Treatment and study plan

Frailty risk groups

Other

Patients older than 65 will be separated into groups of varying frailty risk

Primary outcomes

  1. 30-day mortality

    Time frame: 30-days

    Mortality within 30 days of surgery in each of the three frailty risk groups

  2. Time to hospital readmission

    Time frame: Up to 180 days

    For patients surviving index hospitalization, the proportional hazard ratio of readmission between the three frailty group

Secondary outcomes

  1. Long-term mortality

    Time frame: Up to 14 years

    Long-term mortality of the three different frailty risk groups, compared with proportional hazard modeling

  2. Prolonged hospital length-of stay

    Time frame: 3 months

    Incidence of patients staying more than 10-days after surgery in the three frailty risk cohorts
