COPD patients with anxiety have a higher risk of exacerbations

Psychological functioning is an important determinant of health outcomes in chronic lung disease.

COPD was associated with a greater risk of anxiety in multivariable analysis (OR 1.85). Among patients with COPD, anxiety was related to poorer health outcomes including worse submaximal exercise performance (less distance walked during the 6-min walk test) and a greater risk of self-reported functional limitations.

Subjects with COPD with anxiety had a higher risk of COPD exacerbations.

COPD is associated with a higher risk of anxiety. Once anxiety develops among patients with COPD, it is related to poorer health outcomes.

Dr RW: I don't have the full text of this paper, and I wonder if they controlled for continued smoking. Nicotine is a powerful anxiolytic for some COPD patients.

Description

Mayo Clinic Anxiety Coach is a comprehensive self-help tool for reducing a wide variety of fears and worries from extreme shyness to obsessions and compulsions. Anxiety Coach helps you make a list of feared activities and then guides you through mastering them one by one. Through this experience you can increase your confidence as you become less fearful and worried.

Anxiety Coach was developed by two clinical psychologists recognized as experts in the treatment of anxiety disorders. Dr. Stephen P. H. Whiteside is the director of the Pediatric Anxiety Disorders Program at Mayo Clinic. Dr. Jonathan Abramowitz is an internationally known expert on adult anxiety disorders at the University of North Carolina.

The strategies used in Anxiety Coach are based on cognitive behavioral therapy (CBT), the most effective psychotherapy for fears and worries. In CBT people increase their confidence by gradually confronting situations that they have avoided out of fear.
