An Innovative Patient-Centred Approach to Heart Failure Management: The Best Care Heart Failure Integrated Disease-Management Program.

Background: The management of heart failure (HF) is challenging because of the complexities in recommended therapies. Integrated disease management (IDM) is an effective model, promoting guideline-directed care, but the impact of IDM in the community setting requires further evaluation. Methods: A retrospective evaluation of community-based IDM. Patient characteristics were described, and outcomes using a pre- and post-intervention design were HF-related health-service use, quality of life, and concordance with guideline-directed medical therapy (GDMT). Results: 715 patients were treated in the program (2016 to 2023), 219 in a community specialist-care clinic, and 496 in 25 primary-care clinics. The overall cohort was predominantly male (60%), with a mean age of 73.5 years (± 10.7), and 60% with HF with reduced ejection fraction. In patients with ≥ 6 months of follow-up (n = 267), pre vs post annualized rates of HF-related acute health-service use decreased from 36.3 to 8.5 hospitalizations per 100 patients per year, P < 0.0001, from 31.8 to 13.1 emergency department visits per 100 patients per year, P < 0.0001, and from 152.8 to 110.0 urgent physician visits per 100 patients per year, P = 0.0001. The level of concordance with GDMT improved; the number of patients receiving triple therapy and quadruple therapy increased by 10.1% (95% confidence interval [CI], 2.4%,17.8%) and 19.6% (95% CI, 12.0%, 27.3%), respectively. Within these groups, optimal dosing was achieved in 42.5% (95% CI, 32.0%, 53.6%) and 35.0% (95% CI, 23.1%, 48.4%), respectively. In patients with at least one follow-up visit (n = 286), > 50% experienced a clinically relevant improvement in their quality of life. Conclusions: A community-based IDM program for HF, may reduce HF-related acute health-service use, improve quality of life and level of concordance with GDMT. These encouraging preliminary outcomes from a real-world program evaluation require confirmation in a randomized controlled trial.

Contexte: La prise en charge de l'insuffisance cardiaque (IC) représente un défi en raison de la complexité des traitements recommandés. La prise en charge intégrée des maladies est un modèle efficace qui favorise les soins reposant sur les lignes directrices, mais la portée de ce modèle en milieu extra-hospitalier mérite une évaluation plus approfondie. Méthodologie: Évaluation rétrospective de la prise en charge intégrée des maladies à l'échelle communautaire. Les caractéristiques des patients ont été établies. Les résultats mesurés avant et après l'intervention ont été l'utilisation des services de santé liés à l'IC, la qualité de vie et le degré de concordance avec le traitement médical recommandé par les lignes directrices. Résultats: Au total, 715 patients ont été traités dans le cadre du programme (de 2016 à 2023) : 219 dans une clinique communautaire de soins spécialisés et 496 dans 25 cliniques de soins primaires. Dans l'ensemble, la majorité des patients étaient de sexe masculin (60 %). L'âge moyen était de 73,5 ans (± 10,7 ans). Soixante pour cent des patients présentaient une IC avec fraction d'éjection réduite. Chez les patients ayant fait l'objet d'un suivi pendant ≥ 6 mois (n = 267), les taux annualisés d'utilisation des services de santé aigus liés à l'IC avant et après l'intervention sont passés de 36,3 à 8,5 hospitalisations pour 100 patients par année (p < 0,0001), de 31,8 à 13,1 visites aux urgences pour 100 patients par année (p < 0,0001) et de 152,8 à 110,0 consultations avec un urgentologue pour 100 patients par année (p = 0,0001). On a observé une augmentation du degré de concordance avec le traitement médical recommandé par les lignes directrices. Le nombre de patients recevant une trithérapie et une quadrithérapie a également augmenté de 10,1 % (intervalle de confiance [IC] à 95 % : 2,4 % à 17,8 %) et de 19,6 % (IC à 95 % : 12,0 % à 27,3 %), respectivement. Dans ces groupes, la dose optimale a été atteinte chez 42,5 % (IC à 95 % : 32,0 % à 53,6 %) et 35,0 % (IC à 95 % : 23,1 % à 48,4 %) des patients, respectivement. Plus de 50 % des patients ayant effectué au moins une visite de suivi (n = 286) ont obtenu une amélioration cliniquement pertinente de leur qualité de vie. Conclusions: Un programme communautaire de prise en charge intégrée de l'IC peut réduire l'utilisation des services de santé liés à l'IC, améliorer la qualité de vie et augmenter le degré de concordance avec le traitement médical recommandé par les lignes directrices. Bien qu'ils soient encourageants, ces résultats préliminaires issus de l'évaluation d'un programme en contexte réel doivent être confirmés par la réalisation d'une étude à répartition aléatoire et contrôlée.

