What works for and what hinders deimplementation of low-value care in emergency medicine practice? A scoping review.

OBJECTIVES: Low-value care can harm patients and healthcare systems. Despite a decade of global endeavours, low value care has persisted. Identification of barriers and enablers is essential for effective deimplementation of low-value care. This scoping review is an evidence summary of barriers, enablers and features of effective interventions for deimplementation of low-value care in emergency medicine practice worldwide. DESIGN: A mixed-methods scoping review was conducted using the Arksey and O'Malley framework. DATA SOURCES: Medline, CINAHL, Embase, EMCare, Scopus and grey literature were searched from inception to 5 December 2022. ELIGIBILITY CRITERIA: Primary studies which employed qualitative, quantitative or mixed-methods approaches to explore deimplementation of low-value care in an EM setting and reported barriers, enablers or interventions were included. Reviews, protocols, perspectives, comments, opinions, editorials, letters to editors, news articles, books, chapters, policies, guidelines and animal studies were excluded. No language limits were applied. DATA EXTRACTION AND SYNTHESIS: Study selection, data collection and quality assessment were performed by two independent reviewers. Barriers, enablers and interventions were mapped to the domains of the Theoretical Domains Framework. The Mixed Methods Appraisal Tool was used for quality assessment. RESULTS: The search yielded 167 studies. A majority were quantitative studies (90%, 150/167) that evaluated interventions (86%, 143/167). Limited provider abilities, diagnostic uncertainty, lack of provider insight, time constraints, fear of litigation, and patient expectations were the key barriers. Enablers included leadership commitment, provider engagement, provider training, performance feedback to providers and shared decision-making with patients. Interventions included one or more of the following facets: education, stakeholder engagement, audit and feedback, clinical decision support, nudge, clinical champions and training. Multifaceted interventions were more likely to be effective than single-faceted interventions. Effectiveness of multifaceted interventions was influenced by fidelity of the intervention facets. Use of behavioural change theories such as the Theoretical Domains Framework in the published studies appeared to enhance the effectiveness of interventions to deimplement low-value care. CONCLUSION: High-fidelity, multifaceted interventions that incorporated education, stakeholder engagement, audit/feedback and clinical decision support, were administered daily and lasted longer than 1 year were most effective in achieving deimplementation of low-value care in emergency departments. This review contributes the best available evidence to date, but further rigorous, theory-informed, qualitative and mixed-methods studies are needed to supplement the growing body of evidence to effectively deimplement low-value care in emergency medicine practice.

Cultural safety in telehealth consultations with Indigenous people: A scoping review of global literature.

INTRODUCTION: Telehealth has become increasingly routine within healthcare and has potential to reduce barriers to care, including for Indigenous populations. However, it is crucial for practitioners to first ensure that their telehealth practice is culturally safe. This review aims to describe the attributes of culturally safe telehealth consultations for Indigenous people as well as strategies that could promote cultural safety. METHODS: A scoping review was conducted on key features of cultural safety in telehealth for Indigenous people using the Johanna Briggs Institute (JBI) guidelines and PRISMA-ScR checklist. Five electronic databases were searched, and additional literature was identified through handsearching. RESULTS: A total of 649 articles were screened resulting in 17 articles included in the review. The central themes related to the provision of culturally safe telehealth refer to attributes of the practitioner: cultural and community knowledge, communication skills and the building and maintenance of patient-provider relationships. These practitioner attributes are modified and shaped by external environmental factors: technology, the availability of support staff and the telehealth setting. DISCUSSION: This review identified practitioner-led features which enhance cultural safety but also recognised the structural factors that can contribute, both positively and negatively, to the cultural safety of a telehealth interaction. For some individuals, telehealth is not a comfortable or acceptable form of care. However, if strategies are undertaken to make telehealth more culturally safe, it has the potential to increase opportunities for access to care and thus contribute towards reducing health inequalities faced by Indigenous peoples.

Trace elements in ambient aerosols and size-resolved fog droplets: Trends, enrichment, and risk assessment.

