The influence of caregivers and behavioral and psychological symptoms on nursing home placement of persons with Alzheimer's disease: A matched case-control study.

OBJECTIVES: Behavioral and psychological symptoms of dementia in individuals with Alzheimer's disease and caregiver characteristics may influence the decision to provide care at home or in a nursing home, though few studies examine this association near the actual time of nursing home placement. Using a matched case-control design, this study investigates the association between (1) total Neuropsychiatric Inventory score, (2) the Neuropsychiatric Inventory-4 (an agitation/aggression subscale), and (3) individual domains of the Neuropsychiatric Inventory and nursing home placement. METHODS: Data from the South Carolina Alzheimer's disease Registry provides an opportunity to expand the literature by looking at cases at the time of nursing home care eligibility/placement and allowing for propensity-score-matched controls. Cases (n = 352) entered a nursing home within 6 months of study initiation; controls (n = 289) remained in the community. Registry data were combined with caregiver survey data, including the Neuropsychiatric Inventory. Conditional logistic regression was applied. RESULTS: A 10% increase in the Neuropsychiatric Inventory score implied a 30% increase in odds of nursing home admission (odds ratio: 1.30; 95% confidence interval: 1.14-1.50), having married or male caregivers predicted nursing home placement. Cases versus controls were significantly more likely to have behavioral and psychological symptoms of dementia related to agitation/aggression 1 month prior to nursing home admission. CONCLUSION: Interventions targeting behavioral and psychological symptoms of dementia without available effective interventions in individuals with Alzheimer's disease and caregiver support services are necessary to prevent or delay nursing home admission.

Impact of a medication management system on nursing home admission rate in a community-dwelling nursing home-eligible Medicaid population.

BACKGROUND: Community-dwelling frail elderly have an increased need for effective medication management to reside in their homes and delay or avoid admission to nursing homes. OBJECTIVE: The objective of this study was to examine the impact of a medication management system on nursing home admission within the community-dwelling frail elderly. METHODS: This prospective cohort study compared nursing home admission rates in intervention and control clients of a state Medicaid home and community-based waiver program. Groups were matched on age (±5 years), race, gender, and waiver program start date (±120 days). The medication management service consisted of 2 parts: 1) prescription medicines dispensed from the client's local pharmacy in a calendar card, and 2) a coordinating service by a health educator to address medication-related problems as they arose. The primary dependent variable was admission to a nursing home. RESULTS: A total of 273 clients agreed to participate, enrolled, and had at least 1 prescription dispensed. The matched control group was composed of 800 other clients. The client sample was 72 years of age, 73% (785/1073) non-white, 75% (804/1073) female, and enrolled in the waiver program approximately 50 months. The 2 groups were similar on all demographic variables examined. Six clients (2.2%) in the intervention group and 40 clients (5.0%) in the control group were admitted to a nursing home at least once during the study period. Logistic regression was used to test the model predicting at least 1 nursing home admission. Control group clients were 2.94 times more likely to be admitted to a nursing home than clients in the intervention group. CONCLUSIONS: The medication management service implemented within this study was effective in reducing nursing home admissions in a group of frail community-dwelling elderly.

Person-centered planning training for consumer-directed care for the elderly and disabled.

Based on the need for a training program for person-centered planning SC Choice, a Real Choice/Independent Living Grant, included the development of training materials and a training program for the implementation of the transformation from agency case manager to care advisor. The development of this training included receiving the person-centered planning training currently used by the developmentally disabled agencies, as well as interviews and focus groups with interested staff and participants. A training program for the Elderly/Disabled Waiver population using adult learning techniques is described in detail Included in this training are the philosophy, the activities, and the necessary steps to complete person-centered planning for the transition of a case manager to a care advisor in a consumer-directed program for the elderly.

Application of capture-recapture methodology to estimate the prevalence of dementia in South Carolina.

PURPOSE: The purpose of this study was to estimate the prevalence of dementia in individuals 65 years of age and older in the state of South Carolina using capture-recapture methodology. METHODS: We linked data from the Department of Mental Health admissions, inpatient admissions, and emergency room visits. Separate log-linear models were used to obtain estimates of the underascertainment-corrected prevalence of dementia in twelve age-gender-race subgroups, which were summed to estimate the prevalence of dementia in the total population. RESULTS: We found an overall prevalence of dementia of 14% in South Carolina for persons 65 years of age and older using capture-recapture methodology. This estimate of persons with dementia is 25% higher than the identified cases of dementia in the South Carolina Alzheimer's Disease Registry (10.5%). CONCLUSIONS: Although capture-recapture methods are prone to limitations, they can be used to more accurately estimate the prevalence of dementia in a geographic area.

Co-morbidity associated with dementia.

PURPOSE: The purpose of this study was to identify common co-morbid conditions associated with dementia subtypes and to evaluate the association of hypertension, diabetes mellitus, atrial fibrillation, congestive heart failure, and anemia with dementia subtypes relative to controls. METHODS: Hospital discharge data were used to identify 15,013 subjects from South Carolina with a diagnosis of dementia between 1998 and 1999. A control group of 15,013 persons without dementia was randomly sampled from hospital discharge records and matched to persons with dementia on the basis of age, race, and gender. Multiple hospitalizations for each patient were merged, and repeated diagnoses during separate hospitalizations were counted once. RESULTS: After adjusting for age, race, and gender, persons with Alzheimer's disease and dementia associated with medical conditions were less likely to be diagnosed with hypertension, diabetes, congestive heart failure, and atrial fibrillation than were controls. Patients with multi-infarct dementia were also less likely to have congestive heart failure, but were more likely to have diabetes. Anemia was not associated with any dementia subtype. CONCLUSIONS: There are distinct differences in comorbid conditions among dementia subtypes. Our research does not support previous studies that suggest a circulatory component to the development of Alzheimer's disease.
