RESUMEN

BACKGROUND: The Japanese government recently announced the 'Five-Year Plan for Promotion of Measures Against Dementia (Orange Plan)' to promote people with dementia living in their communities. To achieve this, it is imperative that patients hospitalized with behavioural and psychological symptoms of dementia (BPSD) are helped to return to their own homes. The aim of the present study was to identify predictors of home discharge among patients hospitalized for BPSD. METHODS: A single-centre chart review study was conducted on consecutive patients hospitalized from home between April 2006 and March 2011 for the treatment of BPSD. The frequency of discharge back to home was examined in relation to a patient's active behavioural problems and demographics at the time of admission. Diagnoses of dementia were made on the basis of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, and consensus guidelines for the clinical and pathologic diagnosis of dementia with Lewy bodies. RESULTS: In all, 391 patients were enrolled in the study. Of these patients, 163 (42%) returned home. Multiple logistic regression analysis identified high Mini-Mental State Examination and Nishimura-style senile activities of daily living scores as significant independent predictors of home discharge. In contrast, living alone and manifestation of aggressiveness at the time of admission were negatively associated with home discharge. CONCLUSIONS: Few patients hospitalized for BPSD are discharged home, and this number is affected by a patient's clinical and demographic characteristics at the time of admission. These findings should be considered in designing and implementing optimal management and care strategies for patients with BPSD.

RESUMEN

OBJECTIVE: Most community-based studies have shown a more malignant clinical course for patients with dementia with Lewy bodies (DLB) than Alzheimer's disease (AD). We examined differences in outcomes between patients with DLB and AD hospitalized for the treatment of behavioral and psychological symptoms of dementia. METHOD: A chart review was conducted of patients with either AD or DLB hospitalized in the acute psychogeriatric ward between January 2008 and December 2011 in Kahoku-City, Ishikawa, Japan. Outcome measures were discharge destinations and time to death. A diagnosis of AD was made according to DSM-5 criteria, whereas a diagnosis of DLB was made according to the Consortium on DLB International Workshop criteria for probable DLB. Pharmacologic treatment was optimized under constant monitoring of patients. Cholinesterase inhibitors and yi-gan san were tried prior to antipsychotics in DLB patients. RESULTS: The study cohort consisted of 224 patients with AD and 106 with DLB. After matching for sociodemographic factors and cognitive and physical function, it was found that antipsychotics were less frequently used during hospitalization in patients with DLB than AD (63% vs 82%, respectively, P < .01), whereas cholinesterase inhibitors (88% vs 43%, P < .001) and yi-gan san (35% vs 20%, P < .05) were more frequently used in patients with DLB. There were no significant differences in discharge destinations between the 2 groups. The 5-year cumulative survival rates were similar in the AD and DLB groups (46.4% vs 45.7%, respectively, P = .6225). CONCLUSIONS: Optimization of pharmacologic treatment during hospitalization could reduce the use of antipsychotics and improve the subsequent clinical course in DLB.

RESUMEN

In recent years, it has been noticed that adolescent and adult patients with autism spectrum disorder (ASD) sometimes visit psychiatric medical institutions. In some cases, these patients commit an act of violence and are dealt with by psychiatric emergency and forensic psychiatric services. In this report, we present two cases with ASD who visited a psychiatric emergency service because of the 'time slip' phenomenon, and discuss the clinical significance of this phenomenon.
