Description of intervention(s) / exposure
Using data obtained from the Australian & New Zealand Society of Cardiac & Thoracic Surgeons (ANZSCTS) registry we retrospectively collect participant demographics, surgical characteristics, hospital care interventions and complications for the 'after period' which associated amino acid therapy. Specifically, data will be collected annually for the future 3-year period: 1st January 2025 until 31st December 2027.

Comparator / control treatment
Using data obtained from the Australian & New Zealand Society of Cardiac & Thoracic Surgeons (ANZSCTS) registry we retrospectively collect participant demographics, surgical characteristics, hospital care interventions and complications for the 'before period' which did not involve the administration of amino acid therapy for the 3 years: 1st January 2022 to 31st December 2024.

Outcomes
Primary outcome [1] 339857 0
The occurrence of acute kidney injury within the first week after cardiac surgery, with acute kidney injury defined according to the Kidney Disease: Improving Global Outcomes (KDIGO) criteria for stage 1 or greater acute kidney injury. Stage 1 acute kidney injury is defined as an increase in the serum creatinine level of at least 0.3 mg per decilitre (26.5 micromol per litre) during a 48-hour period or a 50% increase from baseline during a 1-week period, stage 2 as a doubling of the baseline serum creatinine level, and stage 3 as a tripling of the baseline serum creatinine level or the initiation of dialysis, with either occurring within 1 week after the insult (e.g., cardiac surgery).

Statistical methods / analysis
Analysis following data-linkage will be led by bio-statistician proficient in the analysis of large data sets. Statistical analyses will be performed using R version 4.4.0 (R Foundation for Statistical Computing). Baseline characteristics will be reported as frequencies and percentages, means ? standard deviation, or medians and interquartile ranges. Summary statistics to compare baseline characteristics will include t-test, chi squared test, Fisher exact test, and Wilcoxon rank sum test, as dictated by data type. The primary outcome will be reported using multivariable mixed effects linear regression models. Secondary outcomes will be explored using multivariable linear regression models for continuous outcomes and logistic regression models for binary outcomes. No imputation will be performed for missing data. A two-sided p-value <0.05 will be considered significant.
