Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The study will be based in the United Kingdom (UK), at the Maternity Unit of a District General Hospital, and will be carried out over 12-18 months.
A group of babies whose mothers took SSRIs whilst pregnant will have an Electrocardiogram (ECG) done when they are 2-3 days old. These will be compared with babies whose mothers did not, but whose babies were still in hospital because they were at risk of having an infection, but were found to be healthy.
The study hopes to see whether there is a link between SSRI use in pregnancy and lengthening of the QT interval and if so, extra surveillance may be considered for this group of babies.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Currently it is standard practice for a plan of care for after the baby is born (an ALERT) to be generated whilst the woman is pregnant. The ALERT form is developed by specialist nurses, Advanced Neonatal Nurse Practitioners (ANNPs) and Doctors specialising in newborn babies. The ALERT form details the recommended place of birth; length of expected hospital stay; known side effects of SSRIs; the monitoring that is done after birth and why; and whether breastfeeding is advised. This is returned to community midwifery staff to discuss with the woman ahead of delivery. When the woman who has taken SSRIs in her pregnancy comes to the maternity unit to deliver the ALERT form is activated. After birth she will be assessed by maternity staff and ANNPs to see if her baby is suitable for the study, and if so, she will be given an information leaflet and invitation letter when her baby is 12 hours old by these staff.
The other group of mothers that will be asked for the participation of their babies, will be those who require treatment with intravenous antibiotics for at least 36 hours, having been identified as being at risk of having an infection within 12 hours of being born. An infection marker, C-Reactive Protein (CRP) in their blood is measured, and if this remains normal after 18 hours and the baby is suitable for the study, the mother will be given an information leaflet and invitation letter by maternity staff/ ANNPs. Antibiotics will continue to be given to the baby for at least 36- 47 hours until a blood test shows whether they have an infection or not. If they don't have an infection and are healthy, they will be considered for this study.
Both groups of babies are regularly monitored by the staff in the maternity unit to make sure that any problems they have are acted on quickly. Both groups of babies would normally be in hospital for 36- 48 hours for this monitoring.
When the babies in both groups are 48-72 hours old, the ANNPs will ask the mother if she is happy for her baby to have an electrocardiogram (ECG) to look at their heart beat pattern. After consideration time, a consent form is signed, a data collection sheet completed, and the ECG is carried out on the baby. This will happen on the ward so there is minimal disruption to the mother and baby.
The ECG machine used is very accurate so if it shows the heart beat pattern is normal, the parents are told the result and can go home. The ANNPs and Doctors specialising in the care of newborn babies will check the result within 24 hours.
If the ECG machine says the heart beat pattern is not normal, then the baby remains in hospital, whilst the result is checked by the ANNPs and the Doctors specialising in the care of newborn babies, as soon as possible after it is taken. If the heart beat reading is abnormal, the ANNPs and Doctors specialising in the care of newborn babies will talk to the parents about further tests and other monitoring.
If the confirmed ECG result is known before discharge home, the General Practitioner (GP) / Community staff will be told of the study and the result, on the hospital discharge letter the mother takes home for them. If the family have gone home before this happens they will receive a confirmed normal result in the post. The confirmed result will also be added to the electronic hospital records.
In order to give statistically significant results, the study will be carried out over 12 -18 months, and involve 121 babies in each group. After 50 babies have had an ECG, the results will be reviewed to see what results are being seen and to see if the study is following the original plan/ time frame.
A statistician helped to determine how many babies would be needed for the study to show a difference between the two groups. However even if the difference is less than expected, the study may still point to the possibility of an association and provide useful data for future studies.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Neonates exposed to AN SSRI use
A group of newborn babies who have been exposed to SSRIs in pregnancy will receive an Electrocardiogram at 48-72 hours of age.
Electrocardiogram
The ECG is a non-invasive screening tool. It will be performed when the neonate is settled and comfortable. The electrodes used are made with soft jelly adhesive which is stored at room temperature. The procedure will be conducted in a timely manner, taking no longer than 15 minutes. The electrodes are easily removed, and the neonate redressed.
Neonates not exposed to AN SSRI use
A group of newborn babies, who require treatment with intravenous antibiotics for at least 36 hours, having been identified as being at risk of having an infection within 12 hours of being born. They are subsequently confirmed as clinically well and will receive an Electrocardiogram at 48-72 hours of age.
Electrocardiogram
The ECG is a non-invasive screening tool. It will be performed when the neonate is settled and comfortable. The electrodes used are made with soft jelly adhesive which is stored at room temperature. The procedure will be conducted in a timely manner, taking no longer than 15 minutes. The electrodes are easily removed, and the neonate redressed.
