Managing pre-frailty and frailty is crucial for maintaining the health and independence of older adults. Through “Systemic Approach to Frailty with a Focus on Pre-Frailty for Healthy and High-Quality Aging” project, Slovenia is establishing a systematic approach to identify and address frailty, while developing solutions to support preventive measures across healthcare and community levels. Key steps include integrating health and social care systems, strengthening health literacy, adapting and co-creating healthy living environments through a community-based approach and social participation, all essential for promoting healthier and higher-quality aging in the population.
This paper outlines the innovative conceptual and methodological approach to project development and its anticipated outcomes.

Show summaryHide summary
BaCKGROUND: The social domain of frailty is often poorly defined or missing from measures of frailty. The literature is still inconclusive on the nature and scope of social frailty, although studies indicate that it has a substantial impact on disability and mortality outcomes.
AIMS: This Umbrella Review aimed to synthesise concepts and measures of social frailty.
METHODS: A search for reviews was performed in Web of Science, CINAHL, SOCINDEX, Medline, PsychoINFO and COSMIN databases. This Umbrella Review was conducted and reported with reference to the Joanna Briggs Institute (JBI) Reviewer’s Manual. The JBI Critical Appraisal Checklist for Systematic Review was used to assess the quality of studies.
RESULTS: Sixteen reviews were included. The concept of social frailty was summarised as weakness in a person’s social infrastructure compounded by a declining ability to change their circumstances. Forty-two measures of social frailty were identified which included a total of 228 items relating to social frailty. These were grouped into nine domains, of which participation in social activities was most commonly included within measures.
CONCLUSIONS: The use of diverse indicators creates a challenge for the measurement of social frailty. Their limited use in health and social care practice undermines the practical utility of the concept. This review helps to provide conceptual clarity and a platform for the development and validation of a robust social frailty measure which will facilitate the identification of people at risk and target interventions to prevent or alleviate the impact of social frailty on older people.

Show summaryHide summary
BACKGROUND: Knee osteoarthritis is a common disease that causes disability and loss of independence in middle-aged and older adults, and may interact with frailty through shared pathways. Understanding their bidirectional relationship is clinically meaningful for early intervention. This study aimed to investigate the associations between knee osteoarthritis and frailty among middle-aged and older adults in China.
METHODS: The data for this study came from three waves (baseline 2011, follow-up 2013 and 2015) of the China Health and Retirement Longitudinal Study (CHARLS). A total of 3560 participants were included. Frailty was assessed with the Frailty Index. Knee osteoarthritis was defined as physician-diagnosed arthritis with self-reported knee pain. Longitudinal bidirectional relationships were found using cross-lagged panel models and random-intercept cross-lagged panel models.
RESULTS: A longitudinal bidirectional relationship between knee osteoarthritis and frailty was observed, with a stronger effect of frailty on subsequent knee osteoarthritis (Wald χ² = 11.416, P < 0.001). At the between-person level, individuals with knee osteoarthritis also tend to have a higher risk of frailty (β= 0.454, P < 0.001). At the within-person level, the predictive effect of knee osteoarthritis on frailty was significant only in the long term (β=0.055, P < 0.05). Subgroup analyses showed that this longitudinal bidirectional relationship was particularly strong among females as well as those with low education levels.
CONCLUSIONS: This study reveals a longitudinal bidirectional relationship between knee osteoarthritis and frailty in middle-aged and older adults. In particular, the dominant role of frailty in the development of knee osteoarthritis was found, as well as the negative impact of knee osteoarthritis accumulation on frailty over time. This result suggests that targeting frailty early interventions in an ageing society may help to interrupt the vicious cycle of knee osteoarthritis and reduce the risk of disability. It provides a scientific basis for public health strategies.

