Background: The overall burden of bronchiectasis on patients and healthcare systems has not been comprehensively described. Here, we present the findings of a systematic literature review that assessed the clinical and socioeconomic burden of bronchiectasis with subanalyses by aetiology (PROSPERO registration: CRD42023404162)., Methods: Embase, MEDLINE and the Cochrane Library were searched for publications relating to bronchiectasis disease burden (December 2017-December 2022). Journal articles and congress abstracts reporting on observational studies, randomised controlled trials and registry studies were included. Editorials, narrative reviews and systematic literature reviews were included to identify primary studies. PRISMA guidelines were followed., Results: 1585 unique publications were identified, of which 587 full texts were screened and 149 were included. A further 189 citations were included from reference lists of editorials and reviews, resulting in 338 total publications. Commonly reported symptoms and complications included dyspnoea, cough, wheezing, sputum production, haemoptysis and exacerbations. Disease severity across several indices and increased mortality compared with the general population was reported. Bronchiectasis impacted quality of life across several patient-reported outcomes, with patients experiencing fatigue, anxiety and depression. Healthcare resource utilisation was considerable and substantial medical costs related to hospitalisations, treatments and emergency department and outpatient visits were accrued. Indirect costs included sick pay and lost income., Conclusions: Bronchiectasis causes significant clinical and socioeconomic burden. Disease-modifying therapies that reduce symptoms, improve quality of life and reduce both healthcare resource utilisation and overall costs are needed. Further systematic analyses of specific aetiologies and paediatric disease may provide more insight into unmet therapeutic needs., Competing Interests: Conflict of interest: The authors meet criteria for authorship as recommended by the International Committee of Medical Journal Editors (ICMJE).

Background: Bronchiectasis carries a significant economic burden with high health care expenditures associated with frequent hospitalizations, physician visits, and treatments, including oral and intravenous antibiotics for repeated lung infections, airway-clearance therapy, and oxygen administration. Bronchiectasis exacerbations can contribute to this burden., Objective: To estimate US health care resource utilization (HCRU) and costs associated with bronchiectasis and with bronchiectasis exacerbations., Methods: This retrospective study used the 100% Medicare Fee-for-Service database (January 2014 to December 2020) to compare HCRU and costs among patients with bronchiectasis with those of patients without bronchiectasis (controls). For patients with bronchiectasis, the index date was a randomly selected bronchiectasis claim after more than 1 year of disease history and, for controls, a claim closest to their matched bronchiectasis patient's index date. All patients had continuous enrollment for at least 12 months pre-index (baseline) and at least 12 months post-index. Primary outcomes were all-cause, respiratory-related, and bronchiectasis-related HCRU and health care costs, which were presented by the overall sample and by segmented patient cohorts based on the number of exacerbations during baseline (0, 1, or ≥2)., Results: 92,529 patients with bronchiectasis (mean [SD] age, 76.7 [8.8] years; 72.3% female) and 92,529 matched controls qualified for the study. Compared with controls, patients with bronchiectasis presented greater mean (SD) all-cause physician visits (15.4 [10.0] vs 13.2 [9.7]; P < 0.001) and respiratory-related physician visits (5.2 [4.3] vs 1.9 [3.1]), pulmonologist visits (1.9 [2.2] vs 0.3 [1.0]), hospitalizations (0.4 [0.9] vs 0.3 [0.8]), emergency department visits (0.33 [1.0] vs 0.26 [1.0]), and total health care costs ($10,224 [$23,263] vs $6,704 [$19,593]). Respiratory-related HCRU was also greater in patients with more baseline exacerbations, with total health care costs of $8,506, $10,365, and $14,790 for patients with 0, 1, and at least 2 exacerbations, respectively ( P < 0.01)., Conclusions: This real-world study demonstrates the high disease burden associated with bronchiectasis and with exacerbations, highlighting the need to improve management and reduce exacerbations.

