- Primary Outcome Measures
Name Time Method 30-day mortality 30-days Mortality within 30 days of surgery in each of the three frailty risk groups
Time to hospital readmission Up to 180 days For patients surviving index hospitalization, the proportional hazard ratio of readmission between the three frailty group
- Secondary Outcome Measures
Name Time Method Prolonged hospital length-of stay 3 months Incidence of patients staying more than 10-days after surgery in the three frailty risk cohorts
Long-term mortality Up to 14 years Long-term mortality of the three different frailty risk groups, compared with proportional hazard modeling
