NTQA Requirements
Current NTQA requirements for Ontario |
PSO is currently implementing a Nuchal Translucency Quality Assurance (NTQA) program in Ontario. This will involve changes to how a sonographer maintains their NT certification with the province. PSO will communicate these changes to sonographers via the email address provided in their BORN profiles and will update the list of quality assurance requirements on the PSO website as the program unfolds. Sonographers are required to do the following to maintain their NT certification at this time: How to maintain your NT certification in Ontario

Future NTQA requirements for Ontario |
There are two vital tools used to assess NT measurement performance:
As PSO develops the NTQA program, we are working to support sonographers in their practice by using these tools to assess their NT measurement performance and provide them with actionable feedback to help them improve and/or maintain their skills. We are currently building systems to support these quality assurance requirements; therefore, no action involving these tools is required of sonographers at this time. Please do not send NT/CRL measurement data to PSO at BORN Ontario. We collect all of this data from the first trimester screening requisitions and record it under your personal NT ID number. Please do not send NT images to PSO at BORN Ontario at this time. |
Personalized NT performance distributions |
The Better Outcomes Registry and Network (BORN) Ontario has been collecting prenatal screening information from pregnant individuals' first trimester screening (FTS) requisitions since 2012. BORN has then mapped individualized curves of NT measurements over the 11 to 14 week gestational period for each sonographer according to their NT ID number. Personalized NT performance distributions map each individuals' cumulative NT data against the FMF standardized population curve. You can gain access to your personalized NT performance distribution, housed in the BORN information system (BIS), by registering with PSO at BORN Ontario. Logging in to the BIS to view your personalized performance distributionPlease see these step-by-step instructions for how to log into the BIS to view your personalized NT performance distribution. How to interpret your personalized NT performance distributionPlease see the following resources for more detailed information on how your performance distribution is calculated, how to interpret your distribution, and how it represents your NT scanning practice. |
NT image protocol |
The FMF UK has established protocol for how to obtain high quality NT images. Common mistakes that sonographers make when taking NT images and recording NT measurements on first trimester screening requisitions
Crown rump length (CRL) imagesIt is important to take high quality crown rump length measurements when performing NT ultrasound because the calculation of an individual's risk for chromosomal abnormalities (e.g., Down syndrome and Trisomy 18) for a given pregnancy is based on the NT measurement for the size (CRL) of the fetus.
