Improving Care TransitionsCare transitions refer to movement of patients from one health care provider or setting to another. For people living with serious and complex illnesses, transitions in setting of care from hospital to home or nursing home, for example are prone to errors. For example, one in five patients discharged from the hospital to home experience an adverse event within three weeks of discharge, when an adverse event is defined as an injury resulting from medical management rather than the underlying disease. The most common adverse events are medication related; they often can be avoided or mitigated. The rate for hospital readmissions among Medicare beneficiaries within 30 days of discharge, one indicator of the appropriateness of the transition process, is 20%, contributing to lower patient satisfaction and rising health care costs.
