Induced 1st trimester abortion in Denmark 2010 (Updated May, 2011)
Responsible: ějvind Lidegaard
5.1 Medically and surgically
induced 1. trimester abortions in Denmark
1998-2010 (Y1) and the per cent of medical abortions by time (Y2). N = 182,260
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 an almost stable incidence.
The share of medically induced abortions has increased from 2% in 1998 to 56%% in year 2010.
5.2 Induced 1. trimester
abortions in DK 1998-2010 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 57% 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 1998-2010 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
5.4 Medical and surgical induced abortions at Danish Gynaecological departments 2010
Same in per cent
Comments: There are still differences in the proportion of medically
induced abortions at
different departments in Denmark. Herlev, Kolding, and Herning have the highest percentages of medical induction.
At the other side of the spectrum Hvidovre has 24% and Esbjerg 23% medical inductions. 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. Induced abortions in 2010 were only done on special indications
at Rigshospitalet. From 2011 induced abortions from Gentofte have moved to RH.
Note that private hospitals and private practice now conduct 15.3% of all induced 1. trimester abortions.
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
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 = 8,624, n = 374 Absolute number of evacuations indicated at bottom.
Comments: 16 of 18 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 = 105,896, n = 2,219 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.
5.8 Re-evacuations after surgical
induced first trimester abortion in 2010
at different departments. N= 6,712, n = 133
Comments: Small absolute numbers
of re-evacuations at each department. Therefore caution with definitive
conclusions except that all departments have less than 4% re-evacuation rate.
