Self-management programmes for COPD: moving forward

Self-management is of increasing importance in chronic obstructive pulmonary disease (COPD) management. However, there is confusion over what processes are involved, how the value of self-management should be determined, and about the research priorities. To gain more insight into and agreement about the content of programmes, outcomes, and future directions of COPD self-management, a group of interested researchers and physicians, all of whom had previously published on this subject and who had previously collaborated on other projects, convened a workshop. This article summarises their initial findings. Self-management programmes aim at structural behaviour change to sustain treatment effects after programmes have been completed. The programmes should include techniques aimed at behavioural change, be tailored individually, take the patient’s perspective into account, and may vary with the course of the patient’s disease and co-morbidities. Assessment should include process variables. This report is a step towards greater conformity in the field of self-management. To enhance clarity regarding effectiveness, future studies should clearly describe their intervention, be properly designed and powered, and include outcomes that focus more on the acquisition and practice of new skills. In this way more evidence and a better comprehension on self-management programmes will be obtained, and more specific formulation of guidelines on self-management made possible.

Treatments for anxiety and depression in patients with chronic obstructive pulmonary disease: A literature review

Chronic obstructive pulmonary disease (COPD) is a serious contemporary health issue. Psychological co‐morbidities such as anxiety and depression are common in COPD. Current evidence for treatment options to reduce anxiety and depression in patients with COPD was examined. There is evidence available for the efficacy of pharmacological treatments, cognitive behavioural therapy, pulmonary rehabilitation, relaxation therapy and palliative care in COPD. Therapeutic modalities that have not been proven effective in decreasing anxiety and depression in COPD, but which have theoretical potential among patients, include interpersonal psychotherapy, self‐management programmes, more extensive disease management programmes, supportive therapy and self‐help groups. Besides pulmonary rehabilitation that is only available for a small percentage of patients, management guidelines make scant reference to other options for the treatment of mental health problems. The quantity and quality of research on mental health treatments in COPD have historically been insufficient to support their inclusion in COPD treatment guidelines. In this review, recommendations regarding assessment, treatment and future research in this important field were made.

CommentaryDefinitions of Exacerbations: Does It Really Matter in Clinical Trials on COPD?

Many definitions of COPD exacerbations are reported. The choice for a definition determines the number of exacerbations observed. However, the effect of different definitions on the effect sizes of randomized controlled trials is unclear. This article provides an overview of the large variation of definitions of COPD exacerbations from the literature. Furthermore, the effect of using different definitions on effect sizes (relative risk and hazard ratio) was investigated in a randomized controlled discontinuation trial of inhaled corticosteroids. The following definitions were applied: (1) unscheduled medical attention, (2) a course of oral corticosteroids/antibiotics, (3) deterioration in two major or one major and one minor symptom according to Anthonisen (referenced later), (4) a change in one or more symptoms, (5) a change in two or more symptoms, and (6) a combination of numbers 2 and 4. Relative risks for the exacerbation rate ranged from 1.19 to 1.49, and hazard ratios for time to first exacerbation ranged from 1.36 to 1.84 for the various definitions, varying from nonsignificant to significant. Because the definition of a COPD exacerbation has an impact on the effect size of interventions, there is an urgent need for concerted attempts to reach agreement on a definition of an exacerbation. Also, the exact definition to be used in a study should be specified in the protocol.

A self-management approach using self-initiated action plans for symptoms with ongoing nurse support in patients with Chronic Obstructive Pulmonary Disease (COPD) and comorbidities: The COPE-III study protocol

BACKGROUND Chronic Obstructive Pulmonary Disease (COPD) frequently coexists with other diseases. Whereas COPD action plans are currently part of usual care, they are less suitable and potentially unsafe for use in the presence of comorbidities. This study evaluates whether an innovative treatment approach directed towards COPD and frequently existing comorbidities can reduce COPD exacerbation days. We hypothesise that this approach, which combines self-initiated action plans and nurse support, will accelerate proper treatment actions and lead to better control of deteriorating symptoms. METHODS In this multicenter randomised controlled trial we aim to include 300 patients with COPD (GOLD II-IV), and with at least one comorbidity (cardiovascular disease, diabetes, anxiety and/or depression). Patients will be recruited from hospitals in the Netherlands (n = 150) and Australia (n = 150) and will be assigned to an intervention or control group. All patients will learn to complete daily symptom diaries for 12-months. Intervention group patients will participate in self-management training sessions to learn the use of individualised action plans for COPD and comorbidities, linked to the diary. The primary outcome is the number of COPD exacerbation days. Secondary outcomes include hospitalisations, quality of life, self-efficacy, adherence, patients satisfaction and confidence, health care use and cost data. ANALYSES Intention-to-treat analyses (random effect negative binomial regression and random effect mixed models) and cost-effectiveness analyses will be performed. DISCUSSION Prudence should be employed before extrapolating the use of COPD specific action plans in patients with comorbidities. This study evaluates the efficacy of tailored action plans for both COPD and common comorbidities.

