Association of empiric antibiotic selection and clinical outcomes in hospitalised children with severe orbital infections: a retrospective cohort study. Arch Dis Child 2024:archdischild-2023-326175. [PMID: 38589203 DOI: 10.1136/archdischild-2023-326175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Accepted: 03/27/2024] [Indexed: 04/10/2024]
Abstract
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.

Abstract
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.

De-implementing low-value continuous pulse oximetry practice in infants hospitalized with bronchiolitis: A multicentre qualitative study. J Hosp Med 2023; 18:1092-1101. [PMID: 37932871 DOI: 10.1002/jhm.13236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 10/07/2023] [Accepted: 10/19/2023] [Indexed: 11/08/2023]
Abstract
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.

Abstract
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. Int J Pediatr Otorhinolaryngol 2023; 171:111629. [PMID: 37437497 DOI: 10.1016/j.ijporl.2023.111629] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 06/04/2023] [Accepted: 06/07/2023] [Indexed: 07/14/2023]
Abstract
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.

Abstract
OBJECTIVES No previous study has examined the management of hospitalized children with orbital cellulitis at both children's and community hospitals across multiple sites in Canada. We describe variation and trends over time in diagnostic testing and imaging, adjunctive agents, empiric antibiotics, and surgical intervention in children hospitalized with orbital cellulitis. PATIENTS AND METHODS Multicenter cohort study of 1579 children aged 2 months to 18 years with orbital cellulitis infections admitted to 10 hospitals from 2009 to 2018. We assessed hospital-level variation in the use of diagnostic tests, imaging, antibiotics, adjunctive agents, surgical intervention, and clinical outcomes using X2, Mann-Whitney U, and Kruskal-Wallis tests. The association between clinical management and length of stay was evaluated with median regression analysis with hospital as a fixed effect. RESULTS There were significant differences between children's hospitals in usage of C-reactive protein tests (P < .001), computed tomography scans (P = .004), MRI scans (P = .003), intranasal decongestants (P < .001), intranasal corticosteroids (P < .001), intranasal saline spray (P < .001), and systemic corticosteroids (P < .001). Children's hospital patients had significantly longer length of hospital stay compared with community hospitals (P = .001). After adjustment, diagnostic testing, imaging, and subspecialty consults were associated with longer median length of hospital stay at children's hospitals. From 2009 to 2018, C-reactive protein test usage increased from 28.8% to 73.5% (P < .001), whereas erythrocyte sedimentation rate decreased from 31.5% to 14.1% (P < .001). CONCLUSIONS There was significant variation in diagnostic test usage and treatments, and increases in test usage and medical intervention rates over time despite minimal changes in surgical interventions and length of stay.

Abstract
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.

Canadian infants presenting with Brief Resolved Unexplained Events (BRUEs) and validation of clinical prediction rules for risk stratification: a protocol for a multicentre, retrospective cohort study. BMJ Open 2022; 12:e063183. [PMID: 36283756 PMCID: PMC9608523 DOI: 10.1136/bmjopen-2022-063183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/12/2022] Open
Abstract
INTRODUCTION Brief Resolved Unexplained Events (BRUEs) are a common presentation among infants. While most of these events are benign and self-limited, guidelines published by the American Academy of Pediatrics inaccurately identify many patients as higher-risk of a serious underlying aetiology (positive predictive value 5%). Recently, new clinical prediction rules have been derived to more accurately stratify patients. This data were however geographically limited to the USA, with no large studies to date assessing the BRUE population in a different healthcare setting. The study's aim is to describe the clinical management and outcomes of infants presenting to Canadian hospitals with BRUEs and to externally validate the BRUE clinical prediction rules in identified cases. METHODS AND ANALYSIS This is a multicentre retrospective study, conducted within the Canadian Paediatric Inpatient Research Network (PIRN). Infants (<1 year) presenting with a BRUE at one of 11 Canadian paediatric centres between 1 January 2017 and 31 December 2021 will be included. Eligible patients will be identified using diagnostic codes.The primary outcome will be the presence of a serious underlying illness. Secondary outcomes will include BRUE recurrence and length of hospital stay. We will describe the rates of hospital admissions and whether hospitalisation was associated with an earlier diagnosis or treatment. Variation across Canadian hospitals will be assessed using intraclass correlation coefficient. To validate the newly developed clinical prediction rule, measures of goodness of fit will be evaluated. For this validation, a sample size of 1182 is required to provide a power of 80% to detect patients with a serious underlying illness with a significance level of 5%. ETHICS AND DISSEMINATION Ethics approval has been granted by the UBC Children's and Women's Research Board (H21-02357). The results of this study will be disseminated as peer-reviewed manuscripts and presentations at national and international conferences.

