Differences in the Measurement of Comorbidities Based on ICD-10-CM Coding Definitions Using Medicare Advantage Encounter Data and Fee-For-Service Claims
BACKGROUND: Medicare Advantage (MA) encounter data became available for research in 2019; data quality concerns remain. OBJECTIVES: We evaluated the consistency of ICD-10-CM comorbidity coding between MA and Fee-For-Service (FFS) data. METHODS: We used round 7 (2017) of the National Health and Aging Trends Study (NHATS) linked to Medicare enrollment, MA encounter, and FFS claims (2016-2017). We included participants continuously enrolled in MA or…
Generative AI personas considered harmful? Putting forth twenty challenges of algorithmic user representation in human-computer interaction
Shows how GenAI fundamentally transforms existing persona development issues through evolutionary amplification rather than creating entirely new problems, with traditional biases becoming algorithmic discrimination and manual inconsistencies becoming convincing AI hallucinations. • Reveals how traditional limitations manifest differently in GenAI contexts across transparency, fairness, reliability, and control domains, with expert validation sho…
Digital Duality
Burnout among healthcare professionals is a critical issue that significantly impacts employee well-being, patient care, and healthcare outcomes. As digital transformation in the public sector progresses, healthcare has not been exempted from these changes. This paper leverages the Job Demands-Resources (JD-R) model to explore how mobile technology impacts burnout, positing it as a dual factor in this dynamic. Mobile technology, while streamlinin…
Performance of a Claims-Based Frailty Proxy Using Varying Frailty Ascertainment Lookback Windows
BACKGROUND: Frailty is an aging-related syndrome of reduced physiological reserve to maintain homeostasis. The Faurot frailty index has been validated as a Medicare claims-based proxy for predicting frailty using billing information from a user-specified ascertainment window. OBJECTIVES: We assessed the validity of the Faurot frailty index as a predictor of the frailty phenotype and 1-year mortality using varying frailty ascertainment windows. RE…
Mobility Device Use and Frailty Progression in Community-Dwelling Older Adults With Mobility Limitations
Objective: Examine the association between mobility device use and changes in a frailty index (FI) over one year in community-dwelling older adults with mobility limitations. Methods: Analyses utilized 2015–2016 data from the National Health and Aging Trends Study community-dwelling older adults ( n = 3934). We calculated a validated 40-item deficit accumulation frailty index (FI) in 2015 and 2016 and compared one year change in FI in older adult…
Socioeconomic Status & Health Disparities
Research indicates that the relationship between socioeconomic status (SES) and health outcomes are robust, though no ‘gold standard’ as to what best captures SES exists. Many studies use individual proxies to control for SES, but there are a number of limitations to doing so. Additionally, little research has been conducted as to how to develop a US-based composite SES index that can be utilized across various datasets. The aim of the study is t…
Management and leadership competencies among spiritual care managers
Both the healthcare and religious landscapes in the United States are rapidly changing. Despite the dynamic environment that spiritual care managers face, many do not receive management training prior to assuming their roles and many receive little or no training once they are in their roles. This study used mixed methods to examine the applicability of the National Center for Healthcare Leadership (NCHL) competency model to spiritual care manage…
Association of Advance Care Planning Visits With Intensity of Health Care for Medicare Beneficiaries With Serious Illness at the End of Life
In this cohort study of US Medicare beneficiaries, billed ACP services during the EOL course of patients with serious illness were relatively uncommon, but if they occurred before the last month of life, they were associated with less intensive use of EOL services. Further research on the variables affecting hospice use and expenditures in the EOL period and the differential effect of late ACP is recommended to understand the relative role of ACP…
Frailty and Differences in Self-Reported Sexual Functioning Among Older Females and Males in National Social life, Health and Aging Project
Frailty may be a clinical indicator of sexual functioning decline for males more than females
Screening Value of Social Frailty and Its Association with Physical Frailty and Disability in Community-Dwelling Older Koreans
Population aging is a challenge, therefore efficient frailty screening has been increasingly emphasized for mass older populations. This study aimed to evaluate the prevalence of social frailty and its association with physical frailty, geriatric syndromes and activity of daily living (ADL) disability in community-dwelling older adults. A cross-sectional study was conducted with 408 older adults (mean age, 75 years; 58% female) in the Aging Study…
The Risk Factors of Sexual Behavior Among Middle School Students in South Korea
Understanding sexual intercourse among adolescents is an important public health issue. To establish the risk factors of coitus among youth, we use 11th Korea Youth Risk Behaviour Web-based Survey data. Participants were completed a questionnaire on sexual behaviour, alcohol consumption, smoking, mental health, physical activity, weight management, health equity, and others. Among boys, coitus experience was higher in boys-only schools than in mi…
Gender Diversity on Corporate Boards
We show that gender diversity in corporate boards could improve firm value because of the contributions that women make to the board. Prior studies examine valuation effects of gender-diverse boards and reach mixed conclusions. To help resolve this conundrum, we consider how gender diversity could affect firm value, that is, what mechanisms could explain how female directors benefit corporate board performance. We hypothesize and provide evidence…
Service Quality, Perceived Value, Customer Satisfaction, and Behavioral Intention Among Fitness Center Members Aged 60 Years and Over
Our aim in this study was to examine the structural relationships among service quality, perceived value, customer satisfaction, and behavioral intention. Participants, who were all aged 60 years or older and who were members of a sport and fitness center, completed surveys to assess these relationships. Scanning electron microscopy results showed that provision of high-quality services for older adult consumers in a sport and fitness center elev…

Modifiable Cardiovascular Risk Factors Among Individuals in Low Socioeconomic Communities and Homeless Shelters
To understand cardiovascular health in low socioeconomic populations, we analyzed the data from 426 low socioeconomic community-dwelling males and females and 287 homeless males in Philadelphia. Despite higher prevalence of smoking and hypertension, the proportion of homeless participants at increased risk for coronary heart disease was comparable with that of low socioeconomic community-dwelling participants. Among various characteristics, emoti…
