Assessment and evaluation of work-related musculoskeletal disorders among nuclear medicine professionals in India: A cross-sectional study.

BACKGROUND: Musculoskeletal disorders (MSDs) are a severe occupational health issue among medical radiation practitioners. It is mostly linked to personal protective wear, working posture, tools employed and ergonomics. OBJECTIVE: To assess and evaluate the musculoskeletal disorders among nuclear medicine professionals (NMP) in India. METHODS: An online survey was distributed to 455 NMP throughout India between November 2021 and March 2022 covering the demographic characteristics and questions for evaluation of musculoskeletal symptoms using the Standardized Nordic Musculoskeletal Questionnaire (NMQ). Participants with any pre-existing musculoskeletal disorder or trauma were excluded. Descriptive statistics summarized the data from the demographics, discomfort, aches and work-related musculoskeletal injuries. Chi-square test was used to examine the association between the obtained values. RESULTS: 91 out of 124 respondents were included based on the inclusion and exclusion criteria. Results shows that there is a significant association between the height of the individual and neck pain, body mass index and elbows pain, age and low back pain, experience in the current work and upper back pain, the weight of the individual and knee pain, use of mobile lead screens and shoulder pain, use of gonad shield, trouble in the ankles and use of lead screens, and QC phantoms for gamma camera / PET and wrists/hands pain. CONCLUSION: Work-related musculoskeletal disorders among NMP are resulting from factors of individual demographic variables (such as age, height, weight, body mass index), years of experience at the current workplace and of using instruments in their work area.

Zoonotic infections in UK and Irish veterinary students: a cross-sectional survey.

BACKGROUND: Zoonotic infections are a recognised risk for the veterinary community. Veterinary students are at risk, due to the range of activities they participate with on training coupled with their inexperience; yet the prevalence and severity of infections in veterinary students has been little studied. In this study, a survey explored zoonotic infections in UK and Irish veterinary students. METHODS: A survey containing both open and closed questions, was distributed to undergraduate veterinary students at all veterinary schools in the UK and Republic of Ireland. Descriptive statistics, and univariable logistic regression were used to explore quantitative data; thematic analysis was used to explore qualitative data. RESULTS: There were 467 responses, 31.5% (95% CI 27.3-35.9, n = 147) of those students reported having contracted at least one zoonotic infection during their studies. The most prevalent self-reported infections were cryptosporidiosis (15.2% of all respondents), dermatophytosis (5.6%), and other gastrointestinal infections assumed to be of zoonotic origin (4.5%). 7% of respondents reported having acquired a zoonosis within the last 12 months, 91% of these infections were acquired during farm placements. Thematic analysis (n = 34) showed that infection was an accepted risk, particularly on farm, and students were often reluctant to take time off their studies or placements as a result of infection. Reporting was very low, meaning universities would not have accurate figures on infection risk or particularly risky placement providers. CONCLUSIONS: Based on these survey results, veterinary students appear to be at increased risk of contracting zoonotic diseases, particularly on farm placements. Attitude and behaviour change at multiple levels is required to reduce the risk of infection to students and normalise reporting of illness.

A bibliometric analysis of remote working practices: Call for future research.

BACKGROUND: According to Gallup survey report, 69% of U.S. workers moved to working remotely in April 2020. Due to COVID-19, work is changing rapidly, including where individuals work. OBJECTIVE: Research in this field has drawn much attention, and in the last ten years, there is a constant augment in the number of publications on the same. Several works of literature on Remote Working (RW) culture have been reported. Nevertheless, only less research is present on bibliometric reviews of RW culture. Therefore, Bibliometric research is wielded in this work and a comprehensive review of relevant publications was taken from Scopus, Web of Science (WOS), together with the Social Science Citation Index Expanded. METHODOLOGY: At first, meticulous bibliometric analyses of 430 published articles are done and descriptive information about a piece of work, namely (a) author, (b) title, (c) date of publication, et cetera, is provided. RESULTS: Mapping the scope along with the structure of the discipline is enabled by these analyzes, which discovers the instituted collaboration patterns amongst countries and organizations, and identifies authoritative papers together with authors. Therefore, the publication's evolution over time is illustrated by these analyses, and the current research interests and potential directions for future study are identified. CONCLUSIONS: This paper incorporates insights on remote working culture and enables mapping the scope and structure of the discipline, discovering the established collaboration patterns among countries and organizations. Thus, these analyses illustrate the publication's evolution over time and identified the current research interests and potential directions for the research.

