The patients included in PRÄP-GO and the corresponding comparison cohorts will be offered to participate in this complementary study in order to be able to carry out a detailed characterization and phenotyping of the frailty complex.
Amendment vote of 08/05/2024: Recruitment extension of Non-frail surgical control group (NFC cohort) until August 31, 2025.
As part of the innovation fund project PRÄP-GO (EA1/225/19), a multimodal intervention is being conducted in patients with a frailty syndrome. However, the health care research project is limited to evaluating clinical issues only. In order to be able to research further pathophysiological, clinical, psychosocial and work-organizational connections, different groups of participants will be offered the participation in this scientific support program of PRÄP-GO.
The groups of participants in this accompanying program ANA-PRÄP-GO are:
Additionally, relatives of the patients can be included.
Subprojects are included to reflect research questions of interest in sub groups:
