Chronic conditions such as knee or hip osteoarthritis (OA), chronic obstructive pulmonary disease (COPD), heart failure (HF), coronary heart disease (CHD), hypertension, type 2 diabetes mellitus (T2DM) and depression are among the leading causes of global disability and affect hundreds of millions of people around the world. In recent years, multimorbidity, commonly defined as the co-occurrence of at least two chronic conditions, has also gained interest due to its substantial impact on the person and society. In general, multimorbidity affects more than half of all people with chronic conditions. Two out of three people with OA have comorbidities, with HF, CHD, hypertension, T2DM, COPD and depression being some of the most common. People with multimorbidity account for 78% of all consultations in primary care and multimorbidity is associated with poorer function and quality of life, depression, intake of multiple drugs and increased health care utilization, with some studies demonstrating an almost exponential relationship between the number of chronic conditions and their health care costs. Furthermore, we know from qualitative research that treating one condition at a time is inconvenient, inefficient and unsatisfactory for the person with the chronic conditions and his or her health care provider. Most research so far has excluded people with multimorbidity, due to its focus on only one specific condition, and most of the health care sector manages each individual condition on its own instead of the person, highlighting the negative impact of the current disease-based curative models on multimorbidity. With a population that is ageing, and a significant number of people with multimorbidity being younger than 65 years of age, the proportion of people with multimorbidity is increasing rapidly, emphasizing the need to take action to deal with the increasing burden of chronic conditions and multimorbidity through treatment and prevention. Identifying and developing effective and affordable treatment strategies to deal with the global burden of chronic conditions and multimorbidity is a major focus of modern health care around the world. Despite the significant burden of multimorbidity, little is known about how to treat this effectively. A 2016 Cochrane systematic review found that interventions targeting populations with specific combinations of conditions and addressing specific problems such as functional difficulties may be more effective. A treatment addressing functional limitations that is able to improve symptoms in at least 26 chronic conditions, including OA, HF, CHD, hypertension, T2DM, COPD and depression is readily available. This treatment is exercise therapy, which is effective, safe and supported by substantial evidence in patients with knee and hip OA, HF and CHD, hypertension, T2DM, COPD, depression and a range of other chronic conditions. A new systematic review found that exercise seems effective in people with multimorbidity (the conditions included in the current study), however highlighting the need for further high-quality RCTs. Furthermore, self-management is increasingly recognized as an essential component of interventions to improve outcomes in patients living with multimorbidity. There is increasing evidence that effective management of multimorbidity requires the active participation by patients in the care process. Self-management interventions have been shown to change health behaviors, improve health status, and reduce health care utilization and costs. Self-management support is centered on enabling patients to develop a set of behavioral skills and abilities to help them navigate a range of disease management tasks across different chronic conditions. In an RCT of people with knee OA, published in the New England Journal of Medicine, we found that 3 out of 4 patients eligible for total knee replacement improved enough from self-management, supervised exercise therapy and other non-surgical treatments to postpone surgery for at least one year. Furthermore, in patients with T2DM, 56% did not take antidiabetic medication after 1 year of supervised exercise therapy, self-management and diet. Together, these studies indicate the potential of combining exercise, self-management and other treatments to reduce the need for surgery and medication. A recent cohort study found that an eight-week exercise and self-management program demonstrated similar improvements in health outcomes for people with OA and the comorbidities included in the current study as for people without comorbidities. Altogether, this highlights exercise therapy and self-management as viable treatment options for people with multimorbidity, but the evidence supporting this is of low quality and more high-quality RCTs are needed to improve care for the millions of people suffering from multimorbidity worldwide. The overall aim of the MOBILIZE project is to empower patients with multimorbidity to take a more active role in their health care through a personalized exercise therapy and self-management program so that they may reduce symptoms of the individual conditions, increase quality of life and physical function and prevent development of other chronic conditions. To ensure relevance to the patients and the health care system and to make sure that the project is implementable in clinical practice afterwards, strong interdisciplinary collaboration involving many different scientific methodologies and a high degree of patient involvement throughout the entire research process are at the heart of the project. The MOBILIZE project has received funding from several foundations, including the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation program (grant agreement No 801790). Building on the Medical Research Council's framework for the development and evaluation of complex interventions, the MOBILIZE project has four phases. During the first phase of the project, outcomes and biomarkers that predict better health outcome from different types of exercise therapy and exercise characteristics associated with a better outcome in people with different combinations of chronic conditions will be identified through exploratory observational cohort studies of people with osteoarthritis who have undergone an 8-week exercise therapy and education program in Denmark (GLA:D) as well as scoping reviews, systematic reviews and meta-analyses that summarize the existing evidence. Subsequently, in phase 2, a 12-week exercise therapy and self-management program will be developed based on existing recommendations for exercise and strategies to facilitate behavioral changes. To ensure a high degree of patient and provider involvement, focus group interviews will be conducted with patients with multimorbidity, health care providers and other relevant stakeholders to acquire their views and perspectives on multimorbidity and exercise. Once this phase is completed, the exercise therapy and self-management program will be tested in a feasibility trial involving 20 patients with multimorbidity (recruited from Feb 2021 and onwards). The same procedures and outcomes as in the subsequent RCT will be used, and data will be collected at baseline and immediately after the intervention (12 weeks). The feasibility trial will primarily focus on feasibility outcomes (recruitment, retention, adherence to treatment, burden of outcomes, improvements in outcomes, adverse events), using a red/amber/green traffic light system, guiding the progression to the subsequent RCT. Experiences from the feasibility trial will be used to evaluate and implement any adjustments that need to be made prior to commencing the RCT (described in details in the current trial registration). The RCT corresponds to phase 3, while phase 4 focuses on developing a model for implementation of the personalized exercise therapy and self-management program in clinical practice, if supported by the study findings. The aim of the RCT described in this clinical trial registration is to investigate the effects of a personalized exercise therapy and self-management program in addition to usual care on self-reported, objectively measured and physiological outcomes in people with multimorbidity (i.e. at least two of the following conditions: OA (knee or hip), heart condition (HF or CHD), hypertension, T2DM, COPD and depression). The primary endpoint is 12 months, but 12-week and 6-month follow-ups are included as well and a 12-month health economic evaluation of the program will be conducted. The primary study hypothesis is that a personalized exercise therapy and self-management program in addition to usual care will improve quality of life more than usual care alone when measured at 12 months with concurrent positive effects on secondary outcomes. Furthermore, it is hypothesized that the program will be cost-effective at 12 months. People who only fulfill some of the eligibility criteria (at least 18 years old, at least two of the relevant conditions and do not have an unstable health condition or are at risk of serious adverse events as evaluated by a medical specialist and do not have psychosis disorders, post-traumatic stress disorder, Obsessive Compulsive Disorder, attention deficit hyperactivity disorder, autism, anorexia nervosa/bulimia nervosa or an abuse) and people fulfilling all eligibility criteria, but are unwilling to participate in the RCT, will be offered participation in an observational cohort study where only the self-reported outcomes are completed. Recruitment for the cohort will start and end with the recruitment for the RCT.
