Food allergy emergency preparedness in Illinois schools: rural disparity in guideline implementation

Food Allergy

Food allergy is a growing health problem affecting both pediatric and adult patients. Food allergies are often immunoglobulin E (IgE) mediated but other food-induced non-IgE-mediated diseases exist. Diagnosis of food allergy relies on the combination of clinical and reaction history, skin and IgE testing as well as oral food challenges. Although oral immunotherapy has been able to achieve sustained unresponsiveness in some patients, no cure for food allergies has been found to date. Avoidance of the inciting food as well as availability of epinephrine autoinjectors remains the mainstay of treatment.

Parental Health Literacy, Empowerment, and Advocacy for Food Allergy Safety in Schools: A Cross-Sectional Study

BACKGROUND

Approximately 8% of elementary school-aged children in the United States have food allergies, a complicated health management situation that requires parents to use many types of health literacy, empowerment, and advocacy skills to work with school staff to protect their children.

OBJECTIVE

This cross-sectional study examined (a) whether the highest versus lowest levels of functional, communicative, and critical health literacy are associated with higher perceived effectiveness of parental advocacy behaviors for safe food allergy management in schools [parental advocacy]; and (b) whether communicative and critical health literacy are more strongly associated with parental advocacy than functional health literacy.

METHODS

A sample of parents of elementary school-aged children was recruited through 26 food allergy organizations and a research patient registry. Participants completed an anonymous online survey. Self-reported measurements of parental health literacy, empowerment, and advocacy were adapted and refined through pre-testing and pilot-testing. General linear model analyses were conducted to predict parental advocacy.

KEY RESULTS

Participants (N = 313) were predominantly White, college-educated mothers with moderately high levels of food allergy knowledge, health literacy, empowerment, and parental advocacy skills. Parents who scored at the highest levels in the three dimensions of health literacy reported they engaged in more effective advocacy behaviors than parents who scored at the lowest levels. Parental advocacy was predicted largely by parental empowerment and the quality of the relationship with the school (B = .41 and B = .40, respectively). Functional health literacy and the child's diagnosis of asthma were smaller predictors. While accounting for covariates, functional health literacy was significantly associated with parental advocacy whereas communicative and critical health literacy were not.

CONCLUSIONS

Interventions to impact parental empowerment and parent-school relationships, including a health-literate universal precautions approach of communicating food allergy school policies, may influence parental advocacy for food allergy safety in schools. Further research could use a performance-based multidimensional measure of health literacy. [HLRP: Health Literacy Research and Practice. 2023;7(3):e165-e175.].

Disparities in the Diagnosis and Management of Anaphylaxis

PURPOSE OF REVIEW

The goal of this review is to characterize health disparities impacting the recognition and treatment of anaphylaxis.

RECENT FINDINGS

Previous research has identified major health disparities related to atopic conditions including asthma, atopic dermatitis, and food allergies (FA); however, disparities related to anaphylaxis have yet to be examined in depth. We found widespread health disparities in the incidence and severity of anaphylaxis, as well as in the management of allergies (particularly food allergies) that place individuals at risk of anaphylaxis. Sociodemographic factors are associated with numerous negative health outcomes related to anaphylaxis. We highlight several key steps that must be taken to address these disparities.

Social disparities in early childhood prevention and management of food allergy

Food allergy (FA) affects 8% of US children. Navigating and managing FA permeates across multiple facets of childhood. In this article, we review research on social disparities in feeding practices, managing meals, and selecting childcare and schools. Key highlights include the following: (1) although preference for breast-feeding or formula feeding does not reduce FA risk, there are disparities in access to formula that may affect children with FA; (2) disparities likely exist in the early introduction to allergenic foods, though additional research is needed to identify barriers to following the most recent consensus guidelines on early introduction; (3) families with limited income face challenges in providing safe meals for their children; (4) disparities exist in early childcare options for preschool-age children, though there is a lack of research on FA practices in these settings; and (5) there is evidence that schools with different student demographics implement different types of FA policies. Further research is needed to better understand and characterize social disparities in FA prevention and management in early childhood and to develop evidence-based strategies to reduce them.

