Registration status: | Australian Commission on Safety and Quality in Health Care, Standard 07/06/2017 |
Description: | Number of women who have a third or fourth degree perineal laceration after giving birth vaginally, age standardised. Data are disaggregated by the area in which the mother lives. |
Rationale: | Third and fourth degree perineal lacerations cause significant ongoing maternal morbidity. This is an outcome indicator that measures their occurrence. |

Postpartum perineal status
Presented as a number per 1,000 women. Rates are directly age standardised to the 2001 Australian female population aged 15–44, using the age groups: 15-19, 20-24, 25-29, 30-34 and 35-44. For more information about age-standardisation in general see /content/index.phtml/itemId/327276
Analysis by Statistical Area Level 3 (SA3) is based on usual residence of the mother.

Disaggregation: | SA3 by :
State and territory by:
Cells of less than 5 have been suppressed. This is the lowest level of suppression that all states and territories have agreed to for the release of data from the National Perinatal Data Collection. Crude rates have been suppressed where the denominator is less than 100, for reliability purposes. The corresponding age standardised rate has also been suppressed in these cases. In addition, age standardised rates have been suppressed where the denominator for any age-stratified groups have fewer than 10 individuals. | ||||||||||||||

Comments: | Data elements are from the Perinatal national minimum data set (NMDS) or have been provided as voluntary non-standardised items by the states and territories. Records with data that are missing, not stated or not interpretable have been excluded from the denominator.
A birth is defined as the event in which a baby comes out of the uterus after a pregnancy of at least 20 weeks gestation or weighing 400 grams or more.
Births included are vaginal births, including non-instrumental and instrumental births. A non-instrumental vaginal birth is one in which the baby is born through the vagina without the assistance of instruments. An instrumental birth is a procedure that uses instruments (forceps or vacuum extraction) to assist the baby to come out through the vagina.
Births excluded are caesarean sections. Postpartum perineal status is defined as: 1st degree laceration/vaginal graze (Code 2)—Graze, laceration, rupture or tear of the perineal skin during delivery that may be considered to be slight or that involves one or more of the following structures:
2nd degree laceration (Code 3)—Perineal laceration, rupture or tear as in Code 2 occurring during delivery, also involving:
3rd degree laceration (Code 4)—Perineal laceration, rupture or tear as in Code 3 occurring during delivery, also involving:
Excludes laceration involving the anal or rectal mucosa.
4th degree laceration (Code 7)—Perineal laceration, rupture or tear as in Code 4 occurring during delivery, also involving:
