Delirium is significantly associated with hospital frailty risk score derived from administrative data.

OBJECTIVES: Delirium is highly prevalent in hospitalised older adults, under-diagnosed and associated with poor outcomes. We aim to determine (i) association of frailty measured using Hospital Frailty Risk Score (HFRS) with delirium, (ii) impact of delirium on mortality, 30-days readmission, extended length of stay (eLOS) and cost (eCOST). METHODS: Retrospective cohort study was conducted on 902 older adults ≥75 years discharged from an academic tertiary hospital between March and September 2021. Data was obtained from hospital administrative database. RESULTS: Delirium was prevalent in 39.1%, 58.1% were female with mean age 85.3 ± 6.2 years. Patients with delirium were significantly older, had higher HFRS, pneumonia, urinary tract infection (UTI), E.coli and Klebsiella infection, constipation, dehydration, stroke and intracranial bleed, with comorbidities including dementia, diabetes, hypertension, hyperlipidaemia and chronic kidney disease. In-hospital mortality, 30-days mortality, 30-days readmission, median LOS and cost was significantly higher. Delirium was significantly associated with at least intermediate frailty (OR = 3.52; CI = 2.48-4.98), dementia (OR = 2.39; CI = 1.61-3.54), UTI (OR = 1.95; CI = 1.29-2.95), constipation (OR = 2.49; CI = 1.43-4.33), Klebsiella infection (OR = 3.06; CI = 1.28-7.30), dehydration (OR = 2.01; CI = 1.40 - 2.88), 30-day mortality (OR = 2.52; CI = 1.42-4.47), 30-day readmission (OR = 2.18; CI = 1.36-3.48), eLOS (OR = 1.80; CI = 1.30-2.49) and eCOST (OR = 1.67; CI = 1.20-2.35). CONCLUSIONS: Delirium was highly prevalent in older inpatients, and associated with dementia, frailty, increased cost, LOS, 30-day readmissions and mortality. Hospital Frailty Risk Score had robust association with delirium and can be auto-populated from electronic medical records. Prospective studies are needed on multicomponent delirium preventive measures in high-risk groups identified by HFRS in acute care settings.

Outcomes of Care by Geriatricians and Non-geriatricians in an Academic Hospital.

Introduction: While hospitalist and internist inpatient care models dominate the landscape in many countries, geriatricians and internists are at the frontlines managing hospitalized older adults in countries such as Singapore and the United Kingdom. The primary aim of this study was to determine outcomes for older patients cared for by geriatricians compared with non-geriatrician-led care teams. Materials and Methods: A retrospective cohort study of 1,486 Internal Medicine patients aged ≥75 years admitted between April and September 2021 was conducted. They were either under geriatrician or non-geriatrician (internists or specialty physicians) care. Data on demographics, primary diagnosis, comorbidities, mortality, readmission rate, Hospital Frailty Risk Score (HFRS), Age-adjusted Charlson Comorbidity Index, Length of Stay (LOS), and cost of hospital stay were obtained from the hospital database and analyzed. Results: The mean age of patients was 84.0 ± 6.3 years, 860 (57.9%) females, 1,183 (79.6%) of Chinese ethnicity, and 902 (60.7%) under the care of geriatricians. Patients under geriatrician were significantly older and had a higher prevalence of frailty, dementia, and stroke, whereas patients under non-geriatrician had a higher prevalence of diabetes and hypertension. Delirium as the primary diagnosis was significantly higher among patients under geriatrician care. Geriatrician-led care model was associated with shorter LOS, lower cost, similar inpatient mortality, and 30-day readmission rates. LOS and cost were lower for patients under geriatrician care regardless of frailty status but significant only for low and intermediate frailty groups. Geriatrician-led care was associated with significantly lower extended hospital stay (OR 0.73; 95% CI 0.56-0.95) and extended cost (OR 0.69; 95% CI 0.54-0.95). Conclusion: Geriatrician-led care model showed shorter LOS, lower cost, and was associated with lower odds of extended LOS and cost.

Motoric cognitive risk syndrome, physio-cognitive decline syndrome, cognitive frailty and reversibility with dual-task exercise.

INTRODUCTION: Cognitive frailty (CF) is associated with dementia and disability. It was initially proposed in 2013 by the International Institute of Nutrition and Aging and the International Geriatrics Association. Over the years, there have been many emerging definitions e.g., Motoric Cognitive Risk Syndrome (MCR), Physio-cognitive Decline Syndrome (PCDS), reversible CF and potentially reversible CF. OBJECTIVE: Our objective was to determine the demographics including physical, functional, and psychosocial factors for the four CF definitions amongst community-dwelling older adults. In addition, the effect of dual-task exercise on the reversibility of different definitions of CF was also studied. METHODS: Participants were community-dwelling older adults aged ≥60 years recruited between August 2017 and December 2019. Older adults screened to be frail, prefrail or have cognitive impairment were invited to participate in dual-task exercise program called HAPPY (Healthy Ageing Promotion Program for You). Improvement in cognition, frailty, and physical performance after a 3-month dual-task exercise intervention program was compared with controls. RESULTS: The prevalence of CF depending on definition ranged from 8.8% to 28.7% with minimal overlap. The cognitive scores were significantly lower in all the groups predominantly affecting non-memory domains except for reversible CF. Frailty was three to seven times more prevalent in CF. MCR group had higher prevalence of functional limitation, pain and depression. All four groups had significant increase in global cognition scores especially in the attention domain where the control group declined, and reduction in the prevalence of frailty post intervention. MCR and reversible CF were significantly associated with increased odds of cognitive improvement after 3 months of intervention compared with control. CONCLUSION: CF is a novel concept and regardless of the definitions, is a target for reversing frailty, functional limitation and cognitive impairment through dual-task exercise. Long-term prospective studies are needed to evaluate the effectiveness of dual-task interventions in delaying the conversion to dementia and reduction of disability.

