To evaluate the effects of a home-based pulmonary rehabilitation (PR) programme on hyperventilation symptoms, anxiety and depressive symptoms, general fatigue, health-related quality of life (HRQoL) and exercise capacity in adults with severe asthma who have been exposed to psychosocial chronic stressors.

Data on 111 non-selected consecutive adults with severe asthma who enrolled in an 8-week home-based PR programme (weekly supervised 90-min session) was retrospectively analysed. Chronic stressors included physical, sexual and psychological violence and/or a traumatic experience related to an intensive care unit stay. Hyperventilation symptoms (Nijmegen questionnaire), Hospital Anxiety and Depression Scale, Fatigue Assessment Scale, COPD Assessment Test, Six-Minute Stepper Test and Timed-Up and Go test were assessed at baseline and after PR.

At baseline, participants who have been exposed to chronic stressors (n = 48, 43.2%) were younger, more often female, more often treated for anxiety and depressive disorders, and had a higher score for anxiety symptoms, hyperventilation symptoms and a poorer HRQoL, compared to those who had not been exposed to chronic stressors (p < 0.05). All the study assessments were statistically improved after PR for both groups (p < 0.001). Anxiety and depressive symptoms, fatigue and health-related quality of life questionnaires were also clinically improved based on the minimal clinically important difference.

A large proportion of adults with severe asthma, mainly women, have been exposed to chronic stressors at the time of starting a PR programme, resulting in higher anxiety symptoms and hyperventilation symptoms. However, it did not prevent these individuals from benefiting from PR.
