Abstract
Maternal outcomes in the United States are often negative, despite increasing attention over the last several decades. Improving the quality of care is a key strategy to improve outcomes, and state Perinatal Quality Collaboratives (PQCs) are important networks working to improve maternal health care quality and outcomes. A patient safety bundle is an organized set of evidence-informed practices that are packaged to ease implementation advancing the uptake of these practices and reducing variation in care. PQCs use PSBs and other quality improvement methods to improve hospital care processes, resulting in improved outcomes.
