Description of intervention(s) / exposure
This is a retrospective cohort study: The exposure is peak temperature in the first 24 hours of intensive care admission and this will be treated as a categorical variable, divided into 0.5 degrees celsius increments. We will report odds ratios for risk of death relative to normal temperature defined as the range from 36.0 degrees to 37.5 degrees celcius.

The outcome reported in the retrospective database is mortality at hospital discharge.

The study will include all patients admitted to an adult ICU at one of 129 centres in Australia and New Zealand (ANZ) or one of 201 centres in the United Kingdom (UK) between 2005 and 2010.
