Oct 27, 2017 marks the 50th anniversary of the British Abortion Act, written "to amend and clarify the law relating to termination of pregnancy by registered medical practitioners". 1 Amended in 1990 to include selective reduction of a multiple pregnancy, the Abortion Act governs abortion in England, Scotland, and Wales (Britain), the first law in western Europe to formally legalise abortion for several indications. Abortion is common. Worldwide, an estimated 25% of all pregnancies end in abortion 2 and one in three women in Britain will have an abortion by age 45 years. 3 In 2016, there were more than 200 000 safe abortions in Britain. 3,4 Yet abortion remains controversial-its availability across the world depends less on medical or public health need and more on religious, moral, and political beliefs. Restricting access to abortion does not deter women from seeking one but drives them to unsafe, clandestine procedures from which they may die. In 2011, rates of unsafe abortion were three times higher in countries with more restrictive abortion laws compared with countries with less restrictive laws. 5 Abortion laws are generally more restrictive in lowincome and middle-income countries (LMICs); only 20% of LMICs allow abortion for socioeconomic reasons and 16% on request. 5 Restrictive policies do not reduce abortion rates. In 2010-14, rates were estimated at 34 abortions (90% uncertainty interval 29-46) per 1000 women in countries where abortion is legal on request and 37 (34-51) per 1000 women in countries with no legal grounds for abortion. 2 Liberalising abortion laws saves women's lives. In Romania, the relaxation of abortion legislation in 1989 led to maternal mortality falling by more than 50% in less than 1 year. 6 An analysis by the Guttmacher Institute of countries that have lifted some restrictions to access over the past two decades showed a decline in abortion-related mortality and morbidity. 7 There is no doubt that in those countries with restrictive laws, 50 years of legislation similar to the 1967 Act would have saved millions of lives. Nevertheless, the 1967 Abortion Act in Britain is outdated, placing unjustified and time consuming barriers in the way of women seeking an abortion. Two doctors must give written approval and the procedure must be undertaken in an "approved" place and notified to the Chief Medical Officer. Much has changed in Britain since 1967, when all abortions were undertaken surgically. Abortion today is a simpler and safer procedure: in 2016, 62% of all abortions in England and Wales 3 and 83% in Scotland 4 were medical abortions (mifepristone and misoprostol administered in a health-care setting). The National Health Service (NHS) has also changed. Nurses now do colposcopies, cystoscopies, hysteroscopies, and manage women who have miscarriages, including surgical evacuation of the uterus. Despite their competence, nurses are not allowed to carry out the same procedure for a woman seeking an abortion. Homecare is available for many NHS procedures, including intravenous ch...
