A randomized trial of dementia care in nursing homes

OBJECTIVE: To evaluate the efficacy of a dementia care program to reduce behavior disorders in nursing home patients with dementia.

The General Medical Health Rating: A Bedside Global Rating of Medical Comorbidity in Patients with Dementia

OBJECTIVE: Dementia is a serious public health problem. General medical comorbidity is common in dementia patients and critical to their care. However, little is known about medical comorbidity in these patients, and there are no straightforward bedside global rating scales for the seriousness of comorbid medical illness. This paper describes the development and measurement properties of the General Medical Health Rating (GHMR), a rapid global rating scale of medical comorbidity in dementia patients.

Accuracy of clinical diagnosis of Alzheimer disease and clinical features of patients with non-Alzheimer disease neuropathology.

Summary:Neuropathological examination confirmed the clinical diagnosis of possible or probable Alzheimer disease (AD) in 90 of the first 100 patients who came to autopsy at the Johns Hopkins Alzheimers Disease Research Center. In 10 cases, postmortem brain examination did not confirm AD but revealed variable patterns of neuronal loss in neocortex and limbic structures without amyloid deposits. The most common pattern of degeneration was relatively isolated hippocampal sclerosis (HS). Despite the finding that the 10 patients with non-AD neuropathology were ill for less time and were less cognitively impaired at study entry than those patients with definite AD, they had shorter survival times and showed equal behavioral disturbance at study entry (on a standardized measure). The clinical case reports included here suggest early and progressive prominent behavioral disturbance and other indexes of rapid illness progression in three of the four HS patients and two other non-AD patients. We conclude that the criteria of the National Institute of Neurological Disorders and Stroke/Alzheimer Disease and Related Disorders Association for possible or probable AD are highly accurate and that misdiagnosis is most likely to occur early in the course of illness and in patients with prominent behavioral disturbance or other atypical features

Psychiatric Diagnosis and Uncooperative Behavior in Nursing Homes

The prevalence of psychiatric disorders and behavioral disturbances in nursing homes is high, but the relationship between the two is unknown. We studied 454 new admissions who were diagnosed by research psychiatrists using DSM-III-R criteria and compared patients who nursing staff designated as cooperative or uncooperative by psychiatric diagnosis and use of restraints and neuroleptics. Uncooperative patients (n = 79; 17.4%) had a variety of psychiatric disorders (total, 87.3%) but particularly had dementia syndromes complicated by delusions, depression, or delirium (44.3%). Uncooperative patients were more frequently restrained and prescribed neuroleptics. Determining the origins of behavior disorders in patients with psychiatric disorders in nursing homes may reduce behavior disturbances. (J Geriatr Psychiatry Neurol 1992;5:102–105).

Adjustment to residential placement in Alzheimer disease patients: does premorbid personality matter?

Aim. To evaluate the influence of premorbid personality on adaptation to placement in a long‐term care facility.

Falls and age in patients with Alzheimer's disease.

The studys objective was to estimate the prevalence of falls in community-residing patients with Alzheimers disease (AD) and to investigate the relationship between falls and age in AD. This was a study of 326 community-residing patients with AD according to National Institute of Neurological and Communicative Disorders and Stroke and Alzheimers Disease and Related Disorders Association criteria. The patients and their caregivers were asked about falls, behavioral disturbances, and medication use within the last 2 weeks. The patients were also rated on standardized measures of cognitive impairment, stage of dementia, depression, daily activities, general health, and extrapyramidal symptoms. Falls occurred in 24 (7.4%) patients with AD during the last 2 weeks. Using multiple logistic regression analyses, falls were independently associated with old age (odds ratio = 1.2; p = .03; 95% confidence interval = 1.0 to 1.4) but not with other variables examined. The authors conclude that falls in community-residing patients with AD are significantly associated with old age. Population-based prospective studies are needed to investigate further the risk factors for falls in AD.

Predictors of mortality in dementia patients upon entry into long-term care

Background. The purpose of this study was to develop an algorithm that predicts survival in patients with dementia upon entry into long-term care. There are, as yet, no predictive equations developed for those in the late stages of Alzheimer’s disease (AD). Methods. This was a prospective, observational study of 132 patients with dementia (61% with AD) followed for up to 5.0 years (median of 41.0 months) after admission to a long-term care facility for dementia patients. Information on demographic characteristics, physical health, and cognitive, emotional, and behavioral characteristics was collected shortly after admission and entered as predictors of time until death in Cox regressions. Findings were used to derive an index predicting mortality. Results. There were 60 deaths among the 132 patients (45.4% mortality), with an average survival of 22.4 months in those who died. Better physical health and the presence of delusions were associated with longer survival. These two variables were aggregated into the Copper Ridge Index (CRI). Each one-point increase on the CRI was associated with a four-fold greater likelihood of death over 5 years.
