Self-management strategies in chronic obstructive pulmonary disease

Effects of Tai Chi on Lung Function, Exercise Capacity and Psychosocial Outcomes in Patients With Chronic Obstructive Pulmonary Disease: Systematic Review and Meta-analysis of Randomized Controlled Trials

Objectives: To explore whether tai chi can improve lung function, exercise capacity, and health-related outcomes in patients with chronic obstructive pulmonary disease (COPD). Methods: The PubMed, Embase, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure (CNKI), Wanfang, and China Science and Technology Journal Database (VIP) databases were searched from inception to January 5, 2023. The methodological quality of the included studies was evaluated according to the Cochrane Handbook for Systematic Reviews of Interventions criteria. Results: A total of 1430 participants from 20 randomized controlled trials were included in this review. The results indicated significant effects of tai chi on FEV1, 6WMD, anxiety, and quality of life (p < 0.01), but not on FEV1%, FEVI/FVC, depression, and social support. Conclusions: Tai chi might be a potential alternative therapy to improve FEV1, 6WMD, anxiety, and quality of life for patients with COPD.

Non-Pharmacological Treatments of Asthma Chronic Obstructive Pulmonary Disease Overlap and Rehabilitation Programs

Non-pharmacologic treatment is a vital, yet often under-utilized aspect of care for patients with ACO. As patients with ACO are often excluded from clinical trials, management decisions should be based on patient characteristic "phenotypes," such as dyspnea or exacerbation, and considering whether COPD or asthma is more pronounced in the individual patient. Self-management interventions in asthma and COPD have an overwhelming amount of supporting evidence and should be an integral part of ACO management. Additionally, pulmonary rehabilitation has widespread benefits in patients with COPD as well as asthma and should be offered in symptomatic patients with ACO. While the COVID-19 pandemic has highlighted some shortcomings, and introduced several challenges, to the delivery of PR world-wide, it has also presented the opportunity for the development and refinement of new models to deliver PR, such as telerehabilitation. While further research and development are necessary, telerehabilitation offers a promising alternative to reach patients, such as those with ACO, who would benefit from the programming. While future research is needed, we can make a more explicit and judicious use of current best evidence in making therapeutic decisions that includes non-pharmacological interventions in patients with ACO.

eHealth in Self-Managing at a Distance Patients with COPD

Worldwide, healthcare delivery for chronic diseases has been challenging due to the current SARS-COV-2 pandemic. The growing use of information and communication technologies via telehealth has gained popularity in all fields of medicine. In chronic respiratory diseases, self-management, defined as a structured but personalized multi-component intervention with the main goal of achieving healthy behavioral change, is an essential element of long-term care. Iterative interventions delivered by a well-trained health coach in order to empower and provide the patient with the tools and skills needed to adopt sustained healthy behaviors have proven to be effective in chronic obstructive pulmonary disease (COPD). Benefits have been shown to both improve patient quality of life and reduce acute exacerbation events and acute healthcare utilization. In COPD, the evidence so far has shown us that remote technologies such as telemonitoring or remote management may improve patient-reported outcomes and healthcare utilization. However, clear limitations are still present and questions remain unanswered. More and better designed studies are therefore necessary to define the place of eHealth in self-managing at a distance in patients with COPD.

Developing a Web Platform to Optimize the Self-Management of People Living with a Chronic Respiratory Disease

Purpose: The purpose of this article is to describe the development of a new Web platform to optimize self-management after pulmonary rehabilitation (PR) for persons living with a chronic respiratory disease (CRD) and to present data on its usability. Method: The Web platform is informed by a theoretical framework of behaviour changes and concepts of self-management and self-efficacy. It uses breathing exercises and a logbook and is meant to be a self-management tool. Usability was tested for 8 months after PR with a group consisting of five patients with chronic obstructive pulmonary disease and one with pulmonary fibrosis. We evaluated adherence (e.g., number of exercise/weeks), quality of life, dyspnoea, and functional capacity. We measured frequency count for adherence and pre-post differences per patient for clinical outcomes. Results: Four participants' adherence was higher than 50% of completed exercises (72 exercise/weeks). Five of six participants showed maintenance of functional capacity (6-minute walk test) 8 months after PR. Four participants showed maintenance of their quality of life. Four participants showed a deterioration in dyspnoea on the Borg Scale of Perceived Exertion. Conclusions: We developed a new theory-informed Web platform to optimize self-management after PR for persons living with a CRD. The pilot Web platform appears to optimize adherence to self-management techniques and possibly stabilize people's health outcomes.

Telerehabilitation for Post-Hospitalized COVID-19 Patients: A Proof-of-Concept Study During a Pandemic

Purpose

Telerehabilitation could prevent sequelae from COVID-19. We aimed to assess the feasibility of telerehabilitation; describe pulmonary and functional profiles of COVID-19 patients; and explore the effect of telerehabilitation on improving pulmonary symptoms and quality of life.

