[PMID: 38923779 DOI: 10.1111/cea.14528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 06/12/2024] [Accepted: 06/13/2024] [Indexed: 06/28/2024]
Abstract
BACKGROUND There has been limited data regarding the incidence of anaphylaxis in Asia. We aim to describe patterns in patient characteristics, triggers and clinical presentation of childhood anaphylaxis in Singapore. METHODS This was a retrospective review of emergency electronic medical records of children with anaphylaxis. Patients with the allergy-related diagnoses of anaphylaxis, angioedema, allergy and urticaria based on ICD-9 codes were screened. Cases fulfilling the World Allergy Organization criteria for anaphylaxis were included. RESULTS A total of 1188 cases of anaphylaxis were identified with a median age of 6.3 years. Extrapolating data from the study sites, from 2015 to 2022, the incidence rate of childhood anaphylaxis emergency visits in Singapore doubled from 18.9 to 38.8 per 100,000 person-years, with an incidence rate ratio (IRR) of 2.06 (95% confidence interval [CI] 1.70-2.49). In 2022, the incidence rate of food anaphylaxis was 30.1 per 100,000 person-years, IRR 2.39 (95% CI 1.90-3.01) and drug anaphylaxis was 4.6 per 100,000 person-years, IRR 1.89 (95% CI 1.11-3.25). The incidence rate in children aged 0-4 years quadrupled during the study period. Common triggers were egg (10.4%), peanut (9.3%), tree nut (8.8%), milk (8%), shellfish (7.8%) and non-steroidal anti-inflammatory drug (4.4%). The majority (88.6%) of patients were treated with intramuscular adrenaline. Total number of allergy-related visits did not increase over time between 2015 and 2019. Rates of severe anaphylaxis, namely anaphylactic shock and admission to high-dependency and intensive care, did not increase over time, with a mean incidence of 1.6, IRR 0.85 (95% CI 0.40-1.83) and 0.7, IRR 1.77 (95% CI 0.54-5.76) per 100,000 person-years, respectively. CONCLUSION While the number of emergency visits due to childhood anaphylaxis has increased, the number of cases of allergy-related visits, anaphylactic shock and anaphylaxis requiring high-dependency and intensive care did not rise.

PREHOSP EMERG CARE 2024:1-8. [PMID: 38913542 DOI: 10.1080/10903127.2024.2370511] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Accepted: 06/10/2024] [Indexed: 06/26/2024]
Abstract
OBJECTIVES Emergency medical services (EMS) serves a critical role in the delivery of services to children with out-of-hospital emergencies. The EMS clinicians' initial field diagnoses, termed "impressions," facilitate focused patient assessments, guide the application of prehospital treatment protocols, and help determine transport destination. We sought to evaluate the concordance of the EMS clinician impression to a child's hospital-based diagnosis. METHODS We retrospectively studied de-identified pediatric (<18 years old) scene runs transported to the hospital and with available linked hospital data from the 2021 ESO Data Collaborative, a multi-agency prehospital electronic health record dataset. EMS impressions and primary emergency department or admission-based diagnoses were categorized into one of twenty-one major groups in the Diagnosis Grouping System. We identified the most common hospital-based discharge diagnoses and evaluated for the agreement between EMS impression and hospital-based diagnosis using Cohen's Kappa statistic. RESULTS We included 35,833 pediatric transports from the scene with linked prehospital and in-hospital data (median age 11 years, interquartile range, 3-15 years; 50.9% male). The most common categories for both EMS impressions and hospital-based diagnoses were as follows respectively: trauma (26.1%; 24.6%), neurologic diseases (18.9%; 16.4%), psychiatric and behavioral diseases and substance use disorder (11.8%; 11.6%), and respiratory diseases (11.1% and 9.5%). A total of 23,224 out of 35,833 patients, or 64.8%, had concordant EMS impressions and hospital-based diagnoses. There was high agreement between common EMS impression and in-hospital diagnoses (trauma 77.3%; neurologic diseases 70.3%; respiratory diseases 64.5%; and psychiatric, behavioral disease and substance use disorder 73.9%). Hospital-based diagnoses demonstrated moderate concordance with prehospital data (Cohen's κ = 0.59). CONCLUSIONS We found moderate concordance between EMS primary impression and hospital diagnoses. The EMS encounter is brief and without capabilities of advanced testing, but initial impressions may influence the basis of the triage assignment and interventions during the hospital-based encounter. By evaluating EMS impressions and ultimate hospital diagnoses, pediatric protocols may be streamlined, and specific training emphasized in pursuit of improving patient outcomes. Future work is needed to examine instances of discordance and evaluate the impact on patient care and outcomes.

