Abstract Background Long-term survival is an important metric in assessing procedural value. We previously confirmed that the Society of Thoracic Surgeons predicted risk of mortality score (PROM) accurately predicts 30-day mortality in Israeli patients. The present study investigated the ability of the PROM to reliably predict long-term survival. Methods Data on 1279 patients undergoing cardiac surgery were prospectively entered into our database and used to calculate PROM. Long-term mortality was obtained from the Israeli Social Security Database. Patients were stratified into five cohorts according to PROM (A: 0–0.99%, B: 1.0–1.99%, C: 2.0–2.99%, D: 3.0–4.99% and E: ≥ 5.0%). Kaplan–Meier estimates of survival were calculated for each cohort and compared by Wilcoxon signed-rank test. We used C-statistics to assess model discrimination. Cox regression analysis was performed to identify predictors of long-term survival. Results Follow-up was achieved for 1256 (98%) patients over a mean period of 62 ± 28 months (median 64, range 0–107). Mean survival of the entire cohort was 95 ± 1 (95% CI 93–96) months. Higher PROM was associated with reduced survival: A—104 ± 1 (103–105) months, B—96 ± 2 (93–99) months, C—93 ± 3 (88–98) months, D—89 ± 3 (84–94) months, E—74 ± 3 (68–80) months (p |
