Prehabilitation, improving postoperative outcomes

Abstract

Cardiopulmonary fitness impacts upon post-operative outcomes. Improved fitness may lead to a reduction in postoperative morbidity, mortality, reduced length of stay and improvements in patients’ quality of life. Prehabilitation can be defined as a group of interventions undertaken prior to a surgical procedure, with the aim of reducing peri-operative risk, improving post-operative recovery and outcomes. This is an evolving field which is generating significant scientific and clinical interest. There is growing evidence demonstrating the effectiveness of this approach. It has been proven that prehabilitation could lead to improvement in cardiopulmonary fitness and reduction of postoperative morbidity. Physical exercise composed of aerobic and strengthening exercise is a mainstay of prehabilitation. Multimodal interventions are preferred nowadays and therefore these programmes are commonly enhanced by nutritional and psychological support. Prehabilitation has its place in elective surgery and should be commenced immediately after diagnosis is made. It can be home-based or within hospitals under supervision. Prehabilitation programmes should be individualised, based on patient’s diagnosis, age, comorbidities, background physical activity and social circumstances in order to achieve the highest possible effectivity of the programmes. It remains unclear as to what the optimal programme looks like in terms of frequency, length and intensity of exercise. High-intensity interval training has been shown to be highly effective. There is a need to answer many questions and bring more substantial evidence of prehabilitation effectivity before this can become part of a routine clinical care. There are...
