Pediatric Respiratory Syncytial Virus Hospitalizations, 2017-2023.

Importance: Respiratory syncytial virus (RSV) transmission was disrupted worldwide following the COVID-19 pandemic, and further study is required to better understand these changes. Objective: To compare observed and expected RSV hospital and intensive care unit (ICU) admission rates and characteristics of admitted children during the 2021-2022 and 2022-2023 seasons. Design, Setting, and Participants: A population-based cohort study of all children aged younger than 5 years in Ontario, Canada, July 1, 2017, through March 31, 2023, was conducted. Exposures: Individual and neighborhood-level sociodemographic and clinical characteristics were identified from administrative data, including age, palivizumab eligibility, complex medical conditions, rurality, and living in a marginalized neighborhood. Main Outcomes and Measures: The main outcome was RSV-associated hospitalization. Secondary outcomes included ICU admissions, mechanical ventilation, extracorporeal membrane oxygenation, and in-hospital death. Poisson generalized estimating equations were used to model weekly age- and sex-specific hospitalization rates and estimate expected rates in the postpandemic era; adjusted rate ratios (RRs) and 95% CIs are reported. Results: This cohort study included approximately 700 000 children per study year. Compared with prepandemic years (2017-2018, 2018-2019, and 2019-2020), the 2021-2022 RSV season peaked slightly earlier, but overall admission rates were comparable (289.1 vs 281.4-334.6 per 100 000, or approximately 2000 admissions). The 2022-2023 season peaked a month earlier and resulted in more than twice as many hospitalizations (770.0 per 100 000; n = 4977 admissions). The proportion of children admitted to an ICU in 2022-2023 (13.9%) was slightly higher than prepandemic (9.6%-11.4%); however, the population-based rate was triple the prepandemic levels (106.9 vs 27.6-36.6 per 100 000 children in Ontario). With the exception of palivizumab-eligible children, all sociodemographic and health status characteristics were associated with lower-than-expected RSV hospitalization rates in 2021-2022. In contrast, older age of patients was associated with higher-than-expected rates in 2022-2023 (ie, 24-59 months: RR, 1.90; 95% CI, 1.35-2.66). Conclusions and Relevance: There were notable differences in RSV epidemiologic characteristics in Ontario following the COVID-19 pandemic. It is not yet clear whether and how long atypical RSV epidemics may persist. Clinicians and program planners should consider the potential for ongoing impacts to health care capacity and RSV immunization programs.

Parenteral versus enteral fluids for infants hospitalized with bronchiolitis: The PREFER shared decision-making prospective observational study protocol.

INTRODUCTION: Incorporating shared decision-making (SDM) with children and families in hospitals was a top priority identified by patients, caregivers, and clinicians. Bronchiolitis, a common and costly reason for hospitalization in children, is an exemplar condition to study SDM in hospitals. Internationally, clinical practice guidelines differ when recommending intravenous (IV or parenteral) or nasogastric (NG or enteral) fluids for hospitalized infants with bronchiolitis who are unsafe to be fed orally. While evidence indicates that either IV or NG fluids are safe and effective, parent involvement in SDM in selecting IV or NG fluids is unknown. Our aim is to generate knowledge of SDM with parents in choosing between IV or NG fluids and the benefits and harms of these two treatment options for hospitalized children with bronchiolitis. METHOD: This is a multicenter, prospective, observational study, including children aged <12 months admitted to hospital with bronchiolitis requiring supplemental IV or NG fluids. The primary outcome will evaluate the extent of SDM in choosing IV versus NG fluids using the validated CollaboRATE tool. Secondary outcomes include the proportion of parents provided a choice of IV versus NG fluids; parent knowledge of fluid therapy; rate of fluids; length of hospital stay; and complications. DISCUSSION: This study will evaluate the extent of SDM in hospitalized infants with bronchiolitis who require IV or NG fluids and will evaluate both patient-centered and clinical outcomes that are relevant to clinical practice.

Learning to Trust Yourself: Decision-Making Skills Among Parents of Children With Medical Complexity.