Methods

We conducted a pre-experimental, pre-post pilot study. We recruited COVID-19 patients who had returned home following hospitalization. The intervention included eight weeks of supervised physiotherapy sessions. We documented technological issues, success of recruitment strategies, and participants' attendance to supervised sessions. We measured the impact of pulmonary symptoms on quality of life and functional health.

Results

We scheduled 64 supervised sessions with seven participants with few technological issues. Initial scores showed that pulmonary symptoms moderately to highly impacted quality of life. At eight weeks, all patients had improved from 10 to 45 points on the EuroQol-Visual Analog Scale (EQ-VAS) instrument, indicating clinical significance.

Conclusion

We developed and administered a telerehabilitation intervention during a global pandemic that targets key symptoms of the relevant disease.

Pulmonary Rehabilitation

Pulmonary rehabilitation (PR) is an essential intervention in the management of patients with chronic obstructive pulmonary disease. To guide health care professionals in the implementation and evaluation of a PR program, this article discusses the current key concepts regarding exercise testing, prescription, and training, as well as self-management intervention as essential parts of PR and post-rehabilitation maintenance. Moreover, new approaches (alternative forms of organization and delivery, tele-rehabilitation, exercise adjuncts) and unique and challenging situations (patients experiencing acute exacerbations, advanced disease) are thoroughly reviewed. Finally, validated point-of-care resources and online tools are provided.

Effectiveness of nursing interventions for breathlessness in people with chronic obstructive pulmonary disease: A systematic review and meta-analysis

AIM

To critically review and synthesize the findings of studies that evaluated the effectiveness of nursing interventions for improving breathlessness in adults with chronic obstructive pulmonary disease.

BACKGROUND

Systematic reviews of nursing interventions for breathlessness in people with chronic obstructive pulmonary disease have not been specifically addressed.

DESIGN

Systematic review with meta-analysis.

DATA SOURCES

A systematic search of Medline, CINAHL, PsycINFO and Embase was performed for studies published between January 2000 and June 2017.

REVIEW METHODS

Risk of bias, data extraction and meta-analysis were conducted using Cochrane methodology. The quality of evidence was assessed using the GRADE approach.

RESULTS

Twenty papers were included. A meta-analysis of interventions performed at home, including two trials, showed a significant effect in favour of experimental groups for the symptom score of the St. George Respiratory Questionnaire compared with controls. A meta-analysis of interventions performed in clinics with home follow-up showed a significant effect in favour of experimental groups for the mastery and fatigue scores of the Chronic Respiratory Questionnaire compared with controls. In this category of intervention, an additional meta-analysis showed a significant effect in favour of experimental groups for the symptom, activity and total scores of the St. George Respiratory Questionnaire compared with controls. The quality of evidence was assessed to be very low to moderate.

CONCLUSION

The results are equivocal as to whether nursing interventions performed at home and nursing interventions performed in hospital with follow-up improve breathlessness in people with chronic obstructive pulmonary disease.

The Effect of Pulmonary Rehabilitation in Mountain Environment on Exercise Capacity and Quality of Life in Patients with Chronic Obstructive Pulmonary Disease (COPD) and Chronic Bronchitis

BACKGROUND We aimed to test the effectiveness of the pulmonary rehabilitation in a mountain environment on the pulmonary function, physical performance, dyspnea, affective factors, and quality of life (QoL) in patients with chronic obstructive pulmonary disease (COPD) and chronic bronchitis (CB), as well as to determine predictors of clinical improvement. MATERIAL AND METHODS 128 consecutive patients (90 diagnosed with COPD and 38 diagnosed with CB) underwent comprehensive pulmonary rehabilitation for a duration of 3 weeks in one of 3 mountain health resorts in the High Tatras. The examination included spirometry (FEV1 and FEV1/FVC), 6-minute walk test (6MWT), Borg scale of dyspnea, and assessment of depression (Zung score), anxiety (Beck score), and QoL using the SF-36 scales. RESULTS After the study intervention, all patients in both monitored groups demonstrated significant improvements in objective measurements in which large treatment effect was achieved (for FEV1 η²=0.218, for 6MWT η²=0.771). Similarly, in subjective measurements a large effect was achieved (for the Beck score: η²=0.599, for the Zung score: η²=0.536). QoL improved after the intervention in all the monitored SF-36 scales in both groups (P<0.001 for all). In patients with COPD, the improvement of exercise capacity was positively correlated with baseline 6MWT and FEV1, and negatively with the Beck anxiety score and the Borg dyspnea score, whereas, only improvement in the mental summary component of QoL was negatively correlated with baseline 6MWT and FEV1 (P<0.05 for all). CONCLUSIONS Rehabilitation in a mountain environment has proven to be effective in both the reported diagnoses of COPD and CB. Improvements in both functional and subjective indicators were observed. These findings support the use of this treatment modality.

