[EPIPEN INSTRUCTIONS FOR ANAPHYLAXIS PATIENTS DURING DISPENSING: FACTORS RELATED TO THE QUALITY OF PHARMACISTS' INSTRUCTIONS].

BACKGROUND AND AIM: We previously reported that pharmacists working in pharmacies don't have enough knowledge and enough experience teaching anaphylaxis (An) and EpiPen use. We administered a questionnaire survey to pharmacists with experience handling EpiPen prescriptions. We investigated the relationship between the questionnaire results and the factors in the pharmacists' background regarding the explanation and guidance to patients. RESULTS: The percentage of pharmacists working in pharmacies who provided guidance using visual information and demonstrations was insufficient. Moreover, this figure decreased after the second guidance session. Objective confirmation of patient understanding was also insufficient. The results indicated that self-examination and participation in drug information sessions were important background factors for pharmacists who provided detailed guidance to patients. DISCUSSION: For appropriate long-term management of their condition, An patients must master the EpiPen technique. Pharmacists' guidance plays a critical role in this regard. A support system should be established for proper instruction of pharmacy patients by improving pharmacists' self-education and other educational opportunities.

Analysis of adrenaline autoinjectors acquisition in Portugal over 15 years.

Summary: Background. The adrenaline autoinjector (AAi) is universally recommended as the first-line treatment for anaphylactic reactions occurring outside the medical setting. The quantification of its acquisition may help estimate the prevalence of patients at risk of anaphylaxis with an indication for AAi. Objective. Evaluation of the global and regional frequency of AAi purchases in Mainland Portugal between 2003-2017 and calculate the inherent costs in 2017. Methods. AAi acquisition distribution analysis along this period. The population was divided in two age groups according to the adrenaline dosage. Results. A total of 10,993 AAi units of 0.15mg/0.3mL and 28,619 of 0.3mg/0.3mL were acquired in these 15 years, with an annual average of 733 and 1908 units, respectively. In cumulative values terms, Lisbon showed the highest number of AAI acquired and higher prevalence per region/100,000 inhabitants in both groups. In 2017, the annual cost for each age group was 64,202.71 € 187,447.70 € for patients and € 37,706.35 / 110,113.30 € for the National Health System. Conclusions. In the last 15 years, there was a progressive increase in AAi acquisition. We estimate a rate of anaphylaxis occurrence in Portugal according to AAi aquisition of 0.165%.

Anaphylaxis and onsite treatment in schools, kindergartens, and nurseries.

BACKGROUND: There have been no reports on both anaphylaxis incidence rate in schools, kindergarten, and nurseries, or how teachers have treated these children. This study was a fact-finding survey aimed at determining if appropriate responses to anaphylaxis onset were implemented in Oita Prefecture, Japan. METHODS: The Oita Prefectural Allergy Control Committee administered a questionnaire using Google forms to all public and private schools, public and private kindergartens, certified child-care facilities, and day-care centers in the prefecture. RESULTS: Responses to the questionnaire were obtained from 597 institutions, of which 125 890 children were affiliated with the responding institutions. Forty-eight children developed symptoms for which an adrenaline auto-injector was recommended in an Oita guideline. Among these children, three used the adrenaline auto-injector, three were prescribed the adrenaline auto-injector but were unable to use it, 27 were unable to use it as they were not prescribed an adrenaline auto-injector, and the final 15 responded that they handled their symptoms via another method because none of the above options apply. CONCLUSIONS: Most children who developed symptoms which an adrenaline auto-injector was recommended had no prescription for an adrenaline auto-injector. There is thus a need for appropriate response training to anaphylaxis whether or not an adrenaline auto-injector was prescribed.

[Food allergy at school: Personalized healthcare project and adrenaline]. / Prise en charge des allergies alimentaires en milieu scolaire en France : projet d'accueil individualisé et adrénaline.

