Social Vulnerability, Frailty and Self-Perceived Health: Findings from The Irish Longitudinal Study on Ageing (TILDA).

BACKGROUND: Social vulnerability interacts with frailty and influences individuals' health status. Although frailty and social vulnerability are highly predictive of adverse outcomes, their relationship with self-perceived health(SPH) has been less investigated. METHODS: Data are from the Irish Longitudinal Study on Ageing(TILDA), a population-based longitudinal study of ageing. We included 4,222 participants aged ≥50 years (age 61.4±8.5 years;women 56%) from Wave 1 (2009-2011) followed over three longitudinal waves (2012,2014-2015,2016). Participants responded to single questions with five response options to rate their 1)physical health, 2)mental health, and 3)health compared to peers. 30-item Frailty (FI) and Social Vulnerability (SVI) indices were calculated using standardised methods. Multivariable regression analyses were performed to establish the association between FI and SVI cross-sectionally and longitudinally over 6 years. RESULTS: Cross-sectionally, SVI (mean:0.40±0.08; range:0.14-0.81) and FI (mean: 0.13±0.08; range:0.10-0.58) were modestly correlated (r=0.256), and independently associated with poor physical health (SVI: OR 1.43, 95%CI 1.15-1.78; FI: OR 3.16, 95%CI 2.54-3.93), poor mental health (SVI: OR 1.65, 95%CI 1.17-2.35; FI: OR 3.64, 95%CI 2.53-5.24), and poor health compared to peers (SVI: OR 1.41,95%CI 1.06-1.89; FI: OR 3.86, 95%CI 2.9-5.14). Longitudinally, FI and SVI were independently and positively associated with poor physical health (SVI: ß 1.08, 95%CI 0.76-1.39; FI: ß 1.97, 95%CI 1.58-2.36), poor mental health (SVI: ß 1.18, 95%CI 0.86-1.5; FI: ß 1.58, 95%CI 1.2-1.97), and poor overall health compared to peers (SVI: ß 0.78, 95%CI 0.89-1.33; FI: ß 1.74, 95%CI 0.47-1.1). CONCLUSIONS: In a large cohort of community-dwelling older adults, frailty and social vulnerability were associated with poor SPH and with risk of SPH decline over six years.

The Syncope-Falls Index: a tool for predicting risk of syncope and complex falls in the older adult based on cumulative health deficits.

BACKGROUND: Syncope is aetiologically diverse and associated with adverse outcomes; in older people, there is clinical overlap with complex falls presentations (i.e. recurrent, unexplained and/or injurious). AIM: To formulate an index to predict future risk of syncope and falls in the Irish longitudinal study on ageing (TILDA). DESIGN/METHODS: Using the frailty index methodology, we selected, from TILDA Wave 1 (2010), 40 deficits that might increase risk of syncope and falls. This syncope-falls index (SYFI) was applied to TILDA Wave 1 participants aged 65 and over, who were divided into three risk groups (low, intermediate and high) based on SYFI tertiles. Multivariate logistic regression models were used to investigate, controlling for age and sex, how SYFI groups predicted incident syncope, complex falls and simple falls occurring up to Wave 4 of the study (2016). RESULTS: At Wave 1, there were 3499 participants (mean age 73, 53% women). By Wave 4, of the remaining 2907 participants, 185 (6.4%) had reported new syncope, 1077 (37.0%) complex falls and 218 (7.5%) simple falls. The risk of both syncope and complex falls increased along the SYFI groups (high risk group: odds ratio 1.88 [1.26-2.80], P = 0.002 for syncope; 2.22 [1.82-2.72], P < 0.001 for complex falls). No significant relationship was identified between SYFI and simple falls. CONCLUSION: The 6-year incidences of falls and syncope were high in this cohort. SYFI could help identify older adults at risk of syncope and complex falls, and thus facilitate early referral to specialist clinics to improve outcomes.

Physical and mental health of older people while cocooning during the COVID-19 pandemic.

