Abstract
Background: The G8 and ISAR scores are two different screening tools for geriatric risk factors and frailty. The aim of this study was to compare the G8 and ISAR screening results in a cohort of urogeriatric patients to help clinicians to better understand and choose between the two tests. Methods: We retrospectively evaluated 100 patients at the age of 75 and above who were treated for different urological conditions. All routinely and prospectively underwent G8 and ISAR screening tests. A G8 score ≤ 14 and an ISAR score > 2 were considered positive. The results for the two tests were compared and correlated to clinical data. Results: The mean age of the patients was 83 y (min. 75–max. 101); 78 of the patients were male, while 22 were female; 58 of the patients were G8-positive, while 42 were G8-negative; and 24 were ISAR-positive, while 76 ISAR were negative. All the ISAR-positive patients were also G8-positive. There was a significant negative correlation between the G8 and ISAR scores (r = −0.77, p < 0.001). Both tests correlated significantly with the Charlson comorbidity index, length of stay, number of coded diagnosis, and Braden score (p < 0.05). Conclusion: Both tests are significantly correlated with each other and to clinical data related to geriatric frailty. However, the G8 score has a much higher rate of positive tests, which limits its use in daily routine, and the ISAR score is therefore preferable. For “fit” geriatric patients, however, a negative G8 score can be of great use as a confirmatory test for further decision making.
Highlights
Because of an increased life expectancy and aging in recent years with high birth rates, geriatric aspects have become more and more important in the daily routine of urologists [1]

Summary
Because of an increased life expectancy and aging in recent years with high birth rates, geriatric aspects have become more and more important in the daily routine of urologists [1]. Most urological malignancies, such as prostate, bladder, and renal cancer, as well as urinary retention or urinary tract infections and their subsequent medical, surgical, and/or radio-oncologic treatments, affect old and very old patients [2,3] For optimal treatment, their geriatric situation should be assessed and included in medical decision making [4,5]. Among them are the G8 score and the ISAR score, which are both recommended as geriatric screening tests and are routinely performed in our department. Both tests were designed to measure geriatric frailty or geriatric risk factors for frailty. The G8 and ISAR scores are two different screening tools for geriatric risk factors and frailty. For “fit” geriatric patients, a negative G8 score can be of great use as a confirmatory test for further decision making
