Outcome measurement for COPD: reliability and validity of the Dyspnea Management Questionnaire

The Effect of Nursing Care Applied to Patients with Chronic Obstructive Pulmonary Disease on Their Sexual Experiences and Quality of Life

This study was conducted for the aim of assessing the effect of nursing care applied to patients with chronic obstructive pulmonary disease on their sexual experiences and quality of life. The sample of the study was determined via power analysis, patients were assigned groups using a simple random sampling method. The data were collected between December 2019-June 2020. The researcher applied the nursing care to patients in the experimental group in their home three times. There was a statistically significant difference between posttest mean scores of the Short Form-36 Health-Related Quality of Life Questionnaire subscales and Arizona Sexual Experiences Scale of the patients in the experimental and control groups (p < 0.05). In this study, it was determined that there was an increase in the Health-Related Quality of Life Questionnaire mean score of patients with COPD after the nursing care; whereas, there was a slight decrease in the Arizona Sexual Experiences Scale mean score.

Psychometric Properties of Patient-Reported Outcome Measures Assessing Self-Efficacy in Patients with Chronic Obstructive Pulmonary Disease (COPD): A Systematic Review

This systematic review aimed to synthesize the evidence of the psychometric properties of self-efficacy patient-reported outcome measures (PROMs) in patients with chronic obstructive pulmonary disease (COPD). We conducted a systematic search of MEDLINE and other common databases from inception until September 2020. Studies that reported psychometric properties of self-efficacy outcome measures in COPD patients were included. We used the Consensus-Based Standards for the Selection of Health Measurement Instruments (COSMIN) 2018 guidelines for data extraction and evidence synthesis. Eighteen studies that assessed nine self-efficacy PROMs were eligible for inclusion. The assessment of structural validity indicated sufficient results rating for the Exercise Self-Regulatory Efficacy Scale and the Self-Care-Self-Efficacy Scale, and insufficient rating for the COPD Self-Efficacy Scale and the Pulmonary Rehabilitation Adaptation Index for Self-Efficacy (PRAISE). Construct validity measures displayed sufficient results rating with correlations ranging from -0.48 to - 0.71 between self-efficacy PROMs and other PROMs such as St. George's Respiratory Questionnaire, Hospital Anxiety and Depression Scale and Chronic Respiratory Questionnaire. Internal consistency measures indicated sufficient rating for all self-efficacy PROMs with a Cronbach's alpha range of 0.71 - 0.98. Responsiveness was assessed for the PRAISE with an overall sufficient rating (effect sizes of 0.21 - 0.37). The evidence regarding the psychometric properties of self-efficacy PROMs in COPD is variable. The PRAISE is responsive to changes in self-efficacy in COPD patients attending a pulmonary rehabilitation program. When using self-efficacy PROMs in clinical practice or research, clinicians and researchers should consider the psychometric properties and choose the appropriate outcome measure based on the purpose.

Self-efficacy and health-related quality of life in chronic obstructive pulmonary disease: A meta-analysis

OBJECTIVE

To determine the association between self-efficacy and health-related quality of life (HRQoL) in people with Chronic Obstructive Pulmonary Disease (COPD) and the moderating effect of self-efficacy type (exercise task, exercise barrier, COPD symptom, general) and HRQoL type (generic, COPD specific).

METHODS

Databases were searched systematically from inception to January 2019. Methodological quality was assessed, and a meta-analysis was conducted following PRISMA guidelines (PROSPERO protocol: CRD42018114846).

RESULTS

Across 31 coefficients, there was a positive relationship between self-efficacy and HRQoL (r = 0.38, 95 %CI [0.32, 0.45]). Exercise barrier self-efficacy had the strongest relationship to HRQoL (r = 0.42, 95 % CI [0.30, 0.52]), followed by COPD symptoms (r = 0.41, 95 % CI [0.33, 0.49]), exercise tasks (r = 0.40, 95 % CI [0.29, 0.50]), and general self-efficacy (r = 0.21, 95 % CI [0.14, 0.28]). Generic HRQoL had a similar relationship to self-efficacy (r = 0.38, 95 % CI [0.28, 0.47]) as COPD specific HRQoL (r = 0.38, 95 % CI [0.30, 0.46]).

CONCLUSION

There is a moderate positive relationship between self-efficacy and HRQoL in COPD, with the relationship stronger for exercise and COPD symptoms than general self-efficacy.

Home nursing care with the self-care model improves self-efficacy of patients with chronic obstructive pulmonary disease

AIM

This study was carried out as an intervention study to determine the effect of nursing care provided at home with the self-care model on the self-efficacy of patients with chronic obstructive pulmonary disease in northern Turkey.

METHODS

The study sample totaled 106 patients with chronic obstructive pulmonary disease divided into two groups. The intervention group and the control group each included 53 patients. To collect data, the patient data sheet, Orem's self-care model-based data collection form, symptom evaluation form, Medical Research Council dyspnea scale, and the chronic obstructive pulmonary disease self-efficacy scale (CSES) were used. The nursing care applied for the intervention group consisted of four visits, two during the first month and two for the next 2 months. An educational guidebook was distributed to the intervention group during the first visit, and at all visits, education, care, and supervision were provided according to the care plan. All data were analyzed with the number, percentage, χ(2) -test, Kruskal-Wallis H test, Wilcoxon rank sum test, and Mann-Whitney U-test.

RESULTS

The dyspnea level measured at the last visit for the control group was high compared with the intervention group (P < 0.05). The chronic obstructive pulmonary disease self-efficacy scale scores for subscale dimensions at the last visit and the general score for the intervention group were high compared with the first visit scores (P < 0.05).

