Implementation of DIAMOND-Lewy Guidelines for Emergency Department Antipsychotic Use in Older Patients With Cognitive and Movement Disorders

The goal of this observational study is to learn about current practices for the acute neuropsychiatric management of older adults during emergency department (ED) visits. Researchers will compare current standard of care practices with implemented guideline practice to see if standardized medication guidelines help reduce the usage of antipsychotics and/or benzodiazepines during acute presentations. The main questions this study aims to answer are: * How many older adults are receiving antipsychotics or benzodiazepines during emergency department visits? * Why are older adults receiving antipsychotics or benzodiazepines during emergency department visits? * How many older adults who receive antipsychotics or benzodiazepines during emergency department visits have an underlying cognitive or movement disorder? * What effects does administration of antipsychotics or benzodiazepines during emergency department visits have on patient outcomes in older adults and adults with neurocognitive disorders? * Does implementation of standardized medication guidelines help reduce the usage of antipsychotics and/or benzodiazepines during acute presentations?
