Description of intervention(s) / exposure
In this study we will be observing the postoperative outcomes in patients aged 90-100 years who have been at admitted to the Intensive Care Unit (ICU) at The Austin Hospital, a university teaching institution in Melbourne, Australia, between 1 Jan 2010 and 31 December 2020.

Only the de-identified hospital medical record of patients who have been admitted to ICU will be reviewed.

The primary aims are to identify the characteristics, outcomes and mortality of nonagenarian whilst admitted to ICUs and throughout their hospital admission. The secondary aims are to explore the indicators of poor outcomes in nonagenarian patients admitted to ICU, including cause of admission, and validated risk scores.

Outcomes
Primary outcome [1] 339432 0
The primary outcome is the mortality of nonagenarian whilst admitted to ICU and throughout their hospital admission.
Timepoint [1] 339432 0
This will be calculated retrospectively from the completion of admission to ICU to death or hospital discharge for the index admission only.
Secondary outcome [1] 439968 0
The secondary outcome will be to measure the Australian and New Zealand Risk of Death (ANZROD) risk score.
Timepoint [1] 439968 0
The Australian and New Zealand Risk of Death (ANZROD) score will be calculated when the patient is admitted to ICU.
Secondary outcome [2] 440199 0
Other secondary outcomes will be to measure the Acute Physiology and Chronic Health Evaluation (APACHE) II score.
Timepoint [2] 440199 0
The APACHE II score will be calculated when the patient is admitted to ICU.
Secondary outcome [3] 440456 0
Other secondary outcomes will be to measure the Acute Physiology and Chronic Health Evaluation (APACHE III) score
Timepoint [3] 440456 0
The APACHE III score will be calculated when the patient is admitted to ICU.
Secondary outcome [4] 440457 0
Other secondary outcomes will be to measure the Glascow Coma Scale (GCS) score.
Timepoint [4] 440457 0
The GCS score will be calculated when the patient is admitted to ICU.

Statistical methods / analysis
Statistical analysis will be performed using R software 4.3.2 (R Development Core Team, Vienna, Austria, 2023). Data will de-identified and variable names were encrypted. All data will be coded numerically to maintain blinding of the collected variable characteristics for the statistician.

Data will be presented as median (interquartile range, 25%–75%) or the number of cases (percentile) for descriptive statistics. Cox regression survival analysis will be used to investigate the hazard ratios (HR) and their confidence intervals of predefined risk scores and other clinical variables influencing mortality during ICU or hospital stays. Receiver operating characteristic (ROC) curves will be used to assess the discriminatory power of risk scores in predicting survival outcomes of nonagenarians.
