RESUMEN
OBJECTIVE: Many authors examined the individual and societal impact of school absenteeism. Nevertheless, no empirical study has looked at the potential direct correlation between deliberate school absences and chronic illnesses in mid-adulthood. Our goal is to investigate any potential direct links between purposeful school absences and adult-onset asthma in middle age, as well as measure any associated costs of asthma. METHODS: Data were sourced from the National Longitudinal Survey of Youth 1979, a nationally representative survey. The outcome measure was self-reported asthma in mid-adulthood. School records of absenteeism from grades nine through twelve were the key explanatory variables. Logistic regressions were performed with controls for demographic, economic and health variables. Predicted probabilities from the regressions were used to quantify costs of adult-onset asthma in middle age due to intentional high school absenteeism. RESULTS: More years of chronic absenteeism in high school were associated with higher risk of adult-onset asthma in middle age. Four years of chronic absenteeism in high school during the late 1970s through the early 1980s could potentially have incurred between $817 million to $1 billion of asthma related costs in 2002, when these students were in their mid-adulthood. These potential asthma related costs due to high school absenteeism are sizeable considering that this high school cohort only accounted for six percent of the U.S. population. CONCLUSIONS: Reducing high school absenteeism could lower the incidence of adult-onset asthma in middle age, and its associated future economic burden.

BACKGROUND: Atopic dermatitis (AD) is a heterogeneous disease, associated with comorbidities, and high healthcare consumptions and costs. This study assessed the burden before and after treatment with dupilumab in adults with severe AD from 2018 to 2020, from the perspective of the Italian National Health Service (SSN). METHODS: From Fondazione Ricerca e Salute's administrative healthcare database (~5 million inhabitants/year), adults treated with dupilumab from 09/01/2018 to 31/12/2020 (index date) and a five-year lookback were identified. Age, sex and comorbidities at baseline, concomitant drugs, overnight hospitalizations, outpatient specialist services and direct costs charged to the SSN one year before/after index date were assessed. RESULTS: Of 337 adults treated with dupilumab (5.8x100,000 adult inhabitants/2019; 8.0x100,000/2020; 55% males; mean age 43±19), 68% (228/337) had ≥12-month follow-up available. Asthma was a common comorbidity (23% patients). Rates of patients treated with nearly all concomitant AD-related therapies reduced from 12 months before to 12 months after dupilumab treatment: antibacterials (from 59% to 50%), systemic corticosteroids (55% to 29%), antihistamines (54% to 38%) and cyclosporine (52% to 7%). A similar trend was observed among patients with asthma as comorbidity. Within 12 months before/after dupilumab, patients hospitalized halved from 14% to 7%, and patients receiving outpatient specialist care reduced from 72% to 65%. Annual mean direct total costs per patient treated with dupilumab charged to the SSN, net of dupilumab cost, were 1384 and 773, before and after dupilumab dispensation, respectively. CONCLUSIONS: Before dupilumab, observed patients had higher healthcare resource consumptions and direct SSN costs than after dupilumab.

INTRODUCTION: Contemporary data on the burden of chronic respiratory diseases in sub-Saharan Africa is limited. More so, their economic burden is not well described. This study aims to establish a chronic respiratory disease observatory for Africa. Specific study aims are (1) to describe the prevalence and determinants of asthma with a target to screen up to 4000 children and adolescents across four African cities; (2) to determine the prevalence and determinants of chronic obstructive pulmonary disease (COPD) with a target to screen up to 3000 adults (≥18 years) across five African cities; (3) to describe the disease burden by assessing the frequency and severity of symptoms and exacerbations, medication use, emergency healthcare utilisation and hospitalisation; and (4) to assess the economic burden and affordability of the medicines for these diseases. METHODS AND ANALYSIS: Surveys will be conducted in schools to identify children and adolescents with asthma using the Global Asthma Network screening questionnaire in Ghana, Nigeria, the Democratic Republic of Congo, and Uganda. Community surveys will be conducted among adults using an adapted version of the Burden of Obstructive Lung Disease Questionnaire to identify persons with COPD symptoms in Nigeria, Burkina Faso, Mozambique, Rwanda, and Sierra Leone. Fractional exhaled nitric oxide and pre-bronchodilator and post-bronchodilator spirometry will be done for children with asthma or asthma symptoms and for all adult participants. Children and adults with respiratory symptoms or diagnoses will complete the health economic questionnaires. Statistical analysis will involve descriptive and analytical statistics to determine outcomes. ETHICS AND DISSEMINATION: Ethical approval has been obtained from participating institutions. This study's results will inform deliberations at the United Nations General Assembly high-level meeting on non-communicable diseases in 2025. The results will be shared through academic conferences and journals and communicated to the schools and the communities.

