Does the use of higher versus lower oxygen concentration improve neurodevelopmental outcomes at 18-24 months in very low birthweight infants?

BACKGROUND: Immediately after birth, the oxygen saturation is between 30 and 50%, which then increases to 85-95% within the first 10 min. Over the last 10 years, recommendations regarding the ideal level of the initial fraction of inspired oxygen (FiO2) for resuscitation in preterm infants have changed from 1.0, to room air to low levels of oxygen (< 0.3), up to moderate concentrations (0.3-0.65). This leaves clinicians in a challenging position, and a large multi-center international trial of sufficient sample size that is powered to look at safety outcomes such as mortality and adverse neurodevelopmental outcomes is required to provide the necessary evidence to guide clinical practice with confidence. METHODS: An international cluster, cross-over randomized trial of initial FiO2 of 0.3 or 0.6 during neonatal resuscitation in preterm infants at birth to increase survival free of major neurodevelopmental outcomes at 18 and 24 months corrected age will be conducted. Preterm infants born between 230/7 and 286/7 weeks' gestation will be eligible. Each participating hospital will be randomized to either an initial FiO2 concentration of either 0.3 or 0.6 to recruit for up to 12 months' and then crossed over to the other concentration for up to 12 months. The intervention will be initial FiO2 of 0.6, and the comparator will be initial FiO2 of 0.3 during respiratory support in the delivery room. The sample size will be 1200 preterm infants. This will yield 80% power, assuming a type 1 error of 5% to detect a 25% reduction in relative risk of the primary outcome from 35 to 26.5%. The primary outcome will be a composite of all-cause mortality or the presence of a major neurodevelopmental outcome between 18 and 24 months corrected age. Secondary outcomes will include the components of the primary outcome (death, cerebral palsy, major developmental delay involving cognition, speech, visual, or hearing impairment) in addition to neonatal morbidities (severe brain injury, bronchopulmonary dysplasia; and severe retinopathy of prematurity). DISCUSSION: The use of supplementary oxygen may be crucial but also potentially detrimental to preterm infants at birth. The HiLo trial is powered for the primary outcome and will address gaps in the evidence due to its pragmatic and inclusive design, targeting all extremely preterm infants. Should 60% initial oxygen concertation increase survival free of major neurodevelopmental outcomes at 18-24 months corrected age, without severe adverse effects, this readily available intervention could be introduced immediately into clinical practice. TRIAL REGISTRATION: The trial was registered on January 31, 2019, at ClinicalTrials.gov with the Identifier: NCT03825835.

Acute kidney injury and renal recovery following Fontan surgery.

Objectives: Acute kidney injury has been described after Fontan surgery, but the duration and outcomes are unknown. We sought to describe the incidence of and risk factors for acute kidney injury and the phenotype of renal recovery, and evaluate the impact of renal recovery phenotype on outcomes. Methods: All children who underwent a Fontan operation at a single center between 2009 and 2022 were included. Data collected included Fontan characteristics, vasopressor use, all measures of creatinine, and postoperative outcomes. Logistic regression models were used to assess predictors of acute kidney injury and the association between acute kidney injury and outcomes. Results: We enrolled 141 children (45% female). Acute kidney injury occurred in 100 patients (71%). Acute kidney injury duration was transient (<48 hours) in 77 patients (55%), persistent (2-7 days) in 15 patients (11%), more than 7 days in 4 patients (3%), and unknown in 4 patients (3%). Risk factors for acute kidney injury included higher preoperative indexed pulmonary vascular resistance (odds ratio, 3.90; P = .004) and higher postoperative inotrope score on day 0 (odds ratio, 1.13, P = .047). Risk factors for acute kidney injury duration more than 48 hours included absence of a fenestration (odds ratio, 3.43, P = .03) and longer duration of cardiopulmonary bypass (odds ratio, 1.22 per 15-minute interval, P = .01). Acute kidney injury duration more than 48 hours was associated with longer length of stay compared with transient acute kidney injury (median 18 days [interquartile range, 9-62] vs 10 days [interquartile range, 8-16], P = .006) and more sternal wound infections (17% vs 4%, P = .049). Conclusions: Acute kidney injury after the Fontan operation is common. The occurrence and duration of acute kidney injury have significant implications for postoperative outcomes.

Sustained inflation and chest compression versus 3:1 chest compression to ventilation ratio during cardiopulmonary resuscitation of asphyxiated newborns (SURV1VE): A cluster randomised controlled trial.