Do self-management interventions in COPD patients work and which patients benefit most? An individual patient data meta-analysis

Background Self-management interventions are considered effective in patients with COPD, but trials have shown inconsistent results and it is unknown which patients benefit most. This study aimed to summarize the evidence on effectiveness of self-management interventions and identify subgroups of COPD patients who benefit most. Methods Randomized trials of self-management interventions between 1985 and 2013 were identified through a systematic literature search. Individual patient data of selected studies were requested from principal investigators and analyzed in an individual patient data meta-analysis using generalized mixed effects models. Results Fourteen trials representing 3,282 patients were included. Self-management interventions improved health-related quality of life at 12 months (standardized mean difference 0.08, 95% confidence interval [CI] 0.00–0.16) and time to first respiratory-related hospitalization (hazard ratio 0.79, 95% CI 0.66–0.94) and all-cause hospitalization (hazard ratio 0.80, 95% CI 0.69–0.90), but had no effect on mortality. Prespecified subgroup analyses showed that interventions were more effective in males (6-month COPD-related hospitalization: interaction P=0.006), patients with severe lung function (6-month all-cause hospitalization: interaction P=0.016), moderate self-efficacy (12-month COPD-related hospitalization: interaction P=0.036), and high body mass index (6-month COPD-related hospitalization: interaction P=0.028 and 6-month mortality: interaction P=0.026). In none of these subgroups, a consistent effect was shown on all relevant outcomes. Conclusion Self-management interventions exert positive effects in patients with COPD on respiratory-related and all-cause hospitalizations and modest effects on 12-month health-related quality of life, supporting the implementation of self-management strategies in clinical practice. Benefits seem similar across the subgroups studied and limiting self-management interventions to specific patient subgroups cannot be recommended.

Construct Validity of the Dutch Version of the 12-Item Partners in Health Scale: Measuring Patient Self-Management Behaviour and Knowledge in Patients with Chronic Obstructive Pulmonary Disease

Objective The 12-item Partners in Health scale (PIH) was developed in Australia to measure self-management behaviour and knowledge in patients with chronic diseases, and has undergone several changes. Our aim was to assess the construct validity and reliability of the latest PIH version in Dutch COPD patients. Methods The 12 items of the PIH, scored on a self-rated 9-point Likert scale, are used to calculate total and subscale scores (knowledge; coping; recognition and management of symptoms; and adherence to treatment). We used forward-backward translation of the latest version of the Australian PIH to define a Dutch PIH (PIH(Du)). Mokken Scale Analysis and common Factor Analysis were performed on data from a Dutch COPD sample to investigate the psychometric properties of the Dutch PIH; and to determine whether the four-subscale solution previously found for the original Australian PIH could be replicated for the Dutch PIH. Results Two subscales were found for the Dutch PIH data (n = 118); 1) knowledge and coping; 2) recognition and management of symptoms, adherence to treatment. The correlation between the two Dutch subscales was 0.43. The lower-bound of the reliability of the total scale equalled 0.84. Factor analysis indicated that the first two factors explained a larger percentage of common variance (39.4% and 19.9%) than could be expected when using random data (17.5% and 15.1%). Conclusion We recommend using two PIH subscale scores when assessing self-management in Dutch COPD patients. Our results did not support the four-subscale structure as previously reported for the original Australian PIH.

Counseling for health behavior change in people with COPD: systematic review

Counseling has been suggested as a promising approach for facilitating changes in health behavior. The aim of this systematic review of counseling interventions for people with COPD was to describe: 1) counseling definitions, 2) targeted health behaviors, 3) counseling techniques and 4) whether commonalities in counseling techniques were associated with improved health behaviors. Ten databases were searched for original randomized controlled trials which included adults with COPD, used the term “counseling” as a sole or component of a multifaceted intervention and were published in the previous 10 years. Data extraction, study appraisal and coding for behavior change techniques (BCTs) were completed by two independent reviewers. Data were synthesized descriptively, with meta-analysis conducted where possible. Of the 182 studies reviewed as full-text, 22 were included. A single study provided a definition for counseling. Two key behaviors were the main foci of counseling: physical activity (n=9) and smoking cessation (n=8). Six studies (27%) reported underlying models and/or theoretical frameworks. Counseling was the sole intervention in 10 studies and part of a multicomponent intervention in 12. Interventions targeting physical activity included a mean of 6.3 (±3.1) BCTs, smoking cessation 4.9 (±2.9) BCTs and other behaviors 6.5 (±3.9) BCTs. The most frequent BCTs were social support unspecified (n=22; 100%), goal setting behavior (n=11), problem-solving (n=11) and instructions on how to perform the behavior (n=10). No studies shared identical BCT profiles. Counseling had a significant positive effect for smoking cessation and positive but not significant effect for physical activity. Counseling for health behavior change was rarely defined and effectiveness varied by target behavior. Provision of specific details when reporting studies of counseling interventions (definition, BCTs, dosage) would allow clarification of the effectiveness of counseling as an approach to health behavior change in people with COPD.