Aims: Non-cystic fibrosis bronchiectasis (NCFB) is a chronic progressive respiratory disorder occurring at a rate ranging from 4.2 to 278.1 cases per 100,000 persons, depending on age, in the United States. For many patients with NCFB, the presence of Pseudomonas aeruginosa (PA) makes treatment more complicated and typically has worse outcomes. Management of NCFB can be challenging, warranting a better understanding of the burden of illness for NCFB, treatments applied, healthcare resources used, and subsequent treatment costs. Comparing patients diagnosed with exacerbated NCFB, with or without PA on antibiotic utilization, treatments, and healthcare resources utilization and costs was the purpose of this study., Materials and Methods: This was a retrospective cohort study of commercial claims from IQVIA's PharMetrics Plus database (January 1,2006-December 31, 2020). Study patients with a diagnosis of NCFB were stratified into two groups based on the presence or absence of PA, then followed to identify demographic characteristics, comorbid conditions, antibiotic treatment regimen prescribed, healthcare resources utilized, and costs of care., Results: The results showed that patients with exacerbated NCFB who were PA + had significantly more oral antibiotic fills per patient per year, more inpatient admissions with a longer length of stay, and more outpatient encounters than those who were PA - . For costs, PA + patients also had significantly greater total healthcare costs per patient when compared to those who were PA - ., Conclusion: Exacerbated NCFB with PA + was associated with increased antibiotic usage, greater resource utilization, and increased costs. The major contributor to the cost differences was the use of inpatient services. Treatment strategies aimed at reducing the need for inpatient treatment could lessen the disparities observed in patients with NCFB.

Background: The burden of hospitalizations and mortality for hemoptysis due to bronchiectasis is not well characterized. The primary outcome of our study was to evaluate in-hospital mortality in patients admitted with hemoptysis and bronchiectasis, as well as the rates of bronchial artery embolization, length of stay, and hospitalization costs., Methods: The authors queried the Nationwide Inpatient Sample (NIS) claims database for hospitalizations between 2016 and 2017 using the ICD-10-CM codes for hemoptysis and bronchiectasis in the United States. Multivariable regression was used to evaluate predictors of in-hospital mortality, embolization, length of stay, and hospital costs., Results: There were 8240 hospitalizations (weighted) for hemoptysis in the United States from 2016 to 2017. The overall in-hospital mortality was 4.5%, but higher in males compared to females. Predictors of in-hospital mortality included undergoing three or more procedures, age, and congestive heart failure. Bronchial artery embolization (BAE) was utilized during 2.1% of hospitalizations and was more frequently used in those with nontuberculous mycobacteria and aspergillus infections, but not pseudomonal infections. The mean length of stay was 6 days and the median hospitalization cost per patient was USD $9,610. Having comorbidities and procedures was significantly associated with increased length of stay and costs., Conclusion: Hemoptysis is a frequent indication for hospitalization among the bronchiectasis population. In-hospital death occurred in approximately 4.5% of hospitalizations. The effectiveness of BAE in treating and preventing recurrent hemoptysis from bronchiectasis needs to be explored., (© 2021.

Background and Objective: Despite paediatric bronchiectasis being recognized increasingly worldwide, prior reports of hospitalization costs for bronchiectasis in children are lacking. This study aimed to (i) identify health service costs of hospitalizations and (ii) factors associated with these costs in children admitted to an Australian paediatric hospital following an acute exacerbation of their bronchiectasis., Methods: Demographic and hospital resource use data were prospectively recorded for 100 hospitalizations in 80 children aged <18 years admitted consecutively to the QCH, Brisbane, Australia. Costs (2016 AUD) were obtained from the hospital's Finance Department. Linear regressions, with bootstrap resampling to quantify uncertainty, were used to estimate factors affecting cost of hospitalization., Results: The 100 hospitalizations (48 males) had a median (IQR) age of 6.04 (4.04-9.85) years. Their mean (SD) LOS was 12.30 (4.60) days. The mean (SD) direct health service cost was AUD 30 182 (13 998) per hospitalization. The greatest contributor to costs was health professional wages, accounting for 70% of the cost per episode. LOS, younger age at admission and number of bronchiectatic lobes affected were associated with higher costs, whilst HITH service was associated with lower cost. The cost to families on average was AUD 2669.50 (SD: 991.50) per hospitalization when accounting for lost wages and opportunity cost., Conclusion: The per episode healthcare cost burden of hospitalizations for paediatric bronchiectasis exacerbations is substantial. Interventions that prevent hospitalized exacerbations and reduce severity of childhood bronchiectasis with even moderate effectiveness are likely to result in substantial hospital costs savings., (© 2020 Asian Pacific Society of Respirology.)

