Effectiveness of Structured Care Coordination for Children With Medical Complexity: The Complex Care for Kids Ontario (CCKO) Randomized Clinical Trial.

Importance: Children with medical complexity (CMC) have chronic conditions and high health needs and may experience fragmented care. Objective: To compare the effectiveness of a structured complex care program, Complex Care for Kids Ontario (CCKO), with usual care. Design, Setting, and Participants: This randomized clinical trial used a waitlist variation for randomizing patients from 12 complex care clinics in Ontario, Canada, over 2 years. The study was conducted from December 2016 to June 2021. Participants were identified based on complex care clinic referral and randomly allocated into an intervention group, seen at the next available clinic appointment, or a control group that was placed on a waitlist to receive the intervention after 12 months. Intervention: Assignment of a nurse practitioner-pediatrician dyad partnering with families in a structured complex care clinic to provide intensive care coordination and comprehensive plans of care. Main Outcomes and Measures: Co-primary outcomes, assessed at baseline and at 6, 12, and 24 months postrandomization, were service delivery indicators from the Family Experiences With Coordination of Care that scored (1) coordination of care among health care professionals, (2) coordination of care between health care professionals and families, and (3) utility of care planning tools. Secondary outcomes included child and parent health outcomes and child health care system utilization and cost. Results: Of 144 participants randomized, 141 had complete health administrative data, and 139 had complete baseline surveys. The median (IQR) age of the participants was 29 months (9-102); 83 (60%) were male. At 12 months, scores for utility of care planning tools improved in the intervention group compared with the waitlist group (adjusted odds ratio, 9.3; 95% CI, 3.9-21.9; P < .001), with no difference between groups for the other 2 co-primary outcomes. There were no group differences for secondary outcomes of child outcomes, parent outcomes, and health care system utilization and cost. At 24 months, when both groups were receiving the intervention, no primary outcome differences were observed. Total health care costs in the second year were lower for the intervention group (median, CAD$17 891; IQR, 6098-61 346; vs CAD$37 524; IQR, 9338-119 547 [US $13 415; IQR, 4572-45 998; vs US $28 136; IQR, 7002-89 637]; P = .01). Conclusions and Relevance: The CCKO program improved the perceived utility of care planning tools but not other outcomes at 1 year. Extended evaluation periods may be helpful in assessing pediatric complex care interventions. Trial Registration: ClinicalTrials.gov Identifier: NCT02928757.

Randomized controlled trial evaluating a virtual parenting intervention for young children at risk of obesity: study protocol for Parenting Addressing Early Years Intervention with Coaching Visits in Toronto (PARENT) trial.

BACKGROUND: The prevalence of overweight (15%) and obesity (6%) in children under 5 years of age in Canada are high, and young children with overweight and obesity are at increased risk of the development of chronic disease(s) in adulthood. Prior research has demonstrated very few published trials on effective obesity prevention interventions in young children at risk of obesity, within primary healthcare settings. The aim of this study is to determine if 18-48-month-old children at risk for obesity, who are randomized to receive the Parents Together program (i.e., intervention group), have reduced body mass index z-score (zBMI), compared to those not receiving the intervention, at a 12-month follow-up. Secondary clinical outcomes between the intervention and control groups will be compared at 12 months. METHODS: A pragmatic, parallel group, 1:1, superiority, randomized control trial (RCT) through the TARGetKids! Practice Based Research Network will be conducted. Young children (ages 18-48 months) who are at increased risk for childhood obesity will be invited to participate. Parents who are enrolled in the intervention group will participate in eight weekly group sessions and 4-5 coaching visits, facilitated by a trained public health nurse. Children and parents who are enrolled in the control group will receive the usual health care. The primary outcome will be compared between intervention arms using an analysis of covariance (ANCOVA). Feasibility and acceptability will be assessed by parent focus groups and interviews, and fidelity to the intervention will be measured using nurse-completed checklists. A cost-effectiveness analysis (CEA) will be conducted. DISCUSSION: This study will aim to reflect the social, cultural, and geographic diversity of children in primary care in Toronto, Ontario, represented by an innovative collaboration among applied child health researchers, community health researchers, and primary care providers (i.e., pediatricians and family physicians in three different models of primary care). Clinical and implementation outcomes will be used to inform future research to test this intervention in a larger number, and diverse practices across diverse geographic settings in Ontario.

Cost-Effectiveness of a Quality Improvement Initiative for the Clinical Management of Children with Newly Diagnosed Immune Thrombocytopenia.