CONTEXT: Children with medical complexity have substantial medical needs and their caregivers must make many challenging decisions about their care. Caregivers often become more involved in decisions over time, but it is unclear what skills they develop that facilitate this engagement. OBJECTIVES: To describe the skills that caregivers developed as they gained experience making medical decisions. METHODS: Eligible caregivers had a child who met referral criteria for their centre's Complex Care program for >1 year, were adults responsible for their child's medical decisions, and spoke English or a language with an available interpreter. We followed a semistructured interview guide to ask caregivers to describe and reflect on two challenging medical decisions that they made for their child-one early and one recent. Guided by interpretive description, we identified and refined themes in an iterative process. RESULTS: We conducted 15 interviews with 16 parents (14 [88%] women, two [13%] men) of a child with medical complexity (aged 1-17 years). Parents described 1) becoming more adept at managing decisional information, 2) recognizing the influence of the decision's context, 3) building stronger relationships with providers, and 4) becoming more effective at guiding their child's care as a decision-maker. As parents built these skills, they developed a greater sense of agency and confidence as decision-makers. CONCLUSION: Parents of children with medical complexity change how they approach decision making over time as they acquire relevant skills. These findings can inform the development of interventions to support skill-building among new caregivers.

Association of empiric antibiotic selection and clinical outcomes in hospitalised children with severe orbital infections: a retrospective cohort study.

OBJECTIVE: To determine the association of initial empiric antibiotic regimens with clinical outcomes in hospitalised children with severe orbital infections. DESIGN: Multi-centre observational cohort study using data from 2009 to 2018 clinical records. SETTING: Canadian children's hospitals (7) and community hospitals (3). PATIENTS: Children between 2 months and 18 years hospitalised for >24 hours with severe orbital infections. INTERVENTIONS: Empiric intravenous antibiotic regimen in the first 24 hours of hospitalisation. MAIN OUTCOME MEASURES: Length of hospital stay and surgical intervention using multivariable median regression and multivariate logistic regression, with adjustment for covariates. RESULTS: Of 1421 patients, 60.0% were male and the median age was 5.5 years (IQR 2.4-9.9). Median length of stay was 86.4 hours (IQR 56.9-137.5) and 180 (12.7%) received surgical intervention. Patients receiving broad-spectrum empiric antibiotics had an increased median length of stay, ranging from an additional 13.8 hours (third generation cephalosporin and anaerobic coverage) to 19.5 hours (third generation cephalosporin, staphylococcal and anaerobic coverage). No antibiotic regimen was associated with a change in the odds of surgical intervention. These findings remained unchanged in sensitivity analyses restricted to more severely ill patients. There was a twofold increase in the percentage of patients receiving the broadest empiric antibiotic regimens containing both staphylococcal and anaerobic coverage from 17.8% in 2009 to 40.3% in 2018. CONCLUSIONS: Empiric use of broad-spectrum antibiotics with staphylococci and anaerobic coverage was associated with longer length of stay and similar rates of surgery in children with orbital infections. There is an urgent need for comparative effectiveness studies of various antibiotic regimes.

Sociodemographic Factors and Trends in Bronchiolitis-Related Emergency Department Visit and Hospitalization Rates.

Importance: Bronchiolitis is the most common and most cumulatively expensive condition in pediatric hospital care. Few population-based studies have examined health inequalities in bronchiolitis outcomes over time. Objective: To examine trends in bronchiolitis-related emergency department (ED) visit and hospitalization rates by sociodemographic factors in a universally funded health care system. Design, Setting, and Participants: This repeated cross-sectional cohort study was performed from April 1, 2004, to March 31, 2022, using population-based health administrative data from children younger than 2 years in Ontario, Canada. Main Outcome and Measures: Bronchiolitis ED visit and hospitalization rates per 1000 person-years reported for the equity stratifiers of sex, residence location (rural vs urban), and material resources quintile. Trends in annual rates by equity stratifiers were analyzed using joinpoint regression and estimating the average annual percentage change (AAPC) with 95% CI and the absolute difference in AAPC with 95% CI from April 1, 2004, to March 31, 2020. Results: Of 2 921 573 children included in the study, 1 422 088 (48.7%) were female and 2 619 139 (89.6%) lived in an urban location. Emergency department visit and hospitalization rates were highest for boys, those with rural residence, and those with least material resources. There were no significant between-group absolute differences in the AAPC in ED visits per 1000 person-years by sex (female vs male; 0.22; 95% CI, -0.92 to 1.35; P = .71), residence (rural vs urban; -0.31; 95% CI -1.70 to 1.09; P = .67), or material resources (quintile 5 vs 1; -1.17; 95% CI, -2.57 to 0.22; P = .10). Similarly, there were no significant between-group absolute differences in the AAPC in hospitalizations per 1000 person-years by sex (female vs male; 0.53; 95% CI, -1.11 to 2.17; P = .53), residence (rural vs urban; -0.62; 95% CI, -2.63 to 1.40; P = .55), or material resources (quintile 5 vs 1; -0.93; 95% CI -3.80 to 1.93; P = .52). Conclusions and Relevance: In this population-based cohort study of children in a universally funded health care system, inequalities in bronchiolitis ED visit and hospitalization rates did not improve over time.

