A Frailty Index Based on Common Laboratory Tests in Comparison With a Clinical Frailty Index for Older Adults in Long-Term Care Facilities

摘要

Introduction: Easily employed measures of frailty are needed in the evaluation of elderly people. Recently, a frailty index (FI) based on deficits in commonly used laboratory tests (the FI-LAB) has been proposed. To address the usefulness of the FI-LAB in long-term care (LTC) settings, we studied institutionalized participants in the Canadian Study of Health and Aging first clinical examination database. Our objectives were to compare the FI-LAB with a clinical FI LTC (FI-Clinical-LTC) focused on common health deficits seen in LTC and to assay its relationship with mortality.