Self-management behaviors to reduce exacerbation impact in COPD patients: a Delphi study

BACKGROUND

Little is known about which self-management behaviors have the highest potential to influence exacerbation impact in COPD patients. We aimed to reach expert consensus on the most relevant set of self-management behaviors that can be targeted and influenced to maximize reduction of exacerbation impact.

MATERIALS AND METHODS

A 2-round Delphi study was performed using online surveys to rate the relevance and feasibility of predetermined self-management behaviors identified by literature and expert opinion. Descriptive statistics and qualitative analyses were used.

RESULTS

An international expert panel reached consensus on 17 self-management behaviors focusing on: stable phase (n=5): pharmacotherapy, vaccination, physical activity, avoiding stimuli and smoking cessation; periods of symptom deterioration (n=1): early detection; during an exacerbation (n=5): early detection, health care contact, self-treatment, managing stress/anxiety and physical activity; during recovery (n=4): completing treatment, managing stress/anxiety, physical activity and exercise training; and after recovery (n=2): awareness for recurrent exacerbations and restart of pulmonary rehabilitation.

CONCLUSION

This study has provided insight into expert opinion on the most relevant and feasible self-management behaviors that can be targeted and influenced before, during and after an exacerbation to exert the highest magnitude of influence on the impact of exacerbations. Future research should focus at developing more comprehensive patient-tailored interventions supporting patients in these exacerbation-related self-management behaviors.

Development of a training program to support health care professionals to deliver the SPACE for COPD self-management program

BACKGROUND

With the growing burden of COPD and associated morbidity and mortality, a need for self-management has been identified. The Self-management Programme of Activity, Coping and Education for Chronic Obstructive Pulmonary Disease (SPACE for COPD) manual was developed to support self-management in COPD patients. Currently, there is no literature available regarding health care professionals' training needs when supporting patients with COPD on self-management.

AIM

This study sought to identify these needs to inform, design and develop a training program for health care professionals being trained to deliver a self-management program in COPD.

METHODS

Fourteen health care professionals from both primary and secondary care COPD services participated in face-to-face semistructured interviews. Thematic analysis was used to produce a framework and identify training needs and views on delivery of the SPACE for COPD self-management program. Components of training were web-based knowledge training, with pre-and posttraining knowledge questionnaires, and a 1-day program to introduce the self-management manual. Feedback was given after training to guide the development of the training program.

RESULTS

Health care professionals were able to identify areas where they required increased knowledge to support patients. This was overwhelming in aspects of COPD seen to be outside of their current clinical role. Skills in goal setting and behavioral change were not elicited as a training need, suggesting a lack of understanding of components of supporting self-management. An increase in knowledge of COPD was demonstrated following the training program.

CONCLUSION

Both knowledge and skill gaps existed in those who would deliver self-management. Analysis of this has enabled a training program to be designed to address these gaps and enable health care professionals to support patients in self-management.

COPD: Health Care Utilisation Patterns with Different Disease Management Interventions

PURPOSE

The management of COPD is a significant and costly issue worldwide, with acute healthcare utilisation consisting of admissions and outpatient attendances being a major contributor to the cost. Pulmonary rehabilitation (PR) and integrated disease management (IDM) are often offered. Whilst there is strong evidence of physical and quality of life outcomes following IDM and PR, few studies have looked into healthcare utilisation. The aims of this study were to confirm whether IDM and PR reduce acute healthcare utilisation and to identify factors which contribute to acute health care utilisation or increased mortality.

METHODS

This was a retrospective cohort study of patients with COPD who were referred to IDM over a 10-year period. Patients were also offered an 8-week PR program. Data collected were matched with the hospital dataset to obtain information on inpatient, ED and outpatient attendances.

RESULTS

517 patients were enrolled to IDM. 315 (61%) also commenced PR and 220 (43%) completed PR. Patients who were referred to PR were younger and had less comorbidities (p < 0.001). Both groups (IDM only and IDM + PR referred) had reductions in healthcare utilisation but the IDM-only group had greater reductions. A survival benefit (HR 0.68, 95% CI 0.50-0.92) was seen in those who were PR completers compared to patients who received IDM only.

CONCLUSIONS

Patients with COPD who successfully complete PR in addition to participating in IDM have improved survival. IDM alone was effective in the reduction of healthcare utilisation; however, the addition of PR did not reduce healthcare usage further.

