Risk-adjusted mortality is calculated as standardized mortality ratio (SMR). The indicator is highly relevant because extended survival is an obvious goal for all intensive care. Risk-adjusted mortality is also a performance measure that allows good comparability for results from different ICU and from the same ICU over time.
Risk adjustment intensive care. SAPS3 Key performance indicator
The red dot shows SMR by department. The blue bar shows the confidence interval. If blue bar is missing, it may be either because the confidence interval is less than the red dot (e.g. the whole of Sweden in a graph grouped by departments) or because the number of deceased is so low (< 20 pcs) that the confidence interval becomes large and less accurate with the method used for calculating confidence intervals (Byars approximation).
SMR based on PIM3, ICU mortality
The red dot shows SMR by department. The blue bar shows the confidence interval. Note that the calculation of confidence intervals using the method used to calculate confidence intervals (Byars approximation) becomes less accurate when the number of deaths per group is less than 20.
SMR based on ICU-Higgins 30-day mortality
The red dot shows SMR by department. The blue bar shows the confidence interval. If blue bar is missing, it may be either because the confidence interval is smaller than the red dot (for example, the whole of Sweden in a graph grouped by departments).
