Patient Infosystems

Patient Infosystems is a healthcare technology and services company that pioneered automated disease management and population health programs. Founded in 1995, the company developed proprietary software platforms like CareTeamConnect to provide clinical protocols and communication tools for managing chronic conditions such as asthma, diabetes, and heart failure. Its business model focused on reducing healthcare costs for payers and providers by improving patient outcomes through remote monitoring, education, and nurse-led interventions. Following a series of strategic acquisitions and mergers, including American CareSource and Coordinated Care Solutions, the company eventually merged with CareGuide in 2006.
