One in four abortions in the UK is undertaken for women who have had one before. Women undergoing abortion in Edinburgh were targeted for improved contraceptive advice and provision in this randomized trial.
Between November 2001 and May 2002, women recruited at assessment for abortion were randomized at admission to receive specialist contraceptive advice and enhanced provision (316 women) or standard care (297 women). Randomization was based on the week of admission. Contraceptive use 16 weeks after abortion was assessed by questionnaire and subsequent abortions by review of the hospital records 2 years later.
Women receiving specialist advice and enhanced provision were more likely to leave the hospital with contraception (271 versus 115, P < 0.001), which was more likely to be a long-acting method (141 versus 78, P < 0.001) than women receiving standard care. Four months later, there was no significant difference in contraceptive prevalence or continuation, but women in the intervention group were more likely to be using contraceptive implants (32 versus 6, P < 0.001). Two years later, 14.6% of women in the intervention group (44/302) and 10% of controls (27/268) had undergone another abortion in the same hospital (P = 0.267).
Specialist contraceptive advice and enhanced provision had a short-lived effect on contraceptive uptake and increased the use of long-acting methods but did not appear to reduce repeat abortions.
在英国,四分之一的堕胎手术是为有过堕胎经历的女性实施的。在这项随机试验中,爱丁堡接受堕胎手术的女性被作为目标对象,以获得更好的避孕建议和避孕措施。
在2001年11月至2002年5月期间,招募来接受堕胎评估的女性在入院时被随机分组,分别接受专业避孕建议和强化避孕措施(316名女性)或标准护理(297名女性)。随机分组基于入院周数。通过问卷调查评估堕胎16周后的避孕措施使用情况,并在2年后通过查阅医院记录评估后续堕胎情况。
接受专业建议和强化避孕措施的女性更有可能在出院时采取避孕措施(271人对115人,P<0.001),与接受标准护理的女性相比,她们更有可能采取长效避孕方法(141人对78人,P<0.001)。四个月后,避孕普及率或避孕措施持续使用情况没有显著差异,但干预组的女性更有可能使用避孕植入物(32人对6人,P<0.001)。两年后,干预组14.6%的女性(44/302)和对照组10%的女性(27/268)在同一家医院再次堕胎(P=0.267)。
专业避孕建议和强化避孕措施对避孕措施的采用有短期影响,并增加了长效避孕方法的使用,但似乎并未减少重复堕胎的情况。
