Does quality of nuchal translucency measurements correlate with broader aspects of program rigor and culture of excellence? Context: To determine if nuchal translucency (NT) quality correlates with the extent to which clinics vary in rigor and quality control. We correlated NT performance quality (bias and precision) of 246,000 patients with two alternative measures of clinic culture - % of cases for whom nasal bone (NB) measurements were performed and % of requisitions correctly filled for race-ethnicity and weight. When requisition errors occurred in <5% of cases, the average MoM (multiple of the median) was 0.97. When >5% (33%), the curve lowered to 0.93 MoM (p < 0.001) with both bias and precision of measurements impaired. Likewise, for centers with NB >90%, MoM was 0.99 compared to those <10% at 0.93 (p < 0.001). Precision and bias were highly correlated (p < 0.001).

Rigor in NT measurements has improved, but the discussion has been confined to individuals. Progressive educational and remediation strategies need to expand to a second dimension - clinics themselves. Cross-clinic variation in NT quality exists independent of individual variation in NT quality, and two divergent indices of program rigor are associated with NT quality. Quality control must be program wide, and to effect continued improvement in the quality of NT results across time, the cultures of clinics must become a target for intervention. Final Decision: yes