Ambient particulate matter (PM) is composed of inorganic and organic components. The contribution of each component is impacted by various factors such as emission sources, atmospheric aging process, and size of the PM or droplets. This study mainly focuses on the effect of the PM and droplet size on trace elemental concentrations, for which various size fractions of ambient PM (PM1, PM2.5) were collected on quartz filters along with fog water (FW) samples during winter. Simultaneous, online measurements of the mass concentrations of PM1 and PM2.5 were also carried out. At the time of the collection, the mass concentration of PM2.5 ranged from 19 to 890 µg/m3, and its mean value was 227 µg/m3. During the sampling period, 17 fog events occurred and caused a 27% reduction in the mean pre-fog PM2.5 concentration. All the PM and FW samples were analyzed for 12 trace elements: Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Zn, V. The concentrations of the various trace elements in the PM1, PM2.5, and FW samples encompassed a wide range: 10 (V)-2432 (Na) ng/m3, 34 (Mn)-13810 (Na) ng/m3, and 8 (Cr)-19870 (Ca) µg/l, respectively. The concentrations of the trace elements in the FW samples indicated a droplet-size-dependent trend: the small droplets (diameter <16 µm) had several times (3-10 times) higher concentrations than the coarser droplets (diameter >22 µm). The enrichment factor (EF) analysis revealed that the EF values for almost all the trace elements were an order of magnitude higher in the FW samples than in PM1 and PM2.5. Risk assessment based on toxic elements suggested a very high inhalation carcinogenic risk (231 per million) for the exposed population during foggy periods. This study will facilitate decision-making by policymakers regarding air quality and health concerns.

Wintertime aerosol properties of urban desert region of western India: Implications in regional climate assessment.

This study assessed the inter-relation between physiochemical and optical characteristics of aerosols measured at a desert-urban region affected by anthropogenic sources and desert dust during October 2020 to January 2021. Based on horizontal visibility and measured PM2.5 concentration, clear (37 %), light (33 %) and high (31 %) pollution periods were identified. Elemental and organic carbon (50 ± 15 µgm-3; 31 %) and secondary inorganics (53 ± 21 µgm-3; 33 %) dominated the PM2.5 mass (160 ± 4 µgm-3) during high pollution period with low dust (14 ± 7 µgm-3; 8 %) content. Interestingly, the clear pollution period was also influenced by carbonaceous fraction (19 ± 8 µgm-3; 32 %) and secondary inorganics (19 ± 5 µgm-3; 32 %), but the PM2.5 concentrations (59 ± 9 µgm-3) were ∼ one-third as compared to high pollution period. High scattering coefficients were observed which were comparable to highly polluted Indian city like Delhi. An exponential increase in non-absorbing material was observed and showed clear influence on light absorption capacity of EC and dust due to coating/mixing. High absorption Ångström exponent (AAE) >0.6 was observed for the ratio of non-absorbing to light absorbing components (LAC) in the range of 1-2.5 and EC/PM2.5 fraction of 7-14 %. While further increase in non-absorbing to absorbing components ratio > 4 and low amount of EC (<4 %) tend to decrease AAE below 0.4. Higher mass absorption cross-section (>30 m2g-1 of EC) was observed when 4-10 % EC fraction of PM2.5 associated with 1.5-3.5 times non-absorbing components to total absorbing components. Likewise, absorption enhanced by three to five folds compared to uncoated EC for low EC fraction (3-6 %) in PM2.5, but high non-absorbing to absorbing component ratio (>2.5). Interestingly, absorption was minimally amplified for nominal coating fraction associated with significant core materials or vice-versa. These findings have implications not only in regional climate assessment but also for other regions with comparable geography and source-mixes.

Identification of barriers, enablers and interventions to inform deimplementation of low-value care in emergency medicine practice: A protocol for a mixed methods scoping review informed by the Theoretical Domains Framework.

