NCT06770738

Brief Summary

We aim to compare the performances of the European System for Cardiac Operative Risk Evaluation (EuroSCORE-II) and the PreOperative Score to Predict Postoperative Mortality (POSPOM) in predicting in-hospital mortality among patients undergoing on-pump cardiac surgery, with further evaluation of discrimination, calibration, agreement, and clinical utility. This retrospective observational study will be conducted at a single tertiary university cardiac surgery centre. Adult patients (≥18 years) who underwent coronary artery bypass grafting, valve surgery, or combined procedures between 2020 and 2024 will be included. No experimental interventions will be applied. Preoperative EuroSCORE-II and POSPOM values will be calculated for all patients. Discrimination will be assessed using ROC and precision-recall curves with DeLong's test. Calibration will be evaluated using calibration-in-the-large, calibration slope, Hosmer-Lemeshow testing, and GiViTI calibration belts. Agreement will be analyzed using ICC, CCC, Bland-Altman plots, and Passing-Bablok and Deming regression. Subgroup analyses will be performed by age and sex.

Outcome Measures

Primary Outcomes (1)

  • investigation whether the POSPOM score has sufficient predictive power for in-hospital mortality in patients undergoing cardiac surgery

    The primary objective of this study was to investigate whether the POSPOM score has sufficient predictive power for in-hospital mortality in patients undergoing cardiac surgery. Measure Type: Continuous Unit of Measure: ROC-AUC Minimum: 0.50 Maximum: 1.00 Description of Meaningful Outcome: Predictive performance will be considered clinically meaningful if the ROC-AUC of the POSPOM score for in-hospital mortality is significantly greater than 0.50.

    1 month

Secondary Outcomes (1)

  • Correlation of EuroSCORE-II and POSPOM

    15 days

Study Arms (1)

Operation group

Patients aged 18 and over, patients who have CABG surgery, valve surgery or both, and patients with on-pump surgery in 2020-2024 will be included in the study. The sample size was calculated as 314 with an effect size of 0.2, 95% power and 0.05 error level using the G Power 3.1.9.2 package program, taking into account the study of Kaplan et al.

Other: There is no intervention in this study.

Interventions

This study is planned as a retrospective study. Only the information of the patients will be used.
