Abstract

Today, in most medical Hospitals and clinics, Doctors use computers and computerized files (Electronic Medical Records - EMR). However, despite the great technological revolution and the welcome changes, new and old problems came to light which were not treated yet. So for instance, a large amount of software programs appeared, utilizing a display whose efficiency was not empirically inspected.  The possible consequence of this has an adverse effect on the diagnostic process of the doctor. On the other hand, there are Electronic Medical Records that display their information similarly to the manual files, instead of evaluating their old visual displays with newer and improved displays.

This research is focused in examining the preferred laboratory data display. In this framework, three display systems were checked: table display, bar graph display along a time axis planned for the experiment, and also an integrative display along a time axis planned for the experiment. The above systems were shown in EMR also programmed for the experiment. Thirty Doctors during their internship in the 'Carmel' Hospital, participated in the research. The research checked three types of routine assignments, which Doctors perform while reading laboratory data: finding a specific data in a determined time, maximum or minimum data identification and trend identification. During the experience the participants were connected to monitored physiological changes software. The outcome proved that on the time index, no differences were found between the table display to the bar graph display in the three types of tasks and between all displays on the first and second missions of identifying a specified data in determined time and maximal or minimal data identification. On the other hand, the identification of structure and trend task, took longer time in the integrative display than in the other two displays. On the accuracy level, the number of mistakes was negligible in all three displays. However, on the satisfaction index, the table and bar graph display were preferred over the integrative display. On the physiological indices, no link with the other levels was found. The research result strengthens the view that it is not enough to plan a display according to correct instructions or rely on quality evaluation of people. Similar to medicine which is thoroughly checked and evaluated among different people before being marketed, here too when it comes to human life, the validity and efficiency of the display must be properly checked.
