Influence of epidemics and pandemics on paediatric ED use: a systematic review

Effects of COVID-19-targeted non-pharmaceutical interventions on pediatric emergency department use: a quasi-experimental study interrupted time-series analysis in North Italian hospitals, 2017 to 2022

Background

The use of Non-Pharmaceutical Interventions (NPIs) during the COVID-19 pandemic is debated. Understanding the consequences these measures may have on vulnerable populations including children and adolescents is important.

Methods

This is a multicenter, quasi-experimental before-after study involving 12 hospitals of the North Italian Emilia-Romagna Region, with NPI implementation as the intervention event. The 3 years preceding NPI implementation (in March 2020) constituted the pre-pandemic phase. The subsequent 2 years were further subdivided into a school closure phase (SC) and a subsequent mitigation measures phase (MM) with milder restrictions. Interrupted Time Series (ITS) regression analysis was used to calculate PED Standardized Incidence Rate Ratios (SIRR) on the diagnostic categories exhibiting the greatest frequency and/or variation.

Results

In the 60 months of the study there were 765,215 PED visits. Compared to the pre-pandemic rate, overall PED presentations dropped by 58 and 39% during SC and MM, respectively. "Symptoms, signs and Ill-defined conditions," "Injury and poisoning" and "Diseases of the Respiratory System" accounted for 74% of the reduction. A different pattern was instead seen for "Mental Disorders," which exhibited the smallest decrease during SC, and is the only category which rose already at the end of SC. ITS analysis confirmed the strong decrease during SC (level change, IRR 0.17, 95%CI 0.12-0.27) and a significant increase in MM (slope change, IRR 1.23, 95%CI 1.13-1.33), with the sharpest decline (-94%) and rise (+36%) observed in the "Diseases of the Respiratory System" category. Mental Disorders showed a significant increasing trend of 1% monthly over the whole study period exceeding pre-pandemic levels at the end of MM. Females and adolescents showed higher increasing rates both in SC and MM.

Conclusion

NPIs appear to have influenced PED attendance in different ways according to diagnostic categories, mirroring different mechanisms of action. These effects are beneficial in some cases and harmful in others, and establishing a clear balance between pros and cons is a difficult task for public health decision makers. The role of NPIs on PED use appropriateness deserves investigation. The rise in pediatric mental disorders independent of the pandemic makes interventions addressing these issues urgent.

Decision-making regarding accessing paediatric unscheduled healthcare during the COVID-19 pandemic: a mixed methods rapid review and thematic synthesis

OBJECTIVE

Reductions in paediatric unscheduled healthcare utilisation were seen during the COVID-19 pandemic, with concerns around their impact on children's health. The reasons for these changes are not well described. This review aims to explore the factors reported by parents that influenced their decision-making around accessing paediatric unscheduled healthcare during the COVID-19 pandemic.

DESIGN

Mixed methods rapid review and thematic synthesis based on the Enhancing Transparency of Reporting the Synthesis of Qualitative research framework.

DATA SOURCES

MEDLINE, Embase, Web of Science, PsycEXTRA, PsycINFO, Global Health, Global Index Medicus, Dissertations and Theses Global, Google Scholar and OAISter. Studies published from January 2020 to July 2023 were included.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Qualitative, quantitative and mixed methods studies that assessed the perspectives of parents on decisions to access or delay or avoid accessing paediatric unscheduled healthcare during the COVID-19 pandemic.

DATA EXTRACTION AND SYNTHESIS

Nvivo 14.23.0 was used to code results the of the primary studies and develop themes, following a thematic synthesis approach.

RESULTS

Twelve studies were included, all from high-income settings, mainly in Europe. The studies were conducted across varying times and levels of COVID-19-related restrictions. The principal descriptive themes identified were (i) concerns about COVID-19 infection, (ii) balancing and navigating risks, (iii) perception of healthcare service status and conditions and (iv) perception of information and advice. These were developed into analytic themes to further describe the decision-making process.

CONCLUSIONS

Parents balanced a range of risks, concerns, advice and responsibilities when considering accessing paediatric unscheduled healthcare during the COVID-19 pandemic. External sources of advice and information were important; misconceptions around public health advice may reflect the multitude of information sources and the rapidly changing circumstances of the pandemic. Public health policy and planning should consider parent perspectives when developing measures to ensure equitable access to appropriate paediatric healthcare services.

