Coronavirus disease 2019 (COVID-19) vaccination rates of a large health system reflected their respective service areas but varied by work role. Nurse vaccination rates were higher (56.9%) and rates among nursing support personnel were lower (38.6%) than those of their communities (51.7%; P < .001). Physician vaccination rates were highest (71.6%) and were not associated with community vaccination levels.

We evaluated the robustness of sterilization technologies when spores and bacteria were placed on “dirty” instruments and overlaid with blood. The results illustrate that steam sterilization is the most effective sterilization technology with the largest margin of safety, followed by ethylene oxide and hydrogen peroxide gas plasma.

We evaluated adverse drug events (ADEs) by chart review in a random national sample of 428 veterans with coronavirus disease 2019 (COVID-19) who received tocilizumab (n = 173 of 428). ADEs (median time, 5 days) occurred in 51 of 173 (29%) and included hepatoxicity (n = 29) and infection (n = 13). Concomitant medication discontinuation occurred in 22% of ADE patients; mortality was 39%.

The paradoxical relationship between standardized infection ratio and standardized utilization ratio for catheter-associated urinary tract infections (CAUTIs) in contrast to central-line–associated bloodstream infections (CLABSIs), in addition to CAUTI definition challenges, incentivizes hospitals to focus their prevention efforts on urine culture stewardship rather than catheter avoidance and care.

One of the challenges the COVID-19 pandemic put before health professions programs in the United States was how to keep students clinically in patient care. With years of impact from coronavirus and growing numbers of variants, a long-term solution to respiratory protection for health professions students is needed.

Asymptomatic SARS-CoV-2 infections are often difficult to identify because widespread surveillance has not been the norm. Using time-series analyses, we examined whether COVID-19 rates at the county level could predict positivity rates among asymptomatic patients in a large health system. Asymptomatic positivity rates at the system level and county-level COVID-19 rates were not associated.

We conducted a retrospective chart review examining the demographics, clinical history, physical findings, and comorbidities of patients with influenza and patients with coronavirus disease 2019 (COVID-19). Older patients, male patients, patients reporting fever, and patients with higher body mass indexes (BMIs) were more likely to have COVID-19 than influenza.
