The COPDnet integrated care model

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.

Exploration of understanding of integrated care from a public health perspective: A scoping review

Background

Many health care systems attempt to develop an integrated care approach that is a whole population health-oriented system. However, knowledge of strategies to support this effort are scarce and fragmented. The aim of the current paper is to investigate existing concepts of integrated care and their elements from a public health perspective and to propose an elaborated approach that could be applied to explore the public health orientation of integrated care.

Design and methods

We applied a scoping review approach. A literature search was conducted in Embase, Medline, CINAHL, Scopus and Web of Science for the period 2000-2020 yielding 16 studies for inclusion.

Results

Across the papers, 14 frameworks were identified. Nine of these referred to the Chronic Care Model (CCM). Service delivery, person-centeredness, IT systems design and utilization and decision support were identified as the core elements of most of the included frameworks. The descriptions of these elements were mainly clinical-oriented focusing particularly on clinical care processes and treatment of diseases instead of wider determinants of population health.

Conclusions

A synthesized model is proposed that emphasizes the importance of mapping the unique needs and characteristics of the population it aims to serve, leans on the social determinants approach with a commitment to individual and community empowerment, health literacy and suggests reorienting services to meet the expressed needs of the population.

Patient activation is a treatable trait in patients with chronic airway diseases: An observational study

Background

Self-management is key for reducing the burden of disease in chronical illness. However, applying self-management presupposes behavioral change. Sufficient knowledge, skills, confidence and motivation to make the needed behavior changes are important prerequisites. During the past years the Integral Diagnostic Trajectory was developed for patients with asthma or COPD which aims to identify treatable traits and activating patients for self-management.

Objective

In the present study the effects of the Integral Diagnostic Trajectory on the Patient Activation Measure (PAM®) were examined. In addition, predictive variables for PAM baseline scores and change scores were sought.

Materials and methods

A total of 241 patients with asthma or COPD referred to the pulmonologist at the Radboud university medical center, location Dekkerswald, Nijmegen were included. Patient activation was measured before the first visit and after the intervention with the 13-item PAM®. Additional, patient characteristics and health status were measured with the Nijmegen Clinical Screening Instrument (NCSI), modified Medical Research Council (mMRC), Asthma Control Questionnaire (ACQ), and COPD Clinical Questionnaire (CCQ).

Results

Fifty percent of the patients with asthma and seventy percent of the patients with COPD had low levels of activation at baseline (PAM level 1-2). Baseline PAM scores could be explained in patients with asthma for 7% by number of severe problems in health status. And for 18% in patients with COPD by number of severe problems, age and employment status. After the intervention both groups significantly improved on the PAM (T0: 56.0 ± 13.1 vs. T1:63.3 ± 14.0 in asthma, and T0: 50.0 ± 8.8 vs. 58.4 ± 11.1 in COPD). Multivariate stepwise regression analysis showed that only 24% of the change in score could be explained by baseline PAM score and being employed in patients with asthma, and 18% of the variance in change score could be predicted by baseline PAM score in COPD.

Conclusion

The present study showed that low level of activation is a common feature in patients with asthma and COPD. With a relatively short and seemingly simple intervention patients can reach higher levels of patient activation, which is a prerequisite for adopting self-management techniques in daily life.

"Can Do, Do Do" Quadrants and 6-Year All-Cause Mortality in Patients With COPD

BACKGROUND

Physical capacity (PC; "can do") and physical activity (PA; "do do") are prognostic indicators in COPD and can be used to subdivide patients with COPD into four exclusive subgroups (the so-called "can do, do do" quadrants). This concept may be useful to understand better the impact of PC and PA on all-cause mortality in patients with COPD.

RESEARCH QUESTION

What is the 6-year all-cause mortality risk of the "can do, do do" quadrants of patients with COPD?

STUDY DESIGN AND METHODS

This retrospective study used data from patients with COPD who underwent a comprehensive assessment at their first-ever outpatient consultation. PC was assessed using the 6-min walk distance and physical activity was assessed using an accelerometer (steps per day). All-cause mortality data were obtained from the Municipal Personal Records Database. Receiver operating characteristic curves were used to determine threshold values for PC and PA to predict 6-year all-cause mortality. Using the derived threshold values, male and female patients were divided into the four "can do, do do" quadrants.