Helping parents know when to seek help for an acutely ill child: Evidence based co-development of a mobile phone app using complex intervention methodology

BACKGROUND

Acute illness accounts for the majority of episodes of illness in children under five years of age and is the age group with the highest consultation rate in general practice in the UK. The number of children presenting to emergency care is also steadily increasing, having risen beyond pre-pandemic numbers. Such high, and increasing, rates of consultation have prompted concerns about parents' level of knowledge and confidence in caring for their children when they are ill, and particularly when and how to seek help appropriately.

AIM

The ASK SNIFF collaboration research programme identified parents' need for accurate and accessible information to help them know when to seek help for a sick child in 2010. This paper presents the resulting programme of research which aimed to co-develop an evidence-based safety netting intervention (mobile app) to help parents know when to seek help for an acutely ill child under the age of five years in the UK.

METHODS

Our programme used a collaborative six step process with 147 parent and 324 health professional participants over a period of six years including: scoping existing interventions, systematic review, qualitative research, video capture, content identification and development, consensus methodology, parent and expert clinical review.

RESULTS

Our programme has produced evidence-based content for an app supported by video clips. Our collaborative approach has supported every stage of our work, ensuring that the end result reflects the experiences, perspectives and expressed needs of parents and the clinicians they consult.

CONCLUSION

We have not found any other resource which has used this type of approach, which may explain why there is no published evaluation data demonstrating the impact of existing UK resources. Future mobile apps should be designed and developed with the service users for whom they are intended.

Epidemiological and clinical evolution of multisystem inflammatory syndrome in children throughout the SARS-CoV-2 pandemic in a tertiary Italian children's hospital

Multisystem inflammatory syndrome in children (MIS-C) is a potentially life-threatening disease temporally linked to SARS-CoV-2 whose incidence and clinical presentation may have been altered by the different SARS-CoV-2 variants and by vaccination.

METHODS

We retrospectively collected the data of all MIS-C cases admitted to the Gaslini Children's Hospital, the hub for SARS-CoV-2 related diseases in Liguria region, Italy, from 01 October 2020, to 30 November 2022, evaluating the ratio between MIS-C cases and (1) COVID-19 paediatric cases in our region, (2) emergency department admissions and (3) emergency department febrile patients. We also compared MIS-C incidence in pre- post-vaccination periods.

RESULTS

We observed a significant global decline in the incidence of MIS-Cover the four variant periods and after the starting of vaccination whereas clinical features, therapeutic management and severity did not significantly vary.

CONCLUSIONS

In our setting, we demonstrated a significant decrease of MIS-C incidence according to the predominant variant and including not vaccinated children. Regardless of variant type, the patients showed similar phenotypes and severity throughout the pandemic. SARS-CoV-2 variants as well as immune protection after previous infections and/or vaccination may have interacted by playing different roles and reducing the incidence of MIS-C.

Drivers for low-acuity pediatric emergency department visits in two tertiary hospitals in Switzerland: a cross-sectional, questionnaire-based study

PURPOSE

Low-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.

METHODS

We 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.

RESULTS

We 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.

CONCLUSION

Economic 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.

Increased rates of invasive bacterial disease in late 2022

Invasive bacterial disease is associated with significant morbidity and mortality. In winter 2022, there was an apparent increased rate of invasive bacterial disease compared to preceding years. Cross-site retrospective analysis of the three Children's Health Ireland (CHI) hospitals looking at children admitted between 1st October 2022-31st December 2022 (Q4) with community-acquired invasive bacterial disease, defined as an abscess in a normally sterile site in the head, neck and chest or isolation or PCR detection of Streptococcus pneumoniae, Neisseria meningitidis, Streptococcus pyogenes (Group A streptococcus) or Haemophilus influenzae from a normally sterile site. Case numbers were compared to Q4 in each of 2018-2021. Eighty-two children met the case definition in Q4 2022 vs 97 (Q4 2018-2021). In 2022, 42/82 (51%) were female, median age 3.75 years (1.5-8.25 years). Only 2 (2%) were immunosuppressed and 2 others (2%) had underlying neurodisability. Fifty (61%) were admitted on second or subsequent presentation to a healthcare setting. Fifty-six (68%) had an abscess in a sterile site. Bloodstream infection (positive blood culture or PCR: 24 (29%)) was the most common site of infection, followed by neck 22 (27%) and intracranial 12 (15%). Group A streptococcus (GAS) 27 (33%) was the most common organism isolated. Seven cases (9%) died in 2022 compared to 2 patients (2%) from 2018 to 2021 (p < 0.05). More children had Paediatric Overall Performance Category (POPC) scores > 1 in 2022 than 2018-2021 (p = 0.003).  Conclusion: Invasive bacterial diseases increased in Q4 2022 with higher morbidity and mortality than in the preceding 4 years. Group A streptococcal infection was the most significant organism in 2022. What is known: • Invasive bacterial disease is the leading cause of childhood mortality globally. • There was an increase in cases of invasive Group A streptococcus infections reported in many countries (including Ireland) during the winter of 2022/23. What is new: • Head, neck and chest abscesses increased in Q4 of 2022 compared to the previous 4 years combined. • Invasive bacterial infections in Q4 of 2022 were associated with higher rates of mortality (9%), paediatric intensive care unit (PICU) admission (24%) and requirement for surgical drainage or intervention (67%) than in the preceding years.