OBJECTIVE: To assess the cost-effectiveness of an evidence-informed institutional protocol for physicians that encouraged management of children with newly diagnosed immune thrombocytopenia (ITP) with observation over active therapy, where appropriate. STUDY DESIGN: We conducted a probabilistic cost-effectiveness analysis from an institutional perspective using a decision tree with a 1 year time horizon. Patient-level data were retrospectively ascertained for children diagnosed in pre-protocol (2007-2009) and post-protocol (2013-2018) time periods. ITP resolution was defined as achieving a sustained platelet count of >100 × 103/µL at 9-12 months after diagnosis. Outpatient care and inpatient costs were obtained from the institution and provincial sources. Intervention costs accounted for quality improvement initiative preparation and staff physician training. Incremental costs, incremental effects, and CIs were calculated from 10 000 model iterations. RESULTS: Forty-eight patients were followed for 1 year in the pre-protocol period and 84 in the post-protocol period. After protocol implementation, an average cost savings per child managed of $2055 (95% CI: $656, $3890) Canadian Dollars was observed, as was a higher proportion of resolved ITP cases. The implementation strategy remained less costly and more effective in 99.7% of model iterations. CONCLUSIONS: Implementation of an evidence-informed institutional protocol to guide physicians toward increased uptake of observation over active therapy when managing children with newly diagnosed ITP resulted in significant cost savings on a per case basis, even after accounting for training-related costs. Though the long-term cost implications regarding the sustainability of the intervention are not yet known, it is anticipated that continued institutional savings could occur.

Cost-effectiveness of Intermittent vs Continuous Pulse Oximetry Monitoring in Infants Hospitalized With Stabilized Bronchiolitis.

Importance: Pulse oximetry is a noninvasive technology that is integral to the supportive care of hospitalized infants with bronchiolitis. A multicenter, randomized trial comparing the effectiveness of intermittent vs continuous pulse oximetry found similar length of hospital stay and safety outcomes, and greater nursing satisfaction, with intermittent monitoring. Objectives: To evaluate the cost-effectiveness of intermittent vs continuous pulse oximetry in hospitalized infants with stabilized bronchiolitis. Design, Setting, and Participants: An economic evaluation concurrent with a randomized trial in community and tertiary children's hospitals in Ontario, Canada, was conducted using a probabilistic analysis. Patients were enrolled from November 1, 2016, to May 31, 2019. Data included infants aged 4 weeks to 24 months hospitalized with bronchiolitis, with or without supplemental oxygen, after stabilization. The cost-effectiveness analysis adopted a societal and health care system perspective and a time horizon from hospitalization to 15 days post-discharge. Patient level direct health care costs and indirect costs were included. Health resource use, costs, and clinical outcomes were obtained from trial data. Publicly available pricing resources were used to supplement costs. Ranges for sensitivity analysis were based on 95% confidence intervals of the trial data. All costs were reported in 2021 Canadian dollars. Interventions: Intermittent (every 4 hours) vs continuous pulse oximetry using an oxygen saturation target of 90% or higher. Main Outcomes and Measures: Costs and incremental costs. Results: Trial data from 229 infants (median [IQR] age, 4.0 [2.2-8.5] months; 136 boys [59.4%], 93 girls [40.6%]) were included. Mean societal costs per patient were $6879 (95% CI, $3393 to $12 317) in the intermittent and $7428 (95% CI, $1743 to $25 011) in the continuous group with a mean incremental cost of -$548 (95% CI, -$18 486 to $8105). Mean health care system costs per patient were $4195 (95% CI, $1191 to $9461) in the intermittent and $4716 (95% CI, $335 to $22 093) in the continuous group (incremental cost, -$520; 95% CI, -$18 286 to $7358). The mean effect measure of length of stay was similar between the 2 groups: 37.4 hours (95% CI, 1.0 to 137.7 hours) in the intermittent group and 38.5 hours (95% CI, 0 to 237.1 hours) in the continuous group. One-way sensitivity analyses on all variables revealed that the findings were robust and the incremental costs were not sensitive to the uncertainty within the defined ranges. Conclusions and Relevance: In this prospective economic evaluation study, we found that costs were similar for intermittent and continuous pulse oximetry considering societal and health care perspectives. Given that clinical outcomes between monitoring strategies are comparable and that other practice considerations favor intermittent monitoring, these findings provide additional information that support the use of intermittent monitoring in hospitalized infants with stabilized bronchiolitis.

Implementing a Care Coordination Strategy for Children with Medical Complexity in Ontario, Canada: A Process Evaluation.

