Integrated disease management interventions for patients with chronic obstructive pulmonary disease

Cluster randomised controlled trial of specialist-led integrated COPD care (INTEGR COPD)

OBJECTIVE

Studies in hospital settings demonstrate that there is greater guideline adherence when care is delivered by a respiratory specialist, however, this has not been explored in primary care. The aim of this study is to determine the impact integrating respiratory specialists into primary care has on the delivery of guideline adherent chronic obstructive pulmonary disease (COPD) care.

METHODS

18 general practitioner (GP) practices were randomised to provide either usual or specialist-led COPD care. Patients at participating practices were included if they had an existing diagnosis of COPD. Outcomes were measured at the individual patient level. The primary outcome was guideline adherence, assessed as achieving four or more items of the COPD care bundle. Secondary outcome measures included quality of life, number of exacerbations, number of COPD-related hospitalisations and respiratory outpatient attendances.

RESULTS

586 patients from 10 practices randomised to the intervention and 656 patients from 8 practices randomised to the control arm of the study were included. The integration of respiratory specialists into GP practices led to a statistically significant (p<0.001) improvement in the provision of guideline adherent care when compared with usual care in this cohort (92.7% vs 70.1%) (OR 4.14, 95% CI 2.14 to 8.03).

CONCLUSION

This is the first study to demonstrate that guideline adherence is improved through the integration of respiratory specialists into GP practices to deliver annual COPD reviews. To facilitate changes in current healthcare practice and policy, the findings of this paper need to be viewed in combination with qualitative research exploring the acceptability of specialist integration.

Addressing Barriers to Chronic Obstructive Pulmonary Disease (COPD) Care: Three Innovative Evidence-Based Approaches: A Review

Chronic obstructive pulmonary disease (COPD) is a preventable yet widespread and profoundly debilitating respiratory condition, exerting substantial personal and global health ramifications alongside significant economic implications. The first objective of this literature review was to identify reviews the barriers to optimal COPD care, categorizing them into personal patient factors, professional awareness and knowledge, patient-professional relationships, and healthcare service models, including access to care that significantly impacts the quality of COPD management. The second objective was to introduce three approaches for enhancing COPD care outcomes: Self-Management Educational Programs, Health Qigong, and Telehealth service provision, each demonstrating positive effects on COPD patients' health status. These evidence-based interventions offer promising avenues for enhancing COPD care and patient outcomes. Integrating these approaches into comprehensive COPD management strategies holds potential for improving the well-being and quality of life of individuals living with this chronic condition.

[Interventions to reduce hospital readmission rates in patients with COPD: a systematic review]

BACKGROUND

Patients with chronic obstructive pulmonary disease (COPD) have a high risk of hospital and intensive care unit readmission. Readmissions are a severe burden on patients, families, and the health care system. The aim of this study is to identify pedagogical-counseling interventions to reduce readmissions and other parameters in COPD patients.

METHODS

A systematic literature search was performed in March 2022 in the databases Medline, Cochrane Library, CINAHL, and LIVIVO. German‑, English‑, Arabic-, and French-language (cluster-) randomized, controlled studies were included.

RESULTS

In all, 21 studies with a total of 3894 COPD patients were included. The quality of included studies was moderate to good. Interventions were self-management programs, telemedical, and educational interventions. Five out of seven studies found a significant reduction in readmissions for self-management programs (p = 0.02-0.49). A positive effect of telemedicine interventions on outcome parameters was only reported in two studies (p < 0.05) and no significant effect in four studies. Educational interventions were examined in six studies: four found no difference between the study groups and two found a significant difference in favor of the intervention group (p = 0.01). Special care programs also showed a significant effect in two studies.

CONCLUSION

Estimating the Health and Economic Impact of Improved Management in Prevalent Chronic Obstructive Pulmonary Disease Populations in England, Germany, Canada, and Japan: A Modelling Study

Introduction

COPD is a leading cause of morbidity and mortality globally. Management is complex and costly. Although international quality standards for diagnosis and management exist, opportunities remain to improve outcomes, especially in reducing avoidable hospitalisations.

Objective

To estimate the potential health and economic impact of improved adherence to guideline-recommended care for prevalent, on-treatment COPD populations in four high-income settings.