Objective: Bronchiectasis is a common chronic airway disease. We investigated the economic burden and associated factors of bronchiectasis in China., Methods: In this multicenter retrospective cohort study, we reviewed medical records of patients admitted to 18 tertiary hospitals during 2010 to 2014 with a bronchiectasis-related diagnosis., Results: A total 5469 patients with bronchiectasis were admitted, accounting for 3.13% ± 1.80% of all discharged patients with any diagnosis during the same period; 13 patients died upon discharge. The median hospitalization cost was RMB 8421.52 (RMB 5849.88-12,294.47). Risk factors associated with hospitalization costs included age at admission (>70 vs. <40 years, odds ratio (OR) = 1.221, 95% confidence interval (CI) = 1.082-1.379; >80 vs. <40 years, OR = 1.251, 95% CI = 1.089-1.438), smoking (≤15 packs/year vs. non-smokers, OR = 1.125, 95% CI = 1.006-1.271; >15 packs/year vs. non-smokers, OR = 1.127, 95% CI = 1.062-1.228), length of hospitalization (OR = 1.05, 95% CI = 1.046-1.054), combination antibiotic treatment (OR = 1.089, 95% CI = 1.033-1.148), cough (OR = 0.851, 95% CI = 0.751-0.965), dyspnea (OR = 0.93, 95% CI = 0.878-0.984), chronic obstructive pulmonary disease (OR = 0.935, 95% CI = 0.878-0.996), respiratory failure (OR = 0.923, 95% CI = 0.862-0.989), cor pulmonale (OR = 0.919, 95% CI = 0.859-0.982), and death (OR = 1.816, 95% CI = 1.113-2.838)., Conclusions: Age, smoking status, symptoms, and respiratory comorbidities were associated with hospitalization costs of bronchiectasis.

Background: Bronchiectasis in children is an important, but under-researched, chronic pulmonary disorder that has negative impacts on health-related quality of life. Despite this, it does not receive the same attention as other chronic pulmonary conditions in children such as cystic fibrosis. We measured health resource use and health-related quality of life over a 12-month period in children with bronchiectasis., Methods: We undertook a prospective cohort study of 85 children aged < 18-years with high-resolution chest computed-tomography confirmed bronchiectasis undergoing management in three pediatric respiratory medical clinics in Darwin and Brisbane, Australia and Auckland, New Zealand. Children with cystic fibrosis or receiving cancer treatment were excluded. Data collected included the frequency of healthcare attendances (general practice, specialists, hospital and/or emergency departments, and other), medication use, work and school/childcare absences for parents/carers and children respectively, and both parent/carer and child reported quality of life and cough severity., Results: Overall, 951 child-months of observation were completed for 85 children (median age 8.7-years, interquartile range 5.4-11.3). The mean (standard deviation) number of exacerbations was 3.3 (2.2) per child-year. Thirty of 264 (11.4%) exacerbation episodes required hospitalization. Healthcare attendance and antibiotic use rates were high (30 and 50 per 100 child-months of observation respectively). A carer took leave from work for 53/236 (22.5%) routine clinic visits. Absences from school/childcare due to bronchiectasis were 24.9 children per 100 child-months. Quality of life scores for both the parent/carer and child were highly-correlated with one another, remained stable over time and were negatively associated with cough severity., Conclusions: Health resource use in this cohort of children is high, reflecting their severe disease burden. Studies are now needed to quantify the direct and societal costs of disease and to evaluate interventions that may reduce disease burden, particularly hospitalizations.

Estimates of healthcare costs for incident bronchiectasis patients are currently not available for any European country.Out of a sample of 4 859 013 persons covered by German statutory health insurance companies, 231 new bronchiectasis patients were identified in 2012. They were matched with 685 control patients by age, sex and Charlson Comorbidity Index, and followed for 3 years.The total direct expenditure during that period per insured bronchiectasis patient was EUR18 634.57 (95% CI EUR15 891.02-23 871.12), nearly one-third higher (ratio of mean 1.31, 95% CI 1.02-1.68) than for a matched control (p<0.001). Hospitalisation costs contributed to 35% of the total and were >50% higher in the bronchiectasis group (ratio of mean 1.56, 95% CI 1.20-3.01; p<0.001); on average, bronchiectasis patients spent 4.9 (95% CI 2.27-7.43) more days in hospital (p<0.001). Antibiotics expenditures per bronchiectasis outpatient (EUR413.81) were nearly 5 times higher than those for a matched control (ratio of mean 4.85, 95% CI 2.72-8.64). Each bronchiectasis patient had on average 40.5 (95% CI 17.1-43.5) sick-leave days and induced work-loss costs of EUR4230.49 (95% CI EUR2849.58-5611.20). The mortality rate for bronchiectasis and matched non-bronchiectasis patients after 3 years of follow-up was 26.4% and 10.5%, respectively (p<0.001). Mortality in the bronchiectasis group was higher among those who also had chronic obstructive lung disease than in patients with bronchiectasis alone (35.9% and 14.6%, respectively; p<0.001).Although bronchiectasis is considered underdiagnosed, the mortality and associated financial burden in Germany are substantial., Competing Interests: Conflict of interest: R. Diel reports grants from Bayer Vital, during the conduct of the study; personal fees for advisory board work, consultancy and lectures from Insmed Inc., personal fees for advisory board work and consultancy from Bayer Vital, outside the submitted work.