Abstract
Abstract
Background
Pulse oximetry is a non-invasive technology that is integral to the supportive care of hospitalized infants with bronchiolitis. A multi-centre, randomized trial comparing the effectiveness of intermittent vs. continuous pulse oximetry found similar hospital length of 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/Methods
Prospective economic evaluation concurrent with a randomized trial (October 2016 to May 2019) using a probabilistic analysis. Infants (n=229) 4 weeks to 24 months hospitalized with bronchiolitis, with or without supplemental oxygen, after stabilization were randomized at six Ontario hospitals (community and children's) to intermittent (every 4 hours) vs. continuous pulse oximetry using an oxygen saturation target of 90% or higher. The main outcome measure for the economic evaluation was cost and incremental costs. The clinical effect measure was length of hospital stay in hours. The cost-effective 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. Costs, health resource use 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 2020 Canadian dollars. This study was funded by a grant from the Canadian Institutes of Health Research.
Results
Trial data from 229 infants across six hospitals was included. Mean societal costs per patient were lower in the intermittent monitoring group: $6528 (95% CI: $3201, $12058) in the intermittent and $6815 (95% CI: $1454, $26485) in the continuous group with a mean incremental cost of -$287 (95% CI -$20084, $7842). Mean health care system costs per patient were $3992 (95% CI -$1139, $9224) in the intermittent and $4604 (95% CI -$317, $24126) in the continuous group (incremental cost -$613 (95% CI -$20564, $7089). The mean effect measure, length of stay, was also similar between the two groups: 36.3 hours in the intermittent group and 40.2 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.
Conclusion
In a prospective economic evaluation conducted with a clinical trial, we found that intermittent monitoring was less expensive than continuous monitoring, considering societal and health care costs. These findings support recommendations to use intermittent pulse oximetry monitoring in hospitalized infants with stabilized bronchiolitis.

Abstract
Abstract
Background
Bronchiolitis is the most common reason for hospitalization in infants and is cumulatively costly for the healthcare system. Trial evidence and national guidelines support the routine use of intermittent pulse oximetry in stabilized (no oxygen supplementation) infants with bronchiolitis. However, continuous pulse oximetry use is common.
Objectives
To understand the barriers and facilitators important to de-implementing continuous pulse oximetry and implementing intermittent pulse oximetry in stabilized infants hospitalized with bronchiolitis.
Design/Methods
From December 2018 to January 2020, participants were recruited from six Ontario hospitals (3 community and 3 paediatric hospitals) in a multi-centre qualitative study. Focus groups were conducted with staff paediatricians, paediatric residents, nurses, and respiratory therapists. Interviews were conducted with caregivers of infants recently hospitalized with bronchiolitis. Participants' beliefs, attitudes, and experiences related to pulse oximetry use in bronchiolitis management were explored. Recordings were transcribed and analyzed using thematic analysis via NVivo software to understand barriers and facilitators to practice change. These were then mapped to the domains and the constructs of the Consolidated Framework for Implementation Research (CFIR).
Results
67 individuals from six hospitals participated. Themes relevant to understanding barriers and facilitators to de-implementing continuous and implementing intermittent monitoring were identified. Healthcare professionals emphasized the importance of identifying and understanding who is responsible for bedside monitoring practice (physician vs. nurses). Clinical experience, knowledge of guidelines (international and local practice), importance relative to competing priorities, and the tensions amongst team members due to practice variation all influenced monitoring practice. Nurses held beliefs around the advantages of intermittent monitoring (e.g., reduced alarm fatigue, facilitation of timely discharges and reduced workload). Clinicians identified ways to clarify indications for ongoing continuous monitoring (e.g., based on clinical risk factors such as medical complexity, prematurity, and age), vs. indications to transition to intermittent monitoring (e.g., established oral feeding, sleeping without desaturations, and off supplemental oxygen). Caregivers did not express a clear preference for monitoring type, but described the stress of having a child admitted to hospital with an emphasis on the need for clear communication around the interpretation of monitors, management decisions, and care transitions.
Conclusion
In this multi-centre qualitative study of clinicians and caregivers, we identified barriers and facilitators that are important to de-implementing continuous monitoring and implementing intermittent monitoring. Understanding professional roles, clarity around local practice standards and supporting families' understanding of pulse oximetry monitoring practices are essential for practice change.