Methods

A disease simulation model was developed to evaluate the impact of theoretical improvements to COPD management, comparing outcomes for usual care and policy scenarios for interventions that reduce avoidable hospitalisations: 1) increased attendance (50% vs 31-38%) of early follow-up review after severe exacerbation hospitalisation; 2) increased access (30% vs 5-10%) to an integrated disease management (IDM) programme that provides guideline adherent care.

Results

For cohorts of 100,000 patients, Policy 1 yielded additional life years (England: 523; Germany: 759; Canada: 1316; Japan: 512) and lifetime cost savings (-£2.89 million; -€6.58 million; -$40.08 million; -¥735.58 million). For Policy 2, additional life years (2299; 3619; 3656) and higher lifetime total costs (£38.15 million; €35.58 million; ¥1091.53 million) were estimated in England, Germany and Japan, and additional life years (4299) and cost savings (-$20.52 million) in Canada. Scenarios found that the cost impact depended on the modelled intervention effect size.

Conclusion

Interventions that reduce avoidable hospitalisations are estimated to improve survival and may generate cost savings. This study provides evidence on the theoretical impact of policies to improve COPD care and highlights priority areas for further research to support evidence-based policy decisions.

Clinical Management of COPD in the Real World: Can Studies Reveal Errors in Management and Pathways to Improve Patient Care?

Real world data comprise information on health care that is derived from multiple sources outside typical clinical research settings. This review focuses on what real world evidence tells us about problems with the diagnosis of chronic obstructive pulmonary disease (COPD), problems with the initial and follow-up pharmacological and non-pharmacological management, problems with the management of exacerbations and problems with palliative care. Data from real world studies show errors in the management of COPD with delays to diagnosis, lack of confirmation of the diagnosis with spirometry, lack of holistic assessment, lack of attention to smoking cessation, variable adherence to management guidelines, delayed implementation of appropriate interventions, under-recognition of patients at higher risk of adverse outcomes, high hospitalisation rates for exacerbations and poor implementation of palliative care. Understanding that these problems exist and considering how and why they occur is fundamental to developing solutions to improve the diagnosis and management of patients with COPD.

Acceptability, Appropriateness and Feasibility of a Nurse-Led Integrated Care Intervention for Patients with Severe Exacerbation of COPD from the Healthcare Professional's Perspective - A Mixed Method Study

Purpose

To improve inpatient care and self-management in patients with severe acute exacerbations of COPD, we implemented a nurse-led behavioral intervention. This study aimed to assess implementation outcomes from the perspective of the healthcare professionals (HCP) who delivered it.

Methods

Using an explanatory sequential mixed method approach, we conducted an online questionnaire and two small group interviews. We applied descriptive statistics for quantitative data, a framework analysis for qualitative data, and a mixed methods matrix to integrate the results.

Results

A total of 19 of 27 invited participants answered the online questionnaire; 9 of 19 participated in the group interviews. The intervention's overall acceptability, appropriateness, and feasibility was rated high to very high (median 5/5; 4/5 and 4/5). Enablers to implementation included general recognition of the need for specialized care, sufficient knowledge of the intervention by HCP, and strong interprofessional collaboration. Main barriers included the lack of resident physician's resources and difficulties in adaptability.

Conclusion

While the acceptance of the intervention was very high, the perceived appropriateness and feasibility were affected by its complexity. The availability of a knowledgeable interprofessional core team is a strategy that supports the implementation of complex interventions.

Enhancing potential impact of hospital discharge interventions for patients with COPD: a qualitative systematic review

BACKGROUND

Patients with chronic obstructive pulmonary disease (COPD) are frequently readmitted to hospital resulting in avoidable healthcare costs. Many different interventions designed to reduce hospital readmissions are reported with limited evidence for effectiveness. Greater insight into how interventions could be better designed to improve patient outcomes has been recommended.

AIM

To identify areas for optimisation within previously reported interventions provided to reduce COPD rehospitalisation to improve future intervention development.

METHODS

A systematic review was conducted by searching Medline, Embase, CINAHL, PsycINFO, and CENTRAL in June 2022. Inclusion criteria were interventions provided to patients with COPD in the transition from hospital to home or community. Exclusion criteria were lack of empirical qualitative results, reviews, drug trials, and protocols. Study quality was assessed using the Critical Appraisal Skills Programme tool and results were synthesised thematically.

