Aim : A prospective study was conducted from June 1, 2002 to May 31, 2003, to investigate the occurrence of accidental falls among inpatients from an acute care university hospital. We also developed and evaluated a fall risk assessment instrument.

Methods : Subjects included 3,912 patients (2,146 males ; 1,766 females) from an acute care university hospital. On the first day of admission to the hospital, nurses evaluated subjects for fall risk using the 9-item assessment instrument.

Results : During the study period, there were 218 subjects who fell ; the fall rate was 5.87% for males and 5.21% for females. There were significant age differences between the subjects who fell[70.1 (±13.2) years old] and those who did not fall[59.0 (±16.6) years old] (p<0.05). There were 364 cases of accidental falls, with a total of 267 (73.35%) injuries that occurred as a result of an accidental fall. Twenty male subjects sustained two or more falls that resulted in 143 (59.89%) incidents of injury. Nine items were significantly associated with falling : Previous fall experience, Gait disorder, Requires assistance with walking, Symptoms of dizziness and feeling dizzy when standing up, Psychotic manifestations, Disorientation, Wandering, Incontinence of bowels, and Taking medication. Multiple logistic regression was conducted to examine independent contribution of risk factors for falls. Four items were significantly related with falling : Previous fall experience, Psychotic manifestations, Incontinence of bowels, and Taking medication. The range of relative risk was 1.11─2.617. As a result, the cutoff point was 2, sensitivity was 0.689, and specificity was 0.595.

Conclusion : Our findings suggest that our assessment instrument was effective in the evaluation of fall prevention for an acute care university hospital.
