Plain English Summary
Current plain English summary as of 18/09/2020:
Background and study aims
Miscarriage is a term given to the loss of a baby during the first 23 weeks of pregnancy. Some women experience recurrent miscarriage, in which they experience three or more miscarriages in a row. Recurrent miscarriage is a distressing problem for which there is no effective preventative treatment currently. In order to develop new treatments, we need to identify couples at high risk of future pregnancy loss. There is little evidence that assesses the predictive power of current tests and risk factors, such as pregnancy loss history and body mass index (BMI). There have been very few long-term follow-up studies with accurate recording of future pregnancy outcomes. This study is using digital technology to collect and analyse information about the patient’s history and investigation results and link these to pregnancy and neonatal outcome. The aim of this study is to undertake a large study of pregnancy outcome following miscarriage.
Who can participate?
Couples who have suffered miscarriage.
What does the study involve?
After agreeing to take part, women and their partners are asked to complete a questionnaire about their previous experiences with pregnancy loss and have their medical records reviewed to find out about their medical history. Every 6 months, couples are asked to fill in questionnaires about whether they have had any reproductive treatment and if that has led to a successful pregnancy and birth. Information collected in this study is then used to identify couples at risk of pregnancy loss and to predict pregnancy outcomes.
Participants will also be offered the opportunity to give their consent to take part in future Cohort Multiple Randomised Controlled Trials (cmRCT). Participants will agree to participate in the control (no treatment) arm of any future trials that will be conducted by the research team. If the participant is allocated to the intervention group of a future trial, they will be asked to provide their consent prior to taking the intervention.
What are the possible benefits and risks of participating?
There are no direct benefits or risks involved with participating in this study.
Where is the study run from?
1. University Hospitals Coventry and Warwickshire NHS Trust (UK)
2. Birmingham Women's Hospital Foundation Trust (UK)
3. Imperial College Healthcare NHS Trust (UK)
When is the study starting and how long is it expected to run for?
April 2016 to April 2026
Who is funding the study?
Tommy’s Baby Charity (UK)
Who is the main contact?
Professor Siobhan Quenby

What does the study involve?
After agreeing to take part, women and their partners are asked to complete a questionnaire about their previous experiences with pregnancy loss and have their medical records reviewed to find out about their medical history.

| Condition | Miscarriage |
| Intervention | Couples will be asked to fill in clinical history sheets prior to clinic visits. When they arrive at the clinic a member of the research team will explain Tommy’s Net and ask them to consent to the study. If they consent they will be asked permission to have their data entered into a bespoke server and database. This system will then also import results of investigations and reproductive outcomes. Couples will be contacted every 6 months for details of further reproductive treatment and pregnancy outcomes. The baby’s NHS number will be requested through appropriate consent so that follow up of the baby’s development could be facilitated. Information regarding the babies developmental follow up will be requested from GP records using data linkage. |
| Intervention type | Other |
| Primary outcome measure | Live birth rate is assessed by patient questionnaire and data linkage at 6-month intervals until family is complete and child is aged 5 years. |
| Secondary outcome measures | 1. Miscarriage rate is assessed by patient questionnaire and data linkage at 6-month intervals until family is complete 2. Type of miscarriage is assessed by patient questionnaire and data linkage at 6-month intervals until family is complete 3. Obstetric complications are assessed by patient questionnaire and data linkage at 6-month intervals until family is complete 4. Neonatal complications are assessed by patient questionnaire and data linkage at 6-month intervals until family is complete |
