Medical abortion in the United States requires clinic-based follow-up, representing additional time and cost to women and clinics. We studied a semi-quantitative home pregnancy test as a possible replacement for in-person follow-up.
Four hundred and ninety women participated in the clinical study and used a pregnancy test to determine baseline human chorionic gonadotropin (hCG) on the day of mifepristone administration and follow-up hCG 1 week later. One hundred and eighty-nine other women completed a user comprehension survey. Accuracy, feasibility and acceptability of the test were assessed in both the clinical study and the survey.
The test identified the one ongoing pregnancy in the clinical study cohort. Sensitivity and specificity were calculated at 100.0% and 97.0%. The majority of participants in both the clinical study and the user comprehension survey found the test to be "very easy" or "easy" to use.
At-home follow-up with a semi-quantitative pregnancy test is feasible for service delivery in the United States.
在美国，医疗性流产需要在诊所进行后续检查，这给妇女和诊所带来了额外的时间和费用。我们研究了一种半定量家庭妊娠试验，以作为替代面对面随访的可能性。
490 名妇女参加了临床研究，在米非司酮给药当天使用妊娠试验来确定基线人绒毛膜促性腺激素（hCG），并在一周后进行 hCG 随访。另外 189 名妇女完成了用户理解调查。在临床研究和调查中评估了该试验的准确性、可行性和可接受性。
该试验在临床研究队列中识别出了唯一的持续妊娠。灵敏度和特异性分别为 100.0%和 97.0%。临床研究和用户理解调查中的大多数参与者都认为该试验“非常容易”或“容易”使用。
在美国，使用半定量妊娠试验进行家庭随访是可行的服务提供方式。
