Pre-operative Physical Training for Elderly Patients With Frailty

The average age of hospital patients has steadily increased with the demographic change of Germany's ageing population. In 2014, more than 27 million people living in Germany were older than 60 years and more than one third of this group had to undergo surgery within that year.

A relevant proportion of this patient group has to be considered frail or pre-frail. Over a lifetime every individual experiences a physiological reduction of functional capacity across all organ systems resulting in frailty. Consequently, physical and psychological stress, such as a hospital stay and surgery cannot be readily compensated. Therefore, frailty is a highly predictive pre-operative risk factor for increased post-operative morbidly and mortality, prolonged hospital stay and loss of independence. Multiple studies have demonstrated post-operative outcome of frail patients can be drastically improved if these patients are identified prior to elective surgery and enrolled in a multimodal prehabilitation program. The core of prehabilitation is physical exercise next to nutritional and psychological support. The improvement of cardiovascular condition, ventilator capacity and muscle strength gained during prehabilitation resulted in a reduced incidence of complications including pneumonia, shorter hospital stays and improved quality of life. Yet despite these benefits prehabilitation is not yet widely available outside of clinical studies as they carry considerable costs and demand additional skilled personnel.

In order to provide prehabilitation to a larger group of patients, a pre-operative exercise program was developed, that can safely be followed by pre-frail and frail patients at home without the need of continuous instruction and supervision by a trainer or physiotherapist. Efficacy and feasibility will be evaluated in this study.
