Purpose Frailty is a valuable predictor for outcome in elderly ICU patients, and has been suggested to be used in various decision-making processes prior to and during an ICU admission. There are many instruments developed to assess frailty, but few of them can be used in emergency situations. In this setting the clinical frailty scale (CFS) is frequently used. The present study is a sub-study within a larger outcome study of elderly ICU patients in Europe (the VIP-2 study) in order to document the reliability of the CFS. Materials and methods From the VIP-2 study, 129 ICUs in 20 countries participated in this sub-study. The patients were acute admissions ≥ 80 years of age and frailty was assessed at admission by two independent observers using the CFS. Information was obtained from the patient, if not feasible, from the family/caregivers or from hospital files. The profession of the rater and source of data were recorded along with the score. Interrater variability was calculated using linear weighted kappa analysis. Results 1923 pairs of assessors were included and background data of patients were similar to the whole cohort (n = 3920). We found a very high inter-rater agreement (weighted kappa 0.86), also in subgroup analyses. The agreement when comparing information from family or hospital records was better than using only direct patient information, and pairs of raters from same profession performed better than from different professions. Conclusions Overall, we documented a high reliability using CFS in this setting. This frailty score could be used more frequently in elderly ICU patients in order to create a more holistic and realistic impression of the patient´s condition prior to ICU admission.

“…As frailty has been associated with mortality [ 6 , 10 , 11 ], length of hospitalization [ 24 – 26 ], degree and time of recovery [ 12 , 27 ], re-admission [ 11 , 25 , 28 ], and future need for institutionalization [ 6 , 24 , 29 ], there is a need for tools that can be used practically and quickly to detect frailty [ 30 ]. In order to avoid misclassification due to differences in culture or how someone perceives the English version individually [ 31 ], CFS has been translated in several languages [ 30 – 36 ]. Trying to promote the adequate use of this scale in Greece we aimed to develop a valid and reliable version of the CFS to the 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.

“…A major strength of this study is the comparison of patients presenting with suspected COVID-19 and subsequent positive SARS-CoV-2 PCR swab tests to patients with similar symptoms but negative swab tests. With the Clinical Frailty Scale, we used a validated tool with good interrater reliability [8][9][10][11][12]. Since all patients aged 65 years and older with suspected COVID-19 infection and frailty level assessment were included, we minimised the risk of a selection bias.…”

“…Frailty, on the other hand, appears to be a predictor for adverse outcomes in hospitalised COVID-19 patients [4][5][6][7]. The Clinical Frailty Scale (CFS) is a validated tool to assess frailty, and has already been implemented in emergency settings [8][9][10][11][12]. There is a debate if frailty could be of higher prognostic importance than age [13][14][15][16][17][18].…”

Older age and frailty are predictors of adverse outcomes in patients with COVID-19. In emergency medicine, patients do not present with the diagnosis, but with suspicion of COVID-19. The aim of this study was to assess the association of frailty and age with death or admission to intensive care in patients with suspected COVID-19. This single-centre prospective cohort study was performed in the Emergency Department of a tertiary care hospital. Patients, 65 years and older, with suspected COVID-19 presenting to the Emergency Department during the first wave of the pandemic were consecutively enrolled. All patients underwent nasopharyngeal SARS-CoV-2 PCR swab tests. Patients with a Clinical Frailty Scale (CFS) > 4, were considered to be frail. Associations between age, gender, frailty, and COVID-19 status with the composite adverse outcome of 30-day-intensive-care-admission and/or 30-day-mortality were tested. In the 372 patients analysed, the median age was 77 years, 154 (41.4%) were women, 44 (11.8%) were COVID-19-positive, and 125 (33.6%) were frail. The worst outcome was seen in frail COVID-19-patients with six (66.7%) adverse outcomes. Frailty (CFS > 4) and COVID-19-positivity were associated with an adverse outcome after adjustment for age and gender (frailty: OR 5.01, CI 2.56–10.17, p < 0.001; COVID-19: OR 3.47, CI 1.48–7.89, p = 0.003). Frailty was strongly associated with adverse outcomes and outperformed age as a predictor in emergency patients with suspected COVID-19.
