Background: With the COVID-19 pandemic, telehealth has been increasingly used to offset the negative outcomes of social isolation and functional decline in older adults. Crucial to the success of telehealth is end user adoption. Objective: This study aims to investigate perception and acceptability of digital technology among Asian older adults. Methods: The Healthy Ageing Promotion Program for You (HAPPY) dual-task exercise was conducted virtually to participants aged ≥60 years. Questionnaires were administered digitally and collected data on demographics, perceptions of digital technology and evaluation of HAPPY, the 6-item Lubben Social Network Scale, intrinsic capacity using the Integrated Care for Older People tool, and a functional screening with the FRAIL scale and five chair rises. Descriptive analysis was used. Results: A total of 42 participants were digitally interviewed. The mean age was 69.1 (4.7) years. Hearing, vision, and 3-item recall difficulty were present in 14% (n=6), 12% (n=5), and 24% (n=10) of participants, respectively. Of the participants, 29% (n=12) had possible sarcopenia and 14% (n=6) were prefrail. Around 24% (n=10) were at risk of social isolation. Most of the participants (n=38, 91%) agreed that technology is good, and 79% (n=33) agreed that technology would allow them to be independent for longer. Over three-quarters of participants (n=33, 79%) agreed that they have the necessary knowledge, and 91% (n=38) had technological assistance available. However, 57% (n=24) were still apprehensive about using technology. Despite 71% (n=30) of older adults owning their devices, 36% (n=15) felt finances were limiting. Through digital HAPPY, 45% (n=19) of participants reported feeling stronger, 48% (n=20) had improved spirits, and 40% (n=17) and 38% (n=16) had improved mood and memory, respectively. Conclusions: The majority of older adults in this study believed in digital technology and had the necessary knowledge and help, but almost half still felt apprehensive and had financial barriers to adopting technology. A digitally administered exercise program especially in a group setting is a feasible option to enhance intrinsic capacity in older adults. However, more work is needed in elucidating sources of apprehension and financial barriers to adopting technology.

Objectives: We aim to determine the prevalence of vision impairment (VI) and its cumulative impact on multimorbidity, frailty, physical and cognitive function, and quality of life. Method: In all, 780 community-dwelling older adults were interviewed for demographic data and a one-off physical activity screening. Covariate measurements include vision via Snellen chart, multimorbidity, five-item FRAIL (Fatigue, Resistance, Ambulation, Illnesses, & Loss of Weight) scale and Mini-Mental State Examination (MMSE). Outcome variables taken were Barthel Index, Lawton Instrumental Activities of Daily Living (IADL) scale, grip strength, Timed Up and Go (TUG), and EuroQol 5D (EQ-5D). Results: In all, 426 (54.6%) were female, mean age was 71.3 ± 0.2 years; 240 (30.8%) had VI. The interaction between VI, multimorbidity, and frailty significantly impacts grip strength, TUG, quality of life, and IADL. Discussion: Our study is the first to look at the interaction of VI, multimorbidity, frailty, and its combined impact on key domains of intrinsic capacity. Our results further support vision screening to enable aging in place and highlight importance of screening for frailty and cognition in those with VI.