Establishing a health-based recommended occupational exposure limit for isoflurane using experimental animal data: a systematic review protocol.

BACKGROUND: Isoflurane is used as an inhalation anesthetic in medical, paramedical, and veterinary practice. Epidemiological studies suggest an increased risk of miscarriages and malformations at birth related to maternal exposure to isoflurane and other inhalation anesthetics. However, these studies cannot be used to derive an occupational exposure level (OEL), because exposure was not determined quantitatively and other risk factors such as co-exposures to other inhalation anesthetics and other work-related factors may also have contributed to the observed adverse outcomes. The aim of this systematic review project is to assess all available evidence on the effects of isoflurane in studies of controlled exposures in laboratory animals to derive a health-based recommended OEL. METHODS: A comprehensive search strategy was developed to retrieve all animal studies addressing isoflurane exposure from PubMed, EMBASE, and Web of Science. Title-abstract screening will be performed by machine learning, and full-text screening by one reviewer. Discrepancies will be resolved by discussion. We will include primary research in healthy, sexually mature (non human) vertebrates of single exposure to isoflurane. Studies describing combined exposure and treatments with > = 1 vol% isoflurane will be excluded. Subsequently, details regarding study identification, study design, animal model, and intervention will be summarized. All relevant exposure characteristics and outcomes will be extracted. The risk of bias will be assessed by two independent reviewers using an adapted version of the SYRCLE's risk of bias tool and an addition of the OHAT tool. For all outcomes for which dose-response curves can be derived, the benchmark dose (BMD) approach will be used to establish a point of departure for deriving a recommended health-based recommended OEL for 8 h (workshift exposure) and for 15 min (short-term exposure). DISCUSSION: Included studies should be sufficiently sensitive to detect the adverse health outcomes of interest. Uncertainties in the extrapolation from animals to humans will be addressed using assessment factor. These factors are justified in accordance with current practice in chemical risk assessment. A panel of experts will be involved to reach consensus decisions regarding significant steps in this project, such as determination of the critical effects and how to extrapolate from animals to humans.

Sexual and Sexist Violence in the Universities of Southern Spain.

Situations of sexual and sexist harassment are the result of daily and widespread practices that also occur in universities. This study aims to investigate experienced and perceived situations of sexual and sexist violence in universities in southern Spain. The methodology consists of a review of the literature and the production of primary data using the quantitative method and the questionnaire technique. The sample consisted of 1,583 members of the university community of one of the ten universities in southern Spain, with a total population of 23,500 people. The results, in terms of harassment experienced (real or technical), reveal that the main victims of sexual and sexist harassment in the universities of southern Spain are women and people with different sexual identities (more than 83% of cases), between 19 and 50 years, and belonging to the student, teaching and research staff, and administration and services staff, without a permanent position. Female students are the most vulnerable, while men, in any of the categories, are victims in less than 17% of cases. Likewise, in 86% of the cases the harasser is a male, while women are harassers in 10.5% of the cases and people with diverse sexual identity are harassers in 3.5% of the situations. With regard to perceived (declared) harassment, the study concludes that the sex of the people surveyed, their level of studies, the university campus to which they belong and gender stereotypes are determining factors in the degree of perception of harassment situations. On the other hand, age, status, and employment status do not play a significant role in the respondents' perceptions.

A Resident-as-Leader Curriculum for Managing Inpatient Teams.