In Europe, the prevalence of food allergy is estimated at 6-8% of children. Ten to 20% of pediatric food-induced anaphylaxis reactions occur at school. Individual healthcare plans (IHP) for food allergy aim at: identifying children at risk of allergic reactions; reducing the risk of allergen exposure; providing emergency kits containing adrenaline auto-injectors (AAI) if needed with emergency action plans and instructions about when and how to use AAI. In France, IHP were introduced into law in 2003 and was updated in 2021. The number of IHP for allergy is increasing since 10 years (50,000 IHP for allergy/year). While the recommendations of the learned societies have resulted in the national harmonization of criteria for the implementation of IHP for allergy and for the prescription of emergency kits with AAI, adrenaline remains underused. In 2019, a national policy stated that all high schools must have a provision of spare AAI in case of anaphylaxis and the promotion of school staff training about food allergy and anaphylaxis was encouraged. These recommendations should be assessed widely and allergy training should be widespread. Pharmacists play an important role to take care of food-allergic children: provision of AAI prescribed for the most at-risk food allergic patients, advice and information on AAI. The pharmacist is therefore a key player in the therapeutic education of the patient to reinforce the key messages on the efficacy and safety of adrenaline used for anaphylaxis.

Pharmacokinetic and pharmacodynamic evidence of adrenaline administered via auto-injector for anaphylactic reactions: A review of literature.

Anaphylaxis is a severe allergic reaction that can lead to death if not treated quickly. Adrenaline (epinephrine) is the first-line treatment for anaphylaxis and its prompt administration is vital to reduce mortality. Following a number of high-profile cases, serious concerns have been raised, both about the optimal dose of intramuscular adrenaline via an auto-injector and the correct needle length to ensure maximal penetration every time. To date, the public data are sparse on the pharmacokinetics-pharmacodynamics of adrenaline administered via an auto-injector. The limited available literature showed a huge variation in the plasma concentrations of adrenaline administered through an auto-injector, as well as variations in the auto-injector needle length. Hence, delivering an effective dose during an anaphylaxis remains a challenge for both patients and healthcare professionals. Collaborative work between pharmacokinetics-pharmacodynamics experts, clinical triallists and licence holders is imperative to address this gap in evidence so that we can improve outcomes of anaphylaxis. In addition, we advise inclusion of expertise of human factors in usability studies given the necessity of carer or self-administration in the uniquely stressful nature of anaphylaxis.

Anaphylaxis at school. Are we prepared? Could we improve?

INTRODUCTION AND OBJECTIVES: Food allergy is a highly prevalent disorder. Anaphylaxis is the most serious consequence, and reactions often occur in schools. In the event of anaphylactic reaction prompt treatment is key and should be initiated by school personnel. The aim of this study was to assess the level of knowledge of the management of anaphylaxis, and to determine if it improves after a training session among school staff. MATERIALS AND METHODS: Descriptive study carried out by means of a pre-and post-training questionnaire completed by participants before and after a training session held at the school. Data from the same participants before and after the educational session were compared using McNemar's test. RESULTS: Three schools were enrolled (with a total of 38 children with food allergy) and 53 participants (85% teachers, 15% canteen staff) were trained. In the pre-training surveys, 83% said they had a Student's Allergic Reaction Management Plan, 56% had met with parents, 83% recognised some symptoms of allergic reaction but only 41% recognised anaphylaxis, 16% knew when to use adrenaline, 15% knew how to use it and 19% knew how to act after administering it. In the post-training questionnaires, 100% were satisfied and believed they had improved their knowledge, 93% recognised anaphylaxis and 95% the treatment of choice. CONCLUSIONS: Prior to the intervention their knowledge was insufficient, but it improved considerably after simple training. It also increased the confidence of the staff, which will be decisive when responding to an anaphylactic reaction. We believe that a compulsory training programme should be implemented universally in all schools.

Adrenaline Auto-injector injuries to digits; a systematic review and recommendations for emergency management.

