ABSTRACT
State Perinatal Quality Collaboratives (PQCs) exist in all 50 states, the District of Columbia, and the Armed Forces. All PQCs work to reduce preventable maternal morbidity and mortality through statewide implementation of evidence-based practices. PQCs have been successful in improving outcomes through key strategies, including strong hospital engagement; use of quality-improvement (QI) methodology such as rapid-cycle data review, collaborative learning, and supplemental technical assistance; and strategic partnerships. Here we provide examples of ways four state PQCs have implemented these strategies and their successes. Many PQCs focus on improving in-hospital care with initiatives related to hemorrhage, hypertension, or promoting vaginal birth or other hospital-based care improvements. Given the contribution of mental health, substance use disorder, cardiovascular conditions, and social drivers to postpartum pregnancy-related deaths, PQCs are expanding their scope to include the ambulatory and nonobstetric care settings and more community partners.