Abstract
OBJECTIVES To evaluate risk factors associated with surgical intervention and subperiosteal/orbital abscess in hospitalized children with severe orbital infections. STUDY DESIGN We conducted a multicenter cohort study of children 2 months to 18 years hospitalized with periorbital or orbital cellulitis from 2009 to 2018 at 10 hospitals in Canada. Clinical details were extracted, and patients were categorized as undergoing surgical or medical-only management. Primary outcome was surgical intervention and the main secondary outcome was clinically important imaging. Logistic regression was used to identify predictors. RESULTS Of 1579 patients entered, median age was 5.4 years, 409 (25.9%) had an orbital/subperiosteal abscess, and 189 (12.0%) underwent surgery. In the adjusted analysis, the risk of surgical intervention was associated with older age (age 9 to <14: aOR 3.9, 95% CI 2.3-6.6; and age 14 to ≤18 years: aOR 7.0, 95% CI 3.4-14.1), elevated C-reactive protein >120 mg/L (aOR 2.8, 95% CI 1.3-5.9), elevated white blood cell count of 12-20 000/μL (aOR 1.7, 95% CI 1.1-2.6), proptosis (aOR 2.6, 95% CI 1.7-4.0), and subperiosteal/orbital abscess (aOR 5.3, 95% CI 3.6-7.9). There was no association with antibiotic use before hospital admission, sex, presence of a chronic disease, temperature greater than 38.0°C, and eye swollen shut. Complications were identified in 4.7% of patients, including vision loss (0.6%), intracranial extension (1.6%), and meningitis (0.8%). CONCLUSIONS In children hospitalized with severe orbital infections, older age, elevated C-reactive protein, elevated white blood cell count, proptosis, and subperiosteal/orbital abscess were predictors of surgical intervention.

Abstract
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.

Bladder and Bowel Dysfunction Network: Improving the Management of Pediatric Bladder and Bowel Dysfunction. Pediatr Qual Saf 2021; 6:e383. [PMID: 33718744 PMCID: PMC7952106 DOI: 10.1097/pq9.0000000000000383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Accepted: 09/15/2020] [Indexed: 11/26/2022] Open
Abstract
Lower urinary tract symptoms with constipation characterize bladder and bowel dysfunction (BBD). Due to high referral volumes to hospital pediatric urology clinics and time-consuming appointments, wait times are prolonged. Initial management consists of behavioral modification strategies that could be accomplished by community pediatricians. We aimed to create a network of community pediatricians trained in BBD (BBDN) management and assess its impact on care. METHODS We distributed a survey to pediatricians, and those interested attended training consisting of lectures and clinical shadowing. Patients referred to a hospital pediatric urology clinic were triaged to the BBDN and completed the dysfunctional voiding symptom score and satisfaction surveys at baseline and follow-up. The Bristol stool chart was used to assess constipation. Results were compared between BBDN and hospital clinic patients. RESULTS Surveyed pediatricians (n = 100) most commonly managed BBD with PEG3350 and dietary changes and were less likely to recommend bladder retraining strategies. Baseline characteristics were similar in BBDN (n = 100) and hospital clinic patients (n = 23). Both groups had similar improvements in dysfunctional voiding symptom score from baseline to follow-up (10.1 ± 4.2 to 5.6 ± 3.3, P = 0.01, versus 10.1 ± 4.2 to 7.8 ± 4.5, P = 0.02). BBDN patients waited less time for their follow-up visit with 56 (28-70) days versus 94.5 (85-109) days for hospital clinic patients (P < 0.001). Both groups demonstrated high familial satisfaction. CONCLUSIONS Community pediatricians may require more knowledge of management strategies for BBD. Our pilot study demonstrates that implementing a BBDN is feasible, results in shorter wait times, and similar improvement in symptoms and patient satisfaction than a hospital pediatric urology clinic.

