Relationship between acute physiologic derangement and risk of death.
Initial evidence from 481 acutely ill patients with 12 major life-threatening diseases suggests a consistent relationship between the magnitude of physiologic derangement and the patient's risk of death. These results were found in postoperative and nonoperative diseases, including gastrointestinal bleeding, intracranial bleeding, pneumonia, congestive heart failure, trauma and hemorrhagic shock. There appear to be substantial differences in the inherent risk of these diseases, but within each diagnosis, the impact of incremental increases in physiologic derangement on mortality appears to be similar. The existence of a uniform relationship in a variety of diagnoses could have important implications for the researcher and clinician wishing to evaluate outcome from intense medical care. It would allow more reproducible and precise stratification of patients by risk of death prior to therapy, thereby improving our understanding of the efficacy of new and existing treatments.
