The Expanded CARN is a new research program that was started in 2013by the ACOG Research Department. This network consists of ACOG Fellows at sites across the United States that participate in practice-based maternal-child health studies using a three-fold approach. Each participating site collects 1) patient survey data; 2) medical provider survey data; and 3) medical record data regarding a specific topic. This approach allows for a research topic to be explored from multiple perspectives. Like all CARN studies, we submit the findings of each Expanded CARN study, in article form, to a peer-review journal for publication. All site principal investigators that contribute to a given study will be co-authors on resulting publications from that study.
In addition to providing a more systematic analysis of clinical use patterns and patient outcomes in the U.S., Expanded CARN seeks to engage ACOG Junior Fellows in the culture of research. When applicable, young investigators will be paired with more experienced researchers at participating sites. While the young investigator will carry-out the primary responsibilities for the study, their mentor and ACOG Research Department staff will provide guidance and assistance on various aspects of the study process from initial IRB submission to the collection and management of data. For all sites, ACOG Research Department staff support Expanded CARN studies by providing necessary study materials, supplies, IRB assistance, data analysis, and the write-up of study results.
We are currently enrolling sites to participate in the following study(s). Please click on the title link(s) below to be taken to that study’s executive summary:
Tracking weight gain, blood pressure, and glucose metabolism during pregnancy
The trajectory of mental health and smoking behaviors during pregnancy
Upcoming studies will focus on: preeclampsia, mental health screening, and breastfeeding intention and success.
