Translation and validation of the Korean version of the clinical frailty scale in older patients

Effect of Exercise and Nutrition Intervention for Older Adults with Impaired Physical Function with Preserved Muscle Mass (Functional Sarcopenia): A Randomized Controlled Trial

Background

Functional sarcopenia is characterized by decreased physical performance and grip strength despite preserved muscle mass. The effectiveness of a program combining exercise and nutritional support-known interventions for individuals with low muscle mass-was evaluated for its impact on older adults with functional sarcopenia.

Methods

An unblinded, parallel-group randomized controlled trial was conducted in a public medical center in a rural Korean community. Eligible older adults with functional sarcopenia were randomized into either the intervention group, receiving a 12-week program of group exercises and nutritional support, or the control group, receiving education on lifestyle management. Outcomes measured included changes in gait speed, grip strength, physical performance, and quality of life indices.

Results

The study enrolled 42 participants, with 21 allocated to each group. Compared with the control group, the intervention group showed significant improvements in the primary outcome of gait speed (mean change (m/s) 0.24 vs 0.00, p<0.001) and secondary outcomes, such as Short Physical Performance Battery scores, grip strength, and quality of life. No significant adverse events were reported.

Conclusion

The 12-week exercise and nutritional intervention significantly enhanced physical performance, grip strength, and quality of life among community-dwelling older adults with functional sarcopenia. This suggests that strategies commonly recommended for sarcopenia, including exercise and nutritional support, are also beneficial for individuals with functional sarcopenia, indicating the potential for broader application of such interventions.

Validation of the Japanese version of the Clinical Frailty Scale

AIM

Among the many screening tools developed to detect frailty and disability in older adults, the Clinical Frailty Scale (CFS) is a valid, reliable, and easy-to-use tool and has been translated into several languages. The aim of this study was to demonstrate the validity of the Japanese version of the CFS (CFS-J).

METHODS

The necessary permissions were obtained from Rockwood and colleagues. The Japanese version was prepared by translation (English to Japanese) and verified by back translation (Japanese to English). Concurrent criterion validity was assessed by evaluating the extent to which CFS relates to the Frailty Index (FI), the Frailty Index based on a Comprehensive Geriatric Assessment (FI-CGA), and Performance Status (PS), using Kendall's tau.

RESULTS

In total, 223 patients admitted to the geriatric ward of an acute hospital between June 2021 and March 2023 were analyzed in the validation study. Mean age was 84.9 ± 5.9 years (range, 67-101 years), 128 (57.4%) were women, and the mean body mass index was 20.9 ± 4.0 kg/m2. In a correlation analysis, significantly positive associations were found between the CFS-J and the FI (r = 0.713, P < 0.001), the FI-CGA (r = 0.691, P < 0.001), and PS (r = 0.669, P < 0.001) for numerical variables. Significant positive associations were also found between the CFS-J and the FI (r = 0.567, P < 0.001) and the FI-CGA (r = 0.591, P < 0.001) for categorical valuables.

CONCLUSION

The CFS-J was found to be a valid instrument for identifying frailty in Japanese inpatients. Geriatr Gerontol Int 2025; ••: ••-••.

Cross-Cultural Adaptation of the Clinical Frailty Scale for Critically Ill Patients in Spain and Concurrent Validity With FRAIL-Es

AIMS

To adapt the Clinical Frailty Scale (CFS) into Spanish and assess its concordance with the Spanish version of the FRAIL scale (FRAIL-Es) in the context of intensive care.

DESIGN

Validation study of frailty assessment scales in critically ill patients.

METHODS

The study was conducted in two phases. The first phase consisted of translating, culturally adapting, and validating the CFS into Spanish. The second phase consisted of a metric descriptive study to assess the concurrent criterion validity of the adapted CFS with FRAIL-Es in a cohort of intensive care patients. Both scales were assessed upon admission to intensive care and at 3, 6, 9, and 12 months post-hospital discharge. Analysis was performed using T-Student/Mann-Whitney, chi-squared and Cohen's Kappa tests.

