In this thesis research, we investigate the usability of hand-held display (Tablet PC) and wearable head-mounted display (Google Glass) interfaces and their effect on doctor-patient interaction during clinical ward round in the hospital. We looked at existing literature to identify existing research about our topic. Using a User Centered Interaction Design process we developed a prototype hybrid system that used both a hand-held and head-mounted display. An evaluation of this prototype with a hand-held system and a paper based interface was performed in a simulated patient room with 20 doctors and 5 patients. The participants were observed, surveyed, and interviewed about their experiences. Generally, the patients had a high satisfaction rate and felt the interfaces were not causing the doctors to lose focus on them. The doctors found the hand-held display by itself and existing paper-based interface to be the most usable and least distracting interfaces for accessing patient information during clinical ward rounds.

Thesis (MPhil)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Background: The theoretical / cognitive component of ethics and professionalism teaching to undergraduate medical students at Stellenbosch University (SU) is well developed, but a concern exists about the need for teaching and assessment of clinical ethics and professionalism on ward rounds. Some teaching does take place during clinical rotations in the form of role modelling as part of the hidden curriculum. Opportunities should be created for explicit teaching of ethics and professionalism beyond the hidden curriculum. Assessment of the cognitive component of ethical and professionalism occurs, but assessment of clinical ethics and professionalism during clinical rotations remains a challenge. Methods: This was a non-experimental study and included three subgroups of undergraduate medical students in their clinical years as well as a random sample of educators involved in clinical training. Questionnaires were distributed to the students and educators. This was followed by focus group interviews among the students. Results: A majority of the students (88%) had indicated that they had experienced ethical and professional dilemmas while working in the wards or during ward rounds. The main dilemmas revolved around inadequate consent processes, lack of confidentiality and privacy, disrespect for patients, poor communication and students being expected to perform tasks they were not trained for. An average of 64% of students indicated that ethical and professional issues were not discussed during the clinical rotations in hospitals. Seventy-eight percent of students indicated that they did not feel free to discuss their own feelings or beliefs on ward rounds. All of the educators felt that there was a need for increased teaching and assessment of the medical students during their clinical rotations. Conclusions: Deliberate opportunities need to be created for teaching ethics and professionalism on clinical ward rounds. This could be a shared responsibility between the clinical departments with continuous input throughout the clinical years of study. Strong institutional support and commitment are necessary to make the teaching sustainable and successful. Structured opportunities need to be developed where students can discuss ethical and professional issues in a safe environment. Further research is needed for the development of an appropriate curriculum and assessment tools. / AFRIKAANSE OPSOMMING: Geen opsomming
