Symptom burden in stable COPD patients with moderate or severe airflow limitation

Identification of symptom clusters and change trajectories in patients with acute exacerbation of chronic obstructive pulmonary disease

Aim and objectives

This study aimed to identify symptom cluster (SC) patterns and change trajectories in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), the correlation of the SCs with laboratory and imaging indicators, and the intrinsic association of the SCs with prognostic outcomes and disease burden.

Method

Symptom information was collected using a digital evaluation scoring system at the time of admission, on the third day after admission, and upon discharge. Laboratory and imaging examination data were compiled simultaneously. Exploratory factor analysis was used to identify the AECOPD SCs. The number of factors (clusters) was determined by examining factors with eigenvalues ≥1.0, using 0.50 for factor loadings as the minimum cut-off value. Spearman's correlation analysis was used to explore the link between the SCs and laboratory and imaging indicators, as well as the relationship between the severity of the symptoms in different clusters, prognostic outcomes, and disease burden.

Results

This study included 148 patients. Three SCs were identified: activity-nutrition SC, breath-sleep SC and respiratory SC. Correlation analysis indicated a connection between the activity-nutrition SC and the white blood cell count, and serum sodium and potassium levels, whereas the breath-sleep SC was correlated with white blood cells and eosinophil counts, serum potassium level, and pleural effusion. Additionally, the respiratory SC was associated with serum calcium and magnesium levels, the partial pressure of carbon dioxide, and C-reactive protein (CRP) level. There was a positive correlation between the activity-nutrition SC and hospitalization cost, as well as between the breath-sleep SC and both the hospitalization length and cost.

Conclusion

Patients with AECOPD presented three SCs that affected the length and cost of hospitalization. Concurrently, the severity of the symptoms in the clusters was related to white blood cell and eosinophil counts; serum sodium, potassium, calcium, and magnesium levels; CRP level; the partial pressure of carbon dioxide; and pleural effusion, indicating that the symptoms in each clusters may share related physiological mechanisms. An in-depth exploration of the pathogenesis and intervention paths of health problems is of great significance for promoting precision nursing.

Symptom Burden of Patients with Chronic Obstructive Pulmonary Disease Attending the Westmead Breathlessness Service: Prevalence, Associations, and Sex-Related Differences

Purpose

Chronic obstructive pulmonary disease (COPD) is a progressive disease resulting in a range of symptoms including breathlessness. "Symptom burden" describes the severity and impact of multiple symptoms in an individual and is best quantified using validated symptom instruments but is not routinely measured in clinical practice. Therefore, we wanted to assess overall symptom burden in patients with moderate-to-severe COPD and find associated independent predictors.

Patients and methods

A single-centre cross-sectional study of patients with COPD who attended the Westmead Breathlessness Service between March 2017 and May 2022 was conducted. We obtained baseline demographic data, lung function, assessed quality of life (CAT), anxiety/depression (HADS), and measured symptom burden (CMSAS). We compared variables between men and women using unpaired t tests or Mann-Whitney tests for continuous variables, and Fisher's exact tests for categorical variables. We used multiple regression to look for independent predictors of overall symptom burden. Data were analysed using Stata/IC 15.1.

Results

Eighty-nine patients with COPD, mean age 72.6 years, 55% male, mean FEV1 32% predicted, reported an average of 8.9 symptoms including 6.9 physical and 1.6 psychological symptoms. The most common physical symptoms were shortness of breath (100%) and lack of energy (80%), and the most common psychological symptoms were worrying (65%) and feeling anxious (61%). Median CMSAS total score was higher in women than men (1.34 versus 1.04, respectively; p=0.03) with more women experiencing nervousness (p=0.011) and anxiety (p=0.005). Female sex (p=0.003), HADS-Anxiety (p=0.0001), and HADS-Depression (p=0.0001) were independently associated with total CMSAS score in a multiple linear regression model and explained 63% of total CMSAS variability.

Conclusion

Very high physical and psychological symptom burden exists among patients with severe COPD. Anxiety, depression, and female sex were independently associated with increasing symptom burden. Identifying and understanding sex differences for COPD symptoms, and interventions targeting anxiety and depression may help to reduce overall symptom burden within this population.

Symptom prevalence, severity, distress and management among patients with chronic diseases

BACKGROUND

Advanced knowledge, technology, and treatment approaches resulted in longer survival rates for patients suffering from chronic diseases. However, symptoms of these diseases persist and affect the individual's entire life and normal functioning.

AIM

To assess symptoms prevalence, severity, distress, and management among patients with chronic obstructive pulmonary diseases (COPD), chronic heart failure (CHF), and end-stage renal disease (ESRD) in Oman.

DESIGN

A descriptive cross-sectional design was used.

SAMPLE AND SETTINGS

The study sample comprised 340 participants who were recruited between May and December 2021 from two referral hospitals and one large dialysis unit in the Sultanate of Oman, Muscat Governate using a convenience sampling technique.

RESULTS

The highly prevalent symptoms among patients with selected chronic diseases were lack of energy (60.9%), pain (57.4%), numbness (53.2%), difficulty sleeping (49.4%), and shortness of breath (45.9%). The most severe symptoms were shortness of breath (53.2%), problems with urination (51.9%), constipation (50.8%), difficulty sleeping (49.7%), and pain (46.2%). The symptom "problems with sexual interests or activity" was found to be the most frequently occurring and highly distressing symptom out of all reported symptoms.

CONCLUSIONS

The current study's findings showed that symptoms were prevalent and that some symptoms were frequent, severe, and highly distressing. In addition, patients perceived symptom treatment as inadequate. Psychological symptoms received less treatment attention compared with physical symptoms. One of the mainstays for managing symptoms can be the introduction of palliative care. Providing palliative care to these patients can alleviate their suffering and improve their quality of life. In addition, designing chronic disease self-management programmes can make a difference in patients' life.

Mismatch identified in symptom burden profiles in lung transplantation

BACKGROUND

There is considerable heterogeneity in symptom burden among lung transplant candidates that may not be explained by objective measures of illness severity.

OBJECTIVES

This study aimed to characterize symptom burden, identify distinct profiles based on symptom burden and illness severity, and determine whether observed profiles are defined by differences in social determinates of health (SDOH).