Abstract
INTRODUCTION Skin and soft tissue infections of the eye can be classified based on anatomic location as either anterior to the orbital septum (ie, periorbital cellulitis) or posterior to the orbital septum (ie, orbital cellulitis). These two conditions are often considered together in hospitalised children as clinical differentiation is difficult, especially in young children. Prior studies have identified variation in management of hospitalised children with orbital cellulitis; however, they have been limited either as single centre studies or by the use of administrative data which lacks clinical details important for interpreting variation in care. We aim to describe the care and outcomes of Canadian children hospitalised with periorbital and orbital cellulitis. METHOD AND ANALYSIS This is a multisite retrospective cohort study including previously healthy children aged 2 months to 18 years admitted to hospital with periorbital or orbital cellulitis from 2009 to 2018. Clinical data from medical records from multiple Canadian hospitals will be collected, including community and academic centres. Demographic characteristics and study outcomes will be summarised using descriptive statistics, including diagnostic testing, antibiotic therapy, adjunctive therapy, surgical intervention and clinical outcomes. Variation will be described and evaluated using χ² test or Kruskal-Wallis test. Generalised linear mixed models will be used to identify predictors of surgical intervention and longer length of stay. ETHICS AND DISSEMINATION Approval of the study by the Research Ethics Board at each participating site has been obtained prior to data extraction. Study results will be disseminated by presentations at national and international meetings and by publications in high impact open access journals. By identifying important differences in management and outcomes by each hospital, the results will identify areas where care can be improved, practice standardised, unnecessary diagnostic imaging reduced, pharmacotherapy rationalised and where trials are needed.

Abstract
INTRODUCTION Technological and medical advances have led to a growing population of children with medical complexity (CMC) defined by substantial medical needs, healthcare utilisation and morbidity. These children are at a high risk of missed, fragmented and/or inappropriate care, and families bear extraordinary financial burden and stress. While small in number (<1% of children), this group uses ~1/3 of all child healthcare resources, and need coordinated care to optimise their health. Complex care for kids Ontario (CCKO) brings researchers, families and healthcare providers together to develop, implement and evaluate a population-level roll-out of care for CMC in Ontario, Canada through a randomised controlled trial (RCT) design. The intervention includes dedicated key workers and the utilisation of coordinated shared care plans. METHODS AND ANALYSIS Our primary objective is to evaluate the CCKO intervention using a randomised waitlist control design. The waitlist approach involves rolling out an intervention over time, whereby all participants are randomised into two groups (A and B) to receive the intervention at different time points determined at random. Baseline measurements are collected at month 0, and groups A and B are compared at months 6 and 12. The primary outcome is the family-prioritized Family Experiences with Coordination of Care (FECC) survey at 12 months. The FECC will be compared between groups using an analysis of covariance with the corresponding baseline score as the covariate. Secondary outcomes include reports of child and parent health outcomes, health system utilisation and process outcomes. ETHICS AND DISSEMINATION Research ethics approval has been obtained for this multicentre RCT. This trial will assess the effect of a large population-level complex care intervention to determine whether dedicated key workers and coordinated care plans have an impact on improving service delivery and quality of life for CMC and their families. TRIAL REGISTRATION NUMBER NCT02928757.

