The Influence of a Specialized Dementia Ward on the Treatment of Alzheimer's Disease Patients.

Abstract

Background: Hospitalization for severe neuropsychiatric symptoms in Alzheimer's disease (AD) presents challenges, often requiring environments that ensure safety while addressing therapeutic needs. Traditional closed wards, originally designed for psychiatric conditions like schizophrenia, may not fully address the unique needs of AD patients. This study evaluates the effectiveness of a Specialized Dementia Ward (SDW) tailored for AD patients compared to a General Ward (GW). Methods: A retrospective study compared 51 AD patients in an SDW (February 2018-January 2019) and 40 AD patients in a GW (December 2017-January 2018). Patients met NINCDS-ADRDA criteria, with a Clinical Dementia Rating (CDR) ≤ 2 and a Korean Mini-Mental State Examination (K-MMSE) ≤ 20. Clinical assessments at admission and four weeks included K-MMSE, Resident Assessment Instrument Minimum Data Set Version 2.0 (RAI-MDS), and Neuropsychiatric Inventory Questionnaire (NPI-Q). Psychotropic medication use, length of stay, and discharge destination were also analyzed. Results: No statistically significant differences emerged between SDW and GW groups regarding baseline demographics, cognitive function, ADL, or neuropsychiatric symptoms. At four weeks, both groups exhibited trends toward improved K-MMSE, RAI-MDS, and NPI-Q scores and reduced psychotropic usage, but these did not reach statistical significance. Although mean length of stay was shorter for SDW patients (3.2 vs. 4.9 months; p = 0.078), the difference was not significant. Notably, a significantly higher proportion of SDW patients were discharged home (58.8% vs. 37.5%; p = 0.049). Conclusions: Although clinical outcomes were comparable, the SDW demonstrated advantages in facilitating discharge to home, suggesting that tailored ward environments may better support AD patients. These findings underscore the importance of therapeutic environments in dementia care and highlight the need for further research on specialized dementia ward designs to improve outcomes and patient satisfaction.
