BACKGROUND Recent research has quantified the national health care resource use (HCRU) and health care expenditure (HCE) burden associated with adult asthma; however, estimates specific to school-aged children are more than 2 decades old. OBJECTIVE To estimate the national HCRU and HCEs attributable to asthma among school-aged children in the United States. METHODS This was a cross-sectional retrospective analysis of school-aged children (aged 6-17 years) in the nationally representative 2007-2013 Medical Expenditure Panel Survey. All-cause HCRU and HCEs of school-aged children with asthma were compared with school-aged children without asthma, controlling for sociodemographics and comorbidities. HCRU encounters included emergency department (ED) and outpatient visits, hospitalizations, and prescriptions. Expenditures included total, medical, ED, inpatient, outpatient, and pharmacy. Negative binomial regression analyses were used for HCRU and Heckman selection with logarithmic transformation, and smearing retransformation was used for HCEs. RESULTS There were 44,320 school-aged children of whom 5,890 had asthma. Children with asthma incurred a higher rate of all-cause annual ED visits (incidence rate ratio [IRR], 1.5; P < .001), hospitalizations (IRR, 1.4; P < .05), outpatient visits (IRR, 1.4; P < .001), and prescription drugs (IRR, 3.3; P < .001) compared with school-aged children without asthma. They incurred US

847 (2015 dollars) more annually in all-cause expenditures (P < .001). Private insurance and Medicaid paid the largest share of expenditures. Pharmacy and outpatient costs represented the largest proportion of total expenditures. On the basis of the nationally representative Medical Expenditure Panel Survey sample weights from 2013, the total annual HCEs attributable to asthma for school-aged children in the United States was US

5.92 billion (2015 dollars). CONCLUSION Childhood asthma continues to represent a prevalent and significant clinical and economic burden in the United States. More aggressive treatment and asthma management programs are needed to address this national financial and resource burden.

BACKGROUND The degree of asthma control among school-aged children (SAC) nationally is not well understood. OBJECTIVE The objective of this study was to characterize poor control among SAC (aged 6-17 years) in the United States. METHODS This was a retrospective analysis of the 2007-2013 Medical Expenditure Panel Survey. Indicators of poor control included exacerbation in previous year; use of >3 canisters of short-acting β-agonist (SABA) in 3 months; and asthma-specific (AS) emergency department (ED) or inpatient (IP) visits. Treatment indicators included daily controller medication and peak flow meter use. Negative binomial regression was used for health resource utilization (HRU); generalized linear models with log-link were used for health care expenditures. RESULTS There were 44,320 SAC, of whom 5,890 had asthma. The prevalence of poor control and treatment among SAC with asthma were as follows: exacerbation (59%), >3 canisters of SABA (4%), ED/IP visit (3%), daily controller (19%), peak flow (12%). In 2013, 3.4 million SAC had an asthma exacerbation and 200,000 had an AS ED/IP visit. SAC with asthma and an exacerbation had 18.9 times more annual AS ED visits (and 43.3 times more AS hospitalizations) than SAC with asthma but no exacerbation. SAC with asthma and an indicator of poor control incurred greater annual all-cause expenditures than SAC without asthma (

3,063 (ED/IP visit). Use of daily controller medication was low even among SAC with poor control (27% to 61%). CONCLUSION Renewed and vigilant asthma management and treatment is necessary to mitigate the current and long-term public health effects and expenditures associated with poor asthma control.

Background The Epidemiology and Natural History of Asthma: Outcomes and Treatment Regimens (TENOR I) study demonstrated high morbidity in patients with severe or difficult‐to‐treat asthma despite standard‐of‐care treatment. Objective We sought to determine the long‐term natural history of disease and outcomes in patients in TENOR I after more than a decade. Methods TENOR I was a multicenter observational study (2001‐2004) of 4756 patients with severe or difficult‐to‐treat asthma. TENOR II was a follow‐up study of TENOR I patients using a single cross‐sectional visit in 2013/2014. Overall, the sites participating in TENOR II originally enrolled 1230 patients in TENOR I. Clinical and patient‐reported outcomes were assessed, including very poorly controlled asthma based on National Heart, Lung, and Blood Institute guidelines. Results A total of 341 (27.7%) patients were enrolled in TENOR II and were representative of the TENOR I cohort. The most frequent comorbidities were rhinitis (84.0%), sinusitis (47.8%), and gastroesophageal reflux disease (46.3%). Mean percent predicted prebronchodilator and postbronchodilator FEV1 were 72.7% (SD, 21.4%) and 78.2% (SD, 20.7%), respectively. A total of 231 (72.9%) of 317 patients had positive test responses to 1 or more allergen‐specific IgEs. The mean blood eosinophil count was 200/&mgr;L (SD, 144/&mgr;L). Eighty‐eight (25.8%) patients experienced an asthma exacerbation in the prior 3 months requiring hospital attention, oral corticosteroids, or both. More than half (197/339 [58.1%]) had very poorly controlled asthma. Medication use suggested undertreatment. Conclusion TENOR II provides longitudinal data to characterize disease progression, heterogeneity, and severity in patients with severe or difficult‐to‐treat asthma. Findings show continued morbidity, including a high degree of comorbid conditions, allergic sensitization, exacerbations, and very poorly controlled asthma, including reduced lung function.