Recurrent Intensive Care Episodes and Mortality Among Children With Severe Neurologic Impairment.

Importance: Children requiring care in a pediatric intensive care unit (PICU) are known to have increased risk of subsequent mortality. Children with severe neurologic impairment (SNI)-who carry neurologic or genetic diagnoses with functional impairments and medical complexity-are frequently admitted to PICUs. Although recurrent PICU critical illness episodes (PICU-CIEs) are assumed to indicate a poor prognosis, the association between recurrent PICU-CIEs and mortality in this patient population is poorly understood. Objective: To assess the association between number of recent PICU-CIEs and survival among children with severe neurologic impairment. Design, Setting, and Participants: This population-based retrospective cohort study used health administrative data from April 1, 2002, to March 31, 2020, on 4774 children born between 2002 and 2019 with an SNI diagnosis code in an Ontario, Canada, hospital record before 16 years of age and a first PICU-CIE from 2002 to 2019. Data were analyzed from November 2021 to June 2023. Exposure: Pediatric intensive care unit critical illness episodes (excluding brief postoperative PICU admissions). Main Outcome and Measures: One-year survival conditioned on the number and severity (length of stay >15 days or use of invasive mechanical ventilation) of PICU-CIEs in the preceding year. Results: In Ontario, 4774 children with SNI (mean [SD] age, 2.1 [3.6] months; 2636 [55.2%] <1 year of age; 2613 boys [54.7%]) were discharged alive between 2002 and 2019 after their first PICU-CIE. Ten-year survival after the initial episode was 81% (95% CI, 79%-82%) for children younger than 1 year of age and 84% (95% CI, 82%-86%) for children 1 year of age or older; the age-stratified curves converged by 15 years after the initial episode at 79% survival (95% CI, 78%-81% for children <1 year and 95% CI, 75%-84% for children ≥1 year). Adjusted for age category and demographic factors, the presence of nonneurologic complex chronic conditions (adjusted hazard ratio [AHR], 1.70 [95% CI, 1.43-2.02]) and medical technology assistance (AHR, 2.32 [95% CI, 1.92-2.81]) were associated with increased mortality. Conditional 1-year mortality was less than 20% regardless of number or severity of recent PICU-CIEs. Among children with high-risk PICU-CIEs, 1-year conditional survival decreased from 90% (95% CI, 89%-91%) after the first PICU-CIE to 81% (95% CI, 77%-86%) after the fourth PICU-CIE. Conclusions and Relevance: This cohort study of children with SNI demonstrated a modest dose-dependent association between PICU-CIEs and short-term mortality. These data did not support the conventional wisdom that recurrent PICU admissions are associated with subsequent high mortality risk.

Oxygen Saturation Targets in Infants Hospitalized With Bronchiolitis: A Multicenter Cohort Study.

