Research paper: Impact of a new national screening policy for Down syndrome in Denmark: Population based cohort study, BMJ Online
A new national screening strategy in Denmark has halved the number of infants born with Down’s syndrome and increased the number of infants diagnosed before birth by 30%, according to a study published on bmj.com today.
Many countries, including England, Australia and New Zealand, are trying to introduce national screening strategies for Down’s syndrome, but are facing a variety of problems because of a lack of consensus about the screening policy and logistical challenges.
They report that the number of infants born with Down’s syndrome decreased from 55 per year during 2000, to 31 in 2005 and 32 in 2006. The total number of invasive tests fell sharply from 7524 in 2000 to 3510 in 2006.
The detection rate in the screened population was 86% in 2005 and 93% in 2006. With 3.9% (17) of women receiving a false positive result in 2005 and 3.3% (7) in 2006.
I do not know if you like this policy… but I like Denmark’s other policies such as their labor market policy. I think that is less controversial.