Abstract
INTRODUCTION The support of families in the care of children with medical complexity (CMC) requires the integration of health care providers' (HCPs') medical knowledge and family experience. Care plans largely represent HCP information, and care maps demonstrate the family experience. Understanding the intersection between a care plan and a care map is critical, as it may provide solutions to the widely recognized tension between HCP-directed care and patient- and family-centered care (PFCC). METHOD This study used qualitative methods to explore the experience and usefulness of care maps. Parents of CMC who already had a care plan, created care maps (n = 15). Subsequent interviews with parents (n = 15) and HCPs (n = 30) of CMC regarding both care maps and care plans were conducted and analyzed using thematic analysis. RESULTS Data analysis exploring the relationship and utility of care plans and care maps revealed six primary themes related to using care plans and care maps that were grouped into two primary categories: (a) utility of care plans and maps; and (b) intersection of care plans and care maps. DISCUSSION Care plans and care maps were identified as valuable complementary documents. Their integration offers context about family experience and respects the parents' experiential wisdom in a standard patient care document, thus promoting improved understanding and integration of the family experience into care decision making.

DEVELOPMENT OF A STANDARDIZED APPROACH FOR THE ASSESSMENT OF BOWEL AND BLADDER DYSFUNCTION IN COMMUNITY PAEDIATRICS. Paediatr Child Health 2018.

Abstract
Abstract
BACKGROUND
Bowel and bladder dysfunction (BBD) is a common yet underdiagnosed paediatric condition that describes a constellation of lower urinary tract symptoms (LUTS) associated with constipation and/or encopresis. Many children with BBD have co-morbid neuropsychiatric symptoms (e.g., inattention, anxiety) and psychosocial stressors. Thus, clinical assessment of behavioural symptoms and social risk factors in this population is essential. However, there is no standardized approach for a comprehensive assessment of BBD.
OBJECTIVES
We aim to develop and evaluate physician and parent perceptions with 1) a standardized BBD history and physical intake form for physicians, and 2) a parent-reported intake form.
DESIGN/METHODS
From June to Oct 2017, a quality improvement study was conducted in the BBD network, an existing paediatric collaborative initiative consisting of 7 community sites with support of the paediatric urology division in a tertiary hospital. Based on literature review and expert opinions, a standardized intake form was developed for BBD assessment with targeted questions for LUTS, constipation, behavioural, dietary, and psychosocial history, along with a physical exam checklist for neurological red flags. Further, a shorter parent-reported intake questionnaire was developed to clarify patterns of dysfunctional voiding symptoms, dietary recall and stool history. Both forms underwent usability testing and iterative refinement. Prior to clinic, families of children referred for BBD were mailed an intake package for completion. During the clinic, physicians were asked to use the standardized intake form for new referrals. Afterwards, both physicians and parents were given anonymous surveys to evaluate their perceptions of the intake process.
RESULTS
A total of 8 physicians and 20 parents responded, with 60% of patients being between ages 4–10 and 55% male. Physicians found the standardized intake form to be a useful guide that reminded them to ask about specific urinary symptoms (88% of the time), constipation (75%), and psychosocial history (76%). The majority of physicians (75%) agreed they would use the intake form again and recommended its implementation. Further, parents responded positively by agreeing that the intake package was easy to complete (65%), felt included in care decisions (95%), and had questions answered appropriately (100%).
CONCLUSION
In assessment of BBD, a standardized intake form can help guide physicians to efficiently gather a comprehensive history, rule out red flags, and screen for psychosocial risk factors. With refinements, it can potentially help create a common clinical experience and empower more community paediatricians to manage BBD in the future.

Abstract
INTRODUCTION Bronchiolitis is the most common reason for hospitalisation in infants in developed countries. The main focus of hospital care is on supportive care, such as monitoring for hypoxia and supplemental oxygen administration, as active therapies lack effectiveness. Pulse oximetry is used to monitor hypoxia in hospitalised infants and is used either intermittently or continuously. Observational studies have suggested that continuous pulse oximetry use leads to a longer length of hospital stay in stable infants. The use of continuous pulse oximetry may lead to unnecessary clinical intervention due to readings that are of little clinical significance, false-positive readings and less reliance on the clinical status. There is a lack of high-quality evidence to guide which pulse oximetry monitoring strategy, intermittent or continuous, is superior in infants hospitalised with bronchiolitis with respect to patient and policy-relevant outcomes. METHODS AND ANALYSIS This is a multicentre, pragmatic randomised controlled trial comparing two strategies for pulse oximetry monitoring in infants hospitalised for bronchiolitis. Infants aged 1 month to 2 years presenting to Canadian tertiary and community hospitals will be randomised after stabilisation to receive either intermittent or continuous oxygen saturation monitoring on the inpatient unit until discharge. The primary outcome is length of hospital stay. Secondary outcomes include additional measures of effectiveness, acceptability, safety and cost. We will need to enrol 210 infants in order to detect a 12-hour difference in length of stay with a type 1 error rate of 5% and a power of 90%. ETHICS AND DISSEMINATION Research ethics approval has been obtained for this trial. This trial will provide data to guide hospitals and clinicians on the optimal pulse oximetry monitoring strategy in infants hospitalised with bronchiolitis. We will disseminate the findings of this study through peer-reviewed publication, professional societies and meetings. TRIAL REGISTRATION NUMBER NCT02947204.