Diagnosis and Management of Insect Allergy: Barriers and Facilitators in the United States

While guidelines recommend testing and treatment for patients with venom-induced anaphylaxis to prevent morbidity and mortality, significant barriers prevent most patients from receiving the evaluation and treatments that they need. This review examines these barriers in the United States along with the facilitators that can be used to overcome them.

Quality of Life in Food Allergy: Validation of the Korean Version of the Food Allergy Quality of Life Questionnaire Parent Form (K-FAQLQ-PF) and Risk Factor Analysis

PURPOSE

This study aimed to evaluate the reliability and validity of the Korean version of the Food Allergy Quality of Life Questionnaire-Parent Form (K-FAQLQ-PF) and to identify clinical characteristics related to low quality of life (QoL) in Korean children with food allergy (FA).

METHODS

Parents of 0-12-year-old patients with FA were enrolled. The English version of FAQLQ-PF was translated into Korean. Construct validation was confirmed by the Food Allergy Independent Measure-Parent Form (FAIM-PF) and the Child Health Questionnaire Parent Form 28 (CHQ-PF28). Logistic regression analyses were used to evaluate associations between potential risk factors and QoL outcomes.

RESULTS

A total of 182 patients with a median age of 5.0 years were enrolled in the study. Cronbach's α coefficient values indicating internal consistency were higher than 0.8. Intraclass correlation coefficient values for test-retest reliability were good for all age groups (r > 0.6). Total K-FAQLQ-PF scores were positively correlated with the FAIM-PF (r = 0.56, P < 0.05) and were negatively correlated with the parental impact-emotional domain in the CHQ-PF28 (r = -0.44, P < 0.05). In multivariable logistic regression analysis, low QoL was significantly associated with female sex (adjusted odds ratio [aOR], 2.07; 95% confidence interval [CI], 1.03-4.18), age ≥ 5 years (aOR, 2.84; 95% CI, 1.31-6.16), FA diagnosis before the age of 3 years (aOR, 3.96; 95% CI, 1.13-13.93), the presence of atopic dermatitis (aOR, 2.21; 95% CI, 1.07-4.57), and residence in non-metropolitan areas (aOR, 3.44; 95% CI, 1.73-6.85).

CONCLUSIONS

According to parental perceptions, the K-FAQLQ-PF is a valid and reliable tool to assess psychosocial QoL in Korean children with FAs. Age, sex, residential area, and comorbid AD can affect the QoL of pediatric patients with FA.

Telehealth and Allergy Services in Rural and Regional Locations That Lack Specialty Services

Secondary to the coronavirus disease 2019 pandemic, telehealth quickly peaked as the dominant health care modality and its use still remains high. Although allergists and health care systems adapted quickly to adopt telehealth, its increased use has both highlighted its benefits for patients and allergists and demonstrated known concerns with delivering allergy specialty care to rural and regional patient populations. With increased concentration of both patients and allergists in urban areas, the ability to provide allergy specialty care to the rural and remote population continues to remain a challenge despite the advantages leveraged through telehealth. Herein, we review aspects specific to the rural patient population, tele-allergy outcomes with these patient cohorts, and efforts, both past and present, taken at different levels within the allergy community to promote our specialty through specific telehealth modalities to address and engage the rural and regional patient.

Health disparities in pediatric food allergy

OBJECTIVE

To review the current literature regarding the health disparities in the prevalence, diagnosis, and management of pediatric food allergy and discuss possible interventions.

DATA SOURCES

Literature search of PubMed and Google Scholar databases regarding pediatric food allergy and health disparities.

STUDY SELECTIONS

Original research articles, reviews, and guidelines on health disparities in pediatric food allergy were included in this review.

