Table 2 Impact of patient characteristics on death at discharge and rescue. Hazard ratios for death at discharge and rescue obtained from Cox’s proportional hazards model were calculated for each feature within a category using reference characteristics. Hazard ratios, adjusted for controlling for age, sex, marital and surgical/non-surgical patient status, are presented along with confidence intervals and p values. Only the five MDC-DRGs with the highest hazard ratios are shown
