The human patient simulator: acceptance and efficacy as a teaching tool for students. The Medical Readiness Trainer Team

A Description of Breast Models Used to Teach Clinical Skills

Background: Health care trainees lack opportunities to practice breast assessment and clinical skills with patients, making breast models significant for hands-on training. Insufficient training leads to low competence across practitioners in breast health areas of practice, including clinical lactation. The aim of this review was to describe types of breast models used to teach clinical skills of the breast across breast health areas. The secondary aims were to describe education interventions that included each model and identify whether multiple skin tones were available in models. Methods: Authors conducted a scoping review to identify which types of breast models are used to teach clinical skills across breast health areas of practice and determine gaps in literature regarding how clinical lactation skills are taught. The literature search was conducted in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, MedLine, and ProQuest. Inclusion criteria were students/professionals engaging in breast model simulation. Eighteen studies were reviewed. Authors extracted data on participants, breast health area, breast model, intervention, evaluation, general outcomes, skin tone, and research design. Results: The most common skill area was clinical breast exam (n = 7), while least was breastfeeding education (n = 1). Most models were commercial (n = 12). Zero studies described skin tone. Generally, breast model simulations were correlated with increased clinical skills and confidence regardless of model used. Conclusions: Despite demonstrated gain of skills, this review reveals inconsistent use of breast models and evaluation, exclusion of diverse skin tones, and lack of breast models reported to teach clinical lactation skills.

Effects of high-fidelity simulation education on medical students' anxiety and confidence

INTRODUCTION

Psychological factors such as anxiety and confidence that students have in the patient care situation are important in that this affects the actual clinical performance. Students who are just starting clinical practice have a lack of clinical knowledge, skill proficiency, and patient communication skills, so they experience anxiety and lack of confidence in clinical setting. Practice in a safe environment, such as simulation education, can help students perform more settled and competently in patient care. The purpose of this study was to analyze the effect of high-fidelity simulation experience on anxiety and confidence in medical students.

MATERIALS AND METHODS

This study enrolled 37 5th-year students at Ajou University School of Medicine in 2020. Two simulation trainings were implemented, and a survey was conducted to measure students' level of anxiety and confidence before and after each simulation. Based on the research data, a paired t-test was conducted to compare these variables before and after the simulation, and whether this was their first or second simulation experience.

RESULTS

Students had a significantly lower level of anxiety and a significantly higher level of confidence after the simulation than before. In addition, after one simulation experience, students had less anxiety and more confidence before the second simulation compared to those without simulation experience.

CONCLUSIONS

We confirmed that medical students need to be repeatedly exposed to simulation education experiences in order to have a sense of psychological stability and to competently deliver medical treatment in a clinical setting. There is a practical limitation in that medical students do not have enough opportunities to meet the patients during clinical practice in hospitals. Therefore, in order to produce excellent doctors, students should have the expanded opportunities to experience simulation education so they can experience real-world medical conditions.

Case-Based Teaching: Does the Addition of High-Fidelity Simulation Make a Difference in Medical Students' Clinical Reasoning Skills?

CONTEXT

Situativity theory posits that learning and the development of clinical reasoning skills are grounded in context. In case-based teaching, this context comes from recreating the clinical environment, through emulation, as with manikins, or description. In this study, we sought to understand the difference in student clinical reasoning abilities after facilitated patient case scenarios with or without a manikin.

METHODS

Fourth-year medical students in an internship readiness course were randomized into patient case scenarios without manikin (control group) and with manikin (intervention group) for a chest pain session. The control and intervention groups had identical student-led case progression and faculty debriefing objectives. Clinical reasoning skills were assessed after the session using a 64-question script concordance test (SCT). The test was developed and piloted prior to administration. Hospitalist and emergency medicine faculty responses on the test items served as the expert standard for scoring.

RESULTS

Ninety-six students were randomized to case-based sessions with (n = 48) or without (n = 48) manikin. Ninety students completed the SCT (with manikin n = 45, without manikin n = 45). A statistically significant mean difference on test performance between the two groups was found (t = 3.059, df = 88, p = .003), with the manikin group achieving higher SCT scores.