Quantifying sustained health system benefits of primary care-based integrated disease management for COPD: a 6-year interrupted time series study.

BACKGROUND: Severe exacerbation of chronic obstructive pulmonary disease (COPD) is a trajectory-changing life event for patients and a major contributor to health system costs. This study evaluates the real-world impact of a primary care, integrated disease management (IDM) programme on acute health service utilisation (HSU) in the Canadian health system. METHODS: Interrupted time series analysis using retrospective health administrative data, comparing monthly HSU event rates 3 years prior to and 3 years following the implementation of COPD IDM. Primary outcomes were COPD-related hospitalisation and emergency department (ED) visits. Secondary outcomes included hospital bed days and all-cause HSU. RESULTS: There were 2451 participants. COPD-related and all-cause HSU rates increased in the 3 years prior to IDM implementation. With implementation, there was an immediate decrease (month 1) in COPD-related hospitalisation and ED visit rates of -4.6 (95% CI: -7.76 to -1.39) and -6.2 (95% CI: -11.88, -0.48) per 1000 participants per month, respectively, compared with the counterfactual control group. After 12 months, COPD-related hospitalisation rates decreased: -9.1 events per 1000 participants per month (95% CI: -12.72, -5.44) and ED visits -19.0 (95% CI: -25.50, -12.46). This difference nearly doubled by 36 months. All-cause HSU also demonstrated rate reductions at 12 months, hospitalisation was -10.2 events per 1000 participants per month (95% CI: -15.79, -4.44) and ED visits were -30.4 (95% CI: -41.95, -18.78). CONCLUSIONS: Implementation of COPD IDM in a primary care setting was associated with a changed trajectory of COPD-related and all-cause HSU from an increasing year-on-year trend to sustained long-term reductions. This highlights a substantial real-world opportunity that may improve health system performance and patient outcomes.

Cost-effectiveness of integrated disease management for high risk, exacerbation prone, patients with chronic obstructive pulmonary disease in a primary care setting.

BACKGROUND: We evaluate the cost-effectiveness of the 'Best Care' integrated disease management (IDM) program for high risk, exacerbation prone, patients with chronic obstructive pulmonary disease (COPD) compared to usual care (UC) within a primary care setting from the perspective of a publicly funded health system (i.e., Ontario, Canada). METHODS: We conducted a model-based, cost-utility analysis using a Markov model with expected values of costs and outcomes derived from a Monte-Carlo Simulation with 5000 replications. The target population included patients started in GOLD II with a starting age of 68 years in the trial-based analysis. Key input parameters were based on a randomized control trial of 143 patients (i.e., UC (n = 73) versus IDM program (n = 70)). Results were shown as incremental cost per quality-adjusted life year (QALY) gained. RESULTS: The IDM program for high risk, exacerbation prone, patients is dominant in comparison with the UC group. After one year, the IDM program demonstrated cost savings and improved QALYs (i.e., UC was dominated by IDM) with a positive net-benefit of $5360 (95% CI: ($5175, $5546) based on a willingness to pay of $50,000 (CAN) per QALY. CONCLUSIONS: This study demonstrates that the IDM intervention for patients with COPD in a primary care setting is cost-effective in comparison to the standard of care. By demonstrating the cost-effectiveness of IDM, we confirm that investment in the delivery of evidence based best practices in primary care delivers better patient outcomes at a lower cost than UC.