RESULTS

Successful adaptation of the CFS with minimal changes was achieved, demonstrating its applicability in the evaluated context. The pilot study indicated that CFS-Es is easy to assess, but some subjectivity in interpretation was noted. CFS-Es and FRAIL-Es were applied to 212 patients, revealing variations in frailty prevalence. The concordance and correlation between the CFS and FRAIL scales are robust. These differences suggest that the choice of scale may impact the identification of frail patients. These results emphasise the importance of considering specific characteristics of each scale when assessing frailty in critically ill patients, providing valuable information for clinical implementation and research in this field.

PATIENT OR PUBLIC CONTRIBUTION

Assessing frailty upon admission can be helpful in the care of frail patients, allowing the development of specific care plans based on pre-existing frailty.

Impact of Multidrug-Resistant Bacterial Colonization on Clinical Characteristics, Antibiotic Treatment, and Clinical Outcomes of Hospital-Acquired Pneumonia

PURPOSE

To determine effects of colonization with multidrug-resistant bacteria (MDRB) in general wards on characteristics, treatment, and prognosis of hospital-acquired pneumonia (HAP).

METHODS

This was a multicenter retrospective cohort study of patients with HAP admitted to 16 tertiary or university hospitals in Korea from July 2019 to December 2019. From the entire cohort, patients who developed pneumonia in general wards with known colonization status before the onset of pneumonia were included in this study. Patients were categorized into a colonization group and a non-colonization group according to MDRB colonization. Patients of the two groups were then compared.

RESULTS

Among a total of 400 patients, 63 were in the MDRB colonization group. HAP caused by MDR-Staphylococcus aureus or MDR-Pseudomonas aeruginosa was more common in the colonization group than in the non-colonization group (24.4% vs. 8.1%, P = 0.006 or 20.0% vs. 5.4%, P = 0.013, respectively). Colonization with certain bacteria was correlated with subsequent infection with the same bacteria. Carbapenem use (36.5% vs. 24.3%, P = 0.044) and appropriateness of initial antibiotics (50.8% vs. 12.8%) were higher in the colonization group than in the non-colonization group. Although in-hospital mortality was similar in the two groups (34.9% vs. 32.9%, P = 0.759), hospital length of stay was longer (38 days vs. 31 days, P = 0.009) and rate of discharge to home was lower (34.1% vs 59.7%, P = 0.002) in the colonization group.

CONCLUSIONS

Colonization with MDRB might influence characteristics and treatment of HAP. However, prognosis of HAP was not associated with MDRB colonization.

Widely Integrated Services in Home (WISH) for homebound older adults: a study protocol for a randomized encouragement trial

BACKGROUND

Home-based primary care (HBPC) is an emerging patient-centered, interprofessional healthcare service model that can address unmet medical needs and care burdens for homebound older adults. In December 2022, the Ministry of Health and Welfare in South Korea launched the Home-Based Medical Center Demonstration project to provide a new bundle payment for physician home visits. In this study, we seek to determine whether the recently introduced HBPC services in South Korea have been associated with a reduction in long-term care (LTC) facility admissions and acute hospitalizations among homebound older adults.

METHODS

The study is a community-based, multicenter, two-arm, randomized encouragement design trial with a 12-month follow-up period (n = 600). Eligible study participants are community-dwelling LTC recipients with multimorbidity and functional deterioration. Study participants are recruited from five HBPC centers located in urban areas (Northeast Seoul, West Seoul, Daejeon, Wonju, and Paju). The study participants are randomly assigned to either the HBPC group or the usual care group with a 1:1 allocation ratio. Those assigned to the HBPC group receive longitudinal home visits at least once a month by an interprofessional HBPC team according to the Widely Integrated Services in Home (WISH) intervention protocol. This protocol adheres to the Integrated Care for Older People principles, which call for a person-centered assessment and broader integration of health and LTC services at the micro-, meso- and macro-levels. Primary outcomes of the trial are 1) between-group community survival days and 2) between-group potentially avoidable hospitalizations. Results of the treatment are estimated by both modified intention-to-treat and complier average causal effect analytic methods.

