Physician satisfaction with electronic medical records has often been poor. Usability has frequently been identified as a source for decreased satisfaction. While surveys can identify many issues, and are logistically easier to administer, they may miss issues identified using other methods This study sought to understand the level of physician satisfaction and usability issues associated with a critical care clinical information system (eCritical Alberta) implemented throughout the province of Alberta, Canada.
All critical care attending physicians using the system were invited to participate in an online survey. Questions included components of the User Acceptance of Information Technology and Usability Questionnaire as well as free text feedback on system components. Physicians were also invited to participate in a think aloud test using simulated scenarios. The transcribed think aloud text and questionnaire were subjected to textual analysis.
82% of all eligible physicians completed the on-line survey (n = 61). Eight physicians were invited and seven completed the think aloud test. Overall satisfaction with the system was moderate. Usability was identified as a significant factor contributing to satisfaction. The major usability factors identified were system response time and layout. The think aloud component identified additional factors beyond those identified in the on-line survey.
This study found a modestly high level of physician satisfaction with a province-wide clinical critical care information system. Usability continues to be a significant factor in physician satisfaction. Using multiple methods of evaluation can capture the benefits of a large sample size and deeper understanding of the issues.
医生对电子病历的满意度通常较低。可用性经常被认为是降低满意度的一个原因。虽然调查可以确定许多问题，并且在管理上更容易进行，但它们可能会错过使用其他方法识别的问题。本研究旨在了解与整个加拿大阿尔伯塔省实施的关键护理临床信息系统（eCritical Alberta）相关的医生满意度和可用性问题的水平。
所有使用该系统的重症监护主治医生都被邀请参与在线调查。问题包括信息技术和可用性问卷的组成部分，以及对系统组成部分的自由文本反馈。还邀请医生使用模拟场景进行出声思考测试。记录下来的出声思考文本和问卷都经过了文本分析。
61 名符合条件的医生中有 82%完成了在线调查（n=61）。邀请了 8 名医生，其中 7 名完成了出声思考测试。总体而言，医生对系统的满意度为中等。可用性被认为是影响满意度的一个重要因素。确定的主要可用性因素是系统响应时间和布局。出声思考部分确定了在线调查中未识别出的其他因素。
本研究发现，医生对全省范围的临床重症监护信息系统的满意度较高。可用性仍然是医生满意度的一个重要因素。使用多种评估方法可以同时获得大量样本的优势，并深入了解问题。
