Abstract
BACKGROUND Economic burden studies can provide insights into the drivers leading to increasing healthcare costs. It can also provide a more holistic view of how diseases impact the welfare of patients and their families. Having concrete estimates of the economic burden across multiple diseases can help policymakers determine which diseases are economically more burdensome. This study aimed to review and summarise comprehensively economic burden studies across multiple diseases in the Nordic countries between 2000 and 2020. METHODS According to the 2020 PRISMA statement, a systematic literature review was conducted in PubMed, CINAHL, Academic Search Premier and Global Health databases using key terms related to the economic burden of any disease in Denmark, Finland, Greenland, Iceland, Norway and Sweden. Grey literature was also reviewed. RESULTS A total of 10,050 potential titles and abstracts were identified and screened, and 254 full-text papers that met the inclusion criteria were evaluated by two independent reviewers. Of these, 119 articles were included in a qualitative synthesis. Twenty-nine had clearly defined comparison groups, thus able to attribute the costs to the disease. Large variations concerning methodology and cost components were noted. Across diseases, the economic burden ranged from EUR 1668 per patient annually for chronic obstructive pulmonary disease to EUR 93,041 for multiple sclerosis. However, estimates varied widely, even within each disease. CONCLUSIONS Our review highlights the need for more comparable economic burden studies. Future studies should focus on applying robust methodology and homogeneous cost-reporting methods to inform policymakers about which diseases are economically more burdensome.

The Association between Medical Utilization and Chronic Obstructive Pulmonary Disease Severity: A Comparison of the 2007 and 2011 Guideline Staging Systems. Healthcare (Basel) 2022; 10:healthcare10040721. [PMID: 35455899 PMCID: PMC9024555 DOI: 10.3390/healthcare10040721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2022] [Revised: 04/10/2022] [Accepted: 04/11/2022] [Indexed: 12/10/2022] Open
Abstract
(1) Background: This study aimed to investigate the associations between the Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging systems, medical costs, and mortality among patients with chronic obstructive lung disease (COPD). Predictions of the effectiveness of the two versions of the staging systems were also compared. (2) Purpose: this study investigated the associations between the Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging systems, medical costs, and mortality among patients with COPD. Predicting effectiveness between the two versions of the staging systems was also compared. (3) Procedure: This study used a secondary clinical database of a medical center in central Taiwan to examine records between 2011 and 2017. A total of 613 patients with COPD were identified. The independent variables comprised the COPD GOLD Guideline staging of the 2007 and 2011 versions, demographic characteristics, health status, and physician seniority. The dependent variables included total medical cost, average length of hospital stay, and mortality. The statistical methods included binomial logistic regression and the general linear model (GLM). (4) Discussion: The total medical cost during the observation period for patients with COPD averaged TWD 292,455.6. The average length of hospital stay was 9.7 days. The mortality rate was 9.6%, compared with that of patients in Grade 1 of the 2007 version; patients in Grade 4 of the 2007 version had significantly higher odds of death (OR = 4.07, p = 0.02). The accuracy of mortality prediction for both the 2007 and 2011 versions of the staging was equal, at 90.4%. The adjusted GLM analysis revealed that patients in Group D of the 2011 version had a significantly longer length of hospital stay than those in Group A of the 2011 version (p = 0.04). No difference between the 2007 and 2011 versions was found regarding the total medical cost. Complications were significantly associated with the total medical cost and average length of hospital stay. (5) Conclusions: The COPD staging 2011 version was associated with an average length of hospital stay, whereas the COPD staging 2007 version was related to mortality risk. Therefore, the 2011 version can estimate the length of hospital stay. However, in predicting prognosis and mortality, the 2007 version is recommended.

Abstract
OBJECTIVE To assess the impact of interventions for improving the management of chronic obstructive pulmonary disease (COPD), specifically increased use of pulmonary rehabilitation (PR) on patient outcomes and cost-benefit analysis. DATA SOURCES We used the national Hospital Episode Statistics (HES) datasets in England, local data and experts from the hospital setting, National Prices and National Tariffs, reports and the literature around the effectiveness of PR programs. STUDY DESIGN The COPD pathway was modeled using discrete event simulation (DES) to capture the patient pathway to an adequate level of detail as well as randomness in the real world. DES was further enhanced by the integration of a health economic model to calculate the net benefit and cost of treating COPD patients based on key sets of interventions. DATA COLLECTION/EXTRACTION METHODS A total of 150 input parameters and 75 distributions were established to power the model using the HES dataset, outpatient activity data from the hospital and community services, and the literature. PRINCIPAL FINDINGS The simulation model showed that increasing referral to PR (by 10%, 20%, or 30%) would be cost-effective (with a benefit-cost ratio of 5.81, 5.95, and 5.91, respectively) by having a positive impact on patient outcomes and operational metrics. Number of deaths, admissions, and bed days decreased (ie, by 3.56 patients, 4.90 admissions, and 137.31 bed days for a 30% increase in PR referrals) as well as quality of life increased (ie, by 5.53 QALY among 1540 patients for the 30% increase). CONCLUSIONS No operational model, either statistical or simulation, has previously been developed to capture the COPD patient pathway within a hospital setting. To date, no model has investigated the impact of PR on COPD services, such as operations, key performance, patient outcomes, and cost-benefit analysis. The study will support policies around extending availability of PR as a major intervention.

Abstract
Purpose Chronic obstructive pulmonary disease (COPD) exacerbations can negatively impact disease severity, progression, mortality and lead to hospitalizations. We aimed to develop a model that predicts a patient's risk of hospitalization due to severe exacerbations (defined as COPD-related hospitalizations) of COPD, using Swedish patient level data. Patients and Methods Patient level data for 7823 Swedish patients with COPD was collected from electronic medical records (EMRs) and national registries covering healthcare contacts, diagnoses, prescriptions, lab tests, hospitalizations and socioeconomic factors between 2000 and 2013. Models were created using machine-learning methods to predict risk of imminent exacerbation causing patient hospitalization due to COPD within the next 10 days. Exacerbations occurring within this period were considered as one event. Model performance was assessed using the Area under the Precision-Recall Curve (AUPRC). To compare performance with previous similar studies, the Area Under Receiver Operating Curve (AUROC) was also reported. The model with the highest mean cross validation AUPRC was selected as the final model and was in a final step trained on the entire training dataset. Results The most important factors for predicting severe exacerbations were exacerbations in the previous six months and in whole history, number of COPD-related healthcare contacts and comorbidity burden. Validation on test data yielded an AUROC of 0.86 and AUPRC of 0.08, which was high in comparison to previously published attempts to predict COPD exacerbation. Conclusion Our work suggests that clinically available information on patient history collected via automated retrieval from EMRs and national registries or directly during patient consultation can form the basis for future clinical tools to predict risk of severe COPD exacerbations.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a major health problem and an economic burden globally. There is growing interest in how electronic health (eHealth) can be used to provide efficient health care. Telemonitoring, where the patient's health-related data is transmitted to a health care provider, can be used to detect early signs of exacerbations. A successful implementation of telemonitoring systems into clinical practice requires in-depth knowledge of the users' preferences. OBJECTIVE The aim of this study was to explore perceptions of the use of a home telemonitoring system among patients with COPD. METHODS Semistructured individual interviews were carried out with 8 women and 5 men who were participants in a project aimed at developing and evaluating a telemonitoring system. The web-based telemonitoring system measured pulmonary function, subjective symptoms, and oxygen saturation. Participants were interviewed after having used the system for 2-4 months. Interview transcripts were analyzed with qualitative content analysis. RESULTS The analysis resulted in the theme A transition toward increased control and security and four categories: using with (in)security, affecting technical concern or confidence, providing easy access to health care, and increasing control over the disease. The participants reported various perceptions of using the telemonitoring system. They expressed initial feelings of insecurity, both in terms of operating the system and in terms of their disease. However, the practical management of the telemonitoring system became easier with time; the participants gradually gained confidence and improved their self-management. New technology was perceived as an important complement to existing health care, but the importance of maintaining a human contact in real life or through the telemonitoring system was emphasized. CONCLUSIONS This study captured a transition among the participants from being insecure and experiencing technical concerns to acquiring technical confidence and improving disease management. Telemonitoring can be a valuable complement to health care, leading to increased self-knowledge, a sense of security, and improved self-management. Suggestions to improve the further development and implementation of telemonitoring systems include better patient education and the involvement of end users in the technical development process. Additional research is needed, particularly in the design of user-friendly systems, as well as in developing tools to predict which patients are most likely to find the equipment useful, as this may result in increased empowerment, improved quality of life, reduced costs, and a contribution to equity in health.

Abstract
OBJECTIVES To find the economic burden of COPD and to identify the key cost drivers in the management of COPD patients across different European countries. BACKGROUND COPD is a major cause of mortality and morbidity and is associated with considerable economic burden on the individual and society. It limits the daily activities and working ability of the patients. METHODOLOGY We conducted a systematic search of PUBMED, SCIENCE DIRECT, Cochrane CENTRAL, SCOPUS, Google Scholar and SAGE Premier Databases to find scientific research articles evaluating the cost of COPD management from patient and societal perspective. RESULTS Estimated per patient per year direct cost in Norway, Denmark, Germany, Italy, Sweden, Greece, Belgium, and Serbia was €10,701, €9580, €7847, €7448, €7045, €2896, €1963, and €2047, respectively. Annual per patient cost of work productivity loss was highest in Germany as €5735 and lowest in Greece as €998. It was estimated as €4824, €2033 and €1298 in Bulgaria, Denmark and Sweden, respectively. Several factors found associated with increasing cost of COPD management that include but not limited to late diagnosis, severity of disease, frequency of exacerbation, hospital readmissions, non-adherence to the therapy and exposure to COPD risk factors. CONCLUSION Minimizing the COPD exacerbations and controlling the worsening of symptoms may potentially reduce the cost of COPD management at any stage.