Development of neffy, an Epinephrine Nasal Spray, for Severe Allergic Reactions. Pharmaceutics 2024; 16:811. [PMID: 38931932 PMCID: PMC11207568 DOI: 10.3390/pharmaceutics16060811] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Revised: 06/04/2024] [Accepted: 06/08/2024] [Indexed: 06/28/2024] Open
Abstract
Epinephrine autoinjectors (EAIs) are used for the treatment of severe allergic reactions in a community setting; however, their utility is limited by low prescription fulfillment rates, failure to carry, and failure to use due to fear of needles. Given that delayed administration of epinephrine is associated with increased morbidity/mortality, there has been a growing interest in developing needle-free, easy-to-use delivery devices. neffy (epinephrine nasal spray) consists of three Food and Drug Administration (FDA)-approved components: epinephrine, Intravail A3 (absorption enhancer), and a Unit Dose Spray (UDS). neffy's development pathway was established in conjunction with the FDA and the European Medicines Agency and included multiple clinical trials to evaluate pharmacokinetic and pharmacodynamic responses under a variety of conditions, such as self-administration and allergic and infectious rhinitis, as well as an animal anaphylaxis model of severe hypotension, where neffy demonstrated a pharmacokinetic profile that is within the range of approved injection products and a pharmacodynamic response that is as good or better than injections. The increased pulse rate (PR) and blood pressure (BP) observed even one minute following the administration of neffy confirm the activation of α and β adrenergic receptors, which are the key components of epinephrine's mechanism of action. The results suggest that neffy will provide a safe and effective needle-free option for the treatment of severe allergic reactions, including anaphylaxis.

Abstract
BACKGROUND Current clinical criteria for identifying anaphylaxis do not account for unique aspects of infant anaphylaxis presentation and have not been validated in patients younger than 2 years of age. This may contribute to under recognition and is thus an unmet need. OBJECTIVE To demonstrate age-specific signs and symptoms that more accurately identify anaphylaxis in young children and to develop and compare modified criteria for "likely anaphylaxis" against the widely used 2006 National Institute of Allergy and Infectious Diseases/Food Allergy and Anaphylaxis Network (NIAID/FAAN) criteria. METHODS Retrospective chart review of 337 clinical encounters presenting with suspected allergic or anaphylactic reactions to a pediatric emergency department. Modified criteria for likely anaphylaxis were developed and evaluated against the NIAID/FAAN criteria. RESULTS The study population included 33% infants (age < 12 mo), 39% toddlers (age 12 mo to < 36 mo), and 29% children (age ≥ 36 mo). The NIAID/FAAN criteria captured 85% of all patient encounters in the study and the modified criteria captured 98% (P < .001). Compared with NIAID/FAAN criteria, modified criteria had 22.8% improved performance among infants (p < .001) and 10.3% improved performance among toddlers (P = .04). CONCLUSIONS We developed modified anaphylaxis clinical criteria that incorporated symptoms specific to infants and young children. The modified criteria increased identification of anaphylaxis in infants and potentially toddlers. Future research is needed to validate our findings on a larger cohort.

