Abstract
Using predictive analytic modelling, the Veterans Affairs has identified Veterans considered to be High Need High Risk (HNHR) requiring increased support. This pilot study sent needs assessment questionnaires to 1112 HNHR Veterans to better understand gaps regarding technology use, access, physical function, and mobility. There were 341(30.7%) respondents: 270(80.4%) Non-Hispanic, 64(18.8%) Hispanic/Latino; 210(61.6%) White, 119(34.9%) Black/African Americans; and 310(90.4%) had ≥high school education. Average Barthel(ADL) score was 81.5±22.8 and Lawton(IADL) score was 5.8±2.2. Younger Veterans (age&lt;70) were more likely able to use Internet ((117(65%) vs 74(46%)),(p≤0.01) and email (106(58.9%) vs 67(41.6%),( p≤0.01). They were also more likely enrolled in MyHealtheVet (87(48.3%) vs 58(36%),(p=0.043). Secure messaging was used by 62(34.3%) younger and 37(23%) older Veterans,(p=0.026). More higher functioning Veterans (140(55.1%)) used email than lower functioning (33(37.9%)),(p=0.018). Among higher functioning Veterans, 148(58.3%) were willing to use videoconference for care coordination and 116(45.7%) owned a smartphone or computer with camera for this; more than lower functioning Veterans (33(37.9%) and 28(32.2%)), (p≤0.01 for both). Less dependent Veterans preferred to be contacted via cellphone (88(62.4%)) or Internet (10(7.1%)) compared to the more dependent (96(48%) and 6(3%)) respectively (p=0.01). Only 71(44.1%) of older Veterans were willing to use videoconference (p≤0.01) and 54(33.5%) owned a smartphone or computer with camera,(p≤0.01). There are significant variations in technology use by age and ethnicity. However, although there are differences by functional ability, a significant number of disabled veterans are willing and able to use technology, and this may provide a way to address access barriers in this population.

Abstract
Alzheimer’s disease (AD) is a form of dementia impacting memory and cognitive function of 131 million individuals worldwide. Though early cognitive decline detection is important, cognitive screening is limited among older adults and many cases go undetected. As easy-to-use cognitive assessments are not readily available to the general population, the purpose of this investigation was to determine the ability of a 5-minute webcamera-based eye-tracking cognitive assessment to discriminate between cognitively intact adults and adults with mild cognitive impairment (MCI) or AD. This prospective study included 56 participants (age=55.9±26.8) divided into three groups: younger cognitively intact (ages 18-46 years, n=25), older cognitively intact (ages &gt;60 years, n=20), and older cognitively impaired participants with MCI or AD (ages&gt;60 years, n=13). All participants completed the Digit Symbol Substitution Test (DSST) and Visual Paired Comparison test (VPC) to assess cognition. One-way ANOVA detected differences in cognition between groups. A Pearson correlation determined the association between cognitive assessments. Additionally, multiple regression determined the ability of VPC and age to predict DSST scores. Results revealed significant differences between cognitively intact and cognitively impaired groups for VPC (p=.001) and DSST (p&lt;.001). Follow-up analyses revealed significant differences between cognitively intact and cognitively impaired adults (p=.005) with no differences between younger and older cognitively intact adults (p=.34). There was a significant association between the VPC and DSST cognitive assessments (r=.54, p&lt;.001), with VPC and age accounting for 69% of the variation in DSST. These results support the use of webcamera-based VPC as a viable option when screening tool MCI/AD.

Abstract
Tandem walk (TW) is typically assessed by the time to complete the task and the number of missteps, however, these measures suffer from limitations and may not fully capture the range of performance in this task. We developed metrics of TW by using a body-fixed, wearable sensor in young and older adults. Healthy young men (n=40) and older adult men (n=362) were studied. While wearing a 3D accelerometer on their lower back, subjects performed three different tasks: TW, usual-walking, and quiet standing. The extracted measures for TW were: High-to-Low frequency band ratio from the power spectral density from the ML axis [nu], signal vector magnitude[g], step duration[s], sample entropy from ML, AP axis[nu] and CV[%]. All of the TW metrics were significantly different in the young and older men (p&lt;0.001). Older men completed the TW with higher CV, suggesting greater stride-to-stride variability and they walked more slowly, as seen by their step duration. Additionally, the frequency ratio measure suggests that the older adults displayed less complex corrective movements in the ML axis. TW measures were modestly correlated with usual-walking (e.g., average stride time with TW step time, r=0.3; p&lt;0.001) and with quiet standing postural control (e.g., acceleration path length in the ML and AP axis with TW sample entropy in the ML axis, r=0.13; p=0.014). Metrics derived from a wearable device complement conventional TW measures and vary with age. Further work is needed to determine if TW, gait and posture metrics are differentially associated with distinct adverse health outcomes.

