Rates of abuse across the three healthcare environments.
| Healthcare environment | Antenatal clinic n = 482 | Emergency department n = 495 | Three general practices n = 449 | Overall n = 1452 |
|---|---|---|---|---|
| Abuse within 1 year (%) | 13 (2.7) | 27 (5.5) | 26 (5.5) | 66 (4.6) |
| Age standardised assault ratio/year (95% CI) | 0.5 (0.3 to 0.9) | 1.1 (0.7 to 1.6) | 1.4 (0.9 to 2.0) | 1 (ref) |
| Abuse ever (%) | 112 (23.3) | 132 (26.7) | 139 (29.3) | 383 (26.4) |
The standardised assault ratios use indirect standardisation, and are analogous to the standardised mortality ratios. CIs were calculated using the Poisson distribution. ref = reference.
