Background: Up to one third of older adults with diabetes (DM) have co-occurring cognitive impairment and/or Alzheimer's disease and Related Dementias (ADRD). These patients are more likely to experience episodes of hypo and hyperglycemia. The American Geriatric Society (AGS) and American Diabetic Association (ADA) recommend liberalizing hemoglobin (Hb) A1c targets for patients with multiple comorbidities, but the impact of ADRD on glycemic management of patients with DM-ADRD is unknown.
Method(s): Within the primary care and endocrine clinics in the NYU Langone Health System, we collected characteristics of DM-ADRD patients participating in a DM-ADRD clinical quality improvement program. We administratively collected patients' most recent (within18 months) HbA1c from the Electronic Medical Record. We also surveyed the English and Spanish-speaking caregivers (CG) of these DM-ADRD patients. The CG survey included a measure of CG-reported patient dementia severity using the Dementia Severity Rating Scale (DSRS). We examined the relationship between the DSRS score and HbA1c.
Result(s): Patients (n=173) had a mean age of 79.7 (+/-7.18) and a mean HbA1c of 7.08%. 63% (n=106) were female, 63% (n=106) white; 37% (n=64) identified as being Latino/Hispanic. The mean DSRS score was 25 (+/-12.7) (range: 0-54), within the range of moderate cognitive impairment (18-36). Those older than 75 and those who were Spanish speaking had higher DSRS scores (26.1, p=.02; and 26.7, p=.04, respectively). Mean HbA1c of patients in the severe DSRS range (scores 37-54) was 6.81 (N=35) and was lower than in patients with moderate and mild dementia severity (mean 7.15 and 7.24, respectively); however, this difference was not statistically significant.
Conclusion(s): While the data does not confirm a statistically significant relationship between dementia severity and lower A1c, this finding is worrisome for DM-ADRD patients. Our data suggests possible overtreatment and if confirmed, there is a clear need for increased family and provider education and quality improvement programs for this vulnerable population

Racial minorities experience a high burden of food insecurity relative to non-Hispanic whites. Government-subsidized nutrition programs can positively impact food insecurity and nutritional risk among older adults. Yet, in New York City, where nearly 60% of people over 65 years are non-white, older minorities participate in government nutrition programs at very low rates. In this commentary, we focus on 2 programs: the Child and Adult Care Food Program and Older Americans Act Nutrition Services Programs. We identify opportunities for strengthening these programs to improve their reach and engagement with diverse older adults in New York City and similarly diverse urban communities.

Background: Deconditioning from prolonged bedrest during hospitalization predisposes older patients to loss of mobility and the need for additional rehabilitation post-discharge. Despite recognition of the harms of prolonged bedrest and evidence that resistance training (RT) reverses deconditioning, few interventions have provided such exercise for hospitalized older adults. We evaluated the safety and feasibility of a novel exercise device used in a high-intensity RT routine in older age inpatients.
Method(s): In collaboration with the NYU Grossman School of Medicine Center for Healthcare Innovation and Delivery Science we developed a lightweight, portable RT device, which attaches to a hospital bed footboard and allows for over 20 exercises in 4 categories: upper-body, lower-body, back and core. We recruited and trained willing patients to use this device with a goal of completing 7 exercises per workout. We included inpatients (age > 70) on a general medical unit with a PT/OT order. Those having exercise limiting orthopedic or neurologic disability, and acute cardiopulmonary limitations were excluded. Each workout included exercises from each category, 10-20 isometric 3-second holds per exercise, and minimal rest. Patients were: (1) evaluated on their ability to complete each workout; (2) surveyed on their experience with the device; and (3) monitored for adverse events.
Result(s): 11 patients were trained using the device for an average of 2.0 total sessions per hospitalization (mean age: 80.9 years, range: 71-101; 54.5% female). Reasons for fewer sessions included early discharge, delirium, and contact precautions. Patients completed 89.3% of the exercises they performed. We noted no adverse events. 72.7% stated they would use the device on their own and 90.9% believed there is not enough exercise performed in hospitals.
Conclusion(s): This pilot study provides evidence of the safety and feasibility of a novel RT device to prevent inpatient deconditioning. Patients were eager and able to participate in RT. We did not observe fear of safety or views of high intensity RT as inappropriate for older hospitalized patients. Whether use of RT will change discharge-related outcomes requires further study

