Congenital conditions - Guidance for notifiers

Explore the congenital condition data collected by the National Congenital Condition and Rare Disease Registration Service (NCARDRS) and guidance on how notifiers can submit data to the team.

Introduction

We collect information for cases booked in England for all pregnancy outcomes, for example pregnancy losses (all gestations), terminations of pregnancy (TOPS), stillbirths and live births. There is no limit on gestation or age. 

NDRS uses a comprehensive, multi-source approach to data collection to ensure that congenital conditions are identified as accurately and completely as possible. By bringing together information from a range of healthcare settings and data systems, we are able to build a robust national picture of these conditions and their outcomes.

When NHS teams suspect a physical condition, they share all scan reports with NDRS. This includes the initial scan report and any follow up fetal medicine scan reports with the outcome, including where the suspected condition is confirmed, changed or not present.


Congenital conditions we register

Congenital condition information we collect includes:

  • congenital conditions, (suspected or confirmed) – structural (excluding normal variants), genetic and chromosomal conditions and metabolic/biochemical disorders
  • enhanced data collection on NHS FASP physical conditions and trisomy 13, 18 & 21

For a full list of inclusions please refer to our inclusion list in the downloads section belowIf in doubt, please contact NCARDRS for advice or notify us. If a notification should be excluded, or is a duplicate, it will be deleted. The common antenatal and postnatal exclusions are listed below.

These are NCARDRS exclusions which may still need to be referred clinically as per local guidelines. Please refer to the Fetal Anomaly Screening Programme Handbook for more information.

Common prenatal exclusions (when isolated)

Enlarged nuchals (NTs or nuchal folds) of any size and cases of twin-to-twin transfusion without suspicion of further registerable condition.

Normal variants seen on ultrasound:

  • choroid plexus cysts
  • dilated cisterna magna
  • echogenic foci in the heart
  • two vessel cord
  • echogenic bowel
  • short femurs
  • renal pelvic dilation (RPD) if <10mm; (please notify RPD ≥ 10mm)
  • ventriculomegaly if < 10mm (please notify ventriculomegaly ≥ 10mm

Common postnatal exclusions (when isolated)

  • patent ductus arteriosus (PDA) or persistent foramen ovale (PFO) in preterm infants
  • right sided aortic arch
  • positional talipes
  • heart murmurs
  • clicky hips unless USS at 6 weeks confirms congenital hip dysplasia
  • Undescended testes
  • birth marks
  • accessory nipples
  • tongue tie
  • pyloric stenosis
  • sacral dimples - spina bifida occulta

General notification guidance

Please use the data collection form, in the guidance document section, for reporting suspected or confirmed congenital conditions (structural, chromosomal or biochemical).  This form should be used when congenital conditions are suspected or have been identified antenatally, during delivery or postnatally.

Please do not wait until final confirmation before sending this form. For suspected conditions, we may receive confirmation from another source, or we will obtain follow up information at a later stage.

We depend on multiple reporting mechanisms to achieve high case ascertainment so do not rely on someone else notifying us. If in doubt always complete a form and send it through to us. For pregnancies/births with multiple fetuses/babies with congenital conditions, please make sure it’s clear which fetus/baby the information relates to and complete one form per fetus/baby.

Please send us as much information as you have available, don’t worry if you can’t complete all the data fields. Please attach copies of any of the following to save time:

  • relevant ultrasound reports
  • clinic letters
  • laboratory reports
  • postmortem reports

If you are attaching any reports, you do not need to complete the results in the form as well. You need to have access to Adobe Acrobat Reader 9 or above. You can download it for free (you might need to ask for help from your IT department).

Save a blank copy of the form and use this each time you complete a new form (you can save a copy to your desktop). You can tab or mouse click through the fields to enter the information you have. After completion save a copy of it on a secure network directory for your information (you might want to label the file with the local Patient Identifier (PID) number.


Provider level guidance

When a physical condition is suspected, scan reports must be sent to NCARDRS in the following situations:

Table 1: District general hospitals

Data Type

Request

Electronic downloads covering all types of USS

If your site is notifying USS electronically no further spontaneous submissions required – any follow up data will be requested

Submitting notifications to NDRS

Notification checklist

Below are guidelines to support those completing NCARDRS notifications:

  1. Send notifications before final confirmation or outcome. 
  2. Send all 20-week screening scan reports with a suspected or unconfirmed finding for FASP auditable conditions or suspected/confirmed conditions where there is no referral to fetal medicine. 
  3. For twins/triplets, make sure it is clear which fetus has the condition.
  4. If you have a clinical report, such as an ultrasound scan report or a post-mortem, that contain the information you have you can send us a copy and you do not need to transcribe that information onto a notification form.
  5. If you prefer to use a notification form, please go to the download section below.

How to submit notifications

Where possible NCARDRS prefers to receive case notification in electronic data downloads. All notifications must be electronic and secure.

NCARDRS data collection portal

The secure NCARDRS data collection portal can be used - this contains a notification form and allows you to add six attachments per submission. 

If you are currently sending in PDFs/Excel files and would like to switch to bulk downloads or using the portal, please contact your regional NCARDRS office.

The regular Ultrasound Scan feed (USS), exported from Viewpoint or Astraia, can be submitted via the NCARDRS data collection portal. You can upload data for specific data feeds once your Trust has an account. Please contact the Data Liaison Manager, Helen Luff, if you require further information. 

Sending notifications and supporting documents via email

PDF notifications & reports and Excel files can be emailed to your NCARDRS regional office.

Please ensure PDF notifications are in a format where text can be copied - ideally as electronic PDFs, not image files. We recommend that you request delivery and read receipts. We will confirm receipt within three working days, via email.


Opting out of disease registration

Patients can opt out of disease registration if they do not want us to hold or use their data. 

Find out how patients can request to opt out of the disease registration process.

 Please send any feedback or queries to [email protected] or contact your regional NCARDRS office.
