Abstract
Objective:
In 2009, the California Genetic Disease Branch introduced an aneuploidy screening program allowing Medi-Cal (state insured) patients access to state-sponsored first-trimester screening. The objective of this study was to assess the effect of greater access to prenatal screening on available resources at a single center.
Study Design:
Data of prenatal screening and diagnostic procedures performed 4 months before the introduction of the program were compared with those of 12 months following the introduction.
Result:
Between December 2008 and March 2010, 7689 women underwent first trimester screening, 1286 underwent amniocentesis and 398 underwent chorionic villus sampling. When a comparison was made between the 4 months before and the 12 months after the program's introduction, a greater number of nuchal translucency (NT) examinations was seen to have been performed (384 per month vs 513 per month, P=0.001). Prenatal diagnostic procedures did not increase, but a greater proportion was performed for positive screen results.
Conclusion:
Introduction of the California screening program was associated with increased NT procedures and fewer invasive procedures for advanced maternal age.
