Outcome Measures

Primary Outcomes (2)

  • Frailty

    Frequency of frailty is measured by modified Fried criteria (category 1 +2 = pre-frail, category 3 -5 = frail)

    Up to 1 year

  • Neuro-cognitive disorder (NCD)

    Frequency of neuro-cognitive disorder (mild / major NCD)

    Up to 1 year

Secondary Outcomes (84)

  • Incidence of delirium

    During the hospital stay, an expected average of 1 week

  • Severity of delirium

    During the hospital stay, an expected average of 1 week

  • Nursing Delirium Screening Scale (Nu-DESC)

    During the hospital stay, an expected average of 1 week

  • Confusion Assessment Method (CAM)

    During the hospital stay, an expected average of 1 week

  • Confusion Assessment Method for the Intensive Care Unit (CAM-ICU)

    During the hospital stay, an expected average of 1 week

  • +79 more secondary outcomes

Study Arms (4)

PG cohort

800 randomized surgical study patients with a frailty syndrome (Pre-frail and frail) of the intervention study PRÄP-GO (PG cohort). 400 study patients receive the intervention and 400 study patients receive standard of care.

Behavioral: Prehabilitation- new form of care

NFC cohort

400 non-frail surgical control group (NFC cohort)

NO cohort

300 non-operative control group (NO cohort)

GB cohort

Skill-Change-Management: a maximum of 30 coworkers and analysis of guiding principle: to a maximum of 35 patients, 30 relatives and 45 coworkers

Interventions

The participants in the intervention group take part in a shared decision-making (SDM) conference to plan the intervention. The therapeutic content of the prehabilitation is defined individually for each patient in the SDM conference. Prehabilitation will be a structured and individually tailored 3-week program.