METHODS

This was a prospective study of adult lung transplant candidates. Symptoms were assessed within 3 months of transplant with the Memorial Symptom Assessment Scale (MSAS). MSAS subscale (physical and psychological) scores range 0-4 (higher=more symptom burden). The lung allocation score (LAS) (range 0-100) was our proxy measure of illness severity. The MSAS subscales and LAS were used as continuous indicators in a latent profile analysis to identify distinct symptom-illness severity profiles. Comparative statistics were used to identify SDOH differences among observed profiles.

RESULTS

Among 93 candidates, 3 distinct symptom-illness severity profiles were identified: 71% had a mild profile in which mild symptoms (MSAS physical 0.49; MSAS psychological 0.57) paired with mild illness severity (LAS 38.59). Of the 29% mismatched participants, 9% had moderate symptoms (MSAS physical 0.88; MSAS psychological 1.47) but severe illness severity (LAS 88.02) and 20% had severe symptoms (MSAS physical 1.30; MSAS psychological 1.94) but mild illness severity (LAS 42.13). The two mismatch profiles were younger, more racially diverse, and had higher psychosocial risk scores.

CONCLUSION

Symptom burden is heterogenous, does not always reflect objective measures of illness severity, and may be linked to SDOH.

Symptom clusters, associated factors and health-related quality of life in patients with chronic obstructive pulmonary disease: A structural equation modelling analysis

AIMS AND OBJECTIVES

To identify symptom clusters and develop a symptom cluster model among people living with chronic obstructive pulmonary disease (COPD).

BACKGROUND

The examination of symptom clusters in COPD patients is an emerging field of scientific inquiry directed towards symptom management. However, no studies have modelled the relationships among symptom clusters, associated factors and health-related quality of life.

DESIGN

A cross-sectional design with convenience sampling following STROBE guidelines.

METHODS

Data were collected from 450 COPD participants in three university teaching hospitals. Participants were invited to complete a structured questionnaire comprised of a socio-demographic/clinical questionnaire, Integrated Palliative Care Outcome Scale and Clinical Respiratory Questionnaire. Exploratory factor analysis and confirmatory factor analysis were used to identify symptom clusters. Structural equation modelling was used to examine the proposed model.

RESULTS

The respiratory related symptom cluster, psychological symptom cluster and cough-insomnia related symptom cluster were identified. The final model demonstrated a good fit with the data. Gender, stage of disease and monthly income were significant factors associated with symptom clusters. Respiratory related and cough-insomnia related symptom clusters had a direct negative impact on health-related quality of life, while the psychological symptom cluster was found to have a direct and indirect negative effect on health-related quality of life.

CONCLUSIONS

Final COPD symptom cluster model should serve as a framework to guide intervention research targeting symptom clusters to improve health-related quality of life of people living with COPD.

RELEVANCE TO CLINICAL PRACTICE

Nurses should be especially attuned to identify those at most risk of facing a higher symptom burden in this case those who are female, have advanced stage COPD and/or lower income. During the clinical symptom assessment, nurses should pay attention to the close relationships among symptoms within a cluster to identify any 'trigger' symptom that could cause the development or exacerbation of other symptoms.

Stability of distinct symptom experiences in patients with chronic obstructive pulmonary disease (COPD)

PURPOSE

This study aimed to examine reclassification rates among classes of chronic obstructive pulmonary disease (COPD) patients based on their distinct symptom experiences and to assess how these subgroups differed in symptom scores and health-related quality of life (HRQoL) outcomes over one year. Moreover, we wished to assess how these subgroups differed in demographic and clinical characteristics at 12 months.

PATIENTS AND METHODS

This is a follow-up study of 267 patients with moderate, severe, and very severe COPD. Based on their distinct symptom experiences using the Memorial Symptom Assessment Scale (MSAS), three subgroups (i.e., "high", "intermediate", and "low") were identified at baseline. In the present study, transitions between the subgroups at three, six, nine, and 12 months were investigated and calculated as reclassification rates. Differences among the subgroups in symptom scores and HRQoL at each time point and demographic and clinical characteristics at 12 months were evaluated using analysis of variance with post hoc comparisons.

RESULTS

Almost 65% were still in the "high" class after 12 months. At 12 months, pairwise comparisons for respiratory function measurements were not significantly different. Compared to the "intermediate" and "low" class, patients in the "high" class were more likely to be women and had significantly more comorbidities, reported a significantly higher number of symptoms at all time points, and worse HRQoL scores.

CONCLUSION

Our findings suggest that the pattern of a high symptom burden in COPD is consistent over time. The patients' individual symptom experiences should be the primary focus of treatment.

Symptom burden and functional performance in patients with chronic obstructive pulmonary disease

BACKGROUND

The burden of COPD is growing, and it is one of the leading disease burdens worldwide. Studies on symptom burden as a multidimensional concept in COPD and functional performance are lacking, and little is known about the effect of multiple symptoms and symptom burden on functional performance.

METHODS

A descriptive, cross-sectional correlational survey design was used. The Memorial Symptom Assessment Scale (MSAS) and the Functional Performance Inventory-Short Form (FPI-SF) were used to measure the symptom burden and functional performance. Data were analyzed using descriptive and inferential statistics. Participants (n = 214) were recruited from the respiratory outpatient clinic in one of the teaching hospitals in Ireland.

RESULTS

Patients with COPD, regardless of classification, experienced significant physical and psychological symptom burden. A total of 20 symptoms were negatively correlated with overall functional performance, indicating a high symptom burden for those symptoms was associated with low overall functional performance. A statistically significant negative correlation between physical symptom burden, psychological symptom burden, total symptom burden, and functional performance was found.

CONCLUSION

Patients with COPD experience a significant symptom burden and low functional performance. Decreased functional performance was not related only to a single burdensome symptom, but may also be related to the contribution of several physical/psychological burdensome symptoms, or both. Assessment and management of these symptoms are essential and imply that alleviating these symptoms' burden may promote improved functional performance. This study supported the growing body of evidence of the need for patients with advanced COPD to receive palliative care.

Effect of therapeutic touch on sleep quality and anxiety in individuals with chronic obstructive pulmonary disease: A randomized controlled trial

PURPOSE

The purpose is to determine the effect of therapeutic touch (TT) on the sleep quality and anxiety of individuals with chronic obstructive pulmonary (COPD) disease.