A retrospective audit of adult and paediatric anaphylaxis management from two Australian metropolitan mixed emergency departments. BMC Emerg Med 2024; 24:67. [PMID: 38627619 PMCID: PMC11022440 DOI: 10.1186/s12873-024-00966-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Accepted: 03/11/2024] [Indexed: 04/19/2024] Open
Abstract
BACKGROUND Anaphylaxis is a potentially life-threatening allergic reaction, with presentations to emergency departments (EDs) increasing across Australia. Understanding the features of those presenting with anaphylaxis and aspects related to its optimal clinical management across the admission, treatment and discharge settings is needed to minimise its impact. We aimed to evaluate the nature and management of presentations related to anaphylaxis across two Australian EDs. METHODS Retrospective audit of paediatric and adult patients presenting to a community or tertiary level ED with anaphylaxis from 1 May 2018 to 30 April 2019. Data extracted from medical records included demographic characteristics, causative agents, clinical features, treatments administered across community, ambulance or ED settings, as well as post-discharge care arrangements including provision of Adrenaline Auto-Injector (AAI) and Allergy/Anaphylaxis Action Plan (AAP). RESULTS A total of 369 (107 paediatric and 262 adult) ED presentations were identified. A total of 94 (36%) adult and 46 (43%) paediatric patients received pre-hospital adrenaline, with a further 91 (35%) adult and 29 (27%) paediatric patients receiving a dose of adrenaline in the ED. The most commonly administered treatment in ED were corticosteroids, given to 157 (60%) adult and 55 (51%) paediatric patients. Among those requiring an AAI for discharge, 123/210 (59%) adult and 57/91 (63%) of paediatric patients left hospital with an AAI. In contrast, among those requiring an allergy/anaphylaxis action plan (AAP) on discharge, 61/206 (30%) adult and 30/90 (33%) of paediatric patients left hospital with one. Factors associated with an increased likelihood of receiving AAI on discharge in paediatric and adult patients included receipt of any adrenaline, receipt of two or more doses of adrenaline, and longer duration of hospital stay. Adults presenting within business hours were more likely to be discharged with AAI, but no such difference was observed for paediatric patients. Similar findings were evident for provision of AAP on discharge. CONCLUSION These findings demonstrate the need to improve assessment and treatment in the ED. In particular, the observed large variability in provision of AAI and AAP on discharge presents opportunities to explore strategies to improve awareness and provision of these critical components of post-discharge care.

Abstract
This practice parameter update focuses on 7 areas in which there are new evidence and new recommendations. Diagnostic criteria for anaphylaxis have been revised, and patterns of anaphylaxis are defined. Measurement of serum tryptase is important for diagnosis of anaphylaxis and to identify underlying mast cell disorders. In infants and toddlers, age-specific symptoms may differ from older children and adults, patient age is not correlated with reaction severity, and anaphylaxis is unlikely to be the initial reaction to an allergen on first exposure. Different community settings for anaphylaxis require specific measures for prevention and treatment of anaphylaxis. Optimal prescribing and use of epinephrine autoinjector devices require specific counseling and training of patients and caregivers, including when and how to administer the epinephrine autoinjector and whether and when to call 911. If epinephrine is used promptly, immediate activation of emergency medical services may not be required if the patient experiences a prompt, complete, and durable response. For most medical indications, the risk of stopping or changing beta-blocker or angiotensin-converting enzyme inhibitor medication may exceed the risk of more severe anaphylaxis if the medication is continued, especially in patients with insect sting anaphylaxis. Evaluation for mastocytosis, including a bone marrow biopsy, should be considered for adult patients with severe insect sting anaphylaxis or recurrent idiopathic anaphylaxis. After perioperative anaphylaxis, repeat anesthesia may proceed in the context of shared decision-making and based on the history and results of diagnostic evaluation with skin tests or in vitro tests when available, and supervised challenge when necessary.

