Different health professionals — doctors, nurses, therapists, hospice and palliative clinicians, paramedics — working closely with the patient and family on one shared treatment plan, instead of each keeping a separate one. ExpressAgain is where that whole team cares for one patient together. The founder's own definition is on the What is ExpressAgain page and under Questions on How ExpressAgain works.
In the app, the ID in ID Care Plan is short for interdisciplinary: that menu group is the Care Team's shared clinical picture, and every care-team login, whatever its discipline, can read the day's plan there. The Care Team page lists the doctors, nurses, clinics and therapists who help manage the patient's care; the Home Team is the professionals who help the patient at home.