Determinants of activation for self-management in patients with COPD

BACKGROUND

COPD self-management is a complex behavior influenced by many factors. Despite scientific evidence that better disease outcomes can be achieved by enhancing self-management, many COPD patients do not respond to self-management interventions. To move toward more effective self-management interventions, knowledge of characteristics associated with activation for self-management is needed. The purpose of this study was to identify key patient and disease characteristics of activation for self-management.

METHODS

An explorative cross-sectional study was conducted in primary and secondary care in patients with COPD. Data were collected through questionnaires and chart reviews. The main outcome was activation for self-management, measured with the 13-item Patient Activation Measure (PAM). Independent variables were sociodemographic variables, self-reported health status, depression, anxiety, illness perception, social support, disease severity, and comorbidities.

RESULTS

A total of 290 participants (age: 67.2±10.3; forced expiratory volume in 1 second predicted: 63.6±19.2) were eligible for analysis. While poor activation for self-management (PAM-1) was observed in 23% of the participants, only 15% was activated for self-management (PAM-4). Multiple linear regression analysis revealed six explanatory determinants of activation for self-management (P<0.2): anxiety (β: -0.35; -0.6 to -0.1), illness perception (β: -0.2; -0.3 to -0.1), body mass index (BMI) (β: -0.4; -0.7 to -0.2), age (β: -0.1; -0.3 to -0.01), Global Initiative for Chronic Obstructive Lung Disease stage (2 vs 1 β: -3.2; -5.8 to -0.5; 3 vs 1 β: -3.4; -7.1 to 0.3), and comorbidities (β: 0.8; -0.2 to 1.8), explaining 17% of the variance.

CONCLUSION

This study showed that only a minority of COPD patients is activated for self-management. Although only a limited part of the variance could be explained, anxiety, illness perception, BMI, age, disease severity, and comorbidities were identified as key determinants of activation for self-management. This knowledge enables health care professionals to identify patients at risk of inadequate self-management, which is essential to move toward targeting and tailoring of self-management interventions. Future studies are needed to understand the complex causal mechanisms toward change in self-management.

Pulmonary rehabilitation for chronic obstructive pulmonary disease

BACKGROUND

Widespread application of pulmonary rehabilitation (also known as respiratory rehabilitation) in chronic obstructive pulmonary disease (COPD) should be preceded by demonstrable improvements in function (health-related quality of life, functional and maximal exercise capacity) attributable to the programmes. This review updates the review reported in 2006.

OBJECTIVES

To compare the effects of pulmonary rehabilitation versus usual care on health-related quality of life and functional and maximal exercise capacity in persons with COPD.

SEARCH METHODS

We identified additional randomised controlled trials (RCTs) from the Cochrane Airways Group Specialised Register. Searches were current as of March 2014.

SELECTION CRITERIA

We selected RCTs of pulmonary rehabilitation in patients with COPD in which health-related quality of life (HRQoL) and/or functional (FEC) or maximal (MEC) exercise capacity were measured. We defined 'pulmonary rehabilitation' as exercise training for at least four weeks with or without education and/or psychological support. We defined 'usual care' as conventional care in which the control group was not given education or any form of additional intervention. We considered participants in the following situations to be in receipt of usual care: only verbal advice was given without additional education; and medication was altered or optimised to what was considered best practice at the start of the trial for all participants.

DATA COLLECTION AND ANALYSIS

We calculated mean differences (MDs) using a random-effects model. We requested missing data from the authors of the primary study. We used standard methods as recommended by The Cochrane Collaboration.

