Barne M. Gaps in asthma diagnosis and treatment in low- and middle-income countries. FRONTIERS IN ALLERGY 2023; 4:1240259. [PMID: 37937199 PMCID: PMC10627233 DOI: 10.3389/falgy.2023.1240259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 10/02/2023] [Indexed: 11/09/2023] Open
Abstract
Low- and middle-income countries (LMICs) contribute to a major proportion of asthma morbidity and mortality globally, even though the prevalence is higher in high income countries. Mortality due to asthma is avoidable and patients should be able to live a near normal life. There are factors that influence overall disease prevalence and poor health outcomes due to asthma in LMICs. This article summarizes the gaps in asthma diagnosis and management in LMICs. The gaps are diverse. Each challenge needs to be addressed through policy decisions, upgrade of infrastructure, knowledge and skills for early diagnosis and correct management among health care providers, both clinicians and paramedics. Healthcare accessibility and affordability are genuine challenges, and the public healthcare system needs to be geared up to address these at primary and tertiary levels. Mass education of the population through national level government initiatives is needed to help bridge the sociocultural gaps.

Abstract
OBJECTIVE Asthma is a leading cause of emergency department (ED) visits and hospitalizations in children, though many could be prevented. Our study objective was to identify factors from the published literature that are associated with future hospitalization for asthma beyond 30 days following an initial asthma ED visit. DATA SOURCES We searched CINAHL, CENTRAL, MEDLINE, and Embase for all studies examining factors associated with asthma-related hospitalization in children from January 1, 1992 to February 7, 2022.Selecting Studies: All citations were reviewed independently by two reviewers and studies meeting inclusion criteria were assessed for risk of bias. Data on all reported variables were extracted from full text and categorized according to identified themes. Where possible, data were pooled for meta-analysis using random effects models. RESULTS Of 2262 studies, 68 met inclusion criteria. We identified 28 risk factors and categorized these into six themes. Factors independently associated with future hospitalization in meta-analysis include: exposure to environmental tobacco smoke (OR = 1.94 95%CI 0.67-5.61), pets exposure (OR = 1.67 95%CI 1.17-2.37), and previous asthma hospitalizations (OR = 3.47 95% CI 2.95-4.07). Additional related factors included previous acute care visits, comorbid health conditions (including atopy), allergen exposure, severe-persistent asthma phenotype, inhaled steroid use prior to ED visit, poor asthma control, higher severity symptoms at ED presentation, warmer season at admission, longer length of stay or ICU admission, and African-American race/ethnicity. CONCLUSIONS We identified multiple factors that are consistently associated with future asthma hospitalization in children and could be used to identify those who would benefit from targeted preventative interventions.

Abstract
Purpose To describe the socio-demographics and clinical characteristics of children in a pulmonology clinic or admitted to a children’s hospital with well-controlled and poorly controlled asthma, and to assess caregiver knowledge of asthma pathogenesis, treatment, and self-management. Patients and Methods A cohort of 132 children aged 2–18 years and their caregivers seen in a pediatric pulmonology clinic with a diagnosis of asthma (n=112) or admitted to the hospital with a diagnosis of asthma exacerbation (n=20) were invited to participate in a cross-sectional study. Caregivers completed a survey, which healthcare providers then used to tailor asthma education to the patient and caregiver. Two-tail t-tests and Chi-square tests were used to compare demographics and clinical characteristics of children with well-controlled vs poorly controlled asthma. Results Of 132 children, 111 children in this cohort had poorly controlled asthma (84%). Medicaid insurance was associated with poorly controlled asthma versus well-controlled asthma (63% vs 35% p=0.01). Asthma action plans (AAP) had previously been given to 113 caregivers (86%), but caregivers of children with both well-controlled and poorly controlled asthma still reported misconceptions about asthma pathology and management, such as stopping daily medications when asthma is controlled. Conclusion This study contributes to the existing evidence that socio-demographics have a significant impact on asthma prevalence and proper management. Our study suggests that caregivers of children with asthma need comprehensive asthma education beyond the AAP focusing on asthma-related misconceptions.

