An economic evaluation of chronic obstructive pulmonary disease clinical pathway in Saskatchewan, Canada: Data-driven techniques to identify cost-effectiveness among patient subgroups.

[PMID: 38557914 PMCID: PMC10984414 DOI: 10.1371/journal.pone.0301334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 03/12/2024] [Indexed: 04/04/2024] Open
Abstract
BACKGROUND Saskatchewan has implemented care pathways for several common health conditions. To date, there has not been any cost-effectiveness evaluation of care pathways in the province. The objective of this study was to evaluate the real-world cost-effectiveness of a chronic obstructive pulmonary disease (COPD) care pathway program in Saskatchewan. METHODS Using patient-level administrative health data, we identified adults (35+ years) with COPD diagnosis recruited into the care pathway program in Regina between April 1, 2018, and March 31, 2019 (N = 759). The control group comprised adults (35+ years) with COPD who lived in Saskatoon during the same period (N = 759). The control group was matched to the intervention group using propensity scores. Costs were calculated at the patient level. The outcome measure was the number of days patients remained without experiencing COPD exacerbation within 1-year follow-up. Both manual and data-driven policy learning approaches were used to assess heterogeneity in the cost-effectiveness by patient demographic and disease characteristics. Bootstrapping was used to quantify uncertainty in the results. RESULTS In the overall sample, the estimates indicate that the COPD care pathway was not cost-effective using the willingness to pay (WTP) threshold values in the range of $1,000 and $5,000/exacerbation day averted. The manual subgroup analyses show the COPD care pathway was dominant among patients with comorbidities and among patients aged 65 years or younger at the WTP threshold of $2000/exacerbation day averted. Although similar profiles as those identified in the manual subgroup analyses were confirmed, the data-driven policy learning approach suggests more nuanced demographic and disease profiles that the care pathway would be most appropriate for. CONCLUSIONS Both manual subgroup analysis and data-driven policy learning approach showed that the COPD care pathway consistently produced cost savings and better health outcomes among patients with comorbidities or among those relatively younger. The care pathway was not cost-effective in the entire sample.

Abstract
An integrated disease management program otherwise called a clinical pathway was recently implemented in Saskatchewan, Canada for patients living with chronic obstructive pulmonary disease (COPD). This study compared the real-world costs and consequences of the COPD clinical pathway program with 2 control treatment programs. The study comprised adult COPD patients in Regina (clinical pathway group, N = 759) matched on propensity scores to 2 independent control groups of similar adults in (1) Regina (historical controls, N = 759) and (2) Saskatoon (contemporaneous controls, N = 759). The study measures included patient-level healthcare costs and acute COPD exacerbation outcomes, both tracked in population-based administrative health data over a one-year follow-up period. Analyses included Cox proportional hazards models and differences in means between groups. The bias-corrected and accelerated bootstrap method was used to calculate 95% confidence intervals (CI). The COPD pathway patients had lower risks of moderate (hazard ratio [HR] =0.57, 95% CI [0.40-0.83]) and severe (HR = 0.43, 95% CI [0.28-0.66]) exacerbations compared to the historical control group, but similar risks compared with the contemporaneous control group. The COPD pathway patients experienced fewer episodes of exacerbations compared with the historical control group (mean difference = -0.30, 95% CI [-0.40, -0.20]) and the contemporaneous control group (mean difference = -0.12, 95% CI [-0.20, -0.03]). Average annual healthcare costs in Canadian dollars were marginally higher among patients in the COPD clinical pathway (mean = $10 549, standard deviation [SD] =$18 149) than those in the contemporaneous control group ($8841, SD = $17 120), but comparable to the historical control group ($10 677, SD = $21 201). The COPD pathway provides better outcomes at about the same costs when compared to the historical controls, but only slightly better outcomes and at a marginally higher cost when compared to the contemporaneous controls.

Abstract
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.

Abstract
BACKGROUND The health sector in Poland is currently facing challenges such as limited financial resources, poor infrastructure, and insufficient human resources. To address these issues, increasing cost-effectiveness at the individual physician level has become essential. This study aimed to evaluate the efficiency and effectiveness of patient care at the level of individual primary health care physicians and to compare the performance of physicians working in urban and rural areas. MATERIAL AND METHODS Thirteen original effectiveness indicators were developed based on a literature review, expert consultations, and a pilot study at the Medical and Diagnostic Center in Siedlce. The indicators were used to evaluate the effectiveness of physicians and compare physicians' characteristics working in rural and urban areas. The study extracted data on physicians' characteristics and used the indicators to evaluate their effectiveness. RESULTS Physicians working in rural areas treated more patients due to staff shortages. However, physicians working in urban areas demonstrated greater effectiveness in performing routine and advanced health checks and mammograms. Despite this advantage, the average life expectancy of patients was higher among patients of physicians working in rural areas. CONCLUSIONS Five indicators developed in the study formed a scale, which is a step toward developing a uniform effectiveness indicator. Further research on consistently measuring effectiveness could significantly impact the development of sociometric research methodology. This study highlights the differences in efficiency and effectiveness of physicians working in rural vs urban areas and underscores the need for healthcare policymakers to consider these differences in addressing healthcare resource allocation.

