Resource stewardship and Choosing Wisely in a children's hospital.

Objectives: Evidence suggests that approximately 30% of the tests and treatments currently prescribed in healthcare are potentially unnecessary, may not add value, and in some cases cause harm. We describe the evolution of our hospital's Choosing Wisely (CW) program over the first 5 years of existence, highlighting the enablers, challenges, and overall lessons learned with the goal of informing other healthcare providers about implementing resource stewardship initiatives in paediatric healthcare settings.

Methods: We describe the development of de novo "top 5" CW lists of recommendations using anonymous surveys and Likert scale scoring.

Secondary impacts of the COVID-19 pandemic at a tertiary children's hospital in Canada: a mixed-methods study.

Objectives: Decisions to pause all non-essential paediatric hospital activities during the initial phase of the COVID-19 pandemic may have led to significant delays, deferrals and disruptions in medical care. This study explores clinical cases where the care of children was perceived by hospital clinicians to have been negatively impacted because of the changes in healthcare delivery attributing to the restrictions placed resulting from the COVID-19 pandemic.

Design And Setting: This study used a mixed-methods approach using the following: (1) a quantitative analysis of overall descriptive hospital activity between May and August 2020, and utilisation of data during the study period was performed, and (2) a qualitative multiple-case study design with descriptive thematic analysis of clinician-reported consequences of the COVID-19 pandemic on care provided at a tertiary children's hospital.

A Comparison of Short Versus Long Course Intravenous Antibiotics When Treating Urinary Tract Infection in Infants <60 Days of Age.

Urinary tract infections (UTIs) are a common reason for hospitalization in infants younger than 60 days, and the optimal approach to intravenous (IV) antibiotic therapy upon UTI diagnosis in this cohort is unknown. We determined whether there was an association between IV antibiotic therapy duration (long [>3 days] vs short [≤3 days]) and treatment failure via a retrospective review of infants with confirmed UTIs receiving IV antibiotics at a tertiary referral center. A total of 403 infants were included; 39% were treated with ampicillin and cefotaxime, and 34% with ampicillin and gentamycin or tobramycin.

Effect of Wearing a Face Mask on Hand-to-Face Contact by Children in a Simulated School Environment: The Back-to-School COVID-19 Simulation Randomized Clinical Trial.

Importance: Wearing a face mask in school can reduce SARS-CoV-2 transmission but it may also lead to increased hand-to-face contact, which in turn could increase infection risk through self-inoculation.

Objective: To evaluate the effect of wearing a face mask on hand-to-face contact by children while at school.

Design, Setting, And Participants: This prospective randomized clinical trial randomized students from junior kindergarten to grade 12 at 2 schools in Toronto, Ontario, Canada, during August 2020 in a 1:1 ratio to either a mask or control class during a 2-day school simulation.

Adverse Effects Associated with Patient-Controlled Analgesia with Ketamine Combined with Opioids and Ketamine Infusion with PCA Bolus in Postoperative Spine Patients: A Retrospective Review.

Objective: There has been increasing use of ketamine at subanesthetic doses as an adjunct to opioids in perioperative pain management. There are several known adverse drug effects (ADEs) associated with ketamine. However, the incidence of ADEs with ketamine infusions with patient-controlled analgesia (PCA) boluses compared with combined opioid and ketamine PCAs is not well described.

Variation in low-value radiograph use for children in the emergency department: a cross-sectional study of administrative databases.

Background: Radiograph use contributes to low-value care for children in emergency departments (EDs), but little is known about systemic factors associated with their use. This study compares low-value radiograph use across ED settings by hospital type, pediatric volumes and physician specialty.

Methods: This is a cross-sectional study of routinely collected administrative data.
