Assessment in undergraduate psychiatric education

An assessment of medical students' psychiatric performance demonstrated no association between the ability to rate psychopathology or to observe interview behaviour and traditional written methods of academic achievement. This is in accordance with those few studies which have addressed this issue and indicates that there may well be at least three independent skills involved in clinical decision-making: the ability to engage in interpersonal interaction and elicit information; and the ability to acquire and use academic knowledge. This is consistent with work suggesting that maturational and learning processes influence clinical reasoning, and demonstrates that each component should be addressed in assessing students in psychiatry.     

Attitudes of the 1984 medical graduates of Sri Lanka to anaesthesia

A total of 196 intern medical officers who had graduated from the four medical schools in Sri Lanka in 1984 indicated their attitudes towards anaesthesia as a medical specialty in response to a postal questionnaire. Eighty per cent of the graduates considered anaesthesia to be an established specialty in Sri Lanka, while 17% felt that the specialty had limited clinical application. A total of 62% of the graduates were not aware, prior to their entry to medical school, that anaesthesia was related to medical practice. All the graduates indicated that the intra-operative role of the anaesthetist was on a par with that of the surgeon, but 40% felt that the pre- and post-operative roles were of a secondary nature. Overall, 42% considered that an anaesthetist acts as an assistant to the surgeon. The graduates were of the opinion that only 35% of the patients undergoing surgery were appreciative of the services rendered by an anaesthetist. Fifty per cent of the graduates considered exposure to the specialty in the undergraduate curriculum as inadequate. Anaesthesia was chosen as the first career preference by 1.5%. The dominant reasons for not selecting anaesthesia as a career specialty were: minimal patient contact and patient recognition (62%), and lack of recognition of the specialty by society (54%). Anaesthetists in Sri Lanka are challenged to alter the perceptions associated with the specialty, which are probably a result of chronic staff shortages restricting practice to the confines of operating theatres.     

Integrating human factors into the medical curriculum

Background  The study of human factors is a scientific discipline that deals with the interactions between human beings and the elements of a system. This is important because shortcomings in these areas, if unchecked, can result in adverse outcomes. Research into human factors in industries where safety is paramount has provided the basis of countermeasures against human error. Adverse outcomes in medicine resulting from human error exact a high cost in both patient suffering and financial outlay.
CRM training  One of the approaches used to minimise the effect of human error is to train people in a set of knowledge, skills and attitudes that underpin the domain-specific competencies for that profession. These are referred to as non-technical skills (NTS). In aviation, such an approach has been shown to be both translatable from the training environment to the workplace and effective in reducing adverse outcomes.
Discussion  Medicine has incorporated this style of training, usually centred around simulator-based courses, but as yet in a piecemeal, episodic fashion which relies on participants volunteering to attend courses. Unlike other industries there is no systematic approach to linking the content of this teaching with the more conventional range of topics. As a consequence it is difficult to assess the impact of human factors training in medicine. This is partly because very little work has been done to date in identifying the key non-technical skills required in medicine, and the overall experience of workplace based assessment is limited. Lessons from other high reliability organisations may help to address the main challenges of developing the content, integrating it into the curriculum, reinforcing the concepts in the workplace through staff development and establishing its role in summative assessment.

卵圆孔未闭动物模型的建立

目的 探讨采用正常中华小型猪制作卵圆孔未闭动物模型的可行性。方法 中华小型猪11只，选取1只行预实验，10只用于正式实验。全身麻醉下，经股静脉送入Rups-100穿刺针系统，在透视引导下穿刺房间隔卵圆窝，然后对穿刺点行球囊扩张术。预实验动物术后1d处死，正式实验组动物术后21d处死。心脏取材，行病理检查。结果 11只猪均成功行房间隔穿刺和球囊扩张术，并经心房造影证实建立卵圆孔未闭模型。正式实验组动物除1只术中出现心包积液外，其余术中及术后均无并发症。预实验动物于处死后肉眼观房间隔卵圆窝有-0．7cm×0．8cm缺损，光学显微镜下见红细胞聚集。正式实验组动物于处死后观察，7只可见房间隔卵圆窝愈合，3只分别残留0．1cm×0．2cm、0．2cm×0．2cm、0．1cm×0．3cm缺损。正式实验组动物无论卵圆窝是否愈合，光学显微镜下在穿刺点周围均可见不同程度的局灶性心内膜增生和缺失、淋巴细胞聚集、心肌细胞肿胀、坏死和间质纤维化。结论 采用房间隔穿刺和球囊扩张的方法，用中华小型猪建立卵圆孔未闭模型是可行的。     

Teachers'' perceptions concerning the relative values of personal and clinical characteristics and their influence on the assignment of students'' clinical grades

Twenty senior teachers were asked to rank, in order of influence, the seven clinical and five personal characteristics used to grade third-year medicine clerks. Seventeen perceived themselves to be more influenced by clinical characteristics when assigning grades. Independently, the actual ratings completed over a 3-year period by these same teachers were analysed to measure the congruency between their perceived and actual grading behaviour. When actually rating students only nine raters were more influenced by clinical characteristics and just one half of the teachers displayed a congruency between their perceived and actual rating behaviour. The implications of these findings are discussed.     

Medical education for minorities at a US medical school

The University of Washington School of Medicine (UWSM) has initiated new efforts to build a regional minority applicant pool and to expand its educational programmes to accommodate students from disadvantaged backgrounds. Specific interventions include: establishment of medical career planner position to coordinate region-wide outreach; pre-entry education; and support activities once enrolled. This study describes specific services and presents sociodemographic and performance data on 56 minority and 280 majority students entering the UWSM between 1981 and 1985. Economic status and educational background of minority students were significantly below that of majority students, several flexible academic policies enabled most students to achieve mastery in courses and to progress through the curriculum. The educational data base utilized in this study, and those at other institutions, can assume important roles in the identification of problem areas in the education of disadvantaged students and in evaluation of the interventions attempted.     

Choosing a career in general practice: the influence of medical schools

Summary. This paper reviews the literature on career choice to investigate the undergraduate influences on the preference of Australian graduates for a career in general practice. Although isolation of influencing factors is difficult, admission criteria and undergraduate curricula may influence career preference. As the institutional environment of medical schools is weighted towards scientific research and specialized medicine, medical students may be socialized into choosing non-generalist careers. Medical schools should consider broadening selection criteria and curriculum exposure to produce graduates with a broad range of career interests.     

Detection of HLA-A*24 null alleles by DNA typing methods

Abstract: A number of cases have been identified (seven unrelated individuals from the Northern Ireland bone marrow donor registry and two family groups) where an HLA-A*24 allele fails to express the normal HLA-A24 antigen. Family information has revealed common haplotypes with respect to each non-expressed allele indicating that the occurrence of these mutations has been a recent event. Two methods for the clinical typing of these alleles have been evaluated - PCR-SSOP and PCR-SSCP analysis.     

House officers in general medicine: their perception of educational value of rotation components

Summary: As curriculum planners in general medicine residency training programmes we were concerned about house officers' anecdotal reports that hospital work requirements often overshadow individual learning goals. After each of five rotations, we asked residents to identify the educational 'usefulness' of certain rotation components which can be included in three categories; team members, work-related activities and educational events. Of 165 surveys distributed, 127 (77%) were returned. Data were analysed by residency year and by all years combined. The mean overall perception of learning was 3.9 out of a possible 5 points suggesting that residents do find some learning value. Results suggest that different residency years vary as to the significance of specific educational components. The importance of faculty/resident relationships to residents' perceptions of learning value was highlighted in particular.