BACKGROUND: Cocooning or shielding, i.e. staying at home and reducing face-to-face interaction with other people, was an important part of the response to the COVID-19 pandemic for older people. However, concerns exist regarding the long-term adverse effects cocooning may have on their physical and mental health. AIM: To examine health trajectories and healthcare utilization while cocooning in a cohort of community-dwelling people aged ≥70 years. DESIGN: Survey of 150 patients (55% female, mean age 80 years and mean Clinical Frailty Scale Score 4.8) attending ambulatory medical services in a large urban university hospital. METHODS: The survey covered four broad themes: access to healthcare services, mental health, physical health and attitudes to COVID-19 restrictions. Survey data were presented descriptively. RESULTS: Almost 40% (59/150) reported that their mental health was 'worse' or 'much worse' while cocooning, while over 40% (63/150) reported a decline in their physical health. Almost 70% (104/150) reported exercising less frequently or not exercising at all. Over 57% (86/150) of participants reported loneliness with 1 in 8 (19/150) reporting that they were lonely 'very often'. Half of participants (75/150) reported a decline in their quality of life. Over 60% (91/150) agreed with government advice for those ≥70 years but over 40% (61/150) reported that they disliked the term 'cocooning'. CONCLUSIONS: Given the likelihood of further restrictions in coming months, clear policies and advice for older people around strategies to maintain social engagement, manage loneliness and continue physical activity and access timely medical care and rehabilitation services should be a priority.

Lack of association between angiotensin-converting enzyme genotype and muscle strength in Peruvian older people.

Aging can be associated with decreasing muscle strength, and related factors are comorbidities, sex, physical activity, and possibly genetic factors. Among genetic factors the renin-angiotensin system is of interest, but data on the Peruvian population is lacking. The objective of our study was to evaluate the association of grip strength and angiotensin convertase enzyme (ACE) polymorphism in Peruvian older people. A cross-sectional study in a convenience sample of 104 participants over 60 years in Lima, Perú, with analysis of the ACE polymorphism, was performed. We studied 104 participants, 46 men (44,2%) and 58 women (55,8%), with a mean age and standard deviation (SD) of 73,7 (7,4) years, range between 60-90 years. The frequency of D/D, I/D and I/I genotypes was 12,7; 43,7 and 43,7% respectively. The genotype distribution of ACE polymorphism agreed with the Hardy-Weinberg equilibrium (p=0,746). The mean (SD) of grip strength in the D/D, I/D and I/I polymorphisms were 24,8 (7,2); 22,8 (7,2) and 23,4 (7,6) kg respectively; no significant difference was observed (p=0,41) between genetic groups. In this small convenience sample of older Peruvians, no association was found between grip strength and ACE genotype.

Care home residents admitted to hospital through the emergency pathway: characteristics and associations with inpatient mortality.

BACKGROUND: Routinely collected hospital information could help to understand the characteristics and outcomes of care home residents admitted to hospital as an emergency. METHODS: This retrospective 2-year service evaluation included first emergency admissions of any older adult (≥75 years) presenting to Cambridge University Hospital. Routinely collected patient variables were captured by an electronic patient record system. Care home status was established using an official register of care homes. RESULTS: 7.7% of 14,777 admissions were care home residents. They were older, frailer, more likely to be women and have cognitive impairment than those admitted from their own homes. Additionally, 42% presented with an Emergency Department Modified Early Warning Score above the threshold triggering urgent review, compared to 26% of older adults from their own homes. Admission from a care home was associated with higher 30-day inpatient mortality (11.1 vs 5.7%), which persisted after multivariable adjustment (hazard ratio: 1.42; 95% confidence interval: 1.09-1.83; p = 0.008). CONCLUSION: Care home residents admitted to hospital as an emergency have high illness acuity and inpatient mortality.

The Clinical Frailty Scale predicts inpatient mortality in older hospitalised patients with idiopathic Parkinson's disease.

