Application, knowledge and training needs regarding comprehensive geriatric assessment among geriatric practitioners in healthcare institutions: a cross-sectional study.

BACKGROUND: This study aimed to investigate the actual application, knowledge, and training needs of comprehensive geriatric assessment (CGA) among geriatric practitioners in China. METHODS: A total of 225 geriatric practitioners attending the geriatric medicine or geriatric nursing training were recruited for this cross-sectional study. The questionnaire included demographics, healthcare institution characteristics, the actual application, knowledge, training needs, and barriers to CGA and geriatric syndromes (GS). RESULTS: Physicians and nurses were 57.3% and 42.7%, respectively. 71.1% were female, with a median age was 35 years. Almost two-thirds (140/225) of geriatric practitioners reported exposure to CGA in their clinical practice. The top five CGA evaluation items currently used were malnutrition risk (49.8%), fall risk (49.8%), activity of daily living (48.0%), pain (44.4%), and cognitive function (42.7%). Median knowledge scores for the management procedures of GS ranged from 2 to 6. Physicians identified medical insurance payment issues (29.5%) and a lack of systematic specialist knowledge and technology (21.7%) as the two biggest barriers to practicing geriatrics. Nurses cited a lack of systematic specialist knowledge and technology (52.1%) as the primary barrier. In addition, physicians and nurses exhibited significant differences in their knowledge of CGA-specific evaluation items and management procedures for GS (all P < 0.05). However, there were no significant differences in their training needs, except for polypharmacy. CONCLUSIONS: The rate of CGA application at the individual level, as well as the overall knowledge among geriatric practitioners, was not adequate. Geriatric education and continuous training should be tailored to address the specific roles of physicians and nurses, as well as the practical knowledge reserves, barriers, and training needs they face.

Associations of intrinsic capacity, fall risk and frailty in old inpatients.

Introduction: This study explored the associations of intrinsic capacity (IC), fall risk, and frailty in geriatric inpatients. Methods: A total of 703 hospitalized patients aged 75 years or older were recruited for this retrospective observational study from Zhejiang Hospital using a comprehensive geriatric assessment. The IC composite score was constructed from the scores of the Chinese version of the Mini-Mental State Examination, Short Physical Performance Battery, Short Form Mini Nutritional Assessment, 15-item Geriatric Depression Scale, and self-reported hearing and vision impairment. Adverse outcomes were recorded as the fall risk and frailty using the Morse Fall Scale and the Clinical Frailty Scale. Spearman's correlation coefficient analyses and multivariate logistic regression models were used to explore the associations between IC, high fall risk, and frailty. Results: Declined IC composite scores were associated with increased risks of falls [odds ratio (OR) = 0.64, 95% confidence interval (CI): 0.57-0.72] and frailty (OR = 0.45, 95%CI: 0.37-0.54) among older hospitalized patients after adjusting for the related potential confounders. In addition, decreased cognitive, vitality, locomotion, and psychological scores were associated with increased adverse health conditions, with ORs ranging from 0.26 to 0.70. Vision impairment was observed to increase the risk of frailty (OR = 0.42, 95%CI: 0.23-0.76) after adjusting for the related potential confounders. Discussion: This study indicated that declined IC was associated with fall risk and frailty in older inpatients. Further prospective studies are needed to explore the longitudinal associations between baseline IC and subsequent risk of falls and frailty.

Coexisting Frailty and Cognitive Impairment as a Predictor of Adverse Outcomes in Older Inpatients After Discharge: Results from a One-Year Follow-Up Study.

Purpose: This study aimed to investigate the combined effects of frailty and cognitive impairment on adverse outcomes, including new falls and new activities of daily living (ADL) dependency over a 1-year follow-up. Patients and Methods: A total of 311 older hospitalized patients participated in this retrospective observational study and completed a 1-year follow-up. Frailty was assessed by the Clinical Frailty Scale (CFS). Cognitive function was evaluated by the Mini-Mental State Examination (MMSE). All participants were classified into four groups: 1) the healthy group (n=180); 2) the cognitive impairment group only (n=38); 3) the frailty group only (n=44); and 4) coexisting frailty and cognitive impairment group (n=49). The follow-up data of adverse outcomes include the incidences of new falls and new ADL dependence. Binary logistic regression analysis was used to explore the associations of frailty and/or cognitive impairment with adverse outcomes. Results: The prevalence rates of frailty, cognitive impairment, and co-occurring frailty with cognitive impairment were 29.9%, 28%, and 15.8%, respectively. Among these four groups, there was a statistical difference in the incidence of new ADL dependence during the follow-up period (9.5% vs 11.4% vs 35.9% vs 61.9%, P < 0.001). After adjusting the confounding variables, older hospitalized patients with frailty and cognitive impairment had a higher risk of new ADL dependence when compared with the healthy group (OR: 4.786, 95% CI: 1.492-15.355), but frailty only or cognitive impairment only was not associated with new ADL dependency. Conclusion: Elderly inpatients with comorbid frailty and cognitive impairment on admission were significantly associated with an increased risk of new ADL dependency 1 year after discharge. Therefore, it is necessary for the early identification of frailty and cognitive impairment, and effective interventions should be implemented.