Background: The increasing prevalence and recognition of bronchiectasis in clinical practice necessitates a better understanding of the economic disease burden to improve the management and achieve better clinical and economic outcomes. This study aimed to assess the economic burden of bronchiectasis based on a review of published literature., Methods: A systematic literature review was conducted using MEDLINE, Embase, EconLit and Cochrane databases to identify publications (1 January 2001 to 31 December 2016) on the economic burden of bronchiectasis in adults., Results: A total of 26 publications were identified that reported resource use and costs associated with management of bronchiectasis. Two US studies reported annual incremental costs of bronchiectasis versus matched controls of US$5681 and US$2319 per patient. Twenty-four studies reported on hospitalization rates or duration of hospitalization for patients with bronchiectasis. Mean annual hospitalization rates per patient, reported in six studies, ranged from 0.3-1.3, while mean annual age-adjusted hospitalization rates, reported in four studies, ranged from 1.8-25.7 per 100,000 population. The average duration of hospitalization, reported in 12 studies, ranged from 2 to 17 days. Eight publications reported management costs of bronchiectasis. Total annual management costs of €3515 and €4672 per patient were reported in two Spanish studies. Two US studies reported total costs of approximately US$26,000 in patients without exacerbations, increasing to US$36,00-37,000 in patients with exacerbations. Similarly, a Spanish study reported higher total annual costs for patients with > 2 exacerbations per year (€7520) compared with those without exacerbations (€3892). P. aeruginosa infection increased management costs by US$31,551 to US$56,499, as reported in two US studies, with hospitalization being the main cost driver., Conclusions: The current literature suggests that the economic burden of bronchiectasis in society is significant. Hospitalization costs are the major driver behind these costs, especially in patients with frequent exacerbations. However, the true economic burden of bronchiectasis is likely to be underestimated because most studies were retrospective, used ICD-9-CM coding to identify patients, and often ignored outpatient burden and cost. We present a conceptual framework to facilitate a more comprehensive assessment of the true burden of bronchiectasis for individuals, healthcare systems and society.

Purpose: The objectives of this study were to analyze the characteristics of male and female patients hospitalized with acute exacerbation of chronic obstructive pulmonary disease (AE-COPD) during 2006-2014 according to the presence or absence of bronchiectasis and to study the factors associated with in-hospital mortality (IHM) in patients hospitalized with AE-COPD and concomitant bronchiectasis., Methods: We used the Spanish National Hospital Database to analyze patients admitted with AE-COPD as their primary diagnosis. Patients included in the study were stratified according to the presence or absence of bronchiectasis as their secondary diagnosis., Results: We identified 386,646 admissions for AE-COPD, of which 19,679 (5.09%) involved patients with concomitant bronchiectasis. When patients with and without bronchiectasis were compared, we observed that the incidence of infection by Pseudomonas aeruginosa was substantially higher in the former, as were the mean stay, cost, and percentage of readmissions, although IHM and comorbidity were lower. The course of patients with AE-COPD and bronchiectasis was characterized by a gradual increase in prevalence and mean age among men and no differences in prevalence or lower mean age in women. Mortality was 4.24% and 5.02% in patients with and without bronchiectasis, respectively, although significance was lost after a multivariate adjustment (OR 0.94; 95% CI, 0.88-1.01). The factors associated with IHM were older age, higher comorbidity, isolation of P. aeruginosa, mechanical ventilation and readmission., Conclusions: The prevalence of admission with AE-COPD and bronchiectasis increased in men but not in women during the study period. In patients hospitalized with AE-COPD, we did not find differences in mortality when comparing the presence and absence of bronchiectasis. The analysis of temporal trends revealed a significant reduction in mortality from 2006 to 2014 in male patients with COPD and concomitant bronchiectasis, but not among women. It is important to consider the factors associated with IHM such as age, comorbidity, isolation of P. aeruginosa, mechanical ventilation and readmission to better identify those patients who are at greater risk of dying during hospitalization., Competing Interests: The authors have declared that no competing interests exist.

