BACKGROUND:Effective interpersonal communication is associated with improved health-related outcomes, yet it is unclear to what extent this occurs in triadic clinic visits for persons living with dementia (PLWD) and few tools exist to characterize triadic interpersonal communication and assess its effectiveness. The objective of this project is to characterize the interpersonal communication that occurs during triadic visits for PLWD, examine how interpersonal communication is related to health outcomes and use this understanding to adapt an innovative clinic visit audio recording intervention, HealthPAL (Personal Audio Library) for use in this setting. METHODS:Following the NIH Stage Model, we will redesign a visit recording platform, HealthPAL, which leverages natural language processing to structure visit information. In Aim 1, we will use an explanatory sequential mixed methods design. Informed by the Behavior Change Wheel, targets for behavior change will be identified using quantitative assessment of interpersonal communication during triadic visits (200 dyads, 3 visits annually; ∼600 visits), supplemented by semi-structured interviews with a purposive sample of triads (n = 42); In Aim 2, we will use participatory design methods (n = 60) to redesign HealthPAL using findings from Aim 1; and in Aim 3, we will use an open label, single-arm, multi-site pilot trial (n = 30) to determine usability, feasibility and acceptability of HealthPAL and gather preliminary data on its impact on interpersonal communication in triadic AD/ADRD visits. We hypothesize: (1) Constructs from models of interpersonal communication will be associated with health-related outcomes; (2) HealthPAL will surpass usability, feasibility, and acceptability metrics for dyads and clinicians. DISCUSSION/CONCLUSIONS:This work is a necessary first step to improving PLWD triadic care by identifying behaviors that impact triadic interpersonal communication and their associations with health-related outcomes. The novel intervention that we will develop--the use of visit recordings--and the diverse and extensive data we will collect will serve as a unique resource that can be leveraged to address other gaps in clinical knowledge related to the care of PLWD.

BACKGROUND:The Enhanced Quality in Primary Care for Elders with Diabetes-ADRD (EQUIPED-ADRD) is a quality improvement and pragmatic cluster-randomized controlled trial that uses clinical decision guidelines to streamline the care of older adults with diabetes mellitus and Alzheimer's disease/Alzheimer's disease-related Dementia (DM-AD/ADRD). This study tests whether the EQUIPED-ADRD intervention will increase the proportion of older adults with DM and AD/ADRD with desirable glycemic ranges, and reduce treatment burden, dementia severity, and healthcare utilization among participants and their care partners in the intervention arm compared to those in the control arm. METHODS:We will recruit older adults (≥65 years) with both DM and AD/ADRD diagnoses, who have care partners, and receive care at the enrolled New York University clinics. The intervention involves the use of panel managers to streamline the integration of clinical decision guidelines among primary care providers and improve the experiences of care partners and patients. Those in the control arm will have no panel management. We will conduct surveys and interviews, and extract data from EMR and Medicare claims to assess the association between the intervention and primary and secondary outcomes. The primary outcome is achieving within-range HbA1c, while the secondary outcomes include measures of healthcare utilization. Patient and care partner treatment burden, dementia symptoms, and care partner diabetes care distress. CONCLUSIONS:The EQUIPED-ADRD intervention (implemented between 2018 and 2021) will assess the effect of an institutional guideline on the quality of life and health outcomes of older adults with DM-AD/ADRD and their care partners. Clinical Trial NumberNCT03723707.

BACKGROUND:Infliximab (IFX) is commonly used in the management of acute severe ulcerative colitis (ASUC), yet up to 30% of individuals still require colectomy within 1 year. Clinical data characterizing these patients, however, are limited. AIMS/OBJECTIVE:We aimed to determine risk factors for colectomy among patients with ASUC who received in-hospital IFX treatment. METHODS:We performed a retrospective analysis of patients with ASUC who were treated with at least one dose of IFX while admitted between 2014 and 2022. Cox proportional hazards (PH) models were used to assess demographic, clinical, and laboratory risk factors for colectomy within 30 days and 1 year of IFX initiation. RESULTS:Overall, 36/170 (21.2%) patients underwent colectomy within 1 year of IFX initiation, with 22 (12.9%) individuals requiring colectomy within 30 days. On univariable analysis, concomitant Clostridioides difficile infection during admission, a ≤50% decrease in C-reactive protein (CRP) and experiencing 3 or more bowel movements per day within 48 hours after an initial IFX dose were significantly associated with 1-year colectomy. On multivariable Cox PH analysis, C. difficile infection during admission (aHR=2.92, 95% CI: 1.12-7.58) and a higher CRP/albumin ratio on admission (aHR=1.13, 95% CI: 1.01-1.27) were associated with increased colectomy risk within 1 year of IFX initiation. CONCLUSIONS:C. difficile infection and a higher CRP/albumin ratio on admission are associated with decreased time to colectomy within 1 year of IFX among patients presenting with ASUC. These factors may aid in early risk stratification to minimize delays in JAK-inhibitor initiation or surgical referral.

