The etiologic factors of delirium have been frequently studied in hospitalized elderly patients who usually have an underlying disorder, i.e., hip fracture or dementia predisposing to delirium. The etiologic factors of delirium and prognosis in healthy elderly remain unstudied. The aim of our study was to detect the primary and additional etiologic factors contributing to delirium among community-dwelling healthy elderly people without predisposing disorders to delirium and to evaluate 1-year prognosis after discharge to home. ⋯ The plausible etiologic factor of delirium was detected in all cases. Among healthy elderly people, infections and cerebrovascular attacks were the most important etiologic factors for delirium. After discharge to home, 30% of the patients had to be taken into long-term care or had died within 1 year of the delirium.

The objective was to develop a new short-form Geriatric Depression Scale (GDS-12R) suitable for older people living in nursing and residential care settings, including those persons with significant cognitive impairment. A total of 308 newly admitted residents of 30 nursing and residential homes in northwest England were interviewed using the Geriatric Depression Scale (GDS-15), the Mini-Mental State Examination, and the Affect Balance Scale (ABS). ⋯ Furthermore, moderate to high levels of cognitive impairment did not affect the performance of the new version of the scale. The GDS-12R provides researchers and clinicians with a brief, easy-to-administer depression scale that is relevant to residential and nursing home populations.

Previous research on risk of delirium in acute hospital settings identified mainly patient variables (e.g., age) that are not amenable to intervention. The purpose of this study was to develop a model for new delirium in hospitalized older patients that included process of care and social variables. ⋯ Approximately one older patient in five developed delirium after admission to a medical or surgical unit. Risks not easily amenable to intervention included age, cognitive dysfunction, surgery, and intensive care requirements. Risk factors that are potentially modifiable included number of medications and number of procedures. Future research might focus on the efficacy of such intervention to reduce new-onset delirium in acute hospital settings.

Case Reports Randomized Controlled Trial Comparative Study Clinical Trial
Effects of individualized versus classical "relaxation" music on the frequency of agitation in elderly persons with Alzheimer's disease and related disorders.
Confusion and agitation in elderly patients are crucial problems. This study tested Gerdner's mid-range theory of individualized music intervention for agitation. An experimental repeated measures pretest-posttest crossover design compared the immediate and residual effects of individualized music to classical "relaxation" music relative to baseline on the frequency of agitated behaviors in elderly persons with Alzheimer's disease and related disorders (ADRD). ⋯ The Modified Cohen-Mansfield Agitation Inventory measured the dependent variable. A repeated measures analysis of variance with Bonferroni post hoc test showed a significant reduction in agitation during and following individualized music compared to classical music. This study expands science by testing and supporting a theoretically based intervention for agitation in persons with ADRD.

Comparative Study
Some methodological issues in using aggression rating scales in intervention studies among institutionalized elderly.
Aggressive behavior among geriatric psychiatry inpatients spontaneously declines during serial measurements over time with rating scales. ⋯ A "run in" period of at least 4 weeks may be needed in intervention studies using the SOAS to reduce contamination by spontaneous decline.
