Objectives: To reveal whether an accessible open floorplan Multisensory Stimulation Environment (MSSE) room design has a positive impact as a nonpharmacologic intervention for episodes of Behavioral and Psychological Symptoms of Dementia (BPSD) in older adults living in a Memory Care Assisted Living (MCAL) facility as well as reducing the need for direct care supervision.
Methods: Retrospective pre/post cohort design of 24 residents living in a Midwest MCAL facility in the United States with a diagnosis of dementia and over 65 years of age, analyzed by secondary medical chart review for 12 months to assess impact of an accessible open floorplan MSSE room design. The pre/post design analyzed secondary data over two periods of time; 6 months prior to the MSSE installation and 6 months following the MSSE installation.
Results: Following the installation of an open floorplan MSSE, the number of observed BPSD episodes changed from 367 (17%) pre-test to 298 (10%) post-test over a 12-month time period. The Comparison of Proportions test determined that the difference in the proportion of BPSD episodes documented was statistically significant with clinical implications.
Conclusions: The accessible open floorplan MSSE room design, located within a single-site MCAL facility, utilized as a nonpharmacological intervention for BPSD, was found in this explorative study to be effective and potentially clinically meaningful in improving behavioral episodes for older adults diagnosed with dementia in MCAL settings
