Abstract

This study examined various means of data input and display of medical monitoring coagulation function in Internet sites for the use of elderly population

Study design:

 Three experimental Internet web-based sites were built for purposes of our study. The participants inserted their medical test results and answered six questions based on their report in each of the three websites. The three websites differentiated in their data input display (free-text fields, menus, and visual buttons), and visualization methods (table, graph, and calendar formats).

The research group included 50 participants from two age groups (elderly and young participants). Both groups had similar experience in computer use and Internet surfing. During the course of the experiment, physiological indicators for stress (pulse, sweet, temperature, respiration rate, and muscle tension) were collected from the participants (with their knowledge and consent).

Findings:

A significant preference for data input via menus was identified at both age groups, based on measurement of time for task completion, accuracy and stress. The elderly expressed their preference for performing data input via menus; the younger group did not express a clear preference for any particular data input method.

Both age groups, exhibited significantly better performance, when looking for a defined data value (based on time and accuracy of results), in tabular format, as opposed to graphic format. In contrast, when looking for an exceptional data value or a trend in values, there was a preference for graphic over tabular display format. In both age groups an increase in stress level was measured while viewing a graph. Both age groups expressed a preference for graphic over tabular data display.

In summary, we identify a preference, independent of age group, for data input via menus. Additionally, we conclude that, independent of age group; tabular display is preferred when searching for a specific data, while graphic display is preferred when looking for an exceptional item or for an overall trend in information.

Our results demonstrate that older adults can perform Internet tasks as well as, though slower than, young people

It is our belief that There are evidences that interactive computer systems like presented in our study, by which the patient continuously takes care of his own data, can improve clinical outcome and increase patient’s satisfaction.
