Effectiveness Rehabilitation Hematopoietic Transplantation (ovERsHOT)

Working hypothesis

• 1. Patients who receive a Hematopoietic Stem Cell Transplantation (HSCT) who follow a comprehensive rehabilitation program, have fewer post-transplant complications, reduce the number of hospital stay days, and return to their daily lives more quickly.
• 2. The economic costs derived from the incorporation of the rehabilitation program will be lower than the savings caused by the decrease in complications, hospital stay and consumption of health resources.

Goals

Main objectives

• To evaluate the quality of life related to health in the hematological patient who has received a HSCT and on which a new preventive functional rehabilitation intervention (other than physiotherapy) is applied.
• To compare the number and type of respiratory and other complications after HSCT among the intervention group compared to a control group.
• Estimate the effects of the rehabilitation program on tolerance to exercise in the short, medium and long term, as well as detect the change in lifestyle if this occurred.

Secondary objectives

• Evaluate and compare the days of hospital stay and the time elapsed in each of the specialized units (insulation, Intensive Care Unit, single room with High Efficiency Particulate Air, (HEPA filter).
• To qualify the economic costs of the physiotherapy intervention within the rehabilitation program, the complications and the days of hospitalization.
• To evaluate the incidence of muscular atrophy and the level of tolerance to the effort as indicative of physical deconditioning and sedentary lifestyle.
• Measure the amount of symptoms, or the frequency of them: pain (measured by visual analog scale for pain (VAS), nausea / vomiting, insomnia, anxiety, anorexia ...)

Methodology

This is a prospective experimental study with a control group prior to the start of the intervention, which will include 190 participants. The sample size was calculated using a 95% confidence level and considering a positive and negative variability of 50% since there are no previous studies applying this methodology and taking into account the high mortality associated with the infection that oscillates between 35 and 50% according to the studies. The subjects will be treated in the hospital setting in airtight rooms with HEPA filters. Patients will be collected correlatively from the moment they enter the transplant program and sign informed consent. The control group will be collected retrospectively, from the day 1 of the startup of the program to 75, after verifying that they do not meet any inclusion criteria. Recruitment and incorporation into the study will be continuous according to the appearance of cases that meet the inclusion criteria.

The study will include patients receiving HSCT for the next 2 years from the study start date and will be followed and evaluated for a period of one year after transplantation.

Outcomes:

Quality of life, post-transplant complications, especially respiratory, capacity for exercise tolerance, muscular atrophy, onset of sleep disorders, days of stay in different hospital units, cost of interventions: physiotherapy, treatment of complications, and program rehabilitation. Mortality related to the transplantation, which covers any lethal complication from the moment of conditioning and without intervening the patient's underlying disease, that is, the progression of the same. Assess adherence to the program and evaluation and knowledge acquired by the patient.

Measurements:

To make the measurements, use:

• Bioimpedance analysis body composition (BIA), (Quantum X, RJL-Systems instruments™, Mi, USA): This test is performed on the patients in the intervention group at baseline, at discharge from hospital for transplantation, at the month of discharge, and at 3, 6, and 12 months, in order to assess their body composition, their fat mass and their muscle mass.
• Six-minute-walk test (to complement the assessment of exercise tolerance): This test is performed on the patients in the intervention group at baseline, at discharge from hospital for transplantation, at the month of discharge, and at 3, 6, and 12 months, in order to assess the exercise tolerance described in meters traveled, percentage of normality, symptomatology (dyspnea / fatigue of legs), and heart rate recovery. The abrupt weight changes in this population will be decisive for the interpretation of these data.
• Muscle strength test (handgrip (Jamar™ Dynamometer, Preston, Jackson, Mi, USA) and 1RM): This test is performed on the patients in the intervention group at baseline, at discharge from hospital for transplantation, at the month of discharge, and at 3, 6, and 12 months, in order to assess the strength in upper limbs at different times of process.
• Functional Assessment of Cancer Therapy questionnaires (FACT) validated in Spanish, to measure quality of life associated with the disease (lymphoma (LYM), leukemia (LEU), multiple myeloma (MM), Bone marrow transplantation (BMT); fatigue, anorexia): This test is performed on the patients in the intervention group at baseline, at discharge from hospital for transplantation, at the month of discharge, and at 3, 6, and 12 months in order to evaluate subjectively different aspects of health: functional, physical, emotional, as well as other concerns and symptoms associated with the process.
• Physical activity questionnaire for adult subjects -Modified Baecke Questionnaire™- (to measure the sedentary lifestyle): This test is performed on the patients in the intervention group at baseline, at discharge from the transplant hospital, at the month of discharge, and at 3, 6, and 12 months, in order to subjectively assess physical activity which subjects can develop during the first year of the transplant, and if there are limitations due to complications or readmissions.
• Anxiety-depression assessment (HAD) questionnaire. This test is performed on patients in the intervention group at baseline, at discharge from the transplant hospital, at the month of discharge, and at 3, 6, and 12 months, in order to assess the role of anxiety and depression at different times of the transplant and its follow-up in one year.
• Pittsburgh Sleep Quality Index. This test is performed on the patients in the intervention group at baseline, at discharge from the transplant hospital, at the month of discharge, and at 3, 6, and 12 months, in order to assess the subjective quality of sleep in these patients during the transplant period and their follow-up for one year. It is intended to evaluate the previous present difficulties, the use of hypnotics or other drugs used, and the need for continuity of treatments, as well as the effectiveness of them. The quality of sleep in hospitalized patients is highly documented, but it is not present in this type of patients nor is there any longitudinal follow-up.