RESULTS

The overall prevalence of food allergy appears to be increasing and disproportionately affecting minority groups. Racial and socioeconomic disparities are evident across all aspects of food allergy care: diagnosis, prevention, acute management (eg, access to epinephrine autoinjectors, visits to emergency department), and long-term management (eg, oral immunotherapy). Children of minority populations and those of low socioeconomic status are at a greater risk of food insecurity, which is further exacerbated by the high cost of allergen-free foods and limited support from food assistance programs.

CONCLUSION

Racial, ethnic, and socioeconomic disparities in food allergy among children in the United States are evident and negatively affect the outcomes of children with food allergies. Active efforts to decrease racial and socioeconomic disparities, through education, research, and advocacy, will be important to help improve health outcomes in food allergy for all children, regardless of their race, ethnicity, or socioeconomic status.

Recognition and Management of Food Allergy and Anaphylaxis in the School and Community Setting

Given the increasing prevalence of food allergy, schools and food service establishments must have procedures in place to accommodate those with the condition. Training staff on allergy management has been shown to improve knowledge and skills, although more research is needed to better understand its benefits. Furthermore, although there are challenges involved in maintaining unassigned stock epinephrine programs, they have the potential to reduce morbidity and mortality associated with anaphylaxis by improving access to potentially life-saving medication. Finally, food bans in schools may not be an effective part of food allergy management, and other measures should be considered instead.

School allergy training promotes internal policy review and enhances staff's preparedness in managing pupils with food allergy

Background

Recently non‐statutory allergy management guidance for schools has been produced in the United Kingdom; however, there has been limited progress in implementing this. The aim of this study was to evaluate the effect of face‐to‐face training on self‐reported school staff preparedness in managing the severely allergic child and whether it would stimulate schools' allergy policy review.

Methods

A preparedness survey was conducted prior and 2 months post‐intervention to assess the effect of training on self‐reported preparedness and perceived confidence to manage children with food allergies.

Results

A sample of 18 primary schools that consented to participate were selected. Of the trained schools, 89% of the head teachers felt confident in dealing with an allergy emergency compared to 39% prior training (p = 0.016). Post‐intervention all but one had arranged/were considering introducing allergy awareness sessions to help pupils manage their allergies (45% pre‐training vs. post‐training 93%, p = 0.003). Preventative measures for accidental exposure to food allergens (i.e., no food sharing policy) were adopted by all (pre‐training 61% vs. post‐training 100%, p = 0.03).

Conclusion

A face‐to‐face school allergy training programme enhances self‐reported staff preparedness and promotes internal allergy policy review in managing the needs of these children, hence addressing the current gap between recommendations and practice in schools.

Prevention and management of allergic reactions to food in child care centers and schools: Practice guidelines

Food allergy management in child care centers and schools is a controversial topic, for which evidence-based guidance is needed. Following the Grading of Recommendations Assessment, Development, and Evaluation approach, we conducted systematic literature reviews of the anticipated health effects of selected interventions for managing food allergy in child care centers and schools; we compiled data about the costs, feasibility, acceptability, and effects on health equity of the selected interventions; and we developed the following conditional recommendations: we suggest that child care centers and schools implement allergy training and action plans; we suggest that they use epinephrine (adrenaline) to treat suspected anaphylaxis; we suggest that they stock unassigned epinephrine autoinjectors, instead of requiring students to supply their own personal autoinjectors to be stored on site for designated at-school use; and we suggest that they do not implement site-wide food prohibitions (eg, "nut-free" schools) or allergen-restricted zones (eg, "milk-free" tables), except in the special circumstances identified in this document. The recommendations are labeled "conditional" due to the low quality of available evidence. More research is needed to determine with greater certainty which interventions are likely to be the most beneficial. Policymakers might need to adapt the recommendations to fit local circumstances.