PROBLEM: Leading inpatient teams is a foundational clinical responsibility of resident physicians and leadership is a core competency for inpatient physicians, yet few training programs have formal leadership curricula to realize this clinical skill. INTERVENTION: We implemented a 4-module curriculum for PGY1 internal medicine residents. The program focused on the managerial skills necessary for daily clinical leadership, followed by clinical coaching. Interns were first introduced to foundational concepts and then given the opportunity to apply those concepts to real-world practice followed by clinical coaching. CONTEXT: Using direct-observations and a previously published checklist for rounds leadership, this study sought to evaluate the workplace behavior change for novice residents leading inpatient teams for the first time. We conducted a prospective cohort study (March 2016 and August 2018) of internal medicine residents at a large tertiary academic medical center in Boston, MA. Trained faculty raters performed direct observations of clinical rounding experiences using the checklist and compared the findings to historical and internal controls. Questionnaires were distributed pre- and post- curriculum to assess satisfaction and readiness to lead a team. IMPACT: We trained 65 PGY1 residents and raters conducted 140 direct observations - 36 in the intervention group and 104 among historical controls. The unadjusted mean score in rounds leadership skills for the intervention group was 19.0 (SD = 5.1) compared to 16.2 (SD = 6.2) for historical controls. Adjusting for repeated measures, we found significant improvement in mean scores for behaviors linked to the curricular objectives (p = 0.008) but not for general behaviors not covered by the curriculum (p = 0.2). LESSONS LEARNED: A formal curriculum to train residents as leaders led to behavior change in the workplace in domains essential to rounds leadership. We also found that the curriculum was highly regarded in that all interns indicated they would recommend the curriculum to a peer. Moreover, the program may have assuaged some anxiety during the transition to junior year as 90% of interns surveyed felt more ready to start PGY2 year than historical trainings. We learned that while a robust, multi-faceted modular curriculum and clinical coaching successfully resulted in behavior change, the resources required to manage this program are significant and difficult to sustain. Future iterations could include asynchronous material and potentially peer-observation of rounds leadership to reduce the burden on faculty and program curricular time.

Faculty-or senior resident-led SNAPPS for postgraduate teaching in pediatrics.

This was an educational intervention on postgraduates using SNAPPS (Summarize narrow, analyze, probe, plan, self-directed learning) showing comparable median (interquartile range) satisfaction scores with faculty or senior residents as 4 (3,5) and 4 (4, 4.25); respectively, P = 0.79. Further training of senior residents in medical education will enable them to participate efficiently and actively in postgraduate teaching.

A New Instrument for Assessing Work-Related Body Mechanics and Strain in the General Population.

Clinical pain is often linked to poor body mechanics, with individuals sometimes presenting multiple painful disorders. Such disorders may be influenced by behaviors that affect the general resiliency and health of the musculoskeletal system. We aimed to develop a self-reported scale using the Malmö Diet and Cancer Study questions on work-related body mechanical exposures. An expert panel identified 41 variables having content validity for musculoskeletal problems. Exploratory factor analysis was conducted on a random selection of 50% of the cohort (n = 6,789 adults); the remaining was reserved for confirmatory factor analyses (CFA), item response theory (IRT) item calibration, and differential item functioning investigations. Supported by standard measure development methods and fit criteria, the final unidimensional item bank contains 13 items. Overall CFA statistics (root mean square error of approximation = .09; comparative fit index = .96; Tucker-Lewis index = .96; standardized root mean residuals = .05) indicated excellent single-factor model fit and appropriateness of IRT modeling and calibration. Expert review and item information values (score-precision) guided selection of an 8-item short form with acceptable score-level reliabilities (≥.70) for T-scores = 39-80+. This measure provides reliable assessment of body mechanics strain in adults and can be useful when evaluating different contributions to musculoskeletal problems affecting pain-treatment success in future clinical research. PERSPECTIVE: This article presents the development and psychometric properties of a new measure, "Work-related Body Mechanics and Strain Scale (WR-BMSS)." The scale has 13-items or alternatively an 8-item short form. This measure could potentially help clinicians who seek to assess how musculoskeletal problems may contribute to patient pain and disability.

EPMO: A novel medical student assessment tool that integrates entrustable professional activities, prime, and the modified Ottawa coactivity scale.

