Abstract

Rationale: The evidence base for rehabilitation in pulmonary hypertension is expanding, but adoption in clinical practice is limited. Objectives: The World Health Organization International Classification for Functioning, Disability and Health identifies three health domains: Body Functions/Structures, Activity and Participation in society. To ensure that the wider impact of rehabilitation in pulmonary hypertension is accurately assessed, it is important that study endpoints reflect all three domains. Methods: A systematic review of the literature was conducted to identify studies of rehabilitation in patients with pulmonary hypertension from 2006 to 2019. Results: Searches across five databases yielded 2,564 articles, of which 34 met eligibility criteria; 50 different outcome measures (mean = 5, minimum = 1, maximum = 9) were identified. When mapped onto the World Health Organization International Classification for Functioning, Disability and Health, 48% of instances of outcome usage were measures of Body Functions/Structure, 33% were measures of Activity, and 18% were measures of Participation. Measures of Participation were not included in seven studies (21%). Conclusions: Studies of rehabilitation in pulmonary hypertension have focused primarily on measures of Body Functions/Structure; the impact in other health domains is not well characterized. Greater inclusion of outcome measures reflecting Activity and Participation in society is needed to allow assessment of the wider impact of rehabilitation in patients with pulmonary hypertension.