Health disparities in allergic and immunologic conditions in racial and ethnic underserved populations: A Work Group Report of the AAAAI Committee on the Underserved

Health disparities are health differences linked with economic, social, and environmental disadvantage. They adversely affect groups that have systematically experienced greater social or economic obstacles to health. Renewed efforts are needed to reduced health disparities in the United States, highlighted by the disparate impact on racial minorities during the coronavirus pandemic. Institutional or systemic patterns of racism are promoted and legitimated through accepted societal standards, and organizational processes within the field of medicine, and contribute to health disparities. Herein, we review current evidence regarding health disparities in allergic rhinitis, asthma, atopic dermatitis, food allergy, drug allergy, and primary immune deficiency disease in racial and ethnic underserved populations. Best practices to address these disparities involve addressing social determinants of health and adopting policies to improve access to specialty care and treatment for the underserved through telemedicine and community partnerships, cross-cultural provider training to reduce implicit bias, inclusion of underserved patients in research, implementation of culturally competent patient education, and recruitment and training of health care providers from underserved communities. Addressing health disparities requires a multilevel approach involving patients, health providers, local agencies, professional societies, and national governmental agencies.

Community Use of Epinephrine for the Treatment of Anaphylaxis: A Review and Meta-Analysis

BACKGROUND

Community use of epinephrine for the treatment of anaphylaxis is low. Knowledge of rates of epinephrine use in the pre-hospital setting along with identification of barriers to its use will contribute to the development of policies and guidelines.

OBJECTIVES

A search was conducted on PubMed and Embase in April 2020. Our systematic review focused on 4 domains: (1) epinephrine use in the pre-hospital setting; (2) barriers to epinephrine use in the pre-hospital setting; (3) cost evaluation and cost-effectiveness of epinephrine use; and (4) programs and strategies to improve epinephrine use during anaphylaxis.

METHODS

Two meta-analyses with logit transformation were conducted to: (1) calculate the pooled estimate of the rate of epinephrine use in the pre-hospital setting among cases of anaphylaxis and (2) calculate the pooled estimate of the rate of biphasic reactions among all cases of anaphylaxis.

RESULTS

Epinephrine use in the pre-hospital setting was significantly higher for children compared with adults (20.98% [95% confidence interval (CI): 16.38%, 26.46%] vs 7.17% [95% CI: 2.71%, 17.63%], respectively, P = .0027). The pooled estimate of biphasic reactions among all anaphylaxis cases was 3.92% (95% CI: 2.88%, 5.32%). Our main findings indicate that pre-hospital use of epinephrine in anaphylaxis remains suboptimal. Major barriers to the use of epinephrine were identified as low prescription rates of epinephrine autoinjectors and lack of stock epinephrine in schools, which was determined to be cost-effective. Finally, in reviewing programs and strategies, numerous studies have engineered effective methods to promote adequate and timely use of epinephrine.

CONCLUSION

The main findings of our study demonstrated that across the globe, prompt epinephrine use in cases of anaphylaxis remains suboptimal. For practical recommendations, we would suggest considering stock epinephrine in schools and food courts to increase the use of epinephrine in the community. We recommend use of pamphlets in public areas (ie, malls, food courts, etc.) to assist in recognizing anaphylaxis and after that with prompt epinephrine administration, to avoid the rare risk of fatality in anaphylaxis cases.

Impact of a Comprehensive Guideline Dissemination Strategy on Diabetes Diagnostic Test Rates: an Interrupted Time Series

BACKGROUND

Diabetes Canada launched a comprehensive Dissemination and Implementation (D&I) strategy to optimize uptake of their 2013 Clinical Practice Guidelines; the strategy involved continuing professional development courses, webinars, an interactive website, applications for mobile devices, point-of-care decision support tools, and media awareness campaigns. It included a focus on promoting HbA1c as the recommended diagnostic test for diabetes.

OBJECTIVE

To determine the impact of Diabetes Canada's 2013 D&I strategy on physician test-ordering behavior, specifically HbA1c testing, for the diagnosis of diabetes, using provincial healthcare administrative data.

