To understand how much time residents spend using computers compared with other activities, and what residents use computers for.
This time and motion study was conducted in June and July 2010 at NewYork-Presbyterian/Columbia University Medical Center with seven residents (first-, second-, and third-year) on the general medicine service. An experienced observer shadowed residents during a single day shift, captured all their activities using an iPad application, and took field notes. The activities were captured using a validated taxonomy of clinical activities, expanded to describe computer-based activities with a greater level of detail.
Residents spent 364.5 minutes (50.6%) of their shift time using computers, compared with 67.8 minutes (9.4%) interacting with patients. In addition, they spent 292.3 minutes (40.6%) talking with others in person, 186.0 minutes (25.8%) handling paper notes, 79.7 minutes (11.1%) in rounds, 80.0 minutes (11.1%) walking or waiting, and 54.0 minutes (7.5%) talking on the phone. Residents spent 685 minutes (59.6%) multitasking. Computer-based documentation activities amounted to 189.9 minutes (52.1%) of all computer-based activities time, with 128.7 minutes (35.3%) spent writing notes and 27.3 minutes (7.5%) reading notes composed by others.
The study showed that residents spent considerably more time interacting with computers (over 50% of their shift time) than in direct contact with patients (less than 10% of their shift time). Some of this may be due to an increasing reliance on computing systems for access to patient data, further exacerbated by inefficiencies in the design of the electronic health record.
了解住院医师使用计算机的时间与进行其他活动的时间相比情况如何,以及住院医师使用计算机的用途。
2010年6月和7月,在纽约长老会/哥伦比亚大学医学中心对7名普通内科服务的住院医师(一年级、二年级和三年级)进行了此次时间动作研究。一名经验丰富的观察员在一个白班期间跟踪住院医师,使用iPad应用程序记录他们的所有活动,并做现场笔记。活动通过经过验证的临床活动分类法进行记录,并进行扩展以更详细地描述基于计算机的活动。
住院医师在轮班时间内花364.5分钟(50.6%)使用计算机,而与患者互动的时间为67.8分钟(9.4%)。此外,他们花292.3分钟(40.6%)亲自与他人交谈,186.0分钟(25.8%)处理纸质病历,79.7分钟(11.1%)进行查房,80.0分钟(11.1%)行走或等待,54.0分钟(7.5%)打电话。住院医师花685分钟(59.6%)进行多任务处理。基于计算机的文档活动占所有基于计算机活动时间的189.9分钟(52.1%),其中128.7分钟(35.3%)用于写笔记,27.3分钟(7.5%)用于阅读他人撰写的笔记。
该研究表明,住院医师与计算机互动的时间(超过轮班时间的50%)比与患者直接接触的时间(不到轮班时间的10%)多得多。部分原因可能是越来越依赖计算系统来获取患者数据,而电子健康记录设计的低效率进一步加剧了这种情况。