Parkinson's disease and frailty are both common conditions affecting older people. Little is known regarding the association of the Clinical Frailty Scale with hospital outcomes in idiopathic Parkinson's disease patients admitted to the acute hospital. We aimed to test whether frailty status was an independent predictor of short-term mortality and other hospital outcomes in older inpatients with idiopathic Parkinson's disease. METHOD: We conducted an observational retrospective study in a large tertiary university hospital between October 2014 and October 2016. Routinely measured patient characteristics included demographics (age and sex), Clinical Frailty Scale, acute illness severity (Emergency Department Modified Early Warning Score), the Charlson Comorbidity Index, discharge specialty, history of dementia, history of depression and the presence of a new cognitive impairment. Outcomes studied were inpatient mortality, death within 30 days of discharge, new institutionalisation, length of stay ≥ 7 days and readmission within 30 days to the same hospital. RESULTS: There were 393 first admission episodes of idiopathic Parkinson's disease patients aged 75 years or more; 166 (42.2%) were female. The mean age (standard deviation) was 82.8 (5.0) years. The mean Clinical Frailty Scale was 5.9 (1.4) and the mean Charlson Comorbidity Index was 1.3 (1.5). After adjustment for covariates, frailty and acute illness severity were independent predictors of inpatient mortality; odds ratio for severely/very severely frail or terminally ill = 8.1, 95% confidence interval 1.0-63.5, p = 0.045 and odds ratio for acute illness severity: 1.3, 95% confidence interval 1.1-1.6, p = 0.005). The Clinical Frailty Scale did not significantly predict other hospital outcomes. CONCLUSIONS: The Clinical Frailty Scale was a significant predictor of inpatient mortality in idiopathic Parkinson's disease patients admitted to the acute hospital and it may be useful as a marker of risk in this vulnerable population.

Anticholinergic medications in patients admitted with cognitive impairment or falls (AMiCI). The impact of hospital admission on anticholinergic cognitive medication burden. Results of a multicentre observational study.

WHAT IS KNOWN AND OBJECTIVE: Drugs with anticholinergic properties increase the risk of falls, delirium, chronic cognitive impairment, and mortality and counteract procholinergic medications used in the treatment of dementia. Medication review and optimisation to reduce anticholinergic burden in patients at risk is recommended by specialist bodies. Little is known how effective this review is in patients who present acutely and how often drugs with anticholinergic properties are used temporarily during an admission. The aim of the study was to describe the changes in the anticholinergic cognitive burden (ACB) in patients admitted to hospital with a diagnosis of delirium, chronic cognitive impairment or falls and to look at the temporary use of anticholinergic medications during hospital stay. METHODS: This is a multi-centre observational study that was conducted in seven different hospitals in the UK, Finland, The Netherlands and Italy. RESULTS AND DISCUSSION: 21.1% of patients had their ACB score reduced by a mean of 1.7%, 19.7% had their ACB increased by a mean of 1.6%, 22.8% of DAP naïve patients were discharged on anticholinergic medications. There was no change in the ACB scores in 59.2% of patients. 54.1% of patients on procholinergics were taking anticholinergics. Out of the 98 medications on the ACB scale, only 56 were seen. Medications with a low individual burden were accounting for 64.9% of the total burden. Anticholinergic drugs were used temporarily during the admission in 21.9% of all patients. A higher number of DAPs used temporarily during admission was associated with a higher risk of ACB score increase on discharge (OR = 1.82, 95% CI for OR: 1.36-2.45, P < .001). WHAT IS NEW AND CONCLUSION: There was no reduction in anticholinergic cognitive burden during the acute admissions. This was the same for all diagnostic subgroups. The anticholinergic load was predominantly caused by medications with a low individual burden. More than 1 in 5 patients not taking anticholinergics on admission were discharged on them and similar numbers saw temporary use of these medications during their admission. More than half of patients on cholinesterase-inhibitors were taking anticholinergics at the same time on admission, potentially directly counteracting their effects.

Social Determinants of Discharge Outcomes in Older People Admitted to a Geriatric Medicine Ward.

