Title: A Web-based Self-management Intervention to Increase Level of Physical Activity and Decrease Use of Health Care for People With COPD, in Primary Care: A Protocol for a Randomized Controlled Clinical Trial
Brief Summary: This study evaluates the effects of the COPD Web (KOLwebben), an interactive web-based tool directed towards people with chronic obstructive pulmonary disease (COPD). The COPD Web include tools that improve health literacy with a specific focus on 1) increased physical activity and 2) use of appropriate self-management strategies. This randomized clinical trial aims to generate evidence on the effect and usability of the COPD Web in a properly powered cohort of patients in primary care context.
