## Transplanting Hospital Report: 2019-2024
* Summary of ANZDATA Registry Outcomes for Australia & New Zealand (Published September 2025).

## Report Scope & Methodology
* Cohort: Patients ≥16 years transplanted Jan 2019 – Dec 2024.
* Stats: Random effects logistic regression used for expected vs. observed event calculations.

## Graft Failure Outcomes (1 Year)
* Metric: Risk-Adjusted Graft Failure Ratio (return to dialysis or death within 1 year).
* Highlights: Christchurch Hospital (2.50) and St Vincent's NSW (2.23) showed higher ratios; Royal Melbourne (0.55) showed lower ratios.

## Risk Factors for Graft Failure
* Significant predictors: Donor age ≥60 years and prolonged ischaemic time (≥12 hours).

## Patient Mortality Outcomes (1 Year)
* Risk-adjusted model for deaths within 1 year post-transplant (82.6% AUC).
* Data point: Christchurch Hospital had 4 observed deaths vs 1.1 expected.

## Significant Risk Factors for Mortality
* Strongest predictor: Prolonged ischaemic time (≥12 hours) in non-CVA deceased donors (OR 2.88).
* Secondary factor: Recipient Lung Disease (OR 2.39).

## Data Visualization: Funnel Plots
* Hospitals plotted by sample size vs. observed/expected ratio with 95% confidence intervals.
* Identifies outliers that perform statistically differently than the expected mean.

## Conclusion & Recommendations
* Inferior results are 'signals' for investigation, not proof of poor care.
* Models predict ~70% of variation; results may be influenced by chance or unmeasured confounders.
