Statistics Netherlands has calculated The Hospital Standardised Mortality Ratios (HSMRs) for Dutch hospitals for the period 2020-2022. This report describes the methods that were used.
In chapter 2 the changes compared to previous HSMR calculations are described. The largest change in the present HSMR model is that for reporting year 2022 the admissions with COVID-19 as main diagnosis have been included. COVID-19 admissions of 2020 and 2021 are excluded from the HSMR 2020-2022, like in previous HSMR calculations.
In chapter 4 the quality of the present HSMR model is evaluated and the effect of including COVID-19 admissions on the HSMRs 2022 is described.
For the report see ‘HSMR 2022 Methodological report’ in the ‘Downloads’ beneath.
Excel file ‘Classification of variables HSMR 2022’ contains the classifications used for the diagnosis groups, severity of main diagnosis, socio-economic status and source of admission.
Excel file ‘Coefficients HSMR 2022’ contains the coefficients and standard errors of the HSMR model by diagnosis group.
HSMR 2022 outcomes are published by the hospitals (31 December 2023 at the latest), on the websites of the individual hospitals.