Stiles SL, Sanfilippo FM, Loh R, Said M, Clifford RM, Salter SM. Contemporary trends in anaphylaxis burden and healthcare utilisation in Western Australia: A linked data study. World Allergy Organ J 2023; 16:100818. [PMID: 37780579 PMCID: PMC10534263 DOI: 10.1016/j.waojou.2023.100818] [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: 01/31/2023] [Revised: 08/16/2023] [Accepted: 09/08/2023] [Indexed: 10/03/2023] Open
Abstract
Background Anaphylaxis is a growing public health problem in Australia. To determine the extent of the problem, we linked multiple health datasets to examine temporal trends in anaphylaxis events across the health system in Western Australia (WA). Methods We identified an anaphylaxis cohort from 1980 to 2020 using linked datasets from ambulance, emergency departments, hospital inpatients and deaths. Age-standardised anaphylaxis event rates were calculated from 2010 to 2020. Dataset-specific rates for anaphylaxis were also examined, to show differences in health care utilisation. Annual percent change in rates (2010-2019) were estimated using age-adjusted Poisson regression models. Results A total of 19 140 individuals (mean age 31 years; 51% female) experienced 24 239 anaphylaxis events between 2010 and 2020. From 2010 to 2019, the average annual percent increase (95% CI) in rates was 5.3% (4.8-5.8%), from 70.3 to 113.9, with rates reducing to 76.5/100 000 population in 2020. Adolescents and young adults aged 5-14 years and 15-24 years had the greatest increase of 6.9% (5.6-8.1%) and 6.8% (5.6-8.0) respectively, with those over 25 years increasing by approximately 5% per year and children 1-4 years showing the lowest annual increase of 2.6% (1.1-4.2%). The highest absolute rates were seen in under 1 year (269.7/100 000; 2019). There has been an acceleration of trends from 2015 to 2019, underpinned by large increases in 15-24 and 25-34 years. All databases, show similar increasing trends, with ambulance attendance (33.7 per 100 000), emergency presentation (89.8 per 100 000) and hospital admissions (46.2 per 100 000), for anaphylaxis highest in 2019. However, whilst ambulance and emergency presentations have grown by 8.9% (95%CI 7.9-9.8%) and 6.6% per year (95%CI 6.0-7.2%), respectively, hospitalisations appear to be steadying with only a 0.9% (95%CI 0.2-1.6%) yearly rise. Conclusion Rates of anaphylaxis continue to increase, with WA having higher rates than previous estimates for Australia. Whilst rates are still high in infants, lower trends in children compared to older ages may indicate better prevention of allergy. Results show more people experiencing anaphylaxis now receive care in emergency and ambulance, rather than hospital. Further exploration of the patient care journey through prehospital and inpatient care is required, to understand the changing health demands of people who experience anaphylaxis.

Cavanagh N, Blanchard IE, Weiss D, Tavares W. Looking back to inform the future: a review of published paramedicine research. BMC Health Serv Res 2023; 23:108. [PMID: 36732779 PMCID: PMC9893690 DOI: 10.1186/s12913-022-08893-4] [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: 07/07/2022] [Accepted: 11/28/2022] [Indexed: 02/04/2023] Open
Abstract
OBJECTIVE Paramedicine has evolved in ways that may outpace the science informing these changes. Examining the scholarly pursuits of paramedicine may provide insights into the historical academic focus, which may inform future endeavors and evolution of paramedicine. The objective of this study was to explore the existing discourse in paramedicine research to reflect on the academic pursuits of this community. METHODS We searched Medline, Embase, CINAHL, Google Scholar and Web of Science from January, 2006 to April, 2019. We further refined the yield using a ranking formula that prioritized journals most relevant to paramedicine, then sampled randomly in two-year clusters for full text review. We extracted literature type, study topic and context, then used elements of qualitative content, thematic, and discourse analysis to further describe the sample. RESULTS The initial search yielded 99,124 citations, leaving 54,638 after removing duplicates and 7084 relevant articles from nine journals after ranking. Subsequently, 2058 articles were included for topic categorization, and 241 papers were included for full text analysis after random sampling. Overall, this literature reveals: 1) a relatively narrow topic focus, given the majority of research has concentrated on general operational activities and specific clinical conditions and interventions (e.g., resuscitation, airway management, etc.); 2) a limited methodological (and possibly philosophical) focus, given that most were observational studies (e.g., cohort, case control, and case series) or editorial/commentary; 3) a variety of observed trajectories of academic attention, indicating where the evolution of paramedicine is evident, areas where scope of practice is uncertain, and areas that aim to improve skills historically considered core to paramedic clinical practice. CONCLUSIONS Included articles suggest a relatively narrow topic focus, a limited methodological focus, and observed trajectories of academic attention indicating where research pursuits and priorities are shifting. We have highlighted that the academic focus may require an alignment with aspirational and direction setting documents aimed at developing paramedicine. This review may be a snapshot of scholarly activity that reflects a young medically directed profession and systems focusing on a few high acuity conditions, with aspirations of professional autonomy contributing to the health and social well-being of communities.

