Development of a Simulation-Based Mastery Learning Curriculum for Breaking Bad News

Introduction

Physician communication impacts patient outcomes. However, communication skills, especially around difficult conversations, remain suboptimal, and there is no clear way to determine the validity of entrustment decisions. The aims of this study were to 1) describe the development of a simulation-based mastery learning (SBML) curriculum for breaking bad news (BBN) conversation skills and 2) set a defensible minimum passing standard (MPS) to ensure uniform skill acquisition among learners.

血管介入仿真模拟器在心血管医生冠状动脉介入技术规范化培训中的作用

目的明确Angiomemor（美国Simbionix公司生产）血管介入仿真模拟器是否有助于冠状动脉造影技术的掌握和提高。方法选取16名无血管放射介入经验的心血管医生，接受相同课时的冠状动脉介入造影理论培训后，按随机表编码随机分为模拟器培训组与非培训组各8名，模拟器培训组8名医生接受Angiomemor血管介入仿真模拟器培训，模拟冠状动脉造影操作，非培训组8名心血管医生未接受仿真模拟器培训。在随后的真实临床环境中操作冠状动脉造影时，评价2组医生冠状动脉造影操作过程中错误的频数、平均造影时间、造影剂使用量及术中放射线剂量。结果相对于非培训组，模拟器培训组医生在冠状动脉造影操作中错误频数减少62．5％、平均造影时间减少44．0％、造影剂使用量减少44．0％，术中平均放射线曝光时间减少了57．7％，平均X线累计曝光剂量减少51．6％，单位面积X线累计曝光剂量减少了52．4％。结论Angiomemor血管介入仿真模拟器有助于医生较快地熟练掌握冠状动脉造影技术，是冠状动脉介入规范化培训的重要辅助手段之一。     

Preference awareness education as stress management training for academic staff

This paper describes a response directed stress management intervention (SMI) in the form of a Jungian based preference awareness education (PAE). It uses the Insights System of personality types to increase awareness of behaviour and communication preferences of self and different others. Eighteen self‐recruited academic employees participated for 7 weeks and received feedback about work preferences and personality type. The aim was to reduce perceptions of stress and interpersonal stress and to increase feelings of job satisfaction and interpersonal satisfaction. The data were analysed using two‐tailed t‐tests. No significant findings were observed for the total sample after training, however, interesting results were found for certain sub‐sample groups. Extravert‐thinking types, reported decreased stress levels (p > 0.018), and participants suffering high stress/interpersonal stress pre‐PAE, reported decreased stress levels (p > 0.010–0.018). Participants suffering low job/interpersonal satisfaction pre‐PAE, reported increased job satisfaction (p > 0.015–0.016). These results suggest that individuals who report high levels of stress and dissatisfaction are most likely to benefit from this type of intervention. Future PAE research might: (a) use pilot studies to meet the intervention preferences of employees that are reluctant to participate in SMIs; (b) include a wait‐list control group; use: (c) a follow up education/measures; (d) and organizational level (stressor directed) SMIs at the same time as response directed initiatives.

The development and evaluation of Student Training, Education and Practice for Dietetics CD-ROM: a computer-assisted instruction programme for dietetic students

The Student Training, Education and Practice for Dietetics (STEP‐DIET) CD‐ROM was developed at the University of Surrey to prepare dietetic students for the practical dietetic training component of their Nutrition/Dietetics degree. This study aimed to evaluate student response to the programme and its effectiveness as a teaching tool, based on the evaluation framework of D.L. Kirkpatrick (Evaluating a Course, 2nd edn. London, Kogan Page). Quantitative and qualitative methodologies were employed, with 41 dietetic students, separated by year group, completing questionnaires and taking part in six focus groups, at the University of Surrey. Student attitudes towards the instruction method and the STEP‐DIET programme itself were investigated, in conjunction with their perceived learning achievements. Students rated the programme highly in terms of design and content, however, there was a reluctance to accept computer‐assisted instruction (CAI) as a sole teaching method. A number of learning achievements relevant to dietetic practice were reported including a perceived increase in ability to conduct a dietetic interview and an increased understanding of the management of Type 2 diabetes. In general students reacted positively to the STEP‐DIET programme and it was perceived by students to be effective in preparing them for the practical component of their dietetic training.     

