Pulmonary rehabilitation (PR) is a program that aims to improve the symptoms of people living with chronic lung diseases. As PR services increase in Canada there needs be a way for quality assurance. To address this problem, we are creating quality indicators (QIs). QIs are similar to checklists and will help identify areas in PR that need improvement. This study will use a panel of healthcare professionals and academics in PR to rate which QIs are suitable for quality assurance.