METHODS

103 patients were randomized in to the two groups: the experimental group, and the control group. In this randomized control study, the patients with COPD in the experimental group were given TT for 10 min between 18:00 and 20:00, one session every day for three consecutive days.

RESULTS

When the experimental group was compared to control group following the intervention, the decrease in the levels of anxiety (p < 0.001) and increase in the sleep quality (p < 0.001) were found to be significant.

CONCLUSION

As a result of the study, it was determined that TT reduced anxiety level and improved sleep quality in individuals with chronic obstructive pulmonary disease. The Clinical Trial Registration Number: NCT04842903.

The information needs of people with COPD-The holistic approach with special reference to gender and time since diagnosis

AIMS

The aim of this study was to determine what kinds of unmet information needs people with COPD have and whether there are differences in information needs between genders or based on the time since COPD diagnosis.

DESIGN

A descriptive cross-sectional study.

METHODS

Data on people with COPD (N = 169) were collected from a two-part questionnaire distributed via website. On the first part, information needs concerning the medical aspects of self-management were measured by the Lung Information Needs Questionnaire (LINQ). On the second part, which was developed specifically for this study, a more holistic view of self-management counselling was sought. Statistical methods were used to analyse the data.

RESULTS

The respondents had wide-ranging information needs in many areas of COPD self-management. The most often reported areas of unmet information needs included exacerbations, diet, fatigue, stress and anxiety, palliative care and sexual life. The information needs varied by gender and time since COPD diagnosis.

Chronic Obstructive Pulmonary Disease Symptom Cluster Composition, Associated Factors, and Methodologies: A Systematic Review

This systematic review details symptom clusters, their compositions, and associated factors and appraises the methodologies of studies that reported symptom clusters in patients with chronic obstructive pulmonary disease (COPD). Ten studies were eligible for inclusion in this study. Four common symptom clusters were identified. Two theoretical frameworks, four statistical methods, and various symptom assessment tools were used to identify symptom clusters. Factors associated with symptom clusters included demographic, clinical, and biological factors. No studies examined the subjective experiences of symptom clusters. Overall, inconsistencies were identified in the composition of symptom clusters across studies. This may be due to variations in study design, assessment tools, and statistical methods. Future studies should attempt to arrive at a common definition, especially that is theoretically derived, for symptom clusters, standardize the criteria for symptoms for inclusion in the clusters, and focus on patients' subjective experience to inform which clusters are clinically relevant.

Symptom burden in patients with chronic obstructive pulmonary disease

BACKGROUND

There is now a growing body of evidence to suggest that patients with chronic disease experience their symptoms as a burden. Although symptoms are a principal focus for diagnosis and treatment of chronic obstructive pulmonary disease (COPD), there has been little research to date on symptom burden with reference to frequency, severity, and distress of symptoms.

METHODS

A descriptive, cross-sectional survey design was used. Symptom burden was measured using the Memorial Symptom Assessment Scale (MSAS). A sample of 214 patients with COPD, recruited from one of the major teaching hospitals in Ireland.

RESULTS

Patients experienced a median of 13 symptoms. Patients with 'very severe' COPD experienced the greatest number, with a median of 15 symptoms, followed by those with 'severe' COPD, with a median of 14 symptoms. Patients with 'mild' and 'moderate' COPD reported a median of 10 symptoms each. The most burdensome symptoms were shortness of breath, lack of energy, difficulty sleeping, worrying, dry mouth, feeling nervous, and feeling irritable. Total symptom burden was found to be low. Patients with 'very severe' COPD had the greatest symptom burden, followed by those with 'severe', 'moderate', and 'mild' COPD. Symptom burden was higher for psychological symptoms, with a mean score of 1.60 compared to the physical symptoms (mean = 0.87).

CONCLUSION

Patients with COPD experience a remarkably high number of symptoms, and significant symptom burden of both physical and psychological symptoms. There is a need for early assessment and management of both physical and psychological symptoms in all patients with COPD.

Family members' experiences and expectations of self-management counseling while caring for a person with chronic obstructive pulmonary disease: a systematic review of qualitative evidence

OBJECTIVE

The objective of this review was to identify and synthesize existing evidence on the experiences and expectations of self-management counseling of adult family members who are informal caregivers of a person with chronic obstructive pulmonary disease (COPD) in the context of inpatient or outpatient care.

INTRODUCTION

Chronic obstructive pulmonary disease is the fourth leading cause of mortality and morbidity worldwide. It is a progressive, lifelong and unpredictable disease. As the disease progresses, both the people with COPD and their family members require information and practical skills to manage the disease. The role of family members is particularly important at the advanced stage of COPD. This systematic review examined family members' experiences and expectations of self-management counseling.

INCLUSION CRITERIA

This review considered qualitative studies that investigated adult (older than18 years) family members' experiences or expectations of COPD self-management counseling in the context of inpatient or outpatient care. "Family member" refers to a person who is an informal caregiver because of his or her relationship to the person with COPD.

METHODS

A three-step search strategy was utilized in this review. The search strategy aimed to find published and unpublished studies in English and Finnish. The databases MEDLINE, CINAHL, PsycINFO, Scopus and the Finnish medical bibliographic database, Medic, were searched. The search was conducted in December 2015 and updated in September 2018. Titles and abstracts were screened by two independent reviewers for the review's inclusion criteria. Eligible studies were then critically appraised by two independent reviewers for methodological quality. The findings and illustrations of the findings were extracted and assigned a level of credibility. The qualitative research findings were pooled using the JBI method of meta-aggregation.

RESULTS

Ten papers were selected for inclusion in this review. These studies were published from 2002 to 2017. The quality of all included studies was at least moderate. Each study had a total score between 7 and 10 on the JBI Critical Appraisal Checklist for Qualitative Research. The following four synthesized findings were aggregated from nine categories and 39 study findings: i) Family members' experiences with unresponsive behavior from health professionals, ii) Family members' experiences of unmet needs in self-management counseling, iii) Family members' information needs concerning COPD management, and iv) Family members' information needs concerning coping strategies.

CONCLUSIONS

The synthesized findings indicate that family members are frustrated by the shortcomings of self-management counseling. They also feel unprepared for and uncertain about their caring role. They need more information about COPD and coping strategies for COPD. Counseling is essential to high-quality care and should be offered to family members caring for a loved one at any stage of COPD.

