Fidelity Considerations for Simulation-Based Usability Assessments of Mobile ICT for Hospitals

Changes in medical training and culture have reduced the acceptability of the traditional apprenticeship style training in medicine and influenced the growth of clinical skills training. Simulation is an educational technique that allows interactive, and at times immersive, activity by recreating all or part of a clinical experience without exposing patients to the associated risks. The number and range of commercially available technologies used in simulation for education of health care professionals is growing exponentially. These range from simple part-task training models to highly sophisticated computer driven models. This paper will review the range of currently available simulators and the educational processes that underpin simulation training. The use of different levels of simulation in a continuum of training will be discussed. Although simulation is relatively new to medicine, simulators have been used extensively for training and assessment in many other domains, most notably the aviation industry. Some parallels and differences will be highlighted.

Little is known about the effects of the electronic health record (EHR) on physician-patient encounters. The objectives of this study were to identify the factors that influence the manner by which physicians use the EHR with patients. This ethnographic study included 4 qualitative components: 80 hours of participant observation in 4 primary care offices in the Pacific Northwest; individual interviews with 52 patients, 12 office staff members, 23 physicians, and 1 nurse-practitioner; videotaped reviews of 29 clinical encounters; and 5 focus-group interviews with physicians and computer advocates. The main outcome measures were factors that influence how physicians use the EHR. Researchers qualitatively derived these factors through serial reviews of data. This study identified 14 factors that influence how EHRs are used and perceived in medical practice today. These factors were categorized into 4 thematic domains: (1) spatial--effect of the physical presence and location of EHRs on interactions between physicians and patients; (2) relational--perceptions of physicians and patients about the EHR and how those perceptions affected its use; (3) educational--issues of developing physicians' proficiency with and improving patients' understandings about EHR use; and (4) structural--institutional and technological forces that influence how physicians perceived their use of EHR. This study found that the introduction of EHRs into practice influences multiple cognitive and social dimensions of the clinical encounter. It brings into focus important questions that through further inquiry can determine how to make best use of the EHR to enhance therapeutic relationships.
