Conventional clinical protocols specify that women initiate depot medroxyprogesterone acetate (DMPA) within 7 days of the onset of menses, and product labeling specifies initiation within 5 days. Women outside of this window should wait until next menses to begin, often leaving them with inadequate interim contraceptive protection. An alternative is for women to initiate monthly hormonal contraception immediately, as a bridge to DMPA, with a scheduled follow-up appointment about 4 weeks later. We evaluated bridge preferences and DMPA initiation among 150 women requesting DMPA who were ineligible for their first injection at the time of clinic visit due to menstrual cycle day. Ninety-eight percent (n = 147) rejected the standard protocol of waiting with condoms or abstinence in favor of a hormonal bridge method. Ninety-seven percent follow-up (n = 146) showed that 86% were satisfied with their bridge method. There were no posttreatment pregnancies, and 55% (n = 81) of participants had initiated DMPA or another long-term contraceptive within 4 weeks of their initial clinic presentation.
传统临床方案规定,女性应在月经开始后的7天内开始使用醋酸甲羟孕酮长效避孕针(DMPA),产品标签则规定在5天内开始使用。处于此时间窗口之外的女性应等到下次月经开始,这往往会使她们在过渡期间得不到足够的避孕保护。另一种选择是,女性立即开始每月使用激素避孕法,作为使用DMPA的过渡,约4周后安排一次随访预约。我们评估了150名因月经周期天数而在就诊时不符合首次注射DMPA条件的女性对过渡方法的偏好以及DMPA的起始情况。98%(n = 147)的女性拒绝了使用避孕套或禁欲等待的标准方案,而选择了激素过渡方法。97%(n = 146)的随访结果显示,86%的女性对其过渡方法感到满意。治疗后没有怀孕情况发生,55%(n = 81)的参与者在首次就诊后的4周内开始使用了DMPA或另一种长效避孕方法。
