During a 22-month period in 1981-82, 250 falls were recorded at a 152-bed acute care specialty hospital in a United States metropolitan area. Rates were highest for patients age 65 years and older and for patients admitted with mental disorders. Patients who had fallen once had a subsequent fall rate of 91.7 per 1,000 patients compared to an overall rate of 18.7 for first falls. Half the falls occurred in or enroute to the private bathroom attached to each room. Only three falls resulted in injury sufficient to prolong hospital stay.
在1981年至1982年的22个月期间，美国一个大都市地区一家拥有152张床位的急性护理专科医院记录了250起跌倒事件。65岁及以上的患者以及因精神障碍入院的患者跌倒率最高。跌倒过一次的患者随后的跌倒率为每1000名患者91.7次，而首次跌倒的总体发生率为18.7次。一半的跌倒事件发生在每个房间附带的私人浴室或前往浴室的途中。只有三起跌倒导致了足以延长住院时间的伤害。
