Abstract
While politics can determine what public goods are available, elected officials must decide on the method of allocation. Commonly, governments provide public health insurance directly or pay private parties to administer it on their behalf. Such contracting can leverage private sector expertise but also raises agency concerns. In particular, little is known about how private provision of public health insurance impacts medical decision-making and treatment flows for low-income populations. An example comes from the Medicaid program, which has increasingly relied on outside insurers to deliver health services to enrollees. We exploit a large legislative intervention in Florida to show that Medicaid managed care (MMC) organizations generally do not skimp on short-run treatment delivery in the inpatient setting. In fact, patients with severe and chronic illnesses receive more inpatient services under these contracts, especially in relation to managing care transitions. We also document increased competition in the MMC market following the state's policy intervention.

Abstract
INTRODUCTION Multimorbidity, the presence of 2 or more chronic conditions, frequently affects people with chronic obstructive pulmonary disease (COPD). Many have high-cost, highly complex conditions that have a substantial impact on state Medicaid programs. We quantified the cost of Medicaid-insured patients with COPD co-diagnosed with other chronic disorders. METHODS We used nationally representative Medicaid claims data to analyze the impact of comorbidities (other chronic conditions) on the disease burden, emergency department (ED) use, hospitalizations, and total health care costs among 291,978 adult COPD patients. We measured the prevalence of common conditions and their influence on COPD-related and non-COPD-related resource use by using the Elixhauser Comorbidity Index. Elixhauser comorbidity counts were clustered from 0 to 7 or more. We performed multivariable logistic regression to determine the odds of ED visits by Elixhauser scores adjusting for age, sex, race/ethnicity, and residence. RESULTS Acute care, hospital bed days, and total Medicaid-reimbursed costs increased as the number of comorbidities increased. ED visits unrelated to COPD were more common than visits for COPD, especially in patients self-identified as black or African American (designated black). Hypertension, diabetes, affective disorders, hyperlipidemia, and asthma were the most prevalent comorbid disorders. Substance abuse, congestive heart failure, and asthma were commonly associated with ED visits for COPD. Female sex was associated with COPD-related and non-COPD-related ED visits. CONCLUSION Comorbidities markedly increased health services use among people with COPD insured with Medicaid, although ED visits in this study were predominantly unrelated to COPD. Achieving excellence in clinical practice with optimal clinical and economic outcomes requires a whole-person approach to the patient and a multidisciplinary health care team.

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.

Abstract
BACKGROUND Despite the importance of respiratory medication use in COPD, relatively little is known about which clinical phenotypes were associated with respiratory medications. METHODS To determine the association between respiratory medication use and exacerbations or quantitative CT metrics, we analyzed medication history from 4,484 COPD subjects enrolled in the COPDGene Study. RESULTS 2,941 (65.6%) subjects were receiving one or more respiratory medications; this group experienced more frequent exacerbations in the year before study entry and had increased gas trapping, emphysema, and subsegmental airway wall area, compared to the patients who were on no respiratory medication. In subgroup analysis, subjects who were on triple therapy (long-acting beta2-agonist [LABA], long-acting muscarinic antagonist [LAMA], and inhaled corticosteroids [ICS]) had the highest frequencies of exacerbations and severe exacerbations and tended to have increased quantitative measures of emphysema and gas trapping on CT compared to other five groups. After adjustment for confounding variables, the triple therapy group experienced more exacerbations and severe exacerbations compared with other five groups. In addition, the LABA+LAMA+ICS group was more likely to have emphysema and gas trapping on CT than other groups in multivariable logistic analysis. Interestingly, the total number of respiratory medications was significantly associated with not only the frequency of exacerbations but also gas trapping and airway wall thickness as assessed by CT scan in multivariable analysis. CONCLUSIONS These results suggest that the use of respiratory medications, especially the number of medications, may identify a more severe phenotype of COPD that is highly susceptible to COPD exacerbations.