Abstract
BACKGROUND Observational studies indicate that beta-blockers are associated with a reduced risk of exacerbation and mortality in patients with chronic obstructive pulmonary disease (COPD) even without overt cardiovascular disease, but data from randomized controlled trials (RCT) are lacking. The aim of this RCT is to investigate whether beta-blocker therapy in patients with COPD without diagnosed cardiovascular disease is associated with a decreased 1-year risk of the composite endpoint of death, exacerbations, or cardiovascular events. METHODS The Beta-blockeRs tO patieNts with CHronIc Obstructive puLmonary diseasE (BRONCHIOLE) study is an open-label, multicentre, prospective RCT. A total of 1700 patients with COPD will be randomly assigned to either standard COPD care and metoprolol at a target dose of 100 mg per day or to standard COPD care only. The primary endpoint is a composite of death, COPD exacerbations, and cardiovascular events. Major exclusion criteria are ischemic heart disease, left-sided heart failure, cerebrovascular disease, critical limb ischemia, and atrial fibrillation/flutter. Study visits are an inclusion visit, a metoprolol titration visit at 1 month, follow-up by telephone at 6 months, and a final study visit after 1 year. Outcome data are obtained from medical history and record review during study visits, as well as from national registries. DISCUSSION BRONCHIOLE is a pragmatic randomized trial addressing the potential of beta-blockers in patients with COPD. The trial is expected to provide relevant clinical data on the efficacy of this treatment on patient-related outcomes in patients with COPD. TRIAL REGISTRATION ClinicalTrials.gov, ID: NCT03566667.

Abstract
Background: Lack of information about economic burden of COPD is a major cause of lack of attention to this chronic condition from governments and policymakers. Objective: To find the economic burden of COPD in Asia, USA and Europe, and to identify the key cost driving factors in management of COPD patients. Methodology: Relevant studies assessing the cost of COPD from patient perspective or societal perspective were retrieved by thoroughly searching PUBMED, SCIENCE DIRECT, GOOGLE SCHOLAR, SCOPUS, and SAGE Premier Databases. Results: In the USA annual per patient direct medical cost and hospitalization cost were reported as $10,367 and $6852, respectively. In Asia annual per patient direct medical cost in Iran, Korea and Singapore was reported as $1544, $3077, and $2335, respectively. However, annual per patient hospitalization cost in Iran, Korea, Singapore, India, China, and Turkey was reported as $865, $1371, $1868, $296, $1477 and $1031, respectively. In Europe annual per patient direct medical cost was reported as $11,787, $10,552, $8644, $8203, $7760, $3190, $1889, $2162, and $2254 in Norway, Denmark, Germany, Italy, Sweden, Greece, Spain, Belgium, and Serbia, respectively. Conclusion: Limiting the disease to early stage and preventing exacerbations may reduce the cost of management of COPD.

Abstract
Background Evidence on the economic impact of chronic obstructive pulmonary disease (COPD) for third-party payers and society based on large real world datasets are still scarce. Therefore, the aim of this study was to estimate the economic impact of COPD severity and its comorbidities, stratified by GOLD grade, on direct and indirect costs for an unselected population enrolled in the structured German Disease Management Program (DMP) for COPD. Methods All individuals enrolled in the DMP COPD were included in the analysis. Patients were only excluded if they were not insured or not enrolled in the DMP COPD the complete year before the last DMP documentation (at physician visit), had a missing forced expiratory volume in 1 s (FEV1) measurement or other missing values in covariates. The final dataset included 39,307 patients in GOLD grade 1 to 4. We used multiple generalized linear models to analyze the association of COPD severity with direct and indirect costs, while adjusting for sex, age, income, smoking status, body mass index, and comorbidities. Results More severe COPD was significantly associated with higher healthcare utilization, work absence, and premature retirement. Adjusted annual costs for GOLD grade 1 to 4 amounted to €3809 [€3691–€3935], €4284 [€4176–€4394], €5548 [€5328–€5774], and €8309 [€7583-9065] for direct costs, and €11,784 [€11,257–€12,318], €12,985 [€12,531-13,443], €15,805 [€15,034–€16,584], and €19,402 [€17,853–€21,017] for indirect costs. Comorbidities had significant additional effects on direct and indirect costs with factors ranging from 1.19 (arthritis) to 1.51 (myocardial infarction) in direct and from 1.16 (myocardial infarction) to 1.27 (cancer) in indirect costs. Conclusion The findings indicate that more severe GOLD grades in an unselected COPD population enrolled in a structured DMP are associated with tremendous additional direct and indirect costs, with comorbidities significantly increase costs. In direct cost category hospitalization and in indirect cost category premature retirement were the main cost driver. From a societal perspective prevention and interventions focusing on disease control, and slowing down disease progression and strengthening the ability to work would be beneficial in order to realize cost savings in COPD.

Abstract
INTRODUCTION The use of adequate self-management strategies for people with chronic obstructive pulmonary disease (COPD) may increase the level of physical activity (PA), improve health-related quality of life (HRQoL) and reduce healthcare use. Whether web-based support in addition to prompts (email and SMS) could be used to promote self-management strategies to facilitate behaviour change in people with COPD is not clear. This clinical trial aims to generate evidence on the effect of a web-based solution, the COPD Web, in a cohort of people with COPD in a primary healthcare context. METHODS AND ANALYSIS The overall design is a pragmatic randomised controlled trial with preassessments and postassessments (3 and 12 months) and an implementation and user experience evaluation. People with a diagnosis of COPD, treated in primary healthcare will be eligible for the study. A total of 144 participants will be enrolled through advertisment or by healthcare professionals at included primary healthcare units and, after fulfilled baseline assessment, randomised to either control or intervention group. All participants will receive usual care, a pedometer and a leaflet about the importance of PA. Participants in the intervention will, in addition, get access to the COPD Web, an interactive self-managed website that aims to support people with COPD in self-management strategies. They will also continuously get support from prompts with a focus on behaviour change.The effect on participants' PA, dyspnoea, COPD-related symptoms, HRQoL and health economics will be assessed using accelerometer and questionnaires. To identify enablers and barriers for the use of web-based support to change behaviour, semistructured interviews will be conducted in a subgroup of participants at the 3 months follow-up. ETHICS AND DISSEMINATION Ethical approval has been received from the Regional Ethical Review Board in Umeå, Sweden. Dnr 2018-274 and dnr 2019-05572. Findings will be presented at conferences, submitted for publication in peer-reviewed journals and presented to the involved healthcare professionals, participants and patient organisations.

Abstract
Chronic nonmalignant pulmonary diseases impose a heavy burden on patients, generate health-care costs, and contribute to poor health-related quality of life. It has been found that a wide range of factors negatively affects quality of life, but the role of acceptance of illness needs to be further investigated. The aim of the study was to evaluate the relationship between acceptance of illness and quality of life in patients with chronic nonmalignant pulmonary diseases. The study encompassed 200 patients of the mean age 58 ± 16 years who were mainly diagnosed with asthma (n = 72; 36%), COPD (n = 52; 26%), and obstructive sleep apnea (n = 38; 19%). The patients answered the Acceptance of Illness Scale (AIS) and the St. George's Respiratory Questionnaire (SGRQ). Sociodemographical and clinical data were collected. The level of acceptance of illness significantly associated with each of the SGRQ domains. The greater the acceptance of illness, the lowest was the SGRQ score. The mean total score of SGRQ was 44.6 ± 24.9 and that of AIS was 26.1 ± 8.2. Higher AIS scores significantly associated with lower SGRQ scores, i.e., with better quality of life (p < 0.001 for each domain). We conclude that in patients with chronic nonmalignant pulmonary diseases, acceptance of illness plays an important role and is closely related to the general level of quality of life. Interventions aimed at improving acceptance of illness may be considered to improve quality of life.

Abstract
Background In light of overall increasing healthcare expenditures, it is mandatory to study determinants of future costs in chronic diseases. This study reports the first longitudinal results on healthcare utilization and associated costs from the German chronic obstructive pulmonary disease (COPD) cohort COSYCONET. Material and methods Based on self-reported data of 1904 patients with COPD who attended the baseline and 18-month follow-up visits, direct costs were calculated for the 12 months preceding both examinations. Direct costs at follow-up were regressed on baseline disease severity and other co-variables to identify determinants of future costs. Change score models were developed to identify predictors of cost increases over 18 months. As possible predictors, models included GOLD grade, age, sex, education, smoking status, body mass index, comorbidity, years since COPD diagnosis, presence of symptoms, and exacerbation history. Results Inflation-adjusted mean annual direct costs increased by 5% (n.s., €6,739 to €7,091) between the two visits. Annual future costs were significantly higher in baseline GOLD grades 2, 3, and 4 (factors 1.24, 95%-confidence interval [1.07–1.43], 1.27 [1.09–1.48], 1.57 [1.27–1.93]). A history of moderate or severe exacerbations within 12 months, a comorbidity count >3, and the presence of dyspnea and underweight were significant predictors of cost increase (estimates ranging between + €887 and + €3,679, all p<0.05). Conclusions Higher GOLD grade, comorbidity burden, dyspnea and moderate or severe exacerbations were determinants of elevated future costs and cost increases in COPD. In addition we identified underweight as independent risk factor for an increase in direct healthcare costs over time.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterised by recurring exacerbations. We estimated the costs of healthcare resources for COPD management funded by the Italian National Healthcare Service (INHS) for one year. METHODS We examined the demographic, clinical, and economic variables at enrolment and follow-up visits (at 6 and 12 months) of COPD patients participating in the SAT study and referred to 20 Italian pulmonary centres with different institutional characteristics. Costs were expressed in Euro (€) 2018. A random effects log-linear panel regression model was performed to predict the average cost per patient. RESULTS Most of the centres were public institutions (90%; public university hospital: 30%). The total average cost of COPD was €2647.38/patient and ICS/LABA/LAMA therapy contributed the most (€1541.45). The average cost was €6206.19/patient for severe COPD (+139.67% vs the cost/patient with mild or moderate COPD). The regression model showed that, others things being equal, increases in the predicted average logged cost per patient were due to liquid oxygen therapy (+468.31%), three COPD exacerbations during the follow-up (+254.54%), and ICS/LABA or ICS/LABA/LAMA associated therapy (+59.26%). Moreover, a 1.19% increment was observed for each additional score of the CAT questionnaire. Conversely, a 36.52% reduction in the predicted average logged cost was reported for hospitals managed by local healthcare authorities. CONCLUSIONS The health econometric approach is innovative in the management of COPD patients in Italy. The results of the random effects log-linear panel data regression model may help clinicians estimate INHS costs when managing COPD patients. Clinicaltrials.gov ID# NCT02689492.

