  1. The study cohort was divided into age strata based on age qualification for Medicare. Insurance categories were determined based on primary and secondary payers identified by the data source (see Methods). Numbers represent totals from the full weighted sample and are presented as factors of 103. Percentages are based on insurance category by age stratum (unless otherwise indicated). Categorization of co-morbidity index was based upon preliminary analyses examining best fit with odds of sepsis. Severe sepsis and septic shock was categorized as a sepsis-associated admission with ICD-9 codes for any organ failure or for shock, respectively.
