Incidence and Risk Factors of Poststroke Falls After Discharge From Inpatient Rehabilitation.

Objective: To investigate the incidence of falls and risk factors for falls in persons who had a stroke. Design: Telephone survey. Setting: Tertiary university hospital. Patients and Methods: Patients who had a stroke and were admitted to the rehabilitation unit between April 2006 and July 2008 were listed and contacted by telephone from February 2009 to August 2009. Main Outcome Measurements: Information obtained from the interviews, which were performed 20 ± 8 months after discharge from inpatient rehabilitation, included demographic data, information about falls, and current ambulatory function. After the telephone interview, medical records of participants during admission were reviewed. Results: Of the 404 enrolled patients, 330 were included in the analysis. Of the 330 patients, 62 (19%) had a history of a fall after stroke onset. Of 222 ambulatory patients, 51 patients (23%) fell. Falls frequently occurred in winter, and most falls occurred indoors (70%). Twenty-nine percent of patients experienced repeated falls. About half of those who fell were injured, and 11% sustained fractures. Patients who had a stroke and had severe deficits showed a lower probability of poststroke falls. In a subgroup analysis of patients with ambulatory capacity, left-sided hemiplegia/hemiparesis was associated with an increased risk of falls. Conclusions: This study reveals a high incidence of poststroke falls after discharge from inpatient rehabilitation. More caution should be taken for patients with ambulatory ability and left hemiplegia/hemiparesis because they are more vulnerable to falls after a stroke. An increased prevalence of fear of falling in people who fell suggests that an appropriate intervention to reduce fear of falling should be provided to patients who have had a stroke.
