Clinical care and unmet needs of individuals with dementia with Lewy bodies and caregivers: an interview study.
Investigators researched the clinical care preferences of individuals living with dementia and caregivers, particularly dementia with Lewy bodies (DLB). Twenty individuals with DLB and 25 caregivers were interviewed via a semistructured questionnaire. The investigators concluded that improving care for individuals with DLB and their families will require a multipronged strategy including education for non-specialist care providers, increasing specialty care access, improved clinical care services, research to support disease prognosis and treatment decisions, and local and national strategies for enhanced caregiver support.

Continuity of nursing care in home health: impact on rehospitalization among older adults with dementia.
The objective of this retrospective cohort study was to examine the association between continuity of nursing care in home health care (HHC) and rehospitalization among persons with dementia (PWD). Multiple years of HHC assessment, administrative, and human resources data from a large urban not-for-profit home health agency was used. Findings showed that wide variations exist in continuity of nursing care to PWD. Consistency in nurse staff when providing HHC visits to PWD is critical for preventing rehospitalizations.

Changes in the agreement between the Minimum Data Set and hospital Medicare claims measures of dementia.
The objective of this study was to examine the agreement between a clinical Minimum Data Set measure of dementia and a diagnosis of dementia documented on a hospital claim across three points in time. A second objective was to examine the extent to which the agreement varied by age, sex, and race/ethnicity. Findings showed that hospital claims for patients aged 66–75 were less likely to be accurate than those for other age groups and suggests that physicians do not always look for signs of dementia in younger adults. Additionally, Asian patients were less likely to have a diagnosis of dementia documented during hospitalization, which could be related to language barriers between patients and clinicians.

Characteristics associated with feeding tube placement: retrospective cohort study of Texas nursing home residents with advanced dementia.
The purpose of this retrospective cohort study was to investigate resident-level, provider-type, nursing home (NH), and regional factors associated with feeding tube (FT) placement in advanced dementia. The investigators concluded that regional, race, and ethnic variations in prevalence of FT use among NH residents suggested opportunities for clinicians and policy makers to improve the quality of end-of-life care by especially considering other palliative care measures for minorities living in border towns.

Biomarker use for dementia with Lewy body diagnosis: survey of US experts.
Researchers investigated clinical practice patterns of dementia with Lewy body (DLB) diagnostic criteria. An anonymous survey was sent to 38 center of excellence investigators inquiring about clinical use of diagnostic tests/biomarkers. They found that neuropsychological testing and MRI remained the most widely used diagnostic tests by DLB specialists. Other tests, particularly, indicative biomarkers, are used only selectively. They recommended research to validate existing potential DLB biomarkers, to develop new biomarkers, and to investigate mechanisms to improve DLB diagnosis.

Dementia caregivers' experiences and reactions to remote activity monitoring system alerts.
Technology-based tools, including remote activity monitoring (RAM) systems, have been proposed as valuable aids for family caregivers of people with dementia. Previous analyses have shown limited effects of these systems and highlighted a number of barriers, including false alarms. In this study, the investigators used data from an ongoing embedded mixed method randomized controlled intervention to describe patterns of alerts and their association with receipt of the RAM system and caregiver outcomes.