PURPOSE: Alignment of workplace-based assessments (WPBA) with core entrustable professional activities (EPAs) for entering residency may provide opportunities to monitor student progress across the continuum of undergraduate medical education. Core EPAs, however, reflect tasks of varying degrees of difficulty and faculty assessors are not accustomed to rating students based on entrustability. Expectations of student progress should vary depending on the complexity of the tasks associated with the EPAs. An assessment tool that orients evaluators to the developmental progression of specific EPA tasks will be critical to fairly evaluate learners. METHODS: The authors developed an EPA assessment tool combining the frameworks of Professionalism, Reporter, Interpreter, Manager, Educator (PRIME), and Modified Ottawa coactivity scales. Only those EPAs that could be repeatedly observed and assessed across clinical clerkships were included. From July 2019 to March 2020, third-year medical students across multiple clerkships were assessed using this tool. The authors hypothesized that if the tool was applied correctly, ratings of learner independence would be lower with higher complexity tasks and that such ratings would increase over the course of year with ongoing clinical learning. RESULTS: Assessment data for 247 medical students were similar across clerkships suggesting that evaluators in diverse clinical contexts were able to use this tool to assign scores reflective of developing entrustability in the workplace. Faculty rated student entrustability highest in skills emphasized in the pre-clerkship curriculum (professionalism and reporter) and progressively lower in more advanced skills (interpreter and manager). Students' ratings increased over time with more clinical exposure. CONCLUSIONS: The authors developed a composite WBPA tool that combines the frameworks of EPAs, PRIME, and Modified Ottawa Co- Activity and demonstrated the usability of applying it for learner assessments in clinical settings. Further multicenter studies with cohorts of pre- and post-clerkship students may provide additional validity evidence for the tool.

Protocol for a scoping review of work system design in health care.

BACKGROUND: Delivery of safe and reliable healthcare to patients and the healthcare workforce shortage amidst growing demand has been major challenge to the healthcare system. Addressing this challenge calls for designing or redesigning of healthcare work system. Work system design which is usually associated with productivity in manufacturing offers a wide spectrum of applicability in addressing this challenge of healthcare system. Despite the availability of primary studies on work system design in healthcare, there are sparse published reviews in specific contexts. This scoping review explores the existing evidence to understand the state of the art of work system design in healthcare. METHODS: The scoping review adopts the methodology of Joanna Briggs Institute for scoping review which is based on the methodological framework of Arksey and O'Malley. The search will be done on PubMed, Scopus, and Web of Science for the identification of eligible studies. A grey literature search will also be performed. A two-phase screening and extraction of data will be done by two independent reviewers. Data extraction will be done on a pre-piloted data extraction form. The findings will be presented in tables, figures, and a narrative summary. The scoping review will highlight the state of the art, gaps in knowledge and provide directions for future research. ETHICS AND DISSEMINATION: This is a scoping review of primary studies and therefore ethical approval is not required. The report of the findings will be presented in line with the PRISMA reporting guidelines for scoping reviews (PRISMA-ScR). The results will be submitted to a peer-reviewed scientific journal for publication and presented at relevant conferences.

Changing trends in assessment: Effectiveness of Direct observation of procedural skills (DOPS) as an assessment tool in anesthesiology postgraduate students.

Background and Aims: National Medical commission of India (NMC) has introduced Competency based Medical Education (CBME) following the international trend. Competency based assessment differs from traditional assessment and we need to adopt to newer work place-based assessments (WPBA). Direct Observation of Procedural Skills (DOPS) is one such assessment tool, which assesses procedural skills of a student. Hence this study was conducted to evaluate the effectiveness of DOPS among Anesthesiology postgraduate students. Material and Methods: A prospective interventional study was conducted, where in 55 postgraduate students underwent DOPS assessment while performing three routine core skills of Anesthesiology. Observations were documented (Pre-DOPS-Score) and immediate verbal feedback was given. Students were educated through demonstration of all three procedures on actual patients by three faculty members using the DOPS checklist. The students were finally assessed again with proforma and DOPS scores were documented (Post-DOPS Score). Mean Pre-DOPS and Post-DOPS assessment Scores were compared. Student and faculty Perceptions were taken regarding the DOPS assessment. Results: There was significant improvement in the procedural skill performance after DOPS with a statistically significant difference. Average time taken for DOPS test was 11 min. Average time taken for giving feedback was 13 min. Students and faculty members gave positive feedback about DOPS. Conclusion: DOPS is very feasible and effective assessment tool, improves procedural skills of Anaesthesiology postgraduate students, helps to develop good clinical skills which finally brings good clinical care.