OBJECTIVE: In newborn infants requiring chest compression (CC) in the delivery room (DR) does continuous CC superimposed by a sustained inflation (CC+SI) compared with a 3:1 compression:ventilation (3:1 C:V) ratio decreases time to return of spontaneous circulation (ROSC). DESIGN: International, multicenter, prospective, cluster cross-over randomised trial. SETTING: DR in four hospitals in Canada and Austria, PARTICIPANTS: Newborn infants >28 weeks' gestation who required CC. INTERVENTIONS: Hospitals were randomised to CC+SI or 3:1 C:V then crossed over to the other intervention. MAIN OUTCOME MEASURE: The primary outcome was time to ROSC, defined as the duration of CC until an increase in heart rate >60/min determined by auscultation of the heart, which was maintained for 60 s. Sample size of 218 infants (109/group) was sufficient to detect a clinically important 33% reduction (282 vs 420 s of CC) in time to ROSC. Analysis was intention-to-treat. RESULTS: Patient recruitment occurred between 19 October 2017 and 22 September 2022 and randomised 27 infants (CC+SI (n=12), 3:1 C:V (n=15), two (one per group) declined consent). All 11 infants in the CC+SI group and 12/14 infants in the 3:1 C:V group achieved ROSC in the DR. The median (IQR) time to ROSC was 90 (60-270) s and 615 (174-780) s (p=0.0502 (log rank), p=0.16 (cox proportional hazards regression)) with CC+SI and 3:1 C:V, respectively. Mortality was 2/11 (18.2%) with CC+SI versus 8/14 (57.1%) with 3:1 C:V (p=0.10 (Fisher's exact test), OR (95% CI) 0.17; (0.03 to 1.07)). The trial was stopped due to issues with ethics approval and securing trial insurance as well as funding reasons. CONCLUSION: The time to ROSC and mortality was not statistical different between CC+SI and 3:1 C:V. TRIAL REGISTRATION: NCT02858583.

Patient factors and geographic barriers influencing excess time between paediatric and adult CHD care.

INTRODUCTION: Over 90% of children with CHD survive into adulthood and require lifelong cardiology care. Delays in care predispose patients to cardiac complications. We sought to determine the time interval to accessing adult CHD care beyond what was recommended by the referring paediatric cardiologist (excess time) and determine risk factors for prolonged excess time. MATERIALS AND METHODS: Retrospective cohort study including all patients in the province of Alberta, Canada, age 16-18 years at their last paediatric cardiology visit, with moderate or complex lesions. Excess time between paediatric and adult care was defined as the interval (months) between the final paediatric visit and the first adult visit, minus the recommended interval between these appointments. Patients whose first adult CHD appointment occurred earlier than the recommended interval were assigned an excess time of zero. RESULTS: We included 286 patients (66% male, mean age 17.6 years). Mean excess time was 7.9 ± 15.9 months. Twenty-nine (10%) had an excess time > 24 months. Not having a pacemaker (p = 0.03) and not needing cardiac medications at transfer (p = 0.02) were risk factors for excess time >3 months. Excess time was not influenced by CHD complexity. DISCUSSION: The mean delay to first adult CHD appointment was almost 8 months longer than recommended by referring paediatric cardiologists. Not having a pacemaker and not needing cardiac medication(s) were risk factors for excess time > 3 months. Greater outpatient resources are required to accommodate the growing number of adult CHD survivors.

Mental Health of Immigrant Children and Adolescents (6-17 Years) in Canada: Evidence from the Canadian Health Measures Survey.

BACKGROUND: Studies indicate a higher prevalence of mental health problems among immigrants, but findings on immigrant children and adolescents are mixed. We sought to understand the magnitude of differences in mental health indicators between immigrant and non-immigrant children and adolescents in Canada and the influence of age, sex, household income, and household education. METHODS: We completed a secondary analysis of data from the Canadian Health Measures Survey, using a pooled estimate method to combine data from four survey cycles. A weighted logistic regression was used to estimate the unadjusted and adjusted odds ratios with 95% confidence intervals. RESULTS: We found an association between the mental health of immigrant versus non-immigrant children and adolescents (6-17 years) as it relates to emotional problems and hyperactivity. Immigrant children and adolescents had better outcomes with respect to emotional problems and hyperactivity/inattention compared to non-immigrant children and adolescents. Lower household socioeconomic status was associated with poorer mental health in children and adolescents. CONCLUSION: No significant differences in overall mental health status were evident between immigrant and non-immigrant children and adolescents in Canada but differences exist in emotional problems and hyperactivity. Sex has an influence on immigrant child mental health that varies depending on the specific mental health indicator.

