Impact of the instruction form on the training success of lay users in medical devices - Deriving of design recommendations
Master's thesis of Anja Marckwardt
Nowadays more and more medical devices are being used by patients independently of medical staff. The number of patients who are using such devices which are necessary to treat their condition is constantly on the increase. It is imperative that the equipment is used safely and properly. This is to avoid potential injuries and to ensure the efficacy of the treatment.
There are many ways of learning to handle medical devices in the correct manner. One is learning through instructions which use different kinds of media to impart information. It can be done by methods ranging from traditional print media to interactive online tutorials.
This study attends to analyze the relative merits of different training methods on lay users. In order to accomplish this aim, four related study questions were derived. In the study, 48 subjects took part aged from 21 to 43. They were randomly allocated to four equally sized groups. All subjects had to learn the handling of two devices for the treatment of diabetes. Therefore, they either used a static or dynamic instruction. By using a methodical triangulation, the evaluation was possible from different angles. It was of priority to analyze the subjects’ mental models as well as their behavior while performing the tasks.