Abstract
The objective of the study was to assess whether the incidences of Crohn's disease and ulcerative colitis are increased in patients with asthma and chronic obstructive pulmonary disease (COPD) compared to the general population. A population-based retrospective cohort study was conducted using the administrative health databases of Québec, Canada. Incidences of Crohn's disease and ulcerative colitis among patients with asthma and COPD were assessed for the 2001-2006 period. In total, 136 178 subjects with asthma and 143 904 subjects with COPD were identified. The average incidence of Crohn's disease and ulcerative colitis was 23.1 and 8.8 per 100 000 person-years among asthmatic patients; in the COPD cohort there were 26.2 Crohn's disease cases and 17 ulcerative colitis cases per 100 000 person-years. The incidence of Crohn's disease in asthma and COPD patients was 27% and 55% higher than in the general population of Québec; the incidence of ulcerative colitis was 30% higher among COPD patients compared to the general population. Incidence of inflammatory bowel disease was significantly increased in asthma and COPD patients compared to the general population of Québec. Incidence rates were particularly high in patients with COPD. Awareness of an association between airway diseases and inflammatory bowel disease in older age groups may play an important role in earlier detection of bowel disease and in the therapeutic management of such patients.

Abstract
OBJECTIVE To evaluate the clinical and economic burden of COPD patients to Medicaid. STUDY DESIGN Retrospective, observational matched cohort design. METHODS We calculated the incremental costs incurred and medical resources used by COPD patients relative to those without COPD. Data were obtained from 8 Medicaid states during 2003-2007. COPD patients were defined as Medicaid beneficiaries ≥40 years with a COPD diagnosis (ICD-9 CM: 491.xx, 492.xx, 496.xx) and treated with maintenance drugs for COPD. Patients were matched (1:3) to Medicaid beneficiaries without a COPD diagnosis on age, gender, race, index year, Medicare/Medicaid dual eligibility, and use of long-term care. Results were stratified by Medicare/Medicaid dual eligibility status and race. RESULTS A total of 10,221 COPD and 30,663 non-COPD patients were included. Cohorts were on average 65 years of age, 80% White, and 64.8% having Medicare/Medicaid dual eligibility. Inpatient hospitalizations and home healthcare visits/durable medical equipment were primary drivers of incremental medical costs. COPD patients were more than twice as likely to have a hospitalization (odds ratio [95% confidence interval] = 2.32 [2.19, 2.45]) or home healthcare visit/durable medical equipment (2.95 [2.82, 3.08]) compared to non-COPD patients. Medicaid incurred $2118/year in incremental costs due to COPD. On average, incremental costs were 7 times greater for non-dual-eligible patients ($4917) compared to dual-eligible patients ($667), and were more than double for Blacks compared to Whites ($4141 vs $1593). CONCLUSION COPD imposes a substantial economic and clinical burden on the Medicaid program; this burden differs by dual eligibility status and race.

Abstract
Cancer patients, especially those with lung cancer and undergoing chemotherapy, have an elevated risk for venous thromboembolism (VTE). This study assessed incidence, timing, and risk factors for VTE (specifically receipt of chemotherapy), along with the association between VTE and survival among lung cancer patients receiving chemotherapy. Using Florida Medicaid administrative claims data (2000-2008), patients with any diagnosis of primary lung cancer were selected. Patients with recent prior VTE and those enrolled in Medicare or an HMO were excluded. Crude rates of VTE per 100 person years were estimated, and Cox proportional hazards models were developed to assess risk factors for VTE in the lung cancer population, and the association between VTE and survival among patients undergoing chemotherapy. Of 15,749 lung cancer patients, 7,052 (2,242 receiving chemotherapy and 4,810 not receiving chemotherapy) met cohort selection criteria. The incidence of VTE was 10.8 per 100 person-years (PYs) in the chemotherapy cohort and 6.8 per 100 PYs in the non-chemotherapy cohort. Among patients on chemotherapy developing VTE, median time to occurrence was 109 days, with 61 and 82 % of patients experiencing an event within six and 12 months, respectively. In multivariate analyses, the adjusted risk of VTE was 30 % higher among patients undergoing chemotherapy. Comorbidity and the presence of a central venous catheter also were significantly associated with a greater risk of developing VTE. Moreover, patients in the chemotherapy cohort who developed VTE had a significantly faster time-to-death (adjusted hazard ratio [HR] = 1.97; 95 % CI 1.69-2.29).VTE was common among lung cancer patients, especially among patients receiving chemotherapy, with the majority of VTE events occurring within 6 months of initiation of chemotherapy. The presence of a VTE event was significantly associated with an increased risk of mortality.

