Jepma P, Verweij L, Tijssen A, et al. - This study was attempted to calculate the performance of the Dutch Safety Management System (DSMS-tool) alone and combined with other predictors in predicting hospital readmission or mortality within 6 months in acutely hospitalized older cardiac patients. Researchers conducted an individual patient data meta-analysis on 529 acutely hospitalized cardiac patients ≥ 70 years from four prospective cohorts. In this study, shrunk c-statistics, calibration plots, regression slopes, and Hosmer-Lemeshow p-values were used to evaluate predictive performance in terms of discrimination and calibration. The findings revealed that in hospitalized older cardiac patients, DSMS-tool alone has limited capacity to accurately estimate the risk of readmission or mortality. It was shown that adding disease-specific risk factor information to the DSMS-tool resulted in a moderately performing model. The combination of geriatric and disease-specific predictors should be further explored to optimize the early identification of older hospitalized cardiac patients at high risk.
