Calculation: Description |
The indicator is expressed as a rate of obstetric traumas per 100 unassisted vaginal deliveries. Risk-adjusted rate = Observed cases ÷ Expected cases × Canadian average Unit of analysis: Single admission |

Rationale |
Obstetric trauma is among the most common adverse events in Canada. Obstetric trauma, including third-degree lacerations and greater in severity, may result in longer lengths of stay for mothers and chronic complications such as fecal incontinence, dyspareunia, perineal pain and other pelvic floor disorders. Risk factors for obstetric trauma include maternal age, large fetal size, prolonged pregnancy, long labour, malposition, episiotomy extraction and instrument assistance. The obstetric trauma indicators are intended to be used as flags to identify areas for improvement and to help identify processes of care that require hospital-level evaluation. |

Lower rates are desirable. |
