COVID-19 vaccination-related attendance at a pediatric emergency department in Singapore among 12- to 18-year old adolescents

Comparing the Prevalence and Characteristics of Chest Pain in Children and Adolescents Pre- and Post-COVID-19: A Retrospective Study

BACKGROUND

Chest pain is a common complaint among pediatric patients, often leading to visits to Emergency Departments or outpatient clinics. While most cases are benign, timely diagnosis is essential to prevent fatalities in those with serious conditions. The COVID-19 pandemic has shifted healthcare dynamics, necessitating an understanding of its impact on pediatric health, including potential complications such as chest pain, fever, cough, shortness of breath, sore throat, and headache. This study aims to explore the prevalence, characteristics, and potential association between COVID-19 and chest pain in children during two time periods: 2019 (before the COVID-19 pandemic) and 2021 (the full year during the pandemic).

METHODOLOGY

Data were collected from medical records and telephone interviews with pediatric patients presenting with chest pain at the University of Jordan Hospital. The study included a sample size of 3294 patients with selection criteria based on presenting symptoms and COVID-19 status. Data collection occurred from 2019 and 2021, and demographic information (age, gender, weight), medical history (perinatal and family history), COVID-19 status (vaccination, infection history), and details about chest pain (frequency, onset) were documented. Statistical analyses were performed to evaluate differences between the two time periods using IBM SPSS Statistics for Windows, Version 28 (Released 2021; IBM Corp., Armonk, New York, United States).

RESULTS

The results indicate a significant increase in the number of patients presenting with chest pain in 2021 compared to 2019 (P value = .0157). The mean age of patients was 11 years, predominantly male. There was a notable increase in the percentage of patients with comorbidities in 2021. Echocardiography results were normal in approximately 84% of cases across both years, with no significant differences in ECG outcomes. Palpitations remained the most common associated symptom. 4.6 % of patients in 2021 were confirmed to have COVID-19, most of whom were diagnosed with muscular causes of chest pain. Notably, none of the patients had received the COVID-19 vaccine.

CONCLUSIONS

This study highlights a marked increase in pediatric patients presenting with chest pain during the pandemic, although characteristics and underlying causes remained consistent between years. The rise in cases may be attributed to heightened awareness rather than a direct link to COVID-19. Recommendations for clinical practice include careful evaluation of chest pain in pediatric patients during the pandemic, considering psychosocial factors and the broader impact of COVID-19 on health-seeking behaviors. Future research should investigate the long-term effects of COVID-19 on pediatric populations and explore the psychological implications on health service utilization. This study underscores the need for ongoing assessment of pediatric healthcare practices amid evolving pandemic conditions.

Emergency department presentations for chest complaints after mRNA COVID-19 vaccinations in children and adolescents

OBJECTIVE

To investigate characteristics and management of children presenting with chest complaints to a tertiary paediatric ED post-mRNA COVID-19 vaccine.

METHODS

This was a retrospective medical record review with data linkage to the Australian Immunisation Register. The study setting was the Royal Children's Hospital, Melbourne, Australia. Children <18 years who had a troponin blood test performed in hospital within 14 days of receiving mRNA COVID-19 vaccination were included. Elevated troponin and myocarditis or pericarditis as per Brighton criteria was the primary outcome. Vaccination status, length of stay, investigations and clinical management were secondary outcomes.

RESULTS

Six hundred and ten patients had a troponin test in 13 months. After exclusion of trauma-related tests (n = 31), known cardiac patients (n = 75) and others (n = 145), 359 troponins were obtained due to chest complaints and related symptoms, with 283 troponins assessed to be mRNA vaccination-related. There was a temporal peak in presentations with a 30-fold monthly increase in troponin post-commencement of mRNA COVID-19 vaccines. In those with chest complaints following mRNA vaccination, mean age was 14 years and 50.4% were female. Fourteen out of 283 (5%) vaccine-related troponins were abnormal with 14 patients assessed to have vaccine-associated myocarditis. No patients had pericarditis.

CONCLUSIONS

There was a large number of possible mRNA COVID-19 vaccine-related chest complaints presenting to the ED. Few patients had abnormal troponins or myocarditis.

Chest pain attendances to a Paediatric Emergency Department pre- and post-COVID-19 vaccination

Background

Introduction of the mRNA vaccination for coronavirus disease 2019 (COVID-19) has been associated with an increase in cases of peri/myocarditis. In our retrospective cross-sectional study, we aim to (I) describe paediatric chest pain attendance, and (II) study resource utilisation in the Emergency Department (ED) of KK Women's and Children's Hospital (KKH), stratified by pre-pandemic, during the pandemic pre- and post-COVID vaccination introduction in adolescents.

Methods

We reviewed records of adolescents aged 12 to 18 years old who presented to our ED with the triage complaint of chest pain between 1 January 2019 to 31 January 2022, and determined the attendance rates, aetiologies and resource utilisation during the above time periods.

Results

There were 2,418 ED attendances for chest pain in our study population. Among 887 inpatient admissions for chest pain, 1.8% were attributed to a cardiac cause. Comparing the pre-pandemic period to the period after the mRNA COVID-19 vaccination was introduced, ED chest pain rates increased from a median of 0.5% of ED attendances [interquartile range (IQR), 0.3-0.5%] to 0.9% (IQR, 0.7-2.0%) (P<0.001), while admission rates increased from a median of 26.2% of ED attendances (IQR, 24.1-29.1%) to 40.9% (IQR, 37.6-56.6%) (P<0.001). Cardiac enzyme orders among ED visits for chest pain increased from a pre-pandemic median of 0% (IQR, 0.0-2.6%) to a post-vaccination median of 26.1% (IQR, 17.2-56.2%) (P<0.001) and were due to concerns for vaccine-related myocarditis. Seven cases of probable vaccine-related myocarditis presented with chest pain to our ED.

Conclusions

Paediatric chest pain is largely non-cardiac in origin. ED chest pain attendance rates and resource utilisation increased after the introduction of mRNA COVID-19 vaccination in adolescents.
