[Clinical classification of fall risk using visually obtained information at a memory clinic].

Aim: There are few studies concerning the classification of fall risk by nurses without established fall risk assessment tools. In the present study, clinical classification of fall risk using visually obtained information was compared with the assessment of fall risk in order to evaluate the rationale and validity of the clinical classification of fall risk by nurses.

Methods: New patients who visited the center of comprehensive care and research for memory disorders at the National Center for Geriatrics and Gerontology were enrolled in the present study.Day-shift nurses separately recorded the clinical classification of fall risks through visually obtained information during the 10-minutes waiting time for outpatients.Fall risk assessments such as the Fall Risk Index and Timed Up & Go test, were performed by non-nurse medical staffs. Data were analyzed by an independent researcher who was not involved in obtaining clinical information.

Results: Nurse's clinical classification of fall risk using visually obtained information correlated well with Fall Risk Index, Timed Up & Go test, One-leg Standing test and Dorsiflex meter. In addition, subjects classified as having high fall risk were more frequently judged to be frail than classes of moderate or little fall-risk.

Conclusion: Nurse's clinical classification of fall risk using visually obtained information was judged on their integrated impression including their evaluation of the muscle strength, gait speed and balance.
