Patients haunted by fears of living with and dying from severe lung disease
Many patients with chronic progressive pulmonary disease feel anxious and depressed as their conditions advance, as breathing becomes increasingly labored and difficult, and as performing even small daily tasks leaves them exhausted.
Disease-related mental distress can lead to increased disability, more frequent use of costly healthcare resources, higher morbidity, and elevated risk of death, investigators say.
,“Individuals with severe COPD are twice as likely to develop depression than patients with mild COPD. Prevalence rates for clinical anxiety in COPD range from 13% to 46% in outpatients and 10% to 55% among inpatients,” wrote Abebaw Mengitsu Yohannes, PhD, then from Azusa Pacific University in Azusa, California, and colleagues in an article published jointly by The Journal of Family Practice and The Cleveland Clinic Journal of Medicine.
Patients with COPD may experience major depressive disorders, chronic mild depression (dysthymias), and minor depression, as well as generalized anxiety disorder, phobias, and panic disorders, the investigators say.
“Growing evidence suggests that the relationship between mood disorders — particularly depression — and COPD is bidirectional, meaning that mood disorders adversely impact prognosis in COPD, whereas COPD increases the risk of developing depression,” Yohannes et al. wrote.
Jamie Garfield, MD, professor of thoracic medicine and surgery at Temple University’s Lewis Katz School of Medicine in Philadelphia, Pennsylvania, told Chest Physician that the association between severe chronic diseases and mood disorders is well known.
“I don’t think that it’s specific to chronic lung diseases; in people with chronic heart disease or malignancies we see that coexistence of depression and anxiety will worsen the course of disease,” she said.
Dr. Johannes, who is currently a professor of physical therapy at the University of Alabama School of Health Professionals in Birmingham, said that depression and anxiety are often underdiagnosed and undertreated in patients with obstructive pulmonary diseases because the conditions can share symptoms such as dyspnea (for example, in anxiety) or fatigue (in depression).
“Therefore, unless one begins to explore further, it’s hard for physicians to be able to identify these conditions,” he said in an interview with Chest Physician.
Fears of dying (and living)
The causes of depression and anxiety among patients with obstructive pulmonary disorders are multifactorial, and may require a variety of treatment and coping strategies, according to Susann Strang, RN, PhD, and colleagues from the University of Gothenburg, Gothenburg, Sweden.
They conducted qualitative in-depth interviews with 31 men and women with stage III or IV COPD, and found that the majority of patients had anxiety associated with their disease.
“Analyses revealed three major themes: death anxiety, life anxiety, and counterweights to anxiety,” the investigators wrote in a study published in the journal Palliative and Supportive Care in 2014.
Factors contributing to anxiety surrounding death included fear of suffocation, awareness of impending death, fear of the process of death, and anxiety about being separated from loved ones.
In contrast, some patients expressed dread of living with the limitations and loneliness imposed on them by their disease — so-called “life anxiety.”
The patients also reported “counterweights” to anxiety as a way of coping. For some this involved trust in their healthcare professionals and adherence to medication, inhalers, and supplemental oxygen.
“The patients also placed hope in new treatments, better medication, surgery, stem cell treatment, or lung transplants,” Dr. Strang and colleagues reported.
Others reported avoiding talking about death, sleeping more, or using humor to “laugh off this difficult subject.”