Relationship of Fat Mass Index and Fat Free Mass Index With Body Mass Index and Association With Function, Cognition and Sarcopenia in Pre-Frail Older Adults.

Background: Body mass index (BMI) is an inadequate marker of obesity, and cannot distinguish between fat mass, fat free mass and distribution of adipose tissue. The purpose of this study was twofold. First, to assess cross-sectional relationship of BMI with fat mass index (FMI), fat free mass index (FFMI) and ratio of fat mass to fat free mass (FM/FFM). Second, to study the association of FMI, FFMI and FM/FFM with physical function including sarcopenia, and cognition in pre-frail older adults. Methods: Cross-sectional study of 191 pre-frail participants ≥ 65 years, 57.1% females. Data was collected on demographics, cognition [Montreal Cognitive Assessment (MoCA)], function, frailty, calf circumference, handgrip strength (HGS), short physical performance battery (SPPB) and gait speed. Body composition was measured using InBody S10. FMI, FFMI and FM/FFM were classified into tertiles (T1, T2, T3) with T1 classified as lowest and T3 highest tertile respectively and stratified by BMI. Results: Higher FFMI and lower FM/FFM in the high BMI group were associated with better functional outcomes. Prevalence of low muscle mass was higher in the normal BMI group. FMI and FM/FFM were significantly higher in females and FFMI in males with significant gender differences except for FFMI in ≥ 80 years old. Small calf circumference was significantly less prevalent in the highest tertile of FMI, FM/FMI and FFMI. Prevalence of sarcopenic obesity and low physical function (HGS, gait speed and SPPB scores) were significantly higher in the highest FMI and FM/FFM tertile. Highest FFMI tertile group had higher physical function, higher MoCA scores, lower prevalence of sarcopenic obesity and sarcopenia, After adjustment, highest tertile of FFMI was associated with lower odds of sarcopenia especially in the high BMI group. Highest tertile of FM/FFM was associated with higher odds of sarcopenia. Higher BMI was associated with lower odds of sarcopenia. Conclusion: FFMI and FM/FFM may be a better predictor of functional outcomes in pre-frail older adults than BMI. Cut-off values for healthy BMI values and role of calf circumference as a screening tool for sarcopenia need to be validated in larger population. Health promotion intervention should focus on FFMI increment.

Relationship Between Fear of Falling, Fear-Related Activity Restriction, Frailty, and Sarcopenia.

OBJECTIVES: To determine the prevalence of fear of falling (FOF) and fear-related activity restriction (FAR) and their association with frailty, sarcopenia, gait speed and grip strength, cognitive impairment, depression, social isolation, self-perceived health, and vision. DESIGN: Observational cross-sectional study. SETTING: Community. PARTICIPANTS: A total of 493 community-dwelling older adults, 60 years and older. MEASURES: FOF and FAR were assessed using validated single closed-ended questions. Questionnaire was administered to evaluate frailty (FRAIL scale - Fatigue, Resistance, Aerobic, Illness, and Loss of Weight), sarcopenia (SARC-F - lifting and carrying 10 pounds, walking across a room, transferring from bed/chair, climbing a flight of 10 stairs, and frequency of falls in the past 1 year), social isolation (six-item Lubben Social Network Scale), depression (Even Briefer Assessment Scale), cognition (Chinese Mini-Mental State Examination), and perceived general health and pain (The EuroQol-5 Dimension (EQ-5D)and EQ visual analogue scale (EQ VAS)) . Binary logistic regression was performed to determine the influence of sociodemographic, medical, functional, and cognitive variables on FOF with/without FAR. RESULTS: Prevalence of FOF was 69.2%, and among them, 38.4% had FAR. Prevalence of FOF with or without FAR in those with sarcopenia was 93.3% and in prefrail/frail was 76.6%. FOF was significantly associated with prefrail/frail (odds ratio (OR) = 2.17; 95% confidence interval (CI) = 1.26-3.73), depression (OR = 4.90; 95% CI = 1.06-22.67), number of medications (OR = 1.28; 95% CI = 1.03-1.59), and female sex (OR = 3.54; 95% CI = 1.82-6.90). FOF + FAR was associated with depression (OR = 5.17; 95% CI = 1.84-14.54) and sarcopenia (OR = 8.13; 95% CI = 1.52-43.41). CONCLUSION: FOF with/without FAR is highly prevalent among community-dwelling older adults, especially in those with sarcopenia, prefrailty, and frailty, with significant negative impact on function, quality of life, social network, and mental health. Further research is needed to investigate the value of population-level screening, causal relationship, and efficacy of comprehensive intervention strategies.