Abstract
BACKGROUND Prior studies investigating the effect of socioeconomic status (SES) on asthma health care outcomes have been heterogeneous in the populations studied and methodologies used. OBJECTIVE We sought to systematically synthesize evidence investigating the impact of SES on asthma health care utilization, exacerbations, and mortality. METHODS We searched Embase, Medline, and Web of Science for studies reporting differences in primary care attendance, exacerbations, emergency department attendance, hospitalization, ventilation/intubation, readmission, and asthma mortality by SES. Study quality was assessed using the Newcastle Ottawa Scale, and meta-analyses were conducted using random-effects models. We conducted several prespecified subgroup analyses, including by health care system (insurance based vs universal government funded) and time period (before vs after 2010). RESULTS A total of 61 studies, comprising 1,145,704 patients, were included. Lower SES was consistently associated with increased secondary health care utilization including emergency department attendance (odds ratio [OR], 1.61; 95% confidence interval [CI], 1.40-1.84), hospitalization (OR, 1.63; 95% CI, 1.34-1.99), and readmission (OR, 1.31; 95% CI, 1.19-1.44). Substantial associations were also found between SES and ventilation/intubation (OR, 1.76; 95% CI, 1.13-2.73), although there was no association with primary care attendances (OR, 0.79; 95% CI, 0.51-1.24). We found evidence of borderline significance for increased exacerbations (OR, 1.18; 95% CI, 0.98-1.42) and mortality (OR, 1.12; 95% CI, 0.92-1.37) among more deprived groups. There was no convincing evidence that disparities were associated with country-level health care funding models or that disparities have narrowed over time. CONCLUSIONS Patients with a lower SES have substantially increased secondary care health care utilization. We found evidence suggestive of increased exacerbations and mortality risk, although CIs were wide. These disparities have been consistently reported worldwide, including within countries offering universally funded health care systems. Systematic review registration: CRD42020173544.

Abstract
INTRODUCTION The health and financial burden of mild-persistent asthma has been poorly investigated. OBJECTIVE Our aim was to compare the rate of hospital admissions that have occurred during the preceding year between children and adolescents with current mild-persistent (MP) and moderate-severe (MS) asthma. METHODS We screened children and adolescents with asthma at eight outpatient clinics. The inclusion criteria were asthma diagnosis, age from 6 to 18 years and follow-up with a physician during the preceding 6 months. Subjects answered standardized questionnaires and underwent spirometry. RESULTS We enrolled 220 MP and 102 MS asthmatic subjects. The proportion of subjects with HA during the preceding year was similar between MP and MS asthma groups (7% vs. 7%; p = .89). Symptoms score and the financial values spent by the family in the care of asthma were lower in MP asthma as compared with MS asthma group (asthma control questionnaire score 0.7 [0.3-1.0) vs. 2.0 [1.1-2.5]; p < .01) (asthma expenses in USD 13 [2-43] vs. 28 [10-83]; p < .01). The frequency of subjects using inhaled corticosteroids maintenance therapy was lower in the MP asthma group as compared with the MS asthma group (54% vs. 100%; p < .01). CONCLUSION We conclude that the frequency of hospital admissions that have occurred during the preceding year was similar between subjects with current MP and MS asthma. Symptoms score and the financial values spent by the family in the care of asthma were lower in the MP asthma group.

Abstract
BACKGROUND Asthma is a common chronic childhood illness and frequent cause of hospitalization. A decline in hospital admission rates was noted up to the 1990s, however, trends are not as clear since the turn of the century. This study aimed to assess the rates and regional differences of asthma admissions over more than two decades using the national Ministry of Health database, which registers data from all the hospitals. METHODS A retrospective cohort study, analysis of all pediatric asthma admissions, for Patients 1-14 years old, between 1996 and 2017 as recorded by the National Hospital Discharge Registry, was performed. Asthma admission rates were calculated per 1000 age adjusted residents, using the number of admission cases as the numerator, and age specific population size as the denominator. RESULTS The annual asthma hospitalization rate decreased in the entire pediatric population from 2.14 in 1996-0.89 in 2017. Children in the 1-4 year age group comprised most of the hospital admissions, and most of the decline was attributable to this age group. Significant differences in hospitalizations were found between different regions as well as differences in the rate of decline in asthma hospitalizations with the lowest admission rate in the Jerusalem district, highest in Haifa, northern and southern Israeli regions and the greatest rate of decline in the Tel-Aviv district. CONCLUSION This nationwide study, over more than two decades, shows clear regional differences in the rates of asthma admissions as well as regional differences in the rates of decline.