Introduction: A provincial strategy to expand care coordination and integration of care for children with medical complexity (CMC) was launched in Ontario, Canada in 2015. A process evaluation of the roll-out examined the processes, mechanisms of impact, and contextual factors affecting the implementation of the Complex Care for Kids Ontario (CCKO) intervention strategy. Methods: This process evaluation was conducted and analyzed according to the United Kingdom Medical Research Council (UK-MRC) process evaluation framework. To evaluate the implementation of the CCKO intervention, a multi-method study design was used, including semi-structured interviews with 38 key informants and 10 families of CMC involved in CCKO. To further understand implementation details across regional sites, provincial-level implementation plans, and process documents were reviewed. Discussion: Strengths of CCKO included novel collaborations and partnerships between complex care teams, community partners and regional sites. Issues relating to communication and coordination across care sectors created challenges to holistic care coordination objectives. Provincial system fragmentation limited the ability of CCKO to provide seamless care coordination due to the multiple care sectors involved. Conclusion: This study adds to the understanding of the processes involved in a population-level care coordination intervention for CMC. Lessons learned through CCKO can help facilitate reproducibility and necessary adjustments of the intervention in different settings.

Prevalence, Cost, and Variation in Cost of Pediatric Hospitalizations in Ontario, Canada.

Importance: Identifying conditions that could be prioritized for research based on health care system burden is important for developing a research agenda for the care of hospitalized children. However, existing prioritization studies are decades old or do not include data from both pediatric and general hospitals. Objective: To assess the prevalence, cost, and variation in cost of pediatric hospitalizations at all general and pediatric hospitals in Ontario, Canada, with the aim of identifying conditions that could be prioritized for future research. Design, Setting, and Participants: This population-based cross-sectional study used health administrative data from 165 general and pediatric hospitals in Ontario, Canada. Children younger than 18 years with an inpatient hospital encounter between April 1, 2014, and March 31, 2019, were included. Main Outcomes and Measures: Condition-specific prevalence, cost of pediatric hospitalizations, and condition-specific variation in cost per inpatient encounter across hospitals. Variation in cost was evaluated using (1) intraclass correlation coefficient (ICC) and (2) number of outlier hospitals. Costs were adjusted for inflation to 2018 US dollars. Results: Overall, 627 314 inpatient hospital encounters (44.8% among children younger than 30 days and 53.0% among boys) at 165 hospitals (157 general and 8 pediatric) costing $3.3 billion were identified. A total of 408 003 hospitalizations (65.0%) and $1.4 billion (43.8%) in total costs occurred at general hospitals. Among the 50 most prevalent and 50 most costly conditions (of 68 total conditions), the top 10 highest-cost conditions accounted for 55.5% of all costs and 48.6% of all encounters. The conditions with highest prevalence and cost included low birth weight (86.2 per 1000 encounters; $676.3 million), preterm newborn (38.0 per 1000 encounters; $137.4 million), major depressive disorder (20.7 per 1000 encounters; $78.3 million), pneumonia (27.3 per 1000 encounters; $71.6 million), other perinatal conditions (68.0 per 1000 encounters; $65.8 million), bronchiolitis (25.4 per 1000 encounters; $54.6 million), and neonatal hyperbilirubinemia (47.9 per 1000 encounters; $46.7 million). The highest variation in cost per encounter among the most costly medical conditions was observed for 2 mental health conditions (other mental health disorders [ICC, 0.28] and anxiety disorders [ICC, 0.19]) and 3 newborn conditions (intrauterine hypoxia and birth asphyxia [ICC, 0.27], other perinatal conditions [ICC, 0.17], and surfactant deficiency disorder [ICC, 0.17]). Conclusions and Relevance: This population-based cross-sectional study of hospitalized children identified several newborn and mental health conditions as having the highest prevalence, cost, and variation in cost across hospitals. Findings of this study can be used to develop a research agenda for the care of hospitalized children that includes general hospitals and to ultimately build a more substantial evidence base and improve patient outcomes.

The Transitions to Long-term In Home Ventilator Engagement Study (Transitions to LIVE): study protocol for a pragmatic randomized controlled trial.

