We examined the association between influenza vaccination policies at acute care hospitals and influenza vaccination coverage among healthcare personnel for the 2021–22 influenza season. Mandatory vaccination and masking for unvaccinated personnel were associated with increased odds of vaccination. Hospital employees had higher vaccination coverage than licensed independent practitioners.

Observers were randomized to time and location across two different Neonatal Intensive Care Units (NICUs) to count hand hygiene opportunities (HHOs). Mean hourly HHO was lower at night and during use of precautions, and higher in shared rooms. HHO benchmarks can support implementation of group electronic monitoring systems in NICUs.

This study evaluates the implementation of a blood culture (BCx) algorithm in the neurology ICU (NICU) to reduce BCx event (BCE) rates. Results show a reduction in BCE rates, without increasing adverse outcomes. The findings support the feasibility of BCx algorithms for improving diagnostic stewardship in the specialized NICU population.

A daily prompt to offer vaccination to inpatients awaiting transfer to rehabilitation resulted in increased SARS-CoV-2 (OR 5.64, 95% CI 3.3–10.15; P < 0.001) and influenza (OR 3.80, 95% CI 2.45–6.06; P < 0.001) vaccination. Compared to baseline, this intervention was associated with reduced incidence of viral respiratory infection during subsequent admission to rehabilitation.

Late-onset sepsis (LOS) in the neonatal intensive care unit (NICU) causes significant morbidity and mortality, yet guidance on empiric management is limited. We surveyed NICUs across Canada and the United States regarding their empiric antimicrobial regimens for LOS, thereby identifying large practice variations and high rates of empiric vancomycin use.

A 54-question survey about System Healthcare Infection Prevention Programs (SHIPPs) was sent out to SHEA Research Network participants in August 2023. Thirty-eight United States-based institutions responded (38/93, 41%), of which 23 have SHIPPs. We found heterogeneity in the structure, staffing, and resources for system infection prevention (IP) programs.

We surveyed 111 institutions’ practices for screening and decolonization of Staphylococcus aureus in presurgical patients. Institutions commonly utilize universal, targeted, or no decolonization strategies. Frequently reported products were nasal mupirocin, chlorhexidine gluconate bathing, and nasal povidone-iodine. Practice variability indicates opportunities to define optimal strategies.

Over a 2-year period, we identified Transmission from Room Environment Events (TREE) across the Johns Hopkins Health System, where the subsequent room occupant developed the same organism with the same antimicrobial susceptibilities as the patient who had previously occupied that room. Overall, the TREE rate was 50/100,000 inpatient days.

A hospital water system colonized with Legionella bacteria (three of four buildings, with > 50% of positive samples) was able to reduce detections to <1% positivity in the long term only after ClO2 was iteratively added first to the cold-water and then hot-water systems followed by pipe replacements (n = 6835 total samples).

Tape rolls are often used for multiple patients despite recommendations by manufacturers for single-patient use. We developed a survey to query Health Care Personnel about their tape use practices and beliefs and uncovered behaviors that put patients at risk for hospital-acquired infections due to tape use.

Interviews with 22 home-based primary care (HBPC) clinicians revealed that infectious disease physicians and clinical pharmacists facilitate infection management and antibiotic selection, respectively, and that local initiatives within programs support antibiotic prescribing decisions. Interventions that facilitate specialist engagement and tailored approaches that address the unique challenges of HBPC are needed.