Xing Y, Wong GWK. Environmental Influences and Allergic Diseases in the Asia-Pacific Region: What Will Happen in Next 30 Years? ALLERGY, ASTHMA & IMMUNOLOGY RESEARCH 2022; 14:21-39. [PMID: 34983105 PMCID: PMC8724831 DOI: 10.4168/aair.2022.14.1.21] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Accepted: 11/14/2021] [Indexed: 12/22/2022]
Abstract
Asia-Pacific is a populous region with remarkable variations in socioeconomic development and environmental exposure among countries. The prevalence rates of asthma and allergic rhinitis appear to have recently reached a plateau in Western countries, whereas they are still increasing in many Asian countries. Given the large population in Asia, even a slight increase in the prevalence rate will translate into an overwhelming number of patients. To reduce the magnitude of the increase in allergic diseases in next few decades in Asia, we must understand the potential factors leading to the occurrence of these disorders and the development of potential preventive strategies. The etiology of allergic disorders is likely due to complex interactions among genetic, epigenetic, and environmental factors for the manifestations of inappropriate immune responses. As urbanization and industrialization inevitably progress in Asia, there is an urgent need to curtail the upcoming waves of the allergy epidemic. Potentially modifiable risk exposure, such as air pollution, should be minimized through timely implementation of effective legislations. Meanwhile, re-introduction of protective factors that were once part of the traditional farming lifestyle might give new insight into primary prevention of allergy.

Abstract
BACKGROUND There are increasing global data relating to prevalence of food allergy and food-induced anaphylaxis; however, this is often based on surrogate measures of sensitization rather than objective symptoms at food challenge. In terms of protecting food-allergic consumers from reactions, to our knowledge, there has been no global survey assessing geographic differences in the proportion of anaphylaxis triggered by specific foods. OBJECTIVE We sought to identify common triggers for food-induced anaphylaxis and how these vary from country to country. METHODS Systematic review of relevant reports published between January 2010 and November 2020. Results were reported following PRISMA guidelines. Publications were screened and data extracted by 2 independent reviewers, and the risk of bias was assessed. RESULTS Sixty-five studies (encompassing 41 countries and all 6 regions as defined by the Food and Agriculture Organization of the United Nations) were included. Significant regional variations in the most common triggers of food anaphylaxis were seen; however, in general, there was good agreement between local legislative requirements for allergen disclosure and the most common allergens for each region or nation. CONCLUSIONS Local legislation for allergen disclosure generally reflects those allergens commonly responsible for food anaphylaxis. Cow's milk and crustaceans appear to cause a higher proportion of anaphylaxis compared to peanut in some regions.

Abstract
Anaphylaxis is a systemic allergic reaction that can be caused by food, drugs, insect bites, or unknown triggers in infants and toddlers. Anaphylaxis rates are increasing. Infants and toddlers may have increased exposure to known and unknown allergens, decreased ability to describe their symptoms, and an expanded differential diagnosis for consideration on presentation. The most common symptoms in these age groups are cutaneous and gastrointestinal. Age-specific language may be helpful for caregivers to identify and describe the symptoms of anaphylaxis in infants and toddlers. Long-term management of anaphylaxis includes allergy evaluation to guide avoidance and assess prognosis and education on allergic reaction management; this incorporates the prescription of epinephrine autoinjector and provision of an allergy emergency plan.