Associations of poor sleep quality, chronic pain and depressive symptoms with frailty in older patients: is there a sex difference?

BACKGROUND: Sleep disturbance, chronic pain and depressive symptoms later in life are modifiable risk factors and may contribute to frailty. However, much less is known about sex differences in the association between these concurrent symptoms and frailty in older patients. Therefore, we conducted this study to explore the associations of poor sleep quality, chronic pain, and depressive symptoms with frailty in older patients, and the sex-specific associations. METHODS: In an observational population-based study, 540 older hospitalized patients from Zhejiang Hospital in China were enrolled. We collected data on poor sleep quality, pain, depressive symptoms and frailty using the Pittsburgh Sleep Quality Index, the Numerical Rating Scale, the 15-item Geriatric Depression Scale, and the Clinical Frailty Scale. Multivariate logistic regression models were used to explore the total sample and sex-specific associations among symptom burdens, symptom combination patterns and symptom counts, and frailty. RESULTS: After adjusting for the potential covariates, concurrent poor sleep quality and depressive symptoms (OR = 4.02, 95% CI 1.57-10.26), concurrent poor sleep quality and chronic pain (OR = 2.05, 95% CI 1.04-4.05), and having three symptoms (OR = 3.52, 95% CI 1.19-10.44) were associated with a higher likelihood of frailty in older inpatients. In addition, older patients with 2 or 3 symptoms (2 and 3 vs. 0 symptoms) had a higher risk of frailty, and the odds ratios were 2.40 and 3.51, respectively. Interaction analysis and sex-stratified associations exhibited conflicting results. The nonsignificant effect of the interaction of sex and symptoms on frailty, but not the sex-stratified associations, showed that individual symptoms, symptom combination patterns, and symptom counts were associated with elevated risks of frailty in older male patients, but not in older female patients. CONCLUSIONS: Increased symptom burdens were associated with a higher risk of frailty in older inpatients, especially in those with poor sleep quality concurrent with at least one of the other two symptoms. Thus, a multidisciplinary program addressing these common symptoms is required to reduce adverse outcomes.

The Impact of Intrinsic Capacity on Adverse Outcomes in Older Hospitalized Patients: A One-Year Follow-Up Study.

BACKGROUND: Intrinsic capacity (IC) is a novel view focusing on healthy aging. The effect of IC on adverse outcomes in older hospitalized Chinese adults is rarely studied. OBJECTIVES: This study focused on investigating the impact of IC domains on the adverse health outcomes including new activities of daily living (ADL) dependency, new instrumental activities of daily living (IADL) dependency, and mortality over a 1-year follow-up. METHODS: In a retrospective observational population-based study, a total of 329 older hospitalized patients from Zhejiang Hospital in China were enrolled and completed 1-year follow-up. The 5 domains of IC including cognition, locomotion, sensory, vitality, and psychological capacity were assessed at admission. The IC composite score was calculated based on these domains, and the higher IC composite score indicated the greater amount of functional capacities reserved. Multivariate logistic regression models were used to explore the association between IC at baseline and 1-year adverse outcomes. RESULTS: During the 1-year follow-up, 69 patients (22.5%) experienced new ADL dependency, 103 patients (33.6%) suffered from new IADL dependency, and 22 patients (6.7%) died. After adjusting for age, sex, education level, comorbidities, and polypharmacy, low Mini-Mental State Examination (MMSE) scores at admission predicted 1-year new ADL dependency (odds ratio [OR] = 2.31, 95% confidence interval [CI]: 1.12-4.78) and new IADL dependency (OR = 2.15, 95% CI: 1.14-4.04) among older hospitalized patients, but no significance was obtained between IC domains and mortality. Higher IC composite score at admission was associated with decreased risks of 1-year new ADL dependency (OR = 0.53, 95% CI: 0.40-0.70) and new IADL dependency (OR = 0.76, 95% CI: 0.61-0.95), and 1-year mortality (OR = 0.48, 95% CI: 0.31-0.74) after adjustment for the possible confounders. CONCLUSIONS: Loss of ICs at admission predicted adverse health outcomes including new ADL and IADL dependency and mortality 1 year after discharge among older hospitalized patients.