DISCUSSION

This study aims to investigate the real-world effectiveness of HBPC on the reduction of LTC facility admissions and acute care hospitalizations in the community setting. The findings may inform healthcare policy decisions to expand HBPC services in South Korea and other countries.

Comparative Clinical Characteristics of Frail Older Adults in the Emergency Department: Long-Term Care Hospital versus Community Residence

BACKGROUND/OBJECTIVE

Older patients from long-term care hospitals (LTCHs) presenting to emergency departments (EDs) exhibit a higher prevalence of frailty than those from the community. However, no study has examined frailty in patients from LTCHs in the ED. This study compared frailty in older patients from LTCHs and the community.

METHODS

We retrospectively analyzed data from the EDs of three university hospitals between 1 August and 31 October 2023, involving 5908 patients (515 from LTCHs and 5393 from the community). The Korean version of the Clinical Frailty Scale (CFS-K) was used to assess individuals aged 65 and older. We compared clinical characteristics, frailty, length of stay (LOS), and diagnosis between patients from LTCHs (LTCH group) and the community (community group).

RESULTS

Among ED patients, 55.0% and 35.2% in the LTCH and the community groups, respectively, were frail (p < 0.001). Of these, 71.7% in the LTCH group were hospitalized compared with 53.1% in the community group (p = 0.001). The odds ratio for in-hospital mortality was 4.910 (95% CI 1.458-16.534, p = 0.010) for frail LTCH patients and 3.748 (95% CI 2.599-5.405, p < 0.001) for frail community patients, compared to non-frail patients.

CONCLUSIONS

Patients from LTCHs with frailty had higher hospital admission rates and increased in-hospital mortality compared to those in the community at the same frailty level. This study offers essential insights into the characteristics of older patients in LTCHs for healthcare administrators and medical staff worldwide.

Validation of the Korean Version of the Clinical Frailty Scale-Adjusted Korean Triage and Acuity Scale for Older Patients in the Emergency Department

Background and Objectives: The Clinical Frailty Scale (CFS), used to screen for prehospital frailty in patients aged >65 years, is simple, time-efficient, and has been validated in emergency departments (EDs). In this study, we analyzed whether the Korean Triage and Acuity Scale (KTAS) classification by level in older patients determined to have frailty based on the Korean version of the CFS increases the triage performance of the current KTAS. Materials and Methods: The primary outcome was 30-day in-hospital mortality, and secondary outcomes were hospital and intensive care unit (ICU) admissions. This study retrospectively analyzed prospectively collected data from three ED centers. Patients with a CFS score ranging from five (mildly frail) to nine (terminally ill) were categorized into the frailty group. We upgraded the KTAS classification of the frailty group by one level of urgency and defined this as the CFS-KTAS. Results: The cutoff values for predicting admission were three and two for the KTAS and CFS-KTAS, respectively. A significant difference was observed in the area under the receiver operating characteristic (AUROC) curve between the KTAS and CFS-KTAS. To predict ICU admission, the cutoff score was two for both scales. A significant difference was observed in the AUROC curve between the KTAS and CFS-KTAS. For predicting in-hospital mortality, the cutoff score was two for both scales. A significant difference was observed in the AUROC curve between the KTAS and CFS-KTAS. Conclusions: This study showed that the CFS-adjusted KTAS has a more useful prognostic value than the KTAS alone for predicting hospital outcomes in older patients.

