Bacteraemia data are available in ANRESIS

Dataset homogenisation is challenging. Summarising individual samples into episodes can improve data comparability, but may limit direct comparison with existing literature.
Sending only positive blood culture results to the laboratory is a practical approach used by many hospitals, but it limits the completeness and interpretability of subsequent data analyses.
Larger hospitals show higher incidences of positive blood cultures and higher proportions of polymicrobial episodes, reflecting the greater complexity of their patient populations.
At the same time, larger hospitals may obtain blood cultures more readily, which may result in lower overall positivity rates.
Overall, the analysis of ANRESIS data provides valuable insights into key blood culture indicators. However, data homogenisation and clearly standardised definitions are essential for meaningful benchmarking.
