Psycho-Physiological Associates of Dyspnea in Hospitalized Patients with Interstitial Lung Diseases: A Cross-Sectional Study.

ABSTRACT: Dyspnea has been found to be an independent predictor of mortality among patients with respiratory diseases and is often regarded as a difficult symptom to control in patients with interstitial lung diseases (ILDs). Previous studies have found an association of psychological and physiological factors with dyspnea among patients with chronic obstructive airway diseases. However, symptom management of hospitalized patients with ILDs has been hampered by difficulty in priority, since they are often admitted with multiple psycho-physiological needs. This study examined the prevalence of dyspnea and the psycho-physiological factors associated with it among hospitalized Chinese patients with ILDs. We studied 165 hospitalized patients with ILDs recruited consecutively over three months in a public hospital in Guangzhou, China. Dyspnea and common psycho-physiological factors, including cough symptoms, activity capacity, lung function, physical and mental health status, and anxiety and depression symptoms, were measured. By ordered logistic regression, level of dyspnea statistically significantly affected performance in a six-minute walk test and physical functioning in work or other regular daily activities in hospitalized patients with ILDs. Respiratory rehabilitation with an appropriate intensity of exercise training or other strategies for enhancing the physical functioning of this population with moderate and severe levels of dyspnea should be prioritized.

Project description:BackgroundDyspnea is a multidimensional experience similar to pain and is one of the most common clinical presentations in patients with respiratory diseases. Accurately evaluating the experience of dyspnea allows nurses and physicians to deliver better medical services to patients. The multidimensional dyspnea profile emphasizes the psychosocial factors of dyspnea and assesses immediate discomfort, sensory qualities, and the emotional responses of patients with dyspnea. At present, the validity, reliability, and test-retest reliability of the multidimensional dyspnea profile in patients with respiratory diseases in China are unclear.ObjectivesThe aim of this study was to investigate the validity, reliability, and test-retest reliability of the Chinese version of the multidimensional dyspnea profile and to assess the convergent validity between the Chinese version of the multidimensional dyspnea profile and the modified Medical Research Council Dyspnea Scale.MethodsThe factorial construct, intraclass correlations, internal consistency, and convergent validity of the Chinese version of the multidimensional dyspnea profile was evaluated using data from 231 inpatients with dyspnea from the respiratory department of a hospital. In the principal component analysis stage, 131 inpatients were evaluated. In the test-retest reliability analysis stage, 50 out of the 131 patients responded to the questionnaire again. In the confirmatory factor analysis, 100 inpatients from an independent sample were assessed.ResultsThe principal component analysis showed that the Chinese version of the multidimensional dyspnea profile had a two-factor structure: the immediate perceptual-related problem factor (6 items) and the emotional response-related problem factor (5 items). The convergent validity between the Chinese version of the multidimensional dyspnea profile and the modified Medical Research Council Dyspnea Scale was significant and acceptable based on the average variance extracted (r = .56, p < .001). The confirmatory factor analysis revealed a good model fit and provided support for the construct validity of the Chinese version of the multidimensional dyspnea profile. Overall, the internal consistency and intraclass correlation coefficient of the Chinese version of the multidimensional dyspnea profile were good.ConclusionThe 11-item Chinese version of the multidimensional dyspnea profile has acceptable validity and reliability in patients with respiratory diseases in China. In the future, more studies should be performed to further explore its clinical application.
