Figure 1

Frequency distribution of the total Procedural Index for Mortality Risk (PIMR) score among validation admissions. The horizontal axis presents the total PIMR score. The bars and left vertical axis presents the percent of hospitalizations with each total PIMR score. Individual PIMR scores were grouped to contain at least 0.5% of all admissions. The line and right vertical axis presents the observed number of deaths (with 95% confidence intervals) in each PIMR score.
