Clinical features, risk factors, and referral delay in British patients of Indian and European origin with angina matched for age and extent of coronary atheroma.

75-96% of women find medical abortion acceptable, with the corresponding figures for vacuum aspiration ranging from 96% to 100%.20 21 This study suggests that 20% of British women prefer medical abortion and that a further 54% would be willing to use the method. That 26% of women would not contemplate medical abortion shows the importance of providing choice. Travelling distance was the only statistically significant characteristic which identified women with a preference for a method of abortion. Both medical abortion and vacuum aspiration seem to be highly acceptable in women allocated according to preference. However, women without a preference, when allocated at random, found vacuum aspiration significantly more acceptable, especially at longer gestations; even so, medical abortion was acceptable to nearly three quarters ofwomen. This information is useful to clinicians who are required to give practical advice to women applying to have an abortion. Women who prefer a method of abortion should be allowed their choice, regardless of length of gestation. Women presenting very early (less than 50 days' ammenorrhoea) may be reassured that they are likely to find the procedures equally acceptable; medical abortion is at its most effective at shorter gestations.6 Women of 50-63 days' gestation who are not sure which method to use may be advised that vacuum aspiration is likely to be more acceptable. A simple randomised (or entirely pragmatic) trial would not have yielded these results. Hence, the patient centred, partially randomised trial design advocated by Brewin and Bradley may be a useful tool in pragmatic research in populations characterised by an unwillingness to comply with all treatments under investigation.22 Nearly a quarter of the women recruited into this study had had a previous induced abortion. The follow up recommended after medical abortion may provide an excellent opportunity to reinforce counselling about regular and emergency contraception.
