Abstract
This review identifies and evaluates the comprehensive reporting of peer-reviewed economic evaluations of the effectiveness of fluticasone-propionate/salmeterol combination (FSC) therapy for maintenance treatment of chronic obstructive pulmonary disease (COPD). Economic evaluations were included if published in English since 2003. Evaluation categories included in the review were cost-effectiveness, cost-utility, and cost-consequence analyses. FSC is cost-effective in comparison to short-acting bronchodilators (SABDs). Cost and outcome differences between FSC and other long-acting therapies were modest. Studies exhibited large variations in populations, designs and environment, limiting the ability to draw conclusions. Many new maintenance treatments for COPD have been approved since 2010. Most have yet to be compared to older treatments like FSC. Evaluations are needed that consider costs and outcomes from a societal perspective (e.g., patients' ability to keep working) and evaluations that include subgroup analyses to investigate differential impacts according to clusters of patient characteristics.

ERJ Open Res 2016; 2:00034-2015.

Abstract
Chronic obstructive pulmonary disease (COPD) care across Europe has high heterogeneity with respect to cost and the services available. Variations in length of stay (LOS) may be attributed to patient characteristics, resource and organisational characteristics, and/or the so-called hospital cluster effect. The European COPD Audit in 13 countries included data from 16 018 hospitalised patients. The recorded variables included information on patient and disease characteristics, and resources available. Variables associated with LOS were evaluated by a multivariate, multilevel analysis. Mean±sd LOS was 8.7±8.3 days (median 7 days, interquartile range 4-11 days). Crude variability between countries was reduced after accounting for clinical factors and the clustering effect. The main factors associated with LOS being longer than the median were related to disease or exacerbation severity, including GOLD class IV (OR 1.77) and use of mechanical ventilation (OR 2.15). Few individual resource variables were associated with LOS after accounting for the hospital cluster effect. This study emphasises the importance of the patients' clinical severity at presentation in predicting LOS. Identifying patients at risk of a long hospital stay at admission and providing targeted interventions offers the potential to reduce LOS for these individuals. The complex interactions between factors and systems were more important that any single resource or organisational factor in determining differences in LOS between hospitals or countries.

Abstract
OBJECTIVE We aimed to identify the 100 top-cited articles published on chronic obstructive pulmonary disease (COPD) and to analyze their characteristics so as to provide information on the achievement and development in COPD research over the past decades. METHODS AND MATERIALS A comprehensive list of citation classics in COPD was generated by searching the Science Citation Index expanded database, using the keywords "COPD" or "chronic obstructive pulmonary disease" or "chronic obstructive pulmonary diseases". The 100 top-cited research papers were retrieved by reading the abstract or full text if needed. All eligible articles were read for basic information, including country of origin, organizations, article type, journals, research field, and authors. RESULTS The 100 top-cited articles on COPD were published between 1966 and 2010. The number of citations ranged from 254 to 2,164, with a mean of 450 citations for each article. These citation classics were from 32 countries, with 38 from the United States. The Imperial College London led the list of classics, with 16 papers. The 100 top-cited articles were distributed in 18 journals, with the American Journal of Respiratory, Critical Care Medicine, and Journal of the American Medical Association topping the list. Among the various fields, both respiratory system (63%) and general internal medicine (63%) were the most common fields of study for the 100 articles. CONCLUSION Our bibliometric analysis provides a historical perspective on the progress of scientific research on COPD. Articles originating from the United States and published in high-impact specialized respiratory journals are most likely to be cited in the field of COPD research.

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.

Cazzola M, Bardaro F, Stirpe E. The role of indacaterol for chronic obstructive pulmonary disease (COPD). J Thorac Dis 2013; 5:559-66. [PMID: 23991316 DOI: 10.3978/j.issn.2072-1439.2013.07.35] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2013] [Accepted: 07/26/2013] [Indexed: 11/14/2022]
Abstract
Indacaterol is the first long-acting β2-agonist (LABAs) approved for the treatment of chronic obstructive pulmonary disease (COPD) that allows for once-daily (OD) administration. It is rapidly acting, with an onset of action in 5 minutes, like salbutamol and formoterol but with a sustained bronchodilator effect, that last for 24 hours, like tiotropium. In long-term clinical studies (12 weeks to 1 year) in patients with moderate to severe COPD, OD indacaterol 150 or 300 μg improved lung function (primary endpoint) significantly more than placebo, and improvements were significantly greater than twice-daily formoterol 12 μg or salmeterol 50 μg, and noninferior to OD tiotropium bromide 18 μg. Indacaterol was well tolerated at all doses and with a good overall safety profile. Cost-utility analyses show that indacaterol 150 μg has lower total costs and better outcomes than tiotropium and salmeterol. These findings suggest that indacaterol can be considered a first choice drug in the treatment of the patient with mild/moderate stable COPD. However, in people with COPD who remain symptomatic on treatment with indacaterol, adding a long-acting muscarinic antagonist (LAMA) is the preferable option. In any case, it is advisable to combine indacaterol with a OD inhaled corticosteroid (ICS), such as mometasone furoate or ciclesonide, in patients with low FEV1, and, in those patients who have many symptoms and a high risk of exacerbations, to combine it with a LAMA and a OD ICS.