Abstract
INTRODUCTION This study assesses the associations of child salivary cotinine, parent-reported smoking, and child tobacco smoke exposure with the number of child healthcare visits and hospital admissions over a 6-month period. This study also assesses the relationships between participant characteristics and child cotinine. METHODS Longitudinal data were evaluated from a sample of 313 clinically ill children aged 0-9 years who lived with a smoker and presented to a pediatric emergency department or urgent care in 2016-2018. In 2020, cotinine measurements were log transformed, and Poisson and linear regression were performed. RESULTS The majority of the children came from low-income homes (66.1%) and had public insurance/self-pay (95.5%). Child cotinine concentrations ranged from 0.1 to 332.0 ng/mL (geometric mean=4.8 ng/mL, 95% CI=4.1, 5.5). Poisson regression results indicated that each 1-unit increase of log-cotinine concentration was associated with an increase in pediatric emergency department visits over a 6-month period after the baseline visit, with an adjusted RR of 1.16 (95% CI=1.01, 1.34). Each 1-unit increase of log-cotinine concentration was associated with an increase in the frequency of hospital admissions over the 6-month period, with an adjusted RR of 1.50 (95% CI=1.08, 2.09). No differences were found between parent-reported smoking or child tobacco smoke exposure and healthcare utilization. Linear regression results indicated that children who were younger (β= -0.227, p=0.049), were White (geometric mean=5.5 ng/mL), had a medical history of prematurity (geometric mean=8.1 ng/mL), and had a winter baseline visit (geometric mean=6.5 ng/mL) had higher cotinine concentrations. Children living in apartments (geometric mean=5.5 ng/mL) and multiunit homes (geometric mean=5.5 ng/mL) had higher cotinine concentrations than those in single-family homes (geometric mean=3.6 ng/mL). CONCLUSIONS Routine biochemical screening could identify children who are in need of intensive tobacco smoke exposure reduction interventions.

Abstract
BACKGROUND Maternal depression has been linked to health care use for asthma in cross-sectional or short-term follow-up studies of school-aged children. OBJECTIVE To examine whether increased or persistent maternal depressive symptoms over approximately 5 years are associated with severe asthma exacerbations or worse lung function in youth. METHODS A prospective study of 386 youth living in Puerto Rico, aged 6 to 14 years at a baseline visit and 9 to 20 years at a second visit, was performed. Our exposure of interest was change in persistence of maternal depressive symptoms, assessed at both visits using the Center for Epidemiologic Studies Depression Scale (CESD). Our outcomes of interest were change in percent predicted forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) between the first and second visits in all subjects, and ≥1 severe asthma exacerbation in the year before the second visit in subjects with asthma. RESULTS In a multivariable analysis, each 1-point increment in the CESD score was associated with decrements of 0.15% in percent predicted FEV1 (95% confidence interval [CI] = -0.28% to -0.01%; P = .03) and 0.10% in percent predicted FEV1/FVC (95% CI = -0.20% to 0.001%; P = .05) between visits, as well as with 1.03 times increased odds of ≥1 severe asthma exacerbation at the second visit (95% CI for odds ratio = 0.99 to 1.06, P = .09). In a multivariable analysis, the presence of maternal depressive symptoms (a CESD score ≥21 points) at the second visit or at both visits was significantly associated with 3.17 to 3.52 times increased odds of ≥1 severe asthma exacerbation in the year before the second visit. CONCLUSIONS Increasing or persistent maternal depressive symptoms over approximately 5 years are associated with worse lung function measures and severe asthma exacerbations among Puerto Rican youth, a high-risk population.

