dementia
Fifteen RACFs enrolled and participated in the study. After randomisation, 7 RACFs (560 residents) were allocated to the intervention arm and 8 RACFs (737 residents) were allocated to the control arm. Twenty-two residents were lost to follow-up and 16 residents were excluded because they were under 65 years of age, where the Beers® Criteria are not applicable. Overall, 1275 residents from the baseline and 1301 residents from the endpoint were included in the final analysis. The flow diagram of the study population is presented in Fig. Study participants flowchart.The baseline characteristics of participating residents were similar between groups, although the control group had slightly more females and had higher percentage of residents diagnosed with dementia (Table Baseline characteristics of study participants (RACF residents).PIMs = Potentially Inappropriate Medications, * PIMs categories ≥ 1 are inclusive categories (i.e., ≥ 1 PIMs includes data shown in ≥ 2 PIMs and ≥ 3 PIMs and thus % values do not sum to 100%).Comparison between PiRACF study sample characteristics (at baseline) and national data.*Residents under 65 years were excluded from the national data.