MAIN RESULTS

Along with the 31 RCTs included in the previous version (2006), we included 34 additional RCTs in this update, resulting in a total of 65 RCTs involving 3822 participants for inclusion in the meta-analysis.We noted no significant demographic differences at baseline between members of the intervention group and those who received usual care. For the pulmonary rehabilitation group, the mean forced expiratory volume at one second (FEV1) was 39.2% predicted, and for the usual care group 36.4%; mean age was 62.4 years and 62.5 years, respectively. The gender mix in both groups was around two males for each female. A total of 41 of the pulmonary rehabilitation programmes were hospital based (inpatient or outpatient), 23 were community based (at community centres or in individual homes) and one study had both a hospital component and a community component. Most programmes were of 12 weeks' or eight weeks' duration with an overall range of four weeks to 52 weeks.The nature of the intervention made it impossible for investigators to blind participants or those delivering the programme. In addition, it was unclear from most early studies whether allocation concealment was undertaken; along with the high attrition rates reported by several studies, this impacted the overall risk of bias.We found statistically significant improvement for all included outcomes. In four important domains of quality of life (QoL) (Chronic Respiratory Questionnaire (CRQ) scores for dyspnoea, fatigue, emotional function and mastery), the effect was larger than the minimal clinically important difference (MCID) of 0.5 units (dyspnoea: MD 0.79, 95% confidence interval (CI) 0.56 to 1.03; N = 1283; studies = 19; moderate-quality evidence; fatigue: MD 0.68, 95% CI 0.45 to 0.92; N = 1291; studies = 19; low-quality evidence; emotional function: MD 0.56, 95% CI 0.34 to 0.78; N = 1291; studies = 19; mastery: MD 0.71, 95% CI 0.47 to 0.95; N = 1212; studies = 19; low-quality evidence). Statistically significant improvements were noted in all domains of the St. George's Respiratory Questionnaire (SGRQ), and improvement in total score was better than 4 units (MD -6.89, 95% CI -9.26 to -4.52; N = 1146; studies = 19; low-quality evidence). Sensitivity analysis using the trials at lower risk of bias yielded a similar estimate of the treatment effect (MD -5.15, 95% CI -7.95 to -2.36; N = 572; studies = 7).Both functional exercise and maximal exercise showed statistically significant improvement. Researchers reported an increase in maximal exercise capacity (mean Wmax (W)) in participants allocated to pulmonary rehabilitation compared with usual care (MD 6.77, 95% CI 1.89 to 11.65; N = 779; studies = 16). The common effect size exceeded the MCID (4 watts) proposed by Puhan 2011(b). In relation to functional exercise capacity, the six-minute walk distance mean treatment effect was greater than the threshold of clinical significance (MD 43.93, 95% CI 32.64 to 55.21; participants = 1879; studies = 38).The subgroup analysis, which compared hospital-based programmes versus community-based programmes, provided evidence of a significant difference in treatment effect between subgroups for all domains of the CRQ, with higher mean values, on average, in the hospital-based pulmonary rehabilitation group than in the community-based group. The SGRQ did not reveal this difference. Subgroup analysis performed to look at the complexity of the pulmonary rehabilitation programme provided no evidence of a significant difference in treatment effect between subgroups that received exercise only and those that received exercise combined with more complex interventions. However, both subgroup analyses could be confounded and should be interpreted with caution.

AUTHORS' CONCLUSIONS

Pulmonary rehabilitation relieves dyspnoea and fatigue, improves emotional function and enhances the sense of control that individuals have over their condition. These improvements are moderately large and clinically significant. Rehabilitation serves as an important component of the management of COPD and is beneficial in improving health-related quality of life and exercise capacity. It is our opinion that additional RCTs comparing pulmonary rehabilitation and conventional care in COPD are not warranted. Future research studies should focus on identifying which components of pulmonary rehabilitation are essential, its ideal length and location, the degree of supervision and intensity of training required and how long treatment effects persist. This endeavour is important in the light of the new subgroup analysis, which showed a difference in treatment effect on the CRQ between hospital-based and community-based programmes but no difference between exercise only and more complex pulmonary rehabilitation programmes.

Are improvements maintained after in-home pulmonary telerehabilitation for patients with chronic obstructive pulmonary disease?

This study investigated if improvements can be maintained over 24 weeks when in-home pulmonary telerehabilitation is combined with asynchronous self-management education for Chronic Obstructive Pulmonary Disease (COPD). Twenty-three community-living elders with moderate to very severe COPD participated in a pre/post-intervention study. Over 8 weeks, they had access to self-learning capsules on self-management, received 15 in-home teletreatment sessions and were encouraged to gradually engage in unsupervised sessions. Participants were assessed before the intervention (T1), immediately after the intervention (T2), and 6 months later (T3). Outcome measures were (1) exercise tolerance (6-minute walk test [6MWT]), Cycle Endurance Test [CET]), and (2) quality of life (Chronic Respiratory Questionnaire [CRQ]). Although there were significant improvements after 8 weeks of pulmonary telerehabilitation on the 6MWT, CET and three of four CRQ domains, none of these improvements were maintained after 6 months and scores returned to their baseline values (all p values > 0.05 when comparing T3 with T1). While pulmonary telerehabilitation is possible and has a positive impact on patients with moderate to very severe COPD, improvements were not maintained in the long-term even when physical therapy was accompanied by self-management education.

Engaging community stakeholders to evaluate the design, usability, and acceptability of a chronic obstructive pulmonary disease social media resource center

Background

Patients with chronic obstructive pulmonary disease (COPD) often report inadequate access to comprehensive patient education resources.

Objective

The purpose of this study was to incorporate community-engagement principles within a mixed-method research design to evaluate the usability and acceptability of a self-tailored social media resource center for medically underserved patients with COPD.

Methods

A multiphase sequential design (qual → QUANT → quant + QUAL) was incorporated into the current study, whereby a small-scale qualitative (qual) study informed the design of a social media website prototype that was tested with patients during a computer-based usability study (QUANT). To identify usability violations and determine whether or not patients found the website prototype acceptable for use, each patient was asked to complete an 18-item website usability and acceptability questionnaire, as well as a retrospective, in-depth, semistructured interview (quant + QUAL).

