In the next two decades the aging baby boomers in Germany will gradually be leaving the work force. They are being followed by the much less numerous, "baby bust" generation who now need to finance and staff healthcare for the growing number of old people in society. In order to care for more needy persons with a smaller working population, the healthcare system must be restructured; however, despite these worrisome prospects, the awareness of the problem is still low in many areas. Here we focus on the area in the healthcare system that is growing particularly rapidly and additionally has the greatest need of personnel per patient: the care of the critically ill and functionally impaired patients. The lack of coordination of hospitals, rehabilitation centers and nursing institution is historical in origin. It promotes the tendency to discharge functionally impaired patients to nursing facilities without giving them a chance for recovery of functional autonomy. As the demographic change progresses, this tendency threatens to increase. In afirst of two parts, we attempt to describe the present situation.