DESIGN

Population-based interrupted time series.

SETTING

Ontario, Canada.

PARTICIPANTS

Ontario residents aged 40-79 not previously diagnosed with diabetes.

MEASUREMENTS

For each quarter between January 2005 and December 2014, we conducted an interrupted time series analysis on the first-order difference of the proportion of patients receiving HbA1c tests per quarter with an autoregressive integrated moving average model with the intervention step occurring in quarter 2 of 2013. Subgroup analyses by rurality, physician graduation year, and practice size were also conducted.

RESULTS

There were 32 quarters pre-intervention and 6 post-intervention; average sample size per quarter was 5,298,686 individuals. Pre-intervention, the quarter-to-quarter growth was 1.51 HbA1c tests per quarter per 1000 people. Post-intervention, the quarter-to-quarter growth increased by 8.45 tests per 1000 people (p < 0.005). Growth of HbA1c ordering differed significantly by region, years since physician graduation, and practice size.

LIMITATIONS

Incomplete data collection, inadequate stratification, and other unidentified confounders.

CONCLUSION

The D&I strategy resulted in a significant increase in the growth of HbA1c tests. The successful uptake of this recommendation may be due to its simplicity; guideline developers should consider this when drafting recommendations. Furthermore, differential uptake by user groups suggests that future strategies should include targeted barrier analysis and interventions to these groups.

Food Allergy Management at School in the Era of Immunotherapy

PURPOSE OF REVIEW

Food allergy is increasing in prevalence, and management focuses on strict avoidance of known allergens and appropriately treating reactions. Any reaction has the potential to result in anaphylaxis, which can be fatal. Children spend a significant amount of time in the childcare or school setting, and interactions between families, school personnel, and clinicians are important to ensure the health and safety of children with allergies and asthma.

RECENT FINDINGS

This review examines current food allergy guidelines and legislation, an assessment of allergen-free schools, the importance of written anaphylaxis action plans, training and education of school personnel, emerging treatment options, and the social implications of having food allergies. As the clinical use and research into food allergen immunotherapy continues to expand, an additional level of education and management is required of school personnel and caregivers. Food allergy has both medical and social implications, which are magnified in the school setting.

How to manage food allergy in nursery or school

PURPOSE OF REVIEW

The aim of this review is to describe effective management strategies in nursery or school based upon research findings.

RECENT FINDINGS

The prevalence of food allergy and number of emergency department visits for food-related anaphylaxis are increasing in children and adolescents. As there is currently no cure, the most effective strategy to decrease allergic reactions is food allergen avoidance. However, allergic reactions are inevitable in both food allergic children as well as in first-time reactors. Misconceptions exist on the safety of products with advisory labels and questions remain on whether school-wide bans decrease the risk of allergic reactions in school. Recent legislation has prompted schools to consider requiring unassigned epinephrine autoinjectors to better manage those who have allergic reactions in nursery or school.

SUMMARY

A collective effort is required to keep children with food allergies safe at school. Families, healthcare providers, and school personnel should be informed on food allergen avoidance strategies, symptoms consistent with allergic reactions and anaphylaxis, how to respond to allergic reactions, and the impact the diagnosis of food allergy may have on quality of life for affected children and their families.

Barriers to the Administration of Epinephrine in Schools

BACKGROUND

Anaphylaxis is a serious and growing concern in the school setting as the prevalence of food allergies and food-induced severe allergic reactions continues to increase.

METHODS

A cross-sectional, web-based survey was conducted regarding anaphylactic events that occurred during the 2014-2015 school year. Eligible schools were enrolled in the EPIPEN4SCHOOLS^® program (Mylan Specialty L.P., Canonsburg, PA), which provides free epinephrine auto-injectors to qualifying US schools. Participating schools completed a 29-item survey on anaphylactic event occurrence and treatment, epinephrine stock, school policies regarding anaphylaxis, school staff training, and school nursing coverage.