Results

The majority of medically underserved patients with COPD (n=8, mean 56 years, SD 7) found the social media website prototype to be easy to navigate and relevant to their self-management information needs. Mean responses on the 18-item website usability and acceptability questionnaire were very high on a scale of 1 (strongly disagree) to 5 (strongly agree) (mean 4.72, SD 0.33). However, the majority of patients identified several usability violations related to the prototype’s information design, interactive capabilities, and navigational structure. Specifically, 6 out of 8 (75%) patients struggled to create a log-in account to access the prototype, and 7 out of 8 patients (88%) experienced difficulty posting and replying to comments on an interactive discussion forum.

Conclusions

Patient perceptions of most social media website prototype features (eg, clickable picture-based screenshots of videos, comment tools) were largely positive. Mixed-method stakeholder feedback was used to make design recommendations, categorize usability violations, and prioritize potential solutions for improving the usability of a social media resource center for COPD patient education.

Effect of enhanced psychosocial assessment on readmissions of patients with chronic obstructive pulmonary disease

In 2015, the Patient Protection and Affordable Care Act of 2010 will mandate reduced Medicare reimbursements for hospitals with Chronic Obstructive Pulmonary Disease (COPD) readmissions that are higher than expected. Several studies identified social issues as a concern and possible contributor to readmissions. This study calculated readmission rates for patients with COPD following an enhanced psychosocial assessment. With 26 participants serving as their own historical controls, a paired t-test of the mean of admissions 90 days prior to the assessment and 90 days postassessment was conducted. The study group had a significantly lower number of readmissions in the 90 days postintervention.

Collaborative self-management and behavioral change

Behavioral change is critical for improving health outcomes in patients with chronic obstructive pulmonary disease. An educational approach alone is insufficient; changes in behavior, especially the acquisition of self-care skills, are also required. There is mounting evidence that embedding collaborative self-management (CSM) within existing health care systems provides an effective model to meet these needs. CSM should be integrated with pulmonary rehabilitation programs, one of the main goals of which is to induce long-term changes in behavior. More research is needed to evaluate the effectiveness of assimilating CSM into primary care, patient-centered medical homes, and palliative care teams.

Educational programmes in COPD management interventions: a systematic review

BACKGROUND

According to practice guidelines, educational programmes for patients with COPD should address several educational topics. Which topics are incorporated in the existing programmes remains unclear.

OBJECTIVES

To delineate educational topics integrated in current COPD management interventions; and to examine strengths, weaknesses, and methods of delivery of the educational programmes.

DATA SOURCES

A systematic literature search was performed using MEDLINE/PubMed, Cochrane Central Registry of Controlled Clinical Trials, and Web of Science. The authors of included studies were contacted for additional information.

STUDY SELECTION

Studies that contained educational programmes incorporated in COPD management interventions were included.

DATA EXTRACTION

Data were extracted using a pre-designed data form. The Reach, Efficacy, Adoption, Implementation and Maintenance (RE-AIM) framework was used for evaluating the strengths and weaknesses of the programmes.

DATA SYNTHESIS

In total, 81 articles, describing 67 interventions were included. The majority (53.8%) of the studies incorporated 10 or more educational topics. The following topics were frequently addressed: smoking cessation (80.0%); medication (76.9%); exercise (72.3%); breathing strategies (70.8%); exacerbations (69.2%); and stress management (67.7%). Printed material and/or brochure (90.5%) and demonstrations and practice (73.8%), were the predominant tool and method, respectively. Nurses (75.8%), physicians (37.9%) and physiotherapists (34.8%) were the most involved healthcare professionals.

CONCLUSIONS

Heterogeneity and wide variation in the content and the method of delivery of educational interventions were present. Alignment between educational topics incorporated in the existing programmes and those recommended by the COPD guidelines, involvement of various professionals and combined use of methods should be emphasised.

Distribution of antiretroviral treatment through self-forming groups of patients in Tete Province, Mozambique

BACKGROUND

As antiretroviral treatment cohorts continue to expand, ensuring patient retention over time is an increasingly important concern. This, together with capacity and human resource constraints, has led to the consideration of out-of-clinic models for the delivery of antiretroviral therapy (ART). In 2008, Médecins Sans Frontières and the Provincial authorities launched a model of ART distribution and adherence monitoring by community groups in Tete Province, Mozambique. PROGRAMME APPROACH: Patients who were stable on ART for 6 months were informed about the community ART group model and invited to form groups. Group members had 4 key functions: facilitate monthly ART distribution to other group members in the community, provide adherence and social support, monitor outcomes, and ensure each group member undergoes a clinical consultation at least once every 6 months. Group members visit the health centre on a rotational basis, such that each group member has contact with the health service every 6 months.

