This study examines the impact of physician order entry (POE) on nurses perceptions of work, quality of care, and nurse/physician communication. Four hospitals that have implemented a computerized order-entry system with POE were compared with four similar hospitals using the same computerized system with clerk order entry only. Three factors were extracted from the 29 item survey using principal component extraction with varimax rotation that accounted for 16.5%, 12.4% and 8.7% of the variance respectively. Three scales were constructed from these factors measuring perceptions of impact of the information system on the quality of care, job, control, and nurse/physician communication. Nurses working in the POE environment rated their computer system as having greater impact on the quality of care and lower ratings of perceived control than those working in non-POE environments. No differences were found between nurses working in POE environments and those working in POE in terms of their ratings of frequency of contact and ease of access to physicians.
本研究考察了医生医嘱录入（POE）对护士工作认知、护理质量以及护士与医生沟通的影响。将四家已实施带有POE的计算机化医嘱录入系统的医院与四家仅使用带有文员医嘱录入的相同计算机化系统的类似医院进行了比较。使用主成分提取和方差最大化旋转从29项调查中提取了三个因素，它们分别占方差的16.5%、12.4%和8.7%。基于这些因素构建了三个量表，用于衡量信息系统对护理质量、工作、控制权以及护士与医生沟通的影响认知。与在非POE环境中工作的护士相比，在POE环境中工作的护士认为其计算机系统对护理质量的影响更大，而对感知控制权的评分更低。在POE环境中工作的护士与在非POE环境中工作的护士在与医生接触频率和联系便利性的评分方面没有差异。