Show summaryHide summary
BACKGROUND: Physical activity is protective against osteoarthritic development and is among the best approaches to manage frailty, which can be characterized as the presence of health deficits. It is unclear whether overall health of a person influences the relation between physical activity and knee-joint health.
OBJECTIVE: Test the hypothesis that physical activity is associated with knee osteoarthritis symptoms and investigate frailty as a moderator.
DESIGN: This cohort observational study included participants (n = 1351; 728 females) from the Osteoarthritis Initiative, aged 45–79 (60±9) years. Hip-worn accelerometers were used to quantify free-living stationary time, light (LPA) and moderate-to-vigorous-physical-activity (MVPA). The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) defined symptom progression. Baseline frailty was determined via a 31-item Frailty Index and participants grouped into Non-Frail (0–0.09), Very-Mild Frailty (0.1–0.19), and Mild Frailty+ (>0.2). Accelerometry and WOMAC were determined at 72-month follow-up.
RESULTS: MVPA (18±19mins/day) was negatively related to WOMAC outcomes (β<-0.0155, p < 0.0022), while LPA (274±79mins/day) was not (β<0.0005, p > 0.3061). Stationary time (606±88mins/day) was positively associated with WOMAC stiffness (β=0.0009, p = 0.0147). Frailty (0.134±0.077) did not moderate LPA and WOMAC relations (p > 0.308). A stronger negative relation between MVPA and WOMAC pain (β=-0.0092, p = 0.041) was observed in the Mild Frailty+ group compared to the Very-Mild Frailty and Non-Frail groups. A stronger positive relation between Stationary time and WOMAC stiffness (β=0.0013, p = 0.012) was observed in the Mild Frailty+ groups compared to the Very-Mild Frailty and Non-Frail groups.
CONCLUSION: Engaging in MVPA and limiting stationary time may be more beneficial on knee osteoarthritis pain and stiffness among frailer older adults.

Show summaryHide summary
BACKGROUND: There has been success in implementing frailty education for healthcare professionals, but there remains a need to improve the knowledge and skills of researchers and healthcare professionals to develop, implement and evaluate frailty-focused research.
OBJECTIVES: This paper describes how the Australian Frailty Network developed and evaluated a virtual community of practice (VCOP), a proven model for fostering knowledge mobilisation, to support researchers and healthcare professionals in advancing frailty research and practice in Australia.
DESIGN: Mixed methods.
SETTING: Australian research and healthcare workplaces.
PARTICIPANTS: Researchers and healthcare professionals.
MEASUREMENTS: A survey of prospective members sought to define the VCOP’s purpose, membership and structure. An evaluation was undertaken 18 months post-commencement, guided by the RE-AIM framework to assess reach, effectiveness, adoption, implementation and maintenance.
RESULTS: Fifty-five prospective members completed the initial survey. There was wide agreement from respondents to be inclusive in defining membership. The preferred purposes of the group included networking, opportunities to gain feedback, review frailty research, and knowledge and skill acquisition. In response, Frailty Nexus was launched, with three core components (‘Learning Link-Up’, online learning events; ‘Nexus News’, newsletter sharing learning and research opportunities; ‘Nexus Nook’, a library of shared resources). Membership totalled 618 from 81 organisations. Ninety-six percent of surveyed members expressed satisfaction with Frailty Nexus.
CONCLUSIONS: Frailty Nexus is contributing to capacity building in multidisciplinary and translational frailty research. This VCOP could serve as a model that can be adapted by others to improve research outcomes and policy implementation.

