nKPI - summary over time

There have been changes over time to the specifications of the indicators that make up the national Key Performance Indicators (nKPI) collection. As such, trends for some measures cannot be calculated or should be interpreted with caution (Table 1). For information on interpreting changes over time for the national Key Performance Indicators (nKPI) collection, including as a result of changes to indicator specifications and other factors, see Technical notes and Impact of COVID-19.

Table 2 presents trends for selected measures. Trends are calculated as a linear trend across all available data points. Data points for December periods are not shown in the table but are available in the Data tables accompanying this report. Of the 27 measures presented (noting some of the 22 indicators have, or are split into, more than one part), 11 have improved, 2 have had no (or limited) change, 6 have not improved, and trends for 8 cannot be calculated.

Table 1: Selected measures: key changes to indicator specifications

Measure Summary of change to indicator specification(a) Impact of change to indicator specification

PI13: First antenatal visit before 14 weeks

Change to antenatal visit timing

Data from June 2021 on cannot be compared with previous periods

PI01: Birthweight recorded

Change to definition of in-scope babies

Data can be compared between periods with caution

PI02: Low birthweight

Change to definition of in-scope babies, inclusion of multiple births

Data can be compared between periods with caution

PI11: Smoking during pregnancy—current smoker

Age range expanded, change to time period for inclusion of smoking status results

Data from June 2021 on cannot be compared with previous periods for ages less than 20 or the total. Data for ages 20 and over can be compared with caution.

PI03: Indigenous health assessment—aged 0–14

Age range and included MBS items expanded

Data from December 2021 on cannot be compared with previous period for ages 5–14 or the total. Ages 0–4 can be compared with caution.

  1. Unlike in previous periods, reporting to the nKPI collection for June 2020, December 2020 and June 2021 was made voluntary in acknowledgement of the additional pressures on organisations because of COVID-19.
  2. There have been changes to the specification of this indicator over time. See Table 1 and Technical notes for more information.

Notes:

  1. Key: ✔ = improved; ✘ = not improved; ≈ = little or no change.
  2. Trend is calculated as a linear trend between the June 2017 and June 2021 reporting periods, including the December reporting periods. December data points are not shown in this table but are available in the Data tables accompanying this report.