INTRODUCTION: Low-value care can lead to patient harm, misdirected clinician time and wastage of finite healthcare resources. Despite worldwide endeavours, deimplementing low-value care has proved challenging. Multifaceted, context and barrier-specific interventions are essential for successful deimplementation. The aim of this literature review is to summarise the evidence about barriers to, enablers of and interventions for deimplementation of low-value care in emergency medicine practice. METHODS AND ANALYSIS: A mixed methods scoping review using the Arksey and O'Malley framework will be conducted. MEDLINE, CINAHL, EMBASE, EMCare, Scopus and grey literature will be searched from inception. Primary studies will be included. Barriers, enablers and interventions will be mapped to the domains of the Theoretical Domains Framework. Study selection, data collection and quality assessment will be performed by two independent reviewers. NVivo software will be used for qualitative data analysis. Mixed Methods Appraisal Tool will be used for quality assessment. Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews framework will be used to present results. ETHICS AND DISSEMINATION: Ethics approval is not required for this scoping review. This review will generate an evidence summary regarding barriers to, enablers of and interventions for deimplementation of low-value care in emergency medicine practice. This review will facilitate discussions about deimplementation with relevant stakeholders including healthcare providers, consumers and managers. These discussions are expected to inform the design and conduct of planned future projects to identify context-specific barriers and enablers then codesign, implement and evaluate barrier-specific interventions.

Assessment of cultural safety in a post-Objective Structured Clinical Examination (OSCE) era.

BACKGROUND: As The Royal Australian College of General Practitioners (RACGP) introduces alternatives to the Objective Structured Clinical Examination, it is imperative that standards are continually set for a culturally safe general practice workforce. Assessments have many functions and should be continually reviewed to ensure that they require general practitioners (GPs) to demonstrate genuine cultural safety. OBJECTIVE: The aim of this article is to highlight the complexities in assessing the cultural safety of GPs when consulting with Aboriginal and Torres Strait Islander peoples. DISCUSSION: Presently there is a lack of validated approaches for assessing cultural safety of GPs. This creates challenges for the RACGP in redesigning fellowship examinations. Yet in this challenge is an opportunity to consider assessment design that is not competency based, amplifies Aboriginal and Torres Strait Islander peoples' voices and reflects the complexity of cultural safety.

Systematic review of specialist selection methods with implications for diversity in the medical workforce.

PURPOSE: There is growing concern that inequities in methods of selection into medical specialties reduce specialist cohort diversity, particularly where measures designed for another purpose are adapted for specialist selection, prioritising reliability over validity. This review examined how empirical measures affect the diversity of specialist selection. The goals were to summarise the groups for which evidence is available, evaluate evidence that measures prioritising reliability over validity contribute to under-representation, and identify novel measures or processes that address under-representation, in order to make recommendations on selection into medical specialties and research required to support diversity. METHOD: In 2020-1, the authors implemented a comprehensive search strategy across 4 electronic databases (Medline, PsychINFO, Scopus, ERIC) covering years 2000-2020, supplemented with hand-search of key journals and reference lists from identified studies. Articles were screened using explicit inclusion and exclusion criteria designed to focus on empirical measures used in medical specialty selection decisions. RESULTS: Thirty-five articles were included from 1344 retrieved from databases and hand-searches. In order of prevalence these papers addressed the under-representation of women (21/35), international medical graduates (10/35), and race/ethnicity (9/35). Apart from well-powered studies of selection into general practice training in the UK, the literature was exploratory, retrospective, and relied upon convenience samples with limited follow-up. There was preliminary evidence that bias in the measures used for selection into training might contribute to under-representation of some groups. CONCLUSIONS: The review did not find convincing evidence that measures prioritising reliability drive under-representation of some groups in medical specialties, although this may be due to limited power analyses. In addition, the review did not identify novel specialist selection methods likely to improve diversity. Nevertheless, significant and divergent efforts are being made to promote the evolution of selection processes that draw on all the diverse qualities required for specialist practice serving diverse populations. More rigorous prospective research across different national frameworks will be needed to clarify whether eliminating or reducing the weighting of reliable pre-selection academic results in selection decisions will increase or decrease diversity, and whether drawing on a broader range of assessments can achieve both reliable and socially desirable outcomes.

Leadership curricula and assessment in Australian and New Zealand medical schools.