Abstract
The use of video-recording offers important advantages in observing and assessing the relationships between specific behaviors in health care settings. The purpose of this systematic review is to investigate and synthesize the methodological characteristics of studies using video-technology for measuring interactions between the older persons with dementia and staff in long-term care facilities. We searched Medline, Embase and CINHAL databases for published articles in English using a video-recording method for both staff and persons with dementia. Quantitative research design studies (e.g., descriptive studies or an experimental studies) were included. Among 5,605 searched papers, a total of 20 studies were selected for this review. Situations of video-recording were providing personal care (n=12), mealtime (n=6), and conversation (n=3). Concepts of measuring by video-recording were classified into two groups: 1) Staff [care practice by staff (n=13) and communication by staff (n=11)] and 2) residents [communication by resident (n=4), activities of daily life function of resident (n=8), and behavioral and psychological symptoms of dementia (n=10)]. This review demonstrates that video technologies are actively used to evaluate the relationship between quality of care and health outcomes of the elderly with dementia in many international nursing studies. This study provides the foundation for a future research using video-recording technologies to examine the interactions and relationship between staff and the residents in long-term care settings.
DESIGNING TECHNOLOGY TO SUPPORT HEALTHCARE FOR AGING ADULTS
Authors: Charness Neil H , Beach Scott R 
Published: November 2019

Abstract
Healthcare costs are rising in industrialized countries, partly as a function of managing costly chronic care conditions associated with aging populations. Of roughly 3 trillion USD expended in the U.S., almost 90% is spent on those with chronic conditions. Technology is touted as one tool to manage healthcare efficiently. However, human factors research has shown that technological systems that do not take human capabilities into account will fail to be adopted, or if adopted, will be abandoned by users. The Center for Research and Education on Aging and Technology Enhancement (CREATE) will describe research findings for four different facets of healthcare technology. Sara Czaja will provide an overview, describing technology for healthcare support. Caregiver needs are projected to rise rapidly, in part due to aging of the baby boom cohorts. We need new solutions for future generations of older adults as there will be insufficient numbers of caregivers to care for the increased number of older adults given changes in social structures. Wendy Rogers will discuss research on the design and use of televideo and robots to assist with healthcare. Neil Charness will discuss home monitoring technology, particularly practical issues around design, deployment, and maintenance, drawing on studies of heart failure patients and older adult controls. Walter Boot will discuss how gamification of healthcare interventions can help to address the adherence problem for behavior change. Scott Beach, Associate Director & Director of Survey Research Program, University Center for Social and Urban Research, University of Pittsburgh, will serve as discussant.

Abstract
For community-dwelling older adults with chronic conditions, effective symptom management is a determinant of quality of life. Providers often have poor knowledge of an individual’s symptoms experience, especially when contact is infrequent, leading to suboptimal symptom management. Many older adults receive frequent care and contact from family, friends, and other informal caregivers (ICGs). Subjective observation by ICGs is an underexplored information source, but faces barriers including ICG burden and lack of ICG knowledge. It is unclear what relevant information might be collected by ICG observations. We conducted a pilot evaluation of Philips CarePartners Mobile (CPM), a prototype smartphone application that provides communication and coordination support to a “circle” of ICGs assisting an older adult. CPM includes features enabling ICGs to share semi-structured observations. 19 caregivers (in 8 circles) used CPM for 12 weeks, contributing 397 observations and participating in interviews and other assessments. We performed a qualitative analysis of the observations, coding for presence of content relevant to dimensions in the UCSF Symptom Management Theory (perception of, evaluation of, and response to symptoms). Relevant content was found in 150 observations, with perception and assessment more common (141) than response (32). Common symptoms included mobility difficulty (31), fatigue (23), dizziness (21), pain (19), and confusion (18). Among observations without symptom-relevant content, many reported on overall mood (92), and reference to social activities was frequent. These results demonstrate that symptoms experience can be assessed using caregiver observations, although further work may be needed to enable caregivers to provide a comprehensive assessment.