INTRODUCTION/BACKGROUND:The Neighborhoods Study (TNS) is a novel investigation of adverse social exposome and brain health leveraging 22 Alzheimer's Disease Research Centers (ADRCs). TNS aims to understand if the adverse social exposures increase Alzheimer's disease and related dementias (ADRD) risk. METHODS:TNS uses innovative methods to determine lifetime addresses of living (n = ≈ 3116) and brain bank cohorts (n = ≈ 8637). Addresses are linked to time-concordant adverse social exposome using the Area Deprivation Index (ADI) and summarized over time. Brain health measures are provided by the National Alzheimer's Coordinating Center. RESULTS:We highlight a general overview and methodology of TNS. Data collection is ongoing; however, preliminary findings indicate that the adverse social exposome is related to ADRD biomarkers, neuropathology, and cognitive function. DISCUSSION/CONCLUSIONS:TNS is the largest study of adverse social exposome and ADRD, using the ADRC network to build robust scientific consortia. Its findings will inform ADRD interventions, precision medicine, and policy. HIGHLIGHTS/CONCLUSIONS:The Neighborhoods Study (TNS) investigates adverse social exposome and brain health. TNS is a collaboration among 22 Alzheimer's Disease Research Centers. TNS will give insight on environmental and exposomal factors which may be modifiable. Participant lifetime addresses are linked to temporal adverse social exposome metrics. This study's findings will inform precision approaches to mitigate dementia risk.

BACKGROUND:Fall injury is a sentinel event for mortality among older adults, and activity intensity may play a role in mitigating this outcome. This study assessed the relationship between activity intensity and all-cause mortality following fall injury among community-dwelling U.S. older adults. METHODS:For this retrospective cohort study, we pooled 12 years of data from the National Health Interview Survey and identified older adults (aged 65 years and older) who sustained fall injuries (N = 2454). The outcome variable was time to death following a fall injury. We defined activity intensity as a binary variable, none-to-low and normal-to-high, using the American Heart Association's weekly 500 Metabolic Equivalent of Task (MET) as a cutoff. We controlled for sociodemographic, healthcare access, and health characteristics; performed survey-weighted Cox proportional hazard regression analysis; and reported the adjusted mortality risks (plus 95% confidence interval (CI)). RESULTS:The survey comprised 2454 older adults with fall injuries, representing 863,845 US older adults. The population was predominantly female (68%), non-Hispanic White (85%), and divorced/separated (54%). During the follow-up period, 45% of the study population died. Approximately 81% of the study population had low activity levels. However, between 2006 and 2017, the proportion of the study population with low physical activity decreased from 90% to 67%. After adjusting for sociodemographic, healthcare access, and health characteristics, none-to-low activity intensity was associated with 50% increased mortality risk (aHR: 1.50; 95% CI: 1.20-1.87). CONCLUSIONS:Promoting higher physical activity levels may significantly reduce the all-cause mortality risk following fall injury among older adults.

OBJECTIVES/UNASSIGNED:Caregivers may experience treatment burden as they care for persons living with dementia and diabetes. This study aims to adapt and validate the Treatment Burden Questionnaire (TBQ) for use among caregivers. METHOD/UNASSIGNED: = 311). The original patient-focused 15-item TBQ scale was adapted to measure caregiver-related burden. We assessed face validity for each item, performed item analysis, and computed the scale's internal consistency (Cronbach alpha). We also performed principal component analysis (PCA) and correlation to assess the construct and convergent validity, respectively. RESULTS/UNASSIGNED:All 15 items in the caregiver TBQ demonstrated face validity, had high acceptability, with a Cronbach alpha of 0.89. The PCA identified three domains-medication monitoring burden, healthcare access burden, and social care burden. Subscale domain reliability was 0.86, 0.77, and 0.77, respectively. The three subscales exhibited significant small to moderate correlations with the stress thermometer, Medical Outcomes Study, and physical and mental health Patient-Reported Outcomes Measurement Information System scores. CONCLUSION/UNASSIGNED:The caregiver TBQ is a reliable and valid tool that captures domains of medication monitoring, healthcare access, and social care burden.

Factorial study designs can be important for understanding the effectiveness of interventions when multiple interventions are under investigation. In this design setting, a unit of randomization can be assigned to any combination of interventions. The rationale for taking this kind of approach can vary depending on the specific questions targeted by the research. These questions, in turn, have implications for the way in which the analyses will be conducted. The goal in this paper is to describe how we developed a factorial design along with a Bayesian analytic plan for a large cluster-randomized trial-the Emergency Departments LEading the transformation of Alzheimer's and Dementia care (ED-LEAD) study-focused on improving care for persons living with dementia.