Family caregivers' emotional and communication needs in Canadian pediatric emergency departments.

OBJECTIVES: To describe the extent to which caregivers' emotional and communication needs were met during pediatric emergency department (PED) visits. Secondary objectives included describing the association of caregiver emotional needs, satisfaction with care, and comfort in caring for their child's illness at the time of discharge with demographic characteristics, caregiver experiences, and ED visit details. STUDY DESIGN: Electronic surveys with medical record review were deployed at ten Canadian PEDs from October 2018 -March 2020. A convenience sample of families with children <18 years presenting to a PED were enrolled, for one week every three months, for one year per site. Caregivers completed one in-PED survey and a follow-up survey, up to seven days post-visit. RESULTS: This study recruited 2005 caregivers who self-identified as mothers (74.3%, 1462/1969); mean age was 37.8 years (SD 7.7). 71.7% (1081/1507) of caregivers felt their emotional needs were met. 86.4% (1293/1496) identified communication with the doctor as good/very good and 83.4% (1249/1498) with their child's nurse. Caregiver involvement in their child's care was reported as good/very good 85.6% (1271/1485) of the time. 81.8% (1074/1313) of caregivers felt comfortable in caring for their child at home at the time of discharge. Lower caregiver anxiety scores, caregiver involvement in their child's care, satisfactory updates, and having questions adequately addressed positively impacted caregiver emotional needs and increased caregiver comfort in caring for their child's illness at home. CONCLUSION: Approximately 30% of caregivers presenting to PEDs have unmet emotional needs, over 15% had unmet communication needs, and 15% felt inadequately involved in their child's care. Family caregiver involvement in care and good communication from PED staff are key elements in improving overall patient experience and satisfaction.

Predictors of persisting pain in children with Juvenile Idiopathic Arthritis: a case control study nested in the ReACCh-Out cohort.

BACKGROUND: To identify baseline predictors of persisting pain in children with Juvenile Idiopathic Arthritis (JIA), relative to patients with JIA who had similar baseline levels of pain but in whom the pain did not persist. METHODS: We used data from the Research in Arthritis in Canadian Children emphasizing Outcomes (ReACCh-Out) inception cohort to compare cases of 'moderate persisting pain' with controls of 'moderate decreasing pain'. Moderate pain was defined as a Visual Analogue Scale (VAS) for pain measurement score of > 3.5 cm. Follow-up was minimum 3 years. Univariate and Multivariate logistic regression models ascertained baseline predictors of persisting pain. RESULTS: A total of 31 cases and 118 controls were included. Mean pain scores at baseline were 6.4 (SD 1.6) for cases and 5.9 (1.5) for controls. A greater proportion of cases than controls were females (77.4% vs 65.0%) with rheumatoid factor positive polyarthritis (12.9% vs 4.2%) or undifferentiated JIA (22.6% vs 8.5%). Oligoarthritis was less frequent in cases than controls (9.7% vs 33%). At baseline, cases had more active joints (mean of 11.4 vs 7.7) and more sites of enthesitis (4.6 vs 0.7) than controls. In the final multivariate regression model, enthesitis count at baseline (OR 1.40, CI 95% 1.19-1.76), female sex (4.14, 1.33-16.83), and the overall Quality of My Life (QoML) baseline score (0.82, 0.69-0.98) predicted development of persisting pain. CONCLUSIONS: Among newly diagnosed children with JIA with moderate pain, female sex, lower overall quality of life, and higher enthesitis counts at baseline predicted development of persisting pain. If our findings are confirmed, patients with these characteristics may be candidates for interventions to prevent development of chronic pain.

Just TRAC it! Transitioning Responsibly to Adult Care Using Smart Phone Technology.

PURPOSE: There is little evidence on whether smartphone technology influences transition readiness among adolescents with heart disease. Just TRAC it! is a method of using existing smartphone features (Notes, Calendar, Contacts, Camera) to manage personal health. We evaluated the impact of Just TRAC it! on self-management skills. METHODS: Randomized clinical trial of 16-18 year-olds with heart disease. Participants were randomly allocated 1:1 to either usual care (education session) or intervention (education session including Just TRAC it!). The primary outcome was change in TRANSITION-Q score between baseline, 3 and 6 months. Secondary outcomes were frequency of use and perceived usefulness of Just TRAC it! Analysis was intention-to-treat. RESULTS: We enrolled 68 patients (41% female, mean age 17.3 years), 68% having previous cardiac surgery and 26% had cardiac catheterization. TRANSITION-Q scores were similar at baseline and increased over time in both groups but were not significantly different between groups. Each additional point at the baseline score brought, on average, a 0.7-point increase in TRANSITION-Q score (95% CI 0.5-0.9) at each of 3 and 6 months. The Camera, Calendar and Notes apps were reported as most useful. All intervention participants would recommend Just TRAC it! to others. DISCUSSION: A nurse-led transition teaching with versus without Just TRAC it! improved transition readiness, with no significant difference between groups. Higher baseline TRANSITION-Q scores were associated with greater increase in scores over time. Participants had a positive reception to Just TRAC it! and would recommend it to others. Smartphone technology may be useful in transition education.

