Timing of aspirin initiationIn one meta-analysis, initiating aspirin before 16 weeks’ gestation resulted in a greater reduction in preeclampsia than starting aspirin after 16 weeks.12 The USPSTF cautions that meta-analysis of the available data is not well suited for identifying the optimal time to initiate aspirin therapy.13 ACOG, USPSTF, and NICE recommend initiating aspirin therapy at approximately 12 weeks’ gestation—the end of the first trimester.

Ideal aspirin doseThe optimal dose of aspirin to prevent preeclampsia is not precisely defined. Aspirin doses ranging from 50 mg to 162 mg have been proposed for the prevention of preeclampsia. Most authorities recommend a daily dose between 80 mg and less than 300 mg to prevent preeclampsia.14 ACOG and USPSTF recommend aspirin at a dose of 81 mg daily,6,8 because this dose is widely available in the United States.

Let’s close the gap between current and optimal practiceAccording to the USPSTF guidelines, approximately 24% of the pregnant women in our practices have risk factors that would justify the initiation of aspirin treatment for the prevention of preeclampsia.8 This approach would modestly reduce the rate of preeclampsia and the associated problems of preterm birth and IUGR with little cost and few adverse effects. Yet relatively few pregnant women in the United States are currently receiving aspirin therapy. We could close this clinical gap between current and optimal practice by reflecting on the USPSTF recommendations and implementing them in our practices, as appropriate.