AIMS: Accidental injury to digits with Adrenaline Auto-injectors (AAIs) is becoming increasingly common. Digital AAI injury causes painful ischaemia that can lead to necrosis and patient anxiety. There is a lack of understanding amongst surgeons regarding how to manage these injuries. We aimed to determine an optimal treatment algorithm for their management. METHODS: We conducted a systematic review using the search engines MEDLINE, PubMed, EMBASE, CINAHL, BNI, AMED, Google Scholar. Search items included ("epinephrine OR adrenaline") AND ("Digit" OR "Finger" OR "Thumb") AND ("Injury" OR "Accidental"). RESULTS: A total of 49 articles were identified describing 111 cases. In 58 cases; 52% of cases were managed with phentolamine, 24% were managed with nitroglycerine and 7% were treated with warm soaks. The remaining 17% of cases were managed with a variety of alternative treatments. Mean recovery time following treatment with phentolamine infiltration was 33 min, whilst symptoms persisted for several hours in some cases with observation/warm soaks and nitroglycerine. Phentolamine was more effective when injected into the AAI puncture site (mean resolution time: 17 min) in comparison to injection as a digital block (74 min). CONCLUSION: Phentolamine is the most effective method of reversing symptoms and treating ischaemic digits when compared to alternative therapies. Symptoms resolved much quicker when phentolamine was infiltrated into the site of injury compared to being infiltrated as a digital block. We propose a treatment algorithm for management of these injuries. Hand surgeons should be aware of AAI injuries and be able to advise on their management.

Anaphylaxis - acute and long-term management.

Anaphylaxis is a serious, potentially lifethreatening condition, and all healthcare professionals should be aware of it. Prompt recognition of anaphylaxis signs and early initiation of adequate treatment are essential for successful acute management. The firstline treatment is the administration of intramuscular adrenalin, followed by other interventions. Patients should be moni tored after recovery for possible biphasic reaction. Before discharge, the individual risk of further reaction should be assessed and where appropriate an adrenalin autoinjector should be prescribed. Allergy specialist followup is essential for the identification of possible triggers and cofactors. Elimination of these factors reduces the risk of future reactions. Useful preventive measure is allergen immunotherapy, which is definitely indicated in patients with anaphylaxis induced by an insect sting.

Surveillance of the use of adrenaline auto-injectors in Japanese children.

BACKGROUND: The appropriate usage of an adrenaline auto-injector (AAI, Epipen®) is a key aspect of patient and social education in the management of anaphylaxis. However, although AAIs are being prescribed increasingly frequently, there are few reports on their actual use. METHODS: The Anaphylaxis Working Group of the Japanese Society of Pediatric Allergy and Clinical Immunology requested that society members register cases in which AAIs were used. Two hundred and sixty-six cases were collected from March 2014 to March 2016. RESULTS: The cases included 240 events of immediate-type food allergies caused by cow's milk (n = 100), hen's egg (n = 42), wheat (n = 40), and peanuts (n = 11). Exercise-related events were reported in 19 cases; however, the diagnosis of food-dependent exercise-induced anaphylaxis with a specific causative food was only made in 4 cases (wheat, n = 2; fish, n = 1; squid, n = 1). The frequent reasons for the causative intake included programmed intake (n = 48), failure to check the food labeling (n = 43), and consuming an inappropriate food (n = 26). AAIs were used at schools or nurseries in 67 cases, with school or nursery staff members administering the AAI in 39 cases (58%). On arriving at the hospital, the symptom grade was improved in 71% of the cases, while grade 4 symptoms remained in 20% of the cases. No lethal cases or sequelae were reported. CONCLUSIONS: AAIs were used effectively, even by school teachers. The need to visit a hospital after the use of an AAI should be emphasized because additional treatment might be required.

Identifying the factors and root causes associated with the unintentional usage of an adrenaline auto-injector in Japanese children and their caregivers.

