Impact of intervention on secondary outcomes
Resident’s mean ACB scale decreased from 1.21 at baseline to 0.94 at endpoint in the intervention group, and from 1.21 at baseline to 1.14 at endpoint in the control group. Similarly, models estimating resident’s ACB scale showed a lowered risk of ACB scale with a rate ratio of 0.800 (95% CI: 0.678-0.0944) in the intervention group when compared to the control group over the period of the study. Residents in the intervention group had lower odd of taking one or more benzodiazepines or antipsychotics (odds ratio 0.68, 95% CI 0.439–1.042) over the study period but was not statistically significant (