Recognition and management of patients with high-risk vesicovaginal fistulas: Implications for teaching and research

Vesicovaginal fistulas (VVFs) occurring as a result of obstetric trauma are a vast problem in Nigeria and Ghana, where at least 20 000 women await repair, and fewer than 50 physicians have the necessary expertise. Through a series of conferences those VVFs that are at high risk and those at low-risk for repair failure, were identified. A clinic was established where repair of low-risk VVFs was done on an ongoing basis in a remote region of Ghana. A visiting surgical team was utilized to repair the difficult, or high-risk, VVFs, which included 4–6 cm VVFs (3), recurrent VVF (1), combined VVF and RVF (rectovaginal fistula), a large 5 cm juxtacervical VVF (1), and a vesicouterine fistula (1). Management of these patients and others with VVF repair complications is discussed.     

Skeletal Muscle Adaptations to Physical Training in Type II (Non-insulin-dependent) Diabetes Mellitus

Seven middle-aged men with manifest type II diabetes mellitus underwent an endurance training programme for 10–15 weeks. The maximal aerobic capacity, as well as the endurance capacity, was improved by 10% (p<0.05). The intramuscular glycogen store increased by more than 80% (p<0.05) from 350 μmol/g dw (dry weight), and the activities of citrate synthase and 3-hydroxy-acyl-CoA dehydrogenase increased by more than 50% (p<0.05) and 30% (p<0.05). The activity of glycogen synthase was decreased by approximately 20% (p<0.05), whereas lactate dehydrogenase remained unchanged. Capillaries/fibre and fibre area increased by more than 50% (p<0.05) and 30% (p<0.05) leaving the area of supply constant. Training did not influence fasting blood lipids and glucose, glycosylated hemoglobin, oral glucose tolerance, and insulin response to an oral glucose load measured 72 hours post-exercise. It is concluded that patients with manifest type II diabetes, as normoglycaemic individuals, adapt to physical training. However, no persistent effect on glucohomeostasis and lipaemia is produced by short-term training in the diabetic patients.     

Short utterance recognition using a network with minimum training

A feedforward network is used to recognize short, digitized, isolated utterances. A high, multispeaker recognition rate is achieved with a small vocabulary with a single training utterance. This approach makes use of the pattern recognition property of the network architecture to classify different temporal patterns in the multidimensional feature space. The network recognizes the utterances without the need of segmentation, phoneme identification, or time alignment. We train the network with four words spoken by one single speaker. The network is then able to recognize 20 tokens spoken by 5 other speakers. We repeat the above training and testing procedure using a different speaker's utterances for training each time. The overall accuracy is 97.5%. We compare this approach to the traditional dynamic programming (DP) approach, and find that DP with slope constraints of 0 and 1 achieve 98.5% and 85% accuracies respectively. Finally we validate out statistics by training and testing the network of a four-word subset of the Texas Instruments (Tl) isolated word database. The accuracy with this vocabulary exceeds 96%. By doubling the size of the training set, the accuracy is raised to 98%. Using a suitable threshold, we are able to raise the accuracy of one network from 87% to 98.5%. Thresholding applied to all networks would then raise the overall accuracy to well over 99%.

This technique is especially promising because of the low overhead and computational requirements, which make it suitable for a low cost, portable, command recognition type of application.     

Development of the Diploma in Clinical Dentistry (Conscious Sedation and Pain Control) Faculty of Dentistry, University of Sydney

The Diploma in Clinical Dentistry (Conscious Sedation and Pain Control) of the Faculty of Dentistry, University of Sydney, is the first dedicated programme devoted to this field in Australia. Its development followed a decision by the Dental Board of New South Wales to require a formal qualification from the University of Sydney before dental practitioners could offer sedation and pain management in practice.
The programme is conducted at Westmead Hospital in conjunction with the Department of Anaesthetics, and satisfies the guidelines developed by the Royal Australasian College of Dental Surgeons and the Royal Australasian College of Surgeons.
The course is conducted either over one or two years, with block sessions requiring attendance at Westmead Hospital, together with assignments which are completed outside the block sessions. In this way, a dental practitioner enrolled in the programme is able to continue practice.
The block sessions need not be completed over one year, but must be completed within two years.
