Utility of GERAADA Score for Predicting Long-Term Survival Following Surgical Repair of Aortic Dissection

The article aimed to assess the long-term survival outcomes following surgical repair in patients with type A aortic dissection (ATAAD) and to evaluate the correlation with the preoperative German Registry for Acute Type A Aortic Dissection (GERAADA)-score value. The authors enrolled patients from nine hospitals. Follow-up information was obtained by matching the clinical patient data with a national administrative database. A total of 1,110 patients were analyzed. The median age was 67 years (IQR 57–75), and females comprised 30.8 percent of the cohort. The median GERAADA score was 14.3 percent (10.2–22]). The mean length of follow-up was 4.19 years. Discrimination was poor but remained stable over time (AUC at 1-year follow-up: 0.66; 95 percent CI 0.63–0.70; AUC at 10-year follow-up: 0.64; 95 percent CI 0.61–0.68). Calibration plots showed under-prediction until a 50 percent predicted probability and progressive over-prediction afterward. There was a steep mortality rate in the first couple of months after surgery, while afterward, the mortality rate was constantly lower. The GERAADA-score was found to be a predictor of long-term mortality with a nonlinear association.