Abstract
Purpose: Assess the clinical and economic consequences associated with an early versus late diagnosis in patients with COPD. Patients and methods: In a retrospective, observational cohort study, electronic medical record data (2000-2014) were collected from Swedish primary care patients with COPD. COPD indicators (pneumonia, other respiratory diseases, oral corticosteroids, antibiotics for respiratory infections, prescribed drugs for respiratory symptoms, lung function measurement) registered prior to diagnosis were applied to categorize patients into those receiving early (2 or less indicators) or late diagnosis (3 or more indicators registered >90 days preceding a COPD diagnosis). Outcome measures included annual rate of and time to first exacerbation, mortality risk, prevalence of comorbidities and health care utilization. Results: More patients with late diagnosis (n=8827) than with early diagnosis (n=3870) had a recent comorbid diagnosis of asthma (22.0% vs 3.9%; P<0.0001). Compared with early diagnosis, patients with late diagnosis had a higher exacerbation rate (hazard ratio [HR] 1.89, 95% confidence interval [CI]: 1.83-1.96; P<0.0001) and shorter time to first exacerbation (HR 1.61, 95% CI: 1.54-1.69; P<0.0001). Mortality was not different between groups overall but higher for late versus early diagnosis, after excluding patients with past asthma diagnosis (HR 1.10, 95% CI: 1.02-1.18; P=0.0095). Late diagnosis was also associated with higher direct costs than early diagnosis. Conclusion: Late COPD diagnosis is associated with higher exacerbation rate and increased comorbidities and costs compared with early diagnosis. The study highlights the need for accurate diagnosis of COPD in primary care in order to reduce exacerbations and the economic burden of COPD.

Abstract
PURPOSE OF REVIEW Chronic obstructive pulmonary disease (COPD) affects over 12 million adults in the United States and is the third leading cause of 30-day readmissions. COPD is costly with almost $50 billion in direct costs annually. Total COPD costs can be up to double the identified direct costs because of comorbid disease and numerous indirect costs such as absenteeism. Acute exacerbations of COPD (AECOPD) are responsible for up to 70% of COPD-related healthcare costs; hospital readmissions alone account for over $15 billion annually. In this review, we aim to describe insights about the economic impact of COPD readmissions based on articles published over the last 18 months. RECENT FINDINGS Interventions aimed at reducing readmission, particularly those using interdisciplinary teams with bundled care interventions, were uniformly successful at improving the quality of care provided and demonstrating improved process measures. However, success at reducing readmissions and cost savings based on these interventions varied across the studies. SUMMARY The literature to date points to factors and conditions that may place patients at higher risk of readmissions and may lead to higher costs. Interventions aimed at reducing readmissions after index admissions for AECOPD have demonstrated variable results. Most interventions did not reflect cost-based analyses.

Abstract
Background Several studies have assessed the impact of chronic obstructive pulmonary disease (COPD) on work ability and work productivity; however, this relationship is poorly understood. Aims To undertake a systematic review to assess the effects of COPD on employment, absenteeism and presenteeism. Methods A comprehensive search using CINAHL, Embase, MEDLINE and the Cochrane Library was conducted to include epidemiological studies from 1937 to August 2017. One reviewer screened all citations. Shortlisted full-text articles were independently assessed by a second reviewer. Data were extracted by one reviewer with a random sample of papers (45%) checked by a second reviewer. Results Forty-four studies were included; the majority of evidence was from cross-sectional studies, and some cohort studies. COPD patients had lower employment rates than those without COPD. Among those in work, most studies showed patients with COPD took more time off work than those without and reported poorer work performance (presenteeism), although evidence for this association was weaker. The influence of disease severity on these outcomes was unclear; however, it appeared that increasing severity of airflow obstruction was associated with reduced likelihood of being employed. A number of methodological limitations were found among the evidence, including the lack of adjustment for important confounders. Conclusions Future studies are required which assess the impact of COPD on presenteeism using validated presenteeism instruments and consistent reporting methods. Robust studies are now needed to identify modifiable factors associated with these poorer working outcomes to inform future interventions aimed at improving work productivity among those with COPD.

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) is a highly prevalent chronic disease characterised by persistent respiratory symptoms. A focus of COPD interventional studies is directed towards prevention of exacerbations leading to hospital readmissions. Telehealth as a method of remote patient monitoring and care delivery may be implemented to reduce hospital readmissions and improve self-management of disease. Prior reviews have not systematically assessed the efficacies of various telehealth functionalities in patients with COPD at different stages of disease severity. We aim to evaluate which COPD telehealth interventions, classified by their functionalities, are most effective in improving patient with COPD management measured by both clinical and resource utilisation outcomes. METHODS AND ANALYSIS We will conduct a systematic review which will include randomised controlled trials comparing the efficacy of telehealth interventions versus standard care in patients with COPD with confirmed disease severity based on forced expiratory volume(%) levels. An electronic search strategy will be used to identify trials published since 2000 in MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, CINHAL. Telehealth is described as remote monitoring and delivery of care where patient data/clinical information is routinely or continuously collected and/or processed, presented to the patient and transferred to a clinical care institution for feedback, triage and intervention by a clinical specialist. Two authors will independently screen articles for inclusion, assess risk of bias and extract data. We will merge studies into a meta-analysis if the interventions, technologies, participants and underlying clinical questions are homogeneous enough. We will use a random-effects model, as we expect some heterogeneity between interventions. In cases where a meta-analysis is not possible, we will synthesise findings narratively. We will assess the quality of the evidence for the main outcomes using GRADE. ETHICS AND DISSEMINATION Research ethics approval is not required. The findings will be disseminated through publication in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42018083671.

Abstract
BACKGROUND Exacerbations of chronic obstructive pulmonary disease (COPD) are an important measure of disease severity in terms of impaired disease progression, increased recovery time, healthcare resource utilization, overall morbidity and mortality. We aimed to quantify exacerbation and healthcare resource utilization rates among COPD patients in Sweden with respect to baseline treatments, exacerbation history, and comorbidities. METHODS Patients with a COPD or chronic bronchitis (CB) diagnosis in secondary care at age of ≥40 years on 1.7.2009 were identified and followed until 1.7.2010 or death. Severe exacerbations were defined as hospitalizations due to respiratory disease, and healthcare resource utilization was measured by all-cause hospitalizations and secondary care visits. Poisson regression was used adjusting for age, gender, time since COPD/CB diagnosis, and Charlson comorbidity index. RESULTS In 88,548 patients (54% females, mean age 72 years), previous respiratory hospitalizations and current high use of COPD medication (double or triple therapy) predicted an 8.3-fold increase in severe exacerbation rates and 1.8-fold increase in healthcare resource utilization rates in the following year, compared to patients without combination treatment and/or history of severe exacerbations. CONCLUSIONS COPD/CB patients with history of severe exacerbations and high use of COPD medication experienced a significantly increased rate of severe exacerbations and healthcare resource utilization during the one-year follow-up.

Abstract
Introduction Chronic obstructive pulmonary disease (COPD) places a major burden on health care systems and has substantial economic effects; however, the cost of stable disease in Greece has never been thoroughly explored. The objective of the study was to estimate the annual COPD patient cost during the maintenance phase and explore the relationships between the cost and disease severity. Methods Data were collected from 245 COPD patients (male: 231, mean age: 69.5±8.8 years) who visited the outpatient unit of University Hospital of Larissa in 2014 and 2015. Patients were classified according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, and the patients’ direct cost during the maintenance phase was calculated. Results Eleven percent of COPD patients were stage I, 48.2% were stage II, 29% were stage III, and 11.8% were stage IV. According to the GOLD groups, 23.3% of patients were grade A, 15.5% were grade B, 22.9% were grade C, and 38.4% were grade D. The mean annual direct cost for stable disease was estimated at €1,034.55 per patient, of which €222.94 corresponded to out-of-pocket payments. The annual cost ranged from €408.23 to €2,041.89 depending on GOLD stages (I–IV) and from €550.01 to €1,480.00 depending on GOLD groups (A–D). The key cost driver was pharmaceutical treatment, which reflected almost 71% of the total expenses for the management of stable disease. The mean annual per-patient cost was two to three times higher for those with advanced disease (stages III–IV) compared to those with stages I–II disease, and it doubled for “high-risk” patients (groups C–D) compared to “low-risk” patients (groups A–B). Conclusion The cost of COPD during the maintenance phase is remarkable, with the key cost driver found to be pharmaceutical treatment and social insurance funds the key payer for treating COPD patients in Greece. The cost of stable disease is proportional to the severity of COPD, and it is doubled in patients who belong to high-risk groups.

Abstract
Background We assessed direct and indirect costs associated with COPD in Sweden and examined how these costs vary across time, age, and disease stage in a cohort of patients with COPD and matched controls in a real-world, primary care (PC) setting. Patients and methods Data from electronic medical records linked to the mandatory national health registers were collected for COPD patients and a matched reference population in 52 PC centers from 2000 to 2014. Direct health care costs (drug, outpatient or inpatient, PC, both COPD related and not COPD related) and indirect health care costs (loss of income, absenteeism, loss of productivity) were assessed. Results A total of 17,479 patients with COPD and 84,514 reference controls were analyzed. During 2013, direct costs were considerably higher among the COPD patient population (€13,179) versus the reference population (€2,716), largely due to hospital nights unrelated to COPD. Direct costs increased with increasing disease severity and increasing age and were driven by higher respiratory drug costs and non-COPD-related hospital nights. Indirect costs (~€28,000 per patient) were the largest economic burden in COPD patients of working age during 2013. Conclusion As non-COPD-related hospital nights represent the largest direct cost, management of comorbidities in COPD would offer clinical benefits and relieve the financial burden of disease.