This research aimed to examine the effectiveness of artificial intelligence applications in asthma and chronic obstructive pulmonary disease (COPD) outpatient treatment support in terms of patient health and public costs. The data obtained in the research using semiotic analysis, content analysis and trend analysis methods were analyzed with strengths, weakness, opportunities, threats (SWOT) analysis. In this context, 18 studies related to asthma, COPD and artificial intelligence were evaluated. The strengths of artificial intelligence applications in asthma and COPD outpatient treatment stand out as early diagnosis, access to more patients and reduced costs. The points that stand out among the weaknesses are the acceptance and use of technology and vulnerabilities related to artificial intelligence. Opportunities arise in developing differential diagnoses of asthma and COPD and in examining prognoses for the diseases more effectively. Malicious use, commercial data leaks and data security issues stand out among the threats. Although artificial intelligence applications provide great convenience in the outpatient treatment process for asthma and COPD diseases, precautions must be taken on a global scale and with the participation of international organizations against weaknesses and threats. In addition, there is an urgent need for accreditation for the practices to be carried out in this regard.

BACKGROUND: Asthma, a chronic respiratory disease, is associated with high economic burden. This study estimates per-worker medical and incremental medical costs associated with treated asthma by socioeconomic and demographic characteristics, industries, medical events, and sources of payments for workers aged ≥18 years. METHODS: We analyzed Medical Expenditure Panel Survey data from 2018 to 2020 to assess medical costs for treated asthma among workers using the International Classification of Diseases, Tenth Revision, Clinical Modification code for asthma (J45). We used two-part regression models to estimate medical and incremental medical costs controlling for covariates. All results are adjusted for inflation and presented in 2022 US dollar values. RESULTS: An estimated annual average of 8.2 million workers out of 176 million had at least one medical event associated with treated asthma. The annualized estimated per-worker incremental medical costs for those with treated asthma was $457 and was highest among: those in the age group of 35-44 years ($534), in the western region ($768), of Hispanic ethnicity ($693), employed in the utility and transportation industries ($898), males ($650), and for inpatient admissions ($754). The total annualized medical costs of treated asthma was $21 billion and total of incremental medical costs was $3.8 billion. CONCLUSION: Findings of higher incremental medical costs for treated asthma among workers in certain socioeconomic, demographic, and industry groups highlight the economic benefit of prevention and early intervention to reduce morbidity of asthma in working adults. Our results suggest that the per-person incremental medical costs of treated asthma among workers are lower than that for all US adults.

Introduction: Asthma is a chronic condition with a high prevalence and cost of care among children and adolescents. While previous research described the association of sociodemographic factors with childhood asthma prevalence, there is limited knowledge of these factors' association with medical expenditures. In this study, we examined disparities in treated asthma prevalence and medical expenditures among US children and adolescents. Methods: Using nationally representative data from the 2016-2021 Medical Expenditures Panel Survey, we conducted a cross-sectional study of 2,365 children and adolescents (aged 0-17 y) with treated asthma compared with 40,497 children and adolescents without treated asthma. Treated asthma was defined as whether the child or adolescent had a medical event (emergency department visit, hospital inpatient stay, hospital outpatient visit, office-based medical visit, home health, and/or prescribed medicines) due to asthma. We controlled for sociodemographic factors of race and ethnicity, age, sex, health insurance coverage, family poverty status, and census region. We used 2-part models and generalized linear models to estimate annual per-person incremental medical expenditures associated with asthma. Results: Children and adolescents with treated asthma were more likely than those without treated asthma to be non-Hispanic Black or Hispanic, male, and publicly insured. Children and adolescents with treated asthma had $3,362.56 in additional annual medical expenditures, of which $174.06 was out-of-pocket, compared with children and adolescents without treated asthma. The additional expenditures included $955.96 for prescribed medicines, $151.52 for emergency department visits, and $858.17 for office-based medical visits. Non-Hispanic Black children with treated asthma had significantly lower total ($2,721.28) and office-based visit expenditures ($803.19) than non-Hispanic White children with treated asthma. Conclusion: Disparities among children and adolescents in the US persist in treated asthma prevalence and associated medical expenditures by sociodemographic factors.

