The Role of Home Environments in Allergic Disease

Establishing a Virtual Home Assessment Program: from Concept to Implementation as a Result of the COVID-19 Pandemic

PURPOSE OF REVIEW

Environmental home assessments have traditionally been performed in-person at the homes of Children's Mercy Kansas City patients. The COVID-19 pandemic brought many challenges to the way patients interact with their healthcare providers, including home visiting programs. Reaching out to patients with high-risk asthma and immunocompromised health was still needed, despite the pandemic. This project's purpose was to develop a virtual (telemedicine) healthy home assessment protocol that would continue to meet patients' needs during the isolation resulting from the pandemic.

RECENT FINDINGS

This is a newly developing approach to performing home environmental assessments with limited published research. Research on the effective use of telemedicine as an alternative to in-person clinic visits has shown that for some health conditions telemedicine represents a useful technique to engage with patients and caregivers. For some conditions, like pediatric asthma, it provides a similar level of efficacy in disease management while providing a more efficient form of interaction. This article describes the development and delivery process, timelines of caregiver interaction, and guidelines for performing virtual home assessments. It summarizes the challenges and benefits of using a virtual process for delivering home assessment services for asthma and allergy patients. Overall, caregivers indicated they found the use of virtual technology had significant benefits for them including their personal comfort and the time efficiency gained by using virtual visits to interact with Healthy Homes Program staff.

The Use and Teaching of Telemedicine in Allergy/Immunology Training Programs

PURPOSE OF REVIEW

The use of telemedicine has greatly increased since the onset of the coronavirus disease 2019 (COVID-19) pandemic. This review discusses the types of telemedicine, current telehealth curricula in medical education, and benefits and disadvantages of incorporation of telemedicine into Allergy/Immunology training programs.

RECENT FINDINGS

The majority of Allergists/Immunologists use telemedicine in their clinical practice with leaders in graduate medical education recommending inclusion of telemedicine in training. Fellows-in-training reported that use of telemedicine in Allergy/Immunology training during the pandemic mitigated some concerns for lack of adequate clinical experience. Still, no standardized curriculum for telemedicine training in Allergy/Immunology exists, although curricula from internal medicine and primary care residencies can provide a framework for incorporation of telemedicine training into fellowship. Benefits of telemedicine in Allergy/Immunology training include enhanced immunology training, home environment monitoring, and flexibility to reduce physician burnout while disadvantages include limited physical examination skill building and lack of a standardized curriculum. As telemedicine has been widely accepted in medicine with high patient satisfaction, it is necessary to incorporate a standardized telehealth curriculum in Allergy/Immunology fellowship training, both as a tool for patient care as well as trainee education.

Potential determinants of T helper 2 markers and their distribution in school-aged children

BACKGROUND

There is growing data on T helper 2 (Th2) biomarker determinants in adult populations. However, the determinants and typical range of these biomarkers have not been well studied in general populations of children. Therefore, we assessed the determinants and typical range of three Th2 biomarkers, including blood eosinophils, FeNO, and serum total IgE in 9-11-year-old children in a prospective birth cohort.

METHODS

We examined the pre- and postnatal factors associated with Th2 biomarkers using multivariable logistic regression analysis (n = 428) and extended the results to the original cohort (n = 17,009) using inverse probability weighting. We also measured typical Th2 biomarker distribution in all examined children and healthy participants without allergic diseases (n = 180).

RESULTS

At age 9-11, wheeze (odds ratio (OR) 7.63), rhinitis (OR 3.14), and eczema (OR 2.46) were significantly associated with increased blood eosinophils. All three allergic conditions were associated with FeNO and total serum IgE, but the ORs were smaller than those for blood eosinophils. Secondhand smoking was inversely associated with the blood eosinophils (OR, 0.38). Similar results were found in the original cohort. Male sex and prenatal factors (maternal smoking and parental history of allergies) were not independent predictors of high Th2 levels.

CONCLUSIONS

In addition to wheezing and rhinitis, eczema and secondhand smoke exposure are independent factors for Th2 biomarker interpretation in children. Furthermore, the typical values and cutoff values of blood eosinophils in adults may not be applicable to children.
