title: Preventing infective sequelae of abortion.
abstract: Pelvic infection complicates up to 12% of induced abortions and has an adverse effect on future reproductive outcome. The presence in the lower genital tract of Neisseria gonorrhoeae, Chlamydia trachomatis or the anaerobic organisms characterizing bacterial vaginosis is associated with an increased risk of post-abortion infective morbidity. Meta-analysis of randomized trials has shown that prophylaxis with antibiotics effective against either C. trachomatis or bacterial vaginosis reduces the risk of post-abortion infective morbidity by around a half. Other strategies which have been advocated for minimizing the risk of infective morbidity are screening for lower genital tract infections, with treatment of positive cases only, and a combined strategy where women are screened for sexually transmitted infections as well as receiving prophylaxis. These strategies provide the opportunity for appropriate follow-up and partner notification of those women found to have sexually transmitted infections. A multicentre study designed to determine the prevalence of genital tract infections among Scottish women seeking induced abortion, and to compare strategies of 'universal prophylaxis' and 'screen and treat' for minimizing infective morbidity in such women has been undertaken. A total of 1672 women were recruited. Prevalence rates of lower genital tract gonorrhoea, chlamydia and bacterial vaginosis were found to be similar to those reported in other UK studies. Women managed by the 'screen and treat' strategy (particularly those whose genital tract swabs were reported negative) had slightly higher rates of infective morbidity in the 8 weeks after abortion than those managed by 'prophylaxis'. Using currently available screening tests and genitourinary medicine services, 'prophylaxis' appears to be the more cost effective of the two strategies studied.
