Structure Communication

We utilized simulated patient scenarios in a virtual environment to improve students’ communication skills during handovers. To determine how students performed during the scenarios, we assessed several behaviors: structured communication, closed-loop communication, and asking clarification questions. Results revealed that the students’ performance was stronger in the first area (structure communication) and weaker in the second (closed-loop communication) and third (asking clarifying questions) areas.

Abstract Background Verbal and non-verbal communication, as well as empathy are central to patient-doctor interactions and have been associated with patients’ satisfaction. Non-verbal communication tends to override verbal messages. The aim of this study was to analyze how medical students use verbal and non-verbal communication using two different educational approaches, student role play (SRP) and actor simulated patient (ASP), and whether the non-verbal behaviour is different in the two different poses. Methods Three raters evaluated 20 students playing the doctor role, 10 in the SRP group and 10 in the ASP group. The videos were analyzed with the Calgary-Cambridge Referenced Observation Guide (CCG) and, for a more accurate evaluation of non-verbal communication, we also evaluated signs of nervousness, and posture. Empathy was rated with the CARE questionnaire. Independent Mann Whitney U tests and Qhi square tests were performed for statistical analysis. Results From the 6 main tasks of the CCG score, we obtained higher scores in the ASP group for the task ‘Gathering information’ (p = 0.0008). Concerning the 17 descriptors of the CCG, the ASP group obtained significantly better scores for ‘Exploration of the patients’ problems to discover the biomedical perspective’ (p = 0.007), ‘Exploration of the patients’ problems to discover background information and context’ (p = 0.0004) and for ‘Closing the session – Forward planning’ (p = 0.02). With respect to non-verbal behaviour items, nervousness was significantly higher in the ASP group compared to the SRP group (p < 0.0001). Concerning empathy, no differences were found between the SRP and ASP groups. Conclusions Medical students displayed differentiated verbal and non-verbal communication behaviour during the two communication skills training methodologies. These results show that both methodologies have certain advantages and that more explicit non-verbal communication training might be necessary in order to raise students’ awareness for this type of communication and increase doctor-patient interaction effectiveness.

While methods for vehicle modeling are well established for simulation of handling behavior, there is still a lack of driver models, which are important for the realization of closed-loop maneuvers in a virtual environment. This paper will present preliminary considerations for the development of such a driver model. First, trajectory planning strategies have to be generated and evaluated. To achieve this, a method will be deduced, which calculates the maximum velocity at each point of an arbitrary trajectory, taking into account simplified vehicle characteristics in terms of maximum longitudinal and lateral accelerations and considering the frictional ellipse. Thus, the minimum necessary time for each trajectory can be calculated, this being a possible parameter to rate the quality of a trajectory for a given course. The feasibility of the method is demonstrated with the Nuerburgring race track.

As medical students enter the role of physician, clinical outcomes not only rely on their mastery of clinical knowledge, but also on the effectiveness in which they can communicate with patients and family members. While students typically have numerous opportunities to practice clinical communication with adult patients, such practice in pediatric settings is limited. This study examines if simulated patient (SP) encounters strengthen third-year medical students’ communication skills during the pediatrics clerkship. During 2011-2013, three SP encounters (comprising 3 pediatric scenarios) were incorporated into a pediatrics clerkship at one United States medical school to give students a safe venue to practice advanced communication with observation and direct feedback. Third-year medical students engaged in the scenarios and received both written and oral feedback from an evaluator observing the encounter. With IRB approval, students’ self-perceived confidence and abilities at performing the advanced communication skills were measured using an eightitem, Likert scale questionnaire administered pre and post the SP encounter. Pre- and post-questionnaires (n = 215; response rate, 96%) analyzed using a Wilcoxon-matched pairs signed-rank test demonstrated statistically significant increases in students’ perception of their confidence and abilities regarding their performance (P < 0.05; Bonferroni correction, P < 0.006). There was an increases in student confidence and self-perceived ability in: first, communicating with children and family members of young patients; second, managing confrontational situations involving parents; third, performing a thorough psychosocial history with an adolescent; and fourth, using Evidence Based Medicine to motivate parents.

Haptic devices and man-machine interaction have attracted intense research interest in recent years due to numerous potential applications, including medical, dental, military, and nuclear. One of the challenges involved with haptic devices is providing human operator realistic sensory feeling through force feedback output from the haptic device. In order to acquire adequate fidelity, the stiffness of the virtual environment must be sufficiently large. However, this is typically accompanied with vibration of the haptic device. Hence, one of the key issues related to haptic systems is to ensure system’s stability. Although some effort has been done to address this issue, this is so far an unresolved problem. This paper presents current closed-loop PID control method for achieving system stability on the example of one-degree-of-freedom haptic device. In order to identify parameters of the PID controller, the control system is first modeled and the equation of the current closed-loop PID control is formulated. Then, by generalizing the relationship between the motor output torque and the virtual force at the output end of the device, the current closed-loop equation is transferred into that of the force. In addition, the paper analyzes the robustness of PID controlled haptic device. To validate the method, three simulation experiments are performed, with spring model, damper model, and spring damper model. The results show that there is a set of PID parameters which result in stable haptic device. One of the advantages of the proposed method is that it can regulate PID parameters to fit different virtual environment. This provides a fundamental approach to improve stability of haptic systems. In addition, the proposed method can be embedded in the software.