OBJECTIVES: To examine 2 hospital oxygen saturation target policies and clinical outcomes in infants hospitalized with bronchiolitis. METHODS: This multicenter cohort study used data collected from a randomized clinical trial of infants aged 4 weeks to 24 months, hospitalized with bronchiolitis at children's and community hospitals from 2016 to 2019. We modeled the association between hospital oxygen saturation target policy, either 90% while awake and 88% while asleep (90%/88%) or 90% while awake and asleep (90%/90%), and clinical outcomes. RESULTS: A total of 162 infants were enrolled at 4 hospitals using a 90%/88% oxygen saturation target and 67 infants at 2 hospitals using a 90%/90% target policy. No significant differences between the 90%/88% group and 90%/90% groups were observed for time to discharge (adjusted hazard ratio, 0.83; 95% confidence interval [CI], 0.61-1.14; P = .25), initiation of supplemental oxygen (adjusted odds ratio [aOR], 0.98; 95% CI, 0.47-2.02; P = .95), time to discontinuation of supplemental oxygen (adjusted hazard ratio, 0.75; 95% CI, 0.44-1.27; P = .28), revisits (aOR, 1.38; 95% CI, 0.52-3.71; P = .52), and parent days missed from work (aOR, 2.41; 95% CI, 0.90-6.41; P = .08). Three infants in the 90%/88% group and none in the 90%/90% group were transferred to the ICU. CONCLUSIONS: Among infants hospitalized with bronchiolitis, clinical outcomes were similar between a hospital oxygen saturation target policy of 90% while awake and 88% while asleep compared with 90% while awake and asleep. These findings may inform the design of future trials of oxygen saturation targets in bronchiolitis hospital care.

Malnutrition care in hospitalized pediatric inpatients: comparison of perceptions and experiences across two pediatric academic health sciences centres.

Malnutrition affects up to one in three Canadian children admitted to hospital. Awareness among pediatric healthcare providers (HCPs) of the prevalence and impacts of hospitalized malnutrition is critical for optimal management. The purpose of this study was to determine perceptions of malnutrition among pediatric HCP across two major academic health sciences centres, and to determine how the use of a standardized pediatric nutritional screening tool at one institution affects responses. Between 2020 and 2022, 192 HCPs representing nursing, dietetics, medicine, and other allied health were surveyed across McMaster Children's Hospital and The Hospital for Sick Children. 38% of respondents from both centres perceived rates of malnutrition between approximately one in three patients. Perceptions of the need for nutritional screening, assessment, and management were similar between centres. All respondents identified the need for better communication of hospitalized malnutrition status to community providers at discharge, and resource limitations affecting nutritional management of pediatric inpatients. This study represents the largest and most diverse survey of inpatient pediatric HCPs to date. We demonstrate high rates of baseline knowledge of hospital malnutrition, ongoing resource challenges, and the need for a systematic approach to pediatric nutritional management.

Hemoglobin Threshold for Blood Transfusion in Young Children Hospitalized with Iron Deficiency Anemia.

Current recommendations advise against blood transfusion in hemodynamically stable children with iron deficiency anemia. In an observational study of 125 children aged 6 through 36 months, hospitalized with iron deficiency anemia, we found that hemoglobin level predicted red blood cell transfusion (area under the curve 0.8862). A hemoglobin of 39 g/L had sensitivity 92% and specificity 72% for transfusion.

Severe Respiratory Disease Among Children With and Without Medical Complexity During the COVID-19 Pandemic.

Importance: Severe respiratory disease declined during the COVID-19 pandemic, partially due to decreased circulation of respiratory pathogens. However, the outcomes of children with higher risk have not been described using population-based data. Objective: To compare respiratory-related hospitalizations, intensive care unit (ICU) admissions, and mortality during the pandemic vs prepandemic, among children with medical complexity (CMC) and without medical complexity (non-CMC). Design, Setting, and Participants: This population-based repeated cross-sectional study used Canadian health administrative data of children aged younger than 18 years in community and pediatric hospitals during a pandemic period (April 1, 2020, to February 28, 2022) compared with a 3-year prepandemic period (April 1, 2017, to March 31, 2020). The pandemic period was analyzed separately for year 1 (April 1, 2020, to March 31, 2021) and year 2 (April 1, 2021, to February 28, 2022). Statistical analysis was performed from October 2022 to April 2023. Main Outcomes and Measures: Respiratory-related hospitalizations, ICU admissions, and mortality before and during the pandemic among CMC and non-CMC. Results: A total of 139 078 respiratory hospitalizations (29 461 respiratory hospitalizations for CMC and 109 617 for non-CMC) occurred during the study period. Among CMC, there were fewer respiratory hospitalizations in both 2020 (rate ratio [RR], 0.44 [95% CI, 0.42-0.46]) and 2021 (RR, 0.55 [95% CI, 0.51-0.62]) compared with the prepandemic period. Among non-CMC, there was an even larger relative reduction in respiratory hospitalizations in 2020 (RR, 0.18 [95% CI, 0.17-0.19]) and a similar reduction in 2021 (RR, 0.55 [95% CI, 0.54-0.56]), compared with the prepandemic period. Reductions in ICU admissions for respiratory illness followed a similar pattern for CMC (2020: RR, 0.56 [95% CI, 0.53-0.59]; 2021: RR, 0.66 [95% CI, 0.63-0.70]) and non-CMC (2020: RR, 0.22 [95% CI, 0.20-0.24]; RR, 0.65 [95% CI, 0.61-0.69]). In-hospital mortality for these conditions decreased among CMC in both 2020 (RR, 0.63 [95% CI, 0.51-0.77]) and 2021 (RR, 0.72 [95% CI, 0.59-0.87]). Conclusions and Relevance: This cross-sectional study found a substantial decrease in severe respiratory disease resulting in hospitalizations, ICU admissions, and mortality during the first 2 years of the pandemic compared with the 3 prepandemic years. These findings suggest that future evaluations of the effect of public health interventions aimed at reducing circulating respiratory pathogens during nonpandemic periods of increased respiratory illness may be warranted.

