The objective was to evaluate whether having intrauterine devices (IUDs), contraceptive implants and injections immediately available to women undergoing abortion, compared to requiring an additional visit for these methods, leads to fewer pregnancies and fewer abortions in the following 12 months.
We conducted a historical cohort study using health records of Medicaid-insured women obtaining a first-trimester surgical abortion within a single practice in New York City. Women in Cohort 1 (2007-2008) needed an additional visit to initiate the IUD or injection. Women in Cohort 2 (2008-2009) were able to initiate these contraceptives and implants during the abortion visit. Women in both cohorts received these methods without additional cost, and all could receive a pill, patch or ring prescription. We compared the proportions of each cohort who experienced a pregnancy that began in the 12 months following the index abortion and also evaluated the outcomes of those pregnancies.
Cohorts 1 and 2 consisted of 407 and 405 women, respectively. The proportions with pregnancy beginning over the following 12 months were substantially greater in Cohort 1 than Cohort 2 (27.3% versus 15.3%, p<.001). Women in Cohort 1 then underwent both more additional abortions (17.2% versus 9.9%, p=.003) and more births (7.9% versus 3.7%, p=.02). The proportion of women in Cohort 1 who initiated IUDs and implants within 12 months was smaller than in Cohort 2 (11% versus 46%, p<.001).
Among women insured by Medicaid, offering immediate comprehensive contraceptive access--including IUDs and implants--on the same day as an induced abortion, compared to requiring an additional visit, increased uptake of IUDs and implants and decreased repeat pregnancies in the next 12 months and abortions.
评估与要求妇女在堕胎后额外就诊以获取宫内节育器(IUD)、避孕植入物和注射剂相比,在堕胎时即刻为妇女提供这些方法是否会导致 12 个月内更少的怀孕和堕胎。
我们采用了一项历史队列研究,使用了在纽约市单一诊所接受早期妊娠手术堕胎的医疗补助保险妇女的健康记录。队列 1 中的妇女(2007-2008 年)需要额外就诊才能开始使用 IUD 或注射剂。队列 2 中的妇女(2008-2009 年)能够在堕胎就诊时开始使用这些避孕方法和植入物。两个队列中的妇女都无需额外付费即可获得这些方法,并且都可以获得药丸、贴片或环的处方。我们比较了两组中在索引堕胎后 12 个月内经历怀孕的比例,并评估了这些怀孕的结局。
队列 1 和 2 分别包括 407 名和 405 名妇女。在接下来的 12 个月内怀孕的比例在队列 1 中明显高于队列 2(27.3%对 15.3%,p<.001)。队列 1 中的妇女随后进行了更多的额外堕胎(17.2%对 9.9%,p=.003)和更多的分娩(7.9%对 3.7%,p=.02)。在 12 个月内开始使用 IUD 和植入物的队列 1 中的妇女比例低于队列 2(11%对 46%,p<.001)。
在医疗补助保险覆盖的妇女中,与要求额外就诊相比,在堕胎当天提供即时综合避孕方法(包括 IUD 和植入物)会增加 IUD 和植入物的使用率,并减少接下来 12 个月内的重复怀孕和堕胎。
