Patients ’ Knowledge of Prenatal Screening for Trisomy 21

This study's objective was to assess the knowledge of prenatal screening for Trisomy 21 in pregnant women in one institution in Canada. A cross-sectional survey measuring demographics, knowledge of screening, and health literacy, was administered to pregnant women. Of the 135 women who completed the survey, 74% had adequate knowledge of Trisomy 21 and associated screening procedures. Twenty-eight point one percent of women did not receive any counseling. Overall, 29.5% of women did not know that the screening test was optional and 10.2% of women underwent screening prior to having been counseled. Multigravidity (p< 0.05) and prior counseling (p< 0.001) were positively correlated with knowledge while first language other than English (p< 0.001) was negatively correlated with knowledge. Given these findings, an effort needs to be made on the part of health care providers to increase counseling rates to 100%, stressing the optional nature of the test to attain true informed consent.
