Caregiver burden should be evaluated during geriatric assessment.

This study examines the relationship between caregiver burden and use of long-term care services following geriatric assessment. One hundred nine older subjects underwent comprehensive assessment, which included a questionnaire completed by the primary caregiver to assess the sense of burden in providing care. Logistic regression was used to identify independent predictors of service use at 12 months. Among measures of the older person's cognitive and physical abilities, only activities of daily living predicted increased use of services. When the measure of caregiver burden was added, it also entered as an independent predictor, which significantly improved the prediction of service use (chi 2 = 5.9, P less than .02). In a separate analysis, caregiver burden predicted both the use of home services and nursing-home placement. During longitudinal follow-up, the measure of burden decreased over 12 months for the sample, with the greatest reduction in burden occurring for caregivers whose relative was placed in a nursing home. The fact that caregiver burden was the most important factor in determining who would use formal services suggests that burden should be evaluated as part of geriatric assessment.