Revisión sistemática con análisis de sesgo y calidad de intervenciones en el ambiente alimentario del lugar de trabajo y su impacto en el estado nutricional de los trabajadores / Systematic review with analysis of bias and quality of interventions in the food environment of the workplace and their impact on the nutritional status of workers

Introducción: la exposición de los trabajadores a una alimentación no saludable tiene relación con el aumento del sobrepeso y la obesidad. Objetivo: esta revisión sistemática tiene como objetivo analizar con análisis de sesgo y calidad el efecto de las intervenciones en el ambiente alimentario del lugar de trabajo en el estado nutricional de los trabajadores. Métodos: la búsqueda se realizó en tres bases de datos electrónicas de acuerdo a Colaboración Cochrane y fueron incluidos ocho estudios. Los datos se agruparon según tipo de intervención ambiental, se analizó la calidad metodológica y se evaluó la validez con el riesgo de sesgo. Resultados: de los ocho estudios, tres tuvieron efectos en la reducción del índice de masa corporal (IMC) y peso corporal, pero uno fue considerado como evidencia confiable de efectividad por tener bajo riesgo de sesgo. La mitad de los artículos incluidos fueron evaluados con alto riesgo de sesgo (3/8) y riesgo de sesgo poco claro (1/8) por errores en la selección y la realización y datos faltantes en los resultados. Conclusiones: se concluye que no hay suficiente evidencia para indicar que este tipo de intervenciones tienen efecto sobre el peso corporal. Para realizar intervenciones efectivas, el diseño de estos estudios tiene que evitar las fuentes potenciales de sesgo, que fueron analizadas en detalle en este estudio. Se debe considerar el entorno alimentario global de los trabajadores y no solo su lugar de trabajo, profundizando la interacción que existe entre factores socioeconómicos y ambientes alimentarios.

Introduction: workers' exposure to unhealthy eating is linked to the increase in overweight and obesity. Objective: this systematic review aims to analyze with bias and quality analysis the effect of interventions in the food environment of the workplace on the nutritional status of workers. Methods: the search was conducted in three electronic databases according to the Cochrane Collaboration and eight studies were included. Data were grouped according to type of environmental intervention, and methodological quality and validity with risk of bias was analyzed. Results: three studies had effects on reducing BMI and body weight, but one was judged to be reliable evidence of effectiveness, as they were at low risk of bias. Half of the included articles were assessed at high risk of bias (3/8) and unclear risk of bias (1/8), due to errors in selection and performance and missing data in the results. Conclusions: we conclude that there is not enough evidence to indicate that these types of interventions have an effect on body weight. To make effective interventions, the design of these studies has to avoid potential sources of bias, which were analyzed in detail in this study. The global food environment of workers and not just their workplace must be considered, deepening the interaction that exists between socioeconomic factors and food environments. (AU)

Seroprevalence of SARS-CoV-2 Infection Among Working Women and Impact of Workplace Restrictions.

Objective: To determine the prevalence of SARS-CoV-2 virus infection among female workers who were restricted to working from home compared with those who continued to attend in-person work. Methods: As part of national surveillance program, serum samples for SARS-CoV-2 antibody testing and nasopharyngeal swabs for SARS-CoV-2 PCR were obtained on 1636 female school staff and salon/spa workers who were restricted to work remotely (restricted group) and 1190 female health-care workers who continued in-person work (unrestricted group). Results: Seropositivity rate was 5.1% among the restricted and 22.7% among the unrestricted group (P < 0.0001). Presence of symptoms at baseline (adjusted odds ratio [aOR], 2.88; 95% CI 2.09-3.97), contact with a confirmed case (aOR 2.34; 95% CI 1.37-3.98), and unrestricted work type (aOR 4.71; 95% CI 3.24-6.86) were associated with a higher risk of infection, while increasing age was associated with a lower risk of infection. Conclusion: Prevalence of SARS-CoV-2 infection as determined by seropositivity was higher among women who were not subject to workplace restrictions.