Prediction of future curve angle using prior radiographs in previously untreated idiopathic scoliosis: natural history from age 6 to after the end of growth (SOSORT 2022 award winner).

PURPOSE: Treatment selection for idiopathic scoliosis is informed by the risk of curve progression. Previous models predicting curve progression lacked validation, did not include the full growth/severity spectrum or included treated patients. The objective was to develop and validate models to predict future curve angles using clinical data collected only at, or both at and prior to, an initial specialist consultation in idiopathic scoliosis. METHODS: This is an analysis of 2317 patients with idiopathic scoliosis between 6 and 25 years old. Patients were previously untreated and provided at least one prior radiograph prospectively collected at first consult. Radiographs were re-measured blinded to the predicted outcome: the maximum Cobb angle on the last radiograph while untreated. Linear mixed-effect models were used to examine the effect of data from the first available visit (age, sex, maximum Cobb angle, Risser, and curve type) and from other visits while untreated (maximum Cobb angle) and time (from the first available radiograph to prediction) on the Cobb angle outcome. Interactions of the first available angle with time, of time with sex, and time with Risser were also tested. RESULTS: We included 2317 patients (83% of females) with 3255 prior X-rays where 71% had 1, 21.1% had 2, and 7.5% had 3 or more. Mean age was 13.9 ± 2.2yrs and 81% had AIS. Curve types were: 50% double, 26% lumbar/thoracolumbar-lumbar, 16% thoracic, and 8% other. Cobb angle at the first available X-ray was 20 ± 10° (0-80) vs 29 ± 13° (6-122) at the outcome visit separated by 28 ± 22mths. In the model using data at and prior to the specialist consult, larger values of the following variables predicted larger future curves: first available Cobb angle, Cobb angle on other previous X-ray, and time (with Time2 and Time3) to the target prediction. Larger values on the following variables predicted a smaller future Cobb angle: Risser and age at the first available X-ray, time*Risser and time*female sex interactions. Cross-validation found a median error of 4.5o with 84% predicted within 10°. Similarly, the model using only data from the first specialist consult had a median error of 5.5o with 80% of cases within 10° and included: maximum Cobb angle at first specialist consult, Time, Time2, age, curve type, and both interactions. CONCLUSIONS: The models can help clinicians predict how much curves would progress without treatment at future timepoints of their choice using simple variables. Predictions can inform treatment prescription or show families why no treatment is recommended. The nonlinear effects of time account for the rapid increase in curve angle at the beginning of growth and the slowed progression after maturity. These validated models predicted future Cobb angle with good accuracy in untreated idiopathic scoliosis over the full growth spectrum.

Validation of a Wound Tool for Assessment of Surgical Wounds in Infants.

BACKGROUND: Wound assessment is a critical part of the care of hospitalized infants in neonatal intensive care. Early recognition and initiation of appropriate treatment of wounds are imperative to facilitate wound healing and avoid complications such as secondary infection and wound dehiscence. There are, however, no validated tools for assessing surgical wounds in infants. PURPOSE: The aim of this study was to develop and interrogate a tool for the assessment of surgical wounds. Specific aims for the tool included interrater reliability (give a consistent and dependable result independent of user) and test criterion validity (give an accurate assessment of the wound compared with an expert). METHODS: This was an exploratory cohort study involving a structured wound tool applied by nursing staff to 40 surgical wounds. The wounds were also assessed by wound experts (a pediatric wound care nurse and a pediatric surgeon). Comparisons were made to elucidate estimates of reliability and validity. RESULTS: The wound tool demonstrated interrater reliability with intraclass correlation coefficient of 0.775 (95% CI, 0.665-0.862) as well as criterion validity with rank correlation coefficient of 0.55 (95% CI, 0.34-0.76) to 0.71 (95% CI, 0.53-0.88). To obtain 100% sensitivity to distinguish mild from moderate-severe wounds, a low cutoff score was needed. IMPLICATIONS FOR PRACTICE AND RESEARCH: Wound assessment continues to be a subjective exercise, even with the utilization of a tool. Additional research is needed for strategies to support the assessment of surgical wounds in infants. Such tools are needed for future research, particularly when multiple institutions are involved.

