In 2014, our team was awarded a grant from the Patient-Centered Outcomes Research Institute to better understand women’s preferences and expectations in childbirth. In collaboration with our Childbirth Patient-Reported Outcomes (PRO) Partnership, we developed CBEX. CBEX stands for ChildBirth EXperience Survey and is administered online in two parts. Part 1 happens in the third trimester. It asks questions about a woman’s pregnancy history and what kind of services she would like to receive in the hospital for her childbirth. Part 2 happens approximately two months after a woman delivers. It asks about what happened in the hospital during her delivery. Today, we are implementing CBEX in 10 diverse California hospitals.