Primary care-based integrated disease management for heart failure: a study protocol for a cluster randomised controlled trial.

INTRODUCTION: Heart failure (HF) is a common chronic disease that increases in prevalence with age. It is associated with high hospitalisation rates, poor quality of life and high mortality. Management is complex with most interactions occurring in primary care. Disease management programmes implemented during or after an HF hospitalisation have been shown to reduce hospitalisation and mortality rates. Evidence for integrated disease management (IDM) serving the primary care HF population has been investigated but is less conclusive. The aim of this study is to evaluate the efficacy of IDM, focused on, optimising medication, self-management and structured follow-up, in a high-risk primary care HF population. METHODS AND ANALYSIS: 100 family physician clusters will be recruited in this Canadian primary care multicentre cluster randomised controlled trial. Physicians will be randomised to IDM or to care as usual. The IDM programme under evaluation will include case management, medication management, education, and skills training delivered collaboratively by the family physician and a trained HF educator. The primary outcome will measure the combined rate (events/patient-years) of all-cause hospitalisations, emergency department visits and mortality over a 12-month follow-up. Secondary outcomes include other health service utilisation, quality of life, knowledge assessments and acute HF episodes. Two to three HF patients will be recruited per physician cluster to give a total sample size of 280. The study has 90% power to detect a 35% reduction in the primary outcome. The difference in primary outcome between IDM and usual care will be modelled using a negative binomial regression model adjusted for baseline, clustering and for individuals experiencing multiple events. ETHICS AND DISSEMINATION: The study has obtained approval from the Research Ethics Board at the University of Western Ontario, London, Canada (ID 114089). Findings will be disseminated through local reports, presentations and peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT04066907.

Confronting complexity and supporting transformation through health systems mapping: a case study.

INTRODUCTION: Health systems are a complex web of interacting and interconnected parts; introducing an intervention, or the allocation of resources, in one sector can have effects across other sectors and impact the entire system. A prerequisite for effective health system reorganisation or transformation is a broad and common understanding of the current system amongst stakeholders and innovators. Chronic obstructive pulmonary disease (COPD) and heart failure (HF) are common chronic diseases with high health care costs that require an integrated health system to effectively treat. STUDY DESCRIPTION: This case study documents the first phase of system transformation at a regional level in Ontario, Canada. In this first phase, visual representations of the health system in its current state were developed using a collaborative co-creation approach, and a focus on COPD and HF. Multiple methods were used including focus groups, open-ended questionnaires, and document review, to develop a series of graphical and visual representations; a health care ecosystem map. RESULTS: The ecosystem map identified key sectoral components, inter-component interactions, and care requirements for patients with COPD and HF and inventoried current programs and services available to deliver this care. Main findings identified that independent system-wide navigation for this vulnerable patient group is limited, primary care is central to the accessibility of nearly half of the identified care elements, and resources are not equitably distributed. The health care ecosystem mapping helped to identify care gaps and illustrates the need to resource the primary care provider and the patient with system navigation resources and interdisciplinary team care. CONCLUSION: The co-created health care ecosystem map brought a collective understanding of the health care system as it applies to COPD and HF. The map provides a blueprint that can be adapted to other disease states and health systems. Future transformation will build on this foundational work, continuing the robust interdisciplinary co-creation strategies, exploring predictive health system modelling and identifying areas for integration.