Core outcomes and factors influencing the experience of care for children with severe acute exacerbations of asthma: a qualitative study.

OBJECTIVE: To identify the outcomes considered important, and factors influencing the patient experience, for parents and caregivers of children presenting to hospital with a severe acute exacerbation of asthma. This work contributes to the outcome-identification process in developing a core outcome set (COS) for future clinical trials in children with severe acute asthma. DESIGN: A qualitative study involving semistructured interviews with parents and caregivers of children who presented to hospital with a severe acute exacerbation of asthma. SETTING: Hospitals in 12 countries associated with the global Pediatric Emergency Research Networks, including high-income and middle-income countries. Interviews were conducted face-to-face, by teleconference/video-call, or by phone. FINDINGS: Overall, there were 54 interviews with parents and caregivers; 2 interviews also involved the child. Hospital length of stay, intensive care unit or high-dependency unit (HDU) admission, and treatment costs were highlighted as important outcomes influencing the patient and family experience. Other potential clinical trial outcomes included work of breathing, speed of recovery and side effects. In addition, the patient and family experience was impacted by decision-making leading up to seeking hospital care, transit to hospital, waiting times and the use of intravenous treatment. Satisfaction of care was related to communication with clinicians and frequent reassessment. CONCLUSIONS: This study provides insight into the outcomes that parents and caregivers believe to be the most important to be considered in the process of developing a COS for the treatment of acute severe exacerbations of asthma.

De-implementing low-value continuous pulse oximetry practice in infants hospitalized with bronchiolitis: A multicentre qualitative study.

BACKGROUND: Clinical trial evidence supports the routine use of intermittent pulse oximetry in stabilized infants hospitalized with bronchiolitis. However, continuous pulse oximetry use is common. OBJECTIVE: This study aimed to understand the barriers and facilitators to de-implement continuous pulse oximetry and implement intermittent pulse oximetry in infants hospitalized with stabilized bronchiolitis. METHODS: This multicentre qualitative study interviewed attending pediatricians, residents, nurses, respiratory therapists, and caregivers of infants hospitalized with bronchiolitis at hospitals in Ontario, Canada, to explore beliefs, attitudes, and experiences regarding pulse oximetry use in bronchiolitis management. Data were analyzed using thematic analysis to understand barriers and facilitators to practice change, mapped to the Consolidated Framework for Implementation Research (CFIR) domains. RESULTS: Sixty-seven participants from six hospitals were interviewed using individual interviews and focus groups. Healthcare providers emphasized the importance of identifying and understanding who is responsible for bedside pulse oximetry practice (physicians vs. nurses). Clinical experience, knowledge of guidelines, importance versus competing priorities, and the tensions among team members due to practice variation in monitoring, influenced monitoring practice. Nurses believed in the advantages of intermittent monitoring (reduced alarm fatigue, facilitation of timely discharges, and reduced workload). Clinicians identified ways to clarify indications for continuous monitoring (based on patient risk factors), versus indications to transition to intermittent monitoring (established oral feeding, sleeping without desaturations). Caregivers did not express a clear preference for monitoring type; rather, they described the need for clear communication around interpreting monitor readings, management decisions, and care transitions. CONCLUSIONS: Understanding professional roles, clarity around local practice standards and supporting families' understanding of pulse oximetry practice is essential for practice change. These findings may inform hospital quality improvement efforts to de-implement continuous monitoring in bronchiolitis hospital care.

