Dose differences related to access
| Radial | Femoral | Other | p-value | |
|---|---|---|---|---|
| N= | 5426 | 2020 | 180 | |
| Age (years) | 66 (57–73) | 72 (63–80) | 58 (46–65) | <0.001 |
| BMI(kg/m2) | 29.4 (25.7–33.7) | 28.7 (24.9–32.9) | 28.1 (24.2–31.6) | <0.001 |
| Male Gender | 3603 (66%) | 1370 (68%) | 121 (67%) | 0.509 |
| DAP (Gycm2) | 23.4 (13.0–42.1) | 30.6 (15.7–54.4) | 3.7 (1.5–7.3) | <0.001 |
| RTD (µSv) | 8 (3–21) | 5 (2–13.5) | 2 (0–6) | <0.001 |
| E (µSv) | 0.4 (0.1–1.0) | 0.3 (0.1–0.6) | 0.1 (0.0–0.3) | <0.001 |
| RTD/DAP(µSv/Gycm2) | 0.3 (0.1–0.8) | 0.2 (0.1–0.4) | 0.4 (0–2.5) | <0.001 |
BMI, body mass index; DAP, dose area product; E, calculated effective dose; RTD, real time digital dosimeter reading.
This table demonstrates the differences in radiation dose measures in relation to catheter access route and demonstrates that operator dose is generally higher for radial access but the effective dose normalised to DAP (RTD/DAP) ratio is highest with ‘other’ access routes