CONCLUSION

Use of a manikin in simulated patient case discussion significantly improves students' clinical reasoning skills, as measured by SCT. These results suggest that using a manikin to simulate a patient scenario situates learning, thereby enhancing skill development.

Computer simulation of the activity of the elderly person living independently in a Health Smart Home

We propose a simulator of human activities collected with presence sensors in our experimental Health Smart Home "Habitat Intelligent pour la Sante (HIS)". We recorded 1492 days of data on several experimental HIS during the French national project "AILISA". On these real data, we built a mathematical model of the behavior of the data series, based on "Hidden Markov Models" (HMM). The model is then played on a computer to produce simulated data series with added flexibility to adjust the parameters in various scenarios. We also tested several methods to measure the similarity between our real and simulated data. Our simulator can produce large data base which can be further used to evaluate the algorithms to raise an alarm in case of loss in autonomy.

Implementation and evaluation of peer assessment of clinical skills for first year student nurses

Enabling student nurses to learn and develop evidence-based clinical skills is the cornerstone of nursing education programmes. This article describes the implementation of a peer assessment scheme for clinical skills within a skills laboratory in a university school of nursing, and the link between peer assessment and clinical skills development. This was a qualitative evaluative study that used questionnaires for data collection and was undertaken on one cohort of students. Findings showed that nearly half of all the statements made by students were about the positive impact of PACS on their skills learning. Students identified giving and receiving peer feedback, reflection and working with peers in small groups as being particularly valuable in clinical skills learning. Increased confidence was also a dominant finding as was the value of repeated practice in a simulation setting on skills development. This study supports some of the previous literature related to use of simulation and peer assessment but the discussion presented in this article also highlights that the findings of this study contradicts other findings in the literature. What makes this study unique is its contribution to the literature is the link that was established by students between the peer-assessment process and clinical skills learning.

A two-year experience of an integrated simulation residency curriculum

BACKGROUND

Human Patient Simulation (HPS) is increasingly used in medical education, but its role in Emergency Medicine (EM) residency education is uncertain.

STUDY OBJECTIVES

The objective of this study was to evaluate the perceived effectiveness of HPS when fully integrated into an EM residency didactic curriculum.

METHODS

The study design was a cross-sectional survey performed in 2006, 2 years after the implementation of an integrated simulation curriculum. Fifty-four residents (postgraduate year [PGY] 1-4) of a 4-year EM residency were surveyed with demographic and curricular questions on the perceived value of simulation relative to other teaching formats. Survey items were rated on a bipolar linear numeric scale of 1 (strongly disagree) to 9 (strongly agree), with 5 being neutral. Data were analyzed using Student t-tests.

RESULTS

Forty residents responded to the survey (74% response rate). The perceived effectiveness of HPS was higher for junior residents than senior residents (8.0 vs. 6.2, respectively, p<0.001). There were no differences in perceived effectiveness of lectures (7.8 vs. 7.9, respectively, p=0.1), morbidity and mortality conference (8.5 vs. 8.7, respectively, p=0.3), and trauma conference (8.4 vs. 8.8, respectively, p=0.2) between junior and senior residents. Scores for perceptions of improvement in residency training (knowledge acquisition and clinical decision-making) after the integration of HPS into the curriculum were positive for all residents.

CONCLUSION

Residents' perceptions of HPS integration into an EM residency curriculum are positive for both improving knowledge acquisition and learning clinical decision-making. HPS was rated as more effective during junior years than senior years, while the perceived efficacy of more traditional educational modalities remained constant throughout residency training.

Using high-fidelity simulation as a teaching strategy with Baby Boomers returning to the RN workforce

As a result of a changing economy, many Baby Boomer nurses are returning to the workforce. Common teaching strategies used in schools of nursing, such as high-fidelity simulation, are unfamiliar to this group of learners. Educators must learn not only the characteristics of Baby Boomer returning nurses but also how to adapt simulation to their learning styles.

