Effect of the COVID-19 Pandemic on Patient Volumes, Acuity, and Outcomes in Pediatric Emergency Departments: A Nationwide Study

Objectives The aim of this study was to quantify the effect of the COVID-19 pandemic on pediatric emergency department (ED) utilization and outcomes. Methods This study is an interrupted-Time-series observational study of children presenting to 11 Canadian tertiary-care pediatric EDs. Data were grouped into weeks in 3 study periods: prepandemic (January 1, 2018-January 27, 2020), peripandemic (January 28, 2020-March 10, 2020), and early pandemic (March 11, 2020-April 30, 2020). These periods were compared with the same time intervals in the 2 preceding calendar years. Primary outcomes were number of ED visits per week. The secondary outcomes were triage acuity, hospitalization, intensive care unit (ICU) admission, mortality, length of hospital stay, ED revisits, and visits for trauma and mental health concerns. Results There were 577,807 ED visits (median age, 4.5 years; 52.9% male). Relative to the prepandemic period, there was a reduction [-58%; 95% confidence interval (CI),-63% to-51%] in the number of ED visits during the early-pandemic period, with concomitant higher acuity. There was a concurrent increase in the proportion of ward [odds ratio (OR), 1.39; 95% CI, 1.32-1.45] and intensive care unit (OR, 1.20; 95% CI, 1.01-1.42) admissions, and trauma-related ED visits among children less than 10 years (OR, 1.51; 95% CI, 1.45-1.56). Mental health-related visits in children declined in the early-pandemic period (in \u3c10 years,-60%; 95% CI,-67% to-51%; in children ≥10 years:-56%; 95% CI,-63% to-47%) relative to the pre-COVID-19 period. There were no differences in mortality or length of stay; however, ED revisits within 72 hours were reduced during the early-pandemic period (percent change:-55%; 95% CI,-61% to-49%; P \u3c 0.001). Conclusions After the declaration of the COVID-19 pandemic, dramatic reductions in pediatric ED visits occurred across Canada. Children seeking ED care were sicker, and there was an increase in trauma-related visits among children more than 10 years of age, whereas mental health visits declined during the early-pandemic period. When faced with a future pandemic, public health officials must consider the impact of the illness and the measures implemented on children\u27s health and acute care needs

Health-Related Quality of Life and Fatigue in Children and Adults with Pyruvate Kinase Deficiency

Pyruvate kinase deficiency (PKD) is the most common cause of congenital nonspherocytic hemolytic anemia. Although recognition of the disease spectrum has recently expanded, data describing its impact on health-related quality of life (HRQoL) are limited. In this prospective international cohort of 254 patients (131 adults and 123 children) with PKD, we used validated measures to assess the impact of disease on HRQoL (EuroQol 5-Dimension Questionnaire, Pediatric Quality of Life Inventory Generic Core Scale version 4.0, and Functional Assessment of Cancer Therapy-Anemia) and fatigue (Patient Reported Outcomes Measurement Information System Fatigue and Pediatric Functional Assessment of Chronic Illness Therapy-Fatigue). Significant variability in HRQoL and fatigue was reported for adults and children, although individual scores were stable over a 2-year interval. Although adults who were regularly transfused reported worse HRQoL and fatigue compared with those who were not (EuroQol-visual analog scale, 58 vs 80; P = .01), this difference was not seen in children. Regularly transfused adults reported lower physical, emotional, and functional well-being and more anemia symptoms. HRQoL and fatigue significantly differed in children by genotype, with the worst scores in those with 2 severe PKLR mutations; this difference was not seen in adults. However, iron chelation was associated with significantly worse HRQoL scores in children and adults. Pulmonary hypertension was also associated with significantly worse HRQoL. Additionally, 59% of adults and 35% of children reported that their jaundice upset them, identifying this as an important symptom for consideration. Although current treatments for PKD are limited to supportive care, new therapies are in clinical trials. Understanding the impact of PKD on HRQoL is important to assess the utility of these treatments. This trial was registered at www.clinicaltrials.gov as #NCT02053480

The impact of category, cytopathology and cytogenetics on development and progression of clonal and malignant myeloid transformation in inherited bone marrow failure syndromes