Benralizumab, a monoclonal antibody targeting IL-5 receptors, reduces exacerbations and oral corticosteroid requirements for severe, uncontrolled eosinophilic asthma. In Japan, geographic disparities in asthma outcomes suggest differential prescribing and access. This study aimed to quantify regional prescribing variations for benralizumab nationwide. Using Japan's National Database (NDB) of insurance claims (2009-2019), benralizumab standardized claim ratios (SCRs) were calculated for 47 prefectures. Correlations between SCRs and other biologics' SCRs, economic variables like average income, and physician densities were evaluated through univariate analysis and multivariate regressions. Income-related barriers to optimal prescribing were examined. Wide variation emerged in benralizumab SCRs, from 40.1 to 184.2 across prefectures. SCRs strongly correlated with omalizumab (r = 0.61, p < 0.00001) and mepolizumab (r = 0.43, p = 0.0024). Average monthly income also positively correlated with benralizumab SCRs (r = 0.45, p = 0.0016), whereas lifestyle factors were insignificant. Respiratory specialist density modestly correlated with SCRs (r = 0.29, p = 0.047). In multivariate regressions, average income remained the most robust predictor (B = 0.74, p = 0.022). Benralizumab SCRs strongly associate with income metrics more than healthcare infrastructure/population factors. Many regions show low SCRs, constituting apparent prescribing gaps. Access barriers for advanced asthma therapies remain inequitable among Japan's income strata. Addressing affordability alongside specialist allocation can achieve better prescribing quality and asthma outcomes.

BACKGROUND: Herpes zoster (HZ) is a painful condition caused by reactivation of the varicella-zoster virus. The objectives of this study were to compare HZ incidence in adults with asthma versus adults without asthma and to compare healthcare resource use as well as direct costs in adults with HZ and asthma versus adults with asthma alone in the USA. METHODS: This retrospective longitudinal cohort study included adults aged ≥18 years across the USA. Patients were identified from Optum's deidentified Clinformatics Data Mart Database, an administrative claims database, between 1 October 2015 and 28 February 2020, including commercially insured and Medicare Advantage with part D beneficiaries. Cohorts of patients with and without asthma, and separate cohorts of patients with asthma and HZ and with asthma but not HZ, were identified using International Classification of Diseases 10th Revision, Clinical Modification codes. HZ incidence, healthcare resource use and costs were compared, adjusting for baseline characteristics, between the relevant cohorts using generalised linear models. RESULTS: HZ incidence was higher in patients with asthma (11.59 per 1000 person-years) than patients without asthma (7.16 per 1000 person-years). The adjusted incidence rate ratio (aIRR) for HZ in patients with asthma, compared with patients without asthma, was 1.34 (95% CI 1.32 to 1.37). Over 12 months of follow-up, patients with asthma and HZ had more inpatient stays (aIRR 1.11; 95% CI 1.02 to 1.21), emergency department visits (aIRR 1.26; 95% CI 1.18 to 1.34) and outpatient visits (aIRR 1.19; 95% CI 1.16 to 1.22), and direct healthcare costs that were US dollars ($) 3058 (95% CI $1671 to $4492) higher than patients with asthma without HZ. CONCLUSION: Patients with asthma had a higher incidence of HZ than those without asthma, and among patients with asthma HZ added to their healthcare resource use and costs.