A concept analysis of simulation as a learning strategy in the education of undergraduate nursing students

Simulation is increasingly referred to in the nursing literature and its use in healthcare has developed dramatically over the past decade. Whilst the concept of simulation is not new, there is now a greater emphasis on its use in nurse education (Murray et al., 2008). The purpose of this article is to develop understanding and define the concept of simulated learning as a strategy used in the education of undergraduate nursing students. The analysis outlined in this paper was guided by a systematic process of studying a concept presented by Walker and Avant (2005). The analysis sought to identify how the concept of simulation is interpreted in the existing literature printed in English and retrieved from databases (Medline, CINAHL, PubMed, and Cochrane Library), internet search engines (GoogleScholar) and hand searches. The definition offered is a work in progress and presents a theoretically grounded understanding of what simulated learning currently represents. The identified antecedents, critical attributes and consequences are presented as a basis to stimulate further research, development and understanding.

Long-term educational impact of a simulator curriculum on medical student education in an internal medicine clerkship

BACKGROUND

Medical simulation is frequently used in postgraduate medical training, but its value and sustainability in medical student education are less clear. We report the first long-term experience of mannequin simulation in an internal medicine clerkship.

METHODS

During a 6-year period (2002-2009), 327 Harvard medical students participated in a simulator-based teaching experience designed to expose students to the principles of myocardial infarction (MI). This experience was additive to a 12-week clerkship curriculum. Through blinded survey instruments, we sought to determine how the simulator exercise modified student exposure to a core curricular objective in the traditional clerkship. We also sought student and faculty perception of this educational tool and factors important to sustainability.

RESULTS

Three hundred twenty-seven consecutive students were exposed to the simulation exercise and their experiences evaluated. Three hundred twenty-six students (99%) described the simulation experience as valuable, with >69% requesting multiple sessions be provided during each clerkship. Although a core objective, only 78% of students reported having a didactic teaching session on MI during the clerkship, and only 47% of students reported exposure to a live patient with MI. Furthermore, only 15% of students reported exposure to at least two different clinical presentations of MI, allowing comparison and reflection. Thus, the simulation exercise provided the only exposure to this topic for 22% of students and facilitated comparisons of different clinical presentations for 85% of students. When students participated in both the simulator and the didactic sessions, 74% favored the simulation exercise. Faculty cited small group size, once monthly delivery and focused curricula as key points for sustainability of this effort.

CONCLUSION

Mannequin simulation is a valuable and sustainable addition to a third-year internal medicine clerkship. For some students, simulation provides otherwise unavailable exposure to core content material. For the majority of students, simulation also provides the only means of exposure to multiple presentations of a single illness. Together, these data strongly suggest that simulation promotes both experiential learning and comparative analysis in a clerkship setting.

Large group high-fidelity simulation enhances medical student learning

BACKGROUND

Previous work shows feasibility for large group high-fidelity simulation with correlation to basic science in the preclinical curriculum.

AIMS

This project studies whether large group simulation leads to enhanced basic science learning.

METHODS

This was an educational performance study before and after high-fidelity simulation for first-year medical students. Basic neuroscience concepts were reinforced with simulation, and pretesting and posttesting were analysed along with summative exam results. The number correct was compared on a contingency table using the Mantel-Haenszel chi-squared test and same student correlation was accounted for with a 'Generalized Estimating Equations' model.

RESULTS

The study included 112 students; three were excluded for missing data. Students showed statistically significant improvement on two of the four questions, and a nonsignificant improvement or equivalent performance on two questions. Students were significantly more likely to get all four responses correct on the posttest than on the pretest. Summative testing 11 days later had >80% correct responses for three factual recall questions and 58% correct responses for a single knowledge application question.

CONCLUSIONS

Simulation is an effective teaching method for preclinical basic science education. Students demonstrated significant improvements after participating in a live interactive simulation scenario.

A simulation course on lifesaving techniques for third-year medical students

BACKGROUND

The University of Virginia School of Medicine discontinued animal vivisection in February 2004 for teaching lifesaving procedures to third-year medical students. Consequently, a 1-day course using simulation technology was developed to meet objectives previously covered in the animal laboratory. The authors sought to evaluate the course and hypothesized that the students' confidence in lifesaving procedures as well as their acceptance of simulation technology as a teaching tool would increase.