Indacaterol/glycopyrronium is cost-effective compared to salmeterol/fluticasone in COPD: FLAME-based modelling in a Swedish population. Respir Res 2017; 18:206. [PMID: 29228950 PMCID: PMC5725803 DOI: 10.1186/s12931-017-0688-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2017] [Accepted: 11/23/2017] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND This study assessed the cost-effectiveness of indacaterol/glycopyrronium (IND/GLY) versus salmeterol/fluticasone (SFC) in chronic obstructive pulmonary disease (COPD) patients with moderate to very severe airflow limitation and ≥1 exacerbation in the preceding year. METHODS A previously published and validated patient-level simulation model was adapted using clinical data from the FLAME trial and real-world cost data from the ARCTIC study. Costs (total monetary costs comprising drug, maintenance, exacerbation, and pneumonia costs) and health outcomes (life-years (LYs), quality-adjusted life-years (QALYs)) were projected over various time horizons (1, 5, 10 years, and lifetime) from the Swedish payer's perspective and were discounted at 3% annually. Uncertainty in model input values was studied through one-way and probabilistic sensitivity analyses. Subgroup analyses were also performed. RESULTS IND/GLY was associated with lower costs and better outcomes compared with SFC over all the analysed time horizons. Use of IND/GLY resulted in additional 0.192 LYs and 0.134 QALYs with cost savings of €1211 compared with SFC over lifetime. The net monetary benefit (NMB) was estimated to be €8560 based on a willingness-to-pay threshold of €55,000/QALY. The NMB was higher in the following subgroups: severe (GOLD 3), high risk and more symptoms (GOLD D), females, and current smokers. CONCLUSION IND/GLY is a cost-effective treatment compared with SFC in COPD patients with mMRC dyspnea grade ≥ 2, moderate to very severe airflow limitation, and ≥1 exacerbation in the preceding year.

Abstract
Background Although patients with COPD often have various comorbidities and symptoms, limited data are available on the contribution of these aspects to health care costs. This study analyzes the association of frequent comorbidities and common symptoms with the annual direct and indirect costs of patients with COPD. Methods Self-reported information on 33 potential comorbidities and symptoms (dyspnea, cough, and sputum) of 2,139 participants from the baseline examination of the German COPD cohort COSYCONET was used. Direct and indirect costs were calculated based on self-reported health care utilization, work absence, and retirement. The association of comorbidities, symptoms, and COPD stage with annual direct/indirect costs was assessed by generalized linear regression models. Additional models analyzed possible interactions between COPD stage, the number of comorbidities, and dyspnea. Results Unadjusted mean annual direct costs were €7,263 per patient. Other than COPD stage, a high level of dyspnea showed the strongest driving effect on direct costs (+33%). Among the comorbidities, osteoporosis (+38%), psychiatric disorders (+36%), heart disease (+25%), cancer (+24%), and sleep apnea (+21%) were associated with the largest increase in direct costs (p<0.01). A sub-additive interaction between advanced COPD stage and a high number of comorbidities reduced the independent cost-driving effects of these factors. For indirect costs, besides dyspnea (+34%), only psychiatric disorders (+32%) and age (+62% per 10 years) were identified as significant drivers of costs (p<0.04). In the subsequent interaction analysis, a high number of comorbidities was found to be a more crucial factor for increased indirect costs than single comorbidities. Conclusion Detailed knowledge about comorbidities in COPD is useful not only for clinical purposes but also to identify relevant cost factors and their interactions and to establish a ranking of major cost drivers. This could help in focusing therapeutic efforts on both clinically and economically important comorbidities in COPD.

Abstract
Objective The aim of this study was to investigate whether echo intensity of the rectus femoris when measured using ultrasound can distinguish muscles affected by COPD compared with healthy non-COPD affected muscles and whether the severity of ultrasonic abnormalities was associated with health-related quality of life (HRQoL). Methods Echo intensity, areas of the rectus femoris, and the thickness of quadriceps muscles were measured using ultrasound in 50 COPD outpatients and 21 age-matched non-COPD controls. The results of the 8-Item Short-Form Health Survey and the functional assessment of chronic illness therapy fatigue scales were used to evaluate HRQoL. Results There was a significantly higher echo intensity of the rectus femoris in all stages of COPD patients than in age-matched non-COPD subjects; the quadriceps muscle thickness and cross-sectional area of the rectus femoris significantly decreased in COPD GOLD III–IV only. Furthermore, in our stable COPD patients, echo intensity of the rectus femoris was associated with HRQoL independently. Conclusion Quantitative ultrasound distinguishes healthy muscles from those affected by COPD grade I–IV, and quality and quantity of muscles are associated with HRQoL and forced expiratory volume in 1 second. Ultrasonic echo intensity of the rectus femoris may be a useful instrument for assessing disease severity and monitoring the changes of skeletal muscle resulting from disease progression or clinical intervention in patients with COPD.

Abstract
We aimed to examine associations between chronic airflow obstruction (CAO) and unemployment across the world. Cross-sectional data from 26 sites in the Burden of Obstructive Lung Disease (BOLD) study were used to analyse effects of CAO on unemployment. Odds ratios for unemployment in subjects aged 40–65 years were estimated using a multilevel mixed-effects generalised linear model with study site as random effect. Site-by-site heterogeneity was assessed using individual participant data meta-analyses. Out of 18 710 participants, 11.3% had CAO. The ratio of unemployed subjects with CAO divided by subjects without CAO showed large site discrepancies, although these were no longer significant after adjusting for age, sex, smoking and education. The site-adjusted odds ratio (95% CI) for unemployment was 1.79 (1.41–2.27) for CAO cases, decreasing to 1.43 (1.14–1.79) after adjusting for sociodemographic factors, comorbidities and forced vital capacity. Of other covariates that were associated with unemployment, age and education were important risk factors in high-income sites (4.02 (3.53–4.57) and 3.86 (2.80–5.30), respectively), while female sex was important in low- to middle-income sites (3.23 (2.66–3.91)). In the global BOLD study, CAO was associated with increased levels of unemployment, even after adjusting for sociodemographic factors, comorbidities and lung function. Chronic airflow obstruction increases risk of unemployment, and is a burden to welfare systems worldwidehttp://ow.ly/cxzv30cQ17A

Abstract
Cigarette smoking is a primary risk factor for chronic obstructive pulmonary disease (COPD), as it damages epithelial cells through a variety of mechanisms. Sulforaphane (SFN) is an antioxidant agent, which exerts protective effects against cell damage by activating the nuclear factor erythroid 2 like 2 (NFE2L2; Nrf2). The present study was undertaken to investigate the effects and underlying mechanisms of SFN in preventing cigarette smoke extract (CSE)‑induced oxidative damage to RLE‑6TN rat lung epithelial cells. MTT assay was used to determine the cytotoxicity of SFN and CSE. The effect of SFN and CSE on cell cycle progression, apoptosis and intracellular reactive oxygen species (ROS) levels were analyzed using flow cytometry. Reverse transcription‑quantitative polymerase chain reaction and western blotting were used to quantify mRNA and protein expression levels of Nrf2 respectively. SFN protected RLE‑6TN cells from oxidative damage, potentially via increasing Nrf2 expression and reducing ROS levels. In addition, SFN attenuated G1 phase cell cycle arrest and abrogated apoptosis. Therefore, SFN protected alveolar epithelial cells against CSE‑induced oxidative injury by upregulating Nrf2 expression. The results of the present study may provide theoretical support for the clinical use of SFN in patients with COPD.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is a public health problem. Interprofessional collaboration and health promotion interventions such as exercise training, education, and behaviour change are cost effective, have a good effect on health status, and are recommended in COPD treatment guidelines. There is a gap between the guidelines and the healthcare available to people with COPD. The aim of this study was to increase the understanding of what shapes the provision of primary care services to people with COPD and what healthcare is offered to them from the perspective of healthcare professionals and managers. Methods The study was conducted in primary care in a Swedish county council during January to June 2015. A qualitatively driven mixed methods design was applied. Qualitative and quantitative findings were merged into a joint analysis. Interviews for the qualitative component were performed with healthcare professionals (n = 14) from two primary care centres and analysed with qualitative content analysis. Two questionnaires were used for the quantitative component; one was answered by senior managers or COPD nurses at primary care centres (n = 26) in the county council and the other was answered by healthcare professionals (n = 18) at two primary care centres. The questionnaire data were analysed with descriptive statistics. Results The analysis gave rise to the overarching theme building COPD care on shaky ground. This represents professionals driven to build a supportive COPD care on ‘shaky’ organisational ground in a fragmented and non-compliant healthcare organisation. The shaky ground is further represented by uninformed patients with a complex disease, which is surrounded with shame. The professionals are autonomous and pragmatic, used to taking responsibility for their work, and with limited involvement of the management. They wish to provide high quality COPD care with interprofessional collaboration, but they lack competence and are hindered by inadequate routines and lack of resources. Conclusions There is a gap between COPD treatment guidelines and the healthcare that is provided in primary care. To facilitate implementation of the guidelines several actions are needed, such as further training for professionals, additional resources, and improved organisational structure for interprofessional collaboration and patient education.

Respir Med 2017; 129:179-188.

