Additional information about PSO and NTQA

Prenatal Screening Ontario (PSO), a program housed within BORN Ontario, has been given the mandate to coordinate prenatal screening in the province including the quality assurance of nuchal translucency ultrasound and first trimester screening.

Guided by BORN Ontario data and a panel of experts in diagnostic imaging and prenatal screening, PSO is implementing a nuchal translucency quality assurance (NTQA) program for the province.

Since the incorporation of the NT measurement into the prenatal screening process, sonographers have played a huge role in providing the majority of pregnant persons with excellent quality risk prediction for Trisomy 21 (Down syndrome) and Trisomy 18 (Edwards syndrome). Professional bodies recommend that sonographers participate in a formal NTQA program if taking NT measurements. Without participation in such a program, measurement quality and screening quality deteriorates over time.

The goal of PSO's NTQA program is to support sonographers in their practice by assessing their NT measurement performance and providing them with actionable feedback to help them improve and/or maintain their skills.

All sonographers who provide, or who wish to provide NT measurements to the Ontario MMS labs for first trimester screening must register with PSO at BORN Ontario to get their Ontario NT ID numbers, gain access to the BORN Information System (BIS), and receive information on Ontario's NTQA program.

This information also applies to physicians who perform, or who wish to perform NT measurements and submit these to the Ontario MMS labs.

Physicians who report NT measurements acquired by sonographers should ensure that sonographers are complying with the guidance above and the expectations of Ontario's NTQA program.

Physicians who report, but do not scan, NT ultrasounds do not require an Ontario NT ID number. PSO recommends that these physicians complete the Fetal Medicine Foundation (FMF UK) 11-13 weeks scan course to refresh their knowledge on proper NT measurement protocol.
