“…Besides its relatively simplicity and potential for automation, the main advantages of this method include the early detection of deviations of the measurement compared to other standard quality control indicators. As shown in a recent published study, CUSUM test can be used as a prospective quality control procedure to continuously monitor the performance of sonographers as they assess NT in DS screening [17]. This test model shows close agreement with the retrospective quality review methods on the basis of distribution parameters currently used but with the advantage that it can be prospectively applied, allowing for earlier correction of deviations from target performance.…”

Objective. Quantitative analysis of the quality of nuchal translucency (NT) measurements. Methods. First-trimester combined screening for Down syndrome was performed to all pregnant women attended in our Department from October 2003 to November 2009. NT was measured according to the Fetal Medicine Foundation (FMF) criteria by 20 trained obstetricians. The performance of NT measurements was retrospectively analyzed with regard to several quality control standards. Accuracy according to experience, professional profile, crown rump length (CRL) values, and FMF certification was statistically tested. Results. A total of 14978 NT measurements were assessed. (1) The mean operator-specific median NT-MoM values was 0,98. (2) Mean percentage of cases >95th and <5th centiles were 5,0% and 4,2%, respectively. (3) Logarithmic mean and SD of the NT MoM values were 0,00 and 0,13, respectively. (4) The DR for trisomy 21 at screening time was 90,7% for a FPR of 6,7% for standard screening strategy. (5) According to Cumulative SUM (CUSUM) figures, the performance was more acceptable in FMF-certified operators. Conclusion. Overall, quality standards show optimal NT measurements in our unit. Operator experience, a dedicated profile to fetal medicine, CRL over 60 mm, and FMF certification have a significant positive impact on the quality standards.

“…Mathematical models predict that a drop in the median NT would result in a decrease in detection rate of combined first‐trimester DSS . Observational data also show that some sonographers may underestimate NT . Quality assurance of NT measurements is recommended to ensure that actual measurements fit the expected distribution, on which risk calculation is based .…”

“…It is based on the continuous evaluation of consecutive NT measurements. The advantage of the CUSUM is that it detects early deviations from the expected range and allows immediate corrective intervention, as soon as an unacceptable tendency is noted …”

Objective To assess the quality of nuchal translucency (NT) measurements in primary care and the sonologist's characteristics related with a higher quality. Methods The median NT expressed in multiples of the median (MoM) was calculated for each sonologist of 14 participating antenatal primary care centers of the Catalan Institute of Health. A survey to the sonologists was used to establish variables related to higher‐quality measurements. Results The median NT MoM obtained in 16 448 NT measurements, performed by 102 sonologists, was 0.94 MoM. NT underestimation was observed in 46% of the sonologists. Underestimation were less frequent among professionals who performed more than 230 ultrasounds per year (26% vs 53%;p = .022), those who completed the online Fetal Medicine Foundation (FMF) course (22% vs 54%; p = .021), and those who were subject to periodic audits (24% vs 56%; p = .021). Underestimation rate decreased from 60%, to 33% and 14% with the increase of the years of experience from less than 5 years, to 6 to 15 years and more than 15 years of experience, respectively (p = .029). Conclusions Higher‐quality measurements were demonstrated in sonologists who performed more ultrasounds per year, those with more years of scanning experience, those who completed the online FMF course, and those periodically audited.