Association Between Body Composition and Frailty in Elder Inpatients.

PURPOSE: The study aimed to investigate the association between body composition and frailty in elder inpatients. PATIENTS AND METHODS: This is a cross-sectional study including 656 elder inpatients (275 females and 381 males) aged ≥65 years, from department of geriatrics of Zhejiang Hospital between January 2018 and March 2019. Sociodemographic, health-related data and anthropometric measurements were evaluated. Body composition was assessed by bioimpedance analysis (BIA), mainly including skeletal muscle mass, body fat mass, total body water, fat-free mass,percent body fat, basal metabolic rate. Frailty was assessed by Clinical Frailty Scale (CFS). Univariate logistic regression was used to analyze the association between body composition and frailty. RESULTS: Frailty was present in 43.9% of the participants. Frail inpatients showed higher waist circumference, body fat mass and percent body fat, non-frail inpatients showed greater upper arm circumference, calf circumference, skeletal muscle mass, total body water, fat-free mass and basal metabolic rate. Subjects with underweight (body mass index (BMI)<18.5 kg/m2; odds ratio (OR), 95% confidence interval (CI)=4.146 (1.286-13.368) P=0.017) and those with high waist circumference (OR 95% CI=1.428 (0.584-3.491) P<0.001), body fat mass (OR, 95% CI=1.143 (0.892-1.315) P<0.001) presented a higher risk of frailty compared to normal subjects. Skeletal muscle mass (OR; 95% CI=0.159 (0.064-0.396) P<0.001) was a protective factor for frailty. CONCLUSION: Frailty in elder Chinese inpatients was characterized by a body composition phenotype with underweight, high waist circumference, low skeletal muscle mass and high body fat mass. Underweight, abdominal obesity and sarcopenic obesity may, therefore, be targets for intervention of frailty.

Association between motoric cognitive risk syndrome and frailty among older Chinese adults.

BACKGROUND: Motoric cognitive risk syndrome (MCR) is a newly proposed predementia syndrome incorporating subjective cognitive complaints and slow gait. Previous studies have reported that subjective cognitive complaints and slow gait are associated with frailty in cognitively unimpaired older adults, but little is known about the link between MCR and frailty in older adults. Therefore, the aim of the study was to explore the associations of MCR and its components with frailty in older Chinese adults. METHODS: In an observational cross-sectional study, a total of 429 older adults aged 60 years and older were admitted to the geriatric department. According to MCR criteria, all participants were classified into 4 groups: 1) the MCR group; 2) the subjective cognitive complaints only group; 3) the slow gait only group; and 4) the healthy control group. Physical frailty was assessed by the Clinical Frailty Scale (CFS). Multivariate logistic regression analysis was used to examine the association between MCR and frailty in older adults. RESULTS: The prevalence rates of subjective cognitive complaints, slow gait and MCR were 15.9, 10.0 and 4.0%, respectively. After adjusting for confounding variables, the logistic regression analysis showed that slow gait (odds ratio [OR]: 3.40, 95% confidence interval [CI]: 1.40-8.23, P = 0.007) and MCR (OR: 5.53, 95% CI: 1.46-20.89, P = 0.012) were independently associated with frailty, but subjective cognitive complaints were not. CONCLUSIONS: MCR and slow gait were significantly associated with frailty in older Chinese adults. Further studies should prospectively determine the causal relationship between MCR and frailty.

Relationship between nutritional status and frailty in hospitalized older patients.

OBJECTIVE: The definition of frailty still lacks quantitative biomarkers. This study aimed to investigate the relationship between nutrition-related biomarkers and frailty in hospitalized older patients. MATERIALS AND METHODS: This is a cross-sectional study including 380 hospitalized older patients. The patients were categorized as nonfrail (n=140), prefrail (n=81), and frail (n=159) by the criteria of frailty phenotype. The nutritional status was assessed using the mini nutritional assessment-short form (MNA-SF), levels of serum transferrin (TNF), prealbumin (PA), total protein (TP), albumin (ALB), retinol-binding protein (RBP), and hemoglobin (Hb). RESULTS: The grip strength, levels of serum TFN, TP, ALB, Hb, and MNA-SF scores all decreased significantly in the order of nonfrail, prefrail, and frail groups (P<0.01). Older ages, more fall incidents, and higher polypharmacy ratio were observed in the frail and prefrail groups than in the nonfrail group (P<0.05). Univariate logistic regression analysis showed that frailty was positively related to age, polypharmacy, fall history, nutritional status, levels of TFN, PA, TP, ALB, RBP, and Hb, but was negatively related to grip strength. Ordinal logistic regression analysis showed that older patients who were well nourished, with higher levels of TFN, TP, and ALB were less likely to develop into frailty. CONCLUSION: Hospitalized older patients with better nutritional status and higher levels of TFN, TP, and ALB were less likely to develop into frailty. These nutrition-related biomarkers may be used for the evaluation of nutritional status and frailty in older patients.