Abstract
BACKGROUND Since few studies have analyzed time trends in pediatric anaphylaxis, including triggers and adrenaline usage, this study aimed to reveal these issues in a comprehensive analysis of pediatric anaphylaxis cases. METHODS The Aichi Medical Association performed a comprehensive survey of pediatric anaphylaxis cases aged under 15 years from 87 secondary and 25 tertiary emergency care hospitals in Aichi Prefecture (population 7.5 million), Japan. RESULTS Between April 2016 and March 2020, 3423 cases of anaphylaxis were identified. Food items were the most frequent trigger (73%), followed by exercise after food ingestion (4.3%), and drugs (2.2%). Egg (19%) and milk (17%) specifically were the most frequent among food triggers, while the largest proportional increase was observed in tree nuts from 6.0% in 2017 to 15% in 2019. Overall, 1647 (48%) cases were admitted to the hospital, of which 26 (0.8%) were admitted to the intensive care unit. Drug-induced anaphylaxis was associated with the highest admission rate (71%). Of the 2493 food-induced anaphylaxis cases, 1107 (44%) were treated with adrenaline. Among them, 343 cases included previously prescribed adrenaline auto-injectors (AAI), with 225 (66%) usages prior to hospital arrival. There was no significant difference in the admission rate between the cases in which AAIs were used and those with adrenaline administered in the hospital (68% and 72%, respectively). CONCLUSIONS The proportion of tree nuts in food-induced anaphylaxis increased significantly. Although prehospital AAI use has become widespread, it was not associated with lower admission rate compared to in-hospital adrenaline usage.

Abstract
PURPOSE OF REVIEW Epinephrine is the agreed-upon first line treatment for anaphylaxis, yet it continues to be underused by patients/caregivers and providers alike. RECENT FINDINGS There are unfortunately limited data on how epinephrine can best be utilized in anaphylaxis, which hinders how best to inform patients and providers. Studies reporting underuse suggest various barriers and themes on why this may happen. SUMMARY Continued education of patients, caregivers, and providers is needed; however, is not likely to be enough to close the gap. Thus, novel studies on how to increase use; increase availability in a cost-effective manner; and newer, effective delivery routes are still needed.

Abstract
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.

Abstract
PURPOSE OF REVIEW Infant anaphylaxis has been increasing in incidence; however, significant gaps in the literature remain. The aim of this article is to review the most recent literature pertaining to infant anaphylaxis and discuss recent findings related to epidemiology, diagnosis, management, and prevention. RECENT FINDINGS There is no accurate report of the incidence and prevalence of anaphylaxis in infancy. Food is the most common trigger for infant anaphylaxis reported. The diagnosis of anaphylaxis in infants is often missed, and, even when the diagnosis is made, epinephrine continues to be under-utilized. An epinephrine autoinjector with a shorter needle and lower dose is now available for infants. Concise criteria specifically focusing on infant anaphylaxis is needed to streamline its diagnosis and management. Diagnosis is underrecognized in infants leading to improper treatment. When the diagnosis is made, epinephrine continues to be under-utilized and under-prescribed in infants.

Abstract
Objectives: Although the factors driving emergency department demand have been extensively investigated, a comparatively minimal amount is known about the factors that are driving an increase in emergency ambulance demand. Methods: We conducted a retrospective observational study of consecutive cases attended by Ambulance Victoria in Melbourne, Australia from 2008 to 2015. Incidence rates were calculated, and adjusted time series regression analyses were performed to assess the driving factors of ambulance demand. Results: A total of 2,443,952 consecutive cases were included. Demand grew by 29.2% over the 8-year period. The age-specific incidence increased significantly over time for patients aged < 60 years, but not for patients aged ≥ 60 years. After adjustment for seasonality and population growth, demand increased by 1.4% per annum (incident rate ratio [IRR] = 1.014 [1.011-1.017]). The largest annual growth in demand was observed in patients with a history of mental health issues (IRR = 1.058 [1.054-1.062]), alcohol/drug abuse (IRR = 1.061 [1.056-1.066]), or a Charlson Comorbidity Index [CCI] score ≥ 4 (IRR = 1.045 [1.039-1.051]). Cases involving patients of relative socio-economic/educational disadvantage, younger age, or with no preexisting health conditions according to the CCI also grew faster than the overall patient population. Cases requiring transport to hospital increased by 1.2% annually (IRR = 1.012 [1.009-1.016]), although patients not requiring medical intervention from paramedics increased by 6.7% annually (IRR = 1.067 [1.063-1.072]). Conclusions: Increases in ambulance demand exceeded population growth. Emergency ambulances were increasingly utilized for transport of patients who did not require medical intervention from paramedics. Identifying the characteristics of patients driving ambulance demand will enable targeted demand management strategies.