Background: With increasing cost of healthcare in our aging society, a consistent pain point is that of end-of-life care. It is particularly difficult to prognosticate in non-cancer patients, leading to more healthcare utilisation without improving quality of life. Additionally, older adults do not age homogenously. Hence, we seek to characterise healthcare utilisation in young-old and old-old at the end-of-life. Methods: We conducted a single-site retrospective review of decedents under department of Advanced Internal Medicine (AIM) over a year. Young-old is defined as 65–79 years; old-old as 80 years and above. Data collected was demographic characteristics; clinical data including Charlson Comorbidity Index (CCI), FRAIL-NH and advance care planning (ACP); healthcare utilisation including days spent in hospital, hospital admissions, length of stay of terminal admission and clinic visits; and quality of end-of-life care including investigations and symptomatic control. Documentation was individually reviewed for quality of communication. Results: One hundred eighty-nine older adult decedents. Old-old decedents were mostly females (63% vs. 42%, p = 0.004), higher CCI scores (7.7 vs 6.6, p = 0.007), similarly frail with lower polypharmacy (62.9% vs 71.9%, p = 0.01). ACP uptake was low in both, old-old 15.9% vs. young-old 17.5%. Poor prognosis was conveyed to family, though conversation did not result in moderating extent of care. Old-old had less healthcare utilisation. Adjusting for sex, multimorbidity and frailty, old-old decedents had 7.3 ± 3.5 less hospital days in their final year. Further adjusting for cognition and residence, old-old had 0.5 ± 0.3 less hospital admissions. When accounted for home care services, old-old spent 2.7 ± 0.8 less hospital days in their last admission. Conclusion: There was high healthcare utilisation in older adults, but especially young-old. Enhanced education and goal-setting are needed in the acute care setting. ACP needs to be reinforced in acute care with further research to evaluate if it reduces unnecessary utilisation at end-of-life.

Thirst is distressing but overlooked by healthcare professionals. Patients experience thirst due to comorbidities, physical or cognitive limitations, and iatrogenesis. Nasogastric tube (NGT) use and nil-by-mouth(NBM) orders are common practices that can lead to thirst. However, thirst in these populations has never been formally studied. We aim to examine prevalence of recognition and treatment of thirst among NGT + NBM and NBM patients. Our descriptive study was conducted intermittently over 25 weeks, across 1.5 years, in 12 adult general medicine wards of a tertiary hospital. Cognitively intact NGT + NBM or NBM inpatients, defined as Abbreviated Mental Test score ≥ 8, were studied. One-time questionnaire was administered. Variables included: demography, co-morbidities, clinical condition, feeding route, thirst defined by thirst distress and/or intensity ≥ 3, pain, hunger and volume status. 88 NGT + NBM and NBM patients were studied. 69.3% suffered from thirst. Thirsty patients experienced significant thirst-related distress (mean score ± SD: 5.7 ± 2.5). Subjects with previous stroke and who were euvolemic tended towards thirst. 13.6% were asked about thirst by doctors or nurses. Thirst was a major source of patient distress in our study. We suggest that thirst needs to be actively identified and targeted to achieve person-centred care.

Although age at menopause has been linked to higher risk of physical frailty in later life, little is known about other reproductive factors. Our study aimed to investigate the associations between 1) age at menarche, 2) age at natural menopause, 3) duration of reproductive period, 4) number of children, 5) use of oral contraceptives (OCP), and 6) use of hormone replacement therapy (HRT) with the risk of physical frailty in late life. We used data from 5934 women of the Singapore Chinese Health Study who experienced natural menopause, and participated in the third follow-up interviews when physical frailty was assessed. Logistic regression was used to evaluate association of reproductive factors evaluated during baseline and prior follow-up interviews with physical frailty at follow-up 3. Community-dwelling Chinese women living in Singapore. Participants had a mean age of 52.6 years at baseline (1993-1998), and a mean age of 72.8 years during the third follow-up (2014-2017). Sociodemographic characteristics, level of education, smoking history, physical activity, and history of physician-diagnosed comorbidities were collected. Participants' weight and height were self-reported. We used a modified Cardiovascular Health Study phenotype to assess physical frailty. Age at menarche was inversely associated with the likelihood of physical frailty (Ptrend = 0.001); each one-year decrease in age at menarche was associated with a 9% increase (95% CI: 4%-14%) in odds of physical frailty. Age at menopause was also inversely associated with the likelihood of physical frailty (Ptrend = 0.009); every one-year decrease in age at menopause was associated with 2% (0%-4%) increased odds. In the assessment of frailty, younger ages at menarche and menopause were associated with greater likelihood of being in the slowest quintile for timed up-and-go and weakest quintile for handgrip strength. Conversely, duration of reproductive period, parity, and use of oral contraceptives or hormone replacement therapy were not significantly associated with the likelihood of physical frailty. In our population-based cohort of Chinese women, younger ages at menarche and menopause were associated with higher likelihood of physical frailty in later life.