Abstract
Chronic obstructive pulmonary disease (COPD) affects approximately 7% of Americans. COPD impacts productivity and forces 1 in 5 employees ages 45-65 years old to retire prematurely. Our objective was to quantify the direct and indirect costs of COPD in an employed population in the United States. A retrospective analysis using Thomson Reuters MarketScan commercial claims and Health and Productivity (HPM) databases (2000-2007) identified employees (ages 18-65 years) with ≥ 1 COPD medical claim, ≥ 6 month insurance eligibility pre and ≥ 12 months post diagnosis, and ≥ 12 months HPM data post diagnosis. COPD subjects were matched to non-COPD subjects using propensity scores to create a comparison group with similar characteristics. Differences in medical and pharmacy utilization and productivity (absence and short-term disability [STD] days) were examined using negative binomial regression, and cost differences using Heckman selection models. A total of 27,612 COPD patients were matched in a 1:1 ratio to 825,884 non-COPD patients; 80% were ages 36-65 years, and 59% were male. COPD employees had about twice the rate of emergency department visits and hospitalizations compared to non-COPD employees (P<0.0001). The rate of absence and STD days was approximately 1.5 times higher (P<0.0001) compared to non-COPD employees. Yearly direct and indirect expenditures were higher ($3609 and $909, respectively; P<0.0001) for COPD versus non-COPD employees. Excess utilization and associated costs of COPD to employers was quantified. By understanding these costs, employers may evaluate disease management programs and treatment to improve outcomes for employees with COPD. Improved treatment options may reduce the direct and indirect costs of COPD.

Abstract
AIM While it is known that severe COPD has substantial economic consequences, evidence on resource use and costs in mild disease is scarce. The objective of this study was to investigate excess costs of early stages of COPD. METHODS Using data from two population-based studies in Southern Germany, current GOLD criteria were applied to pre-bronchodilator spirometry for COPD diagnosis and staging in 2255 participants aged 41 to 89. Utilization of physician visits, hospital stays and medication was compared between participants with COPD stage I, stage II+ (II or higher) and controls. Costs per year were calculated by applying national unit costs. In controlling for confounders, two-part generalized regression analyses were used to account for the skewed distribution of costs and the high proportion of subjects without costs. RESULTS Utilization in all categories was significantly higher in COPD patients than in controls. After adjusting for confounders, these differences remained present in physician visits and medication, but not in hospital days. Adjusted annual costs did not differ between stage I (€ 1830) and controls (€ 1822), but increased by about 54% to € 2812 in stage II+. CONCLUSION The finding that utilization and costs are considerably higher in moderate but not in mild COPD highlights the economic importance of prevention and of interventions aiming at early diagnosis and delayed disease progression.

