Statewide asthma learning collaborative participation and asthma-related emergency department use.
This study looked at outcomes from participation of pediatric practices in a quality improvement (QI) collaborative to decrease asthma-related emergency department (ED) visits. A statewide network of practices participated in the collaborative from 2015 to 2016. Asthma-related ED visit rates per 100 child-years for children ages 3 to 21 was evaluated using the state’s all-payer claims databases. The authors found that in the postintervention year (2017) participating practices’ ED visit rate decreased by 5.8 per 100 child-years, compared to an increase of 1.8 per 100 child-years in non-participating practices. There were no statistically significant differences in asthma-related ED visit rates during 2016, which indicated that it took some time for QI elements to be successfully implemented in pediatric practices.

Steroid variability in pediatric inpatient asthmatics: survey on provider preferences of dexamethasone versus prednisone.
This study looked at pediatric emergency department (ED) inpatient use of dexamethasone versus prednisone by providers for asthma treatment. A survey was distributed to providers who care for inpatient asthmatics. Ninety-two providers completed the survey. When patients received dexamethasone in the ED, 44% continued dexamethasone, 14% switched to prednisone, 2% stopped steroid use, and 40% said it depended on the circumstances. Hospitalists were significantly more likely to continue dexamethasone than pulmonologists (61% versus 15%). Switching to prednisone included factors such as severity of exacerbation (73%) and asthma history (47%). Just over half of providers (5f1%) felt uncomfortable using dexamethasone because of “minimal data to support [its] use inpatient.”

Keeping risk in context while rethinking the setting of asthma biologics in patient-centered care.
This perspective article discusses the benefits and risks of patients with severe asthma self-administering asthma biologics at home instead of at a physician’s office. While most biologics are now FDA-approved to be administered at home, many of them are also recommended by the FDA to be administered by a health care professional with post-injection monitoring due to the possibility of post-injection anaphylaxis. The authors argue that there can be more risk associated with getting into an automobile accident on the way to or from the clinic or office. Given the current circumstances with limited patient visit hours due to COVID-19 it is even more important that patients can administer the biologic themselves.

Pathways to improve pediatric asthma care: a multisite, national study of emergency department asthma pathway implementation.
This quality improvement study’s aim was to determine the effects of pediatric asthma pathway implementation in a diverse, national sample of emergency departments (EDs). Desired outcomes included systemic corticosteroid administration within 60 minutes (primary), assessment of severity at ED triage, chest radiograph use, hospital admission or transfer for higher level of care, and ED length of stay. Charts were reviewed each month by EDs for children ages 2-17 years with a primary diagnosis of asthma. A total of 83 EDs were enrolled, with 37 of them children’s hospitals, and 46 community hospitals. Seventy-three percent completed the study (n = 22,963). There was a significant increase in systematic corticosteroid administration within 60 minutes of arrival as well as increased odds of severity assessment at triage and decreased rate of change in odds of hospital admission/transfer. Chest radiograph or ED length of stay was not associated with pathway implementation.

Best practices in implementing inpatient pediatric asthma pathways: a qualitative study.
The objective of this study was to identify potential best practices in pathway implementation. Building upon a previous observational study in which the researchers identified higher and lower performing children's hospitals based on hospital-level changes in asthma patient length of stay after implementation of a pathway, they conducted semi-structured interviews with a sample of healthcare providers involved in pathway implementation at these hospitals. They identified several potential best practices to support pathway implementation. They recommended that hospitals implementing pathways consider applying these strategies to ensure success in improving quality of asthma care for children.

Pathways for improving inpatient pediatric asthma care (PIPA): a multicenter, national study.
This study examined whether implementation of a pathway strategy for inpatient pediatric asthma patients improve outcomes for these patients. Outcomes measured included length of stay (LOS), early administration of metered-dose inhalers, screening for secondhand tobacco exposure and referral to cessation resources, and 7-day hospital readmissions or emergency revisits. Eighty-five hospitals were enrolled and 68 completed the study with (n=12,013) admissions. Pathways were associated with increases in early administration of metered-dose inhalers, and referral to smoking cessation resources, but no statistically significant changes in the other outcomes were observed. Most hospitals did improve in at least one outcome.

Intravenous magnesium in asthma pharmacotherapy: variability in use in the PECARN Registry.
Researchers examined the use, efficacy, and safety of intravenous magnesium sulfate (IVMg) in children with asthma whose emergency department (ED) management is recorded in the Pediatric Emergency Care Applied Research Network (PECARN) Registry. They found that, in PECARN Registry EDs, administration of IVMg occurred late in ED treatment, for a minority of the children likely to benefit, with variation between sites, which suggested the current clinical role for IVMg in preventing hospitalization was limited. Discharge after IVMg administration would likely be safe. They recommended further research to assess the efficacy and safety of early IVMg administration.