Letalidad por desplazamientos domicilio-trabajo-domicilio en el Ecuador, 2014-2019 y 2020 / Home-workplace-home commuting lethality in Ecuador, 2014-2019 and 2020

Objetivo: Evidenciar las diferencias de letalidad según lugar de ocurrencia (desplazamientos = in itínere y en jornada laboral) en el periodo entre 2014 a 2019 y 2020 en el Ecuador. Material y Métodos: Análisis de 104.396 casos (1,2% mortales) utilizando registros oficiales. Se estimaron Tasas de Letalidad (TL) y Razón de Tasas de Letalidad (RTL) por lugar de ocurrencia y separadas por sexo. Resultados: Las TL y RTL mostraron descensos importantes. Sin embargo, las probabilidades de fallecimiento in itínere fueron mayores en comparación a los accidentes mortales ocurridos en jornada laboral, de forma global [1,51 (IC95% = 1,13-2,04); p = 0,006], en hombres, [1,58 (IC95% = 1,38-1,82); p = 0,000] y, en específico, en mujeres, [5,93 (IC95% = 1,86-16,34); p = 0,001]. Conclusiones: Se deberían realizar estudios epidemiológicos específicos y prestar mayor interés a este problema de seguridad vial laboral en el diseño de estrategias de salud pública y laboral. (AU)

Objective: To demonstrate the differences in fatality rates by place of occurrence (commuting = in itínere and during working hours) in the period from 2014 to 2019 and 2020 in Ecuador. Material and Methods: Analysis of 104,396 cases (1.2% fatal) using official records. Lethality Rates (LR) and Lethality Rate Ratio (LRR) were estimated by place of occurrence and separated by sex. Results: LR and LRR showed significant decreases. However, the odds of in itínere fatalities were higher in comparison to work-related fatalities, overall [1.51 (95%CI = 1.13-2.04); p = 0.006], in men, [1.58 (95%CI = 1.38-1.82); p = 0.000] and specifically in women, [5.93 (95%CI = 1.86-16.34); p = 0.001]. Conclusions: Specific epidemiological studies should be carried out and more interest should be given to this occupational road safety problem in the design of public and occupational health strategies.

Workplace Mental Health Interventions in India: A Rapid Systematic Scoping Review.

The mental health initiatives at the workplace are growing in numbers over the past few years. Public and private sectors continue to explore avenues to navigate and adapt initiatives to promote employee's mental wellbeing. However, such initiatives in the Indian context are not thoroughly studied. We attempted to review existing literature on workplace mental health interventions in the Indian context. The scoping review was conducted following the standard process as recommended by the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Review and Meta-Analysis extension for scoping reviews. We searched in the databases such as PubMed, Google Scholar and Scopus. Scientific literature including gray literature of the past decade was searched to synthesize evidence on types of mental health interventions and their unique features. Of the 1,311 records, 30 records that met the inclusion criteria were included for the final review. The review highlights evidence on stress and mental health problems faced by the working population and various strategies adopted by organizations to address mental health problems. However, very few interventions were accompanied by comprehensive needs assessment, impact evaluation and workplace policy initiatives. Most interventions were curative-provisioning counseling services, limiting the scope of mental health promotion activities. Addressing mental health wellbeing comprehensively and aligning an organization's policies are crucial. Research on employee mental health, its risk factors, and cost-effectiveness analysis of workplace mental health interventions in the Indian context need to be prioritized.

Third International Conference on Medical Education and Medical writing, University of Karbala College of Medicine, Karbala, Iraq.

University of Karbala College of Medicine (UKCM), Iraq, conducted a three days' workshop on Medical Education and medical writing. The UKCM is now transforming to conform with the latest trends of modern education. This will help to re-shape the future of medical education and produce capable doctors. This requires a strong faculty, which is sound in teaching, training, learning improvement, research capacity building, and leadership development. The capacity building of faculty at UKCM has been initiated in collaboration with Medics International at a local and government level and includes a series of workshops and online symposia. This educational activity was conducted after a delay of three years due to COVID-19. A three -day refresher course was conducted in the first week of August, 2022. Medical writing is another important feature which has been continuously covered by UKMM since many years with the collaboration of Al-Sadiq International Virtual University (SIVU) and Imamia Medics International (IM).

Victim Behavior in a Sample of Military Sexual Assault Cases.

This study explored victim responses to sexual assault within a military context. Victim behavior was identified in forensic case files of service members charged with sexual assault (N = 58) and referred for forensic evaluation or consultation. The identified victim behavior was coded and quantified for description. Of the sample 87.9% of victims were female and 12.0% of victims were male; 37.9% of the victims reported their assault in less than 1 month. Forceful resistance to the assault occurred in 15.5% of the cases. Physical injury associated with the sexual assault was absent in 96.5% of the cases. The description of victim behavior can inform forensic expert testimony on victim behavior within the military justice system while also offering empirical evidence to better understand this public health problem in the U.S. military.