METHODS

The course was designed in a two-session format. The first session (first half of the day) concentrated on individual procedure skills, utilizing part-task trainers. The second session (second half of the day) used a Medical Education Technologies Inc. (METI) Emergency Care Simulator (ECS) full-body patient simulator to present a major trauma scenario. The study design was a prospective, pretest-posttest study without a control group. A 10-question pre and post survey used a Likert scale to explore students' confidence in their skills as well as their acceptance of simulation technology. A course evaluation used a similar Likert scale for evaluation of the course substations, the trauma scenario, and students' self-assessment of their skill levels as well as a 100% point scale for an overall rating of the course.

RESULTS

A total of eight 1-day courses were successfully held over 2 years with a total enrollment of 240 students utilizing 20 instructors inclusive of faculty, residents, and other emergency medicine health care providers. For the pre and post survey results, there was a significant increase in students' confidence in performing lifesaving procedures as well as their acceptance of simulation as a teaching tool (P < 0.05 for each question with pre n = 222 and post n = 226). For the course evaluation results (n = 190), all of the course substations were rated in the good to excellent range and the course received an overall score of 97.55 +/- 7.23% out of 100%. Furthermore, students reported a significant increase in their skill level (P < 0.05).

CONCLUSION

This lifesaving techniques course utilizing simulation technology successfully covered objectives previously taught with animal vivisection, increased students' confidence levels in performing lifesaving procedures and was highly accepted by the medical students.

The effects of human patient simulators on basic knowledge in critical care nursing with undergraduate senior baccalaureate nursing students

BACKGROUND

The nursing literature to date has offered many descriptive accounts utilizing human simulation in undergraduate and graduate nursing curricula. However, the nursing literature remains sparse in the area of studies that evaluate the effectiveness of simulation on knowledge attainment in critical care using standardized assessment tools. The primary aim of this paper is to report on a study that investigates whether participation in instruction involving human patient simulators, in conjunction with a traditional clinical experience, improves professional competence in senior-level undergraduate nursing students related to basic knowledge of critical care nursing.

METHODS

This study (n=29) used a pre- and posttest repeated-measure design. Senior baccalaureate nursing students enrolled in an advanced medical-surgical nursing course participated. Students were assigned to groups and completed 7 weeks of traditional clinical experience (45 hours total) and 7 weeks of high-fidelity human simulation (45 hours total). Students completed the Basic Knowledge Assessment Tool-6 (BKAT-6) prior to traditional clinical and on the last day of human simulation experience.

RESULTS

Results showed a significant improvement on the BKAT-6 overall and a significant improvement in 6 subscales of the BKAT-6.

CONCLUSION

Instruction involving high-fidelity human simulation is a viable teaching strategy to improve basic knowledge acquisition as one essential attribute needed for professional competence.

The fast track back to registered nurses employment

The registered nurse (RN) workforce continues to decline. One method to attract experienced RNs into the workforce is through RN refresher courses. To determine if our RN refresher program is successful in returning RNs to the workforce, we sought to measure the: characteristics of RNs who participate in our program; relationship among participants' employment and demographics; effect of high fidelity human simulation (HFHS) on participants' learning, and; program's ability to meet participants' preparation for employment. Seventy-three participants were surveyed to measure their demographics and employment; they ranked the HFHS experience and program experience on their learning and employment. Thirty-four (47%) surveys were returned. Thirty-three participants (97%) were female (mean age=50.44 years, SD=6.2). Their mean years of RN licensure was 24.93 years (SD=8.8), and their mean time out of nursing practice was 13.30 years (SD=8.0). Twenty-six (76.5%) were employed, with 20 (60.6%) employed as RNs at acute care facilities. Employed participants were licensed for less years than non-employed participants (p=0.047). Employed participants ranked their HFHS experience highly (p=0.04) and the program highly (p=0.04) on benefiting their current employment. Our refresher program appears to be successful in helping RNs re-enter the nursing workforce.

