Definition of abbreviation: ICD-9-CM = International Classification of Diseases, Ninth Revision, Clinical Modification.
Sepsis accounted for 4.4% of admissions, yet it accounted for 44.7% of the 2,545 in-hospital deaths (1,138 of 2,545). Sepsis categories presented were not mutually exclusive. For example, 503 admissions at risk for readmission received the ICD-9-CM–specific code for sepsis and were identified using the combined end-organ dysfunction and infection approach, and 1,772 admissions at risk for readmission received the ICD-9-CM–specific code for severe sepsis and were identified using the combined end-organ dysfunction and infection approach.
Post–acute care use includes home health services and skilled care facility placement (e.g., acute rehabilitation, long-term acute care hospital, skilled nursing facility).