Clinical Manifestations and Outcomes of Older Patients with COVID-19: A Comprehensive Review

The consequences of coronavirus disease 2019 (COVID-19) are particularly severe in older adults with a disproportionate number of severe and fatal outcomes. Therefore, this integrative review aimed to provide a comprehensive overview of the clinical characteristics, management approaches, and prognosis of older patients diagnosed with COVID-19. Common clinical presentations in older patients include fever, cough, and dyspnea. Additionally, preexisting comorbidities, especially diabetes and pulmonary and cardiovascular diseases, were frequently observed and associated with adverse outcomes. Management strategies varied, however, early diagnosis, vigilant monitoring, and multidisciplinary care were identified as key factors for enhancing patient outcomes. Nonetheless, the prognosis remains guarded for older patients, with increased rates of hospitalization, mechanical ventilation, and mortality. However, timely therapeutic interventions, especially antiviral and supportive treatments, have demonstrated some efficacy in mitigating the severe consequences in this age group. In conclusion, while older adults remain highly susceptible to severe outcomes from COVID-19, early intervention, rigorous monitoring, and comprehensive care can play a pivotal role in improving their clinical outcomes.

Global frailty screening tools: Review and application of frailty screening tools from 2001 to 2023

As the aging population increases globally, health-related issues caused by frailty are gradually coming to light and have become a global health priority. Frailty leads to a significantly increased risk of falls, incapacitation, and death. Early screening leads to better prevention and management of frailty, increasing the possibility of reversing it. Developing assessment tools by incorporating disease states of older adults using effective interventions has become the most effective approach for preventing and controlling frailty. The most direct and effective tool for evaluating debilitating conditions is a frailty screening tool, but because there is no globally recognized gold standard, every country has its own scale for national use. The diversity and usefulness of the frailty screening tool has become a hot topic worldwide. In this article, we reviewed the frailty screening tool published worldwide from January 2001 to June 2023. We focused on several commonly used frailty screening tools. A systematic search was conducted using PubMed database, and the commonly used frailty screening tools were found to be translated and validated in many countries. Disease-specific scales were also selected to fit the disease. Each of the current frailty screening tools are used in different clinical situations, and therefore, the clinical practice applications of these frailty screening tools are summarized graphically to provide the most intuitive screening and reference for clinical practitioners. The frailty screening tools were categorized as (ⅰ) Global Frailty Screening Tools in Common; (ⅱ) Frailty Screening Tools in various countries; (ⅲ) Frailty Screening Tools for various diseases. As science and technology continue to advance, electronic frailty assessment tools have been developed and utilized. In the context of Coronavirus disease 2019 (COVID-19), electronic frailty assessment tools played an important role. This review compares the currently used frailty screenings tools, with a view to enable quick selection of the appropriate scale. However, further improvement and justification of each tool is needed to guide clinical practitioners to make better decisions.

Preoperative frailty assessment with ultrasound in elderly patients scheduled for total knee arthroplasty

BACKGROUND

Frailty, a decline in physical and cognitive reserve capacity, renders patients susceptible to various stressors and has been linked to adverse outcomes and increased healthcare utilization. This study aimed to determine whether ultrasound measurements of the rectus abdominis (RA) and biceps brachii (BB) could predict frailty in patients scheduled for total knee arthroplasty.

METHODS

Frailty was assessed using the Clinical Frailty Scale in adults aged ≥60 years. Ultrasound measurements of the rectus abdominis, BB, and quadriceps femoris muscles, along with thigh circumference measurements, were obtained before surgery. The predictive ability of the unadjusted and BMI- and body surface area (BSA)-adjusted measurements were evaluated using receiver operating characteristic curve analysis and area under the curve (AUC) values. Postoperative outcomes, such as admission to the intensive care unit or skilled nursing facility, delirium, falls, re-hospitalization, and 30-day mortality were recorded.

RESULTS

We analyzed data from 148 patients. BB thickness provided a fair prediction of frailty. Average measurements of both BB adjusted for BMI (0.708, 95% CI 0.602-0.814; P<0.001), and BSA (0.708, 95% CI 0.598-0.817; P<0.001) had the highest AUC values. RA muscle measurements could not discriminate frailty. The BMI-adjusted measurements for: right quadriceps femoris thickness (AUC 0.614, 95% CI 0.503-0.725; P=0.044), left thigh circumference (AUC 0.648, 95% CI 0.528-0.769; P=0.016), and average thigh circumference (AUC 0.630, 95% CI 0.511-0.750; P=0.033) had statistically significant but poor AUC values.