Recent research suggests that bronchiectasis (BE) may be more common than previously believed and that comorbid chronic obstructive pulmonary disease (COPD) is widespread in this patient population. Little is known about the economic burden among patients with BE, and less is known about the burden among those with comorbid BE + COPD. A retrospective matched-cohort design and data from a US health-care claims repository were employed. From the source population comprising adults who had comprehensive medical/drug benefits for ≥1 day in 2013 (i.e. the referent year) and evidence of BE and/or COPD at any time from 2009 to 2013, patients with BE + COPD were age/sex-matched (1:1:1) to patients with BE only and patients with COPD only. For each matched subgroup, annualized levels of respiratory-related and all-cause health-care utilization and expenditures in 2013 were summarized. Source population included 679,679 patients; among those with BE ( n = 31,027), 50% had comorbid COPD. Mean (95% CI) annual levels of respiratory-related utilization and expenditures among matched patients with BE + COPD ( n = 11,685) were higher by 2.4-3.5 times versus patients with BE only and 2.0-2.5 times versus patients with COPD only: hospitalizations, 0.39 (0.37-0.41) versus 0.11 (0.09-0.12) and 0.16 (0.14-0.17); ambulatory encounters, 16.5 (16.1-16.9) versus 6.8 (6.6-7.0) and 8.2 (7.9-8.4); and total expenditures, US$15,685 (14,693-16,678) versus US$5605 (5059-6150) and US$6262 (5655-6868). Respiratory-related utilization and expenditures are high among patients with BE or COPD receiving medical care in US clinical practice and are especially high among those with comorbid BE + COPD receiving medical care, emphasizing the importance of identifying and treating this unique patient population. Funding for this research was provided by RespirTech to Policy Analysis Inc. (PAI).

Background: Knowing the cost of hospitalizations for exacerbation in bronchiectasis patients is essential to perform cost-effectiveness studies of treatments that aim to reduce exacerbations in these patients., Objectives: To find out the mean cost of hospitalizations due to exacerbations in bronchiectasis patients, and to identify factors associated with higher costs., Methods: Prospective, observational, multicenter study in adult bronchiectasis patients hospitalized due to exacerbation. All expenses from the patients' arrival at hospital to their discharge were calculated: diagnostic tests, treatments, transferals, home hospitalization, admission to convalescence centers, and hospitals' structural costs for each patient (each hospital's tariff for emergencies and 70% of the price of a bed for each day in a hospital ward)., Results: A total of 222 patients (52.7% men, mean age 71.8 years) admitted to 29 hospitals were included. Adding together all the expenses, the mean cost of the hospitalization was EUR 5,284.7, most of which correspond to the hospital ward (86.9%), and particularly to the hospitals' structural costs. The adjusted multivariate analysis showed that chronic bronchial infection by Pseudomonas aeruginosa, days spent in the hospital, and completing the treatment with home hospitalization were factors independently associated with a higher overall cost of the hospitalization., Conclusions: The mean cost of a hospitalization due to bronchiectasis exacerbation obtained from the individual data of each episode is higher than the cost per process calculated by the health authorities. The most determining factor of a higher cost is chronic bronchial infection due to P. aeruginosa, which leads to a longer hospital stay and the use of home hospitalization., (© 2018 S. Karger AG, Basel.)

Objective: To analyze changes in the incidence, diagnostic procedures, comorbidity, length of hospital stay (LOHS), costs and in-hospital mortality (IHM) for patients with bronchiectasis who were hospitalized in Spain over a 10-year period., Methods: We included all admissions for patients diagnosed with bronchiectasis as primary or secondary diagnosis during 2004-2013., Results: 282,207 patients were admitted to the study. After controlling for possible confounders, we observed a significant increase in the incidence of hospitalizations over the study period when bronchiectasis was a secondary diagnosis. When bronchiectasis was the primary diagnosis we observed a significant decline in the incidence. In all cases, this pathology was more frequent in males, and the average age and comorbidity increased significantly during the study period (p<0.001). When bronchiectasis was the primary diagnosis, the most frequent secondary diagnosis was Pseudomonas aeruginosa infection. When bronchiectasis was the secondary diagnosis, the most frequent primary diagnosis was COPD. IHM was low, tending to decrease from 2004 to 2013 (p<0.05). The average LOHS decreased significantly during the study period in both cases (p<0.001). The mean cost per patient decreased in patients with bronchiectasis as primary diagnosis, but it increased for cases of bronchiectasis as secondary diagnosis (p<0.001)., Conclusions: Our results reveal an increase in the incidence of hospital admissions for patients with bronchiectasis as a secondary diagnosis from 2004 to 2013, as opposed to cases of bronchiectasis as the primary diagnosis. Although the average age and comorbidity significantly increased over time, both IHM and average LOHS significantly decreased., Competing Interests: The authors have declared that no competing interests exist.