BACKGROUND OVERVIEW AND RATIONALE: We co-developed a multi-component virtual care solution (TtLIVE) for the home mechanical ventilation (HMV) population using the aTouchAway™ platform (Aetonix). The TtLIVE intervention includes (1) virtual home visits; (2) customizable care plans; (3) clinical workflows that incorporate reminders, completion of symptom profiles, and tele-monitoring; and (4) digitally secure communication via messaging, audio, and video calls; (5) Resource library including print and audiovisual material. OBJECTIVES AND BRIEF METHODS: Our primary objective is to evaluate the TtLIVE intervention compared to a usual care control group using an eight-center, pragmatic, parallel-group single-blind (outcome assessors) randomized controlled trial. Eligible patients are children and adults newly transitioning to HMV in Ontario, Canada. Our target sample size is 440 participants (220 each arm). Our co-primary outcomes are a number of emergency department (ED) visits in the 12 months after randomization and change in family caregiver (FC) reported Pearlin Mastery Scale score from baseline to 12 months. Secondary outcomes also measured in the 12 months post randomization include healthcare utilization measured using a hybrid Ambulatory Home Care Record (AHCR-hybrid), FC burden using the Zarit Burden Interview, and health-related quality of life using the EQ-5D. In addition, we will conduct a cost-utility analysis over a 1-year time horizon and measure process outcomes including healthcare provider time using the Care Coordination Measurement Tool. We will use qualitative interviews in a subset of study participants to understand acceptability, barriers, and facilitators to the TtLIVE intervention. We will administer the Family Experiences with Care Coordination (FECC) to interview participants. We will use Poisson regression for a number of ED visits at 12 months. We will use linear regression for the Pearlin Mastery scale score at 12 months. We will adjust for the baseline score to estimate the effect of the intervention on the primary outcomes. Analysis of secondary outcomes will employ regression, causal, and linear mixed modeling. Primary analysis will follow intention-to-treat principles. We have Research Ethics Board approval from SickKids, Children's Hospital Eastern Ontario, McMaster Children's Hospital, Children's Hospital-London Health Sciences, Sunnybrook Hospital, London Health Sciences, West Park Healthcare Centre, and Ottawa Hospital. DISCUSSION: This pragmatic randomized controlled single-blind trial will determine the effectiveness and cost-effectiveness of the TtLIVE virtual care solution compared to usual care while providing important data on patient and family experience, as well as process measures such as healthcare provider time to deliver the intervention.

Managing Obesity in Young Children: A Multiple Methods Study Assessing Feasibility, Acceptability, and Implementation of a Multicomponent, Family-Based Intervention.

Background: We developed a multicomponent, family-based intervention for young children with obesity consisting of parent group sessions, home nursing visits, and multidisciplinary clinical encounters. Our objective was to assess intervention feasibility, acceptability, and implementation. Methods: From 2017 to 2020, we conducted a multiple methods study in the obesity management clinic at a tertiary children's hospital (Toronto, Canada). We included 1-6 year olds with a body mass index ≥97th percentile and their parents; we also included health care providers (HCPs) who delivered the intervention. To assess feasibility, we performed a pilot randomized controlled trial (RCT) comparing the intervention to usual care. To explore acceptability, we conducted parent focus groups. To explore implementation, we examined contextual factors with HCPs using the Consolidated Framework for Implementation Research. Results: There was a high level of ineligibility (n = 34/61) for the pilot RCT. Over 21 months, 11 parent-child dyads were recruited; of 6 randomized to the intervention, 3 did not participate in group sessions or home visits. In focus groups, themes identified by parents (n = 8) related to information provided at referral; fit between the intervention and patient needs; parental gains from participating in the intervention; and feasibility of group sessions. HCPs (n = 10) identified contextual factors that were positively and negatively associated with intervention implementation. Conclusions: We encountered challenges related to intervention feasibility, acceptability, and implementation. Lessons learned from this study will inform the next iteration of our intervention and are relevant to intervention development and implementation for young children with obesity.

Immediate versus delayed sequential bilateral cataract surgery in children: a cost-effectiveness analysis.

BACKGROUND/AIMS: Children with bilateral cataracts may undergo immediate sequential bilateral cataract surgery (ISBCS), which involves surgery on both eyes during the same general anaesthesia, or delayed sequential bilateral cataract surgery (DSBCS), which involves operating on each eye on separate days and requires a second anaesthesia. ISBCS is viewed with caution because of the risk of bilateral endophthalmitis. Proponents of ISBCS emphasise that the incidence of serious complications is low and is outweighed by benefits such as avoidance of multiple anaesthesia, faster visual rehabilitation and potential for decreased costs. However, there is a paucity of literature regarding the cost-effectiveness of ISBCS in children. We conducted a cost-effectiveness analysis to determine whether ISBCS is more cost-effective than DSBCS from the societal and health system perspectives in Ontario, Canada, which has a universal, single-payer system. METHODS: A retrospective analysis of children who underwent ISBCS or DSBCS at a tertiary referral paediatric hospital was conducted. A decision tree was constructed using TreeAge Pro 2018 software. Clear visual axis was the measure of effectiveness. A time horizon of 8 weeks postoperatively was adopted. Both direct and indirect costs were included. RESULTS: Fifty-three children were included, 37 in the ISBCS group and 16 in the DSBCS group. ISBCS and DSBCS were equally effective. ISBCS resulted in cost-savings of $3,776 (95% CI:-$4,641 to $12,578) CAD, per patient, from the societal perspective and $2,200 (95% CI:-$5,615 to $10,373) CAD per patient from the health system perspective. CONCLUSION: ISBCS was less costly than DSBCS from both societal and health system perspectives while being equally effective.

Process Evaluation of a Hub-and-Spoke Model to Deliver Coordinated Care for Children with Medical Complexity across Ontario: Facilitators, Barriers and Lessons Learned.

