Skin conditions presenting in emergency room in Korea: an eight-year retrospective analysis

Global, regional, and national levels and trends in burden of urticaria: A systematic analysis for the Global Burden of Disease study 2019

Background

Urticaria places a significant burden on individuals and society due to its widespread nature. The aim of this study was to evaluate the burden of urticaria in different regions and nations by analysing data from the Global Burden of Disease study 2019 (GBD 2019), with the goal of providing information to health care policymakers.

Methods

By utilising data from the GBD 2019 database, this study analysed metrics such as incidence, prevalence, disability-adjusted life years (DALYs), age-standardised rate (ASR), and estimated annual percentage changes (EAPC) globally and across 204 countries and regions. The data was further stratified by age, sex, and sociodemographic index (SDI).

Results

In 2019, global incidence cases, prevalence cases, and overall disease burden as measured by DALYs all increased. The distribution of the burden exhibited marked geographical heterogeneity. At the regional level, the burden is highest in Central and Eastern Europe and Central Asia, with the strongest growth in South Asia, compared with a decline in the high-income Asia Pacific. At the country level, Nepal reports the highest burden of urticaria, while Portugal has the lowest. Gender and age analyses showed that the burden of urticaria is higher in females than in males, with urticaria cases declining with age, especially in children, and picking up among the elderly. The study also finds a correlation between the burden of urticaria and the SDI, with the central part of the SDI showing a consistent increasing trend.

Conclusion

This study found that the global burden of urticaria has risen from 1990 to 2019. Factors like geographic location, gender, and SDI influenced the urticaria burden. Overall, these results offer a resource to guide public health strategies seeking to reduce the burden of urticaria.

The impact of meteorological parameters on the number of applications to the emergency department with acute urticaria: A retrospective study

The study aimed to investigate the relationship between the patients who applied to the emergency department with acute urticarial and meteorological factors and determine the associated weather conditions. The relationship between acute urticaria patients who applied to the emergency department of a training and research hospital in a city with high altitude and continental climate characteristics in the eastern part of Turkey between January 2019 and December 2019 and meteorological data was evaluated retrospectively. The necessary data for the weather were obtained from the data of the Erzurum Meteorology Directorate, and the patient data were obtained from the hospital information management system and patient files. The meteorological data of the patients at the date of admission and the characteristics of the patients at that date were compared. The study identified 691 patients who applied to the emergency department diagnosed with urticaria in 2019. According to the seasons, it was observed that the patients applied most frequently in the summer months [n = 239; 34.6%]. In the univariable regression model, which was created by taking the values of weather events as a reference on the days when the urticaria presentation was not observed (Group I), it was determined that every 1-hour increase in the sunshine hour increased the probability of urticaria by 7.4% (p = 0.018). When the meteorological parameters on the days without urticaria (Group I) and the days with urticaria presentation (Group II) were compared, the sunshine hours were 7.9 (4.0-10.6) hours in Group II and 6.65 (3.3-8.85) hours in Group I (p = 0.001). Regarding relative humidity, higher humidity rates were observed in Group I compared to Group II (p = 0.009). In terms of mean temperature, daily maximum, and minimum temperature, higher temperature rates were detected in Group II (p<0.001). A relationship was determined between urticaria attacks and relative humidity and daily maximum and minimum temperature in patients who applied to the emergency department with acute urticaria.

Did the COVID-19 pandemic impact urticaria information-seeking behavior in China? A retrospective longitudinal study

Purpose

To investigate information-seeking behavior related to urticaria before and during the COVID-19 pandemic in China.

Methods

Search query data for terms related to urticaria were retrieved using Baidu Index database from October 23, 2017 to April 23, 2022, and daily COVID-19 vaccination doses data were obtained from the website of the Chinese Center for Disease Control and Prevention. Among the 23 eligible urticaria search terms, four urticaria themes were generated as classification, symptom, etiology, and treatment of urticarial, respectively. Baidu Search Index (BSI) value for each term were extracted to analyze and compare the spatial and temporal distribution of online search behavior for urticaria before and after the COVID-19 pandemic, and to also explore the correlation between search query and daily COVID-19 vaccination doses.