Evaluating the implementation of a chronic obstructive pulmonary disease management program using the Consolidated Framework for Implementation Research: a case study.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a prevalent chronic disease that requires comprehensive approaches to manage; it accounts for a significant portion of Canada's annual healthcare spending. Interprofessional teams are effective at providing chronic disease management that meets the needs of patients. As part of an ongoing initiative, a COPD management program, the Best Care COPD program was implemented in a primary care setting. The objectives of this research were to determine site-specific factors facilitating or impeding the implementation of a COPD program in a new setting, while evaluating the implementation strategy used. METHODS: A qualitative case study was conducted using interviews, focus groups, document analysis, and site visits. Data were deductively analyzed using the Consolidated Framework for Implementation Research (CFIR) to assess the impact of each of its constructs on Best Care COPD program implementation at this site. RESULTS: Eleven CFIR constructs were determined to meaningfully affect implementation. Five were identified as the most influential in the implementation process. Cosmopolitanism (partnerships with other organizations), networks and communication (amongst program providers), engaging (key individuals to participate in program implementation), design quality and packaging (of the program), and reflecting and evaluating (throughout the implementation process). A peer-to-peer implementation strategy included training of registered respiratory therapists (RRT) as certified respiratory educators and the establishment of a communication network among RRTs to discuss experiences, collectively solve problems, and connect with the program lead. CONCLUSIONS: This study provides a practical example of the various factors that facilitated the implementation of the Best Care COPD program. It also demonstrates the potential of using a peer-to-peer implementation strategy. Focusing on these factors will be useful for informing the continued spread and success of the Best Care COPD program and future implementation of other chronic care programs.

Integrated Disease Management for Chronic Obstructive Pulmonary Disease in Primary Care, from the Controlled Trial to Clinical Program: A Cohort Study.

PURPOSE: Integrated disease management (IDM) for COPD in primary care has been primarily investigated under clinical trial conditions. We previously published a randomized controlled trial (RCT) where the IDM intervention improved quality of life (QoL) and exacerbation-related outcomes. In this study, we assess the same IDM intervention in a real-world evaluation and identify patient characteristics associated with improved outcomes. METHODS: This historical cohort study included patients enrolled for 12 (±3 months) in the Best Care COPD IDM program. The main outcome was a ≥3 point improvement in COPD assessment test (CAT). Secondary outcomes were COPD exacerbations requiring antibiotics and/or prednisone, unscheduled physician visits, emergency department visits and hospitalizations. RESULTS: Data for 571 patients (all patients) were included, 158 met the reference RCT eligibility (RCT matched). Improved QoL was observed in 43% (95% CI:38.9,47.2) of all patients, 47% (95% CI:39.5,55.6) of RCT matched vs 92% (95% CI:79.2,95.1) in the reference RCT intervention arm (n=72). Reductions (12 months IDM vs prior year) were observed in the proportion of patients experiencing exacerbation-related events (all patients): antibiotics/prednisone (-9.0%,95% CI:-13.9,-3.9); unscheduled physician (-33.1%,95% CI:-38.2,-27.9); emergency department (-9.6%,95% CI:-13.5,-5); and hospitalizations (-6.8%,95% CI:-10.0,-3.7). For the RCT matched group all reductions were comparable to the reference RCT intervention arm. The strongest predictors of improved QoL were baseline CAT, CAT≥20 vs CAT<10 (OR 15.6,95% CI:7.91,30.83), GOLD group B (OR 6.4,95% CI:3.42,11.85) and D (OR 5.64,95% CI:2.80,11.37) vs GOLD group A. Patients with prior antibiotic/prednisone use, FEV1 <30% predicted and GOLD group D were less likely to have no urgent health service utilization (OR 0.5,95% CI:0.30,0.68), (OR 0.2,95% CI:0.07,0.78) and (OR 0.3,95% CI:0.14,0.51), respectively. CONCLUSION: Best Care COPD improved QoL and reduced exacerbation-related outcomes in a manner directionally similar to the RCT from which it emanated. Baseline QoL, exacerbation history, and GOLD category were identified as possible predictors of IDM impact and will inform future program development and resource allocation.

The impact of integrated disease management in high-risk COPD patients in primary care.