Abstract
BACKGROUND Fixed-dose combinations of inhaled corticosteroids and long-acting β2 agonists are commonly used for the treatment of asthma and COPD. However, the most frequently prescribed dry powder inhaler delivering this medicine - Symbicort® (budesonide and formoterol, BF) Turbuhaler® - is associated with poor inhalation technique, which can lead to poor disease control and high disease management costs. A recent study showed that patients make fewer inhaler errors when using the novel DuoResp® (BF) Spiromax® inhaler, compared with BF Turbuhaler®. Therefore switching patients from BF Turbuhaler® to BF Spiromax® could improve inhalation technique, and potentially lead to better disease control and healthcare cost savings. METHODS A model was developed to estimate the budget impact of reducing poor inhalation technique by switching asthma and COPD patients from BF Turbuhaler® to BF Spiromax® over three years in Germany, Italy, Sweden and the UK. The model estimated changes to the number, and associated cost, of unscheduled healthcare events. The model considered two scenarios: in Scenario 1, all patients were immediately switched from BF Turbuhaler® to BF Spiromax®; in Scenario 2, 4%, 8% and 12% of patients were switched in years 1, 2 and 3 of the model, respectively. RESULTS In Scenario 1, per patient cost savings amounted to €60.10, €49.67, €94.14 and €38.20 in Germany, Italy, Sweden and the UK, respectively. Total cost savings in each country were €100.86 million, €19.42 million, €36.65 million and €15.44 million over three years, respectively, with an estimated 597,754, 151,480, 228,986 and 122,368 healthcare events avoided. In Scenario 2, cost savings totalled €8.07 million, €1.55 million, €2.93 million and €1.23 million over three years, respectively, with 47,850, 12,118, 18,319, and 9789 healthcare events avoided. Savings per patient were €4.81, €3.97, €7.53 and €3.06. CONCLUSIONS We demonstrated that reductions in poor inhalation technique by switching patients from BF Turbuhaler® to BF Spiromax® are likely to improve patients' disease control and generate considerable cost savings through healthcare events avoided.

Abstract
BACKGROUND While the impact of COPD in Western-Europe is known, data from Eastern-Europe is scarce. This study aimed to evaluate clinical characteristics, treatment patterns, and the socio-economic burden of COPD in Eastern-Europe, taking Bulgaria as a reference case. METHODS A representative sample of Bulgarian patients with COPD was randomly chosen by pulmonologists, based on the following inclusion criteria: COPD diagnosis with at least 1 year of living with COPD, ≥40 years of age, and use of COPD medication. Patient characteristics, treatment, quality-of-life, healthcare resource use, and costs were systematically assessed. RESULTS A total of 426 COPD patients were enrolled. Approximately 69% were male, 40% had occupational risk factors, 45% had severe and 11% had very severe COPD. Mean CAT scores were 13.80 (GOLD A), 21.80 (GOLD B), 17.35 (GOLD C), and 26.70 (GOLD D). Annual per-patient costs of healthcare utilization were €579. Yearly pharmacotherapy costs were €693. Indirect costs (reduced and lost work productivity) outnumbered direct costs three times. CONCLUSIONS Bulgaria has relatively high percentages of (very) severe COPD patients, resulting in considerable socio-economic burden. High smoking rates, occupational risk factors, air pollution, and a differential health system may be related to this finding. Eastern-European COPD strategies should focus on prevention, risk-factor awareness, and early detection.

Abstract
PURPOSE The purpose of this study was to identify subtypes in patients with mild-to-moderate airflow limitation and to appreciate their clinical and socioeconomic implications. METHODS Subjects who were aged ≥20 years and had forced expiratory volume in 1 second (FEV1) ≥60% predicted and FEV1/forced vital capacity <0.7 were selected from the fourth Korea National Health and Nutrition Examination Survey (KNHANES) in 2007-2012. The data were merged to the National Health Insurance reimbursement database during the same period. k-Means clustering was performed to explore subtypes. For clustering analysis, six key input variables - age, body mass index (BMI), FEV1% predicted, the presence or absence of self-reported wheezing, smoking status, and pack-years of smoking - were selected. RESULTS Among a total of 2,140 subjects, five groups were identified through k-means clustering, namely putative "near-normal (n=232)," "asthmatic (n=392)," "chronic obstructive pulmonary disease (COPD) (n=37)," "asthmatic-overlap (n=893)," and "COPD-overlap (n=586)" subtypes. Near-normal group showed the oldest mean age (72±7 years) and highest FEV1 (102%±8% predicted), and asthmatic group was the youngest (46±9 years). COPD and COPD-overlap groups were male predominant and all current or ex-smokers. While asthmatic group had the lowest prescription rate despite the highest proportion of self-reported wheezing, COPD, asthmatic-overlap, and COPD-overlap groups showed high prescription rate of respiratory medicine. Although COPD group formed only 1.7% of total subjects, they showed the highest mean medical cost and health care utilization, comprising 5.3% of the total medical cost. When calculating a ratio of total medical expense to household income, the mean ratio was highest in the COPD group. CONCLUSION Clinical and epidemiological heterogeneities of subjects with mild-to-moderate airflow limitation and a different level of health care utilization by each subtype are shown. Identification of a subtype with high health care demand could be a priority for effective utilization of limited resources.

Abstract
BACKGROUND Guidelines have provided positive recommendations for pulmonary rehabilitation after exacerbations of chronic obstructive pulmonary disease (COPD), but recent studies indicate that postexacerbation rehabilitation may not always be effective in patients with unstable COPD. OBJECTIVES To assess effects of pulmonary rehabilitation after COPD exacerbations on hospital admissions (primary outcome) and other patient-important outcomes (mortality, health-related quality of life (HRQL) and exercise capacity). SEARCH METHODS We identified studies through searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PEDro (Physiotherapy Evidence Database) and the Cochrane Airways Review Group Register of Trials. Searches were current as of 20 October 2015, and handsearches were run up to 5 April 2016. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing pulmonary rehabilitation of any duration after exacerbation of COPD versus conventional care. Pulmonary rehabilitation programmes had to include at least physical exercise (endurance or strength exercise, or both). We did not apply a criterion for the minimum number of exercise sessions a rehabilitation programme had to offer to be included in the review. Control groups received conventional community care without rehabilitation. DATA COLLECTION AND ANALYSIS We expected substantial heterogeneity across trials in terms of how extensive rehabilitation programmes were (i.e. in terms of number of completed exercise sessions; type, intensity and supervision of exercise training; and patient education), duration of follow-up (< 3 months vs ≥ 3 months) and risk of bias (generation of random sequence, concealment of random allocation and blinding); therefore, we performed subgroup analyses that were defined before we carried them out. We used standard methods expected by Cochrane in preparing this update, and we used GRADE for assessing the quality of evidence. MAIN RESULTS For this update, we added 11 studies and included a total of 20 studies (1477 participants). Rehabilitation programmes showed great diversity in terms of exercise training (number of completed exercise sessions; type, intensity and supervision), patient education (from none to extensive self-management programmes) and how they were organised (within one setting, e.g. pulmonary rehabilitation, to across several settings, e.g. hospital, outpatient centre and home). In eight studies, participants completed extensive pulmonary rehabilitation, and in 12 studies, participants completed pulmonary rehabilitation ranging from not extensive to moderately extensive.Eight studies involving 810 participants contributed data on hospital readmissions. Moderate-quality evidence indicates that pulmonary rehabilitation reduced hospital readmissions (pooled odds ratio (OR) 0.44, 95% confidence interval (CI) 0.21 to 0.91), but results were heterogenous (I2 = 77%). Extensiveness of rehabilitation programmes and risk of bias may offer an explanation for the heterogeneity, but subgroup analyses were not statistically significant (P values for subgroup effects were between 0.07 and 0.11). Six studies including 670 participants contributed data on mortality. The quality of evidence was low, and the meta-analysis did not show a statistically significant effect of rehabilitation on mortality (pooled OR 0.68, 95% CI 0.28 to 1.67). Again, results were heterogenous (I2 = 59%). Subgroup analyses showed statistically significant differences in subgroup effects between trials with more and less extensive rehabilitation programmes and between trials at low and high risk for bias, indicating possible explanations for the heterogeneity. Hospital readmissions and mortality studies newly included in this update showed, on average, significantly smaller effects of rehabilitation than were seen in earlier studies.High-quality evidence suggests that pulmonary rehabilitation after an exacerbation improves health-related quality of life. The eight studies that used St George's Respiratory Questionnaire (SGRQ) reported a statistically significant effect on SGRQ total score, which was above the minimal important difference (MID) of four points (mean difference (MD) -7.80, 95% CI -12.12 to -3.47; I2 = 64%). Investigators also noted statistically significant and important effects (greater than MID) for the impact and activities domains of the SGRQ. Effects were not statistically significant for the SGRQ symptoms domain. Again, all of these analyses showed heterogeneity, but most studies showed positive effects of pulmonary rehabilitation, some studies showed large effects and others smaller but statistically significant effects. Trials at high risk of bias because of lack of concealment of random allocation showed statistically significantly larger effects on the SGRQ than trials at low risk of bias. High-quality evidence shows that six-minute walk distance (6MWD) improved, on average, by 62 meters (95% CI 38 to 86; I2 = 87%). Heterogeneity was driven particularly by differences between studies showing very large effects and studies showing smaller but statistically significant effects. For both health-related quality of life and exercise capacity, studies newly included in this update showed, on average, smaller effects of rehabilitation than were seen in earlier studies, but the overall results of this review have not changed to an important extent compared with results reported in the earlier version of this review.Five studies involving 278 participants explicitly recorded adverse events, four studies reported no adverse events during rehabilitation programmes and one study reported one serious event. AUTHORS' CONCLUSIONS Overall, evidence of high quality shows moderate to large effects of rehabilitation on health-related quality of life and exercise capacity in patients with COPD after an exacerbation. Some recent studies showed no benefit of rehabilitation on hospital readmissions and mortality and introduced heterogeneity as compared with the last update of this review. Such heterogeneity of effects on hospital readmissions and mortality may be explained to some extent by the extensiveness of rehabilitation programmes and by the methodological quality of the included studies. Future researchers must investigate how the extent of rehabilitation programmes in terms of exercise sessions, self-management education and other components affects the outcomes, and how the organisation of such programmes within specific healthcare systems determines their effects after COPD exacerbations on hospital readmissions and mortality.