Children presenting with diabetes and diabetic ketoacidosis to Emergency Departments during the COVID-19 pandemic in the UK and Ireland: an international retrospective observational study

OBJECTIVES

To describe the incidence of new onset paediatric diabetes mellitus, clinical characteristics and patterns of presentation to emergency departments (ED) during the COVID-19 pandemic, and to assess whether this increase was associated with SARS-CoV-2 infection.

DESIGN

Retrospective medical record review.

SETTING

Forty nine paediatric EDs across the UK and Ireland.

PATIENTS

All children aged 6 months to 16 years presenting to EDs with (1) new onset diabetes or (2) pre-existing diabetes with diabetic ketoacidosis (DKA), during the COVID-19 pandemic (1 March 2020-28 February 2021) and the preceding year (1 March 2019-28 February 2020).

RESULTS

There were increases in new onset diabetes (1015 to 1183, 17%), compared with background incidence of 3%-5% in the UK over the past 5 years. There were increases in children presenting with new onset diabetes in DKA (395 to 566, 43%), severe DKA (141 to 252, 79%) and admissions to intensive care (38 to 72, 89%). Increased severity was reflected in biochemical and physiological parameters and administration of fluid boluses. Time to presentation from symptom onset for children presenting with new onset diabetes and DKA were similar across both years; healthcare seeking delay did not appear to be the sole contributing factor to DKA during the pandemic. Patterns of presentation changed in the pandemic year and seasonal variation was lost. Children with pre-existing diabetes presented with fewer episodes of decompensation.

CONCLUSIONS

There were increases in new onset diabetes in children and a higher risk of DKA in the first COVID pandemic year.

Infection, Dysbiosis and Inflammation Interplay in the COVID Era in Children

For over three years, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in children and adolescents has generated repercussions, especially a few weeks after infection, for symptomatic patients who tested positive, for asymptomatic ones, or even just the contacts of an infected person, and evolved from severe forms such as multisystem inflammatory syndrome in children (MIS-C) to multifarious clinical manifestations in long COVID (LC). Referred to under the umbrella term LC, the onset of persistent and highly heterogeneous symptoms such as fatigue, post-exertion malaise, cognitive dysfunction, and others have a major impact on the child's daily quality of life for months. The first aim of this review was to highlight the circumstances of the pathophysiological changes produced by COVID-19 in children and to better understand the hyperinflammation in COVID-19 and how MIS-C, as a life-threatening condition, could have been avoided in some patients. Another goal was to better identify the interplay between infection, dysbiosis, and inflammation at a molecular and cellular level, to better guide scientists, physicians, and pediatricians to advance new lines of medical action to avoid the post-acute sequelae of SARS-CoV-2 infection. The third objective was to identify symptoms and their connection to molecular pathways to recognize LC more easily. The fourth purpose was to connect the triggering factors of LC with related sequelae following acute SARS-CoV-2 injuries to systems and organs, the persistence of the virus, and some of its components in hidden reservoirs, including the gut and the central nervous system. The reactivation of other latent infectious agents in the host's immune environments, the interaction of this virus with the microbiome, immune hyperactivation, and autoimmunity generated by molecular mimicry between viral agents and host proteins, could initiate a targeted and individualized management. New high-tech solutions, molecules, probiotics, and others should be discovered to innovatively solve the interplay between RNA persistent viruses, microbiota, and our immune system.