Background: Warfarin is efficacious in reducing thromboembolic risks but its use presents challenges to both patients and physicians including the need for monitoring, diet modification, and attention to drug-related interactions. Novel anticoagulants have circumvented many of these issues. Although prior research includes physician consideration of patients' perspective as important in the choice of anticoagulants, patient perceptions about anticoagulant use is unknown.
Method(s): We sought to identify patient perceptions about anticoagulant use in the Geriatrics Warfarin Clinic in Bellevue Hospital, a well-known, large safety net institution in New York City. We formulated a semi-structured telephone interview guide based on prior literature. Two geriatrics fellows (JK, NT) conducted interviews with role switches between interviewer and scribe every 3 interviews. We reviewed interview notes and identified codes. Both fellows independently analyzed all interviews and codes and categorized codes into themes. Any discrepancies were resolved by consensus discussion.
Result(s): Interviews were 10-15 minutes each. Respondents' mean age was 80.4 years (Standard deviation: 8.1); 7 were women (39%). Eight interviews were in English, five (28%) required a language interpreter and five were by proxy at patient request. Thematic saturation was reached at 18 patient interviews revealing six themes. These were: resignation about current warfarin use (n=12); lack of knowledge of alternative anticoagulation (n=16); perceived need for monitoring and efficacy checks (n=6); concerns about side effect profile (n=7); primary physician's recommendation (n=7) and dietary restrictions (n=4). Preference for warfarin use was driven by ability to know its therapeutic level and many patients expressed hesitance in switching with no monitoring procedure.
Conclusion(s): Patients' use of warfarin was generally well accepted. The primary concern was need for dietary modification. Of those patients that appeared neutral or accepting of alternative anticoagulation, the main discussion points were the drug's efficacy, side effect profile, and their physician's recommendation. This study provides useful information on guiding shared decision-making conversations about anticoagulation choice, especially in a patient demographic of predominantly low socioeconomic status individuals

Background: Social isolation is common among community dwelling older adults and is associated with adverse health outcomes. Its inverse, social engagement, depends on verbal communication, which can be disrupted by age-related hearing loss (AHRL). AHRL is mitigated with hearing aids, but hearing aid costs can be prohibitive for low income, under-resourced communities. As such, personal amplifiers or hearing assistance devices (HADs), are a feasible alternative that can be delivered at point-of-care to older adults with AHRL. Despite the link between social engagement and hearing, there is little research on mitigating hearing loss to improve patient-reported outcomes such as depressed mood and loneliness, particularly in low-income communities.
Method(s): This ongoing pilot study has enrolled older adults living in federally subsidized Los Angeles housing to assess the feasibility of community-based hearing assessment and provision of hearing assistance devices (HAD). We seek to understand the potential impact of HAD use on patient-reported symptoms. We measure self-reported hearing loss using the Hearing Handicap Inventory (HHI), and at baseline, one, and two months: social isolation using a 4-item instrument, depressed mood using the Patient Health Questionnaire (PHQ)-9, a 6-item loneliness score, and HAD utility using the International Outcome Inventory for Alternative Interventions (IOI-AI).
Result(s): Among 36 recruited participants in three buildings thus far, 30 (83%) reported having hearing difficulties (HHI >=10) and were given Pocket-Talkers. For those with self-reported hearing-related psychosocial difficulties, 8 (27%) endorsed social isolation (>1 of 4); 18 (60%) endorsed at least mild depression (PHQ-9 > 4); and 19 (63%) endorsed loneliness (>1 of 6). Among 16 who have completed 1-month follow-up, no changes have been noted, but 1-month scores on the IOI-AI (mean: 4; range 0-5) suggest very favorable utility.
Conclusion(s): Early results from this pilot study support this as a feasible intervention with positive impact associated with Pocket- Talker use. Further follow-up and subject enrollment is needed to determine whether this intervention improves patient-reported outcomes

