One of the shortcomings of the pathways-to-care literature is the lack of empirical support for the validity of the data collection methods. This study uses three common formats to collect retrospective pathways-to-care data for adults who have been diagnosed with possible or probable Alzheimer's disease (AD) and compares indicators to evaluate their relative validity. Forty family caregivers of adults diagnosed with possible or probable AD were recruited from the caregiver registry of the Boston University Alzheimer's Disease Core Center (BU ADCC). In each of three formats (questionnaire, structured interview, and medical record review), data were collected regarding four key events in the pathway to dementia care: first appearance of symptoms, first verbalized recognition of symptoms, first effort to seek professional help, and first diagnosis by a professional. In addition to the dates of these events, researchers attempted to determine: the first verbalized concern about the symptoms, who first sought professional help, what professional was first approached, and what professional made the first diagnosis. In a consensus meeting, data collected in all three formats were reviewed, and a consensus on the most likely answers to all questions was recorded and compared to data collected in each format. The results suggest that the three formats are not equivalent in terms of concurrent validity. While substantial agreement is found among data collection methods, the validity of the structured interview format and the medical record review is most consistently supported by the data in this study. Questionnaire data resulted in underestimates of delays and correlated poorly with other data sources, including the consensus judgment. Recommendations for pathways-to-care data collection procedures that maximize validity are discussed.
A wide-range of respite services have been developed to meet the needs of families who care for the chronically ill and frail elderly. Institutional respite is a particular service that provides inpatient care to patients and offers their families temporary relief from the strain of continuous caregiving. This paper describes a two-week in-hospital respite program specifically designed for patients with Alzheimer's disease. Patients are profiled on the use of respite, sociodemographic characteristics, functional levels, and their dispositional outcome following respite.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