Efficacy and safety of antimicrobial stewardship prospective audit and feedback in patients hospitalised with COVID-19 (COVASP): a pragmatic, cluster-randomised, non-inferiority trial.

BACKGROUND: The COVID-19 pandemic has been associated with increased antimicrobial use despite low rates of bacterial co-infection. Prospective audit and feedback is recommended to optimise antibiotic prescribing, but high-quality evidence supporting its use for COVID-19 is absent. We aimed to study the efficacy and safety of prospective audit and feedback in patients admitted to hospital for the treatment of COVID-19. METHODS: COVASP was a prospective, pragmatic, non-inferiority, small-unit, cluster-randomised trial comparing prospective audit and feedback plus standard of care with standard of care alone in adults admitted to three hospitals in Edmonton, AB, Canada, with COVID-19 pneumonia. All patients aged at least 18 years who were admitted from the community to a designated study bed with microbiologically confirmed SARS-CoV-2 infection in the preceding 14 days were included if they had an oxygen saturation of 94% or lower on room air, required supplemental oxygen, or had chest-imaging findings compatible with COVID-19 pneumonia. Patients were excluded if they were transferred in from another acute care centre, enrolled in another clinical trial that involved antibiotic therapy, expected to progress to palliative care or death within 48 h of hospital admission, or managed by any member of the research team within 30 days of enrolment. COVID-19 unit and critical care unit beds were stratified and randomly assigned (1:1) to the prospective audit and feedback plus standard of care group or the standard of care group. Patients were masked to their bed assignment but the attending physician and study team were not. The primary outcome was clinical status on postadmission day 15, measured using a seven-point ordinal scale. We used a non-inferiority margin of 0·5. Analysis was by intention to treat. The trial is registered with ClinicalTrials.gov, NCT04896866, and is now closed. FINDINGS: Between March 1 and Oct 29, 2021, 1411 patients were screened and 886 were enrolled: 457 into the prospective audit and feedback plus standard of care group, of whom 429 completed the study, and 429 into the standard of care group, of whom 404 completed the study. Baseline characteristics were similar for both groups, with an overall mean age of 56·7 years (SD 17·3) and a median baseline ordinal scale of 4·0 (IQR 4·0-5·0). 301 audit and feedback events were recorded in the intervention group and 215 recommendations were made, of which 181 (84%) were accepted. Despite lower antibiotic use in the intervention group than in the control group (length of therapy 364·9 vs 384·2 days per 1000 patient days), clinical status at postadmission day 15 was non-inferior (median ordinal score 2·0 [IQR 2·0-3·0] vs 2·0 [IQR 2·0-4·0]; p=0·37, Mann-Whitney U test). Neutropenia was uncommon in both the intervention group (13 [3%] of 420 patients) and the control group (20 [5%] of 396 patients), and acute kidney injury occurred at a similar rate in both groups (74 [18%] of 421 patients in the intervention group and 76 [19%] of 399 patients in the control group). No intervention-related deaths were recorded. INTERPRETATION: This cluster-randomised clinical trial shows that prospective audit and feedback is safe and effective in optimising and reducing antibiotic use in adults admitted to hospital with COVID-19. Despite many competing priorities during the COVID-19 pandemic, antimicrobial stewardship should remain a priority to mitigate the overuse of antibiotics in this population. FUNDING: None.

Heal-me PiONEer (personalized online nutrition and exercise): An RCT assessing 2 levels of app-based programming in individuals with chronic disease.

Background App-based strategies are a promising solution to deliver nutrition and exercise interventions during social distancing. With limited RCT data in individuals with chronic disease, further information is required both to determine impact, and to guide delivery. The Heal-Me app is an evidence-based, theoretically informed nutrition and exercise solution that can be tailored for use across a range of individuals with chronic disease. As compared to controls receiving educational material, the aim of this study is to assess the acceptability, effectiveness, and cost of Heal-Me app programming delivered alongside two levels of dietitian and exercise-specialist support. Methods Heal-Me PiONEer is a 12-week, 3-arm RCT with randomization to one of three study groups (n=72 per group, 216 total). Group 1 (control: educational material), Group 2 (Heal-Me app + virtual group dietitian/exercise-specialist sessions), Group 3 (Heal-Me app + virtual group and 1-to-1 dietitian/exercise-specialist sessions). Inclusion criteria: adults with cancer, chronic lung disease or status post-transplantation from liver or lung transplant; previous completion of an exercise rehabilitation program; access to an internet-connected device. Study outcomes measured at study weeks 0 and 12 include: Primary - Lower Extremity Functional Scale; Secondary - virtual physical function tests, loneliness, resilience, anxiety, well-being and health-related quality of life; Exploratory outcomes - protein intake, behavioral beliefs around exercise and nutrition, adherence, adverse events, acceptability, and cost-utility. Conclusions The Heal-Me PiONEer RCT holds promise to provide a comprehensive understanding of the delivery and impact of app-based nutrition and exercise programming in a diverse group of participants with chronic disease.