THE VITALITY DOMAIN OF INTRINSIC CAPACITY: A SCOPING REVIEW OF CONCEPTUAL FRAMEWORKS AND MEASUREMENTS
J. Chew, J. Lee, H.H.C. Hernandez, Y.L. Munro, C.L. Lim, W.S. Lim
J Frailty Aging 2025;14(4)
Show summaryHide summaryBACKGROUND: Intrinsic capacity (IC) is a composite indicator of physical and mental capacities that are critical for healthy aging. IC comprises five domains, with “vitality” gaining most attention due to its potential impact on functional and physiological reserves with increasing age. The World Health Organization 2022 framework redefined vitality as an underlying physiological determinant of IC. However, the concept and measurement of vitality and its empirical validation are not well defined.
OBJECTIVES: This scoping review aims to: (1) map the conceptual frameworks underpinning vitality within the IC domain and (2) identify existing measures used to assess vitality.
METHODS: A systematic search of MEDLINE, PubMed, Embase, Web of Science, and WHO databases (2003–2023) using Arksey and O’Malley’s framework and PRISMA-ScR guidelines. Studies involving adults ≥50 years old that addressed vitality in IC were included. We extracted data on conceptual frameworks, measurement tools, and construct validity.
RESULTS: Eighty-one studies met the inclusion criteria. Initial frameworks of vitality focused on nutritional indicators, while recent concepts include neuromuscular function, metabolism, and immune-stress responses. However, operationalization of these concepts remains inconsistent, with most studies relying on anthropometry, appetite, weight loss, and handgrip strength, while immune and stress response-related biomarkers were rarely assessed. Only 10.5 % of studies evaluated construct validity of vitality, and limited studies validated the potential roles of vitality underpinning the other expressed capacities.
CONCLUSIONS: Currently, vitality within IC varies in definitions and measurement approaches, with a predominant focus on nutrition and muscle strength. Empirical validation of vitality’s role as a foundational IC domain remains limited. Expanding the scope of vitality to include metabolic and immune markers, and deeper examination of the interactions between vitality with other IC domains may enhance understanding and improve assessment frameworks for healthy aging.

Show summaryHide summaryBACKGROUND: Falls are associated with an increased risk of frailty in middle-aged and older adults; however, the mediating role between falls and frailty remains underexplored, particularly among ethnic minority groups with distinct sociocultural and environmental exposures. Ethnic minority populations exhibit significant disparities in the prevalence of falls, frailty, and chronic pain compared to the majority. The primary objective of this study is to examine the relationship between falls and frailty in middle-aged and elderly individuals residing in Yunnan Province, China, with a specific emphasis on exploring the potential mediating effect of chronic pain across different ethnic groups.
METHODS: Employing a cross-sectional design, data were collected from July to December 2022 from adults aged ≥45 years in five ethnically diverse counties of Yunnan Province, China. Structured face-to-face interviews and stratified multistage cluster sampling were used for data collection. Baron and Kenny’s causal steps method was used to explore the mediating effect of chronic pain on the relationship between falls and frailty. Spearman correlation analysis, multiple linear regression models, and bootstrap method were used for data analysis.
RESULTS: A total of 2710 respondents participated in this study. The age distribution was as follows: 1161 (42.84 %) aged 45–59 years, 863 (31.85 %) aged 60–69 years, and 686 (25.31 %) aged 70 years or older. The sample comprised 1218 males (44.94 %) and 1492 females (55.06 %). The prevalence of falls among middle-aged and older individuals was 12.77 %, while the prevalence of frailty in the same population was observed to be 21.62 %. Spearman correlation analysis revealed significant positive association between chronic pain and both falls (r = 0.135, P < 0.05) as well as frailty (r = 0.383, P < 0.05). Frailty also exhibited a significant positive correlation with falls (r = 0.162, P < 0.05). After adjusting for all covariates, the total effect of falls on frailty was estimated to be 1.065 (95 % bootstrap CI: 0.804∼1.326), with a direct effect estimate of 0.797 (95 % bootstrap CI: 0.511∼1.083). The indirect effect of chronic pain on this association was found to be approximately one-quarter at 0.268 (95 % bootstrap CI: 0.170∼0.366). The subgroup analysis discovered differences in the mediating effects across different ethnic groups; specifically, the proportions mediated by chronic pain were found to be 28.2 %, 18.4 %, and 21.5 % for Han majority group, Zhiguo ethnic minorities, and other ethnic minority groups, respectively.
CONCLUSION: This study provides valuable insights into the intricate association between frailty, falls, and chronic pain among middle-aged and older adults from diverse ethnic backgrounds in a western province of China. Effective management strategies targeting chronic pain and falls prevention could serve as crucial interventions to address frailty.

