The objective of our study was to describe the characteristics of falls in a radiology department.
The departmental incident report database was retrospectively searched for fall incidents that occurred from March 2006 through October 2008. During that period, 1,801,275 radiologic examinations were performed in our department and there were 82 falls, yielding an incidence of 0.46 per 10,000 examinations. We collected patient information, associated factors, specific circumstances surrounding each incident, the location of each incident, and patient outcome.
Eighty-two falls occurred involving 82 patients (35 males, 47 females; mean age, 58.2 years; range, 3-92 years): 66 falls (80%) involved outpatients; 11, inpatients; and five, visitors accompanying a patient. Radiography and CT-MRI units were the top two most common locations of falls (45/82, 55%). Thirty-six events (36/82, 44%) were directly related to a radiologic examination. Most falls were witnessed (61/82, 74%) and unassisted (50/82, 61%), and a majority occurred while the patient was standing or ambulating (59/82, 72%). Most patients (70/82, 85%) had at least one predisposing factor for falling. Sixteen patients (16/82, 20%) had fallen within the previous 3 months. Twenty-four falls (24/82, 29%) resulted in a documented injury (17 minor, seven moderate or severe) with one patient dying. Patients were more likely to be injured if they fell while ambulating (p = 0.0257, univariate analysis) or if they were taking antihypertensive medication (p = 0.02, multivariate analysis).
Falls were uncommon in the radiology department studied; however, they can result in significant morbidity and mortality.
本研究旨在描述放射科跌倒事件的特征。
我们回顾性地检索了 2006 年 3 月至 2008 年 10 月期间放射科事件报告数据库中发生的跌倒事件。在此期间，我们科室共进行了 1801275 次放射学检查，发生跌倒事件 82 例，发生率为每 10000 次检查 0.46 例。我们收集了患者信息、相关因素、每个事件的具体情况、事件发生地点和患者结局。
共发生 82 例患者跌倒事件（35 例男性，47 例女性；平均年龄 58.2 岁；年龄范围 3-92 岁）：66 例（80%）为门诊患者，11 例为住院患者，5 例为陪检患者。放射科和 CT-MRI 检查室是跌倒事件最常发生的两个地点（45/82，55%）。36 例事件（36/82，44%）与放射学检查直接相关。大多数跌倒事件有目击者（61/82，74%）且未得到帮助（50/82，61%），大多数发生在患者站立或行走时（59/82，72%）。大多数患者（70/82，85%）至少存在一个跌倒的诱发因素。16 例患者（16/82，20%）在过去 3 个月内跌倒过。24 例跌倒事件（24/82，29%）导致患者受伤（17 例为轻度，7 例为中度或重度），其中 1 例患者死亡。与无受伤患者相比，跌倒时正在行走（p=0.0257，单因素分析）或正在服用降压药（p=0.02，多因素分析）的患者更容易受伤。
在所研究的放射科中，跌倒事件并不常见，但可导致严重的发病率和死亡率。
