Arizona Connected Care is Southern Arizona's first Accountable Care Organization (ACO), and is a collaboration of independent health care providers in Tucson and Southern Arizona, including more than 150 physicians, three Federally Qualified Health Centers and Tucson Medical Center. Arizona Connected Care is a collaborative, physician-driven organization that works in partnership with a local community-based hospital.

Blue Cross Blue Shield of Arizona (BCBSAZ) started the Patient Centered Medical Home (PCMH) program in 2011 to promote better communication and closer contact between patients and their primary care physicians. The goal of the PCMH program is to improve patient care outcomes by encouraging primary care physicians (PCPs) to practice high quality evidence-based medicine. This program includes five chronic disease conditions, including asthma, congestive heart failure, chronic obstructive pulmonary disorder, diabetes, and hypertension.

Since then, more than 30 additional employers with operations in Arizona have opted to participate in the program, which offers each patient an ongoing relationship with a primary care physician who, in turn, leads a team that takes collective responsibility for each patient's care.