Show summaryHide summaryBACKGROUND AND OBJECTIVES: The present study examined the associations between sarcopenia, operationalized through muscle strength or muscle power, and health parameters in Italian community-dwelling older adults. DESIGN: Cross-sectional study. SETTING: Unconventional settings across Italy. PARTICIPANTS: Italian older adults (65+ years) who provided a written informed consent. MEASUREMENTS: Physical function was evaluated according to isometric handgrip strength (IHG) and 5-time sit-to-stand (5STS) performances. Muscle power parameters were estimated based on 5STS values. Sarcopenia was operationalized according to the presence of low physical function (i.e., IHG or 5STS), or low muscle power, plus low appendicular skeletal muscle mass. Health parameters included the capacity to perform the 400 m test, adherence to the Mediterranean (MED) diet, practice of physical activity (PA), blood pressure (BP) values, blood concentration of total cholesterol and glucose, verbal fluency, sleep quality, and self-reported health status. RESULTS: Results indicated that sarcopenic indexes had a poor-to-moderate level of agreement. Moreover, results indicated that operationalizing sarcopenia using muscle power measures provided exclusive or stronger associations with health parameters. Specifically, older adults classified as sarcopenic based on muscle power values were less likely to complete the 400-meter walk test, more likely to engage in PA, reported poorer self-rated health, and showed lower adherence to the MED diet. CONCLUSIONS: Findings of the present study indicated that sarcopenia indexes based on muscle strength or muscle power capture different aspects of older adults’ health. Specifically, operationalizing sarcopenia using muscle power measures provided exclusive or stronger associations with health parameters.

Show summaryHide summaryBACKGROUND: Intrinsic capacity (IC) is a recent key concept proposed by the World Health Organization (WHO) based on aspects of functional ability (both physical and mental) rather than the presence or absence of diseases, with a potential to predict several health outcomes.
OBJECTIVE: To explore associations between IC and cognitive function (prospectively), and between IC and plasma p-tau181 (cross-sectionally and prospectively) among community-dwelling older adults.
METHODS: Observational study with 491 subjects ≥70 years (67.4 % female, mean 75.3 years, SD=4.4), participants from the Multidomain Alzheimer Preventive Trial (MAPT). IC domains (locomotion, cognition, psychological, vitality) were combined into a 0–100 score. Alternative classification was based on the number of domains’ abnormalities. Plasma p-tau181 was measured at baseline and 36 months of follow-up. A composite cognitive score (CCS) based on four tests was determined at baseline, 6, 12, 24, 36, 48 and 60 months.
RESULTS: Inverse cross-sectional associations were observed between baseline IC score and p-tau181 (unadjusted model: β=-0.08, 95 %CI -0.13 to -0.03; p = 0.0025). A significant mean difference in p-tau181 3-year changes was observed between participants with low and normal IC (based on IC score) (adjusted model: 1.71, 95 %CI 0.01 to 3.40; p = 0.0483). Prospective 5-year associations between IC and CCS were only observed in unadjusted analysis according to the alternative IC classification (-0.21, 95 %CI -0.38 to -0.04; p = 0.0156).
CONCLUSION: IC was associated with plasma p-tau181 and cognitive function, but findings varied according to the method of IC classification. Further research may help settle the role of IC as a predictor of neurodegenerative diseases such as AD. In this regard, multidomain interventions have potential to protect IC over the aging process and prevent cognitive impairment, and should also be encouraged.

