Background: Pneumonia accounts for over half a million older adult emergency department (ED) visits annually, but ED pneumonia diagnosis is inaccurate. Geriatric-specific pneumonia diagnostic criteria exist for other settings; no prospective data exist to determine if application in the older adult ED population is feasible. The objective was to prospectively evaluate the utility of four current diagnostic criteria (Loeb; Modified McGeer; Infectious Disease Society of America/American Thoracic Society; American College of Emergency Physicians) in older adult ED patients.

Methods: This was a prospective, observational cohort study of older adult ED patients ≥65 years of age in two U.S. EDs with suspected pneumonia defined as having chest radiography ordered and treating physician suspicion. The standard we used for defining the presence, absence, or inability to determine a diagnosis of pneumonia diagnosis was expert physician chart adjudication. We report the summary statistics for demographic characteristics and symptoms/exam findings and sensitivity, specificity, and likelihood ratios with 95% confidence intervals of the existing diagnostic criteria. Pre-specified cutoff values of a positive LR >10 and a negative LR <0.3 were considered clinically significant.

Results: Of 135 patients enrolled, 27 had pneumonia by adjudicator review. Typical patient-reported pneumonia symptoms, such as fever (18.5%) and new/worse cough (51.9%), were not consistently present in pneumonia. The IDSA/ATS and ACEP criteria had positive LR >10 and negative LR <0.3; however, all confidence intervals included pre-specified cutoffs.

Conclusions: Older adults presented to the ED with low frequency of typical pneumonia symptoms. Although existing diagnostic definitions had promising test characteristics, they may not perform well enough for clinical application without refinement.

Background: There are likely many contributors to variation in the rate of cognitive decline in middle and late adulthood, including individual and neighborhood socio-economic factors. This study examines whether individual socio-economic factors, namely income and wealth, correlate with cognitive decline, in part, through neighborhood-level social and material disadvantage.

Methods: Using the three waves of data collection from the Canadian Longitudinal Study on Aging (CLSA), this study included 51,338 participants between the age of 45 and 85 years at baseline (51% female). Individual socio-economic status (SES) was assessed by annual household income and by the current value of savings and investments. Neighborhood disadvantage was measured by area-based material and social deprivation indices. Cognition was measured at each wave using verbal fluency, mental alternations, and delayed word recall. Latent change score models, incorporating direct and indirect pathways, were constructed to estimate the indirect effect of individual SES on cognitive change through area-level disadvantage. Multi-group models were constructed on the basis of age-group (45-64 years; 65-74 years; or 75+ years) to allow for varying estimates across age.

Results: Among 45-64-year-olds, income and wealth had indirect effects on initial cognitive level and on rate of cognitive decline through material disadvantage (standardized indirect effects = 0.01, p < 0.001), but only wealth had an indirect effect through social disadvantage (p = 0.019). Among 65-74-year-olds, income and wealth had indirect effects on initial cognitive level (p < 0.01) but not on rate of cognitive decline (p > 0.05), and among 75+ year-olds, no indirect effects were observed (p > 0.05). Wealth and income had direct effects, independent of neighborhood disadvantage, on cognition in all age groups (p < 0.05).

Conclusions: Among middle-aged adults, greater individual SES may mitigate cognitive decline, in part, by allowing individuals to live in more materially and socially advantaged neighborhoods.

Background: Palliative care improves the quality of life for people with life-limiting conditions, which are common among older adults. Despite the Veterans Health Administration (VA) outpatient palliative care expansion, most research has focused on inpatient palliative care. This study aimed to compare veteran characteristics and hospice use for palliative care users across care settings (inpatient vs. outpatient) and dose (number of palliative care encounters).

Methods: This national cohort included veterans with any VA palliative care encounters from 2014 through 2017. We used VA and Medicare administrative data (2010-2017) to describe veteran demographics, socioeconomic status, life-limiting conditions, frailty, and palliative care utilization. Specialty palliative care encounters were identified using clinic stop codes (353, 351) and current procedural terminology codes (99241-99245).