Identification of Symptom Clusters and Their Influencing Factors in Subgroups of Chinese Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease

CONTEXT

Limited studies have identified symptom clusters (SCs) and their risk factors and the relationships with inflammatory biomarkers in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

OBJECTIVES

In this study, we aimed to investigate SCs in patients with AECOPD and explore their influencing factors and relationships with inflammatory biomarkers.

METHODS

Data were collected with sociodemographic and disease information questionnaires, and symptoms were measured with the revised Memorial Symptom Assessment Scale. SCs were extracted through exploratory factor analysis. Logistic regression analysis was conducted to explore the risk factors of SCs.

RESULTS

A total of 151 patients were recruited. Two SCs, namely, emotional and respiratory functional SCs, were identified. Logistic regression analysis showed that individuals with high C-reactive protein level, Charlson Comorbidity Index score, and high modified Medical Research Council Dyspnea Scale score were more likely to belong to the high-severity symptom subgroup than to the low-severity symptom group in the emotional SC. The patients with a low body mass index and without or lax inhaled drug therapy exhibited highly prominent predictors of membership in the high-severity symptom group of the respiratory functional SC.

CONCLUSION

Symptoms experienced by patients with AECOPD were grouped into specific clusters. Targeted interventions should be performed based on SCs, and influencing factors and biological mechanisms should be considered when providing individualized approaches and interventions.

Changes in and predictors of pain and mortality in patients with chronic obstructive pulmonary disease

This longitudinal study of patients with chronic obstructive pulmonary disease (COPD) aimed to investigate changes in pain characteristics (i.e., occurrence, intensity, and interference) and covariates associated with pain from study enrollment to 12 months, and to investigate if the different pain characteristics were associated with 5-year mortality. In total, 267 patients with COPD completed questionnaires five times over 1 year. The mean age of the patients was 63 years (standard deviation: 9.0), 53% were women, and 46% had very severe COPD. Median number of comorbidities was 2.0 (range: 0-11) and 47% of patients reported back/neck pain. Mixed models and Cox regression models were used for analyses. In total, 60% of the patients reported pain at baseline, and 61% at 12 months. The mixed model analyses revealed that those with better forced expiratory volume in 1 s (% predicted), more comorbidities, only primary school education, and more respiratory symptoms reported significantly higher average pain intensity. Moreover, those with more comorbidities, more respiratory symptoms, and more depression reported higher pain interference with function. At the 5-year follow-up, 64 patients (24%) were deceased, and the cumulative 5-year mortality rate was 22% (95% confidence interval [19-25]). Older age, lower forced expiratory volume in 1 s (% predicted), and higher pain interference at enrollment were all independently and significantly associated with higher 5-year mortality. Our findings show that many patients with COPD have persistent pain, and awareness regarding comorbidities and how pain interferes with their lives is needed.

Chronic Obstructive Pulmonary Disease: A Palliative Medicine Review of the Disease, Its Therapies, and Drug Interactions

Despite significant advances in treatment, chronic obstructive pulmonary disease (COPD) remains a chronic and progressive disease that frequently leads to premature mortality. COPD is associated with a constellation of significant symptoms, including dyspnea, cough, wheezing, pain, fatigue, anxiety, depression, and insomnia, and is associated with increased morbidity. Palliative care is appropriate to support these patients. However, historically, palliative care has focused on supporting patients with malignant disease, rather than progressive chronic diseases such as COPD. Therapies for COPD often result in functional and symptomatic improvements, including health-related quality of life (HRQL), and palliative care may further improve symptoms and HRQL. Provision of usual palliative care therapies for this patient population requires understanding the pathogenesis of COPD and common disease-targeted pharmacotherapies, as well as an approach to balancing life-prolonging and HRQL care strategies. This review describes COPD and current targeted therapies and their effects on symptoms, exercise tolerance, HRQL, and survival. It is important to note that medications commonly used for symptom management in palliative care can interact with COPD medications resulting in increased risk of adverse effects, enhanced toxicity, or changes in clearance of medications. To address this, we review pharmacologic interactions with and precautions related to use of COPD therapies in conjunction with commonly used palliative care medications.

Psychosocial issues need more attention in COPD self-management education

Objective: To find out how regularly the contents of patient education regarded as essential for COPD patients' self-management are provided by healthcare professionals in specialised healthcare (SHC) and primary healthcare (PHC) in Finland.Design: A cross-sectional study based on an e-questionnaire with 42 items on the content of self-management education of COPD patients.Setting: The study sample included all public SHC units with pulmonary outpatient clinics (n = 29) and nine out of 160 health centres in Finland.Subjects: 83 doctors and 162 nurses.Main outcome measures: The respondents' answers on how regularly they included the contents regarded as essential for COPD patients' self-management in their education of COPD patients.Results: COPD patients were educated regularly on medical issues regarding COPD treatment, such as smoking cessation, exercise and pharmacological treatment. However, issues vital for coping with the disease, such as psychological well-being, stress management or fatigue, were often ignored. Patient education in SHC seemed to be more systematic than education in PHC. The education provided by the asthma/COPD nurses (n = 70) was more systematic than the education provided by the other nurses (n = 84).Conclusion: Healthcare professionals' continuous education should cover not only the medical but also the psychosocial aspects of coping with COPD. The role of doctors and nurses should be considered to ensure that there is no gap in COPD patients' education. Training asthma/COPD nurses and promoting specialised nurse-led asthma/COPD clinics in primary care could be beneficial while improving practices of patient education that enhance patients' ability to cope with the disease.KEY POINTSIssues vital for coping with chronic obstructive pulmonary disease (COPD), such as psychological well-being, stress and fatigue, are irregularly included in self-management education both in primary and specialised healthcare.Patient education provided by asthma/COPD nurses is more regular than patient education provided by other nurses.The distribution of work between doctors and nurses should be considered to ensure that there is no gap in COPD patients' education.