J Frailty Aging 2025;14(4)
Show summaryHide summaryFrailty is a clinical syndrome characterized by diminished physiological reserves and increased vulnerability to stressors. While frailty has been largely studied in Alzheimer’s disease, few study focused on Lewy body dementia (LBD). Beyond frailty, the World Health Organization recently highlights the concept of intrinsic capacity (IC), offering a promising framework for the early identification and intervention to mitigate the risk of frailty and disability in older adults. IC refers to an individual's physical and mental abilities (including five dimensions: sensory, psychology, locomotion, vitality and cognition), which support the maintenance of functional capacity and promote healthy aging. In this review, we aimed to describe the prevalence of IC decline in LBD and its potential consequences. While few studies focused specifically on this question, we found evidence in the literature of a higher prevalence of IC decline in LBD, compared to cognitively unimpaired older adults and to Alzheimer’s disease patients. If future studies are needed to confirm these results, we assume that IC assessment and monitoring in LBD may be a further step towards a better integrated and personalized care for patients. This may open the avenue to develop specific tailored interventions, to decrease disability and increase quality of life and “healthy ageing” of patients despite the presence of LBD.

Show summaryHide summaryBACKGROUND: There is urgency to manage frailty due to its increasing prevalence. The Geriatric Service Hub (GSH) is a novel programme in Singapore, which aims to manage frailty amongst community-dwelling older adults.
OBJECTIVES: We aimed to (1) assess the effectiveness of the GSH through patient-outcomes including patient activation, functional status, and quality-of-life (QoL), and (2) assess impact on patient-outcomes through different levels of frailty using the Clinical Frailty Scale (CFS) scores.
DESIGN: Single-arm pre-post design.
SETTING: Community-based health and social care provider.
PARTICIPANTS: 218 GSH patients, aged≥65, with CFS4 to CFS7.
INTERVENTION: Patients received comprehensive geriatric assessments in community-based settings and had individualised care plans formed by a multi-disciplinary care team. Patients were then referred to health and social services located in the community based on identified needs.
MEASUREMENTS: Functional status (Barthel Index), Patient activation (Patient Activation Measure), health-related QoL (EuroQoL 5-dimension 5-level tool) and the emotional-related QoL (Control, Autonomy, Self-realisation, and Pleasure tool). Measurements administered at baseline, 3- and 6-months post-enrolment. Analysis included unadjusted t-tests and multi-level mixed-effects linear regression.
RESULTS: We studied 191 (87.6 %) participants who completed all 3-timepoints. Compared to baseline, functional status was maintained at 3-months (Mdiff=-0.2, 95 % CI [-1.8;1.3]) and 6-months (Mdiff=-0.5, 95 % CI[-2.2;1.2]). Patient activation increased slightly at 3-months (Mdiff=3.0, 95 % CI [0.1;5.9]) but not at 6-months (Mdiff=1.5, 95 % CI [-1.2;4.1]). There were significant increases for health-related QoL a t 3-months (Mdiff=0.068, 95 %CI [0.041;0.095]) and 6-months (Mdiff=0.045, 95 % CI [0.016;0.074]), and for emotional-related QoL at 3-months (Mdiff=2.3, 95 % CI [1.2;3.3]) and 6-months (Mdiff=1.5, 95 % CI [0.4;2.7]). For sub-group analyses, there were significant increases for patient activation and both QoL measurements for patients categorised as CFS4 and CFS5, and no significant changes for patient-outcomes for CFS6–7.
CONCLUSIONS: Overall, results suggest maintenance in patient activation and functional status, with improvements in QoL. Sub-group analyses suggest that GSH is beneficial for patients categorised as CFS4 and CFS5, but the programme played a largely maintenance role for patients with CFS6–7.