Effects of a nutrition plus exercise programme on physical function in sarcopenic obese elderly people: study protocol for a randomised controlled trial.

INTRODUCTION: With a rapidly ageing population, sarcopenic obesity, defined as decreased muscle mass and function combined with increased body fat, is a complex health problem. Although sarcopenic obesity contributes to a decline in physical function and exacerbates frailty in older adults, evidence from clinical trials about the effect of exercise and nutrition on this complex syndrome in Chinese older adults is lacking. METHODS AND ANALYSIS: We devised a study protocol for a single-blind randomised controlled trial. Sarcopenia is described as age-related decline in muscle mass plus low muscle strength and/or low physical performance. Obesity is defined as a percentage of body fat above the 60th centile. Ninety-two eligible participants will be randomly assigned to a control group, nutrition group, exercise group and nutrition plus exercise group to receive an 8-week intervention and 12-week follow-up. The primary outcomes will be the change in short physical performance battery scores, grip strength and 6 m usual gait speed. The secondary outcomes will include basic activities of daily living scores, instrumental activity daily living scores, body composition and body anthropometric indexes. For all main analyses, the principle of intention-to-treat will be used. ETHICS AND DISSEMINATION: This study was approved by the medical ethics committee of Zhejiang Hospital on 25 November 2015. The study will present data targeting the clinical effects of nutrition and exercise on physical function and body composition in a Chinese older population with sarcopenic obesity. The results will help to provide important clinical evidence of the role of complex non-pharmaceutical interventions for sarcopenic obese older people. The findings of this study will be submitted to peer-reviewed medical journals for publication and presented at relevant academic conferences.

Relationship of serum vitamin D level on geriatric syndromes and physical performance impairment in elderly hypertensive patients.

OBJECTIVE: To investigate the relationship among serum vitamin D levels, physical performance impairment, and geriatric syndromes in elders with hypertension. METHODS: According to the concentration of vitamin D levels, a total of 143 elderly patients with hypertension were classified into vitamin D deficient group (vitamin D ≤ 20 ng/mL, n = 94) and vitamin D appropriate group (vitamin D > 20 ng/mL, n = 49). Geriatric syndromes and physical performance were assessed by using comprehensive geriatric assessment (CGA). Correlation among vitamin D levels, geriatric syndromes and physical performance was analyzed. RESULTS: No statistical differences were found in various aspects of geriatric syndromes between the two groups (P > 0.05). While correlation analysis indicated that vitamin D levels had a positive association with ADL score (r = 0.235, P < 0.01) and a negative association with Morse fall scale score (r = -0.238, P < 0.01). Patients with deficient vitamin D level had longer time both in the Five Time Sit to Stand Test (5tSTS), (15.765 ± 5.593) and the four-meter walk test [7.440 (5.620, 9.200)], a weaker hand-grip in the grip strength test (28.049 ± 9.522), and a lower Tinetti performance-oriented mobility assessment (Tinetti POMA) [26 (22, 27)] and Balance subscale of the Tinetti performance-oriented mobility assessment (B-POMA) score [14 (12, 16)], compared with appropriate vitamin D level [(13.275 ± 3.692); 5.810 (4.728, 7.325)]; (31.989 ± 10.217); [26.5 (25, 28)]; [15 (14, 16), respectively, all P < 0.05]. Furthermore, results of logistic regression indicated that vitamin D was significantly associated with 5tSTS (OR = 1.2, 95% CI = 1.050-1.331, P < 0.01), Tinetti POMA (OR = 3.7, 95% CI:1.284-10.830, P < 0.05) and B-POMA (OR = 0.8, 95% CI:0.643-0.973, P < 0.05). CONCLUSIONS: In elderly hypertensive patients, serum vitamin D deficient level is associated with physical performance impairment. However, no statistical significance was found between vitamin D and geriatric syndromes. Further study is required to investigate possible mechanisms for the association between vitamin D and physical performance.