Abstract
BACKGROUND Despite an increasing number of publications from individual countries and regions, there is still no systematic review of the global epidemiology of anaphylaxis in the general paediatric population. METHODS We conducted a systematic review, using a protocol registered and published with the international prospective register of systematic reviews (PROSPERO). Results were reported following PRISMA guidelines. The search strategy was designed in Medline (ovid) and modified for Embase (ovid) and PubMed. Papers were screened by two independent reviewers following selection and exclusion criteria. Data extraction and risk of bias assessment were completed by the same two reviewers. Studies in adults only or those that did not report data in children separately were excluded. RESULTS A final total of 59 articles were included. Of these, 5 reported cumulative incidence, 39 reported incidence rate and 17 reported prevalence data. The incidence of anaphylaxis in children worldwide varied widely, ranging from 1 to 761 per 100 000 person-years for total anaphylaxis and 1 to 77 per 100 000 person-years for food-induced anaphylaxis. The definition of anaphylaxis from NIAID/FAAN was the most commonly used. Gender and ethnicity were demographic risk factors associated with anaphylaxis in children. Increasing total or food-induced anaphylaxis incidence over time was reported by 19 studies. CONCLUSION The reported incidence of anaphylaxis in children varied widely. Studies in developing countries are underrepresented. To accurately compare anaphylaxis incidence between countries and investigate the time trends, further studies using a standardized definition across different countries are required.

Abstract
Introduction:Anaphylaxis is a serious, life-threatening systemic allergic reaction that may occur in individuals not previously diagnosed with an allergy. Emergency first-line treatment of choice for acute anaphylaxis is intramuscular administration of epinephrine via an auto-injector. In the school setting, students with known allergies typically keep or carry an epinephrine auto-injector (EAI). For students who do not have a known allergy or for those whose personal EAIs are unavailable, an anaphylactic event could have serious adverse outcomes if an EAI is not available via an undesignated stock supply in the school. Methods:We searched the published literature from 2000 through 2018 in CINAHL, MEDLINE, and PubMed using the following search terms: anaphylaxis, school setting, epinephrine auto-injector, and food allergies. Throughout this article, undesignated stock EAIs, stock EAIs, EAI stock, and open-order EAIs are used interchangeably. Conclusion:Anaphylaxis is increasing worldwide as the incidence of food allergies increases. Although stock EAIs for students in schools can have important benefits, the availability of EAIs in the school setting is limited. Barriers to undesignated stock EAIs include the lengthy administrative process for developing school policies and protocols; gaps in nurses' self-perceived knowledge versus objective knowledge on the topic of anaphylaxis; limited resources in many school districts; and complex role demands, lack of confidence in trained staff, or insufficient school nurse staffing. It is important that epinephrine be readily available in schools. Barriers to facilitating stock EAIs include those that can be addressed directly by nurses and those that may require policy changes. Nurses, particularly those working in school settings or pediatrics, could take the lead in discussions about the benefits of stock EAIs in schools, advocating for policy changes as warranted. Fully informed nurses can be better prepared to serve as advocates in ensuring that EAIs are available in school settings.