Cost-effectiveness of integrated disease management for high risk, exacerbation prone, patients with chronic obstructive pulmonary disease in a primary care setting. COST EFFECTIVENESS AND RESOURCE ALLOCATION 2022; 20:39. [PMID: 35962399 PMCID: PMC9373353 DOI: 10.1186/s12962-022-00377-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Accepted: 07/27/2022] [Indexed: 11/24/2022] Open
Abstract
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. Supplementary Information The online version contains supplementary material available at 10.1186/s12962-022-00377-w. Interventions that can reduce the frequency and severity of exacerbations in patients who suffer from COPD have the potential to reduce the financial burden of COPD on the health system; This is the first study that demonstrates the cost-effectiveness of integrated disease management for patients who suffer from COPD within a primary care environment; This study makes the case for embedding Certified Respiratory Educators (CREs) within the primary care environment to improve the quality of life of patients who suffer from COPD, as well as alleviating unnecessary health services utilization and decreasing the overall financial burden of the disease on the health system.

Abstract
PURPOSE This study aimed to investigate the relationship between chronic obstructive pulmonary disease (COPD) and postoperative complications for patients receiving distal radius fracture (DRF) open reduction internal fixation (ORIF). METHODS From 2007 to 2018, patients undergoing operative treatment for distal radius fracture were identified in the National Surgical Quality Improvement Program database. Patients were separated into 2 cohorts: non-COPD and COPD patients. In this analysis, thirty-day postoperative complications evaluated included wound, cardiac, pulmonary, renal, thromboembolic, sepsis, mortality, urinary tract infections, postoperative transfusion, extended length of stay, reoperation, and readmission. Bivariate and multivariate analyses were performed. RESULTS Of 12,424 total patients who underwent operative treatment for distal radius fracture, 11,957 patients (96.2%) did not have a diagnosis of COPD and 467 (3.8%) had COPD. Following adjustment, compared to patients who did not have COPD, those with COPD had an increased risk of any postoperative complications (OR 2.160; p = 0.010), postoperative transfusion requirement (OR 17.437; p = 0.001), extended length of hospital stay greater than 3 days (OR 1.564; p = 0.038), and readmission (OR 2.515; p < 0.001). CONCLUSION COPD is an independent risk factor for any postoperative complication including transfusions, extended length of stay, and readmission for patients receiving DRF ORIF. Pulmonary evaluation would be a critical step in preoperative management and counseling of these patients before DRF ORIF.

Abstract
Background Care guidelines for people with chronic obstructive pulmonary disease (COPD) recommend an integrated approach for holistic, flexible, and tailored interventions. Continuity of care is also emphasised. However, many patients with COPD experience fragmented care. Discontinuities in healthcare and related social services are likely to result in disjointed rather than integrated care which can negatively affect patient health outcomes. The purpose of this qualitative study was to improve our understanding of, and how, contextual features pertaining to structures and processes of COPD integrated care influence delivery of care within patients’ healthcare networks. Methods We conducted individual interviews with 28 participants (9 patients, 16 healthcare professionals, and 3 spousal caregivers). Participants were recruited through the lung clinic at a city hospital in western Canada. We employed a social network paradigm to analyse and interpret the data. Results The analysis revealed an overarching theme of fragmented COPD care with two sub-themes: (1) Funding shortfalls and availability of resources, and (2) Dis(mis)connected communication pathways. The overarching theme depicts variations, delays, and discontinuities in patient care. The sub-themes describe how macro level influences and meso level shortfalls were perceived to influence the availability of respiratory care resources that contributed to fragmented COPD care. Conclusions Employing a social network lens drew particular attention to family physicians’ pivotal role in delivering community-based COPD care. While an integrated approach to care is recommended by care guidelines, institutional and organizational structures and processes, such as financial and communication structures, may inhibit delivery of integrated care. Thus, macro and meso level structures and processes have the potential to shape patient care by constraining family physicians’ purposive and communication actions necessary for facilitating an integrated distributed approach to care. We propose a context of care which fosters a context for family physicians’ delivery of patient-centered care. Integrated care delivery may improve patients’ wellbeing and alleviate financial constraints on the healthcare system.