BACKGROUND: Complex Care for Kids Ontario (CCKO) is a multi-year strategy aimed at expanding a hub-and-spoke model to deliver coordinated care for children with medical complexity (CMC) across Ontario. OBJECTIVE: This paper aims to identify the facilitators, barriers and lessons learned from the implementation of the Ontario CCKO strategy. METHOD: Alongside an outcome evaluation of the CCKO strategy, we conducted a process evaluation to understand the implementation context, process and mechanisms. Semi-structured interviews were conducted with 38 healthcare leaders, clinicians and support staff from four regions involved in CCKO care delivery and/or governance. RESULTS: Facilitators to CCKO implementation were sustained engagement of system-wide stakeholders, inter-organizational partnerships, knowledge sharing and family engagement. Barriers to CCKO implementation were resources and funding, fragmentation of care, aligning perspectives between providers and clinical staff recruitment and retention. CONCLUSION: A flexible approach is required to implement a complex, multi-centre policy strategy. Other jurisdictions considering such a model of care delivery would benefit from attention to contextual variations in implementation setting, building cross-sector engagement and buy-in, and offering continuous support for modifications to the intervention as and when required.

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).

Cost-effectiveness of preferred fluids versus electrolytes in pediatric gastroenteritis.

BACKGROUND: While electrolyte maintenance solution is recommended and commonly used in pediatric gastroenteritis, it can be more costly and less palatable than preferred fluids such as apple juice. OBJECTIVE: To assess the incremental cost-effectiveness of apple juice/preferred fluids versus electrolyte maintenance solution in reducing treatment failures in children in an emergency department from societal and health care perspectives. METHODS: A probabilistic cost-effectiveness analysis was performed using clinical trial and chart data. All intervention, and direct and indirect costs were included, with a 14-day time horizon. Cost-effectiveness was examined by calculating the difference in mean number of treatment failures and mean cost/patient between treatment groups. The probabilistic point estimate and 95% confidence intervals for incremental costs and incremental effectiveness were determined. RESULTS: The apple juice strategy was less costly than electrolytes with average per child savings of CAD $171 (95% CI $22 to $1097) from a societal perspective, and $147 (95% CI $23 to $1056) from a health care perspective. There were 0.08 fewer treatment failures per child (95% CI - 0.15 to - 0.02). The higher electrolyte maintenance solution cost was due to more frequent hospitalizations, ongoing care, and greater lost parental productivity due to additional medical visits. CONCLUSION: Apple juice/preferred fluids strategy was dominant over electrolytes in the treatment of children with minimal dehydration secondary to acute gastroenteritis as this option yielded fewer treatment failures and a lower societal cost. Given the high prevalence of acute gastroenteritis, this approach may result in significant cost savings while leading to improved clinical outcomes.

RéSUMé: CONTEXTE: Bien que la solution de maintien des électrolytes soit recommandée et couramment utilisée dans les gastro-entérites pédiatriques, elle peut être plus coûteuse et moins agréable au goût que les liquides préférés tels que le jus de pomme. OBJECTIF: Évaluer le rapport coût-efficacité supplémentaire du jus de pomme/des liquides préférés par rapport à des électrolytes pour réduire les échecs de traitement chez les enfants dans un service d'urgence, du point de vue de la société et des soins de santé. LES MéTHODES: Une analyse probabiliste de la rentabilité a été réalisée en utilisant les données des essais cliniques et des dossiers. Tous les coûts d'intervention, directs et indirects, ont été inclus, avec un horizon temporel de 14 jours. La rentabilité a été examinée en calculant la différence du nombre moyen d'échecs de traitement et du coût/patient moyen entre les groupes de traitement. L'estimation ponctuelle probabiliste et les intervalles de confiance à 95% pour les coûts différentiels et l'efficacité différentielle ont été déterminés. RéSULTATS: La stratégie du jus de pomme était moins coûteuse que les électrolytes, avec des économies moyennes par enfant de 171 $ CAD (IC à 95 % : 22 $ à 1097 $) du point de vue sociétal et de 147 $ (IC à 95 % : 23 $ à 1056 $) du point de vue des soins de santé. Il y a eu 0,08 échec de traitement en moins par enfant (IC 95 % : -0,15 à -0,02). Le coût plus élevé des électrolytes est dû à des hospitalisations plus fréquentes, à des soins continus et à une plus grande perte de productivité des parents en raison de visites médicales supplémentaires. CONCLUSION: La stratégie du jus de pomme/des liquides préférés a été dominante sur les électrolytes dans le traitement des enfants présentant une déshydratation minimale secondaire à une gastro-entérite aiguë, car cette option a permis de réduire les échecs du traitement et le coût pour la société. Compte tenu de la prévalence élevée de la gastro-entérite aiguë, cette approche peut entraîner des économies de coûts significatives tout en améliorant les résultats cliniques.