Show summaryHide summaryBACKGROUND: Longitudinal trajectories of healthcare utilization, medication prescription, and clinical outcomes among older adults with disabilities receiving home healthcare (HHC) holds significance but remains elusive.
METHODS: People aged≥65 years who newly received Taiwan’s National Health Insurance funded HHC program from January 2005 to December 2013 were identified. Healthcare utilization, life-sustaining treatment, medication prescriptions (polypharmacy, psychotropics, anticholinergic burden and antibiotics), health status (Charlson’s comorbidity index, CCI), and mortality were assessed over a 10-year period spanning 5 years before and after initiating HHC.
RESULTS: Overall, 187,547 patients (80.6 ± 7.7 years, 51.2 % females, CCI 3+: 51.2 %) with a high prevalence of dementia (34.0 %), stroke (38.7 %), and pneumonia (49.5 %), and usage of life-sustaining treatment (urinary catheters: 82.8 % and nasogastric feeding: 78.7 %) were obtained. A sudden peak of admission rate at 1 year (91.7 %) before HHC, followed by the 70 % and 60 % admission rate in the first and second year after receiving HHC were found. Quarterly changes of using life-sustaining treatment showed significant increases from as early as 1 year prior to HHC. Gradual increases of polypharmacy, use of psychotropics, and antibiotic (4.5-fold and 3-fold) after HHC further demonstrated the complex needs (both p < 0.01). The 5-year cumulative mortality rate was 81 % (40 % in the first year with an annual rate of 25 %).
INTERPRETATION: HHC recipients embody a confluence of complex care needs and high mortality risk, whereby various interventions aim to alleviate symptoms and sustain life. Engaging in proactive advanced care planning and end-of-life care should be prioritized when home healthcare is being contemplated.

This study investigated the association between a comprehensive lifestyle score, comprising eight modifiable factors (diet, physical activity, smoking, sleep, body mass index [BMI], non-HDL cholesterol, blood glucose, and blood pressure), and frailty risk in older adults, identifying key components for targeted interventions.
METHODS: Using data from the National Health and Nutrition Examination Survey (NHANES, 2005–2018), we analyzed 10,065 adults aged ≥60 years (mean age: 69.61, 54.97 % female). Each lifestyle factor was scored from 0 to 100, and frailty was defined using a 49-item index (>0.21). Weighted logistic regression assessed individual associations, restricted cubic spline (RCS) analysis explored dose-response relationships, and quantile g-computation evaluated joint effects.
RESULTS: Higher scores for dietary score (OR=0.69, 95 % CI: 0.52–0.90, score 100 vs. 0), non-smoking (OR=0.62, 95 % CI: 0.51–0.75), sleep (OR=0.29, 95 % CI: 0.17–0.49), blood glucose (OR=0.27, 95 % CI: 0.17–0.44), and blood pressure (OR=0.43, 95 % CI: 0.30–0.61, score 25 vs. 0) were associated with lower frailty risk (all P < .05). Diet and non-HDL cholesterol showed no linear association; smoking, BMI, blood glucose, and blood pressure exhibited non-linear patterns (P<.05). A simultaneous one-level increase in all lifestyle factors reduced frailty risk by 94 % (95 % CI: 92–95 %), with physical activity, blood glucose, and sleep as primary contributors.
CONCLUSION: These findings highlighted the association between specific lifestyle factors and reduced frailty risk, underscoring the need for prospective studies to prioritize interventions for frailty prevention.

Show summaryHide summaryBACKGROUND: Walking is a fundamental daily activity representing health status and physical condition. The number of steps taken in a given time period is widely used in research areas such as aging, geriatrics, gerontology, public health, and preventive medicine. However, the underlying mechanisms of step counts are not well understood.
OBJECTIVES: To investigate daily step counts associated with temperature, transportation, and marital status.
DESIGN: Time series analysis of daily steps using built-in healthcare applications on smartphones.
SETTING: Government-designated, well-developed urban cities in Japan: Fukuoka, Kawasaki, Kobe, Kyoto, and Saitama.
PARTICIPANTS: Respondents totaled 622 40- to 79-year-olds, comprising 370 males and 252 females.
MEASUREMENTS: The mean period of our retrospective data was 2,344 days.
RESULTS: Seasonal-trend decomposition using loess was applied to time series steps. With the high coefficient of determination R2: 0.798, an absolute value function was fitted between temperature and the mean daily steps of the seasonal component. Furthermore, ordinary train usage in Saitama, Kawasaki, and Fukuoka was significantly greater than that in Kobe and Kyoto by 14.1 points (p=0.001). Moreover, married and divorced or bereaved males’ mean daily step counts were significantly larger than those of females’ by 1,832 (p=0.001) and 2,480 (p=0.001), respectively. By contrast, the difference in the mean daily step counts for unmarried males and females was only 100.
CONCLUSIONS: This study presents significant associations between mean daily steps and the factors of temperature, transportation, and marital status. These associations can alleviate biases in step research by area and season to facilitate better step count comparisons in many research fields.