Symptom Clusters and Health-related Quality of Life in Chinese patients with Chronic Obstructive Pulmonary Disease

This study aimed to identify symptom clusters of chronic obstructive pulmonary disease (COPD) and to examine the relationship between symptom clusters and health-related quality of life (HRQoL). It included 154 hospitalized patients with COPD. The majority of the participants (88.6%) were aged 60 years and above, and the numbers of men and women were approximately equal (men: 55.2%). The Charlson Comorbidity Index (CCI), the Memorial Symptom Assessment Scale (MSAS), and the Chinese version of the Clinical COPD Questionnaire (CCQ) were used to evaluate comorbidity, participant's symptoms, and HRQoL, respectively. Five symptom clusters were identified using exploratory factor analysis, and symptom clusters, especially the Psychological, Pain and Fatigue, GI, and Dyspnea-Sweat symptom clusters, had negative effects on HRQoL in patients with COPD. Understanding the patterns and occurrences of symptom clusters could be essential for developing effective interventions to manage COPD symptoms and improve the patients' HRQoL.

Equal palliative care for patients with COPD? A nationwide register study

Background: Although chronic obstructive pulmonary disease (COPD) is a life-limiting disease with a significant symptom burden, the patients are more often referred to nursing homes (NH), than to specialist palliative care (SPC) at the end of life (EOL). This study aimed to compare patients with COPD in SPC with those in NH and to compare the care provided. Methods: A national register study was carried out where the Swedish National Airway Register and the Swedish Register of Palliative Care were merged. COPD patients who died in NHs or short-term facilities were included in the NH group (n = 415) and those who died in SPC were included in the SPC group (n = 355). Demographic and clinical variables were included from the Swedish National Airway Register and variables concerning EOL care from the Swedish Register of Palliative Care. Results: Symptom prevalence was similar in NHs and SPC, but symptom assessment (32% vs 20%), symptom relief medication (93-98% in SPC vs 74-90% in NH), EOL discussions (88% vs 66%), and bereavement support (94% vs 67%) were more likely in SPC (in all comparisons p < 0.001). Younger age and co-habiting increased the probability of dying in SPC (p < 0.001). Conclusion: Despite similar symptom prevalence, older persons are more likely to be referred to NHs. If applying a palliative care philosophy in NHs, routine symptom assessment and prescription of rescue medication for frequent symptoms, would be more likely. Promoting advance care planning and EOL discussions at an earlier stage would result in more prepared patients and families.

Systematic Review of Pain in Clinical Practice Guidelines for Management of COPD: A Case for Including Chronic Pain?

Chronic pain is highly prevalent and more common in people with chronic obstructive pulmonary disease (COPD) than people of similar age/sex in the general population. This systematic review aimed to describe how frequently and in which contexts pain is considered in the clinical practice guidelines (CPGs) for the broad management of COPD. Databases (Medline, Scopus, CiNAHL, EMbase, and clinical guideline) and websites were searched to identify current versions of COPD CPGs published in any language since 2006. Data on the frequency, context, and specific recommendations or strategies for the assessment or management of pain were extracted, collated, and reported descriptively. Of the 41 CPGs (English n = 20) reviewed, 16 (39%) did not mention pain. Within the remaining 25 CPGs, pain was mentioned 67 times (ranging from 1 to 10 mentions in a single CPG). The most frequent contexts for mentioning pain were as a potential side effect of specific pharmacotherapies (22 mentions in 13 CPGs), as part of differential diagnosis (14 mentions in 10 CPGs), and end of life or palliative care management (7 mentions in 6 CPGs). In people with COPD, chronic pain is common; adversely impacts quality of life, mood, breathlessness, and participation in activities of daily living; and warrants consideration within CPGs for COPD.

Symptom clusters in chronic obstructive pulmonary disease: A systematic review

AIM

To conduct a comprehensive literature review to identify symptom clusters commonly present in Chronic obstructive pulmonary disease (COPD) patients.

BACKGROUND

COPD is the fourth leading cause of death worldwide. Substantial research has been studied regarding single symptoms that burden patients with this disease and the profound impacts that these symptoms can have on physical and psychological health. However, these symptoms rarely occur in isolation and limited research has been conducted identifying clinically significant relationships or clusters of symptoms associated with COPD afflicted patients.

METHODS

PubMed, Web of Science, and Embase databases were used to identify potential articles limited to records published between 2005 and 2018 with human-conducted trials on adults with COPD, examining symptom clusters in this population. Only 5 studies met inclusion criteria.

RESULTS

Across the five studies, 596 participants were included with a mean age of 70.49. Two themes emerged including psychological symptom clusters and respiratory-related symptom clusters. Anxiety-related symptoms appeared to be a common theme among psychological symptom clusters and varied greatly based on instrument selection. Inconsistent results were found in respiratory-related symptom clusters, but included difficulty breathing as a common symptom component. Only one study examined for stability of symptoms over time.

CONCLUSION

There were inconsistent results across all studies which may be contributed to the heterogeneity amongst patients, instruments administered, and statistical approach. Future research should be conducted to further elucidate COPD related symptom clusters, their effects on somatic and cognitive health, and the stability of these symptom clusters over time.

Palliative Care Competencies and Readiness for Independent Practice: A Report on the American Academy of Hospice and Palliative Medicine Review of the U.S. Medical Licensing Step Examinations

CONTEXT

It is unknown whether the palliative care (PC) content tested in the U.S. Medical Licensing Examination (USMLE) step examinations reflects the consensus-developed PC competencies.

OBJECTIVES

To review the USMLE step examinations to determine whether they test the PC knowledge necessary for graduating medical students and residents applying for licensure.

METHODS

Eight PC physicians reviewed three complete examination forms and a focused 509-item bundle of multiple-choice questions (MCQs) identified by the USMLE content outline as potentially assessing PC content. Reviewers determined MCQs to be PC items if the patient was seriously ill and PC knowledge was required to answer correctly. PC items' competency domains were determined using reference domains from PC subspecialty consensus competencies.

RESULTS

Reviewers analyzed 1090 MCQs and identified 242 (22%) as PC items. PC items were identified in each step examination. Patients in PC items were mostly males (62.8%), older than 65 years (62%), and diagnosed with cancer (43.6%). Only 6.6% and 6.2%, respectively, had end-stage heart disease or multimorbid illness. Fifty-one percent of PC items addressed ethics (31%) or communication (19.8%), focusing on patient autonomy, surrogate decision makers, or conflict between decision makers. Pain and symptom management was assessed in 28.5% of PC items, and one-third of those addressed addiction or substance use disorder.

CONCLUSION

We identified PC content in each step examination. However, heart disease and multimorbidity were under-represented in PC items relative to their prevalence. In addition, there was heavy overlap with ethics, a focus on conflict in assessing communication skills, and emphasis on addiction when testing pain management. Our findings highlight opportunities to enhance testing of clinical PC skills essential for all licensed physicians practicing medicine.

