Ulipristal acetate (UPA) is a prescription emergency contraceptive pill (ECP). Despite the potential for UPA to reduce the risk of unintended pregnancies, a recent study in Hawaii demonstrated less than 3% of pharmacies stocked UPA and less than 23% reported the ability to order it. The primary outcome of our study was to assess the availability of UPA in a sample of large cities nationwide.
We conducted a telephone-based secret shopper study of 533 retail pharmacies sampled proportionally from 10 large cities in five geographic regions across the US. Callers represented themselves as uninsured 18-year-old women attempting to fill prescriptions for UPA between February and May 2016. Using a semi-structured questionnaire, callers inquired regarding availability and use of UPA.
Less than 10% (33/344; 95% CI: 6.5-12.7%) of pharmacies indicated the ability to immediately fill a UPA prescription, while 72% (224/311; 95% CI: 65.0-77.0%) of pharmacies without immediate availability reported the ability to order UPA, with the median predicted wait time of 24 h (IQR: 21.5 to 26.0 h).
Despite evidence for increased efficacy of UPA over levonorgestrel (LNG) ECPs, the availability of UPA in a sample of US major cities is extremely limited. Given that ECPs should be taken as soon as possible after unprotected sex, the long wait times when ordering UPA present an access barrier. Efforts to improve the availability of UPA are important to optimize the potential of ECPs to decrease unintended pregnancy following unprotected sex.
Interventions are needed to address barriers to obtaining UPA from retail pharmacies nationwide.
醋酸乌利司他(UPA)是一种处方紧急避孕药。尽管UPA有降低意外怀孕风险的潜力,但最近在夏威夷进行的一项研究表明,不到3%的药店储备了UPA,不到23%的药店报告有订购能力。我们研究的主要结果是评估UPA在全国大城市样本中的可获得性。
我们对从美国五个地理区域的10个大城市按比例抽取的533家零售药店进行了一项基于电话的暗访研究。打电话者自称是未参保的18岁女性,试图在2016年2月至May月期间开具UPA处方。打电话者使用半结构化问卷询问UPA的可获得性和使用情况。
不到10%(33/344;95%置信区间:6.5 - 12.7%)的药店表示能够立即开具UPA处方,而72%(224/311;95%置信区间:65.0 - 77.0%)没有即时可获得性的药店报告有订购UPA的能力,预计等待时间中位数为24小时(四分位间距:21.5至26.0小时)。
尽管有证据表明UPA比左炔诺孕酮(LNG)紧急避孕药的疗效更高,但在美国主要城市样本中UPA的可获得性极其有限。鉴于紧急避孕药应在无保护性行为后尽快服用,订购UPA时的长时间等待构成了获取障碍。努力提高UPA的可获得性对于优化紧急避孕药在无保护性行为后降低意外怀孕的潜力很重要。
需要采取干预措施来解决在全国零售药店获取UPA的障碍。