Dubus JC, Lê MS, Vitte J, Minodier P, Boutin A, Carsin A, Viudes G, Noel G. Use of epinephrine in emergency department depends on anaphylaxis severity in children. Eur J Pediatr 2019; 178:69-75. [PMID: 30269250 DOI: 10.1007/s00431-018-3246-3] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Revised: 09/07/2018] [Accepted: 09/10/2018] [Indexed: 01/17/2023]
Abstract
Despite multiple recommendations, intramuscular epinephrine is poorly prescribed in emergency department receiving pediatric anaphylaxis. To evaluate the role of severity symptoms on this use, we included all admissions for a diagnosis linked to possible allergy in the two pediatric emergency departments of our institution between January 2010 and December 2015. Selection and analysis were restricted to children under 18 years fulfilling Sampson's criteria for anaphylaxis. We retrospectively ranked these admissions with the Ring and Messmer anaphylaxis severity score and compared the use of epinephrine according to this classification. Among 422,483 admissions, 204 (0.05%) fulfilled the anaphylaxis criteria (170 (83.3%) grade II anaphylaxis, and 34 (16.7%) grade III; mean age 7.9 years). Previous allergy, anaphylaxis, and asthma were found in respectively 60.8%, 36.8%, and 35.1%. Food allergy was the main suspected causal trigger. Epinephrine was used in 32.7% (n = 65/199), before admission (11.4% (n = 23/201)) or in the emergency department (22.2% (n = 45/202)). Epinephrine was more frequently prescribed in grade III than in grade II anaphylaxis (84.8% vs 22.3%, p < 0.001; OR = 19.05 [7.05-54.10]). Upon discharge, epinephrine auto-injectors prescription and allergy referral were rare (31.7% and 44.2%).Conclusion: Pediatricians intuitively adapt their epinephrine use to the severity of the anaphylaxis and contribute to epinephrine underuse in pediatric anaphylaxis. What is known: • Intramuscular epinephrine is the recommended treatment for pediatric anaphylaxis. However, most of the European and North-American studies show a low prescription rate of epinephrine in both prehospital and pediatric emergency department management. • Reasons for such a low prescription rate are unknown. What is new: • This study confirms that intramuscular epinephrine is poorly prescribed in pediatric anaphylaxis (about one case among 10 before admission and one among 5 in pediatric emergency departments). • Despite recommendations, pediatricians intuitively adapt their prescription to the clinical severity of anaphylaxis, with a fourfold increase prescription in grade III compared to grade II anaphylaxis. This medical behavior ascertainment may be in part explained by the delay between the ED admission/management and the anaphylactic episode onset.

Epinephrine in Severe Allergic Reactions: The European Anaphylaxis Register. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2018; 6:1898-1906.e1. [PMID: 29606638 DOI: 10.1016/j.jaip.2018.02.026] [Citation(s) in RCA: 62] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 11/16/2017] [Revised: 02/19/2018] [Accepted: 02/25/2018] [Indexed: 10/17/2022]
Abstract
BACKGROUND Current guidelines recommend intramuscular administration of epinephrine as the first-line drug for the emergency treatment of severe allergic reactions (anaphylaxis), but no randomized trial evidence supports this consensus. OBJECTIVE We aimed to assess anaphylaxis treatment practices over 10 years, covering several European regions, all allergen sources, and all age groups. METHODS The European Anaphylaxis Register tracks elicitors, symptoms, emergency treatment, diagnostic workups, and long-term counseling for anaphylaxis incidents through web-based data entry from tertiary allergy specialists, covering information from the emergency respondent, patient, tertiary referral, and laboratory/clinical test results. RESULTS We analyzed 10,184 anaphylaxis incidents. In total, 27.1% of patients treated by a health professional received epinephrine and, in total, 10.5% received a second dose. Successful administration was less frequent in German-speaking countries (minimum 19.6%) than in Greece, France, and Spain (maximum 66.7%). Over the last decade, epinephrine administration from a health professional almost doubled to reach 30.6% in 2015-2017, half of which was applied intramuscularly. A total of 14.7% of lay- or self-treated cases were treated with an autoinjector. Of those without treatment, 22.4% carried a device for administration. No change in successful administration by lay emergency respondents was found over the last 10 years. Of the reaction and patient characteristics analyzed, only clinical severity considerably influenced the likelihood of receiving epinephrine, with 66.9% of successful administrations in near-fatal (grade IV) reactions. CONCLUSIONS Despite clear recommendations, only a small proportion of anaphylaxis incidents are treated with epinephrine. We demonstrated a slight increase in treated patients when handled by professionals, but stagnation in lay- or self-treated anaphylaxis. The reaction circumstances, the respondent's professional background, and patient characteristics did not explain which reactions were treated.