A Cost-Utility Analysis of Switching from Reference to Biosimilar Infliximab Compared to Maintaining Reference Infliximab in Adult Patients with Crohn's Disease.

BACKGROUND AND AIMS: Lower-cost biosimilar infliximab may address affordability concerns in the treatment of adults with Crohn's disease (CD), however, evidence regarding the cost-effectiveness of switching from reference to biosimilar is warranted. The aim of this research was to assess the incremental cost of switching from treatment with reference infliximab to biosimilar compared with maintaining reference infliximab in adults with CD per quality-adjusted life year (QALY) gained. METHODS: A probabilistic cohort Markov model with 8-week cycle lengths was constructed to estimate the incremental costs and effects of switching over a 5-year time horizon from a public payer perspective. Base-case clinical inputs were obtained from NOR-SWITCH subgroup analyses and other published trials. Costs were obtained from Canadian sources. A total of 10,000 simulations were run. Sensitivity analysis was used to test the robustness of the results to variations in uncertain parameters. RESULTS: Switching to biosimilar infliximab was less costly but also less effective with incremental savings of $46,194 (95% confidence interval [CI]: $42,420, $50,455) and a loss in QALYs of -0.13 (95% CI: -0.16, -0.07). Eighty-three per cent of the simulations demonstrated incremental cost savings and an incremental loss of effectiveness. The model was sensitive to differences in rates of disease worsening between reference and biosimilar infliximab. CONCLUSIONS: While biosimilar infliximab is associated with incremental savings for patients on maintenance therapy who are switched from reference infliximab, funding decision makers must decide whether a small loss of effectiveness is justified. Further evidence will help to inform reimbursement policy.

Intermittent vs Continuous Pulse Oximetry in Hospitalized Infants With Stabilized Bronchiolitis: A Randomized Clinical Trial.

Importance: There is low level of evidence and substantial practice variation regarding the use of intermittent or continuous monitoring in infants hospitalized with bronchiolitis. Objective: To compare the effect of intermittent vs continuous pulse oximetry on clinical outcomes. Design, Setting, and Participants: This multicenter, pragmatic randomized clinical trial included infants 4 weeks to 24 months of age who were hospitalized with bronchiolitis from November 1, 2016, to May 31, 2019, with or without supplemental oxygen after stabilization at community and children's hospitals in Ontario, Canada. Interventions: Intermittent (every 4 hours, n = 114) or continuous (n = 115) pulse oximetry, using an oxygen saturation target of 90% or higher. Main Outcomes and Measures: The primary outcome was length of hospital stay from randomization to discharge. Secondary outcomes included length of stay from inpatient unit admission to discharge and outcomes measured from randomization: medical interventions, safety (intensive care unit transfer and revisits), parent anxiety and workdays missed, and nursing satisfaction. Results: Among 229 infants enrolled (median [IQR] age, 4.0 [2.2-8.5] months; 136 [59.4%] male; 101 [44.1%] from community hospital sites), the median length of hospital stay from randomization to discharge was 27.6 hours (interquartile range [IQR], 18.8-49.6 hours) in the intermittent group and 25.4 hours (IQR, 18.3-47.6 hours) in the continuous group (difference of medians, 2.2 hours; 95% CI, -1.9 to 6.3 hours; P = .17). No significant differences were observed between the intermittent and continuous groups in the median length of stay from inpatient unit admission to discharge: 49.1 (IQR, 37.2-87.0) hours vs 46.0 (IQR, 32.5-73.8) hours (P = .13) or in frequencies or durations of hospital interventions, such as oxygen supplementation initiation: 4 of 114 (3.5%) vs. 9 of 115 (7.8%) (P = .16) and median duration of oxygen supplementation: 20.6 (IQR, 7.6-46.1) hours vs. 21.4 (11.6-52.9) hours (P = .66). Similarly, there were no significant differences in frequencies of intensive care unit transfer: 1 of 114 (0.9%) vs 2 of 115 (2.7%) (P = .76); readmission to hospital: 3 of 114 (2.6%) in the intermittent group vs 4 of 115 (3.5%) in the continuous group (P > .99); parent anxiety: mean (SD) parent anxiety score, 2.9 (0.9) in the intermittent group vs 2.8 (0.9) in the continuous group (P = .40); or parent workdays missed: median workdays missed, 1.5 (IQR, 0.5-3.0) vs 1.5 (IQR, 0.5-2.5) (P = .36). Mean (SD) nursing satisfaction with monitoring was significantly greater in the intermittent group: 8.6 (1.7) vs 7.1 (2.8) of 10 workdays; the mean difference was 1.5 (95% CI, 0.9-2.2; P < .001). Conclusions and Relevance: In this randomized clinical trial, among infants hospitalized with stabilized bronchiolitis with and without hypoxia and managed using an oxygen saturation target of 90% or higher, clinical outcomes, including length of hospital stay and safety, were similar with intermittent vs continuous pulse oximetry. Nursing satisfaction was greater with intermittent monitoring. Given that other important clinical practice considerations favor less intense monitoring, these findings support the standard use of intermittent pulse oximetry in stable infants hospitalized with bronchiolitis.