Results

The classification of urticaria accounted for nearly half of the urticaria queries on the internet. Regular seasonal patterns of BSI were observed in urticaria-related online search, by attaining its highest level in spring and summer and lowest level in winter. The BSIs of all urticaria themes significantly increased after the COVID-19 pandemic than that before the pandemic (all P<0.05). Xizang, Qinghai and Ningxia are the most active geographical areas for increased urticaria-searching activities after the COVID-19 pandemic. There was also a significant positive correlation between daily BSIs and daily COVID-19 vaccination doses in each urticaria theme. Cross-correlation analysis found that the search of symptom, etiology, and treatment attained their strongest correlation with daily COVID-19 vaccination doses at 11-27 days before the injection of vaccine, imply vaccination hesitation related to concerns of urticaria.

Conclusions

This study used the internet as a proxy to provide evidence of public search interest and spatiotemporal characteristics of urticaria, and revealed that the search behavior of urticaria have increased significantly after the COVID-19 pandemic and COVID-19 vaccination. It is anticipated that the findings about such increase in search behavior, as well as the behavior of urticaria-related vaccine-hesitancy, will help guide public health education and policy regulation.

The association between air pollution, meteorological factors, and daily outpatient visits for urticaria in Shijiazhuang, Hebei Province, China: a time series analysis

The associations of air pollution and meteorological factors with the outpatient visits of urticaria remain poorly studied. This study aimed to assess the association between air pollution, meteorological factors, and daily outpatient visits for urticaria in Shijiazhuang, China, during 2014-2019. Daily recordings of air pollutant concentrations, meteorological data, and outpatient visits data for urticaria were collected during the 6 years. Descriptive research methods were used to describe the distribution characteristics and demographic features of urticaria. A combination of the generalized linear regression model (GLM) and distribution lag nonlinear model (DLNM) was used to evaluate the lag association between environmental factors and daily outpatient visits for urticaria. Stratified analyses by gender (male; female) and age (< 18 years; 18-39 years; > 39 years) were further conducted. The dose-response relationship between daily urticaria visits and CO, NO₂, O₃, temperature, and relative humidity was nonlinear. High concentrations of CO, NO₂, O₃, and high temperatures increased the risk of urticaria outpatient visits. The maximum cumulative association of high concentrations of CO, NO₂, and O₃ was lag 0-14 days (CO: RR = 1.10, 95%CI: 1.06, 1.31; NO₂: RR = 1.09, 95%CI: 1.01, 1.08; O₃: RR = 1.16, 95%CI: 1.08, 1.25), and high temperatures was lag 0-7 days (RR = 1.27, 95%CI: 1.14, 1.41). Low concentrations of NO₂, O₃, and high humidity, on the other hand, act as protective factors for urticaria outpatient. The maximum cumulative association of low concentrations of NO₂ was the 0-day lag (RR = 0.97, 95%CI: 0.95, 0.99), O₃ was lag 0-5 days (RR = 0.94, 95%CI: 0.88, 0.99), and high humidity was lag 0-10 days (RR = 0.93, 95%CI: 0.89, 0.98). Stratified analyses showed that the risk of urticaria outpatient visits was higher for the males and in the < 18 years age group. In conclusion, we found that the development of urticaria in Shijiazhuang has a distinct seasonal and cyclical nature. Air pollutants and meteorological factors had varying degrees of influence on the risk of urticaria outpatient visits. This study provides indirect evidence for a link between air pollution, meteorological factors, and urticaria outpatient visits.

Analysis of Types of Skin Lesions and Diseases in Everyday Infectious Disease Practice-How Experienced Are We?

Rashes and skin lesions are a common reason for patient visits to emergency departments and physicians’ offices. The differential diagnosis includes a variety of infectious and non-infectious diseases, some of which can be life-threatening. The aim of this retrospective study was to evaluate the quantity and type of skin lesions among outpatients and inpatients at a tertiary care university-affiliated teaching hospital for infectious diseases over a three-year period to assess disease burden and physicians’ experience in diagnosing skin lesions. Diagnoses (by ICD-10 codes) were classified into three groups: infectious diseases that include skin lesions, non-infectious skin lesions and undiagnosed skin lesions. During the observed period, out of the total of 142,416 outpatients, 14.8% presented with some form of skin lesion. Among them, 68% had skin lesions inherent to infectious disease, 10.8% suffered from non-infectious skin lesions and 21.2% remained with undiagnosed skin lesions. The most common infectious diagnoses were chickenpox, herpes zoster and unspecified viral infections characterized by skin and mucous membrane lesions. The most common non-infectious diagnoses were urticaria and atopic dermatitis. Overall, the most common individual diagnosis (ICD-10 code) was “nonspecific skin eruption” (n = 4448, 21.1%), which was followed by chickenpox and herpes zoster. Among the 17,401 patients hospitalized over the observed period, 13.1% had skin lesion as the main reason for hospitalization, almost all (97.5%) of which were infectious in etiology. The most common diagnoses were cellulitis, erysipelas and herpes zoster. The presented data suggest that the burden of diseases presenting with skin lesions is significant in everyday infectious disease practice, but the overwhelming number of undiagnosed patients implies the need for further education in this area.

