SUPPLEMENTARY INFORMATION:

The Agency for Healthcare Research and Quality has commissioned the Evidence-based Practice Centers (EPC) Program to complete a review of the evidence for Postpartum Home Blood Pressure Monitoring, Postpartum Treatment of Hypertensive Disorders of Pregnancy, and Peripartum Magnesium Sulfate Regimens for Preeclampsia With Severe Features. AHRQ is conducting this systematic review pursuant to Section 902 of the Public Health Service Act, 42 U.S.C. 299a.

The EPC Program is dedicated to identifying as many studies as possible that are relevant to the questions for each of its reviews. In order to do so, we are supplementing the usual manual and electronic database searches of the literature by requesting information from the public ( e.g., details of studies conducted). We are looking for studies that report on Postpartum Home Blood Pressure Monitoring, Postpartum Treatment of Hypertensive Disorders of Pregnancy, and Peripartum Magnesium Sulfate Regimens for Preeclampsia With Severe Features, including those that describe adverse events. The entire research protocol is available online at: https://effectivehealthcare.ahrq.gov/products/hypertensive-disorders-pregnancy/protocol.

This is to notify the public that the EPC Program would find the following information on Postpartum Home Blood Pressure Monitoring, Postpartum Treatment of Hypertensive Disorders of Pregnancy, and Peripartum Magnesium Sulfate Regimens for Preeclampsia With Severe Features helpful:

A list of completed studies that your organization has sponsored for this indication. In the list, please indicate whether results are available on ClinicalTrials.gov along with the ClinicalTrials.gov trial number.

[top] The systematic review will answer the following questions. This information is provided as background. AHRQ is not requesting that the public provide answers to these questions. page 18019

Key Questions (KQ)

KQ 1: What are the effectiveness, comparative effectiveness, and harms of home blood pressure monitoring/telemonitoring in postpartum individuals?

KQ 2: What are the effectiveness, comparative effectiveness, and harms of pharmacological treatments for hypertensive disorders of pregnancy in postpartum individuals?

KQ 3: What are the comparative effectiveness and harms of alternative magnesium sulfate (MgSO 4 ) treatment regimens to treat preeclampsia with severe features during the peripartum period?

3.a. Are there harms associated with the concomitant use of particular antihypertensive medications during treatment with MgSO 4 ?

For all Key Questions, how do the findings vary by race, ethnicity, HDP subgroup, maternal age, parity, singleton/multiple pregnancies, mode of delivery, co-occurring conditions ( e.g., obesity), and social determinants of health ( e.g., postpartum insurance coverage, English proficiency, income, educational attainment)?