Test-retest and inter-rater reliability of the Danish version of the management of everday technology assessment for use with older adults with and without COPD

BACKGROUND

The trend towards telemedicine increasingly requires clients to manage everyday technology (ET) to access and use health services. The Management of Everday Technology Assessment (META) is an observation-based instrument developed to evaluate the ability to manage ET.

AIM

To examine test-retest (TRR) and inter-rater reliability (IRR) of the Danish translation of the META for older adults with and without COPD.

METHOD AND MATERIALS

47 older adults with COPD (n = 23) and without (n = 24) were recruited. IRR was examined by four raters paired across 30 participants. TRR was examined for 21 participants by the same rater administering the META twice within four weeks. A rank-based method for paired ordinal data was used to calculate percentage agreement (PA) and measures of systematic disagreement and individual variability. Mann Whitney U tests were used to compare PA to health status (presence/absence of COPD).

RESULTS

Inter-rater PA was acceptable across 10 of 11 items and test-retest PA across 8 of 11 items. Systematic disagreement was present for one item in TRR. No significant differences in PA were found regarding health status.

CONCLUSION

The Danish META generates reliable scores for this sample. However, conclusive statements cannot be made for all items.

Reliability and validity of the Brief Pain Inventory in individuals with chronic obstructive pulmonary disease

BACKGROUND

Pain is prevalent in chronic obstructive pulmonary disease (COPD) and the Brief Pain Inventory (BPI) appears to be a feasible questionnaire to assess this symptom. However, the reliability and validity of the BPI have not been determined in individuals with COPD. This study aimed to determine the internal consistency, test-retest reliability and validity (construct, convergent, divergent and discriminant) of the BPI in individuals with COPD.

METHODS

In order to examine the test-retest reliability, individuals with COPD were recruited from pulmonary rehabilitation programmes to complete the BPI twice 1 week apart. In order to investigate validity, de-identified data was retrieved from two previous studies, including forced expiratory volume in 1-s, age, sex and data from four questionnaires: the BPI, short-form McGill Pain Questionnaire (SF-MPQ), 36-Item Short Form Survey (SF-36) and Community Health Activities Model Program for Seniors (CHAMPS) questionnaire.

RESULTS

In total, 123 participants were included in the analyses (eligible data were retrieved from 86 participants and additional 37 participants were recruited). The BPI demonstrated excellent internal consistency and test-retest reliability. It also showed convergent validity with the SF-MPQ and divergent validity with the SF-36. The factor analysis yielded two factors of the BPI, which demonstrated that the two domains of the BPI measure the intended constructs. The BPI can also discriminate pain levels among COPD patients with varied levels of quality of life (SF-36) and physical activity (CHAMPS).

CONCLUSION

The BPI is a reliable and valid pain questionnaire that can be used to evaluate pain in COPD.

SIGNIFICANCE

This study formally established the reliability and validity of the BPI in individuals with COPD, which have not been determined in this patient group. The results of this study provide strong evidence that assessment results from this pain questionnaire are reliable and valid.

Prevalence of anxiety and depression symptoms and their associated factors in mild COPD patients from community settings, Shanghai, China: a cross-sectional study

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is a serious disease frequently accompanied by anxiety and depression. Few studies have focused on anxiety and depression for mild COPD patients in China. This study aimed to assess the prevalence and associated factors for anxiety and depression among patients with mild COPD in urban communities.

METHODS

A cross-sectional survey of 275 mild COPD patients was conducted in 6 communities randomly sampled from Pudong New Area of Shanghai, China, in 2016. Data on socioeconomic factors and health conditions were acquired through a face-to-face interview as well as a physical examination. The Hospital Anxiety and Depression Scale (HAD) and EQ-5D visual analogue (EQ-5Dvas) were applied to evaluate their mental health and quality of life, respectively. Logistic regression model was used to estimate adjusted odds ratios (aORs) and their 95% confidential intervals (CI) for risk factors associated with anxiety or depression.

RESULTS

Among 275 subjects, 8.1% had anxiety and 13.4% had depression. Logistic regression analysis indicated that female patients were more likely to suffer from anxiety than male patients (aOR = 6.41, 95% CI:1.73-23.80). Poor health status (EQ-5Dvas score < 70) was significantly associated with increased risks of anxiety (aOR = 5.99, 95% CI: 2.13-16.82) and depression (aOR = 2.67, 95% CI: 1.29-5.52).

CONCLUSIONS

There were increased risks of anxiety and depression in mild COPD patients living in urban communities. Female sex and poor health status were significantly correlated to anxiety or depression. More interventions should be developed to reduce the risks of anxiety and depression at the early stage of COPD.

Effect of symptoms on physical performance in COPD

BACKGROUND

Chronic obstructive pulmonary disease (COPD) patients experience multiple symptoms including dyspnea, anxiety, depression, and fatigue, which are highly correlated with each other. Together, those symptoms may contribute to impaired physical performance.

OBJECTIVES

The purpose of this study was to examine interrelationships among dyspnea, anxiety, depressive symptoms, and fatigue as contributing factors to physical performance in COPD.

METHODS

This study used baseline data of 282 COPD patients from a longitudinal observational study to explore the relationship between depression, inflammation, and functional status. Data analyses included confirmatory factor analyses and structural equation modeling.

RESULTS

Dyspnea, anxiety and depression had direct effects on fatigue, and both dyspnea and anxiety had direct effects on physical performance. Higher levels of dyspnea were significantly associated with impaired physical performance whereas higher levels of anxiety were significantly associated with enhanced physical performance.

CONCLUSION

Dyspnea was the strongest predictor of impaired physical performance in patients with COPD.

Role of inspiratory capacity on dyspnea evaluation in COPD with or without emphysematous lesions: a pilot study

Background

Since forced expiratory volume in 1 second (FEV₁) shows a weak correlation with patients’ symptoms in COPD, some volume parameters may better reflect the change in dyspnea symptoms after treatment. In this article, we investigated the role of inspiratory capacity (IC) on dyspnea evaluation among COPD patients with or without emphysematous lesions.