Objective: To establish the cost-effectiveness of long-term humidification therapy (LTHT) added to usual care for patients with moderate or severe chronic obstructive pulmonary disease or bronchiectasis., Methods: Resource usage in a 12-month clinical trial of LTHT was estimated from hospital records, patient diaries, and the equipment supplier. Health state utility values were derived from the St. Georges Respiratory Questionnaire (SGRQ) total score. All patients who remained in the trial for 12 months and who had at least 90 days of diary records were included (87 of 108)., Results: Clinical costs were NZ $3973 (95% confidence interval [CI] $1614-$6332) for the control group and NZ $3331 (95% CI $948-$6920) for the intervention group. The mean health benefit per patient was -6.9 SGRQ units (95% CI -13.0 to -7.2; P < 0.05) or +0.0678 quality-adjusted life-years (95% CI 0.001-0.135). With the intervention costing NZ $2059 annually, the mean cost per quality-adjusted life-year was NZ $20,902 (US $18,907) and the bootstrap median was NZ $19,749 (2.5th percentile -$40,923, 97.5th percentile $221,275). At a willingness-to-pay (WTP) threshold of NZ $30,000, the probability of cost-effectiveness was 61%, ranging from 49% to 72% as the cost of LTHT was varied by ±30%. At a WTP of NZ $20,000, the probability was 49% (range 34%-61%)., Conclusions: LTHT is moderately cost-effective for patients with moderate to severe chronic obstructive pulmonary disease or bronchiectasis at a WTP threshold that is acceptable for public funding of medicines in New Zealand. These findings must be interpreted with caution because of the modest size of the clinical study, necessary lack of blinding in the clinical trial, and uncertainty in estimating health state utility from the SQRQ., (Copyright © 2014 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Bronchiectasis is an abnormal permanent dilatation distortion and destruction of the airways with both pulmonary and extrapulmonary side-effects. The aim of the study was to find out the presenting features, aetiologies and socioeconomic factors in patients of bronchiectasis. It is a prospective observational study comprising 53 patients over aperiod of two years. Aetiologies were determined using Kuppuswamy's socioeconomic scale. Number of exacerbations and mortality were noted. The age ranged from 14 to 80 years (mean: 43.33 ± 16.37 years). There were 35 males (66%) and 18 females (34%). Clubbing was seen in 58% cases (n = 31); 11% patients (n = 6) had haemoptysis. Bilateral involvement was seen in 64% cases (n = 34). Allergic bronchopulmonary aspergillosis and post-tuberculous sequelae were the commonest causes (n = 12, 23% each). The range of household medical expenditure in these patients varied from 6% to 47%. Lower the Kuppuswamy scale poorer the follow-up (p-value < 0.05). Multiple exacerbations were seen in all classes of patients (p-value 0.09). Death occurred in 4 patients. It is concluded that bronchiectasis is a chronic illness with significant morbidity and socioeconomic implications. Lower the socio-economic scale, poorer the compliance of therapy.

Objective: Indigenous children in developed countries are at increased risk of chronic suppurative lung disease (CSLD), including bronchiectasis. We evaluated sociodemographic and medical factors in indigenous children with CSLD/bronchiectasis from Australia, United States (US), and New Zealand (NZ)., Methods: Indigenous children aged 0.5-8 years with CSLD/bronchiectasis were enrolled from specialist clinics in Australia (n = 97), Alaska (n = 41), and NZ (n = 42) during 2004-2009, and followed for 1-5 years. Research staff administered standardized parent interviews, reviewed medical histories and performed physical examinations at enrollment., Results: Study children in all three countries had poor housing and sociodemographic circumstances at enrollment. Except for increased household crowding, most poverty indices in study participants were similar to those reported for their respective local indigenous populations. However, compared to their local indigenous populations, study children were more often born prematurely and had both an increased frequency and earlier onset of acute lower respiratory infections (ALRIs). Most (95%) study participants had prior ALRI hospitalizations and 77% reported a chronic cough in the past year. Significant differences (wheeze, ear disease and plumbed water) between countries were present., Discussion: Indigenous children with CSLD/bronchiectasis from three developed countries experience significant disparities in poverty indices in common with their respective indigenous population; however, household crowding, prematurity and early ALRIs were more common in study children than their local indigenous population. Addressing equity, especially by preventing prematurity and ALRIs, should reduce risk of CSLD/bronchiectasis in indigenous children., (© 2013 Wiley Periodicals, Inc.)