BACKGROUND: The unintentional usage of adrenaline auto-injectors may cause injury to caregivers or patients. To prevent such incidents, we assessed the causative factors of these incidents. METHODS: The Anaphylaxis Working Group of the Japanese Society of Pediatric Allergy and Clinical Immunology requested that society members register cases in which adrenaline auto-injectors were unintentionally used. One hundred cases were reported from June 2015 to March 2016. We identified the root causes of 70 child and 25 adult cases, separately. RESULTS: The incidents occurred with repeated prescriptions as well as the first prescription. Three cases resulted in a failure to administer an adrenaline auto-injector to children with anaphylaxis. Four caregivers used it with improper application (epilepsy or enteritis). Among the child cases, the median age at the time of the incident was 5.5 years (range, 2-14 years). Five children injected the adrenaline auto-injector on their own body trunk. Twenty children were not the allergic patients themselves. Improper management protocol of the device and the child's development were concomitantly involved in most of the cases. A variety of human behaviors were identified as the root causes in the adult cases. At least 34 cases were associated with mix-ups between the actual and training device. CONCLUSIONS: Health workers should provide sufficient education regarding safety use of adrenaline auto-injector for caregivers tailored to their experience levels at both first and repeated prescriptions. Such education must cover anticipatory behavior based on normal child development. Devices should also be further improved to prevent such incidents.

Adrenaline in anaphylaxis treatment and self-administration: experience from an inner city emergency department.

BACKGROUND: Anaphylaxis is a life-threatening emergency of which reliable epidemiological data are lacking. This study aimed to analyze how quickly patients presenting with anaphylaxis were treated in emergency and whether treatment followed the European Academy of Allergy and Clinical Immunology (EAACI) guidelines. METHODS: Patient data were collected between April 2009 and April 2013. Emergency doctors completed a questionnaire for adult patients presenting at the emergency department (ED) of the St. Pierre hospital in Brussels with anaphylaxis. Inclusion criteria were based on the Sampson criteria of anaphylaxis. Data were analyzed using a Microsoft Excel database. RESULTS: About 0.04% (100/230878) of all emergency visits in adults presented with anaphylaxis. 64% of patients received their first medical help later than 30 min after symptom onset. 67% of patients received adrenaline, 85% oral antihistamines, and 89% received IV glucocorticosteroids. 46/100 patients were discharged directly from the ED, of which 87% received further medical prescriptions for self-administration: 67% corticosteroids, 83% antihistamines, and 9% intramuscular adrenaline. 74% were instructed to consult an allergologist for adequate diagnosis. 54/100 patients were hospitalized. CONCLUSION: The majority of patients were treated according to the EAACI guidelines for management of anaphylaxis, but only a minority received the recommended adrenaline auto-injector for self-administration at discharge. Because the majority of patients received medical help later than 30 min after symptom onset, adrenaline auto-injector prescription is a necessity. The low rate of doctors prescribing adrenaline auto-injectors in the ED setting underlines the need to train doctors of various backgrounds in prevention and treatment of anaphylaxis and the close collaboration with allergologists.

Long-Term Follow-Up of Children after Venom Immunotherapy: Low Adherence to Anaphylaxis Guidelines.

