Paediatric inflammatory multisystem syndrome in Canada: population-based surveillance and role of SARS-CoV-2 linkage.

BACKGROUND: Paediatric inflammatory multisystem syndrome (PIMS) is a rare condition temporally associated with SARS-CoV-2 infection. Using national surveillance data, we compare presenting features and outcomes among children hospitalized with PIMS by SARS-CoV-2 linkage, and identify risk factors for intensive care (ICU). METHODS: Cases were reported to the Canadian Paediatric Surveillance Program by a network of >2800 pediatricians between March 2020 and May 2021. Patients with positive versus negative SARS-CoV-2 linkages were compared, with positive linkage defined as any positive molecular or serologic test or close contact with confirmed COVID-19. ICU risk factors were identified with multivariable modified Poisson regression. RESULTS: We identified 406 children hospitalized with PIMS, including 49.8% with positive SARS-CoV-2 linkages, 26.1% with negative linkages, and 24.1% with unknown linkages. The median age was 5.4 years (IQR 2.5-9.8), 60% were male, and 83% had no comorbidities. Compared to cases with negative linkages, children with positive linkages experienced more cardiac involvement (58.8% vs. 37.4%; p < 0.001), gastrointestinal symptoms (88.6% vs. 63.2%; p < 0.001), and shock (60.9% vs. 16.0%; p < 0.001). Children aged ≥6 years and those with positive linkages were more likely to require ICU. CONCLUSIONS: Although rare, 30% of PIMS hospitalizations required ICU or respiratory/hemodynamic support, particularly those with positive SARS-CoV-2 linkages. IMPACT: We describe 406 children hospitalized with paediatric inflammatory multisystem syndrome (PIMS) using nationwide surveillance data, the largest study of PIMS in Canada to date. Our surveillance case definition of PIMS did not require a history of SARS-CoV-2 exposure, and we therefore describe associations of SARS-CoV-2 linkages on clinical features and outcomes of children with PIMS. Children with positive SARS-CoV-2 linkages were older, had more gastrointestinal and cardiac involvement, and hyperinflammatory laboratory picture. Although PIMS is rare, one-third required admission to intensive care, with the greatest risk amongst those aged ≥6 years and those with a SARS-CoV-2 linkage.

"We survived the pandemic together”: The impact of the COVID-19 pandemic on Canadian families living with chronic pain

Introduction Pediatric chronic pain is a significant problem in Canada, affecting one in five youth. This study describes the impact of the pandemic on the experiences of Canadian families living with chronic pain through interviews with youth living with chronic pain, parents, and siblings. Methods Employing a qualitative descriptive design, in-depth semistructured interviews were completed with Canadian youth living with pain, as well as parents and siblings. Participants were not required to be related. Interviews were analyzed using a reflexive thematic analysis approach. Results Forty-four interviews were completed with 14 parents, 19 youth with chronic pain, and 11 siblings from across the country. Three key themes were developed: (1) absorbing and shifting: the toll of the pandemic on the family system (e.g., loss of coping mechanisms, shifting roles to respond to the pandemic), (2) social ambiguity and abandonment (e.g., social sacrifice and abandonment by the health care system), and (3) building community resilience: familial adaptation to the pandemic (e.g., family cohesion, confidence, and self-management). Discussion/Conclusions Youth, parents, and siblings reported that the pandemic impacted coping strategies across the family system. These results outline the challenges youth experienced managing their pain and overall health throughout the pandemic and the resilience built within families during this time. Going forward, it would be relevant to examine how racialized and structurally marginalized youth with chronic pain and their families experienced the pandemic. Future research should examine how unexpected benefits of the pandemic (e.g., increased confidence and self-management) may be sustained into the future.

Introduction: La douleur chronique pédiatrique est un problème important au Canada, qui touche un jeune sur cinq. Cette étude décrit les répercussions de la pandémie sur les expériences des familles canadiennes vivant avec la douleur chronique par des entrevues avec des jeunes vivant avec une douleur chronique, des parents et des frères et sœurs.Méthodes: À l'aide d'un devis descriptif qualitatif, des entretiens semi-structurés approfondis ont été réalisés auprès de jeunes Canadiens vivant avec la douleur, leurs parents, et leurs frères et sœurs. Il n'était pas nécessaire que les participants aient un lien familial. Les entretiens ont été analysés à l'aide d'une approche d'analyse thématique réflexive.Résultats: Quarante-quatre entretiens ont été réalisés auprès de 14 parents, 19 jeunes souffrant de douleur chronique et 11 frères et sœurs de tout le pays. Trois thèmes clés ont été abordés : (1) l'absorption et le changement : le coût de la pandémie pour le système familial (p. ex., perte de mécanismes d'adaptation, changement de rôles pour réagir à la pandémie), (2) l'ambiguïté sociale et l'abandon (p. ex., le sacrifice social et l'abandon par le système de soins de santé), et (3) le renforcement de la résilience communautaire : adaptation familiale à la pandémie (p. ex., cohésion familiale, confiance et auto-prise en charge).Discussion/Conclusions: Les jeunes, les parents et les frères et sœurs ont signalé que la pandémie avait eu des répercussions sur les stratégies d'adaptation dans l'ensemble du système familial. Ces résultats décrivent les défis rencontrés par les jeunes pour prendre en charge leur douleur et leur santé globale tout au long de la pandémie, ainsi que la résilience démontrée par les familles pendant cette période. À l'avenir, il serait pertinent d'examiner comment les personnes racialisées et les jeunes structurellement marginalisés souffrant de douleur chronique et leurs familles ont vécu la pandémie.Les recherches futures devraient examiner comment les avantages inattendus de la pandémie (par exemple, une confiance accrue et l'auto-prise en charge) peuvent être maintenus à l'avenir.