OBJECTIVE: To estimate the cost of paediatric asthma from a UK National Health Service (NHS) and societal perspective and explore determinants of these costs. DESIGN: Cost analysis based on data from a large clinical trial between 2017 and 2019. Case report forms recorded healthcare resource use and productivity losses attributable to asthma over a 12-month period. These were combined with national unit cost data to generate estimates of health service and indirect costs. SETTING: Asthma clinics in primary and secondary care in England and Scotland. MAIN OUTCOME MEASURES: Cost per asthma attack stratified by highest level of care received. Total annual health service and indirect costs. Modelled effect of sex, age, severity, number of attacks and adherence on total annual costs. RESULTS: Of 506 children included in the analysis, 252 experienced at least one attack. The mean (SD) cost per attack was £297 (806) (median £46, IQR 40-138) and the mean total annual cost to the NHS was £1086 (2504) (median £462, IQR 296-731). On average, children missed 6 days of school and their carers missed 13 hours of paid work, contributing to a mean annual indirect cost of £412 (879) (median £30, IQR 0-477). Health service costs increased significantly with number of attacks and participant age (>11 years). Indirect costs increased with asthma severity and number of attacks but were found to be lower in older children. CONCLUSIONS: Paediatric asthma imparts a significant economic burden on the health service, families and society. Efforts to improve asthma control may generate significant cost savings. TRIAL REGISTRATION NUMBER: ISRCTN 67875351.

OBJETIVO: Determinar la carga económica anual del asma, desde una perspectiva institucional y con base en la clasificación recomendada por GINA, en una cohorte retrospectiva de adultos atendidos en el Instituto Nacional de Enfermedades Respiratorias (INER) de México. MÉTODOS: Estudio observacional, longitudinal y retrospectivo, llevado a cabo a partir de la información recabada de 247 pacientes femeninas con asma. Se estimaron los costos directos anuales: visitas, pruebas de laboratorio, tratamiento farmacológico y de las crisis o exacerbaciones, para determinar la carga anual de la enfermedad desde una perspectiva institucional, y según la clasificación de la Iniciativa Global para el Asma. RESULTADOS: El costo promedio anual fue de $43,813,92, que aumentó en relación con la necesidad de aumento de dosis de corticoides inhalados y beta-agonistas de acción prolongada. El costo promedio de la consulta médica fue de $2004.57, $982.82 por gestión de crisis y $2645.95 por pruebas de laboratorio. El tratamiento farmacológico representó la principal carga económica, con un costo promedio anual de $38,180.58. CONCLUSIONES: Los resultados resaltan una carga económica del asma estimada en un costo anual por paciente de $43,813.92 MXN (DE=93,348.85), en el contexto del tercer nivel de atención en el sistema de salud público mexicano. La gravedad del asma, los tratamientos y los biológicos fueron los principales factores que aumentaron los costos directos de la atención.
OBJECTIVE: Determine the annual economic burden of the disease from an institutional perspective and based on GINA's recommended classification in a retrospective cohort of adults treated at Instituto Nacional de Enfermedades Respiratorias (INER) of Mexico City. METHODS: A retrospective, longitudinal observational study comprised by data from 247 female asthma patients, annual direct costs were estimated including: visits, laboratory tests, pharmacological treatment and management of crisis or exacerbations, to determine the annual burden of the disease from an institutional perspective and according to Global Initiative for Asthma classification. RESULTS: The average annual cost was $43,813.92, which increased in relation to the need of inhaled corticosteroids and long-acting beta agonists dosage increase. The average doctor's appointment cost was $2,004.57, $982.82 for crisis management and $2,645.95 for laboratory testing. Pharmacological treatment represented the main economic burden with an annual average cost of $38,180.58. CONCLUSIONS: The results highlight an economic burden of asthma estimated at an annual cost per patient of $43,813.92 MXN (SD=93,348.85) in the context of the third level of care in the Mexican public health system. The asthma severity and treatments such as biologics were the main factors that increased direct costs of care.

