Randomisation and recruitment
Randomisation was performed at the facility level. RACFs were stratified by size of facility and randomised into either the intervention or control group through computer-generated allocation by an independent person external to the research team. All RACFs in the ACT, Australia, that met the inclusion criteria were invited to participate in this study. Due to the nature of the intervention, participants were not blinded. Permanent residents of participating RACFs were included unless they requested to opt out. New residents entering RACFs after the baseline data collection that remained at the RACFs until the end-point data collection, were also included. Respite (non-permanent) residents were excluded. Only residents who were aged 65 years or over were included in the data analysis.
