Structural equation modeling to evaluate the adult vaccine hesitancy scale for vaccines recommended during pregnancy.

Introduction: Acceptance of recommended vaccines is lower among pregnant people compared to non-pregnant adults, yet no tool has specifically measured prenatal vaccine hesitancy. We evaluated the performance of an existing adult Vaccine Hesitancy Scale (aVHS) in measuring vaccine hesitancy toward routinely recommended prenatal vaccines.

Methods: Between December 2021 and April 2022, we conducted a cross-sectional national online survey with 917 US postpartum adults 18-49 years old who had given birth in the past six months.

The adoption and compliance to central line-associated bloodstream infection insertion and maintenance bundle programs in intensive care unit settings across Canada.

Evidence-based insertion and maintenance bundles are effective in reducing the incidence of central line-associated bloodstream infections (CLABSI) in intensive care unit (ICU) settings. We studied the adoption and compliance of CLABSI prevention bundle programs and CLABSI rates in ICUs in a large network of acute care hospitals across Canada.

Enhancing HPV vaccine uptake in girls and boys - A qualitative analysis of Canadian school-based vaccination programs.

The purpose of this study was to better understand barriers and enabling conditions for HPV vaccination in school-based vaccination programs in Canada. Semi-structured interviews were conducted by telephone or in person with parents, nurses, and school staff (n = 50) in three Canadian provinces. Interviews explored views on HPV and HPV vaccination, strengths and weaknesses of the school-based HPV vaccination programs and proposed interventions to increase uptake.

Practice recommendations regarding parental presence in NICUs during pandemics caused by respiratory pathogens like COVID-19.

Aim: To co-create parental presence practice recommendations across Canadian NICUs during pandemics caused by respiratory pathogens such as COVID-19.

Methods: Recommendations were developed through evidence, context, Delphi and Values and Preferences methods. For Delphi 1 and 2, participants rated 50 items and 20 items respectively on a scale from 1 (very low importance) to 5 (very high).

Language: the ignored determinant of health.

Canada is one of the most multicultural countries in the world, with growing numbers of families who do not speak English or French as a first language. However, providing language-concordant services for patients with non-official language preference (NOLP) is not a standardized or measured component of our healthcare system, reflecting the historical marginalization of minority groups in our society. Existing evidence from other countries demonstrates the importance of language as a social determinant of health, and illustrates improved healthcare outcomes for patients with NOLP with the use of medical interpretation.

Retrospective validation of a rapid Lyme fluorescent immunoassay in differentiating Lyme arthritis from other musculoskeletal presentations in children in a Lyme-endemic region.

Unlabelled: Lyme arthritis can present similarly to other causes of joint pain and swelling including septic arthritis and other acute and chronic arthropathies of childhood. Septic arthritis, although rare, constitutes an orthopedic emergency and requires early surgical intervention to reduce the risk of permanent joint damage. Currently, results of standard serologic tests to diagnose Lyme disease take days to weeks, which is unhelpful in acute clinical decision-making.

A Pediatric Investigators Collaborative Network on Infections in Children (PICNIC) multi-centre Canadian descriptive analysis of bacteremia in children: Emerging serotypes.

Background: There has been dramatic reduction in serotype b (Hib) since introduction of Hib vaccines, but children still experience serious invasive (Hi) disease caused by various serotype and non-typeable bacteria. The object of this study was to describe the serotype distribution and clinical spectrum of Hi bacteremia in children admitted to Canadian hospitals.

Methods: All children with Hi bacteremia admitted 2013 through 2017 to 10 centres across Canada were included.

Nirmatrelvir-ritonavir use among adults hospitalized with COVID-19 during the Omicron phase of the COVID-19 pandemic, Canadian Nosocomial Infection Surveillance Program.

Background: Recent studies have demonstrated the effectiveness of nirmatrelvir-ritonavir in reducing the risk of progression to severe disease among outpatients with mild to moderate coronavirus disease 2019 (COVID-19); however, data are limited regarding the use and role of nirmatrelvir-ritonavir among hospitalized patients. This study describes the use and outcomes of nirmatrelvir-ritonavir among adults hospitalized with COVID-19 in a sentinel network of Canadian acute care hospitals during the Omicron variant phase of the pandemic.