Methods

In this prospective study, 124 patients with stable COPD were recruited. During the baseline visit, patients performed pulmonary function tests and dyspnea evaluation using the modified Medical Research Council (mMRC) scale. Partial patients underwent quantitative computerized tomography scans under physicians’ recommendations, and emphysematous changes were assessed using the emphysema index (EI; low attenuation area [LAA]% −950). These subjects were then divided into the emphysema-predominant group (LAA% −950≥9.9%) and the non-emphysema-predominant group (LAA% −950<9.9%). After treatment for ~1 month, subjects returned for reevaluation of both pulmonary function parameters and dyspnea severity. Correlation analysis between the change in IC (ΔIC) and dyspnea (ΔmMRC) was performed.

Results

Correlation analysis revealed that ΔIC was negatively correlated with ΔmMRC (correlation coefficient [cc], −0.490, P<0.001) in the total study population, which was stronger than that between ΔFEV₁ and ΔmMRC (cc, −0.305, P=0.001). Patients with absolute ΔmMRC >1 were more likely to exhibit a marked increase in IC (≥300 mL) than those with absolute ΔmMRC ≤1 (74.36% versus 35.29%; odds ratio [OR], 5.317; P<0.001). In the emphysema-predominant group, only ΔIC strongly correlated with ΔmMRC (cc, −0.459, P=0.005), while ΔFEV₁ did not (P>0.05).

Conclusion

IC could serve as an effective complement to FEV₁ in COPD patients undergoing dyspnea evaluation after treatment. For COPD patients with predominant emphysematous lesions, an increase in IC is particularly more suitable for explaining dyspnea relief than FEV₁.

Advancing Symptom Science Through Symptom Cluster Research: Expert Panel Proceedings and Recommendations

An overview of proceedings, findings, and recommendations from the workshop on "Advancing Symptom Science Through Symptom Cluster Research" sponsored by the National Institute of Nursing Research (NINR) and the Office of Rare Diseases Research, National Center for Advancing Translational Sciences, is presented. This workshop engaged an expert panel in an evidenced-based discussion regarding the state of the science of symptom clusters in chronic conditions including cancer and other rare diseases. An interdisciplinary working group from the extramural research community representing nursing, medicine, oncology, psychology, and bioinformatics was convened at the National Institutes of Health. Based on expertise, members were divided into teams to address key areas: defining characteristics of symptom clusters, priority symptom clusters and underlying mechanisms, measurement issues, targeted interventions, and new analytic strategies. For each area, the evidence was synthesized, limitations and gaps identified, and recommendations for future research delineated. The majority of findings in each area were from studies of oncology patients. However, increasing evidence suggests that symptom clusters occur in patients with other chronic conditions (eg, pulmonary, cardiac, and end-stage renal disease). Nonetheless, symptom cluster research is extremely limited and scientists are just beginning to understand how to investigate symptom clusters by developing frameworks and new methods and approaches. With a focus on personalized care, an understanding of individual susceptibility to symptoms and whether a "driving" symptom exists that triggers other symptoms in the cluster is needed. Also, research aimed at identifying the mechanisms that underlie symptom clusters is essential to developing targeted interventions.

Approaches to daily body condition management in patients with stable chronic obstructive pulmonary disease

AIM AND OBJECTIVE

To clarify the characteristics of sub-groups of patients with stable chronic obstructive pulmonary disease having similar approaches to daily body condition management.

BACKGROUND

Prior literature has shed light on the experience of patients with chronic obstructive pulmonary disease and revealed that these patients engage in many activities and try different things in their daily lives to regulate and manage their body condition. The research so far has all been qualitative, comprising mostly interviews, and no quantitative studies have been performed. In this study, cluster analysis was used to show that subgroups of patients with similar characteristics undertake similar approaches to body condition management.

DESIGN

Descriptive, correlational study.

METHODS

Invitations to participate in the survey were extended to patients with stable chronic obstructive pulmonary disease. Cluster analysis was performed on the basis of questionnaire scores relating to nine different categories of daily body condition management actions. The characteristics of the body condition management approaches, in each subgroup, were investigated using analysis of variance and multiple comparisons.

RESULTS

The cluster analysis produced six subgroups, each defined by the effort expended as part of their body condition management. The subgroups also differed depending on patient age and disease severity.

CONCLUSION

Body condition management approaches taken by patients with stable chronic obstructive pulmonary disease are overall, comprehensive approaches.

RELEVANCE TO CLINICAL PRACTICE

Patients with chronic obstructive pulmonary disease were subgrouped based on their engagement in body conditioning. Relationships between the subgroups and the engagement in body conditioning, age and shortness of breath severity were observed. The care of patient support should be comprehensive and depend on their age and the duration of the disease. In addition, it should be long term and recognise that the patients are living their own respective lives. Such considerations and focused perspectives are what we think will lead to an improvement in patients' quality of life and prevent their condition from worsening.

Distinct symptom experiences in subgroups of patients with COPD

Background

In addition to their respiratory symptoms, patients with COPD experience multiple, co-occurring symptoms.

Objectives

The aims of this study were to identify subgroups of COPD patients based on their distinct experiences with 14 symptoms and to determine how these subgroups differed in demographic and clinical characteristics and disease-specific quality of life.

Patients and methods

Patients with moderate, severe, and very severe COPD (n=267) completed a number of self-report questionnaires. Latent class analysis was used to identify subgroups of patients with distinct symptom experiences based on the occurrence of self-reported symptoms using the Memorial Symptom Assessment Scale.

Results

Based on the probability of occurrence of a number of physical and psychological symptoms, three subgroups of patients (ie, latent classes) were identified and named “high”, “intermediate”, and “low”. Across the three latent classes, the pairwise comparisons for the classification of airflow limitation in COPD were not significantly different, which suggests that measurements of respiratory function are not associated with COPD patients’ symptom burden and their specific needs for symptom management. While patients in both the “high” and “intermediate” classes had high occurrence rates for respiratory symptoms, patients in the “high” class had the highest occurrence rates for psychological symptoms. Compared with the “intermediate” class, patients in the “high” class were younger, more likely to be women, had significantly more acute exacerbations in the past year, and reported significantly worse disease-specific quality of life scores.

Conclusion

These findings suggest that subgroups of COPD patients with distinct symptom experiences can be identified. Patients with a higher symptom burden warrant more detailed assessments and may have therapeutic needs that would not be identified using current classifications based only on respiratory function.