RESULTS

A total of 2,962 studies were screened and nine studies included. Patients with COPD experience difficulties when transitioning from hospital to home. It is therefore important for interventions to facilitate a smooth transition process and give appropriate follow-up post-discharge. Additionally, interventions should be tailored for each patient, especially regarding information provided.

CONCLUSION

Very few studies specifically consider processes underpinning COPD discharge intervention implementation. There is a need to recognise that the transition itself creates problems, which require addressing, before introducing any new intervention. Patients report a preference for interventions to be individually adapted-in particular the provision of patient information. Whilst many intervention aspects were well received, feasibility testing may have enhanced acceptability. Patient and public involvement may address many of these concerns and greater use of process evaluations should enable researchers to learn from each other's experiences.

The Influence of Provider Connectedness on Continuity of Care and Hospital Readmissions in Patients With COPD: A Claims Data Based Social Network Study

Background

Hospital readmission rates are very high in patients with chronic obstructive pulmonary disease (COPD). Continuity of care (CoC) with general practitioners (GPs) and ambulatory specialists can impact readmission rates. This study aimed to identify shared patient networks of ambulatory care physicians and to examine the effect of provider connectedness on CoC and hospital readmissions.

Methods

A retrospective observational study was conducted in claims data from the years 2016 to 2018 in patients with COPD (aged 40 years or older; hospital stay in 2017). Linkages between GPs, pneumologists, and cardiologists were determined on the basis of shared patients. Multilevel regression models were used to analyze the impact of provider connectedness, operationalized by several social network characteristics, on continuity of care (sequential continuity [SECON] index) and hospital readmission rates.

Results

A total of 7294 patients linked to 3673 GPs were available for analysis. Closeness centrality (β=- 0.029) and the external-internal (EI)-index (β =0.037) impacted on the SECON index. The EI-index (odds ratio [OR]=1.25) and degree centrality (OR=1.257) impacted 30-day readmission. Network density (OR=0.811) and the SECON index (OR=1.121) affected the likelihood of a 90-day readmission. None of the predictors had a significant impact on 180-day and 365-day readmissions.

Conclusions

Ambulatory care providers' connectedness showed some effects on hospital readmissions and CoC in patients with COPD up to 90 days after hospital discharge, but the additional predictive power is limited.

Supporting Behavior Change After AECOPD - Development of a Hospital-Initiated Intervention Using the Behavior Change Wheel

After hospitalization due to acute COPD exacerbations, patient-manageable behaviors influence rehospitalization frequency. This study's aim was to develop a hospital-ward-initiated Behaviour-Change-Wheel (BCW)-based intervention targeting patients' key health behaviors, with the aim to increase quality of life and reduce rehospitalization frequency. Intervention development was performed by University Hospital Zurich working groups and followed the three BCW stages for each of the three key literature-identified problems: insufficient exacerbation management, lack of physical activity and ongoing smoking. In stage one, by analyzing published evidence - including but not limited to patients' perspective - and health professionals' perspectives regarding these problems, we identified six target behaviors. In stage two, we identified six corresponding intervention functions. As our policy category, we chose developing guidelines and service provision. For stage three, we defined eighteen basic intervention packages using 46 Behaviour Change Techniques in our basic intervention. The delivery modes will be face-to-face and telephone contact. In the inpatient setting, this behavioral intervention will be delivered by a multi-professional team. For at least 3 months following discharge, an advanced nursing practice team will continue and coordinate the necessary care package via telephone. The intervention is embedded in a broader self-management intervention complemented by integrated care components. The BCW is a promising foundation upon which to develop our COPD intervention. In future, the interaction between the therapeutic care team-patient relationships and the delivery of the behavioral intervention will also be evaluated.

Qualitative Validation of COPD Evidenced Care Pathways in Japan, Canada, England, and Germany: Common Barriers to Optimal COPD Care

Background

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. A comprehensive and detailed understanding of COPD care pathways from pre-diagnosis to acute care is required to understand the common barriers to optimal COPD care across diverse health systems.

Methods

Country-specific COPD care pathways were created for four high-income countries using international recommendations and country-specific guidelines, then populated with published epidemiological, clinical, and economic data. To refine and validate the pathways, semi-structured interviews using pre-prepared discussion guides and country-specific pathway maps were held with twenty-four primary and secondary care respiratory healthcare professionals. Thematic analysis was then performed on the interview transcripts.

