Short name: | AHPF PI 2.1.2–Females with an antenatal visit in the first trimester of pregnancy, 2020 |
Synonymous names: | Proportion of women who gave birth and had at least one antenatal visit in the first trimester; Pregnancies with an antenatal visit in the first trimester |
METEOR identifier: | 728325 |
Registration status: | Health, Standard 01/12/2020 |
Description: | Number of females who gave birth, where an antenatal visit was reported in the first trimester, as a proportion of all females who gave birth. |
Rationale: | The primary care needs of all Australians are met effectively through timely and quality care in the community. Good antenatal care is associated with positive health outcomes for mothers and babies. |

Computation description: | First trimester is defined as up to and including 13 weeks of pregnancy. Excludes women whose gestation at first antenatal visit was not stated. Analysis by state/territory, remoteness, Socio-Economic Indexes for Areas (SEIFA) Index of Relative Socio-Economic Disadvantage (IRSD) and Primary Health Network (PHN) is based on the usual residence of the mother. Data excludes Australian non-residents, residents of external territories and records where state/territory of residence was not stated. Age-standardised rates are calculated for Indigenous and non-Indigenous Australians. Presented as a:

Computation: | Crude percentage: 100 x (Numerator ÷ Denominator) Age-standardised percentage: calculated using the direct method, using five-year age groups from 15–19 to 40–44 with the 30 June 2001 Australian female estimated resident population (ERP) based on the 2001 Census as the standard population. Age-standardisation should be done in accordance with the National Indigenous Reform Agreement Performance Information Management Group (NIRAPIMG) agreed principles for direct age-standardisation (see Comments section. Note that Principle 4 is not applicable for this indicator). |
Numerator: | Number of females who gave birth to at least 1 live or stillborn baby, where an antenatal visit was reported in the first trimester (up to and including 13 completed weeks. |

Denominator: | Total number of females who gave birth to at least 1 live or stillborn baby (where gestation at first antenatal visit is known). |

Comments: | Most recent data available for 2020 Australian Health Performance Framework reporting: 2018 (calendar year data). Information is included in the National Perinatal Data Collection (NPDC) for both live births and stillbirths, where gestational age is at least 20 weeks or birthweight is at least 400 grams, except in Victoria and Western Australia, where births are included if gestational age is at least 20 weeks or, if gestation is unknown, birthweight is at least 400 grams. Antenatal visits relate to care provided by skilled birth attendants for reasons related to pregnancy. For the Australian Capital Territory, first antenatal visit is often the first hospital antenatal clinic visit. In many cases earlier antenatal care provided by the woman’s GP is not reported. NIRAPIMG agreed Principles for reporting directly age-standardised rates for administrative data. Note that Principle 4 is not applicable for this indicator. Overarching principle: Before undertaking age-standardisation, analysts must investigate the data being used to understand the age-specific distribution and any limitations that may impact on the results. Principle 1: The standard population used should be the Australian estimated resident population as at 30 June 2001 (for this indicator, females aged 15–44) based on the 2001 Census. Principle 2: If the denominator is less than 30 in any one age group, then do not attempt to produce age-standardised rates. Age groups may be collapsed to obtain a denominator of 30 or more (provided that this is in accordance with Principle 3). Principle 3: If the total number of Indigenous events (for example, deaths, hospital separations) is less than 20, then do not attempt to produce age-standardised rates. Combining several years of data, or aggregating jurisdictions should be considered to obtain a total of 20 or more events. If this does not meet the purpose (that is, data are required for time series or jurisdictional comparisons), or does not result in a total of 20 or more events, then other measures and contextual information should be reported instead of age-standardised rates which could include total number of events, crude rates, age-specific rates, age-specific rate ratios and median age at death. Principle 4: Not applicable. Principle 5: Additional contextual information (most importantly age-specific rates and ratios) should be provided in addition to age-standardised rates when:
Principle 6: For conditions restricted to a specific age group (for example, conditions originating in the perinatal period and sudden infant death syndrome (SIDS)), it is recommended to report the age-specific rate for the age group of interest instead of the age-standardised rate. The term ‘Aboriginal and Torres Strait Islander people’ is preferred when referring to the separate Indigenous peoples of Australia. However, the term ‘Indigenous’ is used interchangeably with ‘Aboriginal and Torres Strait Islander’ in this indicator to assist readability. |