CONCLUSIONS

Preoperative ultrasound measurements of the bilateral BB can fairly predict frailty in patients scheduled for total knee arthroplasty.

Clinical effects of bacteremia in sepsis patients with community-acquired pneumonia

BACKGROUND

Data regarding the clinical effects of bacteremia on severe community-acquired pneumonia (CAP) are limited. Thus, we investigated clinical characteristics and outcomes of severe CAP patients with bacteremia compared with those of subjects without bacteremia. In addition, we evaluated clinical factors associated with bacteremia at the time of sepsis awareness.

METHODS

We enrolled sepsis patients diagnosed with CAP at emergency departments (EDs) from an ongoing nationwide multicenter observational registry, the Korean Sepsis Alliance, between September 2019 and December 2020. For evaluation of clinical factors associated with bacteremia, we divided eligible patients into bacteremia and non-bacteremia groups, and logistic regression analysis was performed using the clinical characteristics at the time of sepsis awareness.

RESULT

During the study period, 1,510 (47.9%) sepsis patients were caused by CAP, and bacteremia was identified in 212 (14.0%) patients. Septic shock occurred more frequently in the bacteremia group than in the non-bacteremia group (27.4% vs. 14.8%; p < 0.001). In multivariable analysis, hematologic malignancies and septic shock were associated with an increased risk of bacteremia. However, chronic lung disease was associated with a decreased risk of bacteremia. Hospital mortality was significantly higher in the bacteremia group than in the non-bacteremia group (27.3% vs. 40.6%, p < 0.001). The most prevalent pathogen in blood culture was Klebsiella pneumoniae followed by Escherichia coli in gram-negative pathogens.

CONCLUSION

The incidence of bacteremia in severe CAP was low at 14.0%, but the occurrence of bacteremia was associated with increased hospital mortality. In severe CAP, hematologic malignancies and septic shock were associated with an increased risk of bacteremia.

Unmet Needs and Barriers in Providing Hospital Care for Older Adults: A Qualitative Study Using the Age-Friendly Health System Framework

Purpose

This study aims to identify unmet needs and barriers for improving inpatient care for older adults at an academic hospital in Korea by using a qualitative focus group design and the Age-Friendly Health Systems (AFHS) framework.

Patients and Methods

A total of 14 healthcare providers and employees participated in focus group interviews. Participants included medical doctors, registered nurses, a receptionist, a patient transporter, a pharmacist, a physical therapist, and a social worker. The data were analyzed qualitatively, as per the Consolidated Criteria for Reporting Qualitative Research guidelines. The analysis method encompassed a thematic framework analysis via the AFHS 4Ms framework, consisting of the four domains "What Matters", "Medication", "Mentation", and "Mobility".

Results

Multiple barriers and unmet needs were identified using the AFHS 4Ms framework in the provision of inpatient care for older adults at the hospital. The main barriers identified in the "What matters" domain are a lack of shared decision-making and individualized care plans, as well as economic and safety-conscious preferences among some older patients. In the "Medications" domain, the main barriers to providing adequate and safe pharmacotherapy include patient and caregiver-related factors, increased complexity of medication use, and lack of institutional support systems. In the "Mentation" domain, the main issues identified are communication barriers related to patients, caregiver factors, and insufficient delirium management due to a lack of adequate processes/environments such as delirium identification. In the "Mobility" domain, the main challenges include reduced mobility and geriatric complications, unnecessary mobility restrictions, and the increased risk of falls due to lack of resources and environmental factors.

Conclusion

The study highlighted the need for improvements in inpatient care for older adults at an academic hospital in Korea. Identified unmet needs and barriers can be used to guide a more patient-centered approaches for an age-friendly inpatient environment.

Chronic cavitary pulmonary aspergillosis: Serial clinical and CT findings correlated with antifungal treatment and patient response

BACKGROUND

Chronic cavitary pulmonary aspergillosis (CCPA) is the most common form of chronic pulmonary aspergillosis.