The factors determining hospital discharge outcomes in older people are complex. This retrospective study was carried out in an in-patient geriatric ward over a month in 2015 and aimed to explore if self-reported feeling of loneliness and clinical frailty contribute to longer hospital stays or higher rates of readmission to hospital after discharge in the older population. Twenty-two men and twenty-five women (mean age 85.1 years) were assessed. There was a significant multivariate association between both self-reported loneliness (p=0.021) and the Clinical Frailty Scale (p=0.010) with length of stay, after adjusting for age, dementia and living alone. In multivariate analysis, patients who lived alone were more likely to be readmitted to hospital within 30 days (p=0.036). Loneliness, living alone and clinical frailty were associated with adverse discharge outcomes. Lower thresholds for referral to voluntary organisations and for psychosocial interventions in patients who report loneliness or live alone may be beneficial.

Higher Physiotherapy Frequency Is Associated with Shorter Length of Stay and Greater Functional Recovery in Hospitalized Frail Older Adults: A Retrospective Observational Study.

Extra physiotherapy has been associated with better outcomes in hospitalized patients, but this remains an under-researched area in geriatric medicine wards. We retrospectively studied the association between average physiotherapy frequency and outcomes in hospitalized geriatric patients. High frequency physiotherapy (HFP) was defined as ≥0.5 contacts/day. Of 358 eligible patients, 131 (36.6%) received low, and 227 (63.4%) HFP. Functional improvement (discharge versus admission) in the modified Rankin scale was greater in the HFP group (1.1 versus 0.7 points, P<0.001). The mean length of stay (LOS) of the HFP group was 6 days shorter (7 versus 13 days, P<0.001). After adjusting for age, gender, comorbidity (Charlson index), frailty (Clinical Frailty Scale), dementia and acute illness severity, HFP was an independent predictor of functional improvement, shorter LOS and likelihood of being discharged without a formal care package. Prospective research is needed to examine the effect of physiotherapy frequency and intensity in geriatric wards.

Association of the clinical frailty scale with hospital outcomes.

BACKGROUND: The clinical frailty scale (CFS) was validated as a predictor of adverse outcomes in community-dwelling older people. In our hospital, the use of the CFS in emergency admissions of people aged ≥ 75 years was introduced under the Commissioning for Quality and Innovation payment framework. AIM: We retrospectively studied the association of the CFS with patient characteristics and outcomes. DESIGN: Retrospective observational study in a large tertiary university National Health Service hospital in UK. METHODS: The CFS was correlated with transfer to specialist Geriatric ward, length of stay (LOS), in-patient mortality and 30-day readmission rate. RESULTS: Between 1st August 2013 and 31st July 2014, there were 11 271 emergency admission episodes of people aged ≥ 75 years (all specialties), corresponding to 7532 unique patients (first admissions); of those, 5764 had the CFS measured by the admitting team (81% of them within 72 hr of admission). After adjustment for age, gender, Charlson comorbidity index and history of dementia and/or current cognitive concern, the CFS was an independent predictor of in-patient mortality [odds ratio (OR) = 1.60, 95% confidence interval (CI): 1.48 to 1.74, P < 0.001], transfer to Geriatric ward (OR = 1.33, 95% CI: 1.24 to 1.42, P < 0.001) and LOS ≥ 10 days (OR = 1.19, 95% CI: 1.14 to 1.23, P < 0.001). The CFS was not a multivariate predictor of 30-day readmission. CONCLUSIONS: The CFS may help predict in-patient mortality and target specialist geriatric resources within the hospital. Usual hospital metrics such as mortality and LOS should take into account measurable patient complexity.

Characteristics and outcomes of older persons attending the emergency department: a retrospective cohort study.