Rapid Geriatric Assessment Using Mobile App in Primary Care: Prevalence of Geriatric Syndromes and Review of Its Feasibility.

With the aging population and consequent increase in associated prevalence of frailty, dementia, and multimorbidity, primary care physicians will be overwhelmed with the complexity of the psychosocial and clinical presentation. Geriatric syndromes including frailty, sarcopenia, cognitive impairment, and anorexia of aging (AA) either in isolation or in combination are associated with an increased risk of adverse outcomes and if recognized early, and appropriately managed, will lead to decreased disability. Primary care practices are often located in residential settings and are in an ideal position to incorporate preventive screening and geriatric assessment with personalized management. However, primary care physicians lack the time, multidisciplinary resources, or skills to conduct geriatric assessment, and the limited number of geriatricians worldwide further complicates the matter. There is no one effective strategy to implement geriatric assessment in primary care which is rapid, cost-effective, and do not require geriatricians. Rapid Geriatric Assessment (RGA) takes <5 min to complete. It screens for frailty, sarcopenia, AA, and cognition with assisted management pathway without the need of a geriatrician. We developed RGA iPad application for screening with assisted management in two primary care practices and explored the feasibility and overall prevalence of frailty, sarcopenia, and AA. The assessment was conducted by trained nurses and coordinators. Among 2,589 older patients ≥65 years old, the prevalence of frailty was 5.9%, pre-frail 31.2%, and robust 62.9%. Fatigue was present in 17.8%, and among them, the prevalence of undiagnosed depression as assessed by the Patient Health Questionnaire (PHQ)-9 was 76.4% and 13.5% of total. The prevalence of sarcopenia was 15.4%, and 13.9% experienced at least one fall in the past year. AA was prevalent in 10.9%. The time taken to do the assessment with defined algorithm was on average 5 min or less per patient, and 96% managed to complete the assessment prior to seeing their doctor in the same session. The RGA app is a rapid and feasible tool to be used by any healthcare professional in primary care for identification of geriatric syndrome with assisted management.

Retrospective evaluation of healthcare utilisation and mortality of two post-discharge care programmes in Singapore.

OBJECTIVE: To evaluate the impact on healthcare utilisation frequencies and charges, and mortality of a programme for frequent hospital utilisers and a programme for patients requiring high acuity post-discharge care as part of an integrated healthcare model. DESIGN: A retrospective quasi-experimental study without randomisation where patients who received post-discharge care interventions were matched 1:1 with unenrolled patients as controls. SETTING: The National University Health System (NUHS) Regional Health System (RHS), which was one of six RHS in Singapore, implemented the NUHS RHS Integrated Interventions and Care Extension (NICE) programme for frequent hospital utilisers and the NUHS Transitional Care Programme (NUHS TCP) for high acuity post-discharge care. The programmes were supported by the Ministry of Health in Singapore, which is a city-state nation located in Southeast Asia with a 5.6 million population. PARTICIPANTS: Linked healthcare administrative data, for the time period of January 2013 to December 2016, were extracted for patients enrolled in NICE (n=554) or NUHS TCP (n=270) from June 2014 to December 2015, and control patients. INTERVENTIONS: For both programmes, teams conducted follow-up home visits and phone calls to monitor and manage patients' post-discharge. PRIMARY OUTCOME MEASURES: One-year pre- and post-enrolment healthcare utilisation frequencies and charges of all-cause inpatient admissions, emergency admissions, emergency department attendances, specialist outpatient clinic (SOC) attendances, total inpatient length of stay and mortality rates were compared. RESULTS: Patients in NICE had lower mortality rate, but higher all-cause inpatient admission, emergency admission and emergency department attendance charges. Patients in NUHS TCP did not have lower mortality rate, but had higher emergency admission and SOC attendance charges. CONCLUSIONS: Both NICE and NUHS TCP had no improvements in 1 year healthcare utilisation across various setting and metrics. Singular interventions might not be as impactful in effecting utilisation without an overhauling transformation and restructuring of the hospital and healthcare system.

[National University Health System (NUHS) Transitional Care Program].

Frail elderly patients require a longer time to recuperate after hospitalization, and are often discharged home from the hospital with little support despite their needs fpr complex care. They are particularly vulnerable to hazards of hospitalization and fragmented care if not appropriately managed. A geriatrician-led transitional care program called NUH-to-Home (NUH2H) was started in March 2014 to provide high-quality person-centered interdisciplinary care for older adults who were discharged from the National University Hospital (NUH) Singapore. It aims to enhance the quality and safety of post-discharge care at home, leading to an eventual reduction in readmissions and prolonged hospital stay. In the first year of implementation, there was a 67%. 68% and 75% reduction in readmissions, emergency room visits and length of hospital stay respectively.