Background: Representative population-based data on the epidemiology of bronchiectasis in Europe are limited. The aim of the present study was to investigate the current burden and the trends of bronchiectasis-associated hospitalizations and associated conditions in Germany in order to inform focused patient care and to facilitate the allocation of healthcare resources., Methods: The nationwide diagnosis-related groups hospital statistics for the years 2005-2011 were used in order to identify hospitalizations with bronchiectasis as any hospital discharge diagnosis according to the International Classification of Diseases, 10th revision, code J47, (acquired) bronchiectasis. Poisson log-linear regression analysis was used to assess the significance of trends. In addition, the overall length of hospital stay (LOS) and the in-hospital mortality in comparison to the nationwide overall mortality due to bronchiectasis as the primary diagnosis was assessed., Results: Overall, 61,838 records with bronchiectasis were extracted from more than 125 million hospitalizations. The average annual age-adjusted rate for bronchiectasis as any diagnosis was 9.4 hospitalizations per 100,000 population. Hospitalization rates increased significantly during the study period, with the highest rate of 39.4 hospitalizations per 100,000 population among men aged 75-84 years and the most pronounced average annual increases among females. Besides numerous bronchiectasis-associated conditions, chronic obstructive pulmonary disease (COPD) was most frequently found in up to 39.2% of hospitalizations with bronchiectasis as the primary diagnosis. The mean LOS was comparable to that for COPD. Overall, only 40% of bronchiectasis-associated deaths occurred inside the hospital., Conclusions: The present study provides evidence of a changing epidemiology and a steadily increasing prevalence of bronchiectasis-associated hospitalizations. Moreover, it confirms the diversity of bronchiectasis-associated conditions and the possible association between bronchiectasis and COPD. As the major burden of disease may be managed out-of-hospital, prospective patient registries are needed to establish the exact prevalence of bronchiectasis according to the specific underlying condition.

Background: Recent estimates suggest the prevalence of non-cystic fibrosis bronchiectasis (NCFB) may be increasing in the US. The objective of this study was to determine the current economic burden of NCFB compared with non-NCFB controls in the first year after diagnosis within a commercially enrolled US population., Methods: A retrospective matched cross-sectional case control (1:3) study design was used. Data were derived from MarketScan(®) Commercial Claims and Encounters Database, which captures all patient-level demographic data and all medical and pharmacy claims during the period 1 January 2005 to 31 December 2009. NCFB patients were identified using ICD-9 codes 494.0 and 494.1. Individuals with medical claims for cystic fibrosis or chronic obstructive pulmonary disease were excluded. Incremental burden of NCFB was estimated for overall and respiratory-related expenditures using multivariate regression models which adjusted for baseline characteristics and healthcare resource utilization. All demographic characteristics and economic outcomes were ascertained in 12 months before (baseline period) and 12 months after (follow-up) index event, which was defined as the first bronchiectasis-related medical event. Non-parametric bootstrap technique was used to calculate the 95 % confidence limits for the adjusted estimate. All costs are inflation-adjusted to a baseline year of 2009 using the consumer price index. All statistical tests were conducted using SAS 9.2 and STATA 12.0., Results: The study sample used for healthcare burden analyses had 9,146 cases and 27,438 matched controls. The majority of the sample was between the ages of 45-64 years old and 64 % were female. A greater proportion of cases than controls had an increase from baseline to follow-up in both total (49 vs 40 %) and respiratory-related costs (57 vs 25 %). The average increase in overall and respiratory-related costs compared with controls after adjusting for differences in baseline characteristics was US$2,319 (95 % CI 1,872-2,765) and US$1,607 (95 % CI 1,406-1,809), respectively. The primary driver for this increment was increase in outpatient visits of approximately 2 overall and 1.6 respiratory-related visits per patient per year, which translated to US$1,730 (95 % CI 1,332-2,127) and US$1,253 (95 % CI 1,097-1,408), respectively., Conclusion: This study found that the cost of managing NCFB in the first year within a commercially enrolled population may be burdensome. Compared with previously published estimates in the literature, the burden of NCFB may be also increasing.