OBJECTIVE

We hypothesise that by observing serial clinical and CT findings of CCPA patients with antifungal therapy, factors helping predict responses to antifungal therapy could be withdrawn.

METHODS

A total of 31 patients with CCPA who received antifungal therapy for greater than six months and who had serial CT studies were included. Clinical finding analyses were performed at initial and last follow-up CT acquisition dates. Clinical characteristics and CT features were compared between clinically improving or stable and deteriorating groups.

RESULTS

With antifungal therapy, neutrophil-to-lymphocyte ratio (2.66 vs. 5.12, p = .038) and serum albumin (4.40 vs. 3.85 g/dl, p = .013) and CRP (1.10 vs. 42.80 mg/L, p = .007) were different between two groups. With antifungal therapy, meaningful CT change, regardless of clinical response grouping, was decrease in cavity wall thickness (from 13.70 mm to 8.28 mm, p < .001). But baseline (p = .668) and follow-up (p = .278) cavity wall thickness was not different between two groups. In univariate analysis, initial maximum diameter of cavity (p = .028; HR [0.983], 95% CI [0.967-0.998]) and concurrent NTM infection (p = .030; HR [0.20], 95% CI [0.05-0.86]) were related factors for poor clinical response.

CONCLUSIONS

With antifungal therapy, cavities demonstrate wall thinning. Of all clinical and radiological findings and their changes, initial large cavity size and concurrent presence of NTM infection are related factors to poor response to antifungal therapy.

Validation of clinical frailty scale in Chinese translation

BACKGROUND

Identification of frailty is crucial to guide patient care for the elderly. The Clinical Frailty Scale (CFS) is a reliable, synthesis and clinical judgment-based tool. However, a validated Chinese version of CFS (CFS-C) is lacking. The aim of this study is to describe the translation process of CFS into traditional Chinese and to evaluate its reliability and validity in a geriatric study population in Taiwan.

METHODS

This cross-sectional study recruited 221 geriatric outpatients aged 65 years or older at a medical center in Taipei, Taiwan. The Chinese version of CFS was produced following Brislin's translation model. Weighted kappa for agreement and Kendall's tau for correlation were used to assess inter-rater reliability (a subgroup of 52 outpatients) between geriatricians and one research assistant, and validity tests (221 outpatients) by comparing CFS-C with Fried frailty phenotype and Frailty Index based on Comprehensive Geriatric Assessment (FI-CGA). Correlation between CFS-C and other geriatric conditions were also assessed.

RESULTS

The inter-rater reliability revealed moderate agreement (weighted kappa = 0.60) and strong correlation (Kendall's tau = 0.67). For criterion validity, CFS-C categorisation showed fair agreement (weighted kappa = 0.37) and significant correlation (Kendall's tau = 0.46) with Fried frailty phenotype, and higher agreement (weighted kappa = 0.51) and correlation (Kendall's tau = 0.63) with FI-CGA categorisation. CFS-C was significantly correlated with various geriatric assessments, including functional disability, physical performance, hand grip, comorbidity, cognition, depression, and nutrition status. No significant correlation was found between CFS-C and appendicular muscle mass.

CONCLUSIONS

The CFS-C demonstrated acceptable validity and reliability in Chinese older adults in Taiwan. Development of CFS-C enhanced consistency and accuracy of frailty assessment, both in research and clinical practice.

Operationalization of the Clinical Frailty Scale in Korean Community-Dwelling Older People

Background

The Clinical Frailty Scale (CFS) is a simple measure of global fitness validated in various populations in real-world settings. In this study, we aimed to assess the characteristics and validities of the CFS in community-dwelling older people in Korea, with the original classification tree (oCFS) and a culturally modified tree (mCFS).

Methods

The comprehensive geriatric assessment records of 1,064 individuals of the Aging Study of the Pyeongchang Rural Area were used for this study. For mCFS, we considered the dependency of the food preparations and household chores not to be deficits in the male population. The frailty index was used as a reference for construct validity. We used a composite outcome of death and institutionalization for outcome validity.

