Relative proportion of deaths in hospital for a specific intervention or disease per hospital.
The hospitals sometimes treat groups of patients with different case severity. Therefore, the FOPH determines a rate of expected deaths per hospital and procedure. For the quality comparison, we use the ratio between the expected and the actually observed deaths (per intervention and per hospital). This is called risk adjustment. For this reason, it can occasionally happen that a hospital performs better in the ranking even though it has a slightly higher percentage of deaths.
Please note that we use the FOPH data per hospital site in order to achieve the most precise statements possible.