Factors and Interactions Influencing Direct Observation: A Literature Review Guided by Activity Theory.

PhenomenonEnsuring that future physicians are competent to practice medicine is necessary for high quality patient care and safety. The shift toward competency-based education has placed renewed emphasis on direct observation via workplace-based assessments in authentic patient care contexts. Despite this interest and multiple studies focused on improving direct observation, challenges regarding the objectivity of this assessment approach remain underexplored and unresolved. Approach: We conducted a literature review of direct observation in authentic patient contexts by systematically searching databases PubMed, Embase, Web of Science, and ERIC. Included studies comprised original research conducted in the patient care context with authentic patients, either as a live encounter or a video recording of an actual encounter, which focused on factors affecting the direct observation of undergraduate medical education (UME) or graduate medical education (GME) trainees. Because the patient care context adds factors that contribute to the cognitive load of the learner and of the clinician-observer we focused our question on such contexts, which are most useful in judgments about advancement to the next level of training or practice. We excluded articles or published abstracts not conducted in the patient care context (e.g., OSCEs) or those involving simulation, allied health professionals, or non-UME/GME trainees. We also excluded studies focused on end-of-rotation evaluations and in-training evaluation reports. We extracted key data from the studies and used Activity Theory as a lens to identify factors affecting these observations and the interactions between them. Activity Theory provides a framework to understand and analyze complex human activities, the systems in which people work, and the interactions or tensions between multiple associated factors. Findings: Nineteen articles were included in the analysis; 13 involved GME learners and 6 UME learners. Of the 19, six studies were set in the operating room and four in the Emergency department. Using Activity Theory, we discovered that while numerous studies focus on rater and tool influences, very few study the impact of social elements. These are the rules that govern how the activity happens, the environment and members of the community involved in the activity and how completion of the activity is divided up among the members of the community. Insights: Viewing direct observation via workplace-based assessment through the lens of Activity Theory may enable educators to implement curricular changes to improve direct observation of assessment. Activity Theory may allow researchers to design studies to focus on the identified underexplored interactions and influences in relation to direct observation.

Determinants of Respirable Quartz Exposure Concentrations Across Occupations in Denmark, 2018.

BACKGROUND: High concentrations of respirable quartz have been reported from workers in construction, foundries, and quarries. Current exposure concentrations in prevalent but presumably lower exposed occupations have been less examined. We aimed to quantify current exposure concentrations of respirable dust and quartz across prevalent occupations and to identify determinants of respirable quartz exposure across these occupations. METHODS: One hundred and eighty-nine full-shift personal samples of respirable dust of workers within 11 occupations in Denmark were sampled during 2018. Respirable dust was determined gravimetrically and analysed for quartz content with infrared spectrometry. Determinants for respirable quartz exposure, i.e. use of power tools, outdoor or indoor location, and percentage of quartz in respirable dust, were analysed in linear mixed effect models. RESULTS: The overall geometric means (geometric standard deviations) for respirable dust and quartz were 216 µg m-3 (4.42) and 16 µg m-3 (4.07), respectively. The highest quartz concentrations were observed among stone cutters and carvers [93 µg m-3 (3.47)], and metal melters and casters [61 µg m-3 (1.71)]. Use of power tools increased exposure concentrations of quartz by a factor of 3.5. Occupations explained 27%, companies within occupations 28%, and differences between workers within companies within occupations 14% of the variability in quartz concentrations. Thirty percent was due to day-to-day variability in exposure concentrations. In total, 19% of the variation in quartz concentration could be explained by type of tool, indoor/outdoor location, and percentage of quartz in respirable dust. CONCLUSION: Current exposure concentrations are generally low, but some occupations in this study had average exposure concentrations to respirable quartz above the ACGIH threshold limit value of 25 µg m-3. Preventive measures to lower excess risk of quartz-related diseases among these workers are still needed. In terms of preventive strategies, use of power tools and quartz content of used materials were identified as main determinants of exposure. Lowering of exposures will be most efficient when focussed on these major determinants, e.g. tool dust control with water, dust extraction, and use of low quartz content materials.