A Feeding Adequacy Scale for Children With Bronchiolitis: Prospective Multicenter Study.

OBJECTIVES: To determine the measurement properties of the Feeding Adequacy Scale (FAS) in young children hospitalized with bronchiolitis. METHODS: Multicenter cohort study of infants hospitalized with bronchiolitis at children's and community hospitals in Ontario, Canada. Caregivers and nurses completed the FAS, a 10-cm visual analog scale anchored by "not feeding at all" (score 0) and "feeding as when healthy" (score 10). The main outcome measures were feasibility, reliability, validity, and responsiveness of the FAS. RESULTS: A total of 228 children were included with an average (SD) age of 6.3 (5.4) months. Completing the FAS was feasible for caregivers and nurses, with no floor or ceiling effects. Test-retest reliability was moderate for caregivers (intraclass correlation coefficient [ICC] 2,1 0.73; 95% confidence interval [CI] 0.63-0.80) and good for nurses (ICC 2,1 0.75; 95% CI 0.62-0.83). Interrater reliability between 1 caregiver and 1 nurse was moderate (ICC 1,1 0.55; 95% CI 0.45-0.64). For construct validity, the FAS was negatively associated with length of hospital stay and positively associated with both caregiver and nurse readiness for discharge scores (P values <.0001). The FAS demonstrated clinical improvement from the first FAS score at admission to the last FAS score at discharge, with significant differences between scores for both caregivers and nurses (P values for paired t test <.0001). CONCLUSIONS: These results provide evidence of the feasibility, reliability, validity, and responsiveness of caregiver-completed and nurse-completed FAS as a measure of feeding adequacy in children hospitalized with bronchiolitis.

Abscess volume as a predictor of surgical intervention in children hospitalized with orbital cellulitis: A multicentre cohort study.

IMPORTANCE: Orbital cellulitis with subperiosteal or orbital abscess can result in serious morbidity and mortality in children. Objective volume criterion measurement on cross-sectional imaging is a useful clinical tool to identify patients with abscess who may require surgical drainage. OBJECTIVE: To determine the predictive value of abscess volume and the optimal volume cut-point for surgical intervention. DESIGN: We conducted an observational cohort study using medical records from children hospitalized between 2009 and 2018. SETTING: Multicentre study using data from 6 children's hospitals. PARTICIPANTS: Children were included if they were between 2 months and 18 years of age and hospitalized for an orbital infection with an abscess confirmed on cross-sectional imaging. EXPOSURE: Subperiosteal or orbital abscess volume. MAIN OUTCOME AND MEASURES: The primary outcome was surgical intervention, defined as subperiosteal and/or orbital abscess drainage. Multivariable logistic regression was performed to assess the association of abscess volume with surgery. To determine the optimal abscess volume cut-point, receiver operating characteristic (ROC) analysis was performed using the Youden Index to optimize sensitivity and specificity. RESULTS: Of the 150 participants (mean [SD] age, 8.5 [4.5] years), 68 (45.3%) underwent surgical intervention. On multivariable analysis, larger abscess volume and non-medial abscess location were associated with surgical intervention (abscess volume: adjusted odds ratio [aOR], 1.46; 95% CI, 1.11-1.93; abscess location: aOR, 3.46; 95% CI, 1.4-8.58). ROC analysis demonstrated an optimal abscess volume cut-point of 1.18 mL [AUC: 0.75 (95% CI 0.67-0.83) sensitivity: 66%; specificity: 79%]. CONCLUSIONS AND RELEVANCE: In this multicentre cohort study of 150 children with subperiosteal or orbital abscess, larger abscess volume and non-medial abscess location were significant predictors of surgical intervention. Children with abscesses >1.18 mL should be considered for surgery.