Abstract
BACKGROUND Exacerbations are a major contributor to the large burden of treating chronic obstructive pulmonary disease (COPD). Estimates of exacerbation costs in the United States are limited. OBJECTIVE To estimate incremental costs associated with COPD exacerbation, particularly severe exacerbation, in the United States. METHODS COPD patients with at least one exacerbation were identified in the Thomson Reuters MarketScan administrative claims database. A COPD exacerbation was defined as patient use of oral or parenteral corticosteroids on the same day or within 7 days following a claim with a COPD diagnosis. Severe exacerbation was further defined if the exacerbation was associated with hospitalization or death. Healthcare costs and exacerbations were evaluated at quarterly intervals starting from patients' first observed claim with COPD diagnostic code in the database. Incremental costs associated with exacerbation were estimated as cost differences between quarters with exacerbation and quarters without exacerbation. RESULTS A total of 2644,174 patient-quarters, derived from 228,978 COPD patients, were included in the analysis. The average patient was followed an average of 2.9 years. The mean total cost was $17,016 per patient-quarter with severe exacerbation, $6628 per patient-quarter with non-severe exacerbation, an average of $8726 per patient-quarters with any exacerbation compared to $4762 per patient-quarter with no exacerbation. After adjusting for patient demographics, the mean incremental total cost was $11,261 per patient-quarter with severe exacerbation, $1509 per patient-quarter for non-severe exacerbation, and $3439 per patient-quarter with any exacerbation compared with patient-quarters with no exacerbation. LIMITATIONS The method used for defining exacerbations does not capture mild exacerbations. Additional limitations exist due to the nature of claims data. CONCLUSIONS Exacerbations, especially severe ones, result in a significant economic burden for third-party payers. Effective management of COPD and prevention of exacerbations may lead to improved patient outcomes and reduction in total healthcare costs for long-term management of COPD.

Abstract
OBJECTIVE Treatment in the hospital setting accounts for the largest portion of healthcare costs for COPD, but there is little information about components of hospital care that contribute most to these costs. The authors determined the costs and characteristics of COPD-related hospital-based healthcare in a Medicare population. METHODS Using administrative data from 602 hospitals, 2008 costs of COPD-related care among Medicare beneficiaries age ≥ 65 years were calculated for emergency department (ED) visits, simple inpatient admissions and complex admissions (categorized as intubation/no intensive care, intensive care/no intubation, and intensive care/intubation) in a cross-sectional study. Rates of death at discharge and trends in costs, length of stay and readmission rates from 2005 to 2008 also were examined. MAIN RESULTS There were 45,421 eligible healthcare encounters in 2008. Mean costs were $679 (SD, $399) for ED visits (n = 10,322), $7,544 ($8,049) for simple inpatient admissions (n = 25,560), and $21,098 ($46,160) for complex admissions (n = 2,441). Intensive care/intubation admissions (n = 460) had the highest costs ($45,607, SD $94,794) and greatest length of stay (16.3 days, SD 13.7); intubation/no ICU admissions had the highest inpatient mortality (42.1%). In 2008, 15.4% of patients with a COPD-related ED visit had a repeat ED visit and 15.5-16.5% of those with a COPD-related admission had a readmission within 60 days. From 2005 to 2008, costs of admissions involving intubation increased 10.4-23.5%. Study limitations include the absence of objective clinical data, including spirometry and smoking history, to validate administrative data and permit identification of disease severity. CONCLUSIONS In this Medicare population, COPD exacerbations and related inpatient and emergency department care represented a substantial cost burden. Admissions involving intubation were associated with the highest costs, lengths of stay and inpatient mortality. This population needs to be managed and treated adequately in order to prevent these severe events.

Abstract
INTRODUCTION Atrial fibrillation (AF) has been shown to be associated with high healthcare costs; however, limited data are available from large-scale studies quantifying the overall cost burden of AF in the USA. We therefore aimed to provide an up to date estimate of the overall per-patient costs of AF in managed care organizations across the USA. METHODS This retrospective cohort study used claims data from the Integrated Healthcare Information Systems National Managed Care Benchmark Database from January 2005 to December 2006. Patients included in the analysis were aged > or =20 years and had at least two outpatient AF-related claims without hospitalization, or a hospitalization with a primary or secondary discharge diagnosis of AF in 2005. AF-related inpatient and outpatient costs over 12 months from the initial outpatient claim or first hospitalization were examined. For secondary AF hospitalizations, incremental costs associated with AF were measured by comparing costs for patients with AF with a group of matched controls hospitalized without AF. RESULTS In total, 35,255 patients diagnosed as having AF (5008 with a primary AF diagnosis, 10,776 with a secondary AF diagnosis, 19,471 with outpatient-managed AF), and 20,571 controls without AF, were included in the analysis. Over 12 months, for primary AF hospitalization patients, inpatient costs were $11,306.53 and outpatient costs were $2826.78 (total $14,133.30) per patient. For hospitalized patients with secondary AF, incremental AF-related inpatient costs were $5181.19 and outpatient costs were $1376.33 (total $6557.52). For AF patients with outpatient management in 2005, 12-month AF-related costs were $2177.30 ($175.47 for AF hospitalizations in 2006 and $2001.85 for outpatient costs). CONCLUSIONS Overall costs of AF in the US managed care organizations are high. Costs are primarily due to inpatient expenses. Improved disease management strategies to reduce AF-related hospitalizations and decrease the overall cost burden of AF are needed.

