About this report
These full data reports of the Australasian Clinical Indicator Report list collective performance
against each of the ACHS clinical indicators that were collected during 2011.
In this report, each of the indicators from the Medication Safety CI set has a table (shaded green)
that describes the indicator, its intent, numerator and denominator. Tables summarise the data
submitted in every year since 2004 that the indicator has been available.
For indicators of interest, this report will assist in better understanding the true granularity of the
data.
For indicators launched before 2009, trends in the rates over time are reported and the data are
displayed using a line graph. More than three years of data are needed to display a trend.
Outlier information is displayed using funnel plots.
Three measures of variation in rates between healthcare organisations (HCOs) are included; these
are quantified by the differences between the 20 th and 80 th centiles.
These green tables also include statistical estimates of the potential gains for all eligible indicators,
if changes in the distribution of data were achieved.
Centile gains show the number of units (for many CIs, patients) that would benefit if the
overall level of performance achieved by all organisations combined was the same as that of
the better performing 20% of organisations (as defined by the 20th or 80th centile rate).
Stratum gains show the number of units (for many CIs, patients) that would benefit if the
performance of organisations outside the better performing stratum was lifted to that level.
Strata can only be considered for these comparisons when there is sufficient data (at least
five organisations contributing to each stratum). Stratum differences may represent the
contrast between either metropolitan or non-metropolitan organisations, between any single
state / territory and the others, or between organisations belonging to the public and private
sectors. Where the differences between strata are statistically significant, further information
is provided within the report, and can be identified by the presence of a table shaded mauve
(public / private), pink (metro / non-metro) or apricot (states / territories / NZ). Multiple tables
are displayed when more than one stratum is statistically significant. Only the largest stratum
gain is recorded in the opening green table.
Outlier gains show the number of units (for many CIs, patients) that would benefit if those
organisations with results that are more than three standard deviations poorer than average
could achieve the average level of performance.
