Jill Tucker, RN says:

“All too often, patients are leaving hospitals only to be readmitted within a month’s time—often with health issues exacerbated by their hospital stay. Having a private nurse to accompany the patient when leaving the hospital, to oversee medicine and nutrition intake, to do the heavy lifting, and to tend to the patient’s comfort and recuperation is no longer a luxury, but a necessity. Institutions such as hospitals cannot be relied on for a healthful recovery—patients must now take additional steps to ensure their own well being.”
