Characteristics of Single Fallers and Recurrent Fallers among Hospital In-Patients

BACKGROUND: Recurrent fallers constitute a minority of patients who fall but contribute considerably to the total number of falls recorded. OBJECTIVE: To study the characteristics of recurrent fallers in a hospital setting. METHODS: In a prospective observational study we investigated the characteristics of 1,025 patients admitted to a geriatric non-acute hospital. Patients were followed until discharge and were classified as non-fallers, single fallers or recurrent fallers. RESULTS: We identified 824 non-fallers, 136 single fallers and 65 recurrent fallers contributing 175 falls. Compared to non-fallers, recurrent fallers were more likely to have pre-admission falls (p = 0.004), confusion (p < 0.0001), an unsafe gait (p = 0.0001) and be on tranquillisers (p = 0.018) and antidepressants (p = 0.006). They had longer stays in hospital (p < 0.0001) and more nursing home discharges (p = 0.0001). There was considerable overlap with risk factors for single fallers but compared to this group they were more likely to be confused (p = 0.027), and on antidepressant medication (p = 0.009). They also had a longer length of stay (p < 0.001) and more nursing home discharges (p = 0.03). Confusion (p = 0.0001), unsafe gait (p = 0.0006) and antidepressants (p = 0.018) were independently associated with recurrent falls. CONCLUSIONS: It is important to recognise the risk factors that prospectively identify a recurrent faller because of the significant contribution to total falls by a relatively small number of patients. This may be useful not only in trying to reduce total falls but also in trying to reduce injury.