Abstract
Pulmonary rehabilitation (PR) brings benefits to patients with chronic obstructive pulmonary disease (COPD). Negative pressure ventilation (NPV) increases ventilation and decreases hyperinflation as well as breathing work in COPD. We evaluated the long-term effects of a hospital-based PR program coupled with NPV support in patients with COPD on clinical outcomes.One hundred twenty-nine patients with COPD were followed up for more than 5 years, with the NPV group (n = 63) receiving the support of NPV (20-30 cm H2O delivery pressure for 60 min) and unsupervised home exercise program of 20 to 30 min daily walk, while the control group (n = 6) only received unsupervised home exercise program. Pulmonary function tests and 6 min walk tests (6MWT) were performed every 3 to 6 months. Emergency room (ER) visits and hospitalization with medical costs were recorded.A significant time-by-group interaction in the yearly decline of forced expiratory volume in 1 s in the control group analyzed by mixed-model repeated-measure analysis was found (P = 0.048). The 6MWT distance of the NPV group was significantly increased during the first 4 years, with the interaction of time and group (P = 0.003), the time alone (P = 0.014), and the quadratic time (P < 0.001) being significant between the 2 groups. ER exacerbations and hospitalizations decreased by 66% (P < 0.0001) and 54% (P < 0.0001) in the NPV group, respectively. Patients on PR program coupled with NPV had a significant reduction of annual medical costs (P = 0.022).Our hospital-based multidisciplinary PR coupled with NPV reduced yearly decline of lung function, exacerbations, and hospitalization rates, and improved walking distance and medical costs in patients with COPD during a 5-year observation.

Abstract
Purpose The purpose of this study was to define the prevalence of undiagnosed airflow obstruction (AO) among subjects with a history of smoking but no previous diagnosis of chronic lung disease. The finding of AO likely represents diagnosis of chronic obstructive pulmonary disease. Patients People aged ≥30 years with a history of smoking who attended public outpatient clinics for primary care services were included in this study. Methods A cross-sectional survey in five clinics in Hong Kong using the Breathlessness, Cough, and Sputum Scale, the Lung Function Questionnaire, and office spirometry was conducted. Results In total, 731 subjects (response rate =97.9%) completed the questionnaires and spirometry tests. Most of the subjects were men (92.5%) in the older age group (mean age =62.2 years; standard deviation =11.7). Of the 731 subjects, 107 had AO, giving a prevalence of 14.6% (95% confidence interval =12.1–17.2); 45 subjects with AO underwent a postbronchodilator test. By classifying the severity of chronic obstructive pulmonary disease using the Global Initiative for Chronic Obstructive Lung Disease, 27 (60%) were considered to be in mild category and 18 (40%) in moderate category. None of them belonged to the severe or very severe category. The total score of Lung Function Questionnaire showed that majority of the subjects with AO also had chronic cough, wheezing attack, or breathlessness, although most did not show any acute respiratory symptoms in accordance with the Breathlessness, Cough, and Sputum Scale. Diagnosis of AO was positively associated with the number of years of smoking (odds ratio =1.044, P=0.035) and being normal or underweight (odds ratio =1.605, P=0.046). It was negatively associated with a history of hypertension (odds ratio =0.491, P=0.003). Conclusion One-seventh of smokers have undiagnosed AO. Spirometry screening of smokers should be considered in order to diagnose AO at an early stage, with an emphasis on smoking cessation.

Abstract
Objectives The objectives of this study were to estimate the impact of recruitment source and outcome definition on the incidence of acute exacerbations of COPD (AECOPD) and explore possible predictors of AECOPD. Patients and methods During a 1-year follow-up, we performed a baseline visit and four telephone interviews of 81 COPD patients and 132 controls recruited from a population-based survey and 205 hospital-recruited COPD patients. Both a definition based on health care utilization and a symptom-based definition of AECOPD were applied. For multivariate analyses, we chose a negative binomial regression model. Results COPD patients from the population- and hospital-based samples experienced on average 0.4 utilization-defined and 2.9 symptom-defined versus 1.0 and 5.9 annual exacerbations, respectively. The incidence rate ratios for utilization-defined AECOPD were 2.45 (95% CI 1.22–4.95), 3.43 (95% CI 1.59–7.38), and 5.67 (95% CI 2.58–12.48) with Global Initiative on Obstructive Lung Disease spirometric stages II, III, and IV, respectively. The corresponding incidence rate ratios for the symptom-based definition were 3.08 (95% CI 1.96–4.84), 3.45 (95% CI 1.92–6.18), and 4.00 (95% CI 2.09–7.66). Maintenance therapy (regular long-acting muscarinic antagonists, long-acting beta-2 agonists, inhaled corticosteroids, or theophylline) also increased the risk of AECOPD with both exacerbation definitions (incidence rate ratios 1.65 and 1.73, respectively). The risk of AECOPD was 59%–78% higher in the hospital sample than in the population sample. Conclusion If externally valid conclusions are to be made regarding incidence and predictors of AECOPD, studies should be based on general population samples or adjustments should be made on account of a likely higher incidence in other samples. Likewise, the effect of different AECOPD definitions should be taken into consideration.

Abstract
Objective To evaluate the impact of lung function, measured as forced expiratory volume in 1 second (FEV1) % predicted, on health care resource utilization and costs among patients with COPD in a real-world US managed-care population. Methods This observational retrospective cohort study utilized administrative claim data augmented with medical record data. The study population consisted of patients with one or more medical claims for pre- and postbronchodilator spirometry during the intake period (July 1, 2012 to June 30, 2013). The index date was the date of the earliest medical claim for pre- and postbronchodilator spirometry. Spirometry results were abstracted from patients’ medical records. Patients were divided into two groups (low FEV1% predicted [,50%] and high FEV1% predicted [≥50%]) based on the 2014 Global Initiative for Chronic Obstructive Lung Disease report. Health care resource utilization and costs were based on the prevalence and number of discrete encounters during the 12-month postindex follow-up period. Costs were adjusted to 2014 US dollars. Results A total of 754 patients were included (n=297 low FEV1% predicted group, n=457 high FEV1% predicted group). COPD exacerbations were more prevalent in the low FEV1% predicted group compared with the high group during the 12-month pre- (52.5% vs 39.6%) and postindex periods (49.8% vs 36.8%). Mean (standard deviation) follow-up all-cause and COPD-related costs were $27,380 ($38,199) and $15,873 ($29,609) for patients in the low FEV1% predicted group, and $22,075 ($28,108) and $10,174 ($18,521) for patients in the high group. In the multivariable analyses, patients in the low FEV1% predicted group were more likely to have COPD exacerbations and tended to have higher COPD-related costs when compared with patients in the high group. Conclusion Real-world data demonstrate that patients with COPD who have low FEV1% predicted levels use more COPD medications, have more COPD exacerbations, and incur higher COPD-related health care costs than those with high FEV1% predicted levels.

Abstract
BACKGROUND Asthma and chronic obstructive pulmonary disease (COPD) are common chronic inflammatory respiratory diseases, which impose a substantial burden on healthcare systems and society. Fixed-dose combinations (FDCs) of inhaled corticosteroids (ICS) and long-acting β2 agonists (LABA), often administered using dry powder inhalers (DPIs), are frequently prescribed to control persistent asthma and COPD. Use of DPIs has been associated with poor inhalation technique, which can lead to increased healthcare resource use and costs. METHODS A model was developed to estimate the healthcare resource use and costs associated with asthma and COPD management in people using commonly prescribed DPIs (budesonide + formoterol Turbuhaler(®) or fluticasone + salmeterol Accuhaler(®)) over 1 year in Spain, Sweden and the United Kingdom (UK). The model considered direct costs (inhaler acquisition costs and scheduled and unscheduled healthcare costs), indirect costs (productive days lost), and estimated the contribution of poor inhalation technique to the burden of illness. RESULTS The direct cost burden of managing asthma and COPD for people using budesonide + formoterol Turbuhaler(®) or fluticasone + salmeterol Accuhaler(®) in 2015 was estimated at €813 million, €560 million, and €774 million for Spain, Sweden and the UK, respectively. Poor inhalation technique comprised 2.2-7.7 % of direct costs, totalling €105 million across the three countries. When lost productivity costs were included, total expenditure increased to €1.4 billion, €1.7 billion and €3.3 billion in Spain, Sweden and the UK, respectively, with €782 million attributable to poor inhalation technique across the three countries. Sensitivity analyses showed that the model results were most sensitive to changes in the proportion of patients prescribed ICS and LABA FDCs, and least sensitive to differences in the number of antimicrobials and oral corticosteroids prescribed. CONCLUSIONS The cost of managing asthma and COPD using commonly prescribed DPIs is considerable. A substantial, and avoidable, contributor to this burden is poor inhalation technique. Measures that can improve inhalation technique with current DPIs, such as easier-to-use inhalers or better patient training, could offer benefits to patients and healthcare providers through improving disease outcomes and lowering costs.