Physical activity, sedentary behaviour and sleep in COPD guidelines: A systematic review:

Objectives: Physical activity, sedentary and sleep behaviours have strong associations with health. This systematic review aimed to identify how clinical practice guidelines (CPGs) for the management of chronic obstructive pulmonary disease (COPD) report specific recommendations and strategies for these movement behaviours. Methods: A systematic search of databases (Medline, Scopus, CiNAHL, EMbase, Clinical Guideline), reference lists and websites identified current versions of CPGs published since 2005. Specific recommendations and strategies concerning physical activity, sedentary behaviour and sleep were extracted verbatim. The proportions of CPGs providing specific recommendations and strategies were reported. Results: From 2370 citations identified, 35 CPGs were eligible for inclusion. Of these, 21 (60%) provided specific recommendations for physical activity, while none provided specific recommendations for sedentary behaviour or sleep. The most commonly suggested strategies to improve movement behaviours were encouragement from a healthcare provider (physical activity n = 20; sedentary behaviour n = 2) and referral for a diagnostic sleep study (sleep n = 4). Conclusion: Since optimal physical activity, sedentary behaviour and sleep durations and patterns are likely to be associated with mitigating the effects of COPD, as well as with general health and well-being, there is a need for further COPD-specific research, consensus and incorporation of recommendations and strategies into CPGs.

The (cost)-effectiveness of self-treatment of exacerbations on the severity of exacerbations in COPD patients: the COPE-II study

Background: Chronic obstructive pulmonary disease (COPD) is a chronic disease with a high prevalence and rapidly increasing incidence rates. The effect of self-treatment of COPD exacerbations on the severity of exacerbations during a 1-year period was examined and a cost-effectiveness analysis was performed. Methods: Patients were randomly allocated to four 2-hour self-management sessions, with or without training in self-treatment of exacerbations. Patients in the self-treatment group received an action plan with the possibility to initiate a course of prednisolone (with or without antibiotics). During follow-up, all participants kept a daily symptom diary. These provided the data to calculate the frequency of exacerbations, the number of exacerbation days and mean daily severity scores. Results: Data were analysed for 142 randomised patients (self-treatment: n = 70; control: n = 72). The frequency of exacerbations was identical in both study groups (mean (SD) 3.5 (2.7)). Patients in the self-treatment group reported fewer exacerbation days (median 31 (interquartile range (IQR) 8.9–67.5) in the self-treatment group vs 40 (IQR 13.3–88.2) in the control group; p = 0.064); the difference was significant in the group of patients with a high number of exacerbation days per year (>137 (90th percentile of the whole study population); p = 0.028). The mean severity score of an exacerbation day was equal in both groups. No between-group differences were found in health-related quality of life. Cost-effectiveness analyses showed that applying self-treatment saved €154 per patient, with a trend towards a lower probability for hospital admissions (0.20/patient/year in the self-treatment group vs 0.33/patient/year in the control group; p = 0.388) and a significant reduction of health care contacts (5.37/patient/year in the self-treatment group vs 6.51/patient/year in the control group; p = 0.043). Conclusion: Self-treatment of exacerbations incorporated in a self-management programme leads to fewer exacerbation days and lower costs.

Barriers for setting up a pulmonary rehabilitation program in the Eastern Province of Saudi Arabia.

Background: Pulmonary rehabilitation (PR) programs proven to be one of the most effective treatment options for respiratory diseases; yet, they are not well-established in hospitals in Saudi Arabia. Aim: To determine the main barriers for setting up PR programs in Saudi Arabia. Methods: A cross-sectional study was conducted in the Eastern Province of Saudi Arabia. Health care providers involved in treatment of chronic obstructive pulmonary disease (COPD) patients were recruited from 22 general government hospitals. Data were collected using questionnaires: Full version if they had heard about PR before the study, and a short version if they had not heard about PR before. Results: A total of 123 health care providers were recruited (physicians [n = 44], nurses [n = 49], and respiratory therapists/technicians [n = 30]). Only 3.2% of the recruited health care providers had heard about PR programs before. According to the health care providers, the main barriers for setting up PR programs were a lack of (1) hospital capacity (75.6%), (2) trained health care providers (72.4%), and (3) funds (48.0%). There were significant differences in barriers reported by the health care providers. Compared to physicians, nurses were more likely to nominate the PR costs as a barrier (18.0% vs. 38.8%; P < 0.05). Conclusion: There is a worrisome lack of knowledge regarding content and benefits of PR programs among Saudi health care providers treating COPD patients. These findings imply that improving awareness and increasing education of the health care providers regarding PR will be required before PR can be more widely implemented as an integral treatment modality for patients with COPD in Saudi Arabia.
