Delirium due to potentially avoidable hospitalizations among older adults.
This retrospective cross-sectional study examined delirium rates among 39,933 older adults hospitalized for ambulatory care-sensitive conditions (ACSCs) at a large Southeastern academic medical center from 2015 to 2019. Delirium occurred in 15.6% of admissions, with lower rates observed for ACSC admissions compared to non-ACSC admissions. Older age and higher comorbidity were significant predictors of delirium development. While delirium rates were lower for ACSC admissions, optimizing outpatient management of ACSCs remains crucial for reducing hospitalizations and associated complications like delirium.

Older adult patients and care partners as knowledge brokers in fragmented health care.
This study explores the knowledge broker roles of older adult patients and their care partners during emergency department (ED) visits. The research concludes that patients and care partners serve as information liaisons between fragmented care systems, providing details on diagnostic testing, medications, health history, and care accommodations. They engage in proactive and reactive knowledge brokering within and across ED work systems, aiding in communication and care coordination to mitigate healthcare fragmentation.

Colorectal cancer screening receipt does not differ by 10-year mortality risk among older adults.
This study examined receipt of past-year colorectal cancer (CRC screening) according to predicted 10-year mortality risk among 25,888 community-dwelling adults aged 65-84 years who were not up-to-date with screening in the nationwide National Health Interview Survey. Ten-year mortality risk was estimated using a validated index with the lowest to highest quintiles of the index ranging from 12%-79%. The authors also examined the proportion of screening performed among adults with life expectancy <10 years. They found that the prevalence of past-year CRC screening was 39.5%, 40.6%, 38.7%, 36.4%, and 35.4%, from the lowest to highest quintile of 10-year mortality risk, demonstrating that the odds of CRC screening did not differ in the lowest vs highest quintile. One-quarter of past-year CRC screening occurred in adults with life expectancy <10 years, and more than half (50.7%) of adults aged 75-84 years had 10-year mortality risk ≥50% at the time of screening. Invasive but not noninvasive screening increased as 10-year mortality risk increased among adults aged 70-79 years.

Automating risk stratification for geriatric syndromes in the emergency department.
This study discussed using automated risk stratification to implement screening programs for geriatric syndromes in the emergency department (ED). This method would reduce significant workloads at a time of record-breaking ED patient volumes, staff shortages, and hospital boarding crises. The authors defined the concept of automated risk stratification and screening using existing electronic health record (EHR) data. They discussed progress made in three potential use cases in the ED: falls, cognitive impairment, and end-of-life and palliative care; emphasizing the importance of linking automated screening with systems of healthcare delivery. They found that research progress and operational deployment vary by use case, ranging from deployed solutions in falls screening to algorithmic validation in cognitive impairment and end-of-life care, but should still be considered a potential solution.
