Person-centered, non-pharmacological intervention in reducing psychotropic medication use among residents with dementia in Australian rural aged care homes

Abstract

BackgroundHigh rates of psychotropic medications are prescribed in aged care homes despite their limited effectiveness and associated adverse effects. We aim to evaluate the changes in prescription patterns for elderly residents with advanced dementia in the ‘Harmony in the Bush Dementia Study’. Harmony in the Bush is a person-centered model of dementia care in nursing homes, based on the principles of Progressively Lowered Stress Threshold (PLST) and person-centered music intervention.MethodsOur larger study was a quasi-experimental design conducted in five rural nursing homes in Queensland and South Australia. Medication charts (n = 31) were collected retrospectively from three Australian rural aged care facilities through contacting the facility managers before the intervention and after 6 months. Fifty-three staff participated in 31 semi-structured interviews and 8 focus group at post-intervention, and at 1-month and 3-months follow up.ResultsThe median age of the participants was 83 years, and 68% of them were female. Polypharmacy was measured in 87% of the participants. Hypertension, hyperlipidemia, diabetes, and the Alzheimer’s disease were the major comorbidities identified in residents. None of the residents received more than the maximum dose of psychotropic medications recommended by the guidelines. There was a reduction of 22.4% in the use of at least any psychotropic medication, 19.6% reduction in antipsychotics and benzodiazepines, and 6.5% reduction in antidementia medicines prescription from baseline to at post-intervention, however, these were not statistically significant. There was a decreasing trend in the use of inappropriate use of medications. Psychotropic medications were prescribed up to 43% and antidementia in 45% of participants for more than 6 months. Major themes extracted from qualitative data were reduced/decreased/cessation of medication use, introducing a rest period and the music intervention combined was an alternative approach for medications use, and less behaviors, and ultimately the less use of medications.ConclusionsOur findings indicate that the Harmony in the Bush model as a non-pharmacological approach reduces the prescription of psychotropic medications and inappropriate medications in rural nursing homes as supported by findings from both quantitative and qualitative data.Trial registration: ANZCTR, ACTRN12618000263291.
