| 1 | Singleton | 2 | Twins | 3 | Triplets | 4 | Quadruplets | 5 | Quintuplets | 6 | Sextuplets | 8 | Other | 9 | Not stated |
| DSS specific information: National Minimum Data Set (NMDS) Perinatal: Multiple pregnancy increases the risk of complications during pregnancy, labour and delivery and is associated with higher risk of perinatal morbidity and mortality. Plurality of pregnancy is determined by the number of babies that are in scope for the Perinatal NMDS (i.e. births of at least 20 weeks gestation or at least 400g birth weight). In the case of multiple pregnancies, if one or more fetuses were removed from the uterus before 20 weeks gestation, for example, by abortion (spontaneous, induced or fetal reduction) they are not considered in determining the birth plurality. For example, in a twin pregnancy, where one twin is aborted before 20 weeks gestation and the remaining twin is born and is in scope for the Perinatal NMDS, plurality is coded as ‘1 Singleton’. If both twins are born at 20 weeks gestation or more, plurality is coded as ‘2 Twins’. This item is collected for the mother only. |

| DSS specific information: Birth order is only assigned to births that are in scope for the Perinatal NMDS (i.e. births of at least 20 weeks gestation or 400g birth weight). In the case of multiple pregnancies, if one or more fetuses were removed from the uterus before 20 weeks gestation, for example, by abortion (spontaneous, induced or fetal reduction), they are not considered in the assignment of birth order for any remaining fetuses that are born. For example, in a twin pregnancy, where one fetus is aborted before 20 weeks, no birth order would be recorded for that twin. If the remaining twin is born and is in scope for the Perinatal NMDS, then their birth order would be recorded as ‘1 Singleton or first of a multiple birth’. If both twins are born and are in scope for the Perinatal NMDS, the first twin will be assigned a birth order of ‘1 Singleton or first of a multiple birth’ and the second twin will be assigned a birth order of ‘2 Second of a multiple birth’. In the case of multiple births, this item should be recorded for each baby born. |