The effect of the COVID-19 pandemic on dermatology consultation requests from adult and paediatric emergency departments

AIM

This study aimed to determine the characteristics of dermatology consultation requests from the adult and paediatric emergency departments (EDs) of a university hospital during 8 months of the COVID-19 pandemic in 2020 and to compare them with the same 8 months of 2019.

MATERIALS AND METHODS

Electronic medical records of dermatology consultation requests from adult and paediatric EDs between 15 March 2019 and 15 November 2019, and between 15 March 2020 and 15 November 2020 were retrospectively reviewed.

RESULTS

The study included 495 consecutive dermatology consultation requests. In total, 283 (57%) consultation requests occurred in 2019, vs 212 (43%) between in 2020 during the COVID-19 pandemic. The number of consultation requests per day was significantly lower in 2020 (0.9 ± 0.1 per day) than in 2019 (1.15 ± 0.1 per day; P = .002), and was significantly lower in March, April and May 2020, as compared with March, April, and May 2019 (P = .004, P = .001, and P = .001, respectively). The median time from onset of dermatological symptoms to ED presentation was significantly longer in 2020 than in 2019 (4 days in 2019 vs 7 days in 2020; P < .001). Dermatological emergencies in 2019 and 2020 constituted 6.7% of all emergency presentations, with no significant difference between the 2 years (7.1% of all ED presentations in 2019, vs 6.1% in 2020; P = .795).

CONCLUSION

COVID-19 restrictions and fear of COVID-19 infection might have discouraged patients from presenting to EDs because of skin problems; however, the easing of COVID-19 restrictions might lead to an increase in ED presentations, including non-urgent dermatological disorders. In order to reduce unnecessary use of EDs and prevent ED overcrowding, the general public should be educated about what constitutes a dermatological emergency.

Presenting patterns of dermatology conditions to an Australian emergency department

BACKGROUND

Approximately 5%-8% of emergency department (ED) presentations are due to a dermatological condition. This study aimed to identify and characterise patients with skin conditions presenting to a busy ED.

METHODS

A 5-year retrospective study on patients with dermatological conditions presenting to the Princess Alexandra Hospital ED in Brisbane, Australia was performed. Electronic medical records were used to compare demographics and admission status of the dermatology group and the total ED group presentations. A prospective survey was conducted on low priority triage (triage 4 and 5) patients identifying reasons presenting to the ED.

RESULTS

Of a total 281,718 ED presentations, 11,748 dermatology presentations were identified between January 2012 to December 2016. Of the dermatology presentations, 41.5% were female and had an average age of 47. The most common dermatology presentations were cellulitis, abscess, rash unspecified, and ulcer. Of those admitted, 36% were female, average age was 53, mean length of stay of 294 minutes and 83.1% had an infectious aetiology. Of triage 4 and 5 presentations, 66% patients we approached had been seen by a health practitioner prior to coming to the ED.

CONCLUSION

Within the population presenting with a skin related condition to the Princess Alexandra Hospital ED, characteristics associated with admission include male sex, older age, and an infectious etiology. This data may help ED clinicians decide on the discharge disposition of these patients. There may be a role for streamlined admissions for skin related infections, or improved hospital in the home services to support this group.

Resources spent on dermatological emergency patients: A twelve-month prospective data collection from Germany

BACKGROUND AND OBJECTIVES

Rising numbers of patients consulting emergency units are associated with an increased demand for material and personnel. In order to better quantify these resources, we performed an analysis of diagnostic procedures, treatment types, and the quantity and educational level of staff involved in emergency consultations.

PATIENTS AND METHODS

The study was conducted as a prospective single-center survey over twelve months in the dermatology unit of a Germany university hospital. 3155 consultations were included by consecutive sampling.

