A novel approach to correcting attribution of in a healthcare setting.

Objective: To describe a novel attribution metric estimating the causal source location of healthcare-associated and compare it with the current US National Healthcare Safety Network (NHSN) surveillance reporting standard.

Design: Quality improvement study.

Setting: Two acute care facilities.

The impact of autocancellation of uncollected specimens after 24 hours on reported healthcare-associated infections: A quality improvement intervention.

Objective: To assess the impact of a 24-hour autocancellation of uncollected samples in reducing reported healthcare-associated infections (HAIs).

Design: Quality-improvement, before-and-after implementation study.

Setting: The study was conducted in 17 hospitals in Pennsylvania.

Diagnostic stewardship for testing in an acute care hospital: A quality improvement intervention.

Objective: To evaluate the impact of a diagnostic stewardship intervention on healthcare-associated infections (HAI).

Design: Quality improvement study.

Setting: Two urban acute care hospitals.

Transmission visualizations of healthcare infection clusters: A scoping review.

Objective: To evaluate infectious pathogen transmission data visualizations in outbreak publications.

Design: Scoping review.

Methods: Medline was searched for outbreak investigations of infectious diseases within healthcare facilities that included ≥1 data visualization of transmission using data observable by an infection preventionist showing temporal and/or spatial relationships.

Utilizing an interview method to estimate potential bias in silent observer hand hygiene observations.

Interviewed health care workers to determine whether they had noticed a silent hand hygiene observer, thereby determining the legitimacy of the silent observers. Data supported the observers were typically unseen, and potential observer bias had a negligible role in hand hygiene compliance.

Sprayable copper and copper-zinc nanowires inks for antiviral surface coating.

Copper alloys are known for their high antimicrobial efficacy. Retrofitting high-touch surfaces in public space with solid copper components is expensive and often impractical. Directly coating copper onto these high-touch surfaces can be achieved with hot or cold spray, but the procedure is complicated and requires special equipment.