BACKGROUND: Data on the long-term outcome of children after specific venom immunotherapy (VIT) are limited. Therefore, we assessed sting recurrence and anaphylaxis relapse rates as well as adherence to anaphylaxis guidelines with regard to the availability of emergency equipment and education status. METHODS: For this long-term survey, data of 311 children with a history of anaphylactic reactions to hymenoptera stings were collected by chart review. We included patients who were treated with a 3-year VIT between 1993 and 2009 and had completed a questionnaire. RESULTS: Forty of the 311 patients were included. Mean VIT duration was 3.1 years. Of the 40 patients included, 29 children (72.5%) received VIT with vespid venom, 9 with bee venom, and 2 patients with both venoms. During a mean follow-up period of 13 years, 20/40 patients (50%) suffered re-stings. Six of the 20 (30%) patients developed again anaphylactic symptoms (grade 1 n = 5, grade 3 n = 1); 2 were allergic to vespid and 4 to bee venom. Of the entire cohort, only 5/40 (12.5%) had appropriate emergency kits according to the guidelines of the European Academy of Allergy and Clinical Immunology. Among the patients who had emergency kits available, one third (5/15) felt uncertain about the correct application of the medication. Less than two thirds of our population (25/40) affirmed that they have been educated in emergency management. The vast majority (95%; 38/40) of our patients did not have allergy follow-ups after VIT completion. CONCLUSIONS: Anaphylactic relapses are not uncommon, and there are considerable deficits in the emergency management of patients. Hence, comprehensive standardized anaphylaxis education programs as well as regular follow-ups of the allergy status are crucial.

Community healthcare professionals overestimate the risk of fatal anaphylaxis for food allergic children.

BACKGROUND: Fatal food anaphylaxis is rare, but a major concern for people with food allergy and their carers. We evaluated whether community healthcare professionals accurately estimate risk of fatal anaphylaxis for food allergic children, and whether accurate risk estimation is related to competence in recognizing and managing anaphylaxis. METHODS: We enrolled 90 community healthcare professionals in a cross-sectional survey - 30 primary care nurses, 30 school first aiders, 30 community pharmacists. Participant risk estimates for fatal and non-fatal anaphylaxis, and all-cause fatalities, were measured using a risk ladder. Participant anaphylaxis knowledge was assessed by questionnaire, and practical skills using a simulated anaphylaxis scenario. RESULTS: In all three groups, participants significantly overestimated the risk of fatal anaphylaxis for food allergic children, by a mean factor of 13.5-fold (95% CI 5.0, 31.6), but did not overestimate non-fatal anaphylaxis risk or all-cause fatality risk. We found no evidence of a relationship between successful adrenaline administration and risk estimation. CONCLUSIONS AND CLINICAL RELEVANCE: In conclusion, we have found evidence that community pharmacists, school first aiders and primary care nurses in the UK systematically overestimate the risk of fatal anaphylaxis for a food allergic child. This overestimation may result in increased patient and carer anxiety. Community practitioners who manage childhood food allergy and anaphylaxis need to be educated about the level of risk for fatal anaphylaxis in such children.

Factors impacting parental burden in food-allergic children.

AIM: This study aims to determine factors impacting the parental burden in immunoglobulin E (IgE)-mediated food-allergic children (FAC), focusing on attitudes towards adrenaline autoinjectors (AAIs). METHODS: Questionnaires were sent to parents of diagnosed IgE-mediated FAC attending follow-up allergy clinic appointments at two Sydney hospitals in May-September 2013. The questionnaires ascertained parental attitudes, confidence and knowledge regarding AAIs and included the validated, Food Allergy Quality of Life-Parental Burden (FAQL-PB) questionnaire. RESULTS: The response rate was 68%. Of FAC, 62% were male aged 1-17 years (median 6.0). There was a high proportion of children with multiple food allergies (52% allergic to >2 foods), coexistant eczema (85%) and asthma (54%). Sixty-three per cent reported a past history of anaphylaxis and 42% reported reactions in the last 6 months. AAI had been prescribed for 84%. FAC with a history of anaphylaxis were more likely to have had an AAI prescribed (P < 0.0001). There was no difference in FAQL-PB mean scores with age or AAI prescription status. The PB score was greater if the parent had administered the AAI (P = 0.02) and where the child was allergic to >2 foods (P < 0.0001).The Ninety per cent of parents reported that the AAI increased or did not change the child's quality of life, the family or FACs freedom. Three per cent of parents whose FAC children were prescribed an AAI reported increased stress related to AAI prescription. CONCLUSION: Severity of food allergy, number of food allergens and past anaphylaxis rather than prescription of an AAI appear to be major influences on parental burden.