Abstract
INTRODUCTION Although evidence supports the use of intravenous magnesium sulfate (MS) in asthma exacerbations, MS continues to be considered a second-line drug for managing pediatric asthma exacerbations. This study aimed to evaluate the cost-utility of MS in asthma exacerbations. METHODS We used a decision tree model to estimate the cost-utility of MS compared to treatment without MS (control group) in children with asthma exacerbations. Cost data were obtained from a retrospective study from tertiary centers in Rionegro, Colombia, while utilities were collected from the literature. Probabilistic sensitivity analysis was carried out using the Monte Carlo technique with a simulation of a hypothetical cohort of 10 000 patients to generate expected cost utilities with 95% confidence intervals. We used a cost-effectiveness acceptability curve to evaluate the uncertainty surrounding the cost-utility of MS. RESULTS The model showed that MS had a lower total cost than the control group (US $1149 vs US $1598 average cost per patient) and higher quality-adjusted life years (0.60 vs 0.52 average per patient), showing dominance. The probability that MS provides a more cost-effective use of resources compared with standard therapy exceeds 99% for all willingness-to-pay thresholds. CONCLUSION Intravenous MS was less expensive and more effective than treatment without intravenous MS in children with asthma exacerbations. Our study provides evidence that should be used by decision-makers to improve clinical practice guidelines and should be replicated to validate its results in other middle-income countries.

Abstract
BACKGROUND Variation in emergency department (ED) management for asthma exacerbation leads to disparities in care. Current asthma severity scores are insufficient to be used for hospitalization decisions. OBJECTIVE To develop and internally validate an asthma predictive index for hospitalization (APIH) to guide practitioners in their admission decision for children with asthma exacerbations. METHODS Data were collected from 12,066 children between 5 and 18 years old diagnosed with asthma exacerbation in the ED. Epidemiologic findings, number of inhaled corticosteroid canisters, short-acting β-blocker canisters, oral steroids, coexisting atopy, family history of atopy, insurance, and prior asthma ED visits or hospitalizations were compared between patients hospitalized and discharged. We used univariate analysis and multivariate analysis to determine the best predictor variables for hospitalization. Our study internally validated the prediction index to estimate future performance of the prediction rule. RESULTS The highest risk factors associated with asthma hospitalization from the ED are oxygen saturation less than 94%, respiratory rate greater than 31/min, history of pneumonia, and asthma ED visits in past 12 months. With a reduced predictive model that combined these risk factors, the odds ratio was 44.9 (95% CI, 32.8-61.4), which is extremely significant. Our C index of discrimination of 0.77 was similar to the validation C index of 0.78, which confirms a solid prediction model. CONCLUSION We have developed and internally validated a pediatric hospitalization prediction index for acute asthma exacerbation in the ED. Further studies are needed to externally validate the APIH before its implementation into clinical practice.

Abstract
BACKGROUND Asthma attacks are common and have significant physical, psychological, and financial consequences. Improving the assessment of a child's risk of subsequent asthma attacks could support front-line clinicians' decisions on augmenting chronic treatment or specialist referral. We aimed to identify predictors for emergency department (ED) or hospital readmission for asthma from the published literature. METHODS We searched MEDLINE, EMBASE, AMED, PsycINFO, and CINAHL with no language, location, or time restrictions. We retrieved observational studies and randomized controlled trials (RCT) assessing factors (personal and family history, and biomarkers) associated with the risk of ED re-attendance or hospital readmission for acute childhood asthma. RESULTS Three RCTs and 33 observational studies were included, 31 from Anglophone countries and none from Asia or Africa. There was an unclear or high risk of bias in 14 of the studies, including 2 of the RCTs. Previous history of emergency or hospital admissions for asthma, younger age, African-American ethnicity, and low socioeconomic status increased risk of subsequent ED and hospital readmissions for acute asthma. Female sex and concomitant allergic diseases also predicted hospital readmission. CONCLUSION Despite the global importance of this issue, there are relatively few high quality studies or studies from outside North America. Factors other than symptoms are associated with the risk of emergency re-attendance for acute asthma among children. Further research is required to better quantify the risk of future attacks and to assess the role of commonly used biomarkers.