RESULTS

Diagnostic tests (e.g. microbiological swab, blood testing, punch biopsy) were performed in 29 % of all consultations. Physicians prescribed treatment in 70 % of cases, with steroids and antihistamines being the most frequent topical and systemic treatment, respectively. Each patient was seen by at least one physician and a nurse, and in 25 % of cases an additional physician was involved. Less than thirty minutes was required for the consultation in the vast majority of cases. On average, emergency consultations required two hours per day of the treating physician's time, not including the time of other involved staff such as nurses and laboratory technicians.

CONCLUSIONS

This study demonstrates the extent of resources involved in the treatment of dermatological emergency consultations.

Emergency Consultations in Dermatology in a Secondary Referral Hospital in Southern Switzerland: A Prospective Cross-Sectional Analysis

BACKGROUND/AIMS

The spectrum of dermatological emergencies is broad. Only a few studies have assessed the profile of dermatological conditions resulting in an emergency visit in a referral hospital. We sought to assess the conditions prompting an urgent dermatological visit and to compare the diagnoses with those made during the regular scheduled encounters.

METHODS

We performed a cross-sectional study of all patients with a cutaneous problem attending our emergency consultation during a 7-month period. The study variables were gender, age, duration of symptoms, diagnosis, need for hospitalization and/or follow-up. We further evaluated patients attending scheduled visits to compare the demographic characteristics and diagnoses between the two groups.

RESULTS

Six hundred fifty-two consecutive patients with an urgent dermatological consultation were included. Three hundred sixty (55.2%) were women and 292 (44.8%) were men. Infectious diseases (32.8%) as well as various forms of eczema (24.8%) constituted the most frequent causes for an emergency visit. Approximately 40% of emergency visits took place more than 1 week after the development of the cutaneous manifestations. The most frequent disorders seen in the 1,738 control patients included benign melanocytic and nonmelanocytic tumors (27.2%) and malignant skin lesions (11.5%).

CONCLUSIONS

Our study indicates that the dermatological diagnoses in the emergency visits significantly differ from those of the routinely scheduled appointments. In a significant portion of patients, the use of an emergency consultation was not justified. This study provides support to the idea that a specific training is required to manage dermatological emergencies and that efforts should be made to reduce unjustified emergency visit use.

Dermatological conditions presenting to the emergency dermatological unit of a university hospital in Germany

BACKGROUND AND OBJECTIVES

Recently, there have been increasing numbers of patients consulting emergency units in all medical disciplines. Our aim was to analyze the demographics, referral mode, symptoms, localization of lesions, prior treatment, diagnoses and hospitalization rate of dermatological patients.

PATIENT AND METHODS

The study was conducted as a prospective single center survey over six months in the dermatology unit of a university hospital in Germany. 1552 consultations were included with consecutive sampling.

RESULTS

The study cohort had a mean age of 41 years and included 53 % females. Nearly half of the patients lived less than 10 kilometers from the study center. 72 % of patients referred themselves. The main symptoms were itching and occurrence of a rash; these symptoms had been present for more than a week on average. A general manifestation was present on the skin in most cases. 55 % of patients were seen by a dermatologist or a general practitioner before the consultation. Prior treatment had been received in 49 % of cases. Eight percent of patients were hospitalized. Eczema was the most common diagnosis, followed by urticaria and scabies.

CONCLUSIONS

This study confirms that a considerable number of patients present with non-urgent diagnoses. Careful prescreening and sensitization of the population may be necessary to reverse this trend.

Infectious skin disorders encountered in a pediatric emergency department of a tertiary care hospital in Argentina: a descriptive study

BACKGROUND

Infectious skin disorders (ISDs) are commonly seen in pediatric emergency departments (PED), however the exact frequency is unknown. We provide an accurate evaluation of the incidence and characteristics of ISDs diagnosed in a PED from Buenos Aires, Argentina, over a 1-year period.

METHODS

Prospectively, descriptive study of children evaluated in the PED with ISDs during 2016. ISDs were analyzed on the basis of their incidence, patient demographics, seasonal variations, and hospitalization rates.

RESULTS

ISDs were diagnosed in 1680 (67.9%) of the skin consultations (M/F: 1.1; mean age: 4.4 ± 3.7 years). Bacterial infections were observed in 932 (55.5%) cases. Viral infections were seen in 604 patients (35.9%). Fungal and parasite skin infections were diagnosed in 33 (2%) and 111 (6.6%) children, respectively. The most frequent ISDs according to the etiology group were impetigo 377 (22.4%), varicella 397 (23.6%), tinea capitis 10 (0.6%), and scabies 109 (6.5%). A higher frequency of ISDs were reported during the summer (38.4%) and spring (38.2%) months. Bacterial skin infections were more frequent during the summer months, while viral skin infections were more prevalent during spring. Parasitic skin infections were diagnosed more frequently during the winter months. No differences were seen for mycotic skin infections. Hospitalization rate was 1% (all for bacterial skin infections).