RESULTS

Data from 829 patients were used for analyses. Best discriminatory values for 6-year mortality were 404 m and 4,125 steps/day for men and 394 m and 4,005 steps/day for women. During a median follow-up of 55 months (interquartile range, 37-71 months), 129 patients (15.6%) died. After controlling for established prognostic factors, patients in the "can do, don't do" quadrant and "can do, do do" quadrant showed significantly lower mortality risk compared with patients in the "can't do, don't do" quadrant: hazard ratios of 0.36 (95% CI, 0.14-0.93) and 0.24 (95% CI, 0.09-0.61) for men and 0.37 (95% CI, 0.38-0.99) and 0.29 (95% CI, 0.10-0.87) for women, respectively. No significant differences were found between the "can't do, do do" and "can't do, don't do" quadrants.

INTERPRETATION

Patients with COPD with a preserved PC seem to have a significantly lower 6-year mortality risk compared with patients with a decreased PC, regardless of physical activity level.

Exploring community members' perceptions to adopt a Tele-COPD program in rural counties

Background

Patients diagnosed with COPD residing in rural areas report a lower quality of life. Telehealth addresses geographic barriers by offering routine, technology-based visits, and remote patient monitoring.

Objective

The study objective was to explore adoption perceptions of a tele-COPD program among community members in rural Western North Carolina (WNC) counties.

Methods

A convenience sample of 17 community members were recruited to participate in one of five 45-min focus groups. Before the focus group, all participants completed a brief demographic survey. Focus groups were digitally recorded, transcribed verbatim, imported into MAXQDA v10, and analyzed thematically using established qualitative coding procedures. SPSS v22 was used to calculate descriptive statistics.

Results

Participants were primarily Non-Hispanic White (100%), male (59%), insured (100%), and had at least a high school education (80%). Only 25% of participants had any prior knowledge of telehealth programs. The majority (94%) of participants expressed interest in receiving a tele-COPD program due to convenience factors. Yet, most participants expressed a lack of interest and comfort in using Internet-capable devices (e.g., mobile devices, tablets, computers). Participants noted that to be successful, telehealth visits must be described and shown to them by their own provider or other trusted individual(s), such as a pharmacist. Privacy and cost were also expressed as telehealth concerns.

Conclusion

Interest in a tele-COPD program was high among community residents in rural WNC. However, to increase patient willingness to adopt a tele-COPD program, patients' providers must overcome challenges, such as patients' awareness and knowledge of telehealth, privacy and cost concerns, and access to and comfort with using new technologies. Pharmacists may mitigate these challenges by increasing patients' trust and comfort with telehealth programs.

•

Telehealth offers video-based visits and remote patient monitoring in rural areas.

Challenges and Strategies for Improving COPD Primary Care Services in Quebec: Results of the Experience of the COMPAS+ Quality Improvement Collaborative

Introduction

Management of chronic obstructive pulmonary disease (COPD) remains a challenge in primary care and multiple barriers can limit implementation of COPD guidelines. Since 2016, a quality improvement (QI) collaborative, called COMPAS+, has been implemented across the province of Quebec (Canada) to support improvement of chronic disease management in primary care. The aim of this study was to describe the main COPD quality problems reported by participating teams and the strategies they proposed and implemented to improve COPD primary care services in Quebec.

Methods

Sixteen sites in four different regions of Quebec were engaged in the COMPAS+ intervention to improve primary care services delivered to people living with COPD. A total of 14 workshop reports, 31 QI action plans and 4 regional final reports underwent content analysis. Key COPD quality problems were first identified and, for each of them, root causes were classified according to the domains and constructs of the Consolidated Framework for Implementation Research. Proposed strategies were organized according to the intervention function types described in the Behavior Change Wheel.

Results

Four key COPD quality problems were identified: 1) lack of organization/coordination of COPD services, 2) lack of screening services coordination, 3) lack of interprofessional communication and collaboration and 4) lack of treatment adherence. Main root causes explaining these quality gaps were 1) lack of awareness of COPD, 2) lack of professional knowledge, 3) lack of definition of professional roles, 4) lack of resources and tools for COPD prevention, diagnosis, and follow-up, 5) lack of communication tools, 6) lack of integration of the patient-as-partner approach, and 7) lack of adaptation of patient education to their specific needs. Multiple strategies were proposed to improve healthcare professionals’ education and interprofessional collaboration and communication.