Results

The correlation coefficients with frailty index were higher in mCFS (.535) than in oCFS (.468). The mean frailty index was lower in individuals reclassified by mCFS (5 to 4) than people who stayed in mCFS 5. The classification coefficient of mCFS was significantly higher than that of oCFS (p <0.001) in determining people with frailty (frailty index.25 or higher). Trends of a higher incidence of the composite outcome were observed in both higher oCFS and mCFS, in which oCFS and mCFS did not differ significantly in predicting the risk of the outcome.

Conclusion

The classification tree of CFS could be culturally adopted in a community-dwelling population of Korea and considered valid in detecting the vulnerable population.

Preoperative Fall Risk Assessment Score as a Prognostic Factor in Esophageal Cancer Patients after Esophagectomy

The current study investigated the impact of preoperative fall risk assessment score (FRAS) on long-term prognoses in patients with esophageal cancer (EC). A total of 161 patients with EC who underwent curative surgery were classified into a high-risk (95, 41.0%) and low-risk (66, 41.0%) groups according to their FRAS. This study investigated the relationships between the FRAS and clinicopathological findings and prognoses. Accordingly, patients in the high-risk group were significantly older and had a significantly higher Charlson comorbidity index than those in the low-risk group. No significant difference was found in pathological findings between both groups. The high-risk group had significantly lower overall survival (OS) and relapse-free survival (RFS) rates than the low-risk group (p = 0.004 and 0.001, respectively). Multivariate analysis identified high FRAS as an independent prognostic factor for poor OS, with a hazard ratio of 1.75 (p = 0.033). Moreover, re-analysis of the data after excluding age as a category showed that the high-risk group had significantly worse OS (p = 0.004) and RFS (p = 0.003) than the low-risk group. The FRAS can, therefore, be considered a useful method for assessing frailty and a potential prognostic factor for EC.

Validation of the revised 9-scale clinical frailty scale (CFS) in Greek language

BACKGROUND

Among many screening tools that have been developed to detect frailty in older adults, Clinical Frailty Scale (CFS) is a valid, reliable and easy-to-use tool that has been translated in several languages. The aim of this study was to develop a valid and reliable version of the CFS to the Greek language.

METHODS

A Greek version was obtained by translation (English to Greek) and back translation (Greek to English). The "known-group" construct validity of the CFS was determined by using test for trends. Criterion concurrent validity was assessed by evaluating the extent that CFS relates to Barthel Index, using Pearson's correlation coefficient. Both inter-rater and test-retest reliability were assessed using intraclass correlation coefficient.

RESULTS

Known groups comparison supports the construct validity of the CFS. The strong negative correlation between CFS and Barthel Index (rs = - 0,725, p ≤ 0.001), supports the criterion concurrent validity of the instrument. The intraclass correlation was good for both inter-rater (0.87, 95%CI: 0.82-0.90) and test-retest reliability (0.89: 95%CI: 0.85-0.92).

CONCLUSION

The Greek version of the CFS is a valid and reliable instrument for the identification of frailty in the Greek population.

Geriatrics Fact Sheet in Korea 2021

South Korea became an aged society in 2017 and is predicted to become a super-aged society by 2025. Therefore, knowing the trends among older adults and identifying the geriatric burden are crucial for both healthcare professionals and policymakers. We previously summarized the general health and socioeconomic profiles of Korean older adults from the 2017 National Survey of Living Conditions and Welfare Needs of Older Koreans. In this update, we briefly summarized the results of the 2020 National Survey of Living Conditions and Welfare Needs of Older Koreans by categorizing them according to their general aging profile, socioeconomic status, lifestyle, and health status. In addition, we reviewed recent updates in the field of frailty and sarcopenia from population-based community cohorts in Korea. We hope this study will serve as a current reference for nationwide statistical data on common clinical and social parameters used in geriatrics and gerontology.