Abstract
OBJECTIVES Tiotropium (TIO), Spiriva® Handihaler®, is a well-established bronchodilator, LAMA (long acting muscarinic antagonist), for the treatment of moderate to very severe chronic obstructive pulmonary disease (COPD). Clinical evidence from the SPARK trial suggests that TIO is superior to glycopyrronium (GLY), Seebri® Breezhaler®, in terms of severe exacerbations. This modeling study assessed the cost-effectiveness of TIO versus GLY for Canada (CAN), Spain (ESP), Sweden (SWE), and the UK, making use of this new clinical evidence. METHODS A Markov cohort model, with moderate to very severe (Global Initiative for Chronic Obstructive Lung Disease II-IV) COPD patients, was populated with efficacy data from the Understanding Potential Long-term Impacts on Function with Tiotropium (UPLIFT) and SPARK trials as well as costs, utilities, and epidemiological data relevant for each country. Treatment efficacy was modeled as improvements in lung function, quality-adjusted life years (QALYs), and as a lowering of the risk of exacerbations (rate of exacerbations). Risks of exacerbations differed between cohorts based on data from SPARK. Health and cost outcomes were simulated over an approximate lifetime horizon, starting from the age of 65 years. Robustness of results was validated in deterministic sensitivity analyses. RESULTS Over the lifetime horizon, patients treated with TIO accumulated -623 (CAN), 1,066 (ESP), 1,137 (SWE), and -169 (UK), respectively, in incremental costs (€2014). TIO generated better health outcomes compared to GLY in all countries, 0.21 (CAN), 0.25 (ESP), 0.23 (SWE), and 0.23 (UK) in incremental QALYs. The cost per QALY gained was found to be €4,281 and €1,137 for ESP and SWE, respectively, while TIO was found to be cost saving in CAN and the UK. The results were mainly driven by the relative risk of severe exacerbations found in SPARK (GLY/TIO relative risk: 1.43, 95% confidence interval: 1.05-1.97, P=0.025). CONCLUSION The results from this study show that TIO is a cost-effective treatment compared to GLY in moderate to very severe COPD. The cost per QALY is well below the existing implicit and explicit willingness-to-pay thresholds.

Abstract
BACKGROUND Even though respiratory symptoms are common in the adult population, there is limited research describing their impact on everyday life and association with health care consumption. AIM The main objective of this population-based study was to estimate and compare the prevalence of respiratory symptoms among adults in Finland, Estonia, and Sweden in relation to health care consumption and to identify factors influencing health care consumption. A secondary aim was to assess to which extent the presence of respiratory symptoms affect everyday life. METHOD In the population-based FinEsS studies consisting of random samples of subjects aged 20 to 69 years from Finland (n=1,337), Estonia (n=1,346), and Sweden (n=1,953), data on demographics, respiratory health, and health care consumption were collected by structured interviews. Prevalence was compared and multiple logistic regression analyses were performed. RESULTS Respiratory symptoms were significantly more common in Finland (66.0%) and Estonia (65.2%) than in Sweden (54.1%). Among subjects with respiratory symptoms, the proportion reporting outpatient care during the past year was fairly similar in the three countries, while specialist consultations were more common in Finland (19.1%), and hospitalisations more common in Estonia (15.0%). Finnish and Estonian residency, female sex, and BMI>25 increased the risk for outpatient care consumption. Wheeze and attacks of shortness of breath in the past 12 months, recurrent sputum production, and cough were associated with an increased risk for health care consumption. Increasing number of respiratory symptoms increased the risk for consuming health care. A larger proportion of subjects in Estonia and Sweden experienced their everyday life being affected by respiratory symptoms compared with subjects in Finland. CONCLUSION Respiratory symptoms are common in Finland, Estonia, and Sweden and contribute to a negative impact on everyday life as well as increased health care consumption. The observed differences in health care consumption between countries are probably related to national differences in health care structure.

Abstract
BACKGROUND Co-morbidities are common in COPD; however, there is a lack of population-based studies evaluating the health economic impact of co-morbid diseases for subjects with COPD. The main objective of this study was to estimate annual direct health-care costs, divided into costs due to non-respiratory and respiratory conditions, comparing subjects with and without COPD. METHODS Subjects with and without COPD derived from population-based cohorts in northern Sweden have been invited to annual examinations involving spirometry and structured interviews since 2005. This paper is based on data from 1472 subjects examined in 2006. COPD classification was based on spirometry. RESULTS Mean annual costs for both respiratory and non-respiratory conditions were significantly higher for subjects with COPD than non-COPD subjects, in total USD 2139 vs. USD 1276 (p = 0.026), and COPD remained significantly associated with higher costs also after adjustment for common confounders as age, smoking habits, BMI and sex. The mean total cost increased with COPD disease severity and was higher for all severity stages (GOLD) than for non-COPD subjects. Hospitalization due to non-respiratory diseases was the main cost driver in COPD, after adjustment for common confounders amounting to about 46% (unadjusted 62%) of the total COPD-costs. CONCLUSIONS Costs were higher for COPD than non-COPD. In COPD, costs for co-morbid conditions were higher than those for respiratory conditions, and hospitalization due to co-morbid conditions was the main cost driver also when adjusted for common confounders.

Abstract
BACKGROUND The burden of COPD in terms of mortality, morbidity, costs and prevalence has increased worldwide. Recent results on prevalence in Western Europe are conflicting. In Sweden smoking prevalence has steadily decreased over the past 30 years. AIM The aim was to study changes in prevalence and risk factor patterns of COPD in the same area and within the same age-span 15 years apart. MATERIAL AND METHODS Two population-based cross-sectional samples in ages 23-72 years participating at examinations in 1994 and 2009, respectively, were compared in terms of COPD prevalence, severity and risk factor patterns. Two different definitions of COPD were used; FEV1/FVC < LLN and FEV1/FVC < 0.7. The severity of COPD was assessed by FEV1, both as % of predicted and in relation to the LLN. RESULTS The prevalence of COPD decreased significantly from 9.5% to 6.3% (p = 0.030) according to the FEV1/FVC < LLN criterion, while the decrease based on the FEV1/FVC < 0.7 criterion from 10.5% to 8.5% was non-significant. The prevalence of moderate to severe COPD decreased substantially and significantly, and the risk factor pattern was altered in 2009 when, beside age and smoking, also socio-economic status based on occupation was significantly associated with COPD. CONCLUSIONS Changes in both prevalence and risk factor patterns of COPD were observed between surveys. Following a continuing decrease in smoking habits over several decades, a decrease in the prevalence of moderate to severe COPD was observed from 1994 to 2009 in northern Sweden.

Abstract
INTRODUCTION COPD is the third leading cause of death in the world. Utilizing care bundles during acute COPD exacerbations results in fewer complications and lower costs. Our aim was to construct a COPD exacerbation care bundle and evaluate the effects on patient care. METHODS We conducted a prospective analysis of 44 patients admitted with a COPD exacerbation to a single tertiary care facility. Primary outcomes included length of stay, readmission rates, and hospital costs. Secondary outcomes included patient education, pulmonologist follow-up, and timeliness of medication administration. Two cohorts were analyzed: those treated with an electronic COPD care bundle (cases; N=22) versus those treated without the care bundle (controls; N=22). RESULTS Mean length of stay (51.2 vs 101.1 hours in controls; P-value =0.001), 30-day readmission rates (9.1% vs 54.4% in controls; P-value =0.001), and 60-day readmission rates (22.7% vs 77% in controls; P-value =0.0003) decreased in the care bundle group. Ninety-day hospital costs had a significant difference in the care bundle group (US$7,652 vs US$19,954 in controls; P-value =0.044). Secondary outcomes included a 100% rate of COPD inhaler teaching (vs 27.3% in controls; P-value <0.001), 59.1% rate of pulmonologist follow-up after discharge (vs 18.2% in controls; P-value =0.005), and a mean reduction in time to steroid administration (7.0 hours; P-value =0.015) seen in the care bundle cases. CONCLUSION Our significant findings coupled with the recent success of standardized algorithms in managing COPD exacerbations stress the importance of enforcing clinical guidelines that can enhance patient care. We demonstrated improved care for COPD exacerbation patients during hospitalizations, thereby decreasing morbidity and the financial burden hospitals face in regard to this increasingly prevalent disease.

Abstract
BACKGROUND Respiratory diseases exert a substantial burden on society, with newer drugs increasingly adding to the burden. Economic models are often used, but seldom reviewed. PURPOSE To summarize economic models used in economic analyses of drugs treating moderate-to-severe/very severe asthma or chronic obstructive pulmonary disease (COPD). METHODS This study searched Medline and Embase from inception to the end of February 2015 for cost-effectiveness/utility analyses that examined at least one drug against placebo, another drug, or other standard therapy in asthma or COPD. Two reviewers independently searched and extracted data with differences adjudicated via consensus discussion. Data extracted included model used and its qualities, validation methods, treatments compared, disease severity, analytic perspective, time horizon, data collection (pro- or retrospective), input rates and sources, costs and sources, planned sensitivity analyses, criteria for cost-effectiveness, reported outcomes, and sponsor. RESULTS This study analyzed 53 articles; 14 (25%) on asthma and 39 (75%) COPD. Markov models were commonly used for both asthma and COPD-related economic evaluations. Relatively few studies validated their model. For asthma-related studies, 10 examined inhaled corticosteroids and nine studied omalizumab. Placebo or standard therapy was the comparison in 11 studies and active drugs in the remainder. CONCLUSIONS Few studies include validation of their models. Furthermore, controversy concerning some results was uncovered in this study, which needs to be avoided in the future.

Abstract
OBJECTIVES The objective of this study was to compare the cost effectiveness of once-daily Seebri Breezhaler(®) (glycopyrronium bromide) 50 µg with Spiriva(®) (tiotropium bromide) 18 µg in the maintenance treatment of chronic obstructive pulmonary disease (COPD) in the Swedish setting. METHODS A previously published COPD Markov model accounting for disease progression and treatment discontinuation was used. Disease progression included the annual decline in forced expiratory volume in the first second (FEV1) and occurrence of any exacerbations. Efficacy in the model consisted of FEV1 improvement between baseline and 12 weeks and the annual risk ratio of having an exacerbation compared to placebo. These clinical efficacy inputs were derived from a 1-year head-to-head trial comparing glycopyrronium 50 µg to tiotropium 18 µg. Utility values and cost estimates were obtained from the literature. The base-case analysis was performed for a 3-year time horizon. Cost and effects were discounted with 3% in accordance to Swedish guidelines. Uncertainty was assessed by one-way and probabilistic sensitivity analyses. RESULTS Glycopyrronium was found to be less costly and more effective than tiotropium in moderate to severe COPD patients with cost savings of 5197 Swedish kronor (€570, US$725) per patient over a 3-year time horizon. The probabilistic sensitivity analysis indicated that over 99% of the iterations produced dominant results for glycopyrronium. CONCLUSION Glycopyrronium bromide 50 µg once daily can be considered a cost effective alternative to tiotropium bromide 18 µg once daily in the maintenance treatment of COPD patients in Sweden.