BACKGROUND: The Australian Medical Council, which accredits Australian medical schools, recommends medical leadership graduate outcomes be taught, assessed and accredited. In Australia and New Zealand (Australasia) there is a significant research gap and no national consensus on how to educate, assess, and evaluate leadership skills in medical professional entry degree/programs. This study aims to investigate the current curricula, assessment and evaluation of medical leadership in Australasian medical degrees, with particular focus on the roles and responsibilities of medical leadership teachers, frameworks used and competencies taught, methods of delivery, and barriers to teaching leadership. METHODS: A self-administered cross-sectional survey was distributed to senior academics and/or heads or Deans of Australasian medical schools. Data for closed questions and ordinal data of each Likert scale response were described via frequency analysis. Content analysis was undertaken on free text responses and coded manually. RESULTS: Sixteen of the 22 eligible (73%) medical degrees completed the full survey and 100% of those indicate that leadership is taught in their degree. In most degrees (11, 69%) leadership is taught as a common theme integrated throughout the curricula across several subjects. There is a variety of leadership competencies taught, with strengths being communication (100%), evidence based practice (100%), critical reflective practice (94%), self-management (81%), ethical decision making (81%), critical thinking and decision making (81%). Major gaps in teaching were financial management (20%), strategic planning (31%) and workforce planning (31%). The teaching methods used to deliver medical leadership within the curricula are diverse, with many degrees providing opportunities for leadership teaching for students outside the curricula. Most degrees (10, 59%) assess the leadership education, with one-third (6, 35%) evaluating it. CONCLUSIONS: Medical leadership competencies are taught in most degrees, but key leadership competencies are not being taught and there appears to be no continuous quality improvement process for leadership education. There is much more we can do as medical educators, academics and leaders to shape professional development of academics to teach medical leadership, and to agree on required leadership skills set for our students so they can proactively shape the future of the health care system.

"We learnt it, then we lived it": Influencing medical students' intentions toward rural practice and generalist careers via a socially-accountable curriculum.

OBJECTIVE: The James Cook University (JCU) medical school has a mission to produce graduates committed to practising with underserved populations. This study explores the views of final-year students regarding the influence of the JCU medical curriculum on their self-reported commitment to socially-accountable practice, intentions for rural practice, and desired postgraduate training pathway. METHODS: Cross-sectional survey of final year JCU medical students (n = 113; response rate = 65%) to determine whether their future career directions (intentions for future practice rurality and postgraduate specialty training pathway) are driven more by altruism (commitment to socially accountable practice/community service) or by financial reward and/or prestige. RESULTS: Overall, 96% of responding students reported their JCU medical course experiences had cultivated a greater commitment towards 'socially-accountable' practice. A commitment to socially-accountable practice over financial reward and/or prestige was also significantly associated with preferring to practise Medicine in non-metropolitan areas (p = 0.036) and intending to choose a 'generalist' medical discipline (p = 0.003). CONCLUSIONS: The findings suggest the JCU medical curriculum has positively influenced the commitment of its graduating students towards more socially accountable practice. This influence is a likely result of pre-clinical teachings around health inequalities and socially-accountable medical practice in combination with real-world, immersive experiences on rural and international placements.

'Stability' of Assessment: Extending the Utility Equation.

This article was migrated. The article was marked as recommended. The COVID-19 pandemic has brought many challenges to medical education, necessitating a rapid transition to digital delivery. The widespread move to online exams has introduced novel risks, including the risk of catastrophic IT failure. These are not 'black swan' events - something so unexpected and devastating that we could not anticipate them and prepare accordingly. The phrase 'black elephants', a cross between a black swan and 'the elephant in the room' has been coined to describe these events. Moving to high-stakes online examinations introduces another element that needs to be considered and managed: the 'stability' of the assessment format used. This dimension incorporates notions of 'platform reliability' and 'internal risk management' and can be caused by both unplanned events eg IT failures, and planned events like security breaches Developing approaches to mitigate this new risk suggests another dimension to the well-known assessment 'utility equation': stability of the platform used. This paper explores the concept of stability from the perspectives of educational institutions and candidates and offers some approaches to achieving stability. The delivery of assessment in the digital age, requires the 'utility equation' to be recalibrated and establishment of a new "sweet spot" for each assessment program.