BACKGROUND: The analysis of routinely collected hospital data informs the design of specialist services for at-risk older people. AIM: Describe the outcomes of a cohort of older emergency department (ED) attendees and identify predictors of these outcomes. DESIGN: retrospective cohort study. METHODS: All patients aged 65 years or older attending an urban university hospital ED in January 2012 were included (N = 550). Outcomes were retrospectively followed for 12 months. Statistical analyses were based on multivariate binary logistic regression models and classification trees. RESULTS: Of N = 550, 40.5% spent ≤6 h in the ED, but the proportion was 22.4% among those older than 81 years and not presenting with musculoskeletal problems/fractures. N = 349 (63.5%) were admitted from the ED. A significant multivariate predictor of in-hospital mortality was Charlson comorbidity index [CCI; odds ratio = 1.19, 95% confidence interval: 1.07, 1.34, P = 0.002]. Among patients who were discharged from ED without admission or after their first in-patient admission (N = 499), 232 (46.5%) re-attended ED within 1 year, with CCI being the best predictor of re-attendance (CCI ≤ 4: 25.8%, CCI > 5: 60.4%). Among N = 499, 34 (6.8%) had died after 1 year of initial ED presentation. The subgroup (N = 114) with the highest mortality (17.5%) was composed by those aged >77 years and brought in by ambulance on initial presentation. CONCLUSIONS: Advanced age and comorbidity are important drivers of outcomes among older ED attendees. There is a need to embed specialist geriatric services within frontline services to make them more gerontologically attuned. Our results predate the opening of an acute medical unit with specialist geriatric input.

A Risk Index for Geriatric Acute Medical Admissions (RIGAMA).

AIM: to create and validate a Risk Index for Geriatric Acute Medical Admissions (RIGAMA) for those aged ≥ 65, based on accumulation of deficits. METHODS: we retrospectively validated a 30-item RIGAMA against inpatient mortality, length of stay (LOS), discharge to long-term care (LTC) and 30-day readmission, adjusted for age. RESULTS: ≥ 1 RIGAMA deficit was superior to age in predicting mortality and prolonged LOS, with a clear incremental effect. The latter was true for ≥3 deficits in predicting 30-day readmission. Three to 5 deficits predicted discharge to LTC better than age. CONCLUSIONS: RIGAMA is easy to collect by the admitting junior doctor and may help trigger early senior support and inform the appropriate use of hospital resources by older patients.

The Impact of Frailty on Post-Acute Rehabilitation Outcomes in Older Adults.

UNLABELLED: Objective, Design, Measurements: We assessed the correlations of the Frailty Instrument for primary care of the Survey of Health, Ageing and Retirement in Europe (SHARE-FI on admission: non-frail, pre-frail, frail) with the outcomes of a Short-term Post-Acute Rehabilitative Care programme (N=172 admissions over one-year period, 95 of which were frail). RESULTS: SHARE-FI correlated with age (non-frail: mean 79.2 years; frail: 83.6; P<0.001). Adjusting for age, SHARE-FI correlated with longer length of stay (non-frail: median 30 days; frail: 42; P=0.047), higher rate of emergency transfer to acute hospital (non-frail: 2.4%; frail: 21.1%; P=0.004), and lower home discharge rate (non-frail: 97.6%; frail: 81.9%; P=0.009). While frailty correlated with more disability on admission and discharge, there was no statistically significant difference in Barthel Index (BI) improvement across frailty categories (all groups had median BI improvement of ≥2 points, P=0.247). CONCLUSION: The post-acute rehabilitation of the frail is worthwhile but requires more time and access to acute hospital facilities.

The Role the Frailty Syndrome Can Play in Advocacy and Resource Allocation for Our Ageing Population - Findings in a Dublin Day Hospital.

Frail individuals are at higher risk of adverse outcomes, and need identification and priority access to Comprehensive Geriatric Assessment (CGA). We prospectively collected data on new referrals to our day hospital. Levels of frailty were measured with the SHARE Frailty Instrument for Primary Care (SHARE-FI). Of 257 patients assessed (90 men, 167 women), 110 (43%) were non-frail, 66 (26%) pre-frail and 81 (32%) frail. Mean age was 82 years for the non-frail, 83 for the pre-frail and 84 for the frail. Forty-one percent of the frail reported two or more falls in the preceding year, compared to 38% of the pre-frail and 21% of the non-frail (P for trend = 0.003). Of 27 patients who were referred for ongoing multidisciplinary assessment and rehabilitation, 16 (59%) were frail. The frailty syndrome has the potential to become an advocacy tool for older people and help target effective, but finite, CGA resources.

