Key result
Rising peri-operative risk was independently associated with increased 1-year mortality after cardiac surgery (5.6% vs 3.5%; OR 2.6, 95% CI 2.2-3.0, p<0.001).

Dynamic peri-operative risk assessment may identify patients requiring closer postoperative surveillance; leaves open whether targeted.

Does rising peri-operative acute risk change increase one-year mortality in cardiac surgical patients?
Odds Ratio: 2.6 (95% CI 2.2–3)
Absolute Event Rate: 5.6% vs 3.5%
p-value: p=< 0.001
An increase in calculated mortality risk between the pre- and postoperative periods of cardiac surgery is strongly associated with increased 1-year mortality and shorter long-term survival.
Coulson et al. (2017) conducted a cohort in Cardiac surgery (n=22,570). Rising risk (increase in risk from pre- to postoperative phase) vs. No rising risk was evaluated on one-year mortality (OR 2.6, 95% CI 2.2-3.0, p=< 0.001). Rising peri-operative risk was independently associated with increased 1-year mortality after cardiac surgery (5.6% vs 3.5%; OR 2.6, 95% CI 2.2-3.0, p<0.001).
