- Brief Summary
As a consequence of the increasing life expectancy hospitals are seeing a growing number of elderly patients undergoing elective surgery. These patients are likely to suffer from one or more chronic illnesses, malnutrition, reduced physical strength and mobility and sensory impairment. Age related loss of resilience in combination with these conditions often results in frailty. Frailty syndrome describes a reduction in weight, mobility and strength, as well as declining cognitive capacities and reduced performance in daily life activities. This decline in constitution is accompanied by an increased risk of complications and mortality in the period after surgery. Frail patients are generally admitted to hospital for a longer period and are readmitted more often.
A multitude of studies has demonstrated that these risks can be significantly reduced by offering frail patients a prevention program prior to their surgery. These prevention programs are often referred to as prehabilitation and combine strength and cardiovascular training with breathing exercises. Despite the obvious benefits, prehabilitation programs are not yet commonly applied outside of research settings as they carry considerable costs and required additional skilled personnel.
In response to the unmet need for a widely applicable, cost and personnel efficient prehabilitation program a home-based prehabilitation program has been designed. This prehabilitation allows patients to safely perform an individualised set of exercises without relying on a personal trainer or a training group. Efficiency and feasibility will be evaluated in this study.
- Detailed Description
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.

Group Intervention Description Prehabilitation Unsupervised home-based physical prehabilitation Participants are scheduled for elective surgery and follow the home-based prehabilitation for 11-17 days Prehabilitation + TAVI Unsupervised home-based physical prehabilitation Study participants who will undergo a TAVI form a subgroup with a modified enrolment procedure and longer duration of the intervention. The prehabilitation period is extended to 30 days.
- Primary Outcome Measures
Name Time Method Quality of recovery: QoR-15 7 days postoperative The quality of recovery after surgery and anaesthesia is measured using the QoR-15 questionnaire. The resulting score indicates self-reported patent well-being and perceived support with higher scores (0-100) indicating a better quality of recovery. (8)
- Secondary Outcome Measures
Name Time Method Quality of recovery: QoR-15 3 months postoperative The quality of recovery after surgery and anaesthesia is measured using the QoR-15 questionnaire. The resulting score indicates self-reported patent well-being and perceived support with higher scores (0-100) indicating a better quality of recovery. (8)
Health related quality of life: Questionnaire Short Form-12 (SF-12) preoperative, 3 months postoperative The World Health Organisation Disability Assessment Schedule (WHODAS) assesses six domains of functioning relating to the quality of life. Quality of life is measured using the Questionnaire Short Form-12 (SF-12), which indicates physical and psychological wellbeing. Higher scores indicate a better health related quality of life.
Duration of hospital admission 3 months postoperative Day of admission to day of discharge
Mobility preoperative, 3 months postoperative The time up\&go-test, in which the subject starts from a sitting position, walks a defined distance of 3 m and returns to a sitting position on a chair is indicative of fall risk and mobility. The chosen cut-off in this study is 10 seconds.
Incidence of postoperative complications preoperative, 7 days and 3 months postoperative Complications reported in hospital files or patient interview
Cognitive performance preoperative, 7 days and 3 months postoperative Cognitive functioning will be tested with the Montreal Cognitive assessment (MOCA), a standardised test that includes memory recall, verbal fluency and visuospatial abilities. A total score between 0 and 30 is calculated with a higher score indicating better cognitive functioning.
Activities of daily living preoperative, 7 days and 3 months postoperative The Lawton-Brody Instrumental Activities of Daily Living is used to assess the ability to perform activities that are central to living independently. A lower score indicates better functioning. The score ranges between 8 - 31
Muscle strength preoperative, 7 days postoperative Grip strength is widely used in the diagnosis of frailty and sarcopenia. It will be measured with a hand held dynamometer in kg, using the dominant hand if possible.