Methods: The Canadian Nosocomial Infection Surveillance Program conducts surveillance of hospitalized patients with COVID-19 in acute care hospitals across Canada.

Effectiveness of face masks for reducing transmission of SARS-CoV-2: a rapid systematic review.

This rapid systematic review of evidence asks whether (i) wearing a face mask, (ii) one type of mask over another and (iii) mandatory mask policies can reduce the transmission of SARS-CoV-2 infection, either in community-based or healthcare settings. A search of studies published 1 January 2020-27 January 2023 yielded 5185 unique records. Due to a paucity of randomized controlled trials (RCTs), observational studies were included in the analysis.

Development of Quality Indicators to Evaluate the Appropriateness of Empiric Antimicrobial Use in Pediatric Patients.

Background: Use of quality indicators is one strategy recommended to assess antimicrobial prescribing for pediatric inpatients.

Objective: To achieve consensus from infectious diseases clinicians on quality indicators that characterize appropriate empiric antimicrobial use for the management of infectious syndromes in pediatric inpatients.

Methods: This study was completed using the Delphi technique.

Evaluating the impact of incorporating clinical practice guidelines for the management of infectious diseases into an electronic application (e-app).

Objectives: To improve dissemination and accessibility of guidelines to healthcare providers at our institution, guidance for infectious syndromes was incorporated into an electronic application (e-app). The objective of this study was to compare empiric antimicrobial prescribing before and after implementation of the e-app.

Design: This study was a before-and-after trial.

Vaccines, Politics and Mandates: Can We See the Forest for the Trees? Comment on "Convergence on Coercion: Functional and Political Pressures as Drivers of Global Childhood Vaccine Mandates".

Under-vaccination is a complex problem that is not simple to address whether this is for routine childhood immunization or for coronavirus disease 2019 (COVID-19) vaccination. Vaccination mandates has been one policy instrument used to try to increase vaccine uptake. While the concept may appear straight forward there is no standard approach.

Assessment of COVID-19 barrier effectiveness using process safety techniques.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes a respiratory illness called the novel coronavirus 2019 (COVID-19). COVID-19 was declared a pandemic on March 11, 2020. Bow tie analysis (BTA) was applied to analyze the hazard of SARS-CoV-2 for three receptor groups: patient or family member at the IWK Health Centre in acute care, staff member at a British Columbia Forest Safety Council (BCFSC) wood pellet facility, and staff member at the Suncor refinery in Sarnia, Ontario.

Cerebrospinal fluid shunt-associated surgical site infection with three-month versus twelve-month surveillance periods in Canadian hospitals.

Cerebrospinal fluid shunt-associated surgical site infection surveillance for 3 months compared to 12 months after surgery captures 83% of cases with no significant differences in patient characteristics, surgery types, or pathogens. A shorter 3-month follow-up can reduce resource use and allow for more timely reporting of healthcare-associated infection rates for hospitals.

Paediatric Investigators Collaborative Network on Infections in Canada (PICNIC) study of the current landscape of invasive meningococcal disease in children.

Background: Immunizations have led to a decrease in the incidence of invasive meningococcal disease (IMD) in Canada, but this infection still leads to significant morbidity and mortality.

Objectives: The purpose of this study was to determine the burden of illness and management of IMD in paediatric hospitals.

Methods: Data were collected on all cases of IMD in eight paediatric hospitals from 2013 to 2017.

A public health timeline to prepare for COVID-19 vaccines in Canada.

For control of COVID-19, community immunity is required, necessitating widespread immunization. COVID-19 vaccines are coming to Canada, with the government announcing in August 2020 agreements with four different companies for their COVID-19 vaccine if their trials are successful. Never before has public health had to rapidly develop a vaccine introduction program for multiple new but differing vaccines with the added pressure that the program is needed across all ages and in all Canadian communities and there is high probability of not enough vaccine to go around at the start.