Results: Of 120,249 unique veterans with specialty palliative care over 4 years, 67.8% had palliative care only in the inpatient setting (n = 81,523) and 32.2% had at least one palliative care encounter in the outpatient setting (n = 38,726), with or without an inpatient palliative care encounter. Outpatient versus inpatient palliative care users were more likely to have cancer and less likely to have high frailty, but sociodemographic factors including rurality and housing instability were similar. Duration of hospice use was similar between inpatient (median = 37 days; IQR = 11, 112) and outpatient (median = 44 days; IQR = 14, 118) palliative care users, and shorter among those with only one palliative care encounter (median = 18 days; IQR = 5, 64).

Conclusions: This national evaluation provides novel insights into the care setting and dose of VA specialty palliative care for veterans. Among veterans with palliative care use, one-third received at least some palliative care in the outpatient care setting. Differences between veterans with inpatient and outpatient use motivate the need for further research to understand how care settings and number of palliative care encounters impact outcomes for veterans and older adults.

Background: Federal policies targeting antipsychotic use among nursing home (NH) residents may have increased reporting of diagnoses for approved uses, including schizophrenia, Tourette's syndrome, and Huntington's Disease (called "exclusionary diagnoses" because they exclude residents from the antipsychotic quality metric). We assessed changes in new exclusionary diagnoses among long-stay NH admissions specifically with dementia following federal policies.

Methods: Retrospective, quarterly, interrupted time-series analysis (2009-2018) of new long-stay NH residents with dementia and no exclusionary diagnoses reported before NH admission. The National Partnership and the addition of facility level antipsychotic use to the Five Star Quality Rating system were key time exposures. Outcome was quarterly facility level predicted percentage of exclusionary diagnoses within 2 years of admission stratified by NH characteristics.

Results: For 264,095 long-stay admissions, mean percentage of new exclusionary diagnoses was 2.2% before the Partnership. After the Partnership, there was an unadjusted increase in the percentage over time (slope change, 0.044, p = 0.018), but the percentage never exceeded 2.9%. The Partnership contributed to a one-time decrease in diagnoses in NHs with an intermediate percentage of Black residents (-1.29%, p = 0.004). Before the Partnership, diagnoses were increasing among not-for-profit relative to for-profit NHs (0.044; p = 0.012), but after the Partnership, the pattern reversed. For-profit NHs saw an increase (+0.034, p = 0.002); not-for-profit NHs experienced a decrease (-0.014, p = 0.039). Quality Rating modifications had no significant effect.

Conclusions: Exclusionary diagnosis reporting among long-stay NH residents with dementia, the group most at risk from antipsychotics, did not increase in response to federal policies. Evaluation of reasons for the observed increase in exclusionary diagnoses among non-dementia NH residents is warranted along with continued attention to how to incentivize the appropriate use of medications in residents with dementia that is crucial for high-quality NH care.

Background: Spousal loss is a stressful life event that is associated with loneliness and social isolation, both of which affect mental and physical health. The primary objective of this paper was to synthesize longitudinal studies that investigated loneliness and social isolation in widowhood.

Methods: A systematic search of the literature was conducted using three electronic databases. 26 longitudinal studies published through June 2024 were included for further analysis. Participant characteristics, study design, and key findings were extracted.

Results: Most studies were from the United States or Europe, included more widows than widowers, and assessed loneliness in older adults aged >60 years. Loneliness peaked directly following spousal death, but findings were inconsistent regarding the lasting effects of widowhood. Heterogeneity in the longitudinal trajectories of loneliness was noted, with studies showing linear increases, decreases, or curvilinear relationships over time. Several factors modified the relationship between widowhood and loneliness, including volunteerism, military experience, income, and age. Widowers consistently reported greater loneliness and worse social isolation when compared with widows. Few studies investigated social isolation specifically, but those that did found that social isolation may decrease in widowhood.

Conclusions: As the world grapples with a social pandemic of loneliness and social isolation, widowed adults may be uniquely affected. Few studies investigated the longitudinal trajectory of loneliness and especially social isolation in widowhood, and those that did found heterogenous results. Future work is needed to understand why some widowed adults are uniquely affected by feelings of loneliness and social isolation while others are not, and whether potentially modifiable factors that moderate or mediate this relationship could be leveraged by psychosocial interventions.