OBJECTIVE: To compare health outcomes and costs given in the emergency department (ED) and walk-in clinics for ambulatory children presenting with acute respiratory diseases. DESIGN: A retrospective cohort study. SETTING: This study was conducted from April 2016 to March 2017 in one ED and one walk-in clinic. The ED is a paediatric tertiary care centre, and the clinic has access to lab tests and X-rays. PARTICIPANTS: Inclusion criteria were children: (1) aged from 2 to 17 years old and (2) discharged home with a diagnosis of upper respiratory tract infection (URTI), pneumonia or acute asthma. MAIN OUTCOME MEASURES: The primary outcome measure was the proportion of patients returning to any ED or clinic within 3 and 7 days of the index visit. The secondary outcome measures were the mean cost of care estimated using time-driven activity-based costing and the incidence of antibiotic prescription for URTI patients. RESULTS: We included 532 children seen in the ED and 201 seen in the walk-in clinic. The incidence of return visits at 3 and 7 days was 20.7% and 27.3% in the ED vs 6.5% and 11.4% in the clinic (adjusted relative risk at 3 days (aRR) (95% CI) 3.17 (1.77 to 5.66) and aRR at 7 days 2.24 (1.46 to 3.44)). The mean cost (95% CI) of care (CAD) at the index visit was $C96.68 (92.62 to 100.74) in the ED vs $C48.82 (45.47 to 52.16) in the clinic (mean difference (95% CI): 46.15 (41.29 to 51.02)). Antibiotic prescription for URTI was less common in the ED than in the clinic (1.5% vs 16.4%; aRR 0.10 (95% CI 0.03 to 0.32)). CONCLUSIONS: The incidence of return visits and cost of care were significantly higher in the ED, while antibiotic use for URTI was more frequent in the walk-in clinic. These data may help determine which setting offers the highest value to ambulatory children with acute respiratory conditions.

INTRODUCTION: Definitions of moderate asthma exacerbation have been inconsistent, making their economic burden difficult to assess. An algorithm to accurately identify moderate exacerbations from claims data is needed. METHODS: A retrospective cohort study of Reliant Medical Group patients aged ≥18 years, with ≥1 prescription claim for inhaled corticosteroid/long-acting ß2-agonist, and ≥1 medical claim with a diagnosis code for asthma was conducted. The objective was to refine current algorithms to identify moderate exacerbations in claims data and assess the refined algorithm's performance. Positive and negative predictive values (PPV and NPV) were assessed via chart review of 150 moderate exacerbations events and 50 patients without exacerbations. Sensitivity analyses assessed alternative algorithms and compared healthcare resource utilization (HRU) between algorithm-identified patients (claims group) and those confirmed by chart review (confirmed group) to have experienced a moderate exacerbation. RESULTS: Algorithm-identified moderate exacerbations were: visit of ≤1 day with an asthma exacerbation diagnosis OR visit of ≤1 day with selected asthma diagnoses AND ≥1 respiratory pharmacy claim, excluding systemic corticosteroids, within 14 days after the first claim. The algorithm's PPV was 42%; the NPV was 78%. HRU was similar for both groups. CONCLUSION: This algorithm identified potential moderate exacerbations from claims data; however, the modest PPV underscores its limitations in identifying moderate exacerbations, although performance was partially due to identification of previously unidentified severe exacerbations. Application of this algorithm in future claims-based studies may help quantify the economic burden of moderate and severe exacerbations in asthma when an algorithm identifying severe exacerbations is applied first.

INTRODUCTION: Despite adherence to inhaled corticosteroid/long-acting ß2-agonist (ICS/LABA) therapy, many patients with asthma experience moderate exacerbations. Data on the impact of moderate exacerbations on the healthcare system are limited. This study assessed the frequency and economic burden of moderate exacerbations in patients receiving ICS/LABA. METHODS: Retrospective, longitudinal study analyzed data from Optum's de-identified Clinformatics® Data Mart Database recorded between October 1, 2015, and December 31, 2019. Eligibility criteria included patients ≥18 years of age with ≥1 ICS/LABA claim and ≥1 medical claim for asthma in the 12 months pre-index (first ICS/LABA claim). Primary objectives included describing moderate exacerbation frequency, and associated healthcare resource utilization (HRU) and costs. A secondary objective was assessing the relationship between moderate exacerbations and subsequent risk of severe exacerbations. Patients were stratified by moderate exacerbation frequency in the 12 months post index. Moderate exacerbations were identified using a newly developed algorithm. RESULTS: In the first 12 months post index 61.6% of patients experienced ≥1 moderate exacerbation. Mean number of asthma-related visits was 4.1 per person/year and median total asthma-related costs was $3544. HRU and costs increased with increasing exacerbation frequency. Outpatient and inpatient visits accounted for a similar proportion of these costs. Moderate exacerbations were associated with an increased rate and risk of future severe exacerbations (incidence rate ratio, 1.56; hazard ratio, 1.51 [both p < 0.001]). CONCLUSIONS: This study highlighted that a high proportion of patients continue to experience moderate exacerbations despite ICS/LABA therapy and subsequently experience increased economic burden and risk of future severe exacerbations.