Conclusion

QI collaborative activities can support achieving understanding of QI challenges healthcare organizations face to improve COPD services.

Developing a Multidisciplinary Approach to the COPD Care Pathway

Chronic obstructive pulmonary disease (COPD) is characterized as a predominately preventable and treatable inflammatory lung disease caused by progressive obstructed airflow from the lungs. In the United States and worldwide, it is becoming a major cause in hospital admissions as well as an increase in morbidity and mortality. The rising total cost of care for COPD is concerning for all health care industries. The disease has significant impact on the patient's quality of life and psychological well-being. A worldwide initiative is underway in developing a care model that is multifactorial through continuous monitoring of patients to manage and control symptoms, achieve medication adherence, and provide socioeconomic resources. The primary aim of this study was to prevent exacerbations, hospital admissions, and readmissions. Various models have shown positive results; however, the significant financial investment is the major barrier to success. Recently, one health system in the United States was able to improve care, decrease readmissions, and reduce total cost of care by investing in a multidisciplinary team of specialists. In the utilization of the care model, the primary endpoint will conclude that COPD is financially and socioeconomically manageable.

Cost-effectiveness of a telemonitoring program (telEPOC program) in frequently admitted chronic obstructive pulmonary disease patients

Chronic obstructive pulmonary disease is a typical disease among chronic and respiratory diseases. The costs associated with chronic disease care are rising dramatically, and this makes it necessary to redesign care processes, including new tools which allow the health system to be more sustainable without compromising on the quality of the care, compared to that currently provided. One approach may be to use information and communication technologies. In this context, we explored the cost-effectiveness of applying a telemonitoring system to a cohort of chronic obstructive pulmonary disease patients with frequent readmissions (the telEPOC programme).We conducted an intervention study with a control group. The inclusion criteria used were having chronic obstructive pulmonary disease (forced expiratory volume in the first second/forced vital capacity  < 70%) and having been hospitalised for exacerbation at least twice in the last year or three times in the last 2 years. We estimated the costs incurred by patients in each group and calculated the quality-adjusted life years and incremental cost-effectiveness ratio.Overall, 77 patients were included in the control group and 86 in the intervention group. The raw cost-effectiveness analysis showed that the cost of the telEPOC intervention was significantly lower than that of usual care, while there were no significant differences between the groups in effectiveness.The incremental cost-effectiveness ratio for the intervention was €175,719.71 per quality-adjusted life-year gained.There were no differences between the intervention group (telemonitoring) and the control group (standard care) from the cost-effectiveness point of view. On the other hand, the intervention programme (telEPOC) was less expensive than routine clinical practice.

Renewed vision on pulmonary rehabilitation service delivery for chronic obstructive pulmonary disease management beyond COVID-19

Pulmonary rehabilitation (PR) is a cornerstone management for chronic obstructive pulmonary disease (COPD). International respiratory societies defined PR is more than "just an exercise program"; it is a comprehensive care delivered by a team of dedicated healthcare professionals with a strong emphasis on long-term health-enhancing Behaviors. However, "Uncertainty" exists with varied reasons for the political and geographical barriers of referral, uptake, attendance, and completion of PR in both primary and secondary care. Besides, COVID-19 pandemic has sparked many global controversies and challenges on pulmonary rehabilitation service delivery. Post-COVID-19 guidelines emphasize on integrated care rehabilitation for patients with COPD. Thus, this concise review intends to understand the gaps in United Kingdom healthcare policies, practices, and PR services resources. To date, there is no clear consensus on PR integrated care model pathway to address the unmet needs, measure the health and social care disparities; adds to the disease burden of COPD. Based on the culmination of evidence, this perspective offers a theoretical framework of PR integrated service model, a pathway to deliver high-value personalized care to patients with COPD.

Treatable traits qualifying for nonpharmacological interventions in COPD patients upon first referral to a pulmonologist: the COPD sTRAITosphere

Introduction

The present study assessed the prevalence of nine treatable traits (TTs) pinpointing nonpharmacological interventions in patients with COPD upon first referral to a pulmonologist, how these TTs co-occurred and whether and to what extent the TTs increased the odds having a severely impaired health status.