Deprivation in cold weather increases the risk of hospital admission with hypothermia in older people.

BACKGROUND: Material deprivation in cold weather may increase the risk of hypothermia and contribute to excess winter mortality. To date, there were no local data to support the potential contribution of material deprivation to the incidence of hypothermia in Irish older people. AIM: To contribute evidence from a hospital-based perspective. METHODS: Patient series from St James's Hospital Dublin, Ireland. Of all patients aged≥65 years experiencing their last medical admission between 1 January 2002 and 31 December 2010, we selected those who presented with a body temperature of <35 °C. Their clinical characteristics were compared with those of a random sample of 200 age and gender-matched non-hypothermic patients. Multivariate logistic regression was used to identify predictors of presentation with hypothermia. The following predictors were considered: age, gender, mean air temperature on the day of admission, year of admission, comorbidity, major diagnostic categories, and material deprivation as per the Irish National Deprivation Index (NDI). RESULTS: Eighty patients presented with hypothermia over the period. They presented in colder days (mean 8.8 vs. 10.8 °C, P<0.001) were less likely to present in summer (P<0.002), more likely to present in winter (P=0.010), and their mortality was high (50 vs. 17%, P<0.001). The interaction NDI* air temperature was a significant multivariate predictor of hypothermia (OR=1.03, 95% CI 1.01-1.06, P=0.033). CONCLUSIONS: The NDI could be an adequate tool to target fuel poverty in older people.

Profiling the medical admissions of the homeless.

AIM: to describe the characteristics and outcomes of homeless people admitted to our Internal Medicine service in St. James's Hospital, Dublin (Ireland), between 2002 and 2011. METHODS: we interrogated an anonymized in-patient database. RESULTS: there were 1,460 homeless admissions (623 unique patients; 39% admitted more than once). Most patients were young, male, and had low comorbidity levels. Thirty-seven percent of the admissions were alcohol-related and 27% substance abuse-related. Thirteen percent had an active psychiatric illness. Their in-patient mortality rate was 5%. Seventy-two percent were discharged without the residential arrangement being explicitly documented, 15% self-discharged or absconded, and 8% were discharged to a residential facility. CONCLUSION: results are novel in our context and will be relevant for local policy and practice.

Psychosocial and functional correlates of nutrition among community-dwelling older adults in Ireland.

OBJECTIVES: To examine psychosocial and functional correlates of nutrition in a nonrandom sample of Irish community-dwelling older adults. DESIGN: Cross-sectional observational study. SETTING: Technology Research for Independent Living (TRIL) Clinic, a comprehensive geriatric assessment facility in St James's Hospital, Dublin. Data were collected from participants by medical personnel (physical assessments) and psychologists (questionnaires), between August 2007 and May 2009. PARTICIPANTS: 556 participants (388 females; 168 males) ranging in age from 60-92 years (Mean 72.5 years, SD 7.1). All were community-dwelling and provided informed consent. MEASUREMENTS: The Nestlé Mini-Nutritional Assessment (MNA®), Time to get up and go (TUG) and the Lubben Social Network Scale-18 (LSNS-18) were used to assess nutrition, functional mobility and social support. METHODS: Multivariate binary logistic regression was used to examine the association between social support or mobility and nutritional status, whilst controlling for possible confounders (age, gender, living alone and material deprivation). RESULTS: The strongest predictors of abnormal nutritional status were mobility (p < 0.001) and social support (p = 0.005). Other significant predictors of nutritional risk were age (p = 0.032) and deprivation (p = 0.018). CONCLUSION: The results emphasise the importance of mobility and social supports in mediating nutritional outcomes in Irish community-dwelling older adults.
