Protocol for Prehabilitation Service Implementation in Catalonia

This is a preventive intervention addressed to high risk candidates for major surgical procedures carried out for a period of approximately four weeks before surgery aiming at reducing complications and enhancing post-surgical recovery. It combines: i) high-intensity endurance exercise training and promotion of daily physical activity; ii) nutritional balance; and, iii) psychological support.

The intervention is currently deployed as mainstream service at Hospital Clinic in several types of major surgeries. During fall 2017, three multidisciplinary workshops using a design-thinking approach were carried out to refine the service workflow and to explore the potential for service scalability. The outcomes of the co-design process provided a robust background for the design of a future personalized perioperative care service at regional level covering three phases: prehabilitation, in-patient care, and, post-discharge care.

The current study protocol aims to assess cost-effectiveness of prehabilitation as mainstream service in the ongoing deployment at Hospital Clinic, as well as to generate a roadmap for regional scalability of the service. It is planned as a quasi-experimental case-control study including 500 patients undertaking prehabilitation, as intervention group, and 250 patients following standard conventional care before surgery. The patients will be included from the following type of surgeries (2:1 intervention to control ratio): major digestive surgery (n, 525), lung volume reduction (n, 30), radical cystectomy (n, 30), major cardiovascular surgery (n, 165). Study groups will be made comparable using propensity score matching with the following matching variables: type of surgery, age, sex and adjusted morbidity groups (GMA) scoring.
