Abstract

OBJECTIVES: We evaluated the impact of a test-to-stay (TTS) program on within-school transmission and missed school days in optionally masked kindergarten through 12th grade schools during a period of high community severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission.

METHODS: Close contacts of those with confirmed SARS-CoV-2 infection were eligible for enrollment in the TTS program if exposure to a non-household contact occurred between 11/29/2021 and 01/28/2022. Consented participants avoided school exclusion if they remained asymptomatic and rapid antigen testing at pre-specified intervals remained negative. Primary outcomes included within-school tertiary attack rate (test positivity among close contacts of positive TTS participants) and school days saved among TTS participants. We estimated the number of additional school-acquired cases resulting from TTS and eliminating school exclusion.

RESULTS: A total of 1675 participants tested positive or received at least one negative test between days 5 and 7, and completed follow-up; 92% were students and 91% were exposed to an unmasked primary case. We identified 201 positive cases. We observed a tertiary attack rate of 10% (95% CI 6-19%) and 7,272 (89%) of potentially missed days were saved through TTS implementation. We estimated one additional school-acquired case for every 21 TTS participants remaining in school buildings during the entire study period.

CONCLUSIONS: Even in the setting of high community transmission, a TTS strategy resulted in substantial reduction in missed school days in optionally masked schools.

Abstract

<p><strong>OBJECTIVE: </strong>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.</p>

<p><strong>PARTICIPANTS: </strong>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).</p>

<p><strong>METHODS: </strong>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.</p>

<p><strong>RESULTS: </strong>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 β-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.</p>

<p><strong>CONCLUSIONS: </strong>We identified 6 healthcare-associated infection topics and 6 antimicrobial stewardship topics as potentially high-impact targets for pediatric research.</p>