Abstract
The costs of chronic obstructive pulmonary disease (COPD) pose a major economic burden to the United States. Studies evaluating COPD costs have generated widely variable estimates; we summarized and critically compared recent estimates of the annual national and per-patient costs of COPD in the U.S. Thirteen articles reporting comprehensive estimates of the direct costs of COPD (costs related to the provision of medical goods and services) were identified from searches of relevant primary literature published since 1995. Few papers reported indirect costs of COPD (lost work and productivity). The National Heart, Lung, and Blood Institute (NHLBI) provides the single current estimate of the total (direct plus indirect) annual cost of COPD to the U.S., $38.8 billion in 2005 dollars. More than half of this cost ($21.8 billion) was direct, aligning with the $20-26 billion range reported by two other recent analyses of large national datasets. For per-patient direct costs (in $US 2005), studies using recent data yield attributable cost estimates (costs deemed to be related to COPD) in the range of $2,700-$5,900 annually, and excess cost estimates (total costs incurred by COPD patients minus total costs incurred by non-COPD patients) in the range of $6,100-$6,600 annually. Studies of both national and per-patient costs that use data approximately 8-10 years old or older have produced estimates that tend to deviate from these ranges. Cost-of-illness studies using recent data underscore the substantial current cost burden of COPD in the U.S.

Abstract
OBJECTIVE To estimate the costs of undiagnosed chronic obstructive pulmonary disease (COPD) by describing inpatient, outpatient, and pharmacy utilization in the years before and after the diagnosis. METHODS A total of 6,864 patients who were enrolled in the Lovelace Health Plan for at least 12 months during the study period (January 1, 1999 through December 31, 2004) were identified. The first date that utilization was attributed to COPD was considered the first date of diagnosis. Each COPD case was matched to up to three age- and sex-matched controls. All utilization and direct medical costs during the study period were compiled monthly and compared based on the time before and after the initial diagnosis. RESULTS Total costs were higher by an average of $1,182 per patient in the 2 years before the initial COPD diagnosis, and $2,489 in the 12 months just before the initial diagnosis, compared to matched controls. Most of the higher cost for undiagnosed COPD was attributable to hospitalizations. Inpatient costs did not increase after the diagnosis was made, but approximately one-third of admissions after the diagnosis were attributed to respiratory disease. Outpatient and pharmacy costs did not differ substantially between cases and matched controls until just a few months before the initial diagnosis, but remained 50% to 100% higher than for controls in the 2 years after diagnosis. CONCLUSIONS Undiagnosed COPD has a substantial impact on health-care costs and utilization in this integrated managed care system, particularly for hospitalizations.

