The characteristics of SARS-CoV-2-positive children in Australian hospitals: a PREDICT network study.

OBJECTIVES: To examine the clinical characteristics and short term outcomes for children with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections who presented to Australian hospitals during 2020 and 2021. DESIGN, SETTING: Retrospective case review study in nineteen hospitals of the Paediatric Research in Emergency Departments International Collaborative (PREDICT) network from all Australian states and territories, including seven major paediatric tertiary centres and eight Victorian hospitals. PARTICIPANTS: SARS-CoV-2-positive people under 18 years of age who attended emergency departments or were admitted to hospital during 1 February 2020 - 31 December 2021. MAIN OUTCOME MEASURES: Epidemiological and clinical characteristics, by hospital care type (emergency department [ED] or inpatient care). RESULTS: A total of 1193 SARS-CoV-2-positive children and adolescents (527 girls, 44%) attended the participating hospitals (107 in 2020, 1086 in 2021). Their median age was 3.8 years (interquartile range [IQR], 0.8-11.4 years); 63 were Aboriginal or Torres Strait Islander people (5%). Other medical conditions were recorded for 293 children (25%), including asthma (86, 7%) and premature birth (68, 6%). Medical interventions were not required during 795 of 1181 ED presentations (67%); children were discharged directly home in 764 cases (65%) and admitted to hospital in 282 (24%; sixteen to intensive care units). The 384 admissions to hospital (including 102 direct admissions) of 341 children (25 infants under one month of age) included 23 to intensive care (6%); the median length of stay was three days (IQR, 1-9 days). Medical interventions were not required during 261 admissions (68%); 44 children received respiratory support (11%) and 21 COVID-19-specific treatments, including antiviral and biologic agents (5%). Being under three months of age (v one year to less than six years: odds ratio [OR], 2.6; 95% confidence interval [CI], 1.7-4.0) and pre-existing medical conditions (OR, 2.5; 95% CI, 1.9-3.2) were the major predictors of hospital admission. Two children died, including one without a known pre-existing medical condition. CONCLUSION: During 2020 and 2021, most SARS-CoV-2-positive children and adolescents who presented to participating hospitals could be managed as outpatients. Outcomes were generally good, including for those admitted to hospital.

The characteristics of SARS-CoV-2-positive children who presented to Australian hospitals during 2020: a PREDICT network study.

OBJECTIVES: To examine the epidemiological and clinical characteristics of SARS-CoV-2-positive children in Australia during 2020. DESIGN, SETTING: Multicentre retrospective study in 16 hospitals of the Paediatric Research in Emergency Departments International Collaborative (PREDICT) network; eleven in Victoria, five in four other Australian states. PARTICIPANTS: Children aged 0-17 years who presented to hospital-based COVID-19 testing clinics, hospital wards, or emergency departments during 1 February - 30 September 2020 and who were positive for SARS-CoV-2. MAIN OUTCOME MEASURES: Epidemiological and clinical characteristics of children positive for SARS-CoV-2. RESULTS: A total of 393 SARS-CoV-2-positive children (181 girls, 46%) presented to the participating hospitals (426 presentations, including 131 to emergency departments [31%]), the first on 3 February 2020. Thirty-three children presented more than once (8%), including two who were transferred to participating tertiary centres (0.5%). The median age of the children was 5.3 years (IQR, 1.9-12.0 years; range, 10 days to 17.9 years). Hospital admissions followed 51 of 426 presentations (12%; 44 children), including 17 patients who were managed remotely by hospital in the home. Only 16 of the 426 presentations led to hospital medical interventions (4%). Two children (0.5%) were diagnosed with the paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS). CONCLUSION: The clinical course for most SARS-CoV-2-positive children who presented to Australian hospitals was mild, and did not require medical intervention.

Personal protective equipment in the paediatric emergency department during the COVID-19 pandemic: Estimating requirements based on staff numbers and patient presentations.

OBJECTIVE: To estimate the personal protective equipment (PPE) required in a paediatric ED during the COVID-19 pandemic comparing the use per patient to use per patient zone, based on the NSW Clinical Excellence Commission (CEC) guidelines in place at the time of the study. METHODS: A retrospective case note review of all patients and staff present in the ED of The Children's Hospital at Westmead, Sydney, Australia in the 24 h period of Sunday 5 April 2020. The primary outcome of PPE estimates was generated from identifying the number of patient contacts and aerosol generating procedures (AGPs) performed per patient as well as the number of staff on shift. RESULTS: One hundred patients attended the ED (50% of usual) and all were included in the study. For a low-risk community environment allocating PPE per patient contact required 48 face shields, 382 surgical masks, 48 N95 masks and 430 gowns for the day, increasing to 430 face shields, 331 surgical masks, 430 N95 masks and 761 gowns in a high-risk community environment. Allocating PPE using zoning reduces the requirement to 48 face shields, 192 surgical masks, 48 N95 masks and 204 gowns, increasing to 196 face shields, 96 surgical masks, 196 N95 masks and 292 gowns per day in a high-risk community environment. CONCLUSION: This study has demonstrated the considerable requirement for PPE in a paediatric ED, which varies according to presentation type and the background prevalence of COVID-19 in the community.