CONCLUSION

According to the study results, home nursing care based on the Orem's self-care model is effective in improving self-efficacy of patients with chronic obstructive pulmonary disease.

A review of the most common patient-reported outcomes in COPD--revisiting current knowledge and estimating future challenges

Patient-reported outcome (PRO) measures that quantify disease impact have become important measures of outcome in COPD research and treatment. The objective of this literature review was to comprehensively evaluate psychometric properties of available PRO instruments and the ability of each of them to characterize pharmaceutical treatment effects from published clinical trial evidence. Identified in this study were several PRO measures, both those that have been used extensively in COPD clinical trials (St George’s Respiratory Questionnaire and Chronic Respiratory Questionnaire) and new instruments whose full value is still to be determined. This suggests a great need for more information about the patient experience of treatment benefit, but this also may pose challenges to researchers, clinicians, and other important stakeholders (eg, regulatory agencies, pharmaceutical companies) who develop new treatment entities and payers (including but not limited to health technology assessment agencies such as the National Institute for Health and Care Excellence and the Canadian Agency for Drugs and Technologies in Health). The purpose of this review is to enable researchers and clinicians to gain a broad overview of PRO measures in COPD by summarizing the value and purpose of these measures and by providing sufficient detail for interested audiences to determine which instrument may be the most suitable for evaluating a particular research purpose.

Evidence for cognitive-behavioral strategies improving dyspnea and related distress in COPD

BACKGROUND

Dyspnea is a complex, prevalent, and distressing symptom of chronic obstructive pulmonary disease (COPD) associated with decreased quality of life, significant disability, and increased mortality. It is a major reason for referral to pulmonary rehabilitation.

METHODS

We reviewed 23 COPD studies to examine the evidence for the effectiveness of cognitive-behavioral strategies for relieving dyspnea in COPD.

RESULTS

Preliminary evidence from randomized controlled trials exists to support cognitive- behavioral strategies, used with or without exercise, for relieving sensory and affective components of dyspnea in COPD. Small to moderate treatment effects for relieving dyspnea were noted for psychotherapy (effect size [ES] = 0.08-0.25 for intensity; 0.26-0.65 for mastery) and distractive auditory stimuli (ES = 0.08-0.33 for intensity; 0.09 to -0.61 for functional burden). Small to large dyspnea improvements resulted from yoga (ES = 0.2-1.21 for intensity; 0.67 for distress; 0.07 for mastery; and -8.37 for functional burden); dyspnea self-management education with exercise (ES = -0.14 to -1.15 for intensity; -0.62 to -0.69 for distress; 1.04 for mastery; 0.14-0.35 for self-efficacy); and slow-breathing exercises (ES = -0.34 to -0.83 for intensity; -0.61 to -0.80 for distress; and 0.62 for self-efficacy). Cognitive-behavioral interventions may relieve dyspnea in COPD by (1) decreasing sympathetic nerve activity, dynamic hyperinflation, and comorbid anxiety, and (2) promoting arterial oxygen saturation, myelinated vagus nerve activity, a greater exercise training effect, and neuroplasticity.

CONCLUSION

While evidence is increasing, additional randomized controlled trials are needed to evaluate the effectiveness of psychosocial and self-management interventions in relieving dyspnea, in order to make them more available to patients and to endorse them in official COPD, dyspnea, and pulmonary rehabilitation practice guidelines. By relieving dyspnea and related anxiety, such interventions may promote adherence to exercise programs and adaptive lifestyle change.

Occupational therapy interventions for people living with advanced lung cancer

SUMMARY Occupational therapists are an integral part of the lung cancer multidisciplinary team, focusing on interventions to assist continued participation in activities that are valued as meaningful for the individual patient. The interventions occupational therapists utilize play a vital role in the management of refractory symptoms for people living with advanced lung cancer. Core interventions, such as energy conservation, anxiety management, home assessments, assistive equipment, technological devices and breathlessness management, are employed by occupational therapists to optimize function and enable participation in chosen, everyday activities, and will be reviewed in this paper.

A multidimensional computer adaptive test approach to dyspnea assessment

OBJECTIVES

To develop and test a prototype dyspnea computer adaptive test (CAT).

DESIGN

Prospective study.

SETTING

Two outpatient medical facilities.

PARTICIPANTS

A convenience sample of adults (N=292) with chronic obstructive pulmonary disease (COPD).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

We developed a modified and expanded item bank and CAT for the Dyspnea Management Questionnaire (DMQ), an outcome measure consisting of 4 dyspnea dimensions: dyspnea intensity, dyspnea anxiety, activity avoidance, and activity self-efficacy.

RESULTS

Factor analyses supported a 4-dimensional model underlying the 71 DMQ items. The DMQ item bank achieved acceptable Rasch model fit statistics, good measurement breadth with minimal floor and ceiling effects, and evidence of high internal consistency reliability (α=.92-.98). With the use of CAT simulation analyses, the DMQ-CAT showed high measurement accuracy compared with the total item pool (r=.83-.97, P<.0001) and evidence of good to excellent concurrent validity (r=-.61 to -.80, P<.0001). All DMQ-CAT domains showed evidence for known-groups validity (P≤.001).

CONCLUSIONS

The DMQ-CAT reliably and validly captured 4 distinct dyspnea domains. Multidimensional dyspnea assessment in COPD is needed to better measure the effectiveness of pharmacologic, pulmonary rehabilitation, and psychosocial interventions in not only alleviating the somatic sensation of dyspnea but also reducing dysfunctional emotions, cognitions, and behaviors associated with dyspnea, especially for anxious patients.