Abstract
OBJECTIVES Important links between dietary patterns and diseases have been widely applied to establish nutrition interventions. However, knowledge about between-person heterogeneity regarding the benefits of nutrition intervention can be used to personalize the intervention and thereby improve health outcomes and efficiency. We performed a systematic review of cost-effectiveness analyses (CEAs) of interventions with a personalized nutrition (PN) component to assess their methodology and findings. METHODS A systematic search (March 2019) was performed in 5 databases: EMBASE, Medline Ovid, Web of Science, Cochrane CENTRAL, and Google Scholar. CEAs involving interventions in adults with a PN component were included; CEAs focusing on clinical nutrition or undernutrition were excluded. The CHEERS checklist was used to assess the quality of CEAs. RESULTS We identified 49 eligible studies among 1792 unique records. Substantial variation in methodology was found. Most studies (91%) focused only on psychological concepts of PN such as behavior and preferences. Thirty-four CEAs were trial-based, 13 were modeling studies, and 4 studies were both trial- and model-based. Thirty-two studies used quality-adjusted life year as an outcome measure. Different time horizons, comparators, and modeling assumptions were applied, leading to differences in costs/quality-adjusted life years. Twenty-eight CEAs (49%) concluded that the intervention was cost-effective, and 75% of the incremental cost-utility ratios were cost-effective given a willingness-to-pay threshold of $50 000 per quality-adjusted life year. CONCLUSIONS Interventions with PN components are often evaluated using various types of models. However, most PN interventions have been considered cost-effective. More studies should examine the cost-effectiveness of PN interventions that combine psychological and biological concepts of personalization.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the United States (US), with West Virginia bearing a disproportionate disease burden. Complex COPD cases can be difficult to manage during a standard primary care provider (PCP) visit, and pharmacological treatment regimens should be individually tailored to each patient. METHODS To address these needs, the West Virginia University Department of Family Medicine created an interdisciplinary COPD specialty clinic that uses a team-based approach to treat patients with COPD. In order to evaluate the effectiveness of the specialty clinic, we conducted a retrospective chart review to examine the impact of the clinic on patient hospitalizations, emergency department visits, and urgent care visits six months and one year before and after initiating care at the clinic. We also examined the impact of the clinic on patients' self-reported nicotine dependency, COPD symptoms, and tobacco use behavior. Patients referred to the clinic and having at least one visit from February 2015 to February 2019 were included in this study (n = 149). RESULTS Patients treated at the COPD specialty clinic had significantly fewer hospital admissions and ED visits six months after and one year after initiating care at the clinic as compared to six months before and one year before, respectively. Patients at this clinic also reported smoking significantly fewer cigarettes per day with significantly fewer self-identifying as smokers and experiencing significantly reduced COPD symptoms. CONCLUSION An interdisciplinary, team-based approach was effective for improving the health of COPD patients in an Appalachian academic primary care practice.

Abstract
Background One of the most important factors in the pathogenesis of COPD (chronic obstructive pulmonary disease) is oxidative stress. GGT (gamma-glutamyltransferase) has been regarded as a novel marker of oxidative stress over the last few years. This study aimed to compare the serum levels of GGT during stable and acute exacerbations of COPD at a single center. Material/Methods The research included 117 patients with AECOPD (acute exacerbation of chronic obstructive pulmonary disease), 107 patients with stable COPD, and 112 control subjects. Serum GGT, spirometry function, and other clinical parameters (anthropometric and biochemical measurements) were evaluated and compared among the subjects. Results Serum GGT was elevated in patients with stable COPD in comparison to the control subjects. Its level was inversely related to lung function. It was also significantly higher in AECOPD patients compared to stable COPD patients. We also found that a GGT level of 21.2 IU/L displays a reliable diagnostic prediction of COPD and that a GGT level of 26.5 IU/L can be applied to predict the exacerbation of COPD. Conclusions Our research demonstrates that serum GGT level is inversely associated with pulmonary function and may serve as a biomarker during the progression of COPD. The monitoring of GGT values can be applied to evaluating COPD and its exacerbation risk.

[PMID: 32589690 PMCID: PMC7319351 DOI: 10.1371/journal.pone.0235429] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 06/15/2020] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND A cost analysis of implementation of interventions informs budgeting and economic evaluations. OBJECTIVE To estimate the cost of implementing the integrated chronic disease management (ICDM) model in primary healthcare (PHC) clinics in South Africa. METHODS Cost data from the provider's perspective were collected in 2019 from four PHC clinics with comparable patient caseloads (except for one). We estimated the costs of implementing the ICDM model current activities for three (facility reorganization, clinical supportive management and assisted self-management) components and additional costs of implementing with enhanced fidelity. Costs were estimated based on budget reviews, interviews with management teams, and other published data. The standard of care activities such as medication were not included in the costing. One-way sensitivity analyses were carried out for key parameters by varying patient caseloads, required infrastructure and staff. Annual ICDM model implementation costs per PHC clinic and per patient per visit are presented in 2019 US dollars. RESULTS The overall mean annual cost of implementing the ICDM model was $148 446.00 (SD: $65 125.00) per clinic. Current ICDM model activities cost accounted for 84% ($124 345.00) of the annual mean cost, while additional costs for higher fidelity were 16% ($24 102.00). The mean cost per patient per visit was $6.00 (SD:$0.77); $4.94 (SD:0.70) for current cost and $1.06 (SD:0.33) for additional cost to enhance ICDM model fidelity. For the additional cost, 49% was for facility reorganization, 31% for adherence clubs and 20% for training of nursing staff. In the sensitivity analyses, the major cost drivers were the proportion of effort of assisted self-management staff and the number of patients with chronic diseases receiving care at the clinic. CONCLUSION Minimal additional cost are required to implement the ICDM model with higher fidelity. Further research on the cost-effectiveness of the ICDM model in middle-income countries is required.
