen much more rarely.

In this case, you would receive standard care according to your hospital’s guideline.

What will happen if I am randomised?

If you are eligible for randomisation and have consented to this, a health care professional will allocate you by chance to either

Standard care – You will receive care as usual and no further consent is required. Your data will be compared to the data from women who have been allocated by chance to be offered a new treatment.

New care process – You will be offered a new care process. The potential benefits and risks of this new care process will be explained to you. You will decide if you would like to accept it, and we may ask you to sign another consent form if you do. Your data will be compared with women who were not offered the new care process.

What if I change my mind?

Your choice of treatment is ALWAYS your own. If you are allocated one treatment but upon reflection wish to decline this, you will be supported whichever decision you decide to make.

Data about health service use

In this study, we will collect data about your use of health services during your breech pregnancy. This will include a hand-held record, in which you and your health care providers will record all of your appointments related to your breech pregnancy. This data will help us to determine what it costs to provide different types of care.

Surveys and longer-term follow-up

If you participate in the study in any way, we will send you a link to a follow-up survey by e-mail at 1 month, between 3 and 4 months and at 1 and 2 years after you have given birth. This surveys will ask you questions about your experience of care, about you and your baby’s use of health services since the birth and about your baby’s development. You are under no obligation to continue to participate if you no longer wish to.

The women who contributed to the design of this research indicated that it was important to them to know about the long-term outcomes associated with their birth choices. Therefore, we would like permission to collect information on your health service usage and outcomes, for you and your baby, including from hospital and community health records, for a period of up to 10 years. For example, we may access your baby’s health records to determine how many hospital admissions they have had following their birth in breech position. Our follow-up will include information on the outcomes of subsequent pregnancies, as these are often affected by the previous births. If we continue to collect data after 2 years, this will be subject to additional ethics approvals.


This follow-up will require us to maintain your contact information and NHS numbers, for you and your child. We will also inform your GP about your participation in this study if you give us permission to do this. However, all of your personal information will be kept in a separate secure location from the data we are collecting.

When you enter the study, you will be allocated a code. This will be linked to your personal information and enable you to access the surveys. But when the researchers analyse the information we have collected, your personal details will not be included. Only the Project Lead and Manager will have access to your personal details, and we will only access them if we need to contact you, or to communicate with your health care service providers in order to collect the data.

Do I have to take part?

Participation is completely voluntary. You should only take part if you want to and only the parts that you feel comfortable with. You may choose to share your data about birth outcomes but not participate in surveys or long-term follow-up if contacted. Choosing not to take part will not disadvantage you in anyway.

Once you have read the information sheet, please contact us if you have any questions that will help you make a decision about taking part. If you decide to take part we will ask you to sign a consent form and you will be given a copy of this consent form to keep.

What are the possible benefits of taking part?

Previous studies have shown that participation in clinical trials improves outcomes in women’s health compared to non-participation, regarless of whether you are allocated to the new treatment arm or not. The new treatments we are testing are only available through participation in the study, where they are not already part of the hospital’s guideline.

What are the possible disadvantages and risks of taking part?

Keeping a record of your appointments and completing follow-up surveys may be time-consuming. The new treatments we are testing may be effective, they may not result in any improvement, or they may introduce new risks we had not anticipated. This study is overseen by a Trial Steering Committee, to whom all serious adverse outcomes are reported and who have the power to stop the trial if the treatments appear to be less effective or to carry additional risk part way through the trial.

How is the project being funded and organised?

This project is being funded by the National Institute for Health Research (NIHR). King’s College London is organising the study.

Who else has reviewed the study?

The study has been reviewed by the West London Research Ethics Committee (21/LO/0808).

What will happen to the results of the study?

The results of the project will be submitted for publication. The information reported will not contain any details that would enable you to be identified by someone reading the report. A summary will be posted on the feasibility study’s website:

Involvement of service users in the research

A Patient and Public Involvement (PPI) group has been involved in designing this research, this information and the consent form. If you would like to become a part of this PPI group after you give birth, you can find more information on the study’s website:

The PPI group has also created a private FaceBook group for participants in the study, to enable service users to share experiences and support each other. This can be accessed here:

Information on the Use of Data

How will we use information about you? 

We will need to use information from you and your medical records for this research project. 

This information will include your NHS number, name and contact details. People will use this information to do the research or to check your records to make sure that the research is being done properly.

We will keep all information about you safe and secure, in a separate place from the data we are analysing. 

Once we have finished the study, we will keep some of the data so we can check the results. We will write our reports in a way that nobody can work out that you took part in the study.

What are your choices about how your information is used?

You can stop being part of the study at any time (withdraw), without giving a reason, but we will keep information about you that we already have.

We need to manage your records in specific ways for the research to be reliable. This means that we won’t be able to let you see or change the data we hold about you.

If you agree to take part in this study, you will have the option to take part in future research using your data saved from this study. This will be stored on the secure KCL network drive.
