Most earlier research on decreasing prescribing in dementia care consisted of small trials or observational analyses, with restricted proof from large-scale randomized research.
The outcomes have been placing. “Folks with dementia residing in nursing properties and in the neighborhood have been prescribed much less and we didn’t detect unfavorable well being impacts for these teams,” mentioned Michelle Harnisch, analysis pupil on the London College of Economics and first creator of the research.
The findings are necessary as a result of antipsychotics, equivalent to quetiapine, are sometimes utilized in dementia care to handle behavioral signs.