How does GP training impact rural and remote underserved communities? Exploring community and professional perceptions.

BACKGROUND: Substantial government funding has been invested to support the training of General Practitioners (GPs) in Australia to serve rural communities. However, there is little data on the impact of this expanded training on smaller communities, particularly for smaller rural and more remote communities. Improved understanding of the impact of training on underserved communities will assist in addressing this gap and inform ongoing investment by governments and communities. METHOD: A purposive sample of GP supervisors, GP registrars, practice managers and health services staff, and community members (n = 40) from previously identified areas of workforce need in rural and remote North-West Queensland were recruited for this qualitative study. Participants had lived in their communities for periods ranging from a few months to 63 years (Median = 12 years). Semi-structured interviews and a focus group were conducted to explore how establishing GP training placements impacts underserved communities from a health workforce, health outcomes, economic and social perspective. The data were then analysed using thematic analysis. RESULTS: Participants reported they perceived GP training to improve communities' health services and health status (accessibility, continuity of care, GP workforce, health status, quality of health care and sustainable health care), some social factors (community connectedness and relationships), cultural factors (values and identity), financial factors (economy and employment) and education (rural pathway). Further, benefits to the registrars (breadth of training, community-specific knowledge, quality of training, and relationships with the community) were reported that also contributed to community development. CONCLUSION: GP training and supervision is possible in smaller and more remote underserved communities and is perceived positively. Training GP registrars in smaller, more remote communities, matches their training more closely with the comprehensive primary care services needed by these communities.

Immune checkpoint inhibitor-related colitis assessment and prognosis: can IBD scoring point the way?

BACKGROUND: Immune checkpoint inhibitors (ICI) improve survival but cause immune-related adverse events (irAE). We sought to determine if CTCAE classification, IBD biomarkers/endoscopic/histological scores correlate with irAE colitis outcomes. METHODS: A dual-centre retrospective study was performed on patients receiving ICI for melanoma, NSCLC or urothelial cancer from 2012 to 2018. Demographics, clinical data, endoscopies (reanalysed using Mayo/Ulcerative Colitis Endoscopic Index of Severity (UCEIS) scores), histology (scored with Nancy Index) and treatment outcomes were analysed. RESULTS: In all, 1074 patients were analysed. Twelve percent (134) developed irAE colitis. Median patient age was 66, 59% were male. CTCAE diarrhoea grade does not correlate with steroid/ infliximab use. G3/4 colitis patients are more likely to need infliximab (p < 0.0001) but colitis grade does not correlate with steroid duration. CRP, albumin and haemoglobin do not correlate with severity. The UCEIS (p = 0.008) and Mayo (p = 0.016) scores correlate with severity/infliximab requirement. Patients with higher Nancy indices (3/4) are more likely to require infliximab (p = 0.03). CONCLUSIONS: CTCAE assessment does not accurately reflect colitis severity and our data do not support its use in isolation, as this may negatively impact timely management. Our data support utilising endoscopic scoring for patients with >grade 1 CTCAE disease, and demonstrate the potential prognostic utility of objective histologic scoring.

Twelve tips for OSCE-style Tele-assessment.

This article was migrated. The article was marked as recommended. The Australian College of Rural and Remote Medicine (ACRRM) has developed a flexible 'tele-assessment' approach to the delivery of its assessment modalities. Candidates can sit their examination remotely, close to their place of practice, which reduces the need for rural doctors - both candidates and examiners - to leave their communities for the purpose of assessment. A major component of the assessment process is the Structured Assessment using Multiple Patient Scenarios (StAMPS) examination, which blends the formats of an Objective Structured Clinical Examination (OSCE) and a traditional viva vocè examination. It is a high-stakes assessment, that was designed to be academically rigorous, flexible, valid, reliable, and fair. Since 2008 ACRRM has provided a videoconferencing option to candidates for their StAMPS examination allowing them to remain in or near their home location, while the examiners meet a central location. Travel restrictions due to the SARS-CoV-2 pandemic meant for the first time both candidates AND examiners participated in StAMPS via videoconference. ACRRM conducted an online StAMPS assessment using videoconferencing technology for 65 candidates in mid-May 2020, with all candidates, examiners and support staff remaining in or near their home communities. These Twelve Tips outline some of the experience gained in providing tele-assessment over the past twelve years.

