Casebook: a virtual patient iPad application for teaching decision-making through the use of electronic health records

Abstract

BackgroundVirtual Patients are a well-known and widely used form of interactive software used to simulate aspects of patient care that students are increasingly less likely to encounter during their studies. However, to take full advantage of the benefits of using Virtual Patients, students should have access to multitudes of cases. In order to promote the creation of collections of cases, a tablet application was developed which makes use of electronic health records as material for Virtual Patient cases. Because electronic health records are abundantly available on hospital information systems, this results in much material for the basis of case creation.ResultsAn iPad-based Virtual Patient interactive software system was developed entitled Casebook. The application has been designed to read specially formatted patient cases that have been created using electronic health records, in the form of X-ray images, electrocardiograms, lab reports, and physician notes, and present these to the medical student. These health records are organised into a timeline, and the student navigates the case while answering questions regarding the patient along the way. Each health record can also be annotated with meta-information by the case designer, such as insight into the thought processes and the decision-making rationale of the physician who originally worked with the patient. Students learn decision-making skills by observing and interacting with real patient cases in this simulated environment. This paper discusses our approach in detail.ConclusionsOur group is of the opinion that Virtual Patient cases, targeted at undergraduate students, should concern patients who exhibit prototypical symptoms of the kind students may encounter when beginning their first medical jobs. Learning theory research has shown that students learn decision-making skills best when they have access to multitudes of patient cases and it is this plurality that allows students to develop their illness scripts effectively. Casebook emphasises the use of pre-existing electronic health record data as the basis for case creation, thus, it is hoped, making it easier to produce cases in larger numbers. By creating a Virtual Patient system where cases are built from abundantly available electronic health records, collections of cases can be accumulated by institutions.

Medical Students’ Experiences and Outcomes Using a Virtual Human Simulation to Improve Communication Skills: Mixed Methods Study

“…Recent research has examined the value of virtual patients, broadly, applied to improve medical decision making, such as creating accurate virtual patient cases derived from electronic health records to train decision making [37]. Our work further adds to the literature about VHs, focusing specifically on communication training, critical to decision making and the entire health care encounter.…”

Virtual medical learning: a comprehensive study on the role of new technologies

“…However, virtual patients can also be complicated and costly to develop (Huang et al , 2007). Bloice et al (2014) created a virtual patient system that uses the abundance of electronic health records found in hospital information systems. They believed this system has several inherent advantages, such as cost reduction.…”

An evaluation of medical residents utilization of tablet computers

“…Apps such as Casebook (a Virtual Patient teaching application) can further improve acceptance of tablet computing in medical education because developers are now focusing specifically on the medical student and designing the software for them, keeping both sound human factors principles and teaching methods in mind (Bloice, Simonic, & Holzinger, 2014a, 2014b.…”
