简要总结
There are data showing that a majority of pregnant women may not be accurately identified as high risk through screening and therefore, not receiving prophylactic low dose aspirin as recommended. This leads to missing many patients who would benefit from aspirin administration. Aspirin is an effective, affordable and safe intervention and its universal use in pregnancy has been proposed as the answer to help mitigate risk of significant morbidity from preeclampsia. However, adherence to aspirin in women at low risk compared to those deemed at high risk of preeclampsia has never been studied. One of the arguments against universal aspirin administration is the concern that universal receipt would change the compliance in those at high risk although there are no data to support this concern. To address the lack of data on differences in adherence, our goal in this proposal is to assess whether there is a difference in adherence to low dose aspirin (81 mg) in women at high risk of preeclampsia as indicated by USPSTF risk algorithm when compared to those women randomized to universal use.
详细描述
Research objective- To compare adherence to low dose, 81mg of aspirin in women considered high risk by USPSTF criteria vs universal receipt.
Hypothesis
Women considered high risk by USPSTF criteria will have better adherence to low dose aspirin than women randomized to universal receipt.
Study Design: Randomized trial
Population: English or Spanish speaking women between 10-20 weeks of gestation receiving their care at Women & Infants Hospital, with a plan to deliver at Women & Infants Hospital
Once enrolled, patients will then be randomized to USPSTF criteria to determine if they qualify for aspirin or to universal aspirin receipt. Once randomized, patients will undergo video pill counts at multiple intervals in their prenatal care (monthly).

研究组 & 干预措施
Randomized to USPSTF Criteria
Women randomized to knowing their risk of preeclampsia and therefore, candidates for low dose aspirin.
干预措施: Low-dose aspirin (Drug)
Randomized to Universal aspirin receipt
Women randomized to receiving low dose aspirin without knowing their risk status.
干预措施: Low-dose aspirin (Drug)
结局指标
主要结局
Adherence to aspirin use
时间窗: up to 42 weeks.
A Research Coordinator will contact each patient within 7 days of recruitment to assure the patient has picked up and has their prescription with subsequent contacts occurring at 30-day intervals until delivery.
次要结局
- Rates of postpartum hemorrhage(These will be assessed within 24 hours after delivery.)
- Rates of preeclampsia(Rates of hypertensive disease of pregnancy will be measured from 20 weeks of gestation until 6 weeks postpartum)
- Fetal growth restriction(This will be measured from 24 weeks until 39 weeks.)
- Placental abruption(This will be measured from 20 weeks until 42 weeks.)