Fellowship of the Australian College of Rural & Remote Medicine (FACRRM) Assessment: a review of the first 12 years.

This article was migrated. The article was marked as recommended. This paper provides an overview of the first 12 years of the formal assessment program of the Australian College of Rural and Remote Medicine (ACRRM). The ACRRM Fellowship represents the world's first and only Fellowship exam in Rural Medicine. The ACRRM assessment program is mapped to its Rural Generalist curriculum, based on the principles of programmatic assessment. ACRRM offers candidates the opportunity to participate in assessment in or close to their home location. The ACRRM Rural Generalist Curriculum defines the scope and standards for independent general practice anywhere in Australia, with a focus on rural and remote settings. The program was initially developed in 2006 and has evolved during delivery from 2008 onwards, utilising the following modalities: •Multi Source Feedback (MSF)•Multiple Choice Questions (MCQ)•Mini Clinical Evaluation Exercise (Mini-CEX)•Case Based Discussion (CBD)•Procedural Skills Logbook•Structured Assessment using Multiple Patient Scenarios (StAMPS) StAMPS is a unique examination, blending the formats of an Objective Structured Clinical Examination and a traditional viva vocè. The program has an emphasis on formative assessment. Over the past 12 years there has been considerable work in developing resources for candidates, governance structures and quality assurance processes. ACRRM's Fellowship requirements represent a customised bespoke assessment tailored to ACRRM's curriculum and the Australian rural and remote context. ACRRM's assessment program has grown substantially with 649 Fellowships being awarded from 2008 - 2019, with considerable experience gained in rural and remote assessment. It now represents a mature firmly-established process as a vocational endpoint in Rural and Remote Medicine. ACRRM has continued to offer its 'tele-assessment' program throughout the COVID-19 pandemic, with candidates and examiners participating in assessment by use of distance technology while remaining in or near their home community. This model may provide some insights for other medical Colleges and educational institutions facing challenges in the current environment.

International approaches to rural generalist medicine: a scoping review.

BACKGROUND: Contemporary approaches to rural generalist medicine training and models of care are developing internationally as part of an integrated response to common challenges faced by rural and remote health services and policymakers (addressing health inequities, workforce shortages, service sustainability concerns). The aim of this study was to review the literature relevant to rural generalist medicine. METHODS: A scoping review was undertaken to answer the broad question 'What is documented on rural generalist medicine?' Literature from January 1988 to April 2017 was searched and, after final eligibility filtering (according to established inclusion and exclusion criteria), 102 articles in English language were included for final analysis. RESULTS: Included papers were analysed and categorised by geographic region, study design and subject themes. The majority of articles (80%) came from Australia/New Zealand and North America, reflecting the relative maturity of programmes supporting rural generalist medicine in those countries. The most common publication type was descriptive opinion pieces (37%), highlighting both a need and an opportunity to undertake and publish more systematic research in this area. Important themes emerging from the review were: Definition Existing pathways and programmes Scope of practice and service models Enablers and barriers to recruitment and retention Reform recommendations There were some variations to, or criticisms of, the definition of rural generalist medicine as applied to this review, although this was only true of a small number of included articles. Across remaining themes, there were many similarities and consistent approaches to rural generalist medicine between countries, with some variations reflecting environmental context and programme maturity. This review identified recent literature from countries with emerging interest in rural generalist medicine in response to problematic rural health service delivery. CONCLUSIONS: Supported, coordinated rural generalist medicine programmes are being established or developed in a number of countries as part of an integrated response to rural health and workforce concerns. Findings of this review highlight an opportunity to better share the development and evaluation of best practice models in rural generalist medicine.

Developing a general practice workforce for the future.

