Using a patient-centred composite endpoint in a secondary analysis of the Control of Hypertension in Pregnancy Study (CHIPS) Trial.

Background: Clinical trials commonly use multiple endpoints to measure the impact of an intervention. While this improves the comprehensiveness of outcomes, it can make trial results difficult to interpret. We examined the impact of integrating patient weights into a composite endpoint on the interpretation of Control of Hypertension in Pregnancy Study (CHIPS) Trial results.

Patient Preferences and Decisional Needs When Choosing a Treatment Approach for Pregnancy Hypertension: A Stated Preference Study.

The Hypertension Canada 2018 clinical guidance for pregnancy hypertension recommends antihypertensive therapy for raised blood pressure in pregnancy to a target diastolic blood pressure (BP) of 85 mm Hg (ie, "tight" control). Although evidence shows this approach reduces the incidence of severe maternal hypertension without increasing risk to the baby, we do not know how pregnant women feel about this approach, particularly as they are generally medication averse. An online survey assessed pregnant women's preferences for management of pregnancy hypertension and explored decisional needs.
