摘　　要：Background Falls are the most frequently reported adverse events in inpatient settings. We conducted a retrospective case-control study of inpatient falls within aged care wards in a tertiary hospital to investigate the associated characteristics of elderly patients suffering from falls and fall-related characteristics. Methods Consecutive retrospective cross-sectional design spanned July 2006 to December 2008. Patient group： Information on all aged care inpatients who suffered from 1 or more falls was extracted from Incident Information Management System （IIMS）. Further details about the particular admission（s） were obtained from patients＇ medical records, e.g., patients＇ characteristics and circumstances surrounding the falls. Randomly selected aged care patients who did not suffer from a fall and who were discharged from the hospital in the same period served control group. Characteristics among patients with single fall and recurrent falls, as well as non-railers were compared. Results Of the 438 falls evaluated, 71.9% occurred in patients＇ room and 18.9% in patients＇ bathroom/toilet. The common activities were moving/transferring and taking shower/toileting, respectively, 70.3%, 12.1% while occurring falls; and time of falls had a high peak during 9：00-11：00 a.m. Many were unassisted while falling. The common contributing factors for fall were intrinsic factors. Patients with recurrent falls were more likely to have lower Mini-Mental State Examination （MMSE） score. Logistic regression analysis showed length of stay longer than five weeks, dementia and stroke were independent risk factors for recurrent falls; and living in hostel/nursing home preadmission, needing assistance with mobility, cognitive impairment, stroke, incontinence and arthritis/osteoporosis were independent risk factors for fall. Conclusions In an aged care ward, falls are independently associated with recurrent factors. Cognitive impairment/dementia was a strong risk factor for falls, and main causes leading to falBackground Falls are the most frequently reported adverse events in inpatient settings.