A simulator-based tool that assesses pediatric resident resuscitation competency

BACKGROUND

Competency in pediatric resuscitation is an essential goal of pediatric residency training. Both the exigencies of patient care and the Accreditation Council for Graduate Medical Education require assessment of this competency. Although there are standard courses in pediatric resuscitation, no published, validated assessment tool exists for pediatric resuscitation competency.

OBJECTIVE

The purpose of this work was to develop a simulation-based tool for the assessment of pediatric residents' resuscitation competency and to evaluate the tool's reliability and preliminarily its validity in a pilot study.

METHODS

We developed a 72-question yes-or-no questionnaire, the Tool for Resuscitation Assessment Using Computerized Simulation, representing 4 domains of resuscitation competency: basic resuscitation, airway support, circulation and arrhythmia management, and leadership behavior. We enrolled 25 subjects at each of 5 different training levels who all participated in 3 standardized code scenarios using the Laerdal SimMan universal patient simulator. Performances were videotaped and then reviewed by 2 independent expert raters.

RESULTS

The final version of the tool is presented. The intraclass correlation coefficient between the 2 raters ranged from 0.70 to 0.76 for the 4 domain scores and was 0.80 for the overall summary score. Between the 2 raters, the mean percent exact agreement across items in each domain ranged from 81.0% to 85.1% and averaged 82.1% across all of the items in the tool. Across subject groups, there was a trend toward increasing scores with increased training, which was statistically significant for the airway and summary scores.

CONCLUSIONS

In this pilot study, the Tool for Resuscitation Assessment Using Computerized Simulation demonstrated good interrater reliability within each domain and for summary scores. Performance analysis shows trends toward improvement with increasing years of training, providing preliminary construct validity.

High-Fidelity Simulation and the Development of Clinical Judgment: Students' Experiences

Nursing education programs across the country are making major capital investments in alternative learning strategies, such as human patient simulators; yet, little research exists to affirm this new innovation. At the same time, nursing programs must become even more effective in the development of students' clinical judgment to better prepare graduates to take on increasingly complex care management. This qualitative study examined the experiences of students in one nursing program's first term of using high-fidelity simulation as part of its regular curriculum. On the basis of these experiences, it seems that high-fidelity simulation has potential to support and affect the development of clinical judgment in nursing students and to serve as a value-added adjunct to their clinical practica.

Debriefing in the intensive care unit: a feedback tool to facilitate bedside teaching

OBJECTIVE

To develop an assessment tool for bedside teaching in the intensive care unit (ICU) that provides feedback to residents about their performance compared with clinical best practices.

METHOD

We reviewed the literature on the assessment of resident clinical performance in critical care medicine and summarized the strengths and weaknesses of these assessments. Using debriefing after simulation as a model, we created five checklists for different situations encountered in the ICU--areas that encompass different Accreditation Council for Graduate Medical Education core competencies. Checklists were designed to incorporate clinical best practices as defined by the literature and institutional practices as defined by the critical care professionals working in our ICUs. Checklists were used at the beginning of the rotation to explicitly define our expectations to residents and were used during the rotation after a clinical encounter by the resident and supervising physician to review a resident's performance and to provide feedback to the resident on the accuracy of the resident's self-assessment of his or her performance.

RESULTS

Five "best practice" checklists were developed: central catheter placement, consultation, family discussions, resuscitation of hemorrhagic shock, and resuscitation of septic shock. On average, residents completed 2.6 checklists per rotation. Use of the cards was fairly evenly distributed, with the exception of resuscitation of hemorrhagic shock, which occurs less frequently than the other encounters in the medical ICU. Those who used more debriefing cards had higher fellow and faculty evaluations. Residents felt that debriefing cards were a useful learning tool in the ICU.

CONCLUSIONS

Debriefing sessions using checklists can be successfully implemented in ICU rotations. Checklists can be used to assess both resident performance and consistency of practice with respect to published standards of care in critical care medicine.

A randomized comparison trial of case-based learning versus human patient simulation in medical student education

OBJECTIVES

Human patient simulation (HPS), utilizing computerized, physiologically responding mannequins, has become the latest innovation in medical education. However, no substantive outcome data exist validating the advantage of HPS. The objective of this study was to evaluate the efficacy of simulation training as compared with case-based learning (CBL) among fourth-year medical students as measured by observable behavioral actions.

