COPD Online Rehabilitation (CORe)

Study Overview
=================
Brief Summary
-----------------
International and national publications emphasize that COPD rehabilitation is a key cornerstone in the standard treatment of COPD, based on more than 15 years of research in COPD rehabilitation. COPD rehabilitation improves quality of life, anxiety and depression and physical function. COPD rehabilitation including special physical training, patient-directed education and smoking cessation is core rehabilitation elements, which today are recommended as mandatory content in standard COPD rehabilitation. Standard COPD rehabilitation is an established offer in all regions and municipalities in Denmark. It is however a well-known challenge, that persons with the most severe COPD symptoms and co-morbidities are most likely not to receive COPD rehabilitation. Frequent exacerbations, socially isolation, transport distance to rehabilitation are main reasons why people with severe COPD disease deliberately chooses not to receive COPD rehabilitation. Why there at present are no rehabilitation alternatives for patients with the most severe COPD symptoms, supervised COPD Online rehabilitation in groups, delivered by health professionals in the COPD patients' own home via a computer screen could likely encourage more people to participate. The number of RCT's investigating the effect of supervised Online delivered COPD rehabilitation in groups versus established COPD rehabilitation are very limited. The purpose of this randomized study is to investigate the short-term and long-term efficacy of 10 weeks of online COPD rehabilitation versus conventional supervised COPD rehabilitation in people with severe and very severe COPD. The outcome of the intervention is measured on walking distance, muscle endurance, activity level, quality of life and COPD symptoms respectively. Outcomes are measures before intervention start, end of intervention. This study also collects follow-up update after 3, 6 and 12 month. The follow-up data will be in separate publication. Hypothesis COPD online rehabilitation provides significant larger improvements than the usual care on walking distance, muscle endurance, activity level, and quality of life and COPD symptoms in people with severe and very severe COPD. COPD online rehabilitation and conventional COPD rehabilitation, provides clinically relevant improvement on walking distance, muscle endurance, activity level, quality of life and COPD symptoms in people with severe and very severe COPD.

Interventional Model Description: This study is a randomized controlled, assessor- and statistician blinded, superiority, multicentre trial with two parallel-groups. Online COPD Rehab versus Coventional COPD rehab
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Control group<br>The control group will receive standardized conventional supervised COPD rehabilitation, delivered in groups. Rehabilitation contains exercise training and education sessions twice a week for a duration of 8-12 weeks. | Behavioral: Supervised COPD Rehabilitation (control group)<br>* The control group receives standardized conventional supervised COPD rehabilitation (CCR) in groups. Rehabilitation contains exercise training and education sessions twice a week for a duration of 8-12 weeks. The CCR will last 60-120 minutes each session (50% exercise and 50% education). Physical Exercises in CCR consist endurance based at Borg dyspnea 4-7 for 20-30 minutes and resistance training for upper and lower limb at 50-80% of one repetition maximum of 2-3 sets. Educations sessions consist information a dialogue regarding, life with COPD, participants topics, Medication, daily activity, Nutrition, Smoking cessation, Respiratory and relaxation exercises.<br>|
| Experimental: Online COPD rehabilitation<br>Supervised Online COPD rehabilitation, delivered in groups through a computer screen in patients own home. Rehabilitation contains exercise training and education sessions three times per week for a duration of 10 weeks. | Behavioral: Online COPD rehabilitation (experimental)<br>* Supervised Online COPD rehabilitation, delivered in groups through a computer screen in patients own home. Rehabilitation contains exercise training and education sessions three times per week for a duration of 10 weeks. Each session lasts for 60minutes (60% exercise 40% education). Physical exercises consist high repetitive time-based muscle endurance training, including 5-7 upper and lower limb exercises, performed with a volume of four sets per exercise equivalent to 50-80% of one repetition. Self-rated Borg CR-10 score equivalent from moderate to very strong shortness of breath in active phases. Educations consists same information as for the control group.<br>|