Abstract
Cardiopulmonary diseases are major causes of death worldwide, but currently recommended strategies for diagnosis and prevention may be outdated because of recent changes in risk factor patterns. The Swedish CArdioPulmonarybioImage Study (SCAPIS) combines the use of new imaging technologies, advances in large-scale 'omics' and epidemiological analyses to extensively characterize a Swedish cohort of 30 000 men and women aged between 50 and 64 years. The information obtained will be used to improve risk prediction of cardiopulmonary diseases and optimize the ability to study disease mechanisms. A comprehensive pilot study in 1111 individuals, which was completed in 2012, demonstrated the feasibility and financial and ethical consequences of SCAPIS. Recruitment to the national, multicentre study has recently started.

Eklund O, Afzal F, Borgström F. Cost-effectiveness of tiotropium versus usual care and glycopyrronium in the treatment of chronic obstructive pulmonary disease in Sweden. COST EFFECTIVENESS AND RESOURCE ALLOCATION 2015; 13:13. [PMID: 26288574 PMCID: PMC4539698 DOI: 10.1186/s12962-015-0040-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2014] [Accepted: 08/10/2015] [Indexed: 11/10/2022] Open
Abstract
Background Tiotropium (TIO) is a well-established bronchodilator, LAMA (long-acting anticholinergic), for the treatment of moderate to very severe chronic obstructive pulmonary disease (COPD). Clinical evidence suggests that tiotropium is superior to usual non-LAMA care (UC) but may also have benefits compared to other LAMAs in preventing and limiting the effects of severe exacerbations. The primary objective of this study was to undertake a cost-effectiveness analysis of adding tiotropium to usual care versus usual care alone. A secondary objective was to assess the cost-effectiveness of tiotropium compared to glycopyrronium (GLY), another LAMA. The study was conducted with a Swedish setting in mind. Methods A Markov cohort model, incorporating the effects of exacerbations, was populated with efficacy data from the UPLIFT and SPARK trials and epidemiological data relevant for a Swedish patient population. Treatment efficacy of tiotropium was modelled as a lowering of the risk of exacerbations and as a slow-down of overall disease progression. The model followed patients over their remaining life-time. Results The base case analysis showed that patients treated with tiotropium gained 0.07 quality-adjusted life years (QALYs) compared to usual care alone at an incremental cost of SEK 15,041, resulting in a cost per QALY gained of SEK 224,850. Compared to glycopyrronium the QALY gained was estimated to 0.23 QALYs in favour of tiotropium at an incremental cost of SEK 2423, yielding a cost per QALY gained of SEK 10,456. The results were mainly driven by differences in the risk of severe exacerbations. Conclusion At the current implicit willingness-to-pay (WTP) per QALY threshold in Sweden, the results from this study indicate that tiotropium is a highly cost-effective intervention when added to usual non-LAMA care in the treatment of moderate to very severe COPD in Sweden. In addition, tiotropium is a highly cost-effective intervention when compared to glycopyrronium monotherapy.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a major burden for the health care system, but the exact costs are difficult to estimate and there are insufficient data available on past and future time trends of COPD-related costs. AIMS The aim of the study was to calculate COPD-related costs in Finland during the years 1996-2006 and estimate future costs for the years 2007-2030. METHODS COPD-related direct and indirect costs in the public health care sector of the whole of Finland during the years 1996-2006 were retrieved from national registers. In addition, we made a mathematical prediction model on COPD costs for the years 2007-2030 on the basis of population projection and changes in smoking habits. RESULTS The total annual COPD-related costs amounted to about 100-110 million Euros in 1996-2006, with no obvious change, but there was a slight decrease in direct costs and an increase in indirect costs during these years. The estimation model predicted a 60% increase up to 166 million Euros in COPD-related annual costs by the year 2030. This is caused almost entirely by an increase in direct health care costs that reflect the predicted ageing of the Finnish population, as older age is a significant factor that increases the need for hospitalisation. CONCLUSIONS The total annual COPD-related costs in Finland have been stable during the years 1996-2006, but if management strategies are not changed a significant increase in direct costs is expected by the year 2030 due to ageing of the population.

Abstract
BACKGROUND COPD remains a leading cause of morbidity and mortality. The objectives of this study were to estimate (1) national US COPD-attributable annual medical costs by payer (direct) and absenteeism (indirect) in 2010 and projected medical costs through 2020 and (2) state-specific COPD-attributable medical and absenteeism costs in 2010. METHODS We used the 2006-2010 Medical Expenditure Panel Survey, the 2004 National Nursing Home Survey, and 2010 Centers for Medicare and Medicaid Services data to generate cost estimates and 2010 census data to project medical costs through 2020. RESULTS In 2010, total national medical costs attributable to COPD and its sequelae were estimated at $32.1 billion, and total absenteeism costs were $3.9 billion, for a total burden of COPD-attributable costs of $36 billion. An estimated 16.4 million days of work were lost because of COPD. Of the medical costs, 18% was paid for by private insurance, 51% by Medicare, and 25% by Medicaid. National medical costs are projected to increase from $32.1 billion in 2010 to $49.0 billion in 2020. Total state-specific costs in 2010 ranged from $49.1 million in Wyoming to $2.8 billion in California: medical costs ranged from $42.5 million in Alaska to $2.5 billion in Florida and absenteeism costs ranged from $8.4 million in Wyoming to $434.0 million in California. CONCLUSIONS Costs attributable to COPD and its sequelae are substantial and are projected to increase through 2020. Evidence-based interventions that prevent tobacco use and reduce the clinical complications of COPD may result in potential decreased COPD-attributable costs.

Abstract
Objectives We aimed to estimate incremental productivity losses (sick leave and disability) of spirometry-defined chronic obstructive pulmonary disease (COPD) in a population-based sample and in hospital-recruited patients with COPD. Furthermore, we examined predictors of productivity losses by multivariate analyses. Methods We performed four quarterly telephone interviews of 53 and 107 population-based patients with COPD and controls, as well as 102 hospital-recruited patients with COPD below retirement age. Information was gathered regarding annual productivity loss, exacerbations of respiratory symptoms and comorbidities. Incremental productivity losses were estimated by multivariate quantile median regression according to the human capital approach, adjusting for sex, age, smoking habits, education and lung function. Main effect variables were COPD/control status, number of comorbidities and exacerbations of respiratory symptoms. Results Altogether 55%, 87% and 31% of population-based COPD cases, controls and hospital patients, respectively, had a paid job at baseline. The annual incremental productivity losses were 5.8 (95% CI 1.4 to 10.1) and 330.6 (95% CI 327.8 to 333.3) days, comparing population-recruited and hospital-recruited patients with COPD to controls, respectively. There were significantly higher productivity losses associated with female sex and less education. Additional adjustments for comorbidities, exacerbations and FEV1% predicted explained all productivity losses in the population-based sample, as well as nearly 40% of the productivity losses in hospital-recruited patients. Conclusions Annual incremental productivity losses were more than 50 times higher in hospital-recruited patients with COPD than that of population-recruited patients with COPD. To ensure a precise estimation of societal burden, studies on patients with COPD should be population-based.

Respir Med 2014; 108:1786-93. [PMID: 25307414 DOI: 10.1016/j.rmed.2014.09.015] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2014] [Revised: 09/22/2014] [Accepted: 09/23/2014] [Indexed: 11/17/2022]
Abstract
BACKGROUND Indacaterol/glycopyrronium (IND/GLY) is a once-daily inhaled fixed-dose combination of indacaterol (IND), a long-acting β2-adrenergic agonist (LABA), and glycopyrronium (GLY), a long-acting muscarinic antagonist (LAMA) for use as maintenance treatment to relieve symptoms of chronic obstructive pulmonary disease (COPD) in adults. OBJECTIVE To determine the economic benefits of IND/GLY compared with the free combination of indacaterol and glycopyrronium (IND + GLY), and with the fixed-dose combination of salmeterol/fluticasone (SFC), in a moderate-to-severe COPD population with low-exacerbation risk. The model-based analysis extrapolated results up to lifetime time horizon and calculated costs per quality-adjusted life year. METHODS Assuming equal efficacy, a cost-minimisation analysis compared IND/GLY vs IND + GLY using model inputs from the double-blind, randomised SHINE trial. The double-blind, randomised ILLUMINATE and TORCH trials were used to analyse cost-effectiveness versus SFC. To consider ICS-related pneumonia events, published odds ratio comparing an ICS-exposed group to a control group of COPD patients was used. Direct and indirect drug costs as well as drug acquisition costs (in Swedish Krona [SEK]) were derived from published Swedish sources. Cost and effects were discounted with 3%. Uncertainty was assessed by one-way and probabilistic sensitivity analyses (PSA). RESULTS IND/GLY was cost-saving vs IND + GLY with incremental savings of SEK (EUR) 768 (85), and 3309 (368) per patient over one and five years. IND/GLY was found to be less costly and more effective compared to SFC with cost savings of SEK (EUR) 2744 (303), 8854 (976), 13,938 (1536), 27,495 (3031) and 43,033 (4744) over one, three, five, ten years and lifetime. The PSA indicated that all iterations produced dominant results for IND/GLY. CONCLUSION IND/GLY is cost-minimising vs IND + GLY and dominates SFC in the maintenance treatment of COPD patients in Sweden. Encouraging dual bronchodilator therapy over an ICS-containing combination results in lower total costs and better outcomes compared to combination therapy including fluticasone in moderate-to-severe COPD patients with low exacerbation risk.
