To critically examine the mortality rates of septic shock over the last 25 years to determine if significant improvements have been accomplished. ⋯ Survival rates for patients in septic shock have gradually improved in critical care units worldwide over the last 25 years. Further improvement will be predicated on the discovery of new therapies to disrupt the underlying pathophysiology of sepsis and the development of improved rapid, diagnostic testing and immune monitoring of individual patients.

ReviewOutcome prediction in critical care: the Simplified Acute Physiology Score models.
Outcome prediction models measuring severity of illness of patients admitted to the intensive care unit should predict hospital mortality. This review describes the state-of-the-art of Simplified Acute Physiology Score models from the clinical and managerial perspectives. Methodological issues concerning the effects of differences between new samples and original databases in which the models were developed are considered. ⋯ Comparisons of intensive care unit performance should take into account not only the patient severity of illness, but also the effect of the 'intensive care unit variable', that is, differences in human resources, structure, equipment, management and organization of the intensive care unit. In the future, moving from patient and geographical area adjustment to resource use could allow the user to adjust for differences in healthcare provision.