OBJECTIVES/OBJECTIVE:To assess the acceptability of an infection-control prevention strategy during the COVID-19 pandemic for skilled nursing facilities (SNFs) staff and residents, to describe implementation challenges and potential solutions, and to explore intervention impact perceptions. DESIGN/METHODS:Qualitative investigation of a multimethod pragmatic clinical trial designed to develop and test a novel cohorting intervention to mitigate infection transmission in SNFs during the COVID-19 pandemic. SETTING AND PARTICIPANTS/METHODS:We used a purposive sample of staff and residents in 2 New York City nonprofit SNFs participating in the intervention trial. METHODS:We developed a novel cohorting strategy to minimize infection transmission by using infection risk (vaccination or prior infection history) to assign staff to specific residents. We employed a qualitative descriptive approach using content thematic analysis of semistructured interviews with staff and residents to identify themes of acceptability, challenges, and potential impact. RESULTS:Seventy-one staff and 16 residents completed semistructured interviews. Staff and residents supported the intervention. However, both identified challenges, including concerns that switching assignments could lead to staffing issues and care discontinuity. Staff identified communication about the intervention as both a challenge and potential solution, citing a desire for clear and consistent communication across all employees. Staff felt the intervention had potential impact in reducing infection risk fear, promoting effective protective equipment usage, and encouraging more interaction and less isolation than standard prevention practices. CONCLUSIONS AND IMPLICATIONS/CONCLUSIONS:We developed a novel and acceptable preventive strategy that may increase residents' flexibility and reduce their isolation as well as staff stress. Clear, consistent, and proactive communication may improve intervention acceptability and perceptions about impact. Similar infection-control protocols might be adapted for different long-term care infection risks. Communication at all staffing levels and with residents is essential to ensure the intervention is acceptable to both. Future trials could include social isolation and staff burnout as potential outcomes.

OBJECTIVES/OBJECTIVE:We examined trends in the socioeconomic distribution of work schedules from 1990s to 2010s and how early adulthood disadvantages are associated work schedules over working age. METHODS:In a representative sample of U.S. workers(N = 3,328), we calculated recycled predictions of day, evening, night, and long shift prevalence associated with time-period. Logistic regression was used to analyze the association of non-day shifts with age and its variations by early adulthood disadvantage in U.S. baby boomers(N = 10,293). RESULTS:Between 1990s-2010s, evening shifts increased in adults without college education and night shifts increased in the lowest income quartile. Day shifts decreased in both groups. Being Black, not attending college, and poverty were associated with non-day shiftwork throughout working age. CONCLUSIONS:Evening and night shifts may have replaced day shifts in disadvantaged populations between 1990s-2010s. Early disadvantages may have sustained effects on work schedules.

BACKGROUND:Sarcopenia has been associated with adverse postoperative outcomes in older age cohorts, but has not been assessed in older adults with inflammatory bowel disease (IBD). Further, current assessments of sarcopenia among all aged individuals with IBD have used various measures of muscle mass as well as cutoffs to define its presence, leading to heterogeneous findings. METHODS:In this single-institution, multihospital retrospective study, we identified all patients aged 60 years and older with IBD who underwent disease-related intestinal resection between 2012 and 2022. Skeletal Muscle Index (SMI) and Total Psoas Index (TPI) were measured at the superior L3 endplate on preoperative computed tomography scans and compared through receiver operating characteristic curve. We then performed multivariable logistic regression to assess risk factors associated with an adverse 30-day postoperative outcome. Our primary outcome included a 30-day composite of postoperative mortality and complications, including infection, bleeding, cardiac event, cerebrovascular accident, acute kidney injury, venous thromboembolism, reoperation, all-cause rehospitalization, and need for intensive care unit-level care. RESULTS:A total of 120 individuals were included. Overall, 52% were female, 40% had ulcerative colitis, 60% had Crohn's disease, and median age at time of surgery was 70 years (interquartile range: 65-75). Forty percent of older adults had an adverse 30-day postoperative outcome, including infection (23%), readmission (17%), acute kidney injury (13%), bleeding (13%), intensive care unit admission (10%), cardiac event (8%), venous thromboembolism (7%), reoperation (6%), mortality (5%), and cerebrovascular accident (2%). When evaluating the predictive performance of SMI vs TPI for an adverse 30-day postoperative event, SMI had a significantly higher area under the curve of 0.66 (95% CI, 0.56-0.76) as compared to 0.58 (95% CI, 0.48-0.69) for TPI (P = .02). On multivariable logistic regression, prior IBD-related surgery (adjusted odds ratio [adjOR] 6.46, 95% CI, 1.85-22.51) and preoperative sepsis (adjOR 5.74, 95% CI, 1.36-24.17) significantly increased the odds of adverse postoperative outcomes, whereas increasing SMI was associated with a decreased risk of an adverse postoperative outcome (adjOR 0.88, 95% CI, 0.82-0.94). CONCLUSIONS:Sarcopenia, as measured by SMI, is associated with an increased risk of postoperative complications among older adults with IBD. Measurement of SMI from preoperative imaging can help risk stratify older adults with IBD undergoing intestinal resection.
