How it works

The SMR is calculated as observed hospital deaths divided by expected hospital deaths for an ICU in a year. — Mortality differences between ICUs that are regarded as ‘in control’: a longitudinal register-based study in the Netherlands, 2013–2023
For each ICU-year, expected deaths were calculated by summing individual APACHE-IV predicted mortality risks. — Mortality differences between ICUs that are regarded as ‘in control’: a longitudinal register-based study in the Netherlands, 2013–2023
Expected hospital deaths are based on risk-adjusted mortality predictions, especially the APACHE-IV model. — Mortality differences between ICUs that are regarded as ‘in control’: a longitudinal register-based study in the Netherlands, 2013–2023
Observed hospital mortality increased across SMR categories in the study population. — Mortality differences between ICUs that are regarded as ‘in control’: a longitudinal register-based study in the Netherlands, 2013–2023