METHODS

A chest pain curriculum was presented during a one-month mandatory emergency medicine clerkship in 2005. Each month, students were randomized to participate in either the CBL-based or the HPS-based module. All students participated in the same end-of-clerkship chest pain objective structured clinical examination that measured 43 behaviors. Three subscales were computed: history taking, acute coronary syndrome evaluation and management, and cardiac arrest management. Mean total and subscale scores were compared across groups using a multivariate analysis of variance, with significance assessed from Hotelling's T2 statistic.

RESULTS

Students were randomly assigned to CBL (n = 52) or HPS (n = 50) groups. The groups were well balanced after random assignment, with no differences in mean age (26.7 years; range, 22-44 years), gender (male, 52.0%), or emergency medicine preference for specialty training (28.4%). Self-ratings of learning styles were similar overall: 54.9% were visual learners, 7.8% auditory learners, and 37.3% kinetic learners. Results of the multivariate analysis of variance indicated no significant effect (Hotelling's T2 [3,98] = 0.053; p = 0.164) of education modality (CBL or HPS) on any subscale or total score difference in performance.

CONCLUSIONS

HPS training offers no advantage to CBL as measured by medical student performance on a chest pain objective structured clinical examination.

Simulation in medicine: addressing patient safety and improving the interface between healthcare providers and medical technology

Medicine, as an industry in which human lives depend on the skill and performance of operators, must create and maintain a culture of safety, in addition to promoting the design of systems to mitigate errors. The use of medical simulation as a mechanism for training healthcare professionals in a safe environment is expanding rapidly. An important component of systems that ensure the safety of patients in the hospital setting is the interface between humans and technology in the hospital. The objective of this paper is to review: (1) the definition and a brief history of medical simulation, (2) examples of how current medical simulation centers are using simulation to address patient safety, and (3) examples of how simulation can be used to enhance patient safety through improvement of the interface between healthcare practitioners and medical technology. Medical simulation and human factors engineering can be used to examine and enhance the interface between healthcare practitioners and medical technology, with the potential to make a significant contribution to patient safety.

Effectiveness of intermediate-fidelity simulation training technology in undergraduate nursing education

AIM

The aim of this paper is to present the results of a study designed to determine the effect of scenario-based simulation training on nursing students' clinical skills and competence.

BACKGROUND

Using full-scale, realistic, medical simulation for training healthcare professionals is becoming more and more common. Access to this technology is easier than ever before with the opening of several simulation centres throughout the world and the availability on the market of more sophisticated and affordable patient simulators. However, there is little scientific evidence proving that such technology is better than more traditional techniques in the education of, for example, undergraduate nursing students.

METHODS

A pretest/post-test design was employed with volunteer undergraduate students (n = 99) from second year Diploma of Higher Education in Nursing programme in United Kingdom using a 15-station Objective Structured Clinical Examination. Students were randomly allocated to either a control or an experimental group. The experimental group, as well as following their normal curriculum, were exposed to simulation training. Subsequently, all students were re-tested and completed a questionnaire. The data were collected between 2001 and 2003.

RESULTS

The control and experimental groups improved their performance on the second Objective Structured Clinical Examination. Mean test scores, respectively, increased by 7.18 and 14.18 percentage points. The difference between the means was statistically significant (P < 0.001). However, students' perceptions of stress and confidence, measured on a 5-point Likert scale, was very similar between groups at 2.9 (1, not stressful; 5, very stressful) and 3.5 (1, very confident; 5, not confident) for the control group, and 3.0 and 3.4 for the experimental group.

CONCLUSIONS

Intermediate-fidelity simulation is a useful training technique. It enables small groups of students to practise in a safe and controlled environment how to react adequately in a critical patient care situation. This type of training is very valuable to equip students with a minimum of technical and non-technical skills before they use them in practice settings.

A simulator-based curriculum to promote comparative and reflective analysis in an internal medicine clerkship

PURPOSE

To develop and evaluate a novel curricular framework using high-fidelity patient simulation in an internal medicine clerkship.