Abstract
AIM Children with medical complexity require multiple providers and services to keep them well and at home. A care map is a patient/family-created diagram that pictorially maps out this complex web of services. This study explored what care maps mean for families and healthcare providers to inform potential for clinical use. METHOD Parents (n=15) created care maps (hand drawn n=10 and computer-generated n=5) and participated in semi-structured interviews about the process of developing care maps and their perceived impact. Healthcare providers (n=30) reviewed the parent-created care maps and participated in semi-structured interviews. Data were analysed for themes and emerging theory using a grounded theory analytical approach. RESULTS Data analysis revealed 13 overarching themes that were further categorized into three domains: features (characteristics of care maps), functions (what care maps do), and emerging outcomes (benefits of care map use). These domains further informed a definition and a theoretical model of how care maps work. INTERPRETATION Our findings suggest that care maps may be a way of supporting patient- and family-centred care by graphically identifying and integrating experiences of the family as well as priorities for moving forward. WHAT THIS PAPER ADDS Care maps were endorsed as a useful tool by families and providers. They help healthcare providers better understand parental priorities for care. Parents can create care maps to demonstrate the complex burden of care. They are a unique visual way to incorporate narrative medicine into practice.

Abstract
Abstract
BACKGROUND: A care map is a visual diagram that illustrates all of the resources needed to support a child with medical complexity, providing a contextualized view of the child in a broader health network. It is believed that health care providers (HCPs) can utilize care maps to enable child and family centered care by helping families prioritize and coordinate their health needs. While the popularity of care maps has been growing, there is a paucity of research on their clinical usefulness.
OBJECTIVES: The objective of this study is to explore how care maps are constructed by parents, what they mean for parents and HCPs, and how they can be applied in a clinical setting.
DESIGN/METHODS: This is a qualitative study informed by a grounded theory approach. Theoretical sampling of parents and HCPs of CMC was utilized. Fifteen care map training sessions and forty-five semi-structured interviews with parents and HCPs of CMC were conducted. The data was coded and analyzed iteratively for predominant themes and emerging theory.
RESULTS: Both HCPs and parents strongly identified the care map [Figure 1] as a valuable tool in the care of CMC. Data analysis revealed key themes that demonstrated how and why care maps are useful. Care maps allow HCPs to recognize family experiences, identify parental goals of care and promote improved care coordination and communication. Parents described creating care maps as an empowering and therapeutic process that helped them to organize and communicate their complex interplay of supports. Both parents and HCPs acknowledged challenges associated with care mapping including the ability of parents to create a care map as well as the HCPs ability to independently interpret the care map’s meaning.
CONCLUSION: Care maps are a useful communication and coordination tool to demonstrate a contextualized view of a family’s narrative of their experience caring for a CMC. Findings may inform a model of how to utilize care maps in clinical practice.