Abstract
Frailty is a clinical syndrome whose signs and symptoms are predictors of health complications, making this a major public health problem. FRAILSURVEY, which was considered a good practice by several entities, is a smartphone application that allows an easy assessment of frailty, available in Portuguese, English and Italian, on both iOS and Android stores. Smartphone-based assessment has been proven to be a useful diagnostic tool for patients, although few applications have demonstrated reliability. With this work we aimed to test the reliability of FRAILSURVEY as a tool to assess frailty, and to study people’s preference on which way to assess frailty. FRAILSURVEY is a questionnaire that comprises two sets of questions: 19 about sociodemographic data, social resources, self-perception of health, nutrition, medication, psycho-social and cognitive status, and time occupation, plus a set of 15 used to assess frailty status, the Groningen Frailty Indicator (GFI). Including 427 older adults in this study, a randomized repeated measures crossover design was employed using the FRAILSURVEY questionnaire both in paper and in application, with a week of interval to reduce carryover effects. Reliability was assessed through the GFI scores obtained by the same person between the paper and application. There were no significant differences between the results on frailty assessment using the questionnaire on both paper and application. A significant correlation was noted in the total group (ICC=.794, P&lt;0.01). Our work shows that FRAILSURVEY is a reliable mobile application for frailty assessment, that can be used by older adults, caregivers, and health professionals.

Abstract
Twitter connects an international community of healthcare stakeholders, potentially augmenting access to information related to geriatric medicine. The purpose of this study is to analyze the geriatric medicine Twitter network, and we hypothesize this community has substantially grown in the last six years. We analyzed all publicly available tweets including the hashtag #geriatrics from January 1, 2013-January 1, 2019 using Symplur Signals, a health care social media analytics platform. We evaluated #geriatrics metrics over time related to activity, content analysis, user characteristics, engagement, and network analysis. A total of 159,008 tweets (containing 42.8% re-tweets) with the hashtag #geriatrics were written by 29,443 users, resulting in 393.6 million impressions. The number of tweets increased from 9,705 in 2013 to 39,151 in 2018 (32.2% compound annual growth); users increased from 3,366 in 2013 to 29,443 in 2018 (55.3% compound annual growth). Users were primarily found in the United States, United Kingdom, and Canada. The most commonly trending topic from 2013-2015 and from 2016-2018 was ‘older adults’. The top hashtags included in tweets with #geriatrics were #job, #aging, and #hpm (hospice and palliative medicine). Network analysis showed central hubs to be medical journals, provider organizations, individual physicians, and individual advocates. The top 150 influencers consisted primarily of physicians (49.1%), advocate/support organizations (13.8%), and media organizations (6.3%). The use of Twitter to promote geriatric medicine using #geriatrics has matured into an international digital community of interest. Future studies should examine hashtags related to age prevalent illnesses and hashtags likely to be used by patients.

Abstract
Osteoarthritis (OA) of the knee is one of the most common causes of pain in older adults. Clinic-based transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that has been shown to reduce pain, but no published studies have reported using home-based self-administered tDCS in older adults with knee OA. Thus, the purpose of this study was to examine the effect of home-based tDCS on experimental pain sensitivity in older adults with knee OA. Twenty community-dwelling participants aged 50–85 years with knee OA pain received ten daily sessions of 2 mA tDCS for 20 minutes at home. A multimodal quantitative sensory testing battery was completed, including heat pain tolerance, pressure pain threshold, and punctate mechanical pain. Participants (75% female) had a mean age of 61 years, and a mean body mass index in the sample was 28.33 kg/m2. All 20 participants completed all ten home-based tDCS sessions without serious adverse effects. The Wilcoxon Signed-Rank test showed that all the differences between the baseline measurements and experimental pain sensitivity measurements after 10 sessions were statistically significant. Effect sizes (Rosenthal’s R) were R = 0.35 for heat pain tolerance (P = 0.02), R = 0.40 for pressure pain threshold (P &lt; 0.01), and R = 0.32 for punctate mechanical pain (P = 0.02). We demonstrated that home-based self-administered tDCS was feasible and reduced experimental pain sensitivity in older adults with knee OA. Future studies with well-designed randomized controlled trials are needed to validate our findings.

