This study evaluated care coordination and clinical care management in 46 primary care practices in Massachusetts over 15 months. It found that practices showed statistically significant improvements in documenting follow-up after hospitalization and interactions with care managers. Practices receiving financial assistance had significantly higher rates on two care transition measures and one care management measure. Pediatric practices performed better on care transitions while adult practices performed better on care management. The results demonstrate that practices are learning to implement care coordination and management, though financial support may help with implementation.