Protocol for a cost-utility analysis of neurostimulation and intensive camp-based therapy for children with perinatal stroke and hemiparesis based on a multicentre clinical trial.

INTRODUCTION: Perinatal stroke leads to cerebral palsy (CP) and lifelong disability for thousands of Canadian children. Hemiparesis, referring to impaired functionality in one side of the body, is a common complication of perinatal stroke. Standard long-term care for hemiparetic CP focuses on rehabilitation therapies. Early research suggests that patients with hemiparesis may benefit from adjunctive neuromodulation treatments such as transcranial direct current stimulation (tDCS). tDCS uses electric current to stimulate targeted areas of the brain non-invasively, potentially enhancing the effects of motor learning therapies. This protocol describes an economic evaluation to be conducted alongside a randomised controlled trial (RCT) to assess the incremental cost of tDCS added to a camp-based therapy compared with camp-based therapy alone per quality-adjusted life year (QALY) gained in children with hemiparetic CP. METHODS AND ANALYSIS: The Stimulation for Perinatal Stroke Optimising Recovery Trajectories (SPORT) trial is a multicentre RCT evaluating tDCS added to a 2-week camp-based therapy for children aged 6-18 years with perinatal ischaemic stroke and disabling hemiparetic CP affecting the upper limb. Outcomes are assessed at baseline, 1 week, 2 months and 6 months following intervention. Cost and quality of life data are collected at baseline and 6 months and results will be used to conduct a cost-utility analysis (CUA). The evaluation will be conducted from the perspectives of the public healthcare system and society. The CUA will be conducted over a 6-month time horizon. ETHICS AND DISSEMINATION: Ethical approval for the SPORT trial and the associated economic evaluation has been given by the research ethics boards at each of the study sites. The findings of the economic evaluation will be submitted for publication in a peer reviewed academic journal and submitted for presentation at conference.

A Cost Analysis of Pulse Oximetry as a Determinant in the Decision to Admit Infants With Mild to Moderate Bronchiolitis.

OBJECTIVES: A previous randomized controlled trial showed that artificially elevating the pulse oximetry display resulted in fewer hospitalizations with no worse outcomes. This suggests that management decisions based mainly on pulse oximetry may unnecessarily increase health care costs. This study assessed the incremental cost of altered relative to true oximetry in infants with mild to moderate bronchiolitis. METHODS: A cost analysis was undertaken from the health care system and societal perspectives using patient-level data from the randomized controlled trial, with a 5-day time horizon after emergency department visit. Infants aged 4 weeks to 12 months with mild to moderate bronchiolitis were randomized to pulse oximetry measurements with true or altered saturation values displayed by artificially increasing saturation 3% points above true values. Direct and indirect health care costs were measured. Sensitivity analyses were performed to assess parameter uncertainty. RESULTS: From the health care system perspective, the average cost per patient was Can $1155 for altered oximetry and $1967 for true oximetry, with a net savings of $812. From a societal perspective, the average cost per patient was $1559 for altered oximetry and $2473 for true oximetry, with a net savings of $914. Probabilistic analyses demonstrated that altered oximetry remained the less costly study group, with an average savings of $810 (95% confidence interval, $748-$872) from the health care system perspective and $910 (95% confidence interval, $848-$973) from the societal system perspective. CONCLUSIONS: Reliance on oximetry as a major determinant in the decision to hospitalize infants with mild to moderate bronchiolitis is associated with significantly greater costs.

Time Driven Activity Based Costing of Management Pathways for Vesicoureteral Reflux.

INTRODUCTION: The approach to the management of vesicoureteral reflux remains variable despite being a common pediatric diagnosis, which makes costing unpredictable. The aim of our study is to employ time driven activity based costing to characterize institutional costs of 3 management pathways for vesicoureteral reflux. METHODS: We developed process maps for vesicoureteral reflux management based on practice guidelines applicable to a hypothetical female patient with vesicoureteral reflux index with grade 3 unilateral reflux without bowel bladder dysfunction at our institution. The costs of 3 management pathways were described, including watch and wait, minimally invasive endoscopic surgery with dextranomer/hyaluronic acid and open re-implantation surgery. Costs for each pathway were calculated using the capacity cost rate ($/minute) for institutional resources and time estimates of resource use captured through direct observation and electronic medical record data. Clinical outcomes such as the breakthrough urinary tract infections or renal scarring were not addressed in this cost description. RESULTS: A substantial range of total costs ($CAD) was observed for all pathways including watch and wait ($1,683.58 to $2,041.12), minimally invasive endoscopic surgery ($2,616.35 to $4,012.89) and open re-implantation surgery ($3,317.76 to $3,924.82). Total costs for a single dimercaptosuccinic acid scan accounted for 8% to 15% of any pathway's overall costs. Material costs for voiding cystourethrogram imaging and endoscopic surgery were high at 59% and 64% to 76% of their individual total costs, respectively. For open re-implantation surgery, high costs were attributable to the longer use of operating room space and inpatient postoperative stay. CONCLUSIONS: Time driven activity based costing demonstrates significant cost variability in vesicoureteral reflux treatment modalities and identified local cost drivers to target. Results from this study may be used to inform future cost-effectiveness analyses.