RESULTS

Between February 2008 and May 2010, 1384 members were enrolled into 291 groups. Median follow-up time within a group was 12.9 months (IQR 8.5-14.1). During this time, 83 (6%) were transferred out, and of the 1301 patients still in community groups, 1269 (97.5%) were remaining in care, 30 (2%) had died, and 2 (0.2%) were lost to follow-up.

DISCUSSION

The Community ART Group model was initiated by patients to improve access, patient retention, and decongest health services. Early outcomes are highly satisfactory in terms of mortality and retention in care, lending support to such out-of-clinic approaches.

A Critical Review of Effects of COPD Self-Management Education on Self-Efficacy

Chronic obstructive pulmonary disease (COPD) causes progressive airflow limitation which results in prolonged episodes of coughing and shortness of breath. COPD self-management education (COPDSME) programs attempt to enhance patient self-efficacy for managing symptoms. The purpose of this paper was to conduct a critical literature review that identified peer-reviewed articles assessing the effects of COPDSME on self-efficacy outcomes. Seven articles were located after an exhaustive search. Most studies () reported statistically significant improvements in self-efficacy following intervention. Almost all of the studies tested interventions that drew upon at least 2 recommended sources of efficacy information. Two studies specifically noted increased self-efficacy for controlling physical exertion following COPDSME. Within the reviewed studies, the content within each educational treatment varied widely and showed a lack of standardization, and the types of instruments used to assess self-efficacy varied. This paper highlights the need for more controlled trials that investigate potential between-subjects effects of different types of COPDSME programs on self-efficacy outcomes. Incorporating practice models for patient-centered primary care in COPD requires the use of tailored efficacy building strategies for specific self-management behaviors.

Patient knowledge in chronic obstructive pulmonary disease: back to basics

Patient education is integral to the care of patients with chronic obstructive pulmonary disease (COPD), and a cornerstone of self-management in chronic illness. We aimed to assess information needs and knowledge of patients with COPD. The Lung Information Needs Questionnaire (LINQ) and The Mount Sinai Hospital Questionnaire (MSHQ) were used. The LINQ identifies what COPD information the patient has, or is lacking. Higher scores in the LINQ define a greater information need. The MSHQ assesses a patients' COPD knowledge. Higher scores in the MSHQ questionnaire indicate greater knowledge. Subjects, in (n = 38) and outpatients (n = 43) were aged (mean ± SD) 69 ± 9 years, 53% were women, and 36% had not completed high school. COPD was diagnosed 9 ± 7 years previously. Forty percent had recalled receiving specific COPD education. Mean forced expiratory volume in 1 second (FEV1) was 1.1 ± 0.6 Liters. Patients on average had a 29 ± 14% need for information as assessed by the LINQ. Patients indicated a 52 ± 34% need for information on diet and 43 ± 25% for self-management. The mean total score for the MSHQ was 71 ± 13%. The score on treatment was 76 ± 20% and 60 ± 14% on pathophysiology. There was a positive relationship between having prior COPD education, finishing high school and total MSHQ score (p < 0.05) and a positive correlation of prior COPD education and reduced LINQ total score (p < 0.01). Patients with COPD have received information and demonstrate some knowledge about their disease. However, there remains a need for more education on diet and self-management.

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.

Living in a rural area with advanced chronic respiratory illness: a qualitative study

AIM

To explore the impact of living with advanced chronic respiratory illness in a rural area

METHODS

Using an interpretive descriptive approach, semi-structured interviews were conducted with seven people living with advanced chronic respiratory illness in a rural area of Western Canada.

RESULTS

Themes that characterised the experience of living in a rural setting with a chronic obstructive respiratory illness included: a) distance as a barrier to accessing health care; b) relationships with family practice physicians; c) supportive local community; and d) lack of respiratory education and peer support.

CONCLUSIONS

Whilst living with advanced respiratory illness in a rural area posed some significant challenges, experiences of "place", conceptualised as a web of relationships embedded within a local context, are an important factor in rural residents' decisions to remain in situations where distance may present significant challenges to accessing health care.

Using Exploratory Focus Groups to Inform the Development of Targeted COPD Self-Management Education DVDs for Rural Patients

This exploratory study assessed the self-management learning needs, experiences, and perspectives of COPD patients treated at a Certified Federal Rural Health Clinic to inform the development of a COPD self-management DVD. A purposive, homogeneous sample of COPD patients participated in focus group interviews. Data from these interviews were referenced to edit a library of Rvision COPD self-management DVDs into a single condensed DVD containing only the most pertinent self-management topics. Patients reported a lack of knowledge and skill development related to purse lipped breathing, controlled coughing, and stress management; while medication management skills were found to be quite adequate. Engaging rural communities in formal qualitative inquiries to describe COPD specific needs for self-management may lead to future use of educational technologies aimed at improving quality of life for these rural, hard to reach populations.

