The aim of this study was to evaluate the type and frequency of falls presenting to an inner city casualty department, and to identify modifiable risk factors in these patients. A prospective descriptive study evaluated those over 65 years presenting to an inner city casualty department with falls. Over a 4-week recruitment period, all consenting subjects completed a semi-structured questionnaire regarding their falls and cognitive status. Those with unexplained (UF) or recurrent falls (RF) underwent a more detailed assessment: history and examination, gait and balance assessment, visual acuity measurement and neurocardiovascular investigations (including orthostatic blood pressure, carotid sinus massage and head-up tilt testing). Of 200 patients with falls, 188 were interviewed; 29% could recall a reason for falling (accidental) and 30% had UF or RF. A cohort of 26 cognitively normal patients with UF and RF was fully investigated. In 23/26 patients risk factors for falls were found (median: three risk factors). These included: culprit medication (10), gait abnormalities (9) and carotid sinus hypersensitivity (19). Falls are a common presenting complaint yet a fall is readily explained in less than one-third of cases. Investigation of RF and UF has a high yield for possibly modifiable cardiac and non-cardiac risk factors. Targeted multi-disciplinary rapid assessment of patients attending the Accident and Emergency Department because of a fall might reduce the number of hospital admissions.
本研究的目的是评估前往市中心急诊部门就诊的跌倒类型和频率,并确定这些患者中可改变的风险因素。一项前瞻性描述性研究对65岁以上前往市中心急诊部门就诊的跌倒患者进行了评估。在为期4周的招募期内,所有同意参与的受试者都完成了一份关于其跌倒情况和认知状态的半结构化问卷。那些有不明原因(UF)或反复跌倒(RF)的患者接受了更详细的评估:病史和体格检查、步态和平衡评估、视力测量以及神经心血管检查(包括直立性血压、颈动脉窦按摩和头高位倾斜试验)。在200例跌倒患者中,188例接受了访谈;29%的患者能回忆起跌倒原因(意外),30%的患者有不明原因跌倒或反复跌倒。对26例认知正常的不明原因跌倒和反复跌倒患者进行了全面调查。在26例患者中有23例发现了跌倒的风险因素(中位数:3个风险因素)。这些因素包括:可疑药物(10例)、步态异常(9例)和颈动脉窦过敏(19例)。跌倒虽是常见的就诊主诉,但不到三分之一的病例能轻易解释跌倒原因。对反复跌倒和不明原因跌倒进行调查,对于可能可改变的心脏和非心脏风险因素有很高的检出率。对因跌倒前往急诊部门就诊的患者进行有针对性的多学科快速评估,可能会减少住院人数。
