Abstract:
The Johns Hopkins Fall Risk Assessment Tool (JHFRAT) is widely used but few studies have examined its psychometric properties. We examined the predictive validity of the JHFRAT for 13 574 patient admissions to medicine units at a large academic medical center in 2014. There were 204 patient falls reported. While patients who fell had higher JHFRAT total scores, a majority of patients who fell were classified by the JHFRAT as moderate or low risk.
