Common causes of emergency department visits for anaphylaxis in Korean community hospitals: A cross-sectional study.

ABSTRACT: Anaphylaxis can cause death and requires immediate management. For prevention and education programs for anaphylaxis, it is important to be aware of the common triggering factors. We investigated the triggers of anaphylaxis in the emergency departments (EDs) of community hospitals in Korea.Patients who visited the EDs of 7 community hospitals for anaphylaxis from January 1, 2012 to December 31, 2016 were enrolled. Anaphylaxis was defined according to the World Allergy Organization criteria and identified via a thorough review of the medical records of patients who were diagnosed with anaphylaxis (ICD-10 codes: T780, T782, T805, and T886) at the ED or administered epinephrine in the ED. Triggers of anaphylaxis were also evaluated by a review of the medical records.We identified 1021 ED visits for anaphylaxis. The incidence of anaphylaxis ED visits was 0.08%. The triggers of ED visits for anaphylaxis were bee venom (55.0%), foods (21.3%), and drugs (13.2%); 9.6% of cases were idiopathic. However, food was the most common trigger among the patients aged <20 years old. The frequency of ED visits for anaphylaxis was highest in summer (47.9%), followed by autumn (28.2%), spring (12.3%), and winter (11.6%). The incidence of anaphylaxis ED visits was highest in August, during which bee venom was the trigger for 80% of anaphylaxis cases. For the 55 patients with repeat ED visits for anaphylaxis, Bee venom was also the most common trigger.The number of ED visits for anaphylaxis showed marked seasonal variation, peaking in summer. Bee venom was the most common trigger for adults and the main reason for seasonal variations of anaphylaxis ED visits in Korean community hospitals.

Project description:PurposeLow-acuity pediatric emergency department (PED) visits are frequent in high-income countries and have a negative impact on patient care at the individual and health system levels. Knowing what drives low-acuity PED visits is crucial to inform adaptations in health care delivery. We aimed to identify factors associated with low-acuity PED visits in Switzerland, including socioeconomic status, demographic features, and medical resources of families.MethodsWe conducted a prospective, questionnaire-based study in the PEDs of two Swiss tertiary care hospitals, Bern and Lausanne. We invited all consecutive children and their caregiver attending the PED during data collection times representative of the overall PED consultation structure (e.g. day/night, weekdays/weekends) to complete a questionnaire on demographic features, socioeconomic status, and medical resources. We collected medical and administrative data about the visit and defined low-acuity visits as those meeting all of the following criteria: (1) triage category 4 or 5 on the Australasian Triage Scale, (2) no imaging or laboratory test performed, and (3) discharge home. We used a binary multiple logistic regression model to identify factors associated with low-acuity visits.ResultsWe analysed 778 PED visits (September 2019 to July 2020). Most children visiting our PEDs had a designated primary care provider (92%), with only 6% not having seen them during the last year. Fifty-five per cent of caregivers had asked for medical advice before coming to the PED. The proportion of low-acuity visits was 58%. Low-acuity visits were associated with caregiver's difficulties paying bills (aOR 2.6, 95% CI 1.6 - 4.4), having already visited a PED in the last 6 months (aOR 1.7, 95% CI 1.1 - 2.5) but not with parental education status, nor parental country of birth, parental employment status or absence of family network.ConclusionEconomic precariousness is an important driver for low-acuity PED visits in Switzerland, a high-income country with compulsory health coverage where most children have a designated primary care provider and a regular pediatric follow-up. Primary care providers and PEDs should screen families for economic precariousness and offer anticipatory guidance and connect those in financial need to social support.