Abstract
INTRODUCTION This study assessed the relationship between secondhand smoke exposure (SHSe) as measured by serum cotinine and healthcare utilization among children. METHODS In 2016, the 2009-2012 National Health and Nutrition Examination Survey data were analyzed including 4,985 children aged 3-19 years. Associations between SHSe and having a routine place for healthcare, type of place, and hospital utilization were examined using logistic regression models. Poisson regression analyses assessed the relationship between SHSe and number of hospital admissions. Relationships between SHSe and acute care visits and hospital utilization were examined among asthmatic children. RESULTS SHSe level did not differ by having a routine place for healthcare, although children with high SHSe indicative of active smoking (cotinine ≥3 ng/mL) were 3.49 times (95% CI=1.77, 6.89) more likely to use an emergency department. Children with high SHSe were 2.85 times (95% CI=1.87, 4.34) more likely to have had an overnight hospital stay. Children with high SHSe had 2.05 times (95% CI=1.46, 2.87) the risk of having a higher number of hospital admissions for overnight stays versus children with no SHSe (cotinine <0.05 ng/mL). Among asthmatic children, those with high SHSe and low SHSe (cotinine 0.05-2.99 ng/mL) were more likely to have an acute care visit, overnight hospital stay, and higher number of hospital admissions than asthmatic children with no SHSe. CONCLUSIONS High SHSe is associated with increased healthcare utilization. The emergency department and inpatient settings are important venues in which to routinely offer cessation and SHSe reduction interventions.

Abstract
OBJECTIVE To examine the effect of final exam stress on the concentrations of leukotriene B4 (LTB4) and vascular endothelial growth factor (VEGF) in the upper airways among healthy and asthmatic individuals. METHOD Nasal samples were collected from 12 individuals with asthma and 23 healthy controls early and late in a final exam period, and during a low-stress period in the semester. We determined LTB4 and VEGF concentrations using Enzyme-Linked Immunoassays. RESULTS Mixed effects analysis of variance models showed that asthmatic participants with allergies in contrast to healthy individuals experienced a decrease in nasal LTB4 during the final exam period as compared to mid-semester (low stress period). There were no significant changes in nasal VEGF across the observation period. Changes in nasal LTB4 and VEGF were not associated with salivary cortisol, exhaled nitric oxide, or spirometric lung function. CONCLUSIONS Our results suggest that nasal LTB4 concentrations change in periods of psychological stress for asthmatic individuals with allergies.

Abstract
Severe asthma is recognised as an important and emerging area of unmet need in asthma. The assessment of severe asthma should include three steps; (1) determining the diagnosis of asthma, including verification that the disease is severe asthma, (2) assessing comorbidities and contributing factors that will impact on clinical severity, as well as (3) assessing asthma phenotypes. These steps recognize the importance of heterogeneity in asthma as a key factor that determines the disease course and increasingly the choice of successful therapy. This assessment should be undertaken systematically and is best done by an expert multidisciplinary team. Here, we will outline the important aspects that should be included in the clinical assessment of the patient in the severe asthma clinic, including diagnosis, clinical history, the assessment of important comorbidities and the key investigations needed to support them.

Abstract
The purpose of this study was to explore risk factors related to asthma prevalence among preschool and school-aged children using a representative national dataset from the Korea National Health and Nutrition Examination Survey (KNHANES) conducted from 2009–2011. We evaluated the demographic information, health status, household environment, socioeconomic status, and parents’ health status of 3,542 children aged 4–12 years. A sex-stratified multivariate logistic regression was used to obtain adjusted prevalence odds ratios (ORs) and 95% confidence intervals after accounting for primary sample units, stratification, and sample weights. The sex-specific asthma prevalence in the 4- to 12-year-old children was 7.39% in boys and 6.27% in girls. Boys and girls with comorbid atopic dermatitis were more likely to have asthma than those without atopic dermatitis (boys: OR = 2.20, p = 0.0071; girls: OR = 2.33, p = 0.0031). Boys and girls with ≥1 asthmatic parent were more likely to have asthma than those without asthmatic parents (boys: OR = 3.90, p = 0.0006; girls: OR = 3.65, p = 0.0138). As girls got older, the prevalence of asthma decreased (OR = 0.90, p = 0.0408). Girls residing in rural areas were 60% less likely to have asthma than those residing in urban areas (p = 0.0309). Boys with ≥5 family members were more likely to have asthma than those with ≤3 family members (OR = 2.45, p = 0.0323). The factors related to asthma prevalence may differ depending on sex in preschool and school-aged children. By understanding the characteristics of sex-based differences in asthma, individualized asthma management plans may be established clinically.
