Family presence in Canadian PICUs during the COVID-19 pandemic: a mixed-methods environmental scan of policy and practice.

BACKGROUND: Despite their broad commitment to family-centred care, children's hospitals and associated pediatric intensive care units (PICUs) restricted family presence during the COVID-19 pandemic. This study aimed to describe family presence policies and practices in Canadian PICUs from March to May 2020, and their evolution by August to December 2020. METHODS: We conducted an environmental scan of family presence policies and restrictions in all 19 Canadian PICUs using 2 methods. We conducted a literature review of public-facing visitation policy documents in June 2020 using a standardized data extraction form. We also administered a cross-sectional survey of PICU leadership (managers and physician chiefs) between August and December 2020 by telephone or videoconferencing. We used inductive content analysis to code qualitative data, generating summative count data. We analyzed quantitative data descriptively. RESULTS: As part of the literature search, we collected 2 (12%) PICU-specific, 14 (82%) pediatric-specific and 1 (6%) hospital-wide visitation policy documents from the early pandemic. One policy document provided guidance on all of the policy elements sought; the number of enabled caregivers was not included in the documents for 7 of 19 units (37%). All 19 Canadian PICUs were represented among the 24 survey respondents (15 physician chiefs and 9 operations or clinical managers). Before the COVID-19 pandemic, all units allowed the presence of 2 or more family members. Early in the pandemic, reported practices limited the number of adult caregivers for patients without SARS-CoV-2 infection to 1 (n = 21/24, 88%) or 2 (n = 3/24, 12%); all units prohibited siblings. Some centres restricted caregivers from switching bedside presence with one another (patients without SARS-CoV-2 infection: n = 16/23, 70%; patients with confirmed or suspected SARS-CoV-2 infection: n = 20/23, 87%); leaving their child's PICU room (patients without SARS-CoV-2 infection: n = 1/24, 4%; patients with confirmed or suspected SARS-CoV-2 infection: n = 16/24, 67%); and joining in-person rounds (patients without SARS-CoV-2 infection: n = 9/22, 41%; patients with confirmed or suspected SARS-CoV-2 infection: n = 17/22, 77%). All respondents endorsed policy exceptions during end-of-life care. Some reported policies and practices were adapted over the study period. INTERPRETATION: Early COVID-19-related family presence policies in Canadian PICUs varied among centres. Although some centres adapted policies and practices, this study revealed ongoing potential threats to family centred care at the mid-pandemic stage.

Presumed Systemic Inflammatory Response Syndrome in the Pediatric Emergency Department.

OBJECTIVE: The aim of this study was to examine the incidence and outcomes of patients presenting with systemic inflammatory response syndrome (SIRS) in the pediatric emergency department (PED). METHODS: This was a descriptive, retrospective cohort study of all patients from birth to 18 years presenting to the PED of a single center on 16 days distributed over 1 year. The presence of presumed SIRS (pSIRS, defined as noncore temperature measurement and cell count when clinically indicated) and sepsis was determined for all study patients. Patients were followed up for 1 week. RESULTS: The incidence of pSIRS was 15.3% (216/1416). Suspected or proven infection was present in 37.1% (n = 525) of the study population and 76.4% (n = 165) with pSIRS, with no cases of severe sepsis or septic shock. Sensitivity and specificity of pSIRS for predicting infection were 31.4% (95% confidence interval [CI], 27.5%-35.6%) and 94.3% (95% CI, 92.5%-95.7%), respectively. Although patients with pSIRS had a relative risk of 2.4 (95% CI, 1.6-3.5; P < 0.0001) for admission, 74% were discharged home with no subsequent PED visits. Of defined sepsis cases, 75% were discharged home without return. CONCLUSIONS: Presumed SIRS and sepsis are relatively common in the PED. Use of pSIRS to screen for sepsis risks missing infection, whereas using pSIRS in the current sepsis definition results in overinclusion of nonsevere illness.

Recurrent invasive group A streptococcal infection with four-limb amputation in an immunocompetent child.

