Evidence and sources
Every empirical claim in this section is tied to a named source. This is the full list of 45 trials, systematic reviews, guidelines and Australian regulatory documents, with the topic pages that rely on each one.
How these sources are used
Interventions are graded on randomised trial evidence for the outcome that matters: symptoms, function, quality of life, hospital admission or survival. Trials in residential care are preferred. Where the only evidence comes from hospitals, from people living at home or from studies that were not randomised, that is stated where the finding is described.
Observational studies, cross-sectional surveys and single-arm programs are labelled as such. Much of what is known about how medicines are used in Australian aged care comes from observational data, and it is presented that way.
Australian regulatory details, quality indicator definitions, PBS arrangements and pharmacy program rules are correct as at the review date below and change. Confirm current arrangements against the primary source before relying on them.
Last full evidence review: October 2026.

Listing a source is not an endorsement of every conclusion its authors draw, and summarising a trial in one sentence necessarily loses detail. Where a finding matters to a decision, read the original.
