Three Life Limiting Diseases



The largest percentage of patients seen by our palliative care team in the past six years have been those diagnosed with end stage cancer, but that seems to be changing.  A study published by the National Institutes of Health (NIH) compared patients with advanced cancer, congestive heart failure (CHF), and chronic obstructive pulmonary disease (COPD) to see if there were significant differences in functional capacity, emotional well-being, and quality of life between the three groups after a terminal diagnosis. 

The study concluded that functional status was associated with diagnosis, with CHF and COPD patients faring worse than those with cancer.  Overall, the patient experience was most significantly related to disease severity, demographics, and emotional and social well-being rather than diagnostic category.  This study was interesting to me because CHF and COPD are emerging as significant diagnostic categories for chaplains working in palliative care.

The authors of the NIH study, Karen E. Steinhauser et al., reported, “In the United States cancer, (COPD), and congestive heart failure (CHF) are among the most prevalent life-limiting conditions. Cancer affects 10.7 million Americans, 11.2 million adults have been diagnosed with COPD, and another 4.8 million live with CHF.  Approximately 10% of the adult population lives with serious illness. Each illness produces high rates of hospitalization, disability, and annual mortality.” 

The study confirmed the sense in the field that while our palliative care team tries to build trust early on in the trajectory of the disease, concerns about emotional and social well-being are more significant as the disease becomes more severe.  For this reason, chaplains are typically called in too late in the game when trust has already broken down. Other demographic factors complicate the development of trust.  These include cross-cultural distrust, inadequate financial resources, unavailability of family members to share the emotional burden, homelessness and drug and alcohol abuse.  The presence of these factors sometimes triggers earlier consults for spiritual care. 

Although social, emotional, spiritual, and physical dimensions of quality of life did not differ by diagnostic group, quality of life did vary by disease severity. Social and spiritual well-being varied significantly by gender and ethnicity, with men and non-Caucasians having worse social well-being. Men had almost four times poorer spiritual well-being than women in the study.  Physical well-being was most strongly influenced by disease severity, education, and financial status.  Depression was related to financial status difficulties. Poorer respondents reported higher rates of depression.  My own experience supports these findings, but I had not really considered the significance of those differences.   

The study showed that cancer patients had a similar or better functional status, anxiety, depression, and quality of life compared with patients with CHF and COPD. These results are supported by other recent findings.  A diagnosis of advanced COPD or a CHF diagnosis is viewed less ominously. Advanced cancer's relatively predictable illness pattern shows precipitous functional decline in the last months of life, whereas COPD and CHF trajectories are punctuated with acute exacerbations and periods of rebound in the midst of a graduated overall decline. 

The fact that substantial resources have been assigned to winning the “fight” against cancer, may give a heroic character to the cancer patient while COPD and CHF occur in the aged and are associated with stigmatized lifestyle behaviors such as smoking and obesity.  More research to study the implications of these findings might help us in planning a more effective allocation of palliative care and spiritual care resources.
