Population screening for von Willebrand disease in adolescents with heavy menstrual bleeding.

We used Ohio Medicaid data to determine frequency and predictors of laboratory screening for von Willebrand disease and other bleeding disorders in adolescents with heavy menses. Despite expert guidelines, screening was performed in only a minority of subjects (<15% of those with heavy menses and <25% of those with menstrual bleeding defined as severe), with younger adolescents and those from more urban counties more likely to undergo screening.