Inherited bone marrow failure syndromes are a group of rare, heterogeneous genetic disorders with a risk of clonal and malignant myeloid transformation including clonal marrow cytogenetic abnormalities, myelodysplastic syndrome and acute myeloid leukemia. The clinical characteristics, risk classification, prognostic factors and outcome of clonal and malignant myeloid transformation associated with inherited bone marrow failure syndromes are largely unknown. The aims of this study were to determine the impact of category, cytopathology and cytogenetics, the three components of the “Category Cytology Cytogenetics” classification of pediatric myelodysplastic syndrome, on the outcome of clonal and malignant myeloid transformation associated with inherited bone marrow failure. We used data from the Canadian Inherited Marrow Failure Registry. Among 327 patients with inherited bone marrow failure syndrome enrolled in the registry, the estimated risk of clonal and malignant myeloid transformation by the age of 18 years was 37%. The risk of clonal and malignant myeloid transformation varied according to the type of inherited bone marrow failure syndrome but was highest in Fanconi anemia. The development of clonal and malignant myeloid transformation significantly affected overall survival. Mortality varied based on cytopathological group. The largest group of patients had refractory cytopenia. Clonal marrow cytogenetic abnormalities were identified in 87% of patients with clonal and malignant myeloid transformation, and different cytogenetic groups had different impacts on disease progression. We conclude that category, cytopathology and cytogenetics in cases of clonal and malignant myeloid transformation associated with inherited bone marrow failure syndromes have an important impact on outcome and that the classification of such cases should incorporate these factors

Transition from paediatric to adult ophthalmology services: what matters most to young people with visual impairment

Purpose: To identify the views and experiences and thus the transition-related needs of young people with visual impairment (VI), so as to inform future practice and policies. Patients and methods: Qualitative study of 17 young people aged 16–19 years (ie the conventional transition age threshold) with VI (best-corrected acuity logMAR worse than 0.48) and without additional impairments, drawn from a sampling frame of paediatric ophthalmology patients attending Great Ormond Street Hospital and Moorfields Eye Hospital (London, UK). In-depth, semistructured interviews were conducted to elicit their experiences, preferences, and attitudes towards transitioning within health care. Qualitative thematic analysis identified themes related to participants’ experience of transition. Results: Eight of 17 participants had transitioned out of paediatric ophthalmology services, 7 had not, and 2 were unsure. Their views and experiences varied. Only 2 of those who had transitioned preferred their prior paediatric service, and 1 still in a paediatric services did not want to transition. Age-appropriate communication and physical clinical environment were two key components of care, both associated with greater confidence to self-manage health care in the future as an adult. Emotional attachment to paediatric services/teams was associated with reluctance to transition. Conclusions: Generic guidance on transition is broadly applicable to children/young people with VI. Age-appropriate communication and appropriate physical clinical environments may be optimally delivered through adolescent ophthalmology services bridging paediatric and adult provision. Lack of research on transitions in paediatric ophthalmology has thus far restricted intervention studies; our findings serve to aid in developing an evidence base to achieve this

A four-step process for formulating and evaluating legal commitments under the Paris Agreement

This paper describes a four-step process to guide national governments in formulating and explaining greenhouse gas (GHG) emissions reduction targets in their Nationally Determined Contributions (NDCs) under the Paris Agreement. The NDC pledges in aggregate are intended to achieve the Paris Agreement's warming limit goal to hold the increase in the global temperature to well below 2°C and to pursue efforts to limit the temperature increase to 1. 5°C. Nations also agreed in the Paris Agreement that their mitigation pledges would be based on equity and common but differentiated responsibilities and respective capabilities, in the light of different national circumstances. This paper describes the four steps that are required tofulfil these commitments, and to ensure that the NDCs are sufficiently transparent to allow the Paris Agreement's 'stocktake' process and 'transparency mechanism' to achieve their goal of increasing the NDCs' ambition and fairness. The four steps are necessary to implement the legal obligations of the parties under the UNFCCC and the Paris Agreement. Thesefour steps are: (1) Select a global warming limit to be achieved by the GHG emissions reduction target; (2) Identify a global carbon budget consistent with achieving the global warming limit at an acceptable probability; (3) Determine the national fair share of the global carbon budget based upon equity and common but differentiated responsibilities and respective capabilities; and, (4) Specify the annual rate of national GHG emissions reductions on the pathway to net zero emissions.Donald A Brown, Hugh Breakey, Peter Burdon, Brendan Mackey and Prue Taylo