RESULTS

Responses were provided by 12,275 schools. Epinephrine was administered on school property for 63.7% of reported anaphylactic events (1272/1998). In 38.5% (235/610) of events for which epinephrine was not used, antihistamines were cited as the reason. Only 59.4% of schools cited epinephrine as their standard first-line therapy for anaphylaxis. School nurses were most likely to be trained in anaphylaxis recognition and permitted to administer epinephrine; however, just 53.6% of schools had a full-time nurse on staff.

CONCLUSIONS

Process-related barriers to the appropriate use of epinephrine go beyond access to medication. Widespread staff training and review of school policies are needed to ensure that anaphylaxis is appropriately managed in schools.

The Allergist's Role in Anaphylaxis and Food Allergy Management in the School and Childcare Setting

Anaphylaxis and food allergy management in childcare facilities and schools are growing challenges. An increasing number of children experience severe allergic reactions on school grounds as evidenced by reports of epinephrine use. Data also suggest that the prevalence of food allergy may be increasing, with a large percentage of school-aged children at risk for anaphylaxis. Moreover, anaphylaxis may occur for the first time in a previously undiagnosed child at school or childcare setting, suggesting that general preparedness is essential. Management includes strategies for minimizing the risk of reactions and allergen exposures as well as readiness to recognize and treat allergic reactions of any severity. The primary objective of this report is to offer health care providers an overview of relevant evidence, resources, and expert opinion to assist with developing interprofessional collaborative counsel on school food allergy management and anaphylaxis preparedness with families, schools, and childcare settings. We present the current evidence base, suggest resources, and highlight areas of current controversy that warrant further study.

Exploring School Nurse Interventions and Health and Education Outcomes: An Integrative Review

School nurses intervene with students, parents, and school staff to advance the health and academic success of students. We conducted an integrative literature review of published research to describe the types of school nurse interventions and health and education outcome measures and to examine how school nurse interventions were linked to student outcomes. Sixty-five studies met the inclusion criteria. We used the National Association of School Nurses' Framework for 21st Century School Nursing Practice to categorize school nurse interventions and health and education outcome measures. The majority of interventions were categorized under the care coordination principle, most commonly, motivational interviewing and counseling. In 17 studies, school nurse interventions were linked to improved student outcomes. Most studies (80%) were descriptive. To advance school nursing science, researchers can build on this foundation with more rigorous research methods to evaluate the impact of school nurse interventions and activities on student health and education outcomes.

Food allergy: A review and update on epidemiology, pathogenesis, diagnosis, prevention, and management

This review provides general information to serve as a primer for those embarking on understanding food allergy and also details advances and updates in epidemiology, pathogenesis, diagnosis, and treatment that have occurred over the 4 years since our last comprehensive review. Although firm prevalence data are lacking, there is a strong impression that food allergy has increased, and rates as high as approximately 10% have been documented. Genetic, epigenetic, and environmental risk factors are being elucidated increasingly, creating potential for improved prevention and treatment strategies targeted to those at risk. Insights on pathophysiology reveal a complex interplay of the epithelial barrier, mucosal and systemic immune response, route of exposure, and microbiome among other influences resulting in allergy or tolerance. The diagnosis of food allergy is largely reliant on medical history, tests for sensitization, and oral food challenges, but emerging use of component-resolved diagnostics is improving diagnostic accuracy. Additional novel diagnostics, such as basophil activation tests, determination of epitope binding, DNA methylation signatures, and bioinformatics approaches, will further change the landscape. A number of prevention strategies are under investigation, but early introduction of peanut has been advised as a public health measure based on existing data. Management remains largely based on allergen avoidance, but a panoply of promising treatment strategies are in phase 2 and 3 studies, providing immense hope that better treatment will be imminently and widely available, whereas numerous additional promising treatments are in the preclinical and clinical pipeline.