Dose, timing, and type of infant antibiotic use and the risk of childhood asthma.
This study examined the association between dose, timing and type of infant antibiotic use and the risk of childhood asthma. The study examined a cohort of 152,622 children enrolled in the Tennessee Medicaid Program. At least 79% had at least one antibiotic prescription fill during infancy. There was a 20% increase in odds of childhood asthma for each additional antibiotic filled. There was no significant association between timing, formulation, anaerobic coverage and class of antibiotics and childhood asthma. However, broad spectrum antibiotic fills increased the odds of development of childhood asthma compared to narrow spectrum only fills.

Trends in regionalization of emergency care for common pediatric conditions.
This study examined trends in regionalization of emergency care for common pediatric conditions. The authors sought to determine how the likelihood of definitive care has changed for 3 common conditions: asthma, croup, and gastroenteritis. They used the National Emergency Department Sample Database to study children from 2008 to 2016 who presented to emergency departments with those primary diagnoses, excluding critically ill patients. Researchers conducted analyses by stratification of annual emergency department pediatric volume categorized by quartiles. Referral rates increased for all conditions in all volume quartiles, with referral rates greatest in the lowest pediatric volume quartile.

Association of obstructive sleep apnea with severity of patients hospitalized for acute asthma. Ann Allergy Asthma Immunol 2020 Feb;124(2):165-70.e4. doi: 10.1016/j.anai.2019.11.002.
Researchers investigated the association of obstructive sleep apnea (OSA) with acute asthma severity in a retrospective cohort study that used State Inpatient Databases from eight geographically diverse states. Outcomes examined were markers of acute severity such as mechanical ventilation use, hospital length of stay, and in-hospital mortality. The researchers found that, among patients hospitalized for acute asthma, OSA was associated with a higher risk of noninvasive positive pressure ventilation use and longer length of stay compared with those without OSA.

Estimation of health and economic benefits of clinic versus home administration of omalizumab and mepolizumab.
Biologic therapy is a paradigm-shifting management strategy for many patients with asthma and chronic urticaria, but concerns for therapy-associated anaphylaxis may limit access to these therapies for patients unable to travel to medical clinics. The objective of this study was to characterize the cost-effectiveness of in-clinic versus at-home biologic therapy with omalizumab and mepolizumab.

Managing asthma in low-income, underrepresented minority, and other disadvantaged pediatric populations: closing the gap.
The authors review current understanding of the epidemiology and etiology of disparities in asthma. They also highlight current and emerging literature on solutions to tackle disparities while underscoring gaps and pressing future directions. Tailored, multicomponent approaches including the home, school, and clinician-based interventions show great promise. Managing asthma in disadvantaged populations can be challenging as they tend to have disproportionately worse outcomes due to a multitude of factors.

Asthma Control Test.
In this study, the investigators compared results of a modified version of the Asthma Control Test using parent proxy report (PP-ACT) with results reported by children and parents using the validated Childhood-Asthma Control Test (C-ACT). ). The investigators indicate that that while the PP-ACT missed few children with uncontrolled asthma and may simplify reporting of asthma control in circumstances when child report is not feasible or creates barriers to survey receipt, limitations of proxy reporting should be considered.

Geographic and racial variation in asthma prevalence and emergency department use among Medicaid-enrolled children in 14 southern states.
Using 2007 Medicaid claims data from 556 counties in 14 southern states, the researchers described the local area variation in 1-year asthma prevalence rates, emergency department visit rates, and racial disparity rate ratios. They found much local area variation in asthma prevalence and asthma ED visit rates among Medicaid-enrolled children. Between black and white children, more counties had higher prevalence of asthma and higher ED visit rates among blacks.

Obesity and asthma: pathophysiology and implications for diagnosis and management in primary care.
This review summarizes existing data that support the pathophysiologic mechanisms underlying the association between obesity and asthma, as well as the current and future state of treatment for the obese patient with asthma. It suggests that evidence of chronic inflammatory response linking obesity and asthma indicates a need to address obesity during asthma management, possibly by using patient-centered approaches such as shared decisionmaking.

Use of leukotriene receptor antagonists are associated with a similar risk of asthma exacerbations as inhaled corticosteroids.
The researchers compared the effectiveness of different controller medication regimens under real-life conditions. They found that the risk of emergency department visits, hospitalizations, and oral corticosteroids did not differ between children who initiated leukotriene antagonist and those who initiated inhaled corticosteroid. These findings may be explainable by leukotriene antagonist having similar effectiveness as inhaled corticosteroid in real-life usage.

The impact of obesity on medication use and expenditures among nonelderly adults with asthma.
The author examined the impact of obesity on medication use and expenditures among nonelderly adults with asthma using the Medical Expenditure Panel Survey. He found that obese classes II/III individuals were more likely to have current asthma, seek treatment for asthma, use more medications, and have higher medication and health care expenditures compared with normal weight individuals. His results suggested that reduction in body weight may help reduce health resource use and expenditures for nonelderly adults with asthma.
