Objectives: To describe the severity and clinical spectrum of coronavirus disease 2019 (COVID‐19) in children during the 2021 New South Wales outbreak of the Delta variant of the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Design, setting: Prospective cohort study in three metropolitan Sydney local health districts, 1 June – 31 October 2021. Participants: Children under 16 years of age with positive SARS‐CoV‐2 nucleic acid test results admitted to hospital or managed by the Sydney Children’s Hospital Network (SCHN) virtual care team. Main outcome measures: Age‐specific SARS‐CoV‐2 infection frequency, overall and separately for SCHN virtual and hospital patients; rates of medical and social reason admissions, intensive care admissions, and paediatric inflammatory multisystem syndrome temporally associated with SARS‐CoV‐2 per 100 SARS‐CoV‐2 infections; demographic and clinical factors that influenced likelihood of hospital admission. Results: A total of 17 474 SARS‐CoV‐2 infections in children under 16 were recorded in NSW, of whom 11 985 (68.6%) received SCHN‐coordinated care, including 459 admitted to SCHN hospitals: 165 for medical reasons (1.38 [95% CI, 1.17–1.59] per 100 infections), including 15 admitted to intensive care, and 294 (under 18 years of age) for social reasons (2.45 [95% CI, 2.18–2.73] per 100 infections). In an analysis that included all children admitted to hospital and a random sample of those managed by the virtual team, having another medical condition (adjusted odds ratio [aOR], 7.42; 95% CI, 3.08–19.3) was associated with increased likelihood of medical admission; in univariate analyses, non‐asthmatic chronic respiratory disease was associated with greater (OR, 9.21; 95% CI, 1.61–174) and asthma/viral induced wheeze with lower likelihood of admission (OR, 0.38; 95% CI, 0.18–0.78). The likelihood of admission for medical reasons declined from infancy to 5–11 years, but rose again for those aged 12–15 years. Sex and Indigenous status did not influence the likelihood of admission. Conclusion: Most SARS‐CoV‐2 infections (Delta variant) in children were asymptomatic or associated with mild disease. Hospitalisation was relatively infrequent, and most common for infants, adolescents, and children with other medical conditions. More children were hospitalised for social than for medical reasons.

Objective(s): To describe the severity and clinical spectrum of SARS-CoV-2 infection in Australian children during the 2021 Delta outbreak. Design, Setting & Participants: A prospective cohort study of children <16 years with a positive SARS-CoV-2 nucleic acid test cared for by the Sydney Children's Hospital Network (SCHN) virtual and inpatient medical teams between 1 June-31 October 2021. Main outcome measures: Demographic and clinical data from all admitted patients and a random sample of outpatients managed under the SCHN virtual care team were analysed to identify risk factors for admission to hospital. Results: There were 17,474 SARS-CoV-2 infections in children <16 years in NSW during the study period, of whom 11,985 (68.6%) received care coordinated by SCHN. Twenty one percent of children infected with SARS-CoV-2 were asymptomatic. For every 100 SARS-CoV-2 infections in children <16 years, 1.26 (95% CI 1.06 to 1.46) required hospital admission for medical care; while 2.46 (95% CI 2.18 to 2.73) required admission for social reasons only. Risk factors for hospitalisation for medical care included age <6 months, a history of prematurity, age 12 to <16 years, and a history of medical comorbidities (aOR 7.23 [95% CI 2.92 to 19.4]). Of 17,474 infections, 15 children (median age 12.8years) required ICU admission; and 294 children required hospital admission due to social or welfare reasons. Conclusion: The majority of children with SARS-CoV-2 infection (Delta variant) had asymptomatic or mild disease. Hospitalisation was uncommon and occurred most frequently in young infants and adolescents with comorbidities. More children were hospitalised for social reasons than for medical care.

IntroductionFrequent asthma attacks in children result in unscheduled hospital presentations. Patient centered care coordination can reduce asthma hospital presentations. In 2016, The Sydney Children's Hospitals Network launched the Asthma Follow up Integrated Care Initiative with the aim to reduce pediatric asthma emergency department (ED) presentations by 50% through developing and testing an integrated model of care led by care coordinators (CCs).MethodsThe integrated model of care was developed by a multidisciplinary team at Sydney Children's Hospital Randwick (SCH,R) and implemented in two phases: Phase I and Phase II. Children aged 2–16 years who presented ≥4 times to the ED of the SCH,R in the preceding 12 months were enrolled in Phase I and those who had ≥4 ED presentations and ≥1 hospital admissions with asthma attack were enrolled in Phase II. Phase I included a suite of interventions delivered by CCs including encouraging parents/carers to schedule follow-up visits with GP post-discharge, ensuring parents/carers are provided with standard asthma resource pack, offering referrals to asthma education sessions, sending a letter to the child's GP advising of the child's recent hospital presentation and coordinating asthma education webinar for GPs. In addition, in Phase II CCs sent text messages to parents/carers reminding them to follow-up with the child's GP. We compared the change in ED visits and hospital admissions at baseline (6 months pre-enrolment) and at 6-and 12-months post-enrolment in the program.ResultsDuring December 2016-January 2021, 160 children (99 in Phase I and 61 in Phase II) were enrolled. Compared to baseline at 6- and 12-months post-enrolment, the proportion of children requiring ≥1 asthma ED presentations reduced by 43 and 61% in Phase I and 41 and 66% in Phase II. Similarly, the proportion of children requiring ≥1 asthma hospital admissions at 6- and 12-months post-enrolment reduced by 40 and 47% in Phase I and 62 and 69% in Phase II.ConclusionOur results support that care coordinator led integrated model of asthma care which enables integration of acute and primary care services and provides families with asthma resources and education can reduce asthma hospital presentations in children.

Introduction:The COVID-19 pandemic has forced a new look (or modernization) for both the obligations and approaches to achieve best-practices in global health learning. These best-practices have moved beyond traditional, face-to-face (F2F), classroom-based didactics to the use of innovative online, asynchronous and synchronous instructional design and the information and communication technology (ICT) tools to support it. But moving to this higher level of online in-service and pre-service training, key obligations (e.g., stopping neocolonialization, cultural humility, reversing brain drain, gender equity) must guide the modernization of instructional design and the supporting ICT. To positively impact global health training, educators must meet the needs of learners where they are.Purpose: We describe a set of multi-communication methods, e-Learning principles, strategies, and ICT approaches for educators to pivot content delivery from traditional, F2F classroom didactics into the modern era. These best-practices in both the obligations and approaches utilize thoughtful, modern strategies of instructional design and ICT. Approach:We harnessed our collective experiences in global health training to present thoughtful insights on the guiding principles, strategies, and ICT environment central to develop learning curricula that meet trainee needs and how they can be actualized. Specifically, we describe five strategies: 1. Individualized learning; 2. Provide experiential learning; 3. Mentor … Mentor … Mentor; 4. Reinforce learning through assessment; and 5. Information and communication technology and tools to support learning. Discussion:We offer a vision, set of guiding principles, and five strategies for successful curricula delivery in the modern era so that global health training can be made available to a wider audience more efficiently and effectively.