Diagnostic test accuracy of ultrasound for orbital cellulitis: A systematic review.

BACKGROUND: Periorbital and orbital cellulitis are inflammatory conditions of the eye that can be difficult to distinguish using clinical examination alone. Computer tomography (CT) scans are often used to differentiate these two infections and to evaluate for complications. Orbital ultrasound (US) could be used as a diagnostic tool to supplement or replace CT scans as the main diagnostic modality. No prior systematic review has evaluated the diagnostic test accuracy (DTA) of ultrasound compared to cross-sectional imaging. OBJECTIVE: To conduct a systematic review of studies evaluating the DTA of orbital ultrasound compared with cross-sectional imaging, to diagnose orbital cellulitis. METHODS: MEDLINE, EMBASE, CENTRAL, and Web of Science were searched from inception to August 10, 2022. All study types were included that enrolled patients of any age with suspected or diagnosed orbital cellulitis who underwent ultrasound and a diagnostic reference standard (i.e., CT or magnetic resonance imaging [MRI]). Two authors screened titles/abstracts for inclusion, extracted data, and assessed the risk of bias. RESULTS: Of the 3548 studies identified, 20 were included: 3 cohort studies and 17 case reports/series. None of the cohort studies directly compared the diagnostic accuracy of ultrasound with CT or MRI, and all had high risk of bias. Among the 46 participants, diagnostic findings were interpretable in 18 (39%) cases which reported 100% accuracy. We were unable to calculate sensitivity and specificity due to limited data. In the descriptive analysis of the case reports, ultrasound was able to diagnose orbital cellulitis in most (n = 21/23) cases. CONCLUSION: Few studies have evaluated the diagnostic accuracy of orbital ultrasound for orbital cellulitis. The limited evidence based on low quality studies suggests that ultrasound may provide helpful diagnostic information to differentiate orbital inflammation. Future research should focus studies to determine the accuracy of orbital US and potentially reduce unnecessary exposure to radiation.

Exploring the lived experience of patients and families who speak language other than English (LOE) for healthcare: developing a qualitative study.

BACKGROUND: Patients who use Languages other than English (LOE) for healthcare communication in an English-dominant region are at increased risk for experiencing adverse events and worse health outcomes in healthcare settings, including in pediatric hospitals. Despite the knowledge that individuals who speak LOE have worse health outcomes, they are often excluded from research studies on the basis of language and there is a paucity of data on ways to address these known disparities. Our work aims to address this gap by generating knowledge to improve health outcomes for children with illness and their families with LEP. BODY: We describe an approach to developing a study with individuals marginalized due to using LOE for healthcare communication, specifically using semi-structured qualitative interviews. The premise of this study is participatory research-our overall goal with this systematic inquiry is to, in collaboration with patients and families with LOE, set an agenda for creating actionable change to address the health information disparities these patients and families experience. In this paper we describe our overarching study design principles, a collaboration framework in working with different stakeholders and note important considerations for study design and execution. CONCLUSIONS: We have a significant opportunity to improve our engagement with marginalized populations. We also need to develop approaches to including patients and families with LOE in our research given the health disparities they experience. Further, understanding lived experience is critical to advancing efforts to address these well-known health disparities. Our process to develop a qualitative study protocol can serve as an example for engaging this patient population and can serve as a starting point for other groups who wish to develop similar research in this area. Providing high-quality care that meets the needs of marginalized and vulnerable populations is important to achieving an equitable, high-quality health care system. Children and families who use a Language other than English (LOE) in English dominant regions for healthcare have worse health outcomes including a significantly increased risk of experiencing adverse events, longer lengths of stay in hospital settings, and receiving more unnecessary tests and investigations. Despite this, these individuals are often excluded from research studies and the field of participatory research has yet to meaningfully involve them. This paper aims to describe an approach to conducting research with a marginalized population of children and families due to using a LOE. We detail protocol development for a qualitative study exploring the lived experiences of patients and families who use a LOE during hospitalization. We aim to share considerations when conducting research within this population of families with LOE. We highlight learning applied from the field of patient-partner and child and family-centred research and note specific considerations for those with LOE. Developing strong partnerships and adopting a common set of research principles and collaborative framework underlies our approach and initial learnings, which we hope spark additional work in this area.