Recruitment of adolescents with suicidal ideation in the emergency department: lessons from a randomized controlled pilot trial of a youth suicide prevention intervention.

BACKGROUND: Emergency Departments (EDs) are a first point-of-contact for many youth with mental health and suicidality concerns and can serve as an effective recruitment source for randomized controlled trials (RCTs) of mental health interventions. However, recruitment in acute care settings is impeded by several challenges. This pilot RCT of a youth suicide prevention intervention recruited adolescents aged 12 to 17 years presenting to a pediatric hospital ED with suicide related behaviors. METHODS: Recruitment barriers were identified during the initial study recruitment period and included: the time of day of ED presentations, challenges inherent to study presentation, engagement and participation during an acute presentation, challenges approaching and enrolling acutely suicidal patients and families, ED environmental factors, and youth and parental concerns regarding the study. We calculated the average recruitment productivity for published trials of adolescent suicide prevention strategies which included the ED as a recruitment site in order to compare our recruitment productivity. RESULTS: In response to identified barriers, an enhanced ED-centered recruitment strategy was developed to address low recruitment rate, specifically (i) engaging a wider network of ED and outpatient psychiatry staff (ii) dissemination of study pamphlets across multiple areas of the ED and relevant outpatient clinics. Following implementation of the enhanced recruitment strategy, the pre-post recruitment productivity, a ratio of patients screened to patients randomized, was computed. A total of 120 patients were approached for participation, 89 (74.2%) were screened and 45 (37.5%) were consented for the study from March 2018 to April 2019. The screening to randomization ratio for the study period prior to the introduction of the enhanced recruitment strategies was 3:1, which decreased to 1.8:1 following the implementation of enhanced recruitment strategies. The ratio for the total recruitment period was 2.1:1. This was lower than the average ratio of 3.2:1 for published trials. CONCLUSIONS: EDs are feasible sites for participant recruitment in RCTs examining new interventions for acute mental health problems, including suicidality. Engaging multi-disciplinary ED staff to support recruitment for such studies, proactively addressing anticipated concerns, and creating a robust recruitment pathway that includes approach at outpatient appointments can optimize recruitment.

Cow's Milk Fat Obesity pRevention Trial (CoMFORT): a primary care embedded randomised controlled trial protocol to determine the effect of cow's milk fat on child adiposity.

INTRODUCTION: Cow's milk is a dietary staple for children in North America. Though clinical guidelines suggest children transition from whole (3.25% fat) milk to reduced (1% or 2%) fat milk at age 2 years, recent epidemiological evidence supports a link between whole milk consumption and lower adiposity in children. The purpose of this trial is to determine which milk fat recommendation minimises excess adiposity and optimises child nutrition and growth. METHODS AND ANALYSIS: Cow's Milk Fat Obesity pRevention Trial will be a pragmatic, superiority, parallel group randomised controlled trial involving children receiving routine healthcare aged 2 to 4-5 years who are participating in the TARGet Kids! practice-based research network in Toronto, Canada. Children (n=534) will be randomised to receive one of two interventions: (1) a recommendation to consume whole milk or (2) a recommendation to consume reduced (1%) fat milk. The primary outcome is adiposity measured by body mass index z-score and waist circumference z-score; secondary outcomes will be cognitive development (using the Ages and Stages Questionnaire), vitamin D stores, cardiometabolic health (glucose, high-sensitivity C-reactive protein, non-high density lipoprotein (non-HDL), low density lipoprotein (LDL), triglyceride, HDL and total cholesterol, insulin and diastolic and systolic blood pressure), sugary beverage and total energy intake (measured by 24 hours dietary recall) and cost effectiveness. Outcomes will be measured 24 months postrandomisation and compared using analysis of covariance (ANCOVA), adjusting for baseline measures. ETHICS AND DISSEMINATION: Ethics approval has been obtained from Unity Health Toronto and The Hospital for Sick Children. Results will be presented locally, nationally and internationally and published in a peer-reviewed journal. The findings may be helpful to nutrition guidelines for children in effort to reduce childhood obesity using a simple, inexpensive and scalable cow's milk fat intervention.