Patient-clinician communication: associations with important health outcomes among veterans with COPD

BACKGROUND

High quality patient-clinician communication is widely advocated, but little is known about which health outcomes are associated with communication for patients with COPD.

METHODS

Using a cross-sectional study of 342 veterans enrolled in a randomized controlled trial, we evaluated the association of communication, measured with the quality of communication (QOC) instrument, with subject-reported quality of clinician care, breathing problem confidence, and general self-rated health. We measured these associations using general estimating equations and adjusted odds ratios (OR) of patient-reported outcomes associated with one-point changes in QOC scores.

RESULTS

Nearly one-half of the subjects reported receiving the best imaginable care (47%), whereas fewer reported being confident with their breathing problems all the time (29%) or in very good or excellent health (15%). General communication was associated with best-imagined quality of care (OR, 4.29; 95% CI, 2.84-6.48; P < .001) and confidence in dealing with breathing problems all the time (OR, 1.74; 95% CI, 1.34-2.25; P < .001) but not general self-rated health (OR, 1.19; 95% CI, 0.92-1.55; P = .19). Specific clinician behaviors with larger associations with higher quality care included listening, caring, and attentiveness. The associations between general communication and quality care increased over time (P for interaction .03).

CONCLUSIONS

Communication between patients and clinicians is associated with quality of care and confidence in dealing with breathing problems, and this association may change over time. Attention to specific communication strategies may lead to improvements in the care of patients with COPD.

Living with chronic obstructive pulmonary disease: a survey of patients' knowledge and attitudes

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) is a common respiratory condition and the fourth leading cause of death in Canada. However, little is known about the impact of COPD on the lives and attitudes of individuals living with this condition. The purpose of this study was to determine whether Canadians with COPD are properly educated and supported, and to recommend solutions to any care gaps identified.

METHODS

A total of 389 Canadians were surveyed who were 40 years of age and older, physician diagnosed with COPD, and current or former smokers. The telephone survey contained 68 items and took 35 min to complete. COPD severity was classified according to symptom severity using the Medical Research Council (MRC) score.

RESULTS

Respondents tended to overestimate their disease severity and reported substantial symptom burden and psychosocial impact of living with COPD. Most individuals claimed to be well informed about COPD; however, their knowledge was poor in several domains including the causes of COPD, the consequences of inadequate therapy and the management of exacerbations. Family physicians were the main health care providers. A minority of respondents had seen a lung health educator. Only 34% had ever received a written action plan and only 33% had been told how to prevent an exacerbation.

CONCLUSIONS

The symptom burden and psychosocial impact of living with COPD is substantial. There are significant gaps in patients' knowledge about the management of COPD and little contact with lung health educators. Increased use of COPD-specific, self-management education programs may help rectify these care gaps.

Acute exacerbation of chronic obstructive pulmonary disease: influence of social factors in determining length of hospital stay and readmission rates

BACKGROUND

Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is the leading reason for hospitalization in Canada and a significant financial burden on hospital resources. Identifying factors that influence the time a patient spends in the hospital and readmission rates will allow for better use of scarce hospital resources.

OBJECTIVES

To determine the factors that influence length of stay (LOS) in the hospital and readmission for patients with AECOPD in an inner-city hospital.

METHODS

Using the Providence Health Records, a retrospective review of patients admitted to St Paul's Hospital (Vancouver, British Columbia) during the winter of 2006 to 2007 (six months) with a diagnosis of AECOPD, was conducted. Exacerbations were classified according to Anthonisen criteria to determine the severity of exacerbation on admission. Severity of COPD was scored using the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. For comparative analysis, severity of disease (GOLD criteria), age, sex and smoking history were matched.

RESULTS

Of 109 admissions reviewed, 66 were single admissions (61%) and 43 were readmissions (39%). The number of readmissions ranged from two to nine (mean of 3.3 readmissions). More than 85% of admissions had the severity of COPD equal to or greater than GOLD stage 3. The significant indicators for readmission were GOLD status (P<0.001), number of related comorbidities (OR 1.47, 95% CI 1.10 to 1.97; P<0.009) and marital status (single) (OR 4.18, 95% CI 1.03 to 17.02; P<0.046). The requirement for social work involvement during hospital admission was associated with a prolonged LOS (P<0.05).

CONCLUSIONS

The results of the present study show that disease severity (GOLD status) and number of comorbidities are associated with readmission rates of patients with AECOPD. Interestingly, social factors such as marital status and the need for social work intervention are also linked to readmission rates and LOS, respectively, in patients with AECOPD.
