Feasibility of an Extended Test Battery and Influencing Factors for Detecting Frailty

The aim of the prospective study is to assess the feasibility of a screening and baseline measurement protocol that is planned for a main study (PRÄP-GO) in a collective of 30 patients ageing 70+ scheduled for elective surgery. Comprehensive geriatric assessment scores and modified Fried frailty phenotype component evaluation are performed in all patients at baseline before elective surgery. The assessment of cognitive tests is conducted with a battery of neuropsychological tests, computer-based tests from the Cambridge Neuropsychological Test Automated Battery \[CANTAB®\] and non-computer based tests. Frailty scores from 0 to 5 (i.e., 1 point for each component; 0 = best to 5 = worst) represent robust (0), pre-frail (1-2), and frail (3-5) health status. 10 patients without Frailty, 10 patients with Pre-Frailty and 10 patients with Frailty should be analyzed in this study and receive further comprehensive geriatric assessment testing up to seven days after surgery/discharge (before 7 postoperative days).