CONCLUSION

Our data reveal the extremely high frequency of ISDs seen at the PED, underlying the need for closer cooperation between dermatologists and pediatricians.

Dermatological conditions presenting at the Emergency Department in Siena University Hospital from 2006 to 2011

BACKGROUND

Published studies on emergency dermatology consultations are few because there are few dermatology emergency units in the world. No study has yet described the Italian situation.

OBJECTIVES

To quantify and characterize patients evaluated in our dermatology emergency unit from 2006 to 2011.

METHODS

We studied personal details, diagnosis, annual trend of cases, emergency level and hospitalization of dermatology cases over the 6-year period.

RESULTS

A total of 12,226 patients were evaluated. The most numerous diagnostic group was infections (27.1%), followed by non-specific and descriptive diagnosis (22.5%), skin conditions caused by mechanical or physical agents (13.1%), eczematous diseases (10.5%), insect bites (9.5%) and urticaria/angio-oedema (8.8%). The most common indications for admission to hospital were skin conditions caused by mechanical or physical agents (33.3%), infections (27.5%), drug eruption (15.9%) and autoimmune or inflammatory disorders (7.4%). Emergency dermatology cases followed a variable annual trend, with more consultations in the summer months.

CONCLUSION

This is the first long-term retrospective analysis of a large series of dermatology emergency patients. It provides useful quantitative and qualitative information on cases for physicians and the national health system for the purposes of improving patient care and cost-effectiveness.

Which dermatological conditions present to an emergency department in australia?

Background/Objectives. There is minimal data available on the types of dermatological conditions which present to tertiary emergency departments (ED). We analysed demographic and clinical features of dermatological presentations to an Australian adult ED. Methods. The St. Vincent's Hospital Melbourne (SVHM) ED database was searched for dermatological presentations between 1 January 2009 and 31 December 2011 by keywords and ICD-10 diagnosis codes. The lists were merged, and the ICD-10 codes were grouped into 55 categories for analysis. Demographic and clinical data for these presentations were then analysed. Results. 123 345 people presented to SVHM ED during the 3-year period. 4817 (3.9%) presented for a primarily dermatological complaint. The most common conditions by ICD-10 diagnosis code were cellulitis (n = 1741, 36.1%), allergy with skin involvement (n = 939, 19.5%), boils/furuncles/pilonidal sinuses (n = 526, 11.1%), eczema/dermatitis (n = 274, 5.7%), and varicella zoster infection (n = 161, 3.3%). Conclusion. The burden of dermatological disease presenting to ED is small but not insignificant. This information may assist in designing dermatological curricula for hospital clinicians and specialty training organisations as well as informing the allocation of dermatological resources to ED.

Acute urticaria presenting in the emergency room of a general hospital

BACKGROUND

Acute urticaria is a common disorder that often prompts patients to seek treatment in the emergency room (ER). There are few data on acute urticaria presenting in ER.

OBJECTIVES

This study aimed to provide demographic and clinical data of patients presenting with acute urticaria at an ER of an Italian general hospital covering an area of about 90,000 inhabitants. The predictive factors of the length of stay in the ER had also been investigated.

METHODS

The database of ER patients was searched for urticaria by ICD-9 code and by keywords in the diagnosis description. All the medical records of the identified patients were reviewed and the length of stay in ER was noted.

RESULTS

A total of 459 patients were admitted to ER with acute urticaria in a 1-year period corresponding to 1.01% of total ER visits and to 1.2 admission per day. Angioedema was present in 139 cases (30.3%), fever in 55 (12%). Twenty-nine patients fulfilled the criteria of anaphylaxis. Triggers could be identified in 193 cases (42%): drugs in 20.7%, insects bites (10.2%), foods (7.4%) and contact urticaria in 3.7%. Anaphylaxis (p<0.001), food (p<0.05) and drugs (p<0.05) as triggers were significant and independent predictive factors of the length of stay in ER.

CONCLUSIONS

Patients with acute urticaria are frequently referred to the emergency room, but only in a few cases urticaria is associated with severe allergic manifestations. Drug and food hypersensitivity, together with anaphylaxis, are the best predictors of the length of stay in ER.