A workshop with practical training for anaphylaxis management improves the self-efficacy of school personnel.

BACKGROUND: School personnel are required to guarantee a secure school environment for children suffering from severe food allergies. We organized a workshop for school personnel to learn the appropriate management of anaphylaxis that included practical training with an adrenaline auto-injector (AAI). The objective of this study was to evaluate the workshop in terms of the improvement of self-efficacy (SE) of participants to deal with anaphylaxis. METHODS: All 93 school nurses, 73 schoolteachers and 110 childcare workers participating in the study completed a questionnaire before and after the workshop. The SE of the participants was evaluated using an original 15-item questionnaire. RESULTS: Before the workshop, the SE of school nurses was the highest among the profession groups, and being involved with children prescribed an AAI was a common factor associated with a high SE. After the workshop, the SE increased in all groups, but most apparently in school nurses and those involved with children prescribed an AAI. The presence of an emergency plan was positively associated with the SE of schoolteachers only after the workshop, even though no such association existed beforehand. CONCLUSIONS: Practical instruction of school nurses and school personnel involved with children prescribed an AAI resulted in dramatic improvement of the SE. These people are expected to play a central role in the development of an anaphylaxis management plan in their schools.

Comparison of adrenaline auto-injector devices: ease of use and ability to recall use.

BACKGROUND: A limited number of adrenaline auto-injectors are currently available. Epipen and Anapen are available in Australia, New Zealand, UK and parts of Europe and Asia. Few studies have compared the performance of these devices. OBJECTIVE: To compare the intuitiveness of use of these devices. A secondary aim was to compare the ability to recall the use of each device after a period of 3 months. METHOD: A random sample of 100 subjects naïve to both the EpiPen and Anapen were recruited from staff and families attending Royal Children's Hospital, Melbourne Australia. Subjects were randomized to Anapen (n = 53) or EpiPen (n = 47) and asked to demonstrate use of a 'trainer' device (i) prior to and (ii) after receiving training in its correct use. A subset (n = 32) participated in a follow-up study to evaluate (iii) the ability to recall correct use of each device. RESULTS: Most subjects correctly demonstrated all steps in use of the EpiPen and Anapen both prior to (89% vs. 79%, p = 0.17) and after training on use (100% vs. 100%). However, after 3 months, significantly more participants correctly demonstrated use of EpiPen (87%) compared to Anapen (35%) (p = 0.003) and critical errors that would likely result in failure to administer adrenaline were more common with Anapen (59% vs. 13%, p = 0.01). CONCLUSION: Most study participants correctly demonstrated the use of both devices without prior training. There was greater attrition in correct use of Anapen compared to EpiPen over time. Critical errors in administration were more likely with Anapen than EpiPen.

Evaluation of a video training program's impact on primary teachers' knowledge of allergies and skills in using an adrenaline autoinjector during the 2021-2022 school year.

AIM: The aim of the study was to assess the impact of a video training program (VTP) on primary school teachers' skills in using an adrenaline auto-injector (AAI), in correlation with knowledge regarding allergies, in cases of anaphylaxis. METHODS: A questionnaire on teachers' knowledge of allergies and on their level of confidence in using an AAI was distributed in primary schools in the French department of Manche (2173 teachers). A VTP followed this questionnaire. A second questionnaire was then distributed. Theoretical knowledge was assessed with a score out of 20. The confidence level was rated on a scale from 1 to 4. RESULTS: We collected 218 responses to the first questionnaire (10.0 % of the population included). The response rate to the second questionnaire was 4.7 % (103 participants), and from this group, 93 of the 103 participants viewed the video (90.3 %). Overall, 76 of the 218 (34.9 %) participants who completed the first questionnaire also completed the second questionnaire and watched the VTP. The number of participants who completed the whole survey was 76 (out of 2173, 3.5 %). The VTP significantly improved teachers' knowledge of the subject of allergies (the average score increased by 2.11 points, p < 0.001) as well as their confidence in recognizing the signs of a severe allergic reaction and in using an AAI: 85.4 % (n = 88) of self-confident teachers after the VTP versus 42.3 % (n = 92) before the VTP (p < 0.001). CONCLUSION: The VTP improved teachers' level of knowledge and confidence in using an AAI in cases of anaphylaxis. A similar VTP could be circulated more widely in schools to offer easy access to training tools about allergies.