Efficacy and safety of antimicrobial stewardship prospective audit and feedback in patients hospitalized with COVID-19: A protocol for a pragmatic clinical trial.

BACKGROUND: The use of broad-spectrum antibiotics is widespread in patients with COVID-19 despite a low prevalence of bacterial co-infection, raising concerns for the accelerated development of antimicrobial resistance. Antimicrobial stewardship (AMS) is vital but there are limited randomized clinical trial data supporting AMS interventions such as prospective audit and feedback (PAF). High quality data to demonstrate safety and efficacy of AMS PAF in hospitalized COVID-19 patients are needed. METHODS AND DESIGN: This is a prospective, multi-center, non-inferiority, pragmatic randomized clinical trial evaluating AMS PAF intervention plus standard of care (SOC) versus SOC alone. We include patients with microbiologically confirmed SARS-CoV-2 infection requiring hospital admission for severe COVID-19 pneumonia. Eligible ward beds and critical care unit beds will be randomized prior to study commencement at each participating site by computer-generated allocation sequence stratified by intensive care unit versus conventional ward in a 1:1 fashion. PAF intervention consists of real time review of antibacterial prescriptions and immediate written and verbal feedback to attending teams, performed by site-based AMS teams comprised of an AMS pharmacist and physician. The primary outcome is clinical status at post-admission day 15 measured using a 7-point ordinal scale. Patients will be followed for secondary outcomes out to 30 days. A total of 530 patients are needed to show a statistically significant non-inferiority, with 80% power and 2.5% one-sided alpha assuming standard deviation of 2 and the non-inferiority margin of 0.5. DISCUSSION: This study protocol presents a pragmatic clinical trial design with small unit cluster randomization for AMS intervention in hospitalized COVID-19 that will provide high-level evidence and may be adopted in other clinical situations. TRIAL REGISTRATION: This study is being performed at the University of Alberta and is registered at ClinicalTrials.gov (NCT04896866) on May 17, 2021.

Transition Preparation for Young Adolescents with Congenital Heart Disease: A Clinical Trial.

OBJECTIVE: To evaluate the impact of a novel nurse-led transition intervention program designed for young adolescents (age 13-14 years) with congenital heart disease (CHD). We hypothesized that the intervention would result in improved self-management skills and CHD knowledge. STUDY DESIGN: Single-center cluster randomized controlled trial of a nurse-led transition intervention vs usual care. The intervention group received a 1-hour individualized session with a cardiology nurse, focusing on CHD education and self-management. The primary end point was change in TRANSITION-Q (transition readiness) score between baseline and 6 months. The secondary end point was change in MyHeart score (CHD knowledge). RESULTS: We randomized 60 participants to intervention (n = 30) or usual care (n = 30). TRANSITION-Q score (range 0-100) increased from 49 ± 10 at baseline to 54 ± 9.0 at 6 months (intervention) vs 47 ± 14 to 44 ± 14 (usual care). Adjusted for baseline score, TRANSITION-Q scores at 1 and 6 months were greater in the intervention group (mean difference 5.9, 95% CI 1.3-10.5, P = .01). MyHeart score (range 0-100) increased from 48 ± 24 at baseline to 71 ± 16 at 6 months (intervention) vs 54 ± 24 to 57 ± 22 (usual care). Adjusted for baseline score, MyHeart scores at 1 and 6 months were greater in the intervention group (mean difference 19, 95% CI 12-26, P < .0001). Participants aged 14 years had a greater increase in TRANSITION-Q score at 6 months compared with 13-year-old participants (P < .05). CONCLUSIONS: A nurse-led program improved transition readiness and CHD knowledge among young adolescents. This simple intervention can be readily adopted in other healthcare settings. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02374892.

Higher versus Lower Oxygen Concentration during Respiratory Support in the Delivery Room in Extremely Preterm Infants: A Pilot Feasibility Study.

