About

Introduction: Advances in knowledge have contributed to the increase in the number of patients who survive prolonged hospitalization in an Intensive Care Unit (ICU), and, among them, critically ill patients who develop acute respiratory failure and need for mechanical ventilation. These individuals have their mobility restricted to bed, and may suffer from pulmonary and systemic complications, such as ICU-Acquired Muscle Weakness, which increases the chances of resulting in reduced functional capacity or death. Early mobilization in the ICU has demonstrated benefits, but still with a low level of evidence. However, the type and intensity of exercise still need to be better defined, and previous protocols did not offer continuous monitoring from the ICU to the ward and subsequent outpatient rehabilitation for these patients, which is considered a limitation in some studies.

Objective: To investigate the effects of an early and intensive hospital mobilization and post-hospital rehabilitation program on indicators of functionality, inflammation, cost-effectiveness, and mortality in critically ill patients undergoing invasive mechanical ventilation.

Methods: This is a Blind Randomized Controlled Clinical Trial that will be conducted in the ICUs of the Hospital das Clinicas and the Emergency Unit of the Faculty of Medicine of Ribeirao Preto of the University of São Paulo. Patients of both sexes over 21 years of age who have been under invasive mechanical ventilation for at least 24 hours will be recruited. Patients will be randomized into the Intervention Group (IG), with 30 to 60 minutes of exercise per day, and the Control Group (CG), with 10 minutes of exercise per day, both with the same protocol and based on the ICU Mobility Scale - IMS, with continuity in the ward. After hospital discharge, participants will be allocated to the Guidance Group (GIor and GCor) and the Outpatient Rehabilitation Group (GIreab and GCreab), with functional exercise capacity as the main outcome, assessed by the six-minute walk test (6MWT). Volunteers will be monitored one, three, and six months after hospital discharge. The sample calculation was based on the results of the 6MWT , with a power of 80% for the assessments carried out at the proposing institution (n=206), and with a power of 90% for the multicenter project (n=275), considering a sample loss of 30%. The following will be evaluated: clinical parameters, severity indexes, functionality, lung function and mechanics, functional exercise capacity, mortality, inflammatory markers, energy expenditure, activities of daily living, quality of life, muscle assessment, adherence, barriers and facilitators and cost-effectiveness.

Enrollment: 206 estimated patients
