Induced 1st trimester abortion in Denmark 2011 (Updated Aug, 2012)
Responsible: Øjvind Lidegaard
5.1 Medically and surgically induced 1. trimester abortions in Denmark
1998-2011 (Y1) and the per cent of medical abortions by time (Y2). N = 212,242
Same in per
cent
Comments: The total number of induced 1. trimester
abortions decreased until 2006. Thereafter
we have seen a modest increase and from 2008 a slight decrease.
The share of medically induced abortions has increased from 2% in 1998 to 58%
in year 2011.
5.2 Induced 1. trimester
abortions in DK 1998-2011 according to gestational age.
N=182,260. Unknown gestational
age: 152
Same in per cent
Comments: At the same time as the proportion of
medically induced abortions has increased,
women attend our clinics earlier today than before. Now 60%
of all induced abortions
are done before 8 weeks of gestation. In 1998 less than 25% was done
before 8 weeks.
5.3 Annual
induced abortion rate (per 1,000) in DK 1998-2011 in different age groups
Comments: Women below 25 years have had a significant
increase in induced abortion since year
2000. The increase among very young women (<15 years) has ceased so that we
now have levels comparable
with the situation ten years ago. Among women above 30 years, the abortion
rates have been
stable.
5.4 Medical and surgical induced abortions at Danish Gynaecological departments 2011
Same in per cent
Comments: There are still differences in the proportion
of medically induced abortions at
different departments in Denmark. Herlev, Sønderlylland, Kolding, and Herning
have the highest percentages of medical induction.
At the other side of the spectrum Hvidovre has 20%.
It is hardly differences in the populations belonging to the different
hospitals which explain these differences, rather differences in attitudes and
opinions between the professional staffs.
Note that private hospitals and private practice now conduct 19% of all induced
1. trimester abortions.
5.5 Evacuation rate (%) after medically induced first
trimester abortions in
Denmark 2000-2010. Gestational age 4+0 - 8+6. N =57,090, n = 2,739
Figures at
bottom in each column indicate absolute number of evacuations
Comments: The evacuation rate has been rather stable
through the last eleven years.
During this period, the majority of departments changed the medical regimen
from
600mg to 200mg mifepristone. This change has not
changed the efficacy significantly.
5.6. Evacuation rate (%) after medically induced abortions
with GA less
than 9 weeks at
different Gynaecological departments in 2010.
N = 8,475, n = 477
Absolute number of evacuations indicated at bottom.
Comments: 6 of 16
departments fulfill a standard of less than 6%
evacuated after medical abortion.
5.7 Re-evacuation rate (%) after surgical 1. trimester
abortions in DK 2000-2010.
N = 112,067, n = 2,319 Absolute number of re-evacuations
indicated at bottom of columns
Comments:
The re-evacuation rate after surgical abortion is around 2%, which
is less
than half of the risk of evacuation after medically induced first trimester
abortion.
