Adult Admitted Patient Survey

In 2023, BHI introduced a new statistical approach to improve fairness and precision when flagging hospital performance as significantly higher (green) or significantly lower (red) than the NSW result in the Snapshot report and supplementary data tables. The report and supplementary data tables on this page use a previous methodology for identifying significant difference which is no longer in use.

When looking at performance over time, the focus should be on the changes in percentage results rather than whether those results are flagged as green or red, noting that year-on-year differences may not reflect clinically or statistically significant differences and that changes in a hospital’s patient mix may contribute to changes in results.