Methods

Data were collected from a sample of 402 COPD patients. A second sample of 381 patients with COPD was used for validation. Nine TTs were assessed: current smoking status, activity-related dyspnoea, frequent exacerbations <12 months, severe fatigue, depressed mood, poor physical capacity, low physical activity, poor nutritional status and a low level of self-management activation. For each TT the odds ratio (OR) of having a severe health status impairment was calculated. Furthermore, a graphic representation was created, the COPD sTRAITosphere, to visualise TTs prevalence and OR.

Results

On average 3.9±2.0 TTs per patient were observed. These TTs occurred relatively independently of each other and coexisted in 151 unique combinations. A significant positive correlation was found between the number of TTs and Clinical COPD Questionnaire total score (r=0.58; p<0.001). Patients with severe fatigue (OR: 8.8), severe activity-related dyspnoea (OR: 5.8) or depressed mood (OR: 4.2) had the highest likelihood of having a severely impaired health status. The validation sample corroborated these findings.

Conclusions

Upon first referral to a pulmonologist, COPD patients show multiple TTs indicating them to several nonpharmacological interventions. These TTs coexist in many different combinations, are relatively independent and increase the likelihood of having a severely impaired health status.

The clinical effectiveness of the COPDnet integrated care model

RATIONALE

Integrated care models have the potential to improve outcomes for patients with COPD. We therefore designed the COPDnet integrated care model and implemented it in two hospitals and affiliated primary care regions in the Netherlands. The COPDnet model consists of a comprehensive diagnostic trajectory ran in secondary care followed by a non-pharmacological intervention program of both monodisciplinary and multidisciplinary components.

OBJECTIVE

To assess the clinical effectiveness of the COPDnet integrated care model on health status change in patients with COPD.

METHODS

A total of 402 patients with COPD were offered care according to the COPDnet model. At baseline and between 7- and 9-months later health status was measured with the Clinical COPD Questionnaire (CCQ). Primary analysis was carried out for the sample at large. In addition, subgroup analyses were performed after stratification for the type of non-pharmacological intervention where patients had been referred to.

RESULTS

The CCQ total score improved statistically significantly from 1.94 ± 1.04 to 1.73 ± 0.96 (P < 0.01) in the 154 patients with valid follow-up measurements. Subgroup analyses revealed significant improvements in the patients receiving pulmonary rehabilitation only. No change in health status was found in patients receiving pharmacotherapy only, carried out self-treatment or who participated in mono-disciplinary primary care offered by allied healthcare professionals.

CONCLUSIONS

An improved health status was found in patients with COPD who received care according to the COPDnet integrated care model. Subgroups participating in an interdisciplinary pulmonary rehabilitation program predominantly accounted for this effect.

Health Care Utilisation and Health Needs of People with Severe COPD in the Southern Region of New Zealand: A Retrospective Case Note Review

We examined health care utilisation and needs of people with severe COPD in the low-population-density setting of the Southern Region of New Zealand (NZ). We undertook a retrospective case note review of patients with COPD coded as having an emergency department attendance and/or admission with at least one acute exacerbation during 2015 to hospitals in the Southern Region of NZ. Data were collected and analysed from 340 case notes pertaining to: demographics, hospital admissions, outpatient contacts, pulmonary rehabilitation, advance care planning and comorbidities. Geometric mean (95%CI) length of stay for hospital admissions in urban and rural hospitals was 3.0 (2.7-3.4) and 4.0 (2.9-5.4) days respectively. More patients were from areas of higher deprivation but median hospital length of stay for patients from the least deprived areas was 2.0 days longer than others (p = 0.04). There was a median of 4 (range 0-16) comorbidities and 10 medications (range 0-25) per person. Of 169 cases where data was available, 26 (15%) were offered, 17 (10%) declined, and 5 (3%) completed, pulmonary rehabilitation at or in the year prior to the index admission. Patients were less likely to be offered pulmonary rehabilitation if they lived >20km away from the hospital where it took place (odds ratio of 0.12 for those living further away [95%CI 0.02-0.93, p = 0.04]). There were deficits in care: provision and uptake of non-pharmacological interventions was suboptimal and unevenly distributed across the region. Further research is needed to develop and evaluate strategies for delivering non-pharmacological interventions in this setting.

