Randomized Controlled Trial
Modification of Blood Test Draw Order to Reduce Blood Culture Contamination: A Randomized Clinical Trial.
Blood culture contamination leads to unnecessary interventions and costs. It may be caused by bacteria in deep skin structures unsusceptible to surface decontamination. This study was designed to test whether diversion of blood obtained at venipuncture into a lithium heparin tube prior to aspiration of blood culture reduces contamination. ⋯ NCT03966534.

Women are underrepresented in human immunodeficiency virus (HIV) research in the United States. To determine if women screening for HIV clinical trials enrolled at lower rates than men, we performed a retrospective, cross-trial analysis. ⋯ In the absence of evidence of significantly higher trial screen-out for women, approaching more women to screen may increase female representation in HIV trials.

Although rare, subclinical tuberculosis disease can be missed during evaluations for latent tuberculosis infection, and can manifest with symptoms during latent tuberculosis treatment. Among over 8000 patients treated for latent tuberculosis we found no evidence of acquired drug resistance, underscoring the safety of rifampin monotherapy for latent tuberculosis.

Across the world, healthcare workers (HCW) are at a greater risk of infection by the novel coronavirus 2019 (COVID-19) due to the nature of their work. The Los Angeles County Department of Public Health (LAC DPH) set out to understand the impact of COVID-19 on healthcare facilities and HCWs by tracking and analyzing data from case-patient interviews of HCWs. As of May 31st, over three months into the pandemic, nearly 5,500 positive HCWs were reported to LAC DPH, representing 9.6% of all cases. ⋯ Overall, compared to all LAC cases, HCWs reported lower rates of hospitalization (5.3% vs. 12.2%) and death (0.7% vs. 4.3%) from COVID-19. There are many factors that increase HCWs risk of infection, including high risk work environment, limited supply of personal protective equipment, and even pressure to help and work during a pandemic. In response to these data, LAC DPH created resources and provided guidance for healthcare facilities to best protect their patients and staff during the COVID-19 pandemic.
