Effectiveness of the Spirometry 360 Quality Improvement Program for Improving Asthma Care: A Cluster Randomized Trial

Defining and Promoting Pediatric Pulmonary Health: Assessing Lung Function and Structure

Lifelong respiratory health is rooted in the structural and functional development of the respiratory system in early life. Exposures and interventions antenatally through childhood can influence lung development into young adulthood, the life stage with the highest achievable lung function. Because early respiratory health sets the stage for adult lung function trajectories and risk of developing chronic obstructive pulmonary disease, understanding how to promote lung health in children will have far reaching personal and population benefits. To achieve this, it is critical to have accurate and precise measures of structural and functional lung development that track throughout life stages. From this foundation, evaluation of environmental, genetic, metabolic, and immune mechanisms involved in healthy lung development can be investigated. These goals require the involvement of general pediatricians, pediatric subspecialists, patients, and researchers to design and implement studies that are broadly generalizable and applicable to otherwise healthy and chronic disease populations. This National Institutes of Health workshop report details the key gaps and opportunities regarding lung function and structure.

Statewide Asthma Learning Collaborative Participation and Asthma-Related Emergency Department Use

BACKGROUND

Quality improvement (QI) efforts can improve guideline-recommended asthma care processes in the pediatric office setting. We sought to assess whether practice participation in an asthma QI collaborative was associated with decreased asthma-related emergency department (ED) visits.

METHODS

A statewide network of practices participated in a pediatric asthma QI collaborative from 2015 to 2016. We evaluated asthma-related ED visit rates per 100 child-years for children ages 3 to 21 years with asthma, using the state's all-payer claims database. We used a difference-in-differences approach, with mixed-effects negative binomial regression models to control for practice and patient covariates. Our main analysis measured the outcome before (2014) and after (2017) the QI collaborative at fully participating and control practices. Additional analyses assessed (1) associations during the intervention period (2016) and (2) associations including practices partially participating in QI collaborative activities.

RESULTS

In the postintervention year (2017), participating practices' (n = 20) asthma-related ED visit rate decreased by 5.8 per 100 child-years, compared to an increase of 1.8 per 100 child-years for control practices (n = 15; difference in differences = -7.3; P = .002). Within the intervention year (2016), we found no statistically significant differences in asthma-related ED visit rates compared to controls (difference in differences = -4.3; P = .17). The analysis including partially participating practices yielded similar results and inferences to our main analysis.

CONCLUSIONS

Participation in an asthma-focused QI collaborative was associated with decreased asthma-related ED visit rates. For those considering implementing this type of QI collaborative, our findings indicate that it takes time to see measurable improvements in ED visit rates. Further study is warranted regarding QI elements contributing to success for partial participants.

Controversies in Pediatric Asthma

Pediatric asthma, the most common chronic disease of childhood, remains a significant burden to the health care system. Although there are guidelines for the management of pediatric asthma, there remain several controversies about how best to manage asthma in the primary care setting, and how to prevent asthma exacerbations and subsequent emergency department visits and hospitalizations. In this article, we address four of these controversies: use of written asthma treatment plans, the role of long-acting beta-agonists, spirometry and peak flow measurements in disease management, and engagement of school nurses in the health care team. We provide suggestions and guidance related to these topics for the pediatric primary care provider. [Pediatr Ann. 2019;48(3):e128-e134.].
