COPD at the end of life: Predictors of the emotional distress of patients and their family caregivers.

Abstract

BackgroundFew studies have focused on patients' emotional distress with end-stage chronic obstructive pulmonary disease (COPD) and their main family caregivers.MethodsCross-sectional data about emotional, functional, and burden-related variables were collected from 85 patients with end-stage COPD and their 85 respective main family caregivers to determine the variables that could predict their emotional well-being. Descriptive analyses, comparison of means, hierarchical regression models, and comparative quali-quantitative analyses were carried out.ResultsData show that the great majority of patients with COPD spend years with this diagnosis, and have been admitted to the hospital several times in advance stage of illness the previous year of the moment of end-of-life stage. Furthermore, only a tiny percentage of the patients were functionally independent in the advanced stage of illness.ConclusionsThe emotional distress and the burden of the family caregiver play an essential role in the distress of the patient, in conjunction with the patient's own functional independence and the time living with the disease, and comorbidity. On the other hand, variables of the patient, such as time since diagnosis, number of hospital admissions, comorbidity, functional dependence, and emotional distress, play an important role in the family caregiver's emotional distress and burden. Understanding how these variables are related is key to designing appropriate programs to reduce the emotional distress the patients with COPD at the end of life and their family caregivers.