Show summaryHide summaryOBJECTIVE: To compare the association of glaucoma and glaucoma suspect diagnoses with frailty, quantified via an electronic frailty index (eFI), and to evaluate whether a glaucoma diagnosis moderates the association between frailty and the cumulative risk of acute healthcare encounters for incident falls or fractures.
DESIGN: Retrospective study of electronic health record (EHR) data.
SUBJECTS, PARTICIPANTS, AND/OR CONTROLS: Adults ≥65 years old with an ICD-10 diagnosis code for glaucoma or glaucoma suspect who had a calculable eFI score as of 10/1/2017.
METHODS: Ordinal logistic regression was used to examine the cross-sectional association between glaucoma (predictor) and frailty status (outcome) based on the eFI. The relationship of glaucoma and frailty with the cumulative incidence of hospital or emergency room visits for injurious falls or fractures over time was modeled using cause-specific recurrent event survival models that account for censoring and the competing risk of death.
MAIN OUTCOME MEASURES: Frailty status based on the eFI and cumulative incidence of falls or fractures. RESULTS: Glaucoma patients were significantly more likely to be frail compared to glaucoma suspects (adjusted odds ratio=1.36, 95 % CI(1.16, 1.60)). Both pre-frailty and frailty were associated with an increased risk of incident falls/fractures in older adults: prefrail (hazard ratio=2.07, 95 % CI (1.40, 3.06)), frail (hazard ratio=3.35, 95 % CI (2.24, 5.03)), but there was no interaction of frailty with glaucoma status on falls/fractures risk. Also, the risk of incident falls/fractures did not significantly differ between glaucoma versus glaucoma suspects.
CONCLUSIONS: Glaucoma patients were more likely to be frail or pre-frail based on an EHR-derived index than glaucoma suspects. Both pre-frailty and frailty were associated with increased cumulative risk of injurious falls or fractures but there was no interaction of frailty with glaucoma. Frailty based on the eFI was better at discriminating who is at risk of acute healthcare utilization for falls/fractures than a glaucoma diagnosis.

Show summaryHide summaryBACKGROUND: Frailty increases vulnerability for adverse outcomes in older adults. Characterizing the prevalence and distribution of frailty can help guide healthcare service decision-making and policy.
OBJECTIVES: This study evaluated the association between frailty and healthcare utilization and interactions by demographic characteristics.
DESIGN: Using electronic health records (2018–2022), we conducted a retrospective cohort study with 355,266 patients ≥65 years of age who had ≥2 ambulatory office visits in separate years in the 4-year baseline period (2018–2021). The Gilbert Frailty Index (GFI) was calculated (low vs. intermediate vs. high) using ICD-10 codes. One-year utilization outcomes in 2022 included high outpatient clinic utilizations (OCU), inpatient (IP), emergency department (ED), and nursing home (NH) admissions. Fully adjusted log-binomial regression models were calculated overall and by race (White vs. Black), age groups, and gender.
RESULTS: The sample was 74.5(±7.5) years of age, 57.7 % female, 89.2 % White, and 13.5 % categorized as GFI high. After adjustment for covariates, GFI high had the highest risk for all outcomes (RR=3.31 for IP; 2.77 for ED; 4.26 for NH; 1.60 for high OCU). We observed significant interactions by race, gender, and age for some outcomes. Effects of GFI high vs. low were larger for White (IP, ED, & high OCU), female patients (ED & high OCU), and younger patients (IP). Conversely, the effects of GFI high vs. low were strongest in older patients for ED, IP and high OCU.
CONCLUSIONS: Monitoring frailty and paying attention to patient’s demographic characteristics is needed to best estimate associations between frailty and healthcare utilization.
