Review
A Systematic Review of Delirium Biomarkers and Their Alignment with the NIA-AA Research Framework.
To identify whether delirium biomarkers aligned with the National Institute on Aging-Alzheimer's Association (NIA-AA) research framework, a conceptual model that describes the use of diagnostic biomarkers for Alzheimer's disease and other related dementias (ADRD). ⋯ Most delirium diagnostic biomarker studies did not measure amyloid, tau, and/or neurodegenerative biomarkers, making characterization of the relationship between delirium and ADRD difficult. Future delirium biomarker diagnostic studies could improve the understanding of pathophysiologic links between delirium with other conditions affecting cognition.

Observational Study
Benzodiazepine Use among Medicare, Commercially Insured, and Veteran Older Adults, 2013-2017.
Benzodiazepines (BZDs) are widely prescribed to older adults. Although prescribing has declined in the U.S. Department of Veterans Affairs (VA), Medicare introduced BZD coverage in 2013. It is unknown whether declines in the VA have been widespread among older adults in the United States. ⋯ BZD prescribing has declined much more to older adults receiving care through the VA than Medicare or commercial insurance. Other systems may learn from strategies implemented in the VA.

Almost half of deaths related to COVID-19 in the United States are linked to nursing homes (NHs). We describe among short-term and long-term residents at three NHs in Michigan the outbreak identification process, universal testing, point prevalence of COVID-19, and subsequent containment efforts, outcomes, and challenges. ⋯ Proactive and coordinated steps between NH medical directors and administrators, referral hospitals including their laboratories, and local public health officials are necessary to rapidly respond to an outbreak and limit the transmission of COVID-19. This coordinated public health approach may save lives, minimize the burden to the healthcare system, and reduce healthcare costs.