Published: November 2019

Abstract
Older adults are more susceptible to adverse health outcomes during and after a disaster compared with their younger counterparts. Developing community resilience, or strengthening communities to reduce the negative impacts of disasters, has the potential support older adults’ health and well-being. Community-based organizations (CBOs), such as senior centers and Villages, provide social services and programming that support aging in place and may support older adults’ resilience to disasters. This study examines CBO leadership perspectives on the role of CBOs in building disaster resilience for older adults aging in place, as well as perceived barriers and facilitators to incorporating disaster resilience activities into organizational programming. In-depth interviews were conducted with a purposive sample of staff-members of CBOs serving older adults aging in place in King County, Washington. Participants included representatives from 14 organizations that varied in size, geographic setting, organizational structure, and ethnic, linguistic, and socio-economic backgrounds of organizational members. The sample included five government-run senior centers, seven non-profit senior centers, and two Villages. Interviews were audio-recorded and transcribed verbatim. We used a combined inductive and deductive approach to code and thematically analyze the data. Results indicate that local context, leadership risk perception, collaborations, and existing services and programming influence CBOs’ willingness to engage in activities supporting disaster resilience for older adults aging in place. Findings suggest that CBOs supporting aging in place may support disaster resilience for older adults by serving as a trusted source of disaster preparedness information and tailoring disaster-related messages for an older adult audience.

Published: November 2019

Abstract
The Canadian Longitudinal Study on Aging (CLSA) is a longitudinal health study that will follow individuals aged 45 to 85 for 20 years. At baseline, participants completed measures related to driving status and mental health outcomes (e.g., Center for Epidemiologic Studies Depression Scale; CES-D). In this study we examined the associations between driving status and mental health outcomes. In the baseline sample, 1,415 participants reported being former drivers and 44,694 reported being current drivers. A greater proportion of former drivers were female, older, and urban-dwelling. Compared to current drivers, former drivers had lower levels of social support, poorer self-rated physical health, and less community participation. After controlling for these covariates as well as age and sex, former drivers had greater odds than current drivers of being classified as depressed (OR=2.48, 95% CI=2.21-2.79), and of reporting psychological distress (OR=2.22, 95% CI=1.87-2.62). Using data from former drivers only, we also examined associations between variables that contributed to driving cessation and depression symptoms. Former drivers had greater odds of being depressed if they reported feeling nervous or intimidated behind the wheel (OR=1.77, 95% CI= 1.11 - 2.80), or if they experienced difficulties with the licensing process (OR=1.62, 95% CI=1.07 - 2.54), before they stopped driving. As a next step we will search for factors that may modify the relationship between driving status and mental health. The identification of factors that modify the impact of driving cessation on mental health is critical to the development of interventions that will support smoother transitions to non-driving.
SCANNING FOR CRITICAL EVENTS DURING DRIVING: VISUAL SCANNING USING EYE TRACKING TECHNOLOGY ON A DRIVING SIMULATOR
Authors: Dickerson Anne E , Gartz Rachel , Eaker Megan , Clark Brittany 
Published: November 2019

Abstract
This study explored age differences and scanning strategies for critical events using a driving simulator with eye-tracking technology. One critical skill in driving is to efficiently scan the environment. Ten young(M=26y) and 10 old(M=65y) healthy adults drove a wearing Tobii-Pro Glasses. The software analyzes areas of interest (AOI) for “percent time of fixation” as well as illustrative “heat maps” of duration of fixation. At a four-way-stop, the young fixated at the road ahead (25% fixation time), dashboard (29%), more often than left/right of their car (15%). The old fixed on the road ahead (21%) but spent more time outside the car (23%). At the hidden sign, older drivers fixated on the environment outside the road ahead more than younger drivers (26% versus 20%), but both had increased fixation to the right side of the vehicle (Y-23%, O-24%) with this event, likely looking for the sign. Heat maps of the hidden sign illustrate this, suggesting older drivers may more efficiently scan their environment. Other possibilities include the young trusting the simulator, young/old scan differently, or interference of previous simulator experience. Simulator outcomes showed age differences on gas-pedal-reaction times suggesting that older adults are more cautious, slowing down faster with critical events. Limitations include small sample and limited studies have used eye-tracking technology in driving. This study raises interesting questions, especially for medically-at-risk drivers with visual impairments. Using the eye-tracking may enhance targeting specific strategies for a variety of impairments as well as establishing a baseline of typical drivers’ visual scanning habits.