Symptom trajectory and symptom burden in older people with multimorbidity, secondary outcome from the RCT AGe-FIT study

AIM

The aim of this study was to follow the symptom trajectory of community-dwelling older people with multimorbidity and to explore the effect on symptom burden from an ambulatory geriatric care unit, based on comprehensive geriatric assessment.

BACKGROUND

Older community-dwelling people with multimorbidity suffer from a high symptom burden with a wide range of co-occurring symptoms often resulting to decreased health-related quality of life. There is a need to move from a single-disease model and address the complexity of older people living with multimorbidity.

DESIGN

Secondary outcome data from the randomized controlled Ambulatory Geriatric Assessment Frailty Intervention Trial (AGe-FIT).

METHODS

Symptom trajectory of 31 symptoms was assessed with the Memorial Symptom Assessment Scale. Data from 247 participants were assessments at baseline, 12 and 24 months, 2011-2013. Participants in the intervention group received care from an ambulatory geriatric care unit based on comprehensive geriatric assessment in addition to usual care.

RESULTS

Symptom prevalence and symptom burden were high and stayed high over time. Pain was the symptom with the highest prevalence and burden. Over the 2-year period 68-81% of the participants reported pain. Other highly prevalent and persistent symptoms were dry mouth, lack of energy and numbness/tingling in the hands/feet, affecting 38-59% of participants. No differences were found between the intervention and control group regarding prevalence, burden or trajectory of symptoms.

CONCLUSIONS

Older community-dwelling people with multimorbidity had a persistent high burden of symptoms. Receiving advanced interdisciplinary care at an ambulatory geriatric unit did not significantly reduce the prevalence or the burden of symptoms.

Differences in Symptom Burden Among Patients With Moderate, Severe, or Very Severe Chronic Obstructive Pulmonary Disease

CONTEXT

The symptom experience of patients with chronic obstructive pulmonary disease (COPD) is extremely complex. It is characterized by multiple co-occurring symptoms. However, very few studies have described this experience in COPD patients.

OBJECTIVES

The aims of this study were to evaluate for differences in symptom occurrence rates, as well as ratings of symptom severity, frequency, and distress among patients (n = 267) with moderate, severe, and very severe COPD.

METHODS

The Memorial Symptom Assessment Scale was used to evaluate the multiple dimensions of the patient's symptom experience. Binary and ordinal logistic regression analyses with stage of disease as an ordinal predictor variable were used to evaluate for differences in symptom occurrence rates and ratings of symptom severity, frequency, and distress.

RESULTS

Regardless of the severity of their disease, patients reported an average of 12 co-occurring symptoms. Shortness of breath and lack of energy were the only two symptoms that differed significantly among the three disease severity groups in terms of occurrence, severity, frequency, and distress. Patients with very severe COPD reported the highest ratings for shortness of breath and lack of energy across all four symptom dimensions.

CONCLUSION

Regardless of stage of disease, the high symptom burden identified in this study underscores the need for COPD patients to be screened for multiple co-occurring symptoms.

Occurrence, Characteristics, and Predictors of Pain in Patients with Chronic Obstructive Pulmonary Disease

Few studies have provided a detailed characterization of pain in patients with chronic obstructive pulmonary disease (COPD). The aims of this cross-sectional study were to describe the occurrence, intensity, locations, and level of interference associated with pain, as well as pain relief; to identify differences in demographic, clinical, and symptom characteristics between COPD patients with and without pain; and to determine which demographic, clinical, and symptom characteristics were associated with average pain, worst pain, and pain interference. A total of 258 patients with COPD provided information on demographic characteristics; comorbidities; respiratory parameters including dyspnea; body mass index; and symptom characteristics (i.e., anxiety, depression, sleep disturbance, and fatigue). Pain was measured using the Brief Pain Inventory. Of these 258 COPD patients, 157 (61%) reported pain. Multiple linear regression analyses were performed to determine which demographic, clinical, and symptom characteristics were associated with average pain severity, worst pain severity, and mean pain interference. Lower stages of COPD were associated with higher worst pain and higher pain interference scores. Higher depression scores were associated with higher average pain and higher pain interference scores. In addition, higher number of pain locations was associated with higher average and higher worst pain severity scores. Findings from this study confirm that pain is a significant problem and highlights the need for specific pain management interventions for patients with COPD. More research is needed about specific pain characteristics and symptoms to gain an increased knowledge about the causes of pain in these patients.

Cachexia in chronic obstructive pulmonary disease: new insights and therapeutic perspective

Cachexia and muscle wasting are well recognized as common and partly reversible features of chronic obstructive pulmonary disease (COPD), adversely affecting disease progression and prognosis. This argues for integration of weight and muscle maintenance in patient care. In this review, recent insights are presented in the diagnosis of muscle wasting in COPD, the pathophysiology of muscle wasting, and putative mechanisms involved in a disturbed energy balance as cachexia driver. We discuss the therapeutic implications of these new insights for optimizing and personalizing management of COPD-induced cachexia.

To adjust and endure: a qualitative study of symptom burden in older people with multimorbidity

CONTEXT

Older people with multimorbidity are vulnerable and often suffer from conditions that produce a multiplicity of symptoms and a reduced health-related quality of life.

OBJECTIVES

The aim of this study is to explore the experience of living with a high symptom burden from the perspective of older community-dwelling people with multi-morbidity.

METHOD

A qualitative descriptive design with semi-structured interviews, including 20 community-dwelling older people with multi-morbidity and a high symptom burden. The participants were 79-89 years old with a mean of 12 symptoms per person. Data were analyzed using content analyses.

RESULTS

The experience of living with a high symptom burden revealed the overall theme, "To adjust and endure" and three sub-themes. The first sub-theme was "To feel inadequate and limited". Participants reported that they no longer had the capacity or the ability to manage, and they felt limited and isolated from friends or family. The second sub-theme was "To feel dependent". This was a new and inconvenient experience; the burden they put on others caused a feeling of guilt. The final sub-theme was "To feel dejected". The strength to manage and control their conditions was gone; the only thing left to do was to sit or lie down and wait for it all to pass.

CONCLUSION

This study highlights the importance of a holistic approach when taking care of older people with multi-morbidity. This approach should employ a broad symptom assessment to reveal diseases and conditions that are possible to treat or improve.