Global disparities in availability of epinephrine auto-injectors.

Background: Anaphylaxis is the most severe clinical presentation of acute systemic allergic reactions and can cause death. Given the prevalence of anaphylaxis within healthcare systems, it is a high priority public health issue. However, management of anaphylaxis - both acute and preventative - varies by region. Methods: The World Allergy Organization (WAO) Anaphylaxis Committee and the WAO Junior Members Steering Group undertook a global online survey to evaluate local practice in the diagnosis and management of anaphylaxis across regions. Results: Responses were received from WAO members in 66 countries. While intramuscular epinephrine (adrenaline) is first-line treatment for anaphylaxis, some countries continue to recommend alternative routes in contrast to guidelines. Epinephrine auto-injector (EAI) devices, prescribed to individuals at ongoing risk of anaphylaxis in the community setting, are only available in 60% of countries surveyed, mainly in high-income countries. Many countries in South America, Africa/Middle-East and Asian-Pacific regions do not have EAI available, or depend on individual importation. In countries where EAIs are commercially available, national policies regarding the availability of EAIs in public settings are limited to few countries (16%). There is no consensus regarding the time patients should be observed following emergency treatment of anaphylaxis. Conclusion: This survey provides a global snapshot view of the current management of anaphylaxis, and highlights key unmet needs including the global availability of epinephrine for self-injection as a key component of anaphylaxis management.

Real World Management of Anaphylaxis Versus the National Institute for Health and Clinical Excellence (NICE) Guidelines.

Objectives  Anaphylaxis is an acute, life-threatening immediate allergic reaction caused by the sudden systemic release of mediators from mast cells. This study aims to assess the current practice of emergency management of children and adults diagnosed with anaphylaxis at the Royal Hospital, Muscat, Oman, in line with the National Institute for Health and Clinical Excellence (NICE) guidelines.  Methods This is an observational retrospective study of all anaphylaxis cases seen at the emergency department (ED) from January 2013 to January 2018 and compared with the management of anaphylaxis in the ED as per the NICE guidelines. Inclusion criteria were all patients, children (age 16 and below), and adults diagnosed with anaphylaxis based on the World Allergy Organization (WAO) criteria. Exclusion criteria are all cases labeled as anaphylaxis that did not match the WAO criteria for anaphylaxis. Results Of 100 patients with a preliminary diagnosis of anaphylaxis, 49 patients (49%) were true-anaphylaxis cases based on the WAO definition 16 were children (age 16 years and below), and 33 were adults ( age 16 years and above). The other 51 patients (51%) with misdiagnosed anaphylaxis were later diagnosed with spontaneous urticaria, septic shock, vocal cord dysfunction, severe asthma, and anxiety attack. All 49 patients with true-anaphylaxis appropriately received adrenaline intramuscularly at the ED. All 16 children were admitted, seen by an allergist, and received an adrenaline auto-injector when indicated. Only 5 of the 33 adults were admitted and seen by an allergist, and 4 of those required an adrenaline auto-injector upon discharge. The remaining 28 adults were discharged from the ED, and only 3 of these were referred to the allergist. None received an adrenaline auto-injector upon discharge from the ED, and no mention in the ED notes on patient education regarding allergen avoidance. Conclusion Third of the patients who presented to ED were children (<16 years), and two third were adults. Insect venom was the main reason for anaphylaxis in both age groups. There was an underutilization of adrenaline auto-injector prescriptions for adult patients. This could be very well improved by disseminating policies and guidelines to adult physicians.