Introduction: The global burden of disease due to bronchiectasis is high, disproportionately impacting developing countries and disadvantaged populations. Bronchiectasis, the destruction and dilation of airways, is due to a variety of causes and is characterized by a self-perpetuating cycle of airway inflammation, infection and obstruction that results in substantial morbidity and mortality. Although many therapies have been tested that address each of these three components, as well as the diseases that both cause and result from bronchiectasis, there have been few randomized, placebo-controlled trials., Areas Covered: In this review, current knowledge of the clinical features, pathophysiology and epidemiology of bronchiectasis among both adults and children is summarized. We discuss the quality and extent of evidence supporting current treatment strategies, focusing on therapies for which the strongest evidence of efficacy exists. We then identify key goals for future research on the causes and treatments of a variety of types of bronchiectasis., Expert Opinion: Significant advances in the prevention and treatment of bronchiectasis will require substantially improved understanding of the pathogenesis of this orphan disease. A concerted, global effort to coordinate studies of both the pathophysiology and potential treatments of bronchiectasis, in its many forms, could lead to substantial improvements in outcomes.

Background: Life-threatening complications and expensive posttransplantation medical care raises the issue whether lung transplantation (L-Tx) is cost effective. We studied, from a health care system perspective, the cost effectiveness (C/E) and cost utility (C/U) of L-Tx in a Canadian setting., Methods: An incremental C/E and C/U analysis of L-Tx, compared with the waiting list (WL), was carried out on 124 patients accepted into the Quebec L-Tx WL (1997-2001). Survival was presented in mean life-years (LYs). Utility, assessed with the standard gamble, was used in computing the quality-adjusted life-years (QALY). Different person-time experiences were simulated. Costs (95% confidence interval), in US dollars, were discounted at 5%., Results: The mean LYs and QALYs gained were 0.57 (0.36-0.78) and 0.62 (0.36-0.78), respectively. The cost per patient without Tx was 1102 dollars (856 dollars-1348 dollars) per month. The L-Tx program induced a screening cost of 6208 dollars per patient. The cost of the L-Tx procedure (n = 91) was 31,815 dollars (25,301 dollars-44,816 dollars). The post-Tx cost per month in the first, second, third, and fourth year was 1809 dollars dollars (1187 dollars-2446 dollars), 1060 dollars (703 dollars-1478 dollars), 1128 dollars (519 dollars-1735 dollars), and 626 dollars (495 dollars-758 dollars), respectively. The projected C/E and C/U of the L-Tx program, assessed on the basis of pre- and post-Tx extrapolations, reached 40,048 dollars and 46,631 dollars, respectively., Conclusions: L-Tx in this Canadian setting yielded a benefit in mean LYs and QALYs gained. Although the program is expensive, the C/E and C/U ratios for some patient groups prove to be an acceptable cost for the benefits observed.

Background: With the decrease in junior doctor hours, the advent of specialist registrars, and the availability of highly trained and experienced nursing personnel, the service needs of patients with chronic respiratory diseases attending routine outpatient clinics may be better provided by appropriately trained nurse practitioners., Methods: A randomised controlled crossover trial was used to compare nurse practitioner led care with doctor led care in a bronchiectasis outpatient clinic. Eighty patients were recruited and randomised to receive 1 year of nurse led care and 1 year of doctor led care in random order. Patients were followed up for 2 years to ensure patient safety and acceptability and to assess differences in lung function. Outcome measures were forced expiratory volume in 1 second (FEV(1)), 12 minute walk test, health related quality of life, and resource use., Results: The mean difference in FEV(1) was 0.2% predicted (95% confidence interval -1.6 to 2.0%, p=0.83). There were no significant differences in the other clinical or health related quality of life measures. Nurse led care resulted in significantly increased resource use compared with doctor led care (mean difference pound 1497, 95% confidence interval pound 688 to pound 2674, p<0.001), a large part of which resulted from the number and duration of hospital admissions. The mean difference in resource use was greater in the first year ( pound 2625) than in the second year ( pound 411)., Conclusions: Nurse practitioner led care for stable patients within a chronic chest clinic is safe and is as effective as doctor led care, but may use more resources.
