To assess the effectiveness of a 3-question decision-support tool to guide the diagnosis and treatment of urinary tract infections (UTIs) in acute care hospitalized patients as an antibiotic and diagnostic stewardship initiative.

Retrospective cohort study.

Four acute care hospitals within the same health system in Miami, FL.

124, admitted from the emergency department and hospitalized adult patients, treated with antibiotics for the indication of a UTI between March and April 2023.

We developed a 3-step clinical decision-support tool (CDST) to evaluate the appropriateness of urine cultures and antibiotic treatment. The tool’s recommendations when deciding to prescribe antibiotics were compared with the actual need for treatment throughout the hospitalization, up to the time of patient discharge.

Overall, 31% of antibiotics prescribed for UTIs were inappropriate and met the criteria for asymptomatic bacteriuria (ASB) based on the CDST. Prospective implementation of the decision-support tool could potentially reduce antibiotic use by 33.6%, corresponding to 265 days of unnecessary therapy. The sensitivity and specificity of the tool were calculated to be 98.6% and 100%, respectively, indicating high accuracy in identifying the need for antibiotic treatment. Urinalysis alone was insufficient to differentiate between symptomatic UTIs and ASB, with leukocyturia present in 95.3% of UTI cases and 94.6% of ASB cases (P = 0.87).

Implementing a 3-question CDST may reduce unnecessary laboratory work-up and treatment for ASB improving the diagnostic and antimicrobial stewardship of UTIs.

To assess reasons for noncompliance with COVID-19 vaccination among healthcare workers (HCWs).

Cohort observational and surveillance study.

Sheba Medical Center, a 1,600-bed tertiary-care medical center in Israel.

The study included 10,888 HCWs including all employees, students, and volunteers.

The BNT162b2 mRNA COVID-19 vaccine was offered to all HCWs of the hospital. Noncompliance was assessed, and pre-rollout and post-rollout surveys were conducted. Data regarding uptake of the vaccine as well as demographic data and compliance with prior influenza vaccination were collected, and 2 surveys were distributed. The survey before the rollout pertained to the intention to receive the vaccine, and the survey after the rollout pertained to all unvaccinated HCWs regarding causes of hesitancy.

In the pre-rollout survey, 1,673 (47%) of 3,563 HCWs declared their intent to receive the vaccine. Overall, 8,108 (79%) HCWs received the COVID-19 vaccine within 40 days of rollout. In a multivariate logistic regression model, the factors that were significant predictors of vaccine uptake were male sex, age 40–59 years, occupation (paramedical professionals and doctors), high socioeconomic level, and compliance with flu vaccine. Among 425 unvaccinated HCWs who answered the second survey, the most common cause for hesitancy was the risk during pregnancy (31%).

Although vaccine uptake among HCWs was higher than expected, relatively low uptake was observed among young women and those from lower socioeconomic levels and educational backgrounds. Concerns regarding vaccine safety during pregnancy were common and more data about vaccine safety, especially during pregnancy, might improve compliance.