Risk factors for severe COVID-19 in hospitalized children in Canada: A national prospective study from March 2020-May 2021.

Background: Children living with chronic comorbid conditions are at increased risk for severe COVID-19, though there is limited evidence regarding the risks associated with specific conditions and which children may benefit from targeted COVID-19 therapies. The objective of this study was to identify factors associated with severe disease among hospitalized children with COVID-19 in Canada. Methods: We conducted a national prospective study on hospitalized children with microbiologically confirmed SARS-CoV-2 infection via the Canadian Paediatric Surveillance Program (CPSP) from April 2020-May 2021. Cases were reported voluntarily by a network of >2800 paediatricians. Hospitalizations were classified as COVID-19-related, incidental infection, or infection control/social admissions. Severe disease (among COVID-19-related hospitalizations only) was defined as disease requiring intensive care, ventilatory or hemodynamic support, select organ system complications, or death. Risk factors for severe disease were identified using multivariable Poisson regression, adjusting for age, sex, concomitant infections, and timing of hospitalization. Findings: We identified 544 children hospitalized with SARS-CoV-2 infection, including 60·7% with COVID-19-related disease and 39·3% with incidental infection or infection control/social admissions. Among COVID-19-related hospitalizations (n=330), the median age was 1·9 years (IQR 0·1-13·3) and 43·0% had chronic comorbid conditions. Severe disease occurred in 29·7% of COVID-19-related hospitalizations (n=98/330 including 60 admitted to intensive care), most frequently among children aged 2-4 years (48·7%) and 12-17 years (41·3%). Comorbid conditions associated with severe disease included pre-existing technology dependence requirements (adjusted risk ratio [aRR] 2·01, 95% confidence interval [CI] 1·37-2·95), body mass index Z-scores ≥3 (aRR 1·90, 95% CI 1·10-3·28), neurologic conditions (e.g. epilepsy and select chromosomal/genetic conditions) (aRR 1·84, 95% CI 1·32-2·57), and pulmonary conditions (e.g. bronchopulmonary dysplasia and uncontrolled asthma) (aRR 1·63, 95% CI 1·12-2·39). Interpretation: While severe outcomes were detected at all ages and among patients with and without comorbidities, neurologic and pulmonary conditions as well as technology dependence were associated with increased risk of severe COVID-19. These findings may help guide vaccination programs and prioritize targeted COVID-19 therapies for children. Funding: Financial support for the CPSP was received from the Public Health Agency of Canada.

Experiences of Pediatric Pain Professionals Providing Care during the COVID-19 Pandemic: A Qualitative Study.

Chronic pain affects 1 in 5 youth, many of whom manage their pain using a biopsychosocial approach. The COVID-19 pandemic has impacted the way that healthcare is delivered. As part of a larger program of research, this study aimed to understand the impact of the pandemic on pediatric chronic pain care delivery including impact on patients' outcomes, from the perspective of pediatric healthcare providers. A qualitative descriptive study design was used and 21 healthcare providers from various professional roles, clinical settings, and geographic locations across Canada were interviewed. Using a reflexive thematic analysis approach 3 themes were developed: (1) duality of pandemic impact on youth with chronic pain (i.e., how the pandemic influenced self-management while also exacerbating existing socioeconomic inequalities); (2) changes to the healthcare system and clinical practices (i.e., triaging and access to care); (3) shift to virtual care (i.e., role of institutions and hybrid models of care). These findings outline provider perspectives on the positive and negative impacts of the pandemic on youth with chronic pain and highlight the role of socioeconomic status and access to care in relation to chronic pain management during the pandemic in a high-income country with a publicly funded healthcare system.

Caractéristiques des hospitalisations au Canada d'enfants ayant contracté une infection aiguë par le SRAS-CoV-2 en 2020.

