Healthcare integration is a research area that focuses on the coordination and collaboration of different healthcare services and providers in order to improve patient outcomes, reduce costs, and enhance the overall quality and efficiency of healthcare delivery. This may involve integrating various aspects of care, such as primary care, specialty care, mental health services, and social services, as well as integrating information systems and communication channels to ensure seamless transitions and continuity of care for patients. Healthcare integration is seen as a key strategy for addressing the complexity and fragmentation of the healthcare system, and is increasingly being explored as a way to achieve better health outcomes for individuals and populations.