Abstract
Background Data linkage studies find that depression before or after a breast cancer diagnosis predicts reduced survival. This study aimed to determine whether depression or bipolar recorded in routine hospital admission data independently predicts survival in English breast cancer patients and whether onset in relation to cancer diagnosis is significant. Methods Data on 77 173 women diagnosed with breast cancer (ICD‐10 C50) in South East England, 2000–2009, were included. Of these, 131 women had a diagnosis of bipolar affective disorder (ICD‐10 F31) and 955 of depression (either depressive episodes (ICD‐10 F32) or depressive disorder (ICD‐10 F33)) recorded in Hospital Episode Statistics between 3 years before and a year following cancer diagnosis. Kaplan–Meier plots were used to examine overall survival. Cox regression analyses were carried out overall and separately for mood disorder diagnoses before and after the cancer diagnosis and adjusted for confounding variables. Results A record of depression was a predictor of worse overall survival in breast cancer patients (adjusted HR = 1.33, 95% CI: 1.20–1.48, p < 0.001), while the effect of bipolar was not statistically significant (adjusted HR = 1.33, 95% CI: 0.97–1.82, p = 0.079). New recordings of depression and bipolar diagnoses following a cancer diagnosis appeared better predictors of overall survival than a prior history of either. Conclusions There is evidence that English breast cancer patients with depression and bipolar recorded in routine hospital data have worse overall survival than those without these mood disorders. Further work exploring the concordance of records within administrative health data with clinical diagnosis and cause‐specific death within these patient groups is needed. © 2015 The Authors.

Abstract
Leptin, the product of the obesity (ob) gene, controls energy intake and expenditure primarily by actions on the central nervous system. However, recently it has become apparent that leptin also elicits a growing and diverse array of effects on peripheral tissues. The Na,K-pump is an electrogenic plasma membrane protein which actively extrudes 3Na+ ions and imports 2K+ ions per molecule of ATP hydrolysed. The pump is responsible for the maintenance of the electrochemical potential of all cells, which in turn drives all ion-coupled transport mechanisms. In this study we use 3T3-L1 fibroblasts to show that leptin inhibits Na,K-pump activity, as assessed by ouabain-sensitive 86Rb+ uptake. Inhibition of the Na,K-pump correlated with increased serine phosphorylation of the catalytic Na,K-pump alpha1 subunit. Upon investigation of leptin-stimulated signalling pathways using specific pharmacological inhibitors, only wortmannin prevented inhibition of the Na,K-pump by leptin. Moreover, leptin stimulated phosphotyrosine-associated PI 3-kinase activity in these cells. In summary, leptin was found to inhibit Na,K-pump activity, likely via PI 3-kinase. We propose that this effect may have wide ranging cardiovascular and metabolic implications and perhaps explain physiological effects of the hormone such as natriuresis.

Abstract
BACKGROUND Low adherence of patients to prescribed, self-administered medical interventions is ubiquitous. Low adherence limits the benefits of current medical care. Efforts to assist patients to follow treatments might improve the efficiency of care and substantially enhance benefits. Our objective was to summarise the results of randomised controlled trials (RCTs) of interventions to help patients follow prescriptions for medications. METHODS A previous systematic review was updated through computerised searches in Medline, International Pharmaceutical Abstracts, Psychinfo, and HSTAR online databases; bibliographies in articles on patient adherence; articles in the reviewers' personal collections; and contact with authors. Articles were judged of interest if they reported original data concerning an unconfounded RCT of an intervention to improve adherence with prescribed medications, with one or more measure of medication adherence, one or more measure of treatment outcome, at least 80% follow-up of each group studied, and, for long-term treatments, at least 6 months of follow-up for studies with positive initial findings. Information on study design features, interventions and controls, and findings were extracted by one reviewer (RK) and checked by the other two reviewers. FINDINGS 1,553 relevant citations and abstracts were screened, 252 full text articles were reviewed in detail, and 13 RCTs met all criteria. The studies were too disparate in clinical problems, adherence interventions, measures and reporting of adherence, and the clinical outcomes studied to warrant meta-analysis. Seven of 15 interventions were associated with improvements in adherence and six interventions led to improvements in treatment outcomes. For short-term treatments, one study showed an effect on adherence and outcome of counselling and written information. The interventions that were effective for long-term care were complex, including various combinations of more convenient care, information, counselling, reminders, self-monitoring, reinforcement, family therapy, and other forms of additional supervision or attention. Even the most effective interventions did not lead to substantial improvements in adherence. INTERPRETATION Although adherence and treatment outcomes can be improved by certain-usually complex-interventions, full benefits of medications cannot be realised at currently achievable levels of adherence. It is time that additional efforts be directed towards developing and testing innovative approaches to assist patients to follow treatment prescriptions.