CONTEXTE: Les facteurs de risque de complications graves de l'infection par le SRAS-CoV-2 n'ont pas été bien établis chez les enfants. Nous avons voulu décrire les hospitalisations pédiatriques associées au SRAS-CoV-2 au Canada et identifier les facteurs de risque de maladie grave. MÉTHODES: Nous avons procédé à une étude prospective nationale en utilisant l'infrastructure du Programme canadien de surveillance pédiatrique (PCSP). Les hospitalisations d'enfants ayant contracté une infection par le SRAS-CoV-2 confirmée en laboratoire de microbiologie ont été rapportées du 8 avril au 31 décembre 2020 au moyen de questionnaires hebdomadaires en ligne distribués au réseau du PCSP, qui compte plus de 2800 pédiatres. Nous avons catégorisé les hospitalisations comme suit : liées à la COVID-19, infections découvertes fortuitement, ou hospitalisations pour des raisons sociales ou de contrôle des infections, et dégagé les facteurs de risque associés à la gravité de la maladie chez les patients hospitalisés. RÉSULTATS: Sur les 264 hospitalisations d'enfants ayant contracté le SRAS-CoV-2 au cours de la période de l'étude de 9 mois, 150 (56,8 %) ont été associées à la COVID-19 et 100 (37,9 %) étaient des cas découverts fortuitement (admission pour d'autres raisons et découverte fortuite du SRAS-CoV-2 par dépistage positif). Les nourrissons (37,3 %) et les adolescents (29,6 %) représentaient la majorité des cas. Parmi les hospitalisations liées à la COVID-19, 52 patients (34,7 %) étaient atteints d'une forme grave de la maladie, dont 42 (28,0 % des cas liés à la COVID-19) ont eu besoin d'une forme d'assistance respiratoire ou hémodynamique, et 59 (39,3 %) présentaient au moins 1 comorbidité sous-jacente. Les enfants atteints d'obésité, de maladies neurologiques chroniques ou de maladies pulmonaires chroniques, à l'exclusion de l'asthme, étaient plus susceptibles de présenter une forme grave ou critique de la COVID-19. INTERPRÉTATION: Parmi les enfants hospitalisés au Canada chez lesquels on a diagnostiqué une infection par le SRAS-CoV-2 au début de la pandémie de COVID-19, la découverte fortuite du SRAS-CoV-2 a été fréquente. Chez les enfants hospitalisés pour une COVID-19 aiguë, l'obésité et les comorbidités neurologiques et respiratoires ont été associées à une gravité accrue.

Characteristics of children admitted to hospital with acute SARS-CoV-2 infection in Canada in 2020.

BACKGROUND: Risk factors for severe outcomes of SARS-CoV-2 infection are not well established in children. We sought to describe pediatric hospital admissions associated with SARS-CoV-2 infection in Canada and identify risk factors for more severe disease. METHODS: We conducted a national prospective study using the infrastructure of the Canadian Paediatric Surveillance Program (CPSP). Cases involving children who were admitted to hospital with microbiologically confirmed SARS-CoV-2 infection were reported from Apr. 8 to Dec. 31 2020, through weekly online questionnaires distributed to the CPSP network of more than 2800 pediatricians. We categorized hospital admissions as related to COVID-19, incidental, or for social or infection control reasons and determined risk factors for disease severity in hospital. RESULTS: Among 264 hospital admissions involving children with SARS-CoV-2 infection during the 9-month study period, 150 (56.8%) admissions were related to COVID-19 and 100 (37.9%) were incidental infections (admissions for other reasons and found to be positive for SARS-CoV-2 on screening). Infants (37.3%) and adolescents (29.6%) represented most cases. Among hospital admissions related to COVID-19, 52 (34.7%) had critical disease, 42 (28.0%) of whom required any form of respiratory or hemodynamic support, and 59 (39.3%) had at least 1 underlying comorbidity. Children with obesity, chronic neurologic conditions or chronic lung disease other than asthma were more likely to have severe or critical COVID-19. INTERPRETATION: Among children who were admitted to hospital with SARS-CoV-2 infection in Canada during the early COVID-19 pandemic period, incidental SARS-CoV-2 infection was common. In children admitted with acute COVID-19, obesity and neurologic and respiratory comorbidities were associated with more severe disease.

Accessing care in multidisciplinary pain treatment facilities continues to be a challenge in Canada.

BACKGROUND: Multidisciplinary pain treatment facilities (MPTFs) are considered the optimal settings for the management of chronic pain (CP). This study aimed (1) to determine the distribution of MPTFs across Canada, (2) to document time to access and types of services, and (3) to compare the results to those obtained in 2005-2006. METHODS: This cross-sectional study used the same MPTF definition as in 2005-2006-that is, a clinic staffed with professionals from a minimum of three different disciplines (including at least one medical specialty) and whose services were integrated within the facility. A comprehensive search strategy was used to identify existing MPTFs across Canada. Administrative leads at each MPTF were invited to complete an online questionnaire regarding their facilities. RESULTS: Questionnaires were completed by 104 MPTFs (response rate 79.4%). Few changes were observed in the distribution of MPTFs across Canada compared with 12 years ago. Most (91.3%) are concentrated in large urban cities. Prince Edward Island and the Territories still lack MPTFs. The number of pediatric-only MPTFs has nearly doubled but remains small (n=9). The median wait time for a first appointment in publicly funded MPTFs is about the same as 12 years ago (5.5 vs 6 months). Small but positive changes were also observed. CONCLUSION: Accessibility to public MPTFs continues to be limited in Canada, resulting in lengthy wait times for a first appointment. Community-based MPTFs and virtual care initiatives to distribute pain services into regional and remote communities are needed to provide patients with CP with optimal care.
