Background and Objectives: Peripheral nerve blockade requires regional anesthesia skills that trainees learn in several formats. Technical proficiency has shifted from a quota to comprehensive procedural evaluation. Successful nerve blockade is the clinical endpoint validating proficiency but patient, technical and procedural factors influence this result. The purpose of this study was to determine if procedural expertise for sciatic nerve blockade influenced postoperative pain scores and opioid requirements and if patient factors, technique and repetition influenced this outcome. Method: Sciatic nerve blockade by nerve stimulation and ultrasound guidance and training level of the resident performing the procedure were recorded. Patient obesity, trauma, chronic pain, opioid use and preoperative pain scores were compared to post-procedure pain scores and opioid analgesic requirements. Results: 102 patients received sciatic nerve blockade from 47 trainees over a 36 month interval. A significant relation between training level and improved pain scores was not demonstrated but transition from nerve stimulation to ultrasound guidance lowered scores in all groups. Nerve blockade failure was frequent with chronic opioid use and trauma. Conclusion: Analgesic outcomes should be an integral part of assessment of proficiency in regional anesthesia techniques. Evaluating outcomes of procedures throughout training will longitudinally assess technical expertise.

Background: Accessibility is often constructed in terms of physical accessibility. There has been little research into how the environment can accommodate the communicative limitations of people with aphasia. Communication accessibility for people with aphasia is conceptualised in this paper within the World Health Organisation's International Classification of Functioning, Disability and Health (ICF). The focus of accessibility is considered in terms of the relationship between the environment and the person with the disability. Thus: This paper synthesises the results of three Studies that examine the effectiveness of aphasia-friendly written material. Main Contribution: The first study (Rose, Worrall, & McKenna, 2003) found that aphasia-friendly formatting of written health information improves comprehension by people with aphasia, but not everyone prefers aphasia-friendly formatting. Brennan, Worrall, and McKenna (in press) found that the aphasia-friendly strategy of augmenting text with pictures, particularly ClipArt and Internet images, may be distracting rather than helpful. Finally, Egan, Worrall, and Oxenham (2004) found that the use of ail aphasia-friendly written training manual was instrumental in assisting people with aphasia to learn the Internet. Conclusion: Aphasia-friendly formatting appears to improve the accessibility of written material for people with aphasia. Caution is needed when considering the use of illustrations, particularly ClipArt and Internet images, when creating aphasia-friendly materials. A research, practice, and policy agenda for introducing aphasia-friendly formatting is proposed.

Review date: Review period January 1992-December 2001. Final analysis July 2004-January 2005. Background and review context: There has been no rigorous systematic review of the outcomes of early exposure to clinical and community settings in medical education. Objectives of review: (1) Identify published empirical evidence of the effects of early experience in medical education, analyse it, and synthesize conclusions from it. (2) Identify the strengths and limitations of the research effort to date, and identify objectives for future research. Search strategy: Ovid search of. BEI, ERIC, Medline, CIATAHL and EMBASE Additional electronic searches of: Psychinfo, Timelit, EBM reviews, SIGLE, and the Cochrane databases. Hand-searches of: Medical Education, Medical Teacher, Academic Medicine, Teaching and Learning in Medicine, Advances in Health Sciences Education, Journal of Educational Psychology. Criteria: Definitions: Experience: Authentic (real as opposed to simulated) human contact in a social or clinical context that enhances learning of health, illness and/or disease, and the role of the health professional. Early: What would traditionally have been regarded as the preclinical phase, usually the first 2 years. Inclusions: All empirical studies (verifiable, observational data) of early experience in the basic education of health professionals, whatever their design or methodology, including papers not in English. Evidence from other health care professions that could be applied to medicine was included. Exclusions: Not empirical; not early; post-basic; simulated rather than 'authentic' experience. Data collection: Careful validation of selection processes. Coding by two reviewers onto an extensively modified version of the standard BEME coding sheet. Accumulation into an Access database. Secondary coding and synthesis of an interpretation. Headline results: A total of 73 studies met the selection criteria and yielded 277 educational outcomes; 116 of those outcomes (from 38 studies) were rated strong and important enough to include in a narrative synthesis of results; 76% of those outcomes were from descriptive studies and 24% from comparative studies. Early experience motivated and satisfied students of the health professions and helped them acclimatize to clinical environments, develop professionally, interact with patients with more confidence and less stress, develop self-reflection and appraisal skill, and develop a professional identity. It strengthened their learning and made it more real and relevant to clinical practice. It helped students learn about the structure and function of the healthcare system, and about preventive care and the role of health professionals. It supported the learning of both biomedical and behavioural/social sciences and helped students acquire communication and basic clinical skills. There were outcomes for beneficiaries other than students, including teachers, patients, populations, organizations and specialties. Early experience increased recruitment to primary care/rural medical practice, though mainly in US studies which introduced it for that specific purpose as part of a complex intervention. Conclusions: Early experience helps medical students socialize to their chosen profession. It. helps them acquire a range of subject matter and makes their learning more real and relevant. It has potential benefits for other stakeholders, notably teachers and patients. It can influence career choices.

Key events in international politics, such as terrorist attacks, can be characterised as sublime: our minds clash with phenomena that supersede our cognitive abilities, triggering a range of powerful emotions, such as pain, fear and awe. Encounters with the sublime allow us an important glimpse into the contingent and often manipulative nature of representation. For centuries, philosophers have sought to learn from these experiences, but in political practice the ensuing insights are all too quickly suppressed and forgotten. The prevailing tendency is to react to the elements of fear and awe by reimposing control and order. We emphasise an alternative reaction to the sublime, one that explores new moral and political opportunities in the face of disorientation. But we also stress that we do not need to be dislocated by dramatic events to begin to wonder about the world. Moving from the sublime to the subliminal, we explore how it is possible to acquire the same type of insight into questions of representation and contingency by engaging more everyday practices of politics.
