Hospital Readmission Ratio: Methodological report 2023

Statistics Netherlands has updated the model (2023) to derive hospital readmission ratios for Dutch hospitals, adjusted for case mix differences.

This report describes the methods that were used for the 2023 model and the outcome of the evaluation of this model. The model is calculated using data from the Dutch hospital discharge register ‘Landelijke Basisregistratie Ziekenhuiszorg (LBZ)’ of DHD.

The following files are made available as downloads in the Appendix: the file ‘Appendix I: Results of the logistic regressions’ presents the statistical significance (95% confidence) of the covariates for the 123 logistic regression. The file ‘Appendix II: AUC’ presents the AUC or C-statistic for the logistic regressions of the 123 main diagnosis groups.

The variables used in the readmission model are the same as used in the model for the Hospital Standardised Mortality Ratio (HSMR), published by Statistics Netherlands. For the classification of these variables we therefore refer to the file ‘Classification of variables HSMR 2023’ in the appendix of the ‘HSMR methodological report 2023’ (listed in the references of this report).
