Initiation of interdisciplinary prevention rounds: decreasing CLABSIs in critically ill children.

Objective: Central line-associated bloodstream infections (CLABSIs) harm children. Insertion and maintenance bundles have significantly reduced CLABSIs, but infections still occur. The objective was to develop bedside infection prevention (IP) rounds and evaluate their impact on CLABSI rates. Methods: This quality improvement project was initiated sequentially in the neonatal intensive care unit (NICU) and pediatric intensive care unit (PICU) of a large academic children's hospital. IP rounds, interdisciplinary discussions led by the hospital epidemiologist and unit nursing leader with the bedside nurse, occurred weekly for patients with central lines. Discussions included strategies to optimize line maintenance and identify and mitigate patient-specific infection risks. Concerns and recommendations were communicated with the clinician. CLABSIs were identified by prospective surveillance using standard definitions. The change in CLABSIs over time was analyzed using days-between-events charts (g chart). Results: IP rounds included 3,832 patients in the NICU and 1,322 patients in the PICU. Opportunities were identified to reduce line access and protect the dressing from contamination. The average days between CLABSIs in the NICU increased from 41 days to 54 days after IP rounds began. The longest time between CLABSIs was 362 days. In the PICU, the average days between CLABSIs increased from 53 to 91 days. The longest time between CLABSIs was 398 days. Conclusion: IP rounds reduced CLABSIs in the NICU and PICU by reinforcing best practices, encouraging proactive strategies, and fostering communication between members of the healthcare team.

Pediatric research priorities in healthcare-associated infections and antimicrobial stewardship.

OBJECTIVE: To develop a pediatric research agenda focused on pediatric healthcare-associated infections and antimicrobial stewardship topics that will yield the highest impact on child health. PARTICIPANTS: The study included 26 geographically diverse adult and pediatric infectious diseases clinicians with expertise in healthcare-associated infection prevention and/or antimicrobial stewardship (topic identification and ranking of priorities), as well as members of the Division of Healthcare Quality and Promotion at the Centers for Disease Control and Prevention (topic identification). METHODS: Using a modified Delphi approach, expert recommendations were generated through an iterative process for identifying pediatric research priorities in healthcare associated infection prevention and antimicrobial stewardship. The multistep, 7-month process included a literature review, interactive teleconferences, web-based surveys, and 2 in-person meetings. RESULTS: A final list of 12 high-priority research topics were generated in the 2 domains. High-priority healthcare-associated infection topics included judicious testing for Clostridioides difficile infection, chlorhexidine (CHG) bathing, measuring and preventing hospital-onset bloodstream infection rates, surgical site infection prevention, surveillance and prevention of multidrug resistant gram-negative rod infections. Antimicrobial stewardship topics included ß-lactam allergy de-labeling, judicious use of perioperative antibiotics, intravenous to oral conversion of antimicrobial therapy, developing a patient-level "harm index" for antibiotic exposure, and benchmarking and or peer comparison of antibiotic use for common inpatient conditions. CONCLUSIONS: We identified 6 healthcare-associated infection topics and 6 antimicrobial stewardship topics as potentially high-impact targets for pediatric research.

Comparison of Upper Respiratory Viral Load Distributions in Asymptomatic and Symptomatic Children Diagnosed with SARS-CoV-2 Infection in Pediatric Hospital Testing Programs.

The distribution of upper respiratory viral loads (VL) in asymptomatic children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unknown. We assessed PCR cycle threshold (Ct) values and estimated VL in infected asymptomatic children diagnosed in nine pediatric hospital testing programs. Records for asymptomatic and symptomatic patients with positive clinical SARS-CoV-2 tests were reviewed. Ct values were (i) adjusted by centering each value around the institutional median Ct value from symptomatic children tested with that assay and (ii) converted to estimated VL (numbers of copies per milliliter) using internal or manufacturer data. Adjusted Ct values and estimated VL for asymptomatic versus symptomatic children (118 asymptomatic versus 197 symptomatic children aged 0 to 4 years, 79 asymptomatic versus 97 symptomatic children aged 5 to 9 years, 69 asymptomatic versus 75 symptomatic children aged 10 to 13 years, 73 asymptomatic versus 109 symptomatic children aged 14 to 17 years) were compared. The median adjusted Ct value for asymptomatic children was 10.3 cycles higher than for symptomatic children (P < 0.0001), and VL were 3 to 4 logs lower than for symptomatic children (P < 0.0001); differences were consistent (P < 0.0001) across all four age brackets. These differences were consistent across all institutions and by sex, ethnicity, and race. Asymptomatic children with diabetes (odds ratio [OR], 6.5; P = 0.01), a recent contact (OR, 2.3; P = 0.02), and testing for surveillance (OR, 2.7; P = 0.005) had higher estimated risks of having a Ct value in the lowest quartile than children without, while an immunocompromised status had no effect. Children with asymptomatic SARS-CoV-2 infection had lower levels of virus in their nasopharynx/oropharynx than symptomatic children, but the timing of infection relative to diagnosis likely impacted levels in asymptomatic children. Caution is recommended when choosing diagnostic tests for screening of asymptomatic children.
