Nuchal Translucency Quality Assurance

Important information about nuchal translucency quality assurance (NTQA) in Ontario:

Nuchal translucency (NT) has been a part of Prenatal Screening in Ontario since 2001, and sonographers have played a huge role in providing the majority of pregnant persons with excellent quality risk prediction for Down syndrome.

Both internationally and nationally, authorities have recommended that anyone providing NT measurements be part of a formal NTQA program, as it has been noted that without it, measurement quality and therefore quality of screening deteriorates over time. Many Ontario sonographers have not been part of any internationally recognized QA programs (eg. the Fetal Medicine Foundation UK) after initial certification.

Although we have been able to centrally track measurement data on all registered Ontario sonographers, to date we have not had the capacity to provide any feedback on that information.
BORN Ontario has developed a Nuchal Translucency Quality Assurance (NTQA) audit curve. With the launch of  Prenatal Screening Ontario (PSO), we are preparing to communicate further with individual sonographers and their supervising physicians to provide continuing updates and to open a dialogue about the program and future NTQA requirements for ultrasound practitioners.

All sonographers and physicians who provide NT measurements for prenatal screening are being asked to register with BORN and Prenatal Screening Ontario, and to access their NTQA audit curve. Registration will require providing up to date contact information so that PSO can provide important information regarding NTQA in the province (please see IMPORTANT INFORMATION below for a link to register for a BORN login ID). All future communications regarding NTQA will occur via the email in your BORN profile. If you are already registered with BORN, please update your contact information no later than April 1, 2019. Failure to provide updated contact information may result in missing communications pertaining to mandatory NTQA requirements, and can result in suspension or loss of NT ID number.
