Hospital readmission ratio models 2016

Models (2016) to derive hospital readmission ratios for Dutch hospitals, adjusted for case mix differences. This report describes the methods that were used for the 2016 models and the outcome of the evaluation of these models. The models are calculated using data from the Dutch hospital discharge register ‘Landelijke Basisregistratie Ziekenhuiszorg (LBZ)’ of DHD.

Unlike previous year, two models have been produced: a model for readmissions within the same hospital (intra-hospital model), and a model that also includes readmissions in other hospitals (inter-hospital model).
Excel files ‘coefficients intra-hospital model.xlsx’ and ‘coefficients inter-hospital model.xlsx’ contain per diagnosis group the coefficients and standard errors of the models.

The variables used in the readmission models are the same as used in the model for the Hospital Standardised Mortality Ratio (HSMR), published by Statistics Netherlands, see file ‘Classification of variables HSMR 2016’ and ‘HSMR methodological report 2016’ underneath.