BACKGROUND: Poor adherence to asthma and chronic obstructive pulmonary disease maintenance therapies impairs health outcomes. Proven and cost-effective programs to promote adherence and persistence are not yet in regular widespread use. Implementation costs are a potential barrier to uptake of such programs. OBJECTIVE: We undertook a systematic literature review and narrative synthesis of studies investigating the cost-effectiveness of treatment adherence-promoting programs or that determined their impact on health care budget directly or via health care resource use (HCRU). METHODS: We identified relevant publications using Medline and PreMEDLINE (PubMed), Embase (Embase.com, Elsevier), and EconLit for publications between January 2000 and July 2021. We also searched clinical trial databases and selected conference proceedings. RESULTS: Of 1,910 potentially relevant articles, 26 met prespecified inclusion criteria and underwent data extraction. Eleven reported a direct assessment of adherence, 15 included economic evaluations, and 17 described HCRU. None included an analysis of biologic medication use. When they were studied, interventions were often found to be highly cost-effective, with dominant incremental cost-effectiveness ratios in some cases. Reductions in direct costs and HCRU (health care visits, hospital admissions, and/or the use of medications, including add-on/reliever treatment and antibiotics) were frequently reported. Reported use of maintenance treatments improved in some studies. Counseling and/or digitally informed programs were used in all cases in which favorable outcomes were observed. CONCLUSIONS: Adherence-promoting interventions are mostly cost-effective and often result in reduced HCRU and associated costs. Multidisciplinary care involving one-to-one advice and digitally enhanced communications appear to offer the greatest benefit.

BACKGROUND: Tailoring asthma interventions based on biomarkers could substantially impact the high cost associated with asthma morbidity. For policymakers, the main concern is the economic impact of adopting this technology, especially in developing countries. This study evaluates the budget impact of asthma management using sputum eosinophil counts in Colombia patients between 4 and 18 years of age. METHODS: A budget impact analysis was performed to evaluate the potential financial impact of sputum eosinophil counts (EO). The study considered a 5-year time horizon and the Colombian National Health System perspective. The incremental budget impact was calculated by subtracting the cost of the new treatment, in which EO is reimbursed, from the cost of the conventional therapy without EO (management based on clinical symptoms (with or without spirometry/peak flow) or asthma guidelines (or both), for asthma-related). Univariate one-way sensitivity analyses were performed. RESULTS: In the base-case analysis, the 5-year costs associated with EO and no-EO were estimated to be US$ 532.865.915 and US$ 540.765.560, respectively, indicating savings for Colombian National Health equal to US$ 7.899.645, if EO is adopted for the routine management of patients with persistent asthma. This result was robust in univariate sensitivity one-way analysis. CONCLUSION: EO was cost-saving in guiding the treatment of patients between 4 and 18 years of age with persistent asthma. Decision-makers in our country can use this evidence to improve clinical practice guidelines, and it should be replicated to validate their results in other middle-income countries.