Patients with chronic obstructive pulmonary disease (COPD) have a reduced quality of life (QoL) and exacerbations that drive health service utilization (HSU). A majority of patients with COPD are managed in primary care. Our objective was to evaluate an integrated disease management, self-management, and structured follow-up intervention (IDM) for high-risk patients with COPD in primary care. This was a one-year multi-center randomized controlled trial. High-risk, exacerbation-prone COPD patients were randomized to IDM provided by a certified respiratory educator and physician, or usual physician care. IDM received case management, self-management education, and skills training. The primary outcome, COPD-related QoL, was measured using the COPD Assessment Test (CAT). Of 180 patients randomized from 8 sites, 81.1% completed the study. Patients were 53.6% women, mean age 68.2 years, post-bronchodilator FEV1 52.8% predicted, and 77.4% were Global Initiative for Obstructive Lung Disease Stage D. QoL-CAT scores improved in IDM patients, 22.6 to 14.8, and worsened in usual care, 19.3 to 22.0, adjusted difference 9.3 (p < 0.001). Secondary outcomes including the Clinical COPD Questionnaire, Bristol Knowledge Questionnaire, and FEV1 demonstrated differential improvements in favor of IDM of 1.29 (p < 0.001), 29.6% (p < 0.001), and 100 mL, respectively (p = 0.016). Compared to usual care, significantly fewer IDM patients had a severe exacerbation, -48.9% (p < 0.001), required an urgent primary care visit for COPD, -30.2% (p < 0.001), or had an emergency department visit, -23.6% (p = 0.001). We conclude that IDM self-management and structured follow-up substantially improved QoL, knowledge, FEV1, reduced severe exacerbations, and HSU, in a high-risk primary care COPD population.

A Patient-Centered Mobile Health System That Supports Asthma Self-Management (breathe): Design, Development, and Utilization.

BACKGROUND: Uncontrolled asthma poses substantial negative personal and health system impacts. Web-based technologies, including smartphones, are novel means to enable evidence-based care and improve patient outcomes. OBJECTIVE: The aim of this study was to design, develop, and assess the utilization of an asthma collaborative self-management (CSM) platform (breathe) using content based on international evidence-based clinical guidelines. METHODS: We designed and developed breathe as a Web-based mobile health (mHealth) platform accessible on smartphones, tablets, or desktop with user-centered design methods and International Organization for Standardization-certified quality development processes. Moreover, breathe was envisioned as a multifunctional, CSM mHealth platform, with content based on international clinical practice guidelines and compliant with national privacy and security specifications. The system enabled CSM (patient, provider, and breathe) and self-monitoring of asthma patients through (1) assessment of asthma control, (2) real-time access to a dynamic asthma action plan, (3) access to real-time environmental conditions, and (4) risk-reduction messaging. The data collection protocol collected user data for 12 months, with clinic visits at baseline and 6 and 12 months. Utilization outcomes included user interactions with the platform, user impressions, self-reported medication use, asthma symptom profile, reported peak flow measurement, and the delivery and impact of email reminders. RESULTS: We enrolled 138 patients with a mean age of 45.3 years to receive the breathe intervention. Majority were female (100/138, 72.5%), had a smartphone (92/138, 66.7%), and had a mean Asthma Control Test score of 18.3 (SD 4.9). A majority reported that breathe helped in the management of their asthma. Moreover, breathe scored 71.1 (SD 18.9) on the System Usability Scale. Overall, 123 patients had complete usage analytics datasets. The platform sent 7.96 reminder emails per patient per week (pppw), patients accessed breathe 3.08 times, journaled symptoms 2.56 times, reported medication usage 0.30 times, and reported peak flow measurements 0.92 times pppw. Furthermore, breathe calculated patients' action plan zone of control 2.72 times pppw, with patients being in the green (well-controlled) zone in 47.71% (8300/17,396) of the total calculations. Usage analysis showed that 67.5% (83/123) of the participants used the app at week 4 and only 57.7% (71/123) by week 45. Physician visits, email reminders, and aged 50 years and above were associated with higher utilization. CONCLUSIONS: Individuals with asthma reported good usability and high satisfaction levels, reacted to breathe notifications, and had confidence in the platform's assessment of asthma control. Strong utilization was seen at the intervention's initiation, followed by a rapid reduction in use. Patient reminders, physician visits, and being aged 50 years and above were associated with higher utilization.