Abstract
BACKGROUND Asthma and COPD can significantly affect patients and pose a substantial economic burden for both patients and managed-care plans. This study compares utilization outcomes in patients with asthma, COPD, or co-occurring asthma and COPD in a Medicaid population, and assesses the incremental burden of COPD in patients with asthma. METHODS We queried medical claims of Medicaid patients aged 40 to 64 years with asthma and/or COPD filed between January 1, 2001, and December 31, 2003, from encounter data. COPD patients were identified based on at least one claim with International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9) codes 491, 492, 496; and asthma patients were identified on the basis of ICD-9 code 493 as diagnosis. We analyzed annual utilization and cost of hospitalizations, physician, and outpatient services attributable to asthma and/or COPD. RESULTS The analysis included a total of 3,072 asthma, 3,455 COPD, and 2,604 COPD/asthma patients. COPD/asthma co-occurring disease has higher utilization of any service type than either disease alone. Compared with asthma patients, COPD patients were 16% and 51% more likely to use physician (odds ratio [OR], 1.16; 95% confidence interval [CI], 1.01 to 1.34) and inpatient services (OR, 1.51; 95% CI, 1.31 to 1.74), respectively; and 60% less likely to use outpatient services (OR, 0.40; 95% CI, 0.35 to 0.46). Compared with asthma patients, COPD patients and COPD/asthma co-occurring patients cost 50% (OR, 1.50; 95% CI, 1.3 to 1.74) and five times (OR, 5.25; 95% CI, 4.59 to 6.02) more for total medical services, respectively. CONCLUSION Our data suggest that patients with COPD and co-occurring COPD/asthma were sicker and used more medical services than asthma patients. The incremental burden of COPD to patients with asthma is significant.

Abstract
BACKGROUND Limited information is available on the relative outcomes and treatment costs of various pharmacotherapies for chronic obstructive pulmonary disease (COPD) in a Medicaid population. OBJECTIVE This study compared the effects of initial medication regimens for COPD on COPD-related and all-cause events (hospitalizations and/or emergency department [ED] visits) and COPD-related and all-cause costs. METHODS The study population was a historical cohort of Texas Medicaid beneficiaries aged 40 to 64 years with COPD-related medical costs (International Classification of Diseases, Ninth Revision, Clinical Modification codes 491.xx, 492.xx, 496.xx), 24 months of continuous Medicaid enrollment (12 months before and after the index prescription), and at least 1 prescription claim (index) for a combination product containing fluticasone propionate + salmeterol, an inhaled corticosteroid, salmeterol, or ipratropium between April 1, 2001, and March 31, 2003. The analyses of events employed Cox proportional hazards regression, controlling for baseline factors and preindex events. The analyses of costs used a 2-part model with logistic regression and generalized linear model to adjust for baseline characteristics and preindex utilization and costs. RESULTS The study population included 6793 patients (1211 combination therapy, 968 inhaled corticosteroid, 401 salmeterol, and 4213 ipratropium). Only combination therapy was associated with a significantly lower risk for any COPD-related event (hazard ratio [HR] = 0.733; 95% CI, 0.650-0.826) and any all-cause event (HR = 0.906; 95% CI, 0.844-0.972) compared with ipratropium. COPD-related prescription costs were higher in all cohorts compared with the ipratropium cohort, but COPD-related medical costs were lower, offsetting the increase in prescription costs. For all-cause costs, prescription costs were higher in the combination-therapy cohort (+$415; P < 0.05) and the salmeterol cohort (+$247; P < 0.05) compared with the ipratropium cohort, but significant reductions in all-cause medical costs in the combination-therapy cohort (-$1735; P < 0.05) and salmeterol cohort (-$1547; P < 0.05) more than offset the increase in prescription costs. CONCLUSIONS In this historical population of Texas Medicaid beneficiaries, the combination-therapy cohort was 27% less likely to have a COPD-related event than the ipratropium cohort, 10% less likely to have any all-cause event, had similar COPD-related costs, and had reduced all-cause costs. Thus, compared with the ipratropium cohort, the combination-therapy cohort had an improvement in outcomes (based on the decreased time to a hospitalization or ED visit), with similar or decreased direct medical costs. Future research is needed in other patient groups.

Abstract
In 2002, an estimated 11.2 million adults in the United States had chronic obstructive pulmonary disease (COPD). Guidelines for the management of the disease have been published by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) and the American Thoracic Society-European Respiratory Society. Several other organizations are in the process of preparing guidelines for COPD, most based on the GOLD report. The most important pharmacologic intervention in COPD is treatment with bronchodilator drugs. This intervention applies not only to stable COPD, but also to exacerbations (flares) of the disease. Prevention strategies have been developed for acute exacerbations, and management strategies include using short-acting beta(2)-agonists, systemic corticosteroids, and antibiotics, in both at home and hospital settings.
