Comparative StudyComparing response time, errors, and satisfaction between text-based and graphical user interfaces during nursing order tasks.
Despite the general adoption of graphical users interfaces (GUIs) in health care, few empirical data document the impact of this move on system users. This study compares two distinctly different user interfaces, a legacy text-based interface and a prototype graphical interface, for differences in nurses' response time (RT), errors, and satisfaction when the interfaces are used in the performance of computerized nursing order tasks. In a medical center on the East Coast of the United States, 98 randomly selected male and female nurses completed 40 tasks using each interface. ⋯ Therefore, the results indicated that the use of a prototype GUI for nursing orders significantly enhances user performance and satisfaction. Consideration should be given to redesigning older user interfaces to create more modern ones by using human factors principles and input from user-centered focus groups. Future work should examine prospective nursing interfaces for highly complex interactions in computer-based patient records, detail the severity of errors made on line, and explore designs to optimize interactions in life-critical systems.

Implementation of clinical guidelines via a computer charting system: effect on the care of febrile children less than three years of age.
The authors have shown that clinical guidelines embedded in an electronic medical record improved the quality, while lowering the cost, of care for health care workers who incurred occupational exposures to body fluid. They seek to determine whether this system has similar effects on the emergency department care of young children with febrile illness. ⋯ The intervention markedly improved documentation, had little effect on the appropriateness of the process of care, and had no effect on charges. Results for the febrile child module differ from those for the module for occupational blood and body fluid exposure (a more focused and straightforward medical condition), underscoring the need for implementation methods to be tailored to specific clinical complaints.
