Babies born in the Whanganui DHB, New Zealand

Deprivation is derived according to the residence of the individual. Numbers and rates are presented by deprivation quintile, ranging from quintile 1 (least deprived) to quintile 5 (most deprived). Deprivation scores are based on the 2006 New Zealand Deprivation Index for people giving birth before 2010, on the 2013 Deprivation Index for people giving birth from 2010 to 2015 and on the 2018 Deprivation Index from 2016 onwards.

Each individual represented in the data is allocated to a single ethnic group, using the following priority system: Māori > Pacific peoples > Indian > Asian (excl. Indian) > Other > European. Individuals of European and of Other ethnicities are often grouped together and presented as being part of the 'European or Other' ethnic group due to small numbers in the ''Other' ethnic group.

The numbers only include live-born babies at any gestation. Babies resulting from a twin or multiple pregnancy are counted individually.
Each year, a small proportion of births are recorded in MAT without a birth status. These records are notably less complete than records for live births and are not included. The majority of these records are reported as planned homebirths but can also include unplanned homebirths and out-of-hospital births. From 2012 to 2021, the proportion of records where birth status was not reported ranged from 0.4 to 1.3% of total births in any given year. Te Whatu Ora is currently confirming information about these births. Where possible, records will be updated, and these changes will be reflected in future updates.

From 1 July 2019, diagnoses codes are assigned using the 11th Edition of ICD-10-AM (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification) and procedure codes are assigned using the 11th Edition of ACHI (Australian Classification of Health Interventions) (Source: The Independent Health and Aged Care Pricing Authority).
Some maternity events (people giving birth in hospital and live babies born in hospital) are impacted by changes in the 11th Edition clinical coding standards, particularly place of birth and type of birth data. Therefore, this data may show variation due to the change in coding standards rather than a true increase.
The Primary Maternity Services Notice 2021 came into force on 29th November 2021, introducing changes to the terms and conditions on which maternity providers can claim for providing primary maternity services. This revokes the Primary Maternity Services Notice which came into effect on 1 July 2007 and its amendments.
There are underlying changes to the way some data are now captured (such as smoking status or breastfeeding and Well child referral). Also some metrics are no longer collected (such as height and weight at registration, which impacts on BMI calculation). It is important to consider these changes when comparing claims data pre and post November 2021.
