Cohort study of sleep quality in adult patients with acute pulmonary exacerbations of cystic fibrosis.

Background: The impact of an acute pulmonary exacerbation of cystic fibrosis (CF) on sleep quality has not been established. Patients have greater burden of symptoms, higher intensity of therapy and are often admitted to hospital outside of their usual sleeping environment.

Aims: To evaluate the prevalence of, and factors associated with, poor sleep quality in adult patients admitted to hospital with an acute exacerbation of CF lung disease.
