Abstract
BackgroundThere is limited best- practice evidence to address behavioral and psychiatric symptoms for those with advanced dementia in Australian rural nursing homes. This study aims to evaluate the outcomes of a person-centered, non-pharmacological dementia care model, ‘Harmony in the Bush’, based on the Progressively Lowered Stress Threshold principles and person-centered music in rural Australia.MethodsA quasi-experimental study was conducted in five rural nursing homes in Queensland and South Australia. Seventy-four residents with advanced dementia participated in this intervention study, which yielded a sample power of 80%. Eighty-seven staff completed the Caregiver Stress Inventory at pre-post four-weeks of intervention. Staff training workshops focusing on the theory and delivery of the Progressively Lowered Stress Threshold principles and a music intervention. We used reported changes in agitation of the residents, measured using Cohen- Mansfield Agitation Inventory, and staff’s caregiving stress, using Caregivers Stress Inventory. Triangulation using post- intervention qualitative evaluation from 13 focus group discussion and 38 staff interviews. This study adheres to the CONSORT guidelines.ResultsMean age of residents with advanced dementia was 82.4 (7.7) years and 69% were females. The mean age of admission was 80.1(8.4) years. Baseline measures indicated that 32.7% had mild- severe pain and 30.5% reported mild-severe sadness. The results showed statistically significant decline in aggressive behaviors, physically non-aggressive behaviors, verbally agitated behavior and hiding and hoarding. There was comparable reduction in staff stress in the domains of aggressive behaviors, inappropriate behaviors, resident safety, and resource deficiency.ConclusionsThe Harmony in the Bush model is effective in reducing behavioral and psychiatric symptoms in advanced dementia with significant reduction in staff stress levels in nursing homes in rural Australia.Trial Registration: Australian and New Zealand Clinical Trials Registry (ANZCTR) on 20/2/2018 (Registration No: ACTRN12618000263291p). https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=374458
