Sleep Disorders in Idiopathic Pulmonary Fibrosis

Wissenschaftliches Institut Bethanien e.V78 enrolled

Overview

This diagnostic observational study was conducted to (1) investigate the prevalence of sleep-related breathing disorders and other sleep disorders in idiopathic pulmonary fibrosis in comparison to COPD, (2) identify characteristics of symptomatic and prognostic significance in idiopathic pulmonary fibrosis with/without sleep disorders, and (3) evaluate different tools for their ability to assess the risk of co-existing sleep disorders in idiopathic pulmonary fibrosis.

Outcomes

Primary Outcomes

Number of patients with any kind of sleep disorder according to the International Classification of Sleep Disorders (ICSD-3)

Sleep disorders defined by the International Classfication of Sleep Disorders are diagnosed by a single sleep study (polysomnography or polygraphy), lasting between 5 and 9 hours for each individual participant. The number of patients for whom at least one sleep disorder is diagnosed, is used to calculate the prevalence of sleep disorders among each patient group.

Time frame: For individual assessment of sleep disorders: one night (between 5 and 9 hours), for overall number of patients: entire study duration (37 months)
