Background. Clinicians are often unaware of the many existing scales for id
entifying fall risk and are uncertain about how to select an appropriate on
e. Our purpose was to summarize existing fall risk assessment scales to ena
ble more informed choices regarding their use.
Methods. After a systematic literature search, 21 articles published from 1
984 through 2000 describing 20 fall risk assessments were reviewed independ
ently for content and validation by a panel of five reviewers using a stand
ardized review form. Fourteen were institution-focused nursing assessment s
cales, and six were functional assessment scales.
Results. The majority of the scales were developed for elderly populations.
mainly in hospital or nursing home settings. The patient characteristics a
ssessed were quite similar across the nursing assessment forms. The time to
complete the form varied from less than I minute to 80 minutes. For those
scales with reported diagnostic accuracy, sensitivity varied from 43% to 10
0% (median = 80%), and specificity varied from 38% to 96% (median = 75%). S
everal scales with superior diagnostic characteristics were identified.
Conclusions. A substantial number of fall risk assessment tools are readily
available and assess similar patient characteristics. Although their diagn
ostic accuracy and overall usefulness showed wide variability, there are se
veral scales that can be used with confidence as part of an effective falls
prevention program. Consequently, there should be little need for faciliti
es to develop their own scales. To continue to develop fall risk assessment
s unique to individual facilities may be counterproductive because scores w
ill not be comparable across facilities.
