Accuracy of Menstrual History for Determining Gestational Age Among Adolescents Who Underwent Abortion in England and Wales

Listen to this summary

The authors aimed to evaluate the accuracy of using the last menstrual period (LMP) date for determining gestational age in adolescents under 16 who underwent abortion, comparing it to ultrasonography. They found that while LMP dating had high sensitivity for identifying ineligible patients for no-test medication abortion, it slightly overestimated gestational age. Incorporating additional menstrual history indicators improved sensitivity but reduced specificity, highlighting the need for careful policy considerations regarding access to abortion services for adolescents.