Background: Delirium affects 14-56% of hospitalized older adults, and leads to higher morbidity and increased healthcare costs. At NYULH we implemented the EmpoweRing elder Novel Interventions (ERNI) program in 2017, modeled after Hospital Elder Life Program (HELP), but we utilize trained pre-med and pre-nursing volunteers to prevent delirium. We have shown reduced length of stay and a decreased incidence of delirium with ERNI. Here we report on ERNI as a novel method to grow the geriatrics workforce.
Method(s): Patients 65 years or older admitted to ICU, ED observation, neurology, cardiology, and general medicine units determined to be at high risk for delirium were visited by trained pre-med/ nursing volunteers who engaged them in conversations, listened to music, reoriented them, worked on puzzles, and advocated for patients' needs. We assessed nursing and volunteer satisfaction, and patient/family satisfaction using Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) data from April 2017- July 2019.
Result(s): 26/31 (84%) nurses rated volunteers 7 or higher on a scale of 1-10, and 84% of nurses felt volunteers helped prevent delirium. The volunteers expressed satisfaction with the program, 17/18 (94%), and felt appreciated by patients and families[BC1]. 16/18 (89%) volunteers plan to pursue a career in healthcare, and 17/18 volunteers (94%) plan to work with older adults. 12/18 (67%) volunteers were the first in their families to work in healthcare. Although not directly related to ERNI, patient HCAHPS scores in the Observation Unit (measured by the hospital), improved after ERNI implementation, with nursing communication increasing from 70.5% to 77% and pain communication from 34.1% to 45.6%.
Conclusion(s): Our ERNI program demonstrated high rates of nursing and volunteer satisfaction, and patients in ED Observation had increased satisfaction. Exposing pre-med/nursing volunteers to older patients in a modified HELP program may be an important step toward increasing recruitment to the geriatrics workforce. For those already considering this career, the ERNI experience might solidify those intentions. Future plans are to expand this program by recruiting more college students as volunteers

Background: Caregivers (CGs) of older-adults with Alzheimer's disease and related dementias (ADRD) and CGs of older-adults with diabetes (DM) report substantial CG burden. CG burden is known to be linked to patients' behavioral problems, poor cognition, and increased dependency. There is no literature addressing CG burden in CGs of individuals with co-occurring diabetes and dementia (DM-ADRD). The aim of this study was to identify CG and care-recipient (CR) factors associated with high levels of CG burden in CGs of DM-ADRD patients.
Method(s): This study used bivariate and descriptive statistics to analyze surveys collected as part of a quality improvement intervention being conducted at NYU Langone Health primary care and endocrine Faculty Group Practices and Family Health Centers. Inclusion criteria for patients were age >= 65, cognitive impairment, and DM with recent HbA1c > 6.4 or ever prescribed hyperglyemic medication. Telephonic surveys were conducted with CGs of eligible patients. The Treatment Burden Questionnaire (TBQ) was used to measure CG burden. TBQ results were analyzed for association with CG factors including age, sex, race, relationship to patient, education level, residence status, and level of social support, as well as CR factors including age, sex, race, dementia severity, Charlson comorbidity score, and recent HbA1c values.
Result(s): CGs that completed surveys (n=58) had a mean age of 54.3 years, 74% (n=43) female, 46% (n=27) white, 84% (n=49) were children of CRs, 70% (n=41) had education beyond 12th grade, and 55% (n=32) lived separately from CR. CRs of CGs that completed surveys (n=58) had a mean age of 80.5 years, 67% (n=39) female, 67% (n=37) white. We found CGs who were male, Asian, co-resident, with low level of social support, of CRs with more-advanced dementia, and of CRs with recent out-of-range HbA1c had significantly higher levels of CG burden (p<0.1).
Conclusion(s): Our study demonstrates there are several CG and CR factors that are associated with increased levels of CG burden in this population. Findings may assist in identification of CGs at risk for increased burden. If these results are found to be replicable, future studies should focus on the development of prevention and treatment plans consistent with these findings

BACKGROUND:Advanced Parkinson's disease (PD) is a multidimensional neurodegenerative condition with motor and non-motor symptoms contributing to increasing disability and decreasing quality of life. As the disease progresses, patients may become homebound and estranged from neurological care, with dire consequences. We describe the increasing epidemiologic burden of and individual risks faced by patients with palliative-stage PD and their caregivers. METHODS:With the aim of mitigating these risks, we designed and iterated two models of interdisciplinary home visits to maintain continuity of care and illuminate the unmet needs and barriers to care faced by this population. We describe both models in detail, with data on feasibility and patient-centered outcomes achieved in the initial model, and baseline characteristics of participants in the ongoing expanded model. Finally, we illustrate the scope and common themes of such palliative care-informed home visits with two cases. RESULTS:The pilot model involved over 380 visits with 109 individual patients. Among those patients, PD severity worsened by nearly 12 points annually on the Unified Parkinson's Disease Rating Scale (UPDRS), without a corresponding decline in quality of life. In an ongoing study of the second iteration of the model, 52 patient-caregiver dyads have completed their initial visit, with 44% bearing a diagnosis of dementia and the majority requiring an assistive device or being bedbound. Two cases highlight the critical importance of thorough medication reconciliation and home safety assessment in the comprehensive evaluation and management of such patients. CONCLUSIONS:As our population ages, therapies increase, and the number of individuals living with advanced PD and related disorders grows, so too does the imperative to recognize and address the palliative care needs of such patients and families. For many, home may be a viable, and perhaps optimal, site for this care.
