Health informatics and community health: support for patients as collaborators in care

Health informatics has much to offer community health care. Computer networks and telecommunications provide particular support that can enhance the collaboration among clinicians, care providers and patients. Special-purpose computer tools referred to as Consumer Health Informatics (CHI) represent the application of computer and information technologies specifically to support the health information and communication needs of patients and lay persons. Research projects like ComputerLink and CHESS demonstrate that CHI is acceptable to patients and promotes self-care and disease management. Three grand challenges must be faced to insure realization of the promise of health informatics to community health care: development of knowledge management and information discovery tools for patients, insurance of health information literacy for all persons, and re-engineering clinical practice to capitalize on patients as full partners in health care.
