<qa>  What is the goal of the CDC?The available evidence suggests that there are opportunities to optimize the primary care of patients with ACD. We are proposing to build upon the current evidence and guidelines for disease management programs, our existing specialized resources, our existing primary care practices, and develop and test a model of care that is primary care based, sensitive to the unique demands and characteristics of different primary practices. Our goal is to design linkage and care strategies of relevance and importance to the primary care providers who care for patients with advanced COPD and CHF.
