Local diagnostic reference levels for angiographic and fluoroscopic procedures: Australian practice

In plain language

One Australian teaching hospital used 11,000 angiographic and fluoroscopic examinations to propose local patient-dose reference levels (75th percentile dose area product). These describe patient dose, not staff dose, though they may support dose-optimisation benchmarking.

Summary based on: the abstract

What it found

Local diagnostic reference levels were proposed for a wide range of diagnostic and interventional angiographic and fluoroscopic procedures using data from one Australian teaching hospital.
Key figures: 11,000 examinations over 2.5 years
LDRLs were set at the 75th percentile of dose area product, with median fluoroscopy times also reported; each procedure type had at least 50 cases.
Key figures: 75th percentile dose-area product (DAP); minimum 50 cases per procedure
Australia lacked national diagnostic reference levels (DRLs) for fluoroscopic procedures; these local levels may guide other institutions and inform the national regulator.

Limits to keep in mind

Single-centre data from one Australian public teaching hospital, so the levels may not generalise; the abstract reports patient dose metrics only, not staff dose, and gives no actual DRL values.