Development and pilot testing of a mobile health solution for asthma self-management: asthma action plan smartphone application pilot study.

BACKGROUND: Collaborative self-management is a core recommendation of national asthma guidelines; the written action plan is the knowledge tool that supports this objective. Mobile health technologies have the potential to enhance the effectiveness of the action plan as a knowledge translation tool. OBJECTIVE: To design, develop and pilot a mobile health system to support asthma self-management. METHODS: The present study was a prospective, single-centre, nonrandomized, pilot preintervention-postintervention analysis. System design and development were guided by an expert steering committee. The network included an agnostic web browser-based asthma action plan smartphone application (SPA). Subjects securely transmitted symptoms and peak flow data daily, and received automated control assessment, treatment advice and environmental alerts. RESULTS: Twenty-two adult subjects (mean age 47 years, 82% women) completed the study. Biophysical data were received on 84% of subject days (subject day = 1 subject × 1 day). Subjects viewed their action plan current zone of control on 54% and current air quality on 61% of subject days, 86% followed self-management advice and 50% acted to reduce exposure risks. A large majority affirmed ease of use, clarity and timeliness, and 95% desired SPA use after the study. At baseline, 91% had at least one symptom criterion for uncontrolled asthma and 64% had ≥2, compared with 45% (P=0.006) and 27% (P=0.022) at study close. Mean Asthma Quality of Life Questionnaire score improved from 4.3 to 4.8 (P=0.047). CONCLUSIONS: A dynamic, real-time, interactive, mobile health system with an integrated asthma action plan SPA can support knowledge translation at the patient and provider levels.

Spirometry in primary care: an analysis of spirometery test quality in a regional primary care asthma program.

BACKGROUND: Primary care office spirometry can improve access to testing and concordance between clinical practice and asthma guidelines. Compliance with test quality standards is essential to implementation. OBJECTIVE: To evaluate the quality of spirometry performed onsite in a regional primary care asthma program (RAP) by health care professionals with limited training. METHODS: Asthma educators were trained to perform spirometry during two 2 h workshops and supervised during up to six patient encounters. Quality was analyzed using American Thoracic Society (ATS) 1994 and ATS/European Respiratory Society (ERS) 2003 (ATS/ERS) standards. These results were compared with two regional reference sites: a primary care group practice (Family Medical Centre [FMC], Windsor, Ontario) and a teaching hospital pulmonary function laboratory (London Health Sciences Centre [LHSC], London, Ontario). RESULTS: A total of 12,815 flow-volume loops (FVL) were evaluated: RAP - 1606 FVL in 472 patient sessions; reference sites - FMC 4013 FVL in 573 sessions; and LHSC - 7196 in 1151 sessions. RAP: There were three acceptable FVL in 392 of 472 (83%) sessions, two reproducible FVL according to ATS criteria in 428 of 469 (91%) sessions, and 395 of 469 (84%) according to ATS/ERS criteria. All quality criteria - minimum of three acceptable and two reproducible FVL according to ATS criteria in 361 of 472 (77%) sessions and according to ATS/ERS criteria in 337 of 472 (71%) sessions. RAP met ATS criteria more often than the FMC (388 of 573 [68%]); however, less often than LHSC (1050 of 1151 [91%]; P<0.001). CONCLUSIONS: Health care providers with limited training and experience operating within a simple quality program achieved ATS/ERS quality spirometry in the majority of sessions in a primary care setting. The quality performance approached pulmonary function laboratory standards.