METHOD

Two 90-minute simulator-based modules of ischemic heart failure and hypoxemic respiratory failure were developed from adult and experiential learning principles. Three short simulated cases focused on each pathophysiologic concept were intermixed with two short teaching sessions and a period of comparative analysis. In 2002-03, the program was piloted among 90 third-year medical students at Harvard Medical School assigned to complete their core internal medicine clerk-ship. An entry and two follow-up questionnaires were used to assess the process. The instructors conducted quantitative and qualitative data analysis and directly observed students' performances.

RESULTS

Instructors consistently noted students' ability to appropriately extract a history, perform a basic examination, and order appropriate tests. However, students demonstrated repeated errors in the application of knowledge to the clinical circumstance. A final comparative discussion was essential to new learning and students recognized this integrative analysis as the most critical component of the exercise. Every student reported the experience as useful. Ninety-four percent (n = 85) felt the simulator should become a routine part of the clerkship and 68% (n = 71) desired three or more sessions during their internal medicine clerkship.

CONCLUSIONS

Simulator-based curricular modules are feasible in an internal medicine clerkship and can successfully complement existing curricula. By comparing similar cases in a compressed time frame, students may achieve enhanced efficiencies in reflective and meta-cognitive learning. As medical simulation is increasingly available, such a curriculum may represent valuable additions to the internal medicine educational environment.

Simulation of patient encounters using a virtual patient in periodontology instruction of dental students: design, usability, and learning effect in history-taking skills

Simulations are important educational tools in the development of health care competence. This study describes a virtual learning environment (VLE) for diagnosis and treatment planning in oral health care. The VLE is a web-based, database application where the learner uses free text communication on the screen to interact with patient data. The VLE contains forms for history taking, clinical images, clinical data and X-rays. After reviewing the patient information, the student proposes therapy and makes prognostic evaluations of the case in free text. A usability test of the application was performed with seven dental students. The usability test showed that the software responded with correct answers to the majority of the free text questions. The application is generic in its basic functions and can be adapted to other dental or medical subject areas. A randomised controlled trial was carried out with 39 students who attended instruction in history taking with problem-based learning cases, lectures and seminars. In addition, 16 of the 39 students were randomly chosen to practise history taking using the virtual patient prior to their first patient encounter. The performance of each student was recorded on video during the patient sessions. The type and order of the questions asked by the student and the degree of empathy displayed towards the patient were analysed systematically on the videos. The data indicate that students who also undertook history taking with a virtual patient asked more relevant questions, spent more time on patient issues, and performed a more complete history interview compared with students who had only undergone standard teaching. The students who had worked with the virtual patient also seemed to have more empathy for the patients than the students who had not. The practising of history taking with a virtual patient appears to improve the capability of dental students to take a relevant oral health history.

"Practicing" medicine without risk: students' and educators' responses to high-fidelity patient simulation

PURPOSE

To understand the responses of medical students and educators to high-fidelity patient simulation, a new technology allowing "practice without risk."

METHOD

Pilot groups of students (n = 27) and educators (n = 33) were exposed to a simulator session, then surveyed with multiple-choice and open-ended questions. Open-ended comments were transcribed and coded. They were analyzed for recurring themes and tested for inter-rater agreement. An independent focus group subsequently performed higher-level thematic analysis.

RESULTS

Overall, 85% of the students rated the session excellent and 85% of the educators rated it excellent or very good. Over 80% of both groups thought that simulator-based training should be required for all medical students. Analytic categories derived from written comments were: Overall Assessment (i.e., "generally good experience"); Process Descriptors (i.e., "very realistic"); Teaching Utility (i.e., "broad educational tool"); Pedagogic Efficacy (i.e., "promotes critical thinking"); and Goals for Future Use (i.e., "more practice sessions"). Thirty percent of students and 38% of educators were impressed by the realism of the simulator, and they (37% and 25%, respectively) identified the ability to "practice" medicine as the primary advantage of simulation. The focus group rated cost as the major current disadvantage (66%).

CONCLUSIONS

Students' and educators' responses to high-fidelity patient simulation were very positive. The ability to practice without risk must be weighed against the cost of this new technology.
