Objective: Caring for the elderly with dementia imposes a substantial burden on family members and likely accounts for more than half of the total cost of dementia for those living in the community. However, most past estimates of this cost were derived from small, nonrepresentative samples. We sought to obtain nationally representative estimates of the time and associated cost of informal caregiving for the elderly with mild, moderate, and severe dementia.Design: Multivariable regression models using data from the 1993 Asset and Health Dynamics Study, a nationally representative survey of people age 70 years or older (N = 7,443).Setting: National population-based sample of the community-dwelling elderly.Main Outcome Measures: Incremental weekly hours of informal caregiving and incremental cost of caregiver time for those with mild dementia, moderate dementia, and severe dementia, as compared to elderly individuals with normal cognition. Dementia severity was defined using the Telephone Interview for Cognitive Status.Results: After adjusting for sociodemographics, comorbidities, and potential caregiving network, those with normal cognition received an average of 4.6 hours per week of informal care. Those with mild dementia received an additional 8.5 hours per week of informal care compared to those with normal cognition (P < .001), while those with moderate and severe dementia received an additional 17.4 and 41.5 hours (P < .001), respectively. The associated additional yearly cost of informal care per case was 3,630 dollars for mild dementia, 7,420 dollars for moderate dementia, and 17,700 dollars for severe dementia. This represents a national annual cost of more than 18 billion dollars.Conclusion: The quantity and associated economic cost of informal caregiving for the elderly with dementia are substantial and increase sharply as cognitive impairment worsens. Physicians caring for elderly individuals with dementia should be mindful of the importance of informal care for the well-being of their patients, as well as the potential for significant burden on those (often elderly) individuals providing the care.

Objective: de Quervain disease is a stenosing tenosynovitis of the first dorsal wrist compartment. The purpose of this study was to determine whether focal radial styloid abnormality (cortical erosion, sclerosis, or periosteal bone apposition) as shown by radiography can be an indicator of de Quervain tenosynovitis., Materials and Methods: A retrospective review of 49 radiographs from 45 patients in whom the clinical diagnosis of de Quervain tenosynovitis was confirmed (positive findings on Finkelstein's test) and 64 radiographs from 62 asymptomatic patients was carried out independently by two musculoskeletal radiologists in a blinded fashion. Findings on radiographs were assessed for focal radial styloid abnormality and assigned a diagnostic grade (1, definitely normal; 2, probably normal; 3, equivocal; 4, probably abnormal; 5, definitely abnormal). Receiver operating characteristic curves were constructed and compared. Kappa statistics for interobserver and intraobserver variability were calculated., Results: The presence of focal radial styloid abnormality correlated significantly with the presence of de Quervain tenosynovitis (p < 0.05). The areas under the receiver operating characteristic curves for each reviewer equaled 0.71 and 0.76. Kappa values for interobserver variability equaled 0.44 (moderate agreement), and intraobserver variability equaled 0.62 (substantial agreement)., Conclusion: Focal radial styloid abnormality is an indicator of de Quervain stenosing tenosynovitis of the wrist.

Purpose: As the United States population ages, the increasing prevalence of cancer is likely to result in higher direct medical and nonmedical costs. Although estimates of the associated direct medical costs exist, very little information is available regarding the prevalence, time, and cost associated with informal caregiving for elderly cancer patients., Materials and Methods: To estimate these costs, we used data from the first wave (1993) of the Asset and Health Dynamics (AHEAD) Study, a nationally representative longitudinal survey of people aged 70 or older. Using a multivariable, two-part regression model to control for differences in health and functional status, social support, and sociodemographics, we estimated the probability of receiving informal care, the average weekly number of caregiving hours, and the average annual caregiving cost per case (assuming an average hourly wage of $8.17) for subjects who reported no history of cancer (NC), having a diagnosis of cancer but not receiving treatment for their cancer in the last year (CNT), and having a diagnosis of cancer and receiving treatment in the last year (CT)., Results: Of the 7,443 subjects surveyed, 6,422 (86%) reported NC, 718 (10%) reported CNT, and 303 (4%) reported CT. Whereas the adjusted probability of informal caregiving for those respondents reporting NC and CNT was 26%, it was 34% for those reporting CT (P <.05). Those subjects reporting CT received an average of 10.0 hours of informal caregiving per week, as compared with 6.9 and 6.8 hours for those who reported NC and CNT, respectively (P <.05). Accordingly, cancer treatment was associated with an incremental increase of 3.1 hours per week, which translates into an additional average yearly cost of $1,200 per patient and just over $1 billion nationally., Conclusion: Informal caregiving costs are substantial and should be considered when estimating the cost of cancer treatment in the elderly.