BACKGROUND: The economic burden of severe asthma and severe uncontrolled asthma (SUA) is significant. Updated assessments of health care resource utilization (HCRU) and cost are needed given the increase in treatment options and updates to guidelines in recent years. OBJECTIVE: To describe all-cause and asthma-related HCRU and costs among patients with SUA vs patients with nonsevere asthma in the United States using real-world data. METHODS: MarketScan administrative claims databases were used to select adults with persistent asthma for this retrospective analysis between January 1, 2013, and December 31, 2019. Asthma severity status was defined using the Global Initiative for Asthma step 4/5 criteria (index is the earliest date qualifying patients as severe or randomly assigned for nonsevere patients). Patients with SUA were a subset of the severe cohort meeting the following criteria: those who were hospitalized with asthma as the primary diagnosis or had at least 2 emergency department or outpatient visits with an asthma diagnosis and a steroid burst within 7 days. HCRU, costs (allcause and asthma-related defined as medical claims with an asthma diagnosis and pharmacy claims for asthma treatment), work loss, and indirect costs due to absenteeism and short-term disability (STD) were compared between patients with SUA, severe, and nonsevere asthma. Outcomes were reported during a fixed 12-month post-index period using chi-square and t-tests where appropriate. RESULTS: 533,172 patients with persistent asthma were identified (41.9% [223,610]) severe and 58.1% [309,562] nonsevere). Of the severe patients, 17.6% (39,380) had SUA. The mean (SD) all-cause total health care costs were significantly higher in patients with SUA ($23,353 [$40,817]) and severe asthma ($18,554 [$36,147]) compared with those with nonsevere asthma ($16,177 [$37,897], P < 0.001 vs nonsevere asthma). The results were consistent for asthma-related costs. In addition, although patients with severe asthma made up 41.9% of the total study population, they contributed disproportionately higher costs (60.5%) to the total asthma-related direct costs, with the effect more evident among patients with SUA (7.4% of study population contributed 17.7% of the total asthma-related costs). For the subset of patients with asthma with workplace absenteeism, patients with SUA lost more time from work (259.3 vs 236.2 hours lost, P = 0.002; 7.8 vs 5.3 STD days, P < 0.001), and had higher corresponding indirect costs ($5,944 vs $5,415, P = 0.002 for absenteeism related; $856 vs $582, P < 0.001 for STD related) compared with patients with nonsevere asthma. CONCLUSIONS: Patients with SUA have significantly higher asthma-related economic burden compared with patients with nonsevere asthma and contribute a disproportionally higher percentage of asthma-related costs.

Importance: Structural racism has been implicated in the disproportionally high asthma morbidity experienced by children living in disadvantaged, urban neighborhoods. Current approaches designed to reduce asthma triggers have modest impact. Objective: To examine whether participation in a housing mobility program that provided housing vouchers and assistance moving to low-poverty neighborhoods was associated with reduced asthma morbidity among children and to explore potential mediating factors. Design, Setting, and Participants: Cohort study of 123 children aged 5 to 17 years with persistent asthma whose families participated in the Baltimore Regional Housing Partnership housing mobility program from 2016 to 2020. Children were matched to 115 children enrolled in the Urban Environment and Childhood Asthma (URECA) birth cohort using propensity scores. Exposure: Moving to a low-poverty neighborhood. Main Outcomes: Caregiver-reported asthma exacerbations and symptoms. Results: Among 123 children enrolled in the program, median age was 8.4 years, 58 (47.2%) were female, and 120 (97.6%) were Black. Prior to moving, 89 of 110 children (81%) lived in a high-poverty census tract (>20% of families below the poverty line); after moving, only 1 of 106 children with after-move data (0.9%) lived in a high-poverty tract. Among this cohort, 15.1% (SD, 35.8) had at least 1 exacerbation per 3-month period prior to moving vs 8.5% (SD, 28.0) after moving, an adjusted difference of -6.8 percentage points (95% CI, -11.9% to -1.7%; P = .009). Maximum symptom days in the past 2 weeks were 5.1 (SD, 5.0) before moving and 2.7 (SD, 3.8) after moving, an adjusted difference of -2.37 days (95% CI, -3.14 to -1.59; P < .001). Results remained significant in propensity score-matched analyses with URECA data. Measures of stress, including social cohesion, neighborhood safety, and urban stress, all improved with moving and were estimated to mediate between 29% and 35% of the association between moving and asthma exacerbations. Conclusions and Relevance: Children with asthma whose families participated in a program that helped them move into low-poverty neighborhoods experienced significant improvements in asthma symptom days and exacerbations. This study adds to the limited evidence suggesting that programs to counter housing discrimination can reduce childhood asthma morbidity.