BACKGROUND: Australia continues to develop as a multicultural nation, with a population that is ageing and developing complex health needs. The world around us is changing, and the pace of change is increasing. These contextual changes pose challenges for general practice training. OBJECTIVE: This paper explores the potential impact of these changes on the general practice workforce. DISCUSSION: General practitioners (GPs) will continue to have a central role in coordinating continuous, comprehensive care but are more likely to act as managers of multi-source, continuous monitoring data that facilitate personalised medical care. GPs will need to adapt rapidly to change, seizing opportunities offered by disruptive technology in a globalised world affected by climate change. The nature and impact of change is difficult to predict, and more research is needed to explore how change will affect healthcare and healthcare professionals. Ideally, training for general practice should include preparation for managing continuous change.

Assessment for learning: a needs analysis study using formative assessment to evaluate the need for curriculum reform in basic sciences.

A needs analysis study for curriculum reform in basic sciences was conducted at Melaka Manipal Medical College, India, by means of a formative assessment method, namely Basic Science Retention Examination (BSRE). Students participated in a BSRE, which comprised recall and clinical multiple-choice questions in six discipline areas. They also rated the clinical relevance of each question and provided responses to three open-text questions about the exam. Pass rates were determined; clinical relevance ratings and performance scores were compared between recall type and clinical questions to test students' level of clinical application of basic science knowledge. Text comments were thematically analyzed to identify recurring themes. Only one-third of students passed the BSRE (32.2%). Students performed better in recall questions compared with clinical questions in anatomy (51.0 vs. 40.2%), pathology (45.1 vs. 38.1%), pharmacology (41.8 vs. 31.7%), and biochemistry (43.5 vs. 26.9%). In physiology, students performed better in clinical questions compared with the recall type (56.2 vs. 45.8%). Students' response to BSRE was positive. The findings imply that transfer of basic science knowledge was poor, and that assessment methods should emphasize clinical application of basic science knowledge.

Chemical characterization and quantitativ e assessment of source-specific health risk of trace metals in PM1.0 at a road site of Delhi, India.

This study presents the concentration of submicron aerosol (PM1.0) collected during November, 2009 to March, 2010 at two road sites near the Indian Institute of Technology Delhi campus. In winter, PM1.0 composed 83% of PM2.5 indicating the dominance of combustion activity-generated particles. Principal component analysis (PCA) proved secondary aerosol formation as a dominant process in enhancing aerosol concentration at a receptor site along with biomass burning, vehicle exhaust, road dust, engine and tire tear wear, and secondary ammonia. The non-carcinogenic and excess cancer risk for adults and children were estimated for trace element data set available for road site and at elevated site from another parallel work. The decrease in average hazard quotient (HQ) for children and adults was estimated in following order: Mn > Cr > Ni > Pb > Zn > Cu both at road and elevated site. For children, the mean HQs were observed in safe level for Cu, Ni, Zn, and Pb; however, values exceeded safe limit for Cr and Mn at road site. The average highest hazard index values for children and adults were estimated as 22 and 10, respectively, for road site and 7 and 3 for elevated site. The road site average excess cancer risk (ECR) risk of Cr and Ni was close to tolerable limit (10-4) for adults and it was 13-16 times higher than the safe limit (10-6) for children. The ECR of Ni for adults and children was 102 and 14 times higher at road site compared to elevated site. Overall, the observed ECR values far exceed the acceptable level.

The Ethics of Medical Practitioner Migration From Low-Resourced Countries to the Developed World: A Call for Action by Health Systems and Individual Doctors.

Medical migration appears to be an increasing global phenomenon, with complex contributing factors. Although it is acknowledged that such movements are inevitable, given the current globalized economy, the movement of health professionals from their country of training raises questions about equity of access and quality of care. Concerns arise if migration occurs from low- and middle-income countries (LMICs) to high-income countries (HICs). The actions of HICs receiving medical practitioners from LMICs are examined through the global justice theories of John Rawls and Immanuel Kant. These theories were initially proposed by Pogge (1988) and Tan (1997) and, in this work, are extended to the issue of medical migration. Global justice theories propose that instead of looking at health needs and workforce issues within their national boundaries, HICs should be guided by principles of justice relevant to the needs of health systems on a global scale. Issues of individual justice are also considered within the framework of rights and social responsibilities of individual medical practitioners. Local and international policy changes are suggested based on both global justice theories and the ideals of individual justice.