We report a previously well paediatric patient with two distinct presentations of invasive group A streptococcus (GAS) infection resulting in significant morbidity. The first episode, following GAS pharyngitis, involved multiorgan dysfunction syndrome. This included cardiorespiratory and acute hepatorenal failure and purpura fulminans that eventually necessitated four-limb amputation. The second episode occurred 12 months later, from undetermined aetiology, and resulted in septic shock. Molecular analysis of the emm gene and PCR for Serum Opacity Factor revealed that the initial isolate was M Type 4 and sof gene positive while the second isolate was M Type 1 and sof gene negative. Immunological investigations, including CH50, quantitative IgA, IgM and IgG, and flow cytometry measuring lymphocyte subsets, and vaccine response to measles, mumps, rubella and pneumococcus were normal. This is the first report of recurrent bacteraemia from different strains of Streptococcus pyogenes infection in an apparently immunocompetent child.

Non-pathological bilious vomiting complicating therapeutic hypothermia for hypoxic ischaemic encephalopathy in neonates: a retrospective cohort study.

OBJECTIVE: Therapeutic hypothermia (TH) for moderate-to-severe neonatal hypoxic ischaemic encephalopathy (HIE) is generally described as safe. We performed this study to determine the incidence of bilious vomiting or bilious drainage (BVD) attributable to TH in this population. DESIGN: A single-centre, retrospective cohort study. SETTING: Neonatal and paediatric intensive care units (NICU and PICU) of a single tertiary care centre. PATIENTS: All newborns with HIE who met criteria for TH between 2009 and 2014. INTERVENTIONS: Cases were matched 1:1 for unit of care (NICU vs PICU), gestational age, gender, and Sarnat score with historic controls who did not receive TH. Groups were compared with Pearson's Χ2 analysis. Relative risk was calculated, and ORs were used to allow regression analysis. RESULTS: Forty-seven patients met all inclusion criteria. The incidence of BVD in patients who received TH was 26%. The group exposed to TH was more likely to experience BVD compared with the control group with a relative risk of 6.0(95% CI 1.4 to 25.4), even after accounting for improper or unchecked nasogastric position, opioids and muscle relaxant use, OR=7.8(95% CI 1.4 to 43.3), and when positive blood culture was included in the regression model, OR=11.6(95% CI 1.2 to 115.0). Three patients underwent investigation and no patients had surgical pathology. CONCLUSION: TH appears to be associated with non-pathological bilious vomiting or gastric drainage. Further prospective data are needed to identify the patients in whom investigation and intervention may be avoided.

Melatonin in Critically Ill Children.

Melatonin, while best known for its chronobiologic functions, has multiple effects that may be relevant in critical illness. It has been used for circadian rhythm maintenance, analgesia, and sedation, and has antihypertensive, anti-inflammatory, antioxidant, antiapoptotic, and antiexcitatory effects. This review examines melatonin physiology in health, the current state of knowledge regarding endogenous melatonin production in pediatric critical illness, and the potential uses of exogenous melatonin in this population, including relevant information from basic sciences and other fields of medicine. Pineal melatonin production and secretion appears to be altered in critical illness, though understanding in pediatric critical illness is in early stages, with only 102 children reported in the current literature. Exogenous melatonin may be used for circadian rhythm disturbances and, within the critically ill population, holds promise for diseases involving oxidant stress. There are no studies of exogenous melatonin administration to critically ill children beyond the neonatal period.

Diabetic ketoacidosis-associated stroke in children and youth.

Diabetic ketoacidosis (DKA) is a state of severe insulin deficiency, either absolute or relative, resulting in hyperglycemia and ketonemia. Although possibly underappreciated, up to 10% of cases of intracerebral complications associated with an episode of DKA, and/or its treatment, in children and youth are due to hemorrhage or ischemic brain infarction. Systemic inflammation is present in DKA, with resultant vascular endothelial perturbation that may result in coagulopathy and increased hemorrhagic risk. Thrombotic risk during DKA is elevated by abnormalities in coagulation factors, platelet activation, blood volume and flow, and vascular reactivity. DKA-associated cerebral edema may also predispose to ischemic injury and hemorrhage, though cases of stroke without concomitant cerebral edema have been identified. We review the current literature regarding the pathogenesis of stroke during an episode of DKA in children and youth.