BACKGROUND: Optimal starting oxygen concentration for delivery room resuscitation of extremely preterm infants (<29 weeks) remains unknown, with recommendations of 21-30% based on uncertain evidence. Individual patient randomized trials designed to answer this question have been hampered by poor enrolment. HYPOTHESIS: It is feasible to compare 30% vs. 60% starting oxygen for delivery room resuscitation of extremely preterm infants using a change in local hospital policy and deferred consent approach. STUDY DESIGN: Prospective, single-center, feasibility study, with each starting oxygen concentration used for two months for all eligible infants. POPULATION: Infants born at 23 + 0-28 + 6 weeks' gestation who received delivery room resuscitation. Study interventions: Initial oxygen at 30% or 60%, increasing by 10-20% every minute for heart rate < 100 bpm, or increase to 100% for chest compressions. PRIMARY OUTCOME: Feasibility, defined by (i) achieving difference in cumulative supplied oxygen concentration between groups, and (ii) post-intervention rate consent >50%. RESULTS: Thirty-four infants were born during a 4-month period; consent was obtained in 63%. Thirty (n = 12, 30% group; n = 18, 60% group) were analyzed, including limited data from eight who died or were transferred before parents could be approached. Median cumulative oxygen concentrations were significantly different between the two groups in the first 5 min. CONCLUSION: Randomized control trial of 30% or 60% oxygen at the initiation of resuscitation of extremely preterm neonates with deferred consent is feasible. TRIAL REGISTRATION: Clinicaltrials.gov NCT03706586.

An assessment of the psychometric properties of the Stoplight Pain Scale in a Canadian paediatric emergency department.

OBJECTIVE: This study aimed to validate a novel, three faced, colour-coded, action-oriented tool: The Stoplight Pain Scale (SPS). METHODS: A prospective observational cohort study was conducted at a Canadian paediatric emergency department from November 2014 to February 2017. Patients aged 3 to 12 years and their caregivers were asked to rate pain using the SPS and the Faces Pain Scale-Revised (FPS-R). Pain was measured just before analgesia administration, 30 minutes after analgesia administration, and immediately following a painful procedure. RESULTS: A total of 227 patients were included; 26.9% (61/227) were 3 to 5 years old while 73.1% (166/227) were 6 to 12 years old. Using Cohen's κ, agreement for SPS and FPS-R was 'fair' for children (0.28 [95% confidence interval {CI} 0.20 to 0.36]) and 'poor' for caregivers (0.14 [95% CI 0.07 to 0.21]), at initial measurement. The SPS had 'fair' agreement between child and caregiver scores, (0.37 [95% CI 0.27 to 0.47]), compared to FPS-R which showed 'poor' agreement (0.20 [95% CI 0.12 to 0.29]). Absolute agreement between child and caregiver SPS scores improved with repeat exposure; 30 minutes after analgesia administration, caregivers and children had fair agreement (κ=0.38, 95% CI 0.28 to 0.48); they had moderate agreement directly following painful procedures (κ=0.46, 95% CI 0.34 to 0.59). Overall, 72.4% (139/192) of children and 60.2% (118/196) of caregivers preferred SPS over FPS-R. CONCLUSION: The SPS demonstrates fair agreement with FPS-R for children and fair-moderate agreement between children and caregivers; agreement improved with repeat use. The SPS is simple and easy to use; it may have a role in empowering direct child and family involvement in pain management.

A Typology of Transition Readiness for Adolescents with Congenital Heart Disease in Preparation for Transfer from Pediatric to Adult Care.

PURPOSE: To understand the effectiveness of a nurse-led transition intervention by analyzing qualitative data generated in the context of a clinical trial. DESIGN & METHODS: Qualitative study of a two-session transition intervention conducted by registered nurses at two sites. Adolescents aged 16-17 years with moderate or complex congenital heart disease (CHD) had been randomized to a two-session transition intervention or usual care. Session 1 emphasized patient education including creation of a health passport and goal setting. Session 2, two months later, emphasized self-management. Qualitative data extracted from intervention logs, field notes and audio recordings of the sessions were analyzed for content and themes. RESULTS: Data from 111 transition intervention sessions with 57 adolescents were analyzed. Creating a health passport, goal setting, and role-plays were the elements of the intervention most valued by participants. A typology of transition readiness was identified: 1) the independent adolescent (5%), already managing their own care; 2) the ready adolescent who was prepared for transition after completing the intervention (46%); 3) the follow-up needed adolescent who was still in need of extra coaching (26%), and 4) the at-risk adolescent who warranted immediate follow-up (14%). Baseline knowledge and transition surveys scores validated the typology. CONCLUSIONS: A two-session nursing intervention met the transition needs of approximately half of adolescents with CHD. However, additional transition-focused care was needed by 40% of participants (groups 3 and 4). PRACTICE IMPLICATIONS: These findings will guide pediatric nurses and other healthcare professionals to optimize an individualized approach for ensuring transition readiness for adolescents with CHD.