Project description:Background and objectivesIn 2011, there were approximately 131 million visits to an emergency department in the United States. Emergency department visits have increased over time, far outpacing growth of the general population. There is a paucity of data evaluating emergency department visits among kidney transplant recipients. We sought to evaluate the incidence and risk factors for emergency department visits after initial hospital discharge after transplantation in the United States.Design, setting, participants, & measurementsWe identified 10,533 kidney transplant recipients from California, New York, and Florida between 2009 and 2012 using the State Inpatient and Emergency Department Databases included in the Healthcare Cost and Utilization Project. We used multivariable Poisson and Cox proportional hazard models to evaluate adjusted incidence rates and time to emergency department visits after transplantation.ResultsThere were 17,575 emergency department visits over 13,845 follow-up years (overall rate =126.9/100 patient-years; 95% confidence interval, 125.1 to 128.8). The cumulative incidences of emergency department visits at 1, 12, and 24 months were 12%, 40%, and 57%, respectively, with median time =19 months; 48% of emergency department visits led to hospital admission. Risk factors for higher emergency department rates included younger age, women, black and Hispanic race/ethnicity, public insurance, depression, diabetes, peripheral vascular disease, and emergency department use before transplant. There was wide variation in emergency department visits by individual transplant center (10th percentile =70.0/100 patient-years; median =124.6/100 patient-years; and 90th percentile =187.4/100 patient-years).ConclusionsThe majority of kidney transplant recipients will visit an emergency department in the first 2 years post-transplantation, with significant variation by patient characteristics and individual centers. As such, coordination of care through the emergency department is a critical component of post-transplant management, and specific acumen of transplant-related care is needed among emergency department providers. Additional research assessing best processes of care for post-transplant management and health care expenditures and outcomes associated with emergency department visits for transplant recipients are warranted.

Project description:BackgroundThe US older adult population (age ≥65 years) is increasing and may be at increased risk for severe anaphylaxis. Little is known about the health care use for acute allergic reactions (AAR), including anaphylaxis, among older adults.ObjectiveTo characterize trends in emergency department (ED) visits and hospitalizations for AAR and anaphylaxis among US older adults from 2006 to 2014 and examine factors associated with severe anaphylaxis.MethodsWe performed cross-sectional analyses of trends in ED visits and hospitalizations among older adults using data from the Nationwide Emergency Department Sample and the National (Nationwide) Inpatient Sample in 2006 to 2014. We used International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic codes to identify visits for AAR, including anaphylaxis. Multivariable logistic regression modeling was used to identify factors associated with severe anaphylaxis (cardiac arrest, intubation, and death).ResultsIn 2006 to 2014, older adults experienced approximately 1,019,967 AAR-related ED visits, 173,844 AAR-related hospitalizations, 93,795 anaphylaxis-related ED visits, and 72,677 anaphylaxis-related hospitalizations. Whereas AAR-related ED visit and hospitalization rates remained stable (P = .28 and .16, respectively), anaphylaxis-related ED visit and hospitalization rates increased significantly over time (37 visits/100,000 in 2006 to 51 in 2014, P < .001; and from 13 hospitalizations/100,000 in 2006 to 23 in 2014, P < .001), especially hospitalization rates for drug-related anaphylaxis (47 hospitalizations/100,000 in 2006 to 85 in 2014; P < .001). Risk factors for anaphylaxis-related death included older age and drug-related trigger.ConclusionsIn a nationally representative sample of US older adults, the rate of anaphylaxis-related ED visits and hospitalizations increased over time. Drug-related triggers represented a substantial portion of increased health care use and are a growing risk in this vulnerable population.

Project description:Background: Recent research has found a high rate of emergency department (ED) use after lower extremity arthroplasty; one study found a risk factor for ED presentation after lower extremity arthroplasty was presentation to the ED in the year prior to surgery. It is not known whether a similar association exists for total shoulder arthroplasty (TSA). Questions/Purposes: The goal of this study was to investigate the relationship between preoperative ED visits and postoperative ED visits after anatomic TSA. Methods: The 100% Medicare database was queried for patients who underwent anatomic TSA from 2005 to 2014. Emergency department visits within the year prior to the date of TSA were identified. Patients were additionally stratified by the number and timing of preoperative ED visits. The primary outcome measure was one or more postoperative ED visits within 90 days. A multivariate logistic regression analysis was used to control for patient demographics and comorbidities. Results: Of the 144,338 patients identified, 32,948 (22.8%) had an ED visit in the year prior to surgery. Patients with at least 1 ED visit in the year before surgery presented to the ED at a significantly higher rate than patients without preoperative ED visits (16% versus 6%). An ED visit in the year prior to TSA was the most significant risk factor for postoperative ED visits (in the multivariate analysis). The number of preoperative ED visits in the year prior to surgery demonstrated a significant dose-response relationship with increasing risk of postoperative ED visits. Conclusions: Postoperative ED visits occurred in nearly 10% of Medicare patients who underwent TSA in the period studied. More frequent presentation to the ED in the year prior to anatomic TSA was associated with increasing risk of postoperative ED visits. Future studies are needed to investigate the reasons for preoperative ED visits and if any modifiable risk factors are present to improve the ability to risk stratify and optimize patients for elective TSA.
