We examine quality improvement (QI) collaboratives in 9 states participating in the Children's Health Insurance Program Reauthorization Act (CHIPRA) Quality Demonstration Grant Program. In addition to developing patient-centered medical home (PCMH) capability, some states use collaboratives to familiarize practices with CMS's Initial Core Set of Children's Health Care Quality Measures, practice-level quality measurement, and improving QI knowledge and skills. All states supplement the collaboratives with practice facilitation; the majority utilized practice-level parent engagement, but only 4 used workforce augmentation. Overall, practice staff highly valued aspects of the collaboratives and supplemental strategies but also reported a variety of challenges.
