BRUCE
Consent to participate in the study was gained at the facility level, rather than the resident level, given the impracticalities of gaining informed consent from a large sample of individual residents, many of whom are likely to have cognitive impairment; there was a low risk to participants and actions were taken to protect participant privacy. Residents were able to opt out of having their data included in the study, and the process on how to do this was provided to residents and families. The trial was approved by Human Research Ethics Committees at the University of Canberra (HERC:2007), ACT Health (2019/ETH13453) and Calvary Public Hospital Bruce (30-2019).The trial was registered with the Australian New Zealand Clinical Trials Registry (ANZCTR) (ACTRN: ACTRN12620000430932 on 01/04/2020). All experiments were performed in accordance with relevant guidelines and regulations. Findings are reported in accordance with the extension of the Consolidated Standards of Reporting Trials (CONSORT) statement to cluster randomised controlled trials