Results

The COPD care pathway showed broad consistency across the countries. Three key themes relating to barriers in optimal COPD management were identified across the countries: journey to diagnosis, treatment, and the impact of COVID-19. Common barriers included presentation to healthcare with advanced COPD, low COPD consideration, and sub-optimal acute and chronic disease management. COVID-19 has negatively impacted disease management across the pathway but presents opportunities to retain virtual consultations. Structural factors such as insurance and short duration of appointments also impacted the diagnosis and management of COPD.

Conclusion

COPD is an important public health issue that needs urgent prioritization. The use of Evidenced Care Pathways with decision-makers can facilitate evidence-based decision making on interventions and policies to improve care and outcomes for patients and reduce unnecessary resource use and associated costs for the healthcare provider/payer.

Educational interventions for health professionals managing chronic obstructive pulmonary disease in primary care

BACKGROUND

Chronic obstructive pulmonary disease (COPD) is a common, preventable and treatable health condition. COPD is associated with substantial burden on morbidity, mortality and healthcare resources.

OBJECTIVES

To review existing evidence for educational interventions delivered to health professionals managing COPD in the primary care setting.

SEARCH METHODS

We searched the Cochrane Airways Trials Register from inception to May 2021. The Register includes records from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Allied and Complementary Medicine Database (AMED) and PsycINFO. We also searched online trial registries and reference lists of included studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and cluster-RCTs. Eligible studies tested educational interventions aimed at any health professionals involved in the management of COPD in primary care. Educational interventions were defined as interventions aimed at upskilling, improving or refreshing existing knowledge of health professionals in the diagnosis and management of COPD.

DATA COLLECTION AND ANALYSIS

Two review authors independently reviewed abstracts and full texts of eligible studies, extracted data and assessed the risk of bias of included studies. We conducted meta-analyses where possible and used random-effects models to yield summary estimates of effect (mean differences (MDs) with 95% confidence intervals (CIs)). We performed narrative synthesis when meta-analysis was not possible. We assessed the overall certainty of evidence for each outcome using Grades of Recommendation, Assessment, Development and Evaluation (GRADE). Primary outcomes were: 1) proportion of COPD diagnoses confirmed with spirometry; 2) proportion of patients with COPD referred to, participating in or completing pulmonary rehabilitation; and 3) proportion of patients with COPD prescribed respiratory medication consistent with guideline recommendations.

MAIN RESULTS

We identified 38 studies(22 cluster-RCTs and 16 RCTs) involving 4936 health professionals (reported in 19/38 studies) and 71,085 patient participants (reported in 25/38 studies). Thirty-six included studies evaluated interventions versus usual care; seven studies also reported a comparison between two or more interventions as part of a three- to five-arm RCT design. A range of simple to complex interventions were used across the studies, with common intervention features including education provided to health professionals via training sessions, workshops or online modules (31 studies), provision of practice support tools, tool kits and/or algorithms (10 studies), provision of guidelines (nine studies) and training on spirometry (five studies). Health professionals targeted by the interventions were most commonly general practitioners alone (20 studies) or in combination with nurses or allied health professionals (eight studies), and the majority of studies were conducted in general practice clinics. We identified performance bias as high risk for 33 studies. We also noted risk of selection, detection, attrition and reporting biases, although to a varying extent across studies. The evidence of efficacy was equivocal for all the three primary endpoints evaluated: 1) proportion of COPD diagnoses confirmed with spirometry (of the four studies that reported this outcome, two supported the intervention); 2) proportion of patients with COPD who are referred to, participate in or complete pulmonary rehabilitation (of the four studies that reported this outcome, two supported the intervention); and 3) proportion of patients with COPD prescribed respiratory medications consistent with guideline recommendations (12 studies reported this outcome, the majority evaluated multiple drug classes and reported a mixed effect). Additionally, the low quality of evidence and potential risk of bias make the interpretation more difficult. Moderate-quality evidence (downgraded due to risk of bias concerns) suggests that educational interventions for health professionals probably improve the proportion of patients with COPD vaccinated against influenza (three studies) and probably have little impact on the proportion of patients vaccinated against pneumococcal infection (two studies). Low-quality evidence suggests that educational interventions for health professionals may have little or no impact on the frequency of COPD exacerbations (10 studies). There was a high degree of heterogeneity in the reporting of health-related quality of life (HRQoL). Low-quality evidence suggests that educational interventions for health professionals may have little or no impact on HRQoL overall, and when using the COPD-specific HRQoL instrument, the St George's Respiratory Questionnaire (at six months MD 0.87, 95% CI -2.51 to 4.26; 2 studies, 406 participants, and at 12 months MD -0.43, 95% CI -1.52 to 0.67, 4 studies, 1646 participants; reduction in score indicates better health). Moderate-quality evidence suggests that educational interventions for health professionals may improve patient satisfaction with care (one study). We identified no studies that reported adverse outcomes.