Development of a Standard Set of Outcome Domains and Proposed Measures for Chronic Obstructive Pulmonary Disease in Primary Care Physical Therapy Practice in the Netherlands: a Modified RAND/UCLA Appropriateness Method

Background

Standardization of measures in a common set opens the opportunity to learn from differences in treatment outcomes which can be used for improving the quality of care. Furthermore, a standard set can provide the basis for development of quality indicators and is therefore useful for quality improvement and public reporting purposes. The aim of this study was to develop a standard set of outcome domains and proposed measures for patients with COPD in Dutch primary care physical therapy practice, including a proposal to stratify patients in subgroups.

Material and methods

A consensus-driven modified RAND-UCLA appropriateness method was conducted with relevant stakeholders (patients, physical therapists, researchers, policy makers and health insurers) in Dutch primary physical therapy care in eight steps: (1) literature search, (2) first online survey, (3) patient interviews, (4) expert meeting, resulting in a concept standard set and methods to identify subgroups' (5) consensus meeting, (6) expert meeting (7) second online survey and (8) final approval of an advisory board resulting of the approved standard set.

Results

Five outcome domains were selected for COPD: physical capacity, muscle strength, physical activity, dyspnea and quality of life. A total of 21 measures were rated and discussed. Finally, eight measures were included, of which four mandatory measures: Characteristics of practices and physical therapists, Clinical COPD Questionnaire (CCQ) for quality of life, Global Perceived Effect (GPE) for experience, 6-mins Walk Test (6-MWT) for physical capacity; two conditional measures: Hand-Held Dynamometer (HHD) (with Microfet™) for Quadriceps strength, Medical Research Council Dyspnea (MRC) for monitoring dyspnea; and two exploratory measures: Accelerometry for physical activity, and the Assessment of Burden of COPD tool (ABC). To identify subgroups, a method described in the Dutch standard of care from the Lung Alliance was included.

Conclusion

This study described the development of a standard set of outcome domains and proposed measures for patients with COPD in primary care physical therapy. Each measure was accepted for relevance and feasibility by the involved stakeholders. The set is currently used in daily practice and tested on validity and reliability in a pilot for the development of quality indicators.

Improving access to health care for people with severe chronic obstructive pulmonary disease (COPD) in Southern New Zealand: qualitative study of the views of health professional stakeholders and patients

OBJECTIVES

Chronic obstructive pulmonary disease (COPD) is a common chronic disease with significant morbidity and mortality, particularly for Māori, which places a large burden on the New Zealand (NZ) health system. We undertook a qualitative study as part of a mixed-methods implementation research project which aimed to determine the barriers and enablers to the provision of accessible high-quality COPD care.

SETTING

Southern Health Region of NZ (Otago and Southland).

PARTICIPANTS

Thirteen health professional stakeholders and 23 patients with severe COPD (including one Māori and one Pasifika participant).

METHODS

Semistructured interviews were undertaken. A thematic analysis using the Levesque conceptual framework for access to healthcare was conducted.

RESULTS

Health professional stakeholders identified barriers to providing access to health services, in particular: availability (inadequate staffing and resourcing of specialist services and limited geographical availability of pulmonary rehabilitation), affordability (both of regular medication, medication needed for an exacerbation of COPD and the copayment charge for seeing a general practitioner) and appropriateness (a shared model of care across primary and secondary care was needed to facilitate better delivery of key interventions such as pulmonary rehabilitation and advance care planning (ACP). Māori stakeholders highlighted the importance of communication and relationships and the role of whānau (extended family) for support. Patients' accounts showed variable ability to access services through having a limited understanding of what COPD is, a limited knowledge of services they could access, being unable to attend pulmonary rehabilitation (due to comorbidities) and direct (medication and copayment charges) and indirect (transport) costs.

CONCLUSIONS

People with severe COPD experience multilevel barriers to accessing healthcare in the NZ health system along the pathway of care from diagnosis to ACP. These need to be addressed by local health services if this group of patients are to receive high-quality care.

Organizational aspects of pulmonary rehabilitation in chronic respiratory diseases

Adult patients with chronic respiratory diseases may suffer from multiple physical (pulmonary and extra-pulmonary), emotional and social features which necessitate a comprehensive, interdisciplinary rehabilitation programme. To date, pulmonary rehabilitation programmes show a lot of variation in setting, content, frequency and duration. Future projects should strive for a standard set of assessment measures to identify patients eligible for pulmonary rehabilitation, taking disease complexity into consideration, which should result in referral to an appropriate rehabilitation setting. Local circumstances may complicate this crucial endeavour.