Coached, Coordinated, Enhanced Neonatal Transition (CCENT): protocol for a multicentre pragmatic randomised controlled trial of transition-to-home support for parents of high-risk infants.

INTRODUCTION: Having an infant admitted to the neonatal intensive care unit (NICU) is associated with increased parental stress, anxiety and depression. Enhanced support for parents may decrease parental stress and improve subsequent parent and child outcomes. The Coached, Coordinated, Enhanced Neonatal Transition (CCENT) programme is a novel bundled intervention of psychosocial support delivered by a nurse navigator that includes Acceptance and Commitment Therapy-based coaching, care coordination and anticipatory education for parents of high-risk infants in the NICU through the first year at home. The primary objective is to evaluate the impact of the intervention on parent stress at 12 months. METHODS AND ANALYSIS: This is a multicentre pragmatic randomised controlled superiority trial with 1:1 allocation to the CCENT model versus control (standard neonatal follow-up). Parents of high-risk infants (n=236) will be recruited from seven NICUs across three Canadian provinces. Intervention participants are assigned a nurse navigator who will provide the intervention for 12 months. Outcomes are measured at baseline, 6 weeks, 4, 12 and 18 months. The primary outcome measure is the total score of the Parenting Stress Index Fourth Edition Short Form at 12 months. Secondary outcomes include parental mental health, empowerment and health-related quality of life for calculation of quality-adjusted life years (QALYs). A cost-effectiveness analysis will examine the incremental cost of CCENT versus usual care per QALY gained. Qualitative interviews will explore parent and healthcare provider experiences with the intervention. ETHICS AND DISSEMINATION: Research ethics approval was obtained from Clinical Trials Ontario, Children's Hospital of Eastern Ontario Research Ethics Board (REB), The Hospital for Sick Children REB, UBC Children's and Women's REB and McGill University Health Centre REB. Results will be shared with Canadian level III NICUs, neonatal follow-up programmes and academic forums. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT03350243).

Assessing the efficacy and safety of hydroxychloroquine as outpatient treatment of COVID-19: a randomized controlled trial.

BACKGROUND: Identification of therapies to prevent severe COVID-19 remains a priority. We sought to determine whether hydroxychloroquine treatment for outpatients with SARS-CoV-2 infection could prevent hospitalization, mechanical ventilation or death. METHODS: This randomized controlled trial was conducted in Alberta during the first wave of the COVID-19 pandemic without direct contact with participants. Community-dwelling individuals with confirmed SARS-CoV-2 infection (by reverse transcription polymerase chain reaction [RT-PCR] viral ribonucleic acid test) within the previous 4 days, and symptom onset within the previous 12 days, were randomly assigned to oral hydroxychloroquine or matching placebo for 5 days. Enrolment began Apr. 15, 2020. The primary outcome was the composite of hospitalization, invasive mechanical ventilation or death within 30 days. Secondary outcomes included symptom duration and disposition at 30 days. Safety outcomes, such as serious adverse events and mortality, were also ascertained. Outcomes were determined by telephone follow-up and administrative data. RESULTS: Among 4919 individuals with a positive RT-PCR test, 148 (10.2% of a planned 1446 patients) were randomly assigned, 111 to hydroxychloroquine and 37 to placebo. Of the 148 participants, 24 (16.2%) did not start the study drug. Four participants in the hydroxychloroquine group met the primary outcome (4 hospitalizations, 0 mechanical ventilation, 4 survived to 30 days) and none in the placebo group. Hydroxychloroquine did not reduce symptom duration (hazard ratio 0.77, 95% confidence interval 0.49-1.21). Recruitment was paused on May 22, 2020, when a since-retracted publication raised concerns about the safety of hydroxychloroquine for hospitalized patients with COVID-19. Although we had not identified concerns in a safety review, enrolment was slower than expected among those eligible for the study, and cases within the community were decreasing. Recruitment goals were deemed to be unattainable and the trial was not resumed, resulting in a study underpowered to assess the effect of treatment with hydroxychloroquine and safety. INTERPRETATION: There was no evidence that hydroxychloroquine reduced symptom duration or prevented severe outcomes among outpatients with proven COVID-19, but the early termination of our study meant that it was underpowered.