AUTHORS' CONCLUSIONS

The evidence of efficacy was equivocal for educational interventions for health professionals in primary care on the proportion of COPD diagnoses confirmed with spirometry, the proportion of patients with COPD who participate in pulmonary rehabilitation, and the proportion of patients prescribed guideline-recommended COPD respiratory medications. Educational interventions for health professionals may improve influenza vaccination rates among patients with COPD and patient satisfaction with care. The quality of evidence for most outcomes was low or very low due to heterogeneity and methodological limitations of the studies included in the review, which means that there is uncertainty about the benefits of any currently published educational interventions for healthcare professionals to improve COPD management in primary care. Further well-designed RCTs are needed to investigate the effects of educational interventions delivered to health professionals managing COPD in the primary care setting.

The Current and Future Role of Technology in Respiratory Care

Over the past few decades, technology and improvements in artificial intelligence have dramatically changed major sectors of our day-to-day lives, including the field of healthcare. E-health includes a wide range of subdomains, such as wearables, smart-inhalers, portable electronic spirometers, digital stethoscopes, and clinical decision support systems. E-health has been consistently shown to enhance the quality of care, improve adherence to therapy, and allow early detection of worsening in chronic pulmonary diseases. The present review addresses the current and potential future role of major e-health tools and approaches in respiratory medicine, with the aim of providing readers with trustful and updated evidence to increase their awareness of the topic, and to allow them to optimally benefit from the latest innovation technology. Collected literature evidence shows that the potential of technology tools in respiratory medicine mainly relies on three fundamental interactions: between clinicians, between clinician and patient, and between patient and health technology. However, it would be desirable to establish widely agreed and adopted standards for conducting trials and reporting results in this area, as well as to take into proper consideration potentially relevant pitfalls related to privacy protection and compliance with regulatory procedures.

The Effects of an Acceptance and Commitment-Informed Interdisciplinary Rehabilitation Program for Chronic Airway Diseases on Health Status and Psychological Symptoms

BACKGROUND

Chronic airway diseases are prevalent and costly conditions. Interdisciplinary rehabilitation programs that include Acceptance and Commitment-based (ACT) components could be important to tackle the vicious circle linking progression of the disease, inactivity, and psychopathological symptoms.

METHODS

A retrospective evaluation of routinely collected data of an interdisciplinary rehabilitation program was performed. The program included group sessions including patient education, breathing exercise, occupational therapy and an ACT-based psychological treatment, and individual sessions of physical therapy. Demographic data, clinical characteristics of the patients and the values of outcome variables (health status, quality of life, anxiety, and depression) before treatment, at discharge, at 3 months, and at 6 months were extracted from medical records. Multiple imputation was employed to address missing data. Linear mixed models were employed to assess changes over time. Multivariable logistic regression was performed to assess predictors of a minimum clinically important change of health status from baseline to the 6-months follow-up.

RESULTS

Data from 31 patients with chronic obstructive pulmonary disease (COPD) and 12 patients with bronchiectasis were extracted. Health status improved from baseline to discharge to the 3 months follow-up, but not to the 6 months follow-up. Anxiety and depression improved across all the time points. Quality of life did not improve over time. Having a worse health status at baseline and fewer depressive symptoms were significantly associated with achieving a minimum clinically important change of health status at 6 months. The effects of the interdisciplinary program were not different for patients with COPD or with bronchiectasis.

DISCUSSION

Interdisciplinary programs including ACT-based components are promising treatments for the rehabilitation of patients with chronic airway diseases.
