It is not uncommon that the introduction of a new technology fixes old problems while introducing new ones. The Veterans Administration recently implemented a comprehensive electronic medical record system (CPRS) to support provider order entry. Progress notes are entered directly by clinicians, primarily through keyboard input. Due to concerns that there may be significant, invisible disruptions to information flow, this study was conducted to formally examine the incidence and characteristics of input errors in the electronic patient record.
Sixty patient charts were randomly selected from all 2,301 inpatient admissions during a 5-month period. A panel of clinicians with informatics backgrounds developed the review criteria. After establishing inter-rater reliability, two raters independently reviewed 1,891 notes for copying, copying errors, inconsistent text, inappropriate object insertion and signature issues.
Overall, 60% of patients reviewed had one or more input-related errors averaging 7.8 errors per patient. About 20% of notes showed evidence of copying, with an average of 1.01 error per copied note. Copying another clinician's note and making changes had the highest risk of error. Templating resulted in large amounts of blank spaces. Overall, MDs make more errors than other clinicians even after controlling for the number of notes.
Moving towards a more progressive model for the electronic medical record, where actions are recorded only once, history and physical information is encoded for use later, and note generation is organized around problems, would greatly minimize the potential for error.
引入新技术解决旧问题的同时引入新问题的情况并不罕见。退伍军人管理局最近实施了一个综合电子病历系统(CPRS)以支持医疗服务提供者下达医嘱。病程记录主要由临床医生通过键盘输入直接录入。由于担心可能对信息流造成重大的、不可见的干扰,开展了本研究以正式检查电子病历中输入错误的发生率和特征。
在5个月期间从所有2301例住院患者中随机抽取60份病历。由具有信息学背景的临床医生小组制定审查标准。在确定评分者间信度后,两名评分者独立审查了1891份记录,检查复制、复制错误、文本不一致、不适当的对象插入和签名问题。
总体而言,60%接受审查的患者存在一个或多个与输入相关的错误,平均每位患者有7.8个错误。约20%的记录有复制迹象,每份复制记录平均有1.01个错误。复制另一位临床医生的记录并进行修改产生错误的风险最高。模板化导致大量空白。总体而言,即使在控制记录数量后,医生犯的错误也比其他临床医生多。
朝着更先进的电子病历模式发展,即操作只记录一次、病史和体格检查信息进行编码以供后续使用、记录生成围绕问题进行组织,将极大地降低出错的可能性。
