The patients included in PRP-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.


As part of the innovation fund project PRP-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 PRP-GO.

The groups of participants in this accompanying program ANA-PRP-GO are:

  • Randomized study patients with a frailty syndrome of the intervention study PRP-GO (PG cohort)
  • Non-frail surgical control group (NFC cohort)
  • Non-operative control group (NO cohort)
  • Participants with health professions (GB cohort)

Additionally, relatives of the patients can be included.

Subprojects are included to reflect research questions of interest in sub groups:

  • Success of endoprosthetic implants (clinical outcome and gait pattern after total hip arthroplasty and total knee arthroplasty in frail patients)
  • Functional treatment outcome and health-related quality of life after elective spinal surgery in the PG cohort, in the NFC cohort, and in the NO cohort
  • Hemodynamic evaluation in patients of the PG and NFC cohort with preoperative abnormal cardiovascular function
  • Establishment of a German standard database for 14 CANTAB tests by CANTAB Connect technology
  • Aggregated evaluation of the cognitive data of different anesthesiological study cohorts to describe domain-specific changes in the perioperative course
  • Perspectives of different health professional groups regarding necessary changes in skill, organizational and management, and communication in interdisciplinary setting and with patients and significant others.
  • Perspectives of patients and significant others regarding the organizational pathway of the prehabilitation program
  • Frequency, pathophysiology and trajectory of muscle weakness as well as functional impairments of patients admitted to intensive care units of the PG and NFC cohort and their long-term outcomes.
  • The gut microbiome as a potential risk factor for perioperative neurocognitive disorders (PNDs) in the elderly
  • Evaluation of nutrition data in all cohorts (e.g. adherence to mediterranean diet, nutrition habits, nutritional status etc.)
