Neighborhood Disadvantage in a Nationally Representative Sample of Community-Living Older US Adults.

Importance: Although neighborhood socioeconomic disadvantage has become the standard for evaluating contextual socioeconomic deprivation at the Census-block level, little is known about its prevalence or association with long-term mortality in nationally representative samples of older persons.

Objectives: To estimate the prevalence of neighborhood disadvantage among a nationally representative sample of community-living older adults; to identify how prevalence estimates differ based on relevant demographic, socioeconomic, geographic, clinical, and geriatric characteristics; and to evaluate the association between neighborhood disadvantage and all-cause mortality.

Design, Setting, And Participants: This cohort study analyzed linked data of community-living persons aged 65 years or older in the contiguous US participating in the National Health and Aging Trends Study (NHATS) from 2011 to 2021.

BoneScore: A natural language processing algorithm to extract bone mineral density data from DXA scans.

To develop and test an NLP algorithm that accurately detects the presence of information reported from DXA scans containing femoral neck T-scores of the patients scanned. A rule-based NLP algorithm that iteratively built a collection of regular expressions in testing data consisting of 889 snippets of text pulled from DXA reports. This was manually checked by clinical experts to determine the proportion of manually verified annotations that contained T-score information detected by this algorithm called 'BoneScore'.

Association Between Restricting Symptoms and Disability After Critical Illness Among Older Adults.

Objectives: Older adults who survive critical illness are at risk for increased disability, limiting their independence and quality of life. We sought to evaluate whether the occurrence of symptoms that restrict activity, that is, restricting symptoms, is associated with increased disability following an ICU hospitalization.

Design: Prospective longitudinal study of community-living adults 70 years old or older who were interviewed monthly between 1998 and 2018.

Changes in neighborhood disadvantage over the course of 22 years among community-living older persons.

Background: Among older persons, neighborhood disadvantage is a granular and increasingly used social determinant of health and functional well-being. The frequency of transitions into or out of a disadvantaged neighborhood over time is not known. These transitions may occur when a person moves from one location to another or when the Neighborhood Atlas, the data source for the area deprivation index (ADI) that is used to identify disadvantaged neighborhoods at the census-block level, is updated.

Social Determinants of Health and Delivery of Rehabilitation to Older Adults During ICU Hospitalization.

Importance: Older adults with socioeconomic disadvantage develop a greater burden of disability after critical illness than those without socioeconomic disadvantage. The delivery of in-hospital rehabilitation that can mitigate functional decline may be influenced by social determinants of health (SDOH). Whether rehabilitation delivery differs by SDOH during critical illness hospitalization is not known.
