Surprisingly high prevalence of anxiety and depression in chronic breathing disorders.
OBJECTIVE
The objectives of this study were to assess the prevalence, screening, and recognition of depression and anxiety in persons with chronic breathing disorders, including COPD.


METHODS
Cross-sectional study.


METHODS
The Michael E. DeBakey Veterans Affairs Medical Center (MEDVAMC).


METHODS
A large sample of 1,334 persons with chronic breathing disorder diagnoses who received care at the MEDVAMC.


METHODS
The prevalence of anxiety and depression was measured in a large sample of persons with a chronic breathing disorder diagnosis who received care at the MEDVAMC, using the Primary Care Evaluation of Mental Disorders (PRIME-MD) screening questions. The positive predictive value of the PRIME-MD questions was then determined. The prevalence of anxiety and depressive diagnoses in patients determined to have COPD was then measured, using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID).


RESULTS
Of patients screened with the PRIME-MD, 80% screened positive for depression, anxiety, or both. The predictive value of a positive phone screen for either depression or anxiety was estimated to be 80%. In the subsample of patients who had COPD and received a diagnosis using the SCID, 65% received an anxiety and/or depressive disorder diagnosis. Of those patients, only 31% were receiving treatment for depression and/or anxiety.


CONCLUSIONS
It is troubling that a mere 31% of COPD patients with depression or anxiety are being treated, particularly given their high prevalence in this population. Practical screening instruments may help increase the recognition of anxiety and depression in medical patients, as suggested by the excellent positive predictive value of the PRIME-MD in our study.
