The inseparability of context and clinical reasoning

Early descriptions of clinical reasoning have described a dual process model that relies on analytical or nonanalytical approaches to develop a working diagnosis. In this classic research, clinical reasoning is portrayed as an individual-driven cognitive process based on gathering information from the patient encounter, forming mental representations that rely on previous experience and engaging developed patterns to drive working diagnoses and management plans. Indeed, approaches to patient safety, as well as teaching and assessing clinical reasoning focus on the individual clinician, often ignoring the complexity of the system surrounding the diagnostic process. More recent theories and evidence portray clinical reasoning as a dynamic collection of processes that takes place among and between persons across clinical settings. Yet, clinical reasoning, taken as both an individual and a system process, is insufficiently supported by theories of cognition based on individual clinicals and lacks the specificity needed to describe the phenomenology of clinical reasoning. In this review, we reinforce that the modern healthcare ecosystem - with its people, processes and technology - is the context in which health care encounters and clinical reasoning take place.

Using Natural Language Processing to Evaluate the Quality of Supervisor Narrative Comments in Competency-Based Medical Education

PURPOSE

Learner development and promotion rely heavily on narrative assessment comments, but narrative assessment quality is rarely evaluated in medical education. Educators have developed tools such as the Quality of Assessment for Learning (QuAL) tool to evaluate the quality of narrative assessment comments; however, scoring the comments generated in medical education assessment programs is time intensive. The authors developed a natural language processing (NLP) model for applying the QuAL score to narrative supervisor comments.

METHOD

Samples of 2,500 Entrustable Professional Activities assessments were randomly extracted and deidentified from the McMaster (1,250 comments) and Saskatchewan (1,250 comments) emergency medicine (EM) residency training programs during the 2019-2020 academic year. Comments were rated using the QuAL score by 25 EM faculty members and 25 EM residents. The results were used to develop and test an NLP model to predict the overall QuAL score and QuAL subscores.

RESULTS

All 50 raters completed the rating exercise. Approximately 50% of the comments had perfect agreement on the QuAL score, with the remaining resolved by the study authors. Creating a meaningful suggestion for improvement was the key differentiator between high- and moderate-quality feedback. The overall QuAL model predicted the exact human-rated score or 1 point above or below it in 87% of instances. Overall model performance was excellent, especially regarding the subtasks on suggestions for improvement and the link between resident performance and improvement suggestions, which achieved 85% and 82% balanced accuracies, respectively.

CONCLUSIONS

This model could save considerable time for programs that want to rate the quality of supervisor comments, with the potential to automatically score a large volume of comments. This model could be used to provide faculty with real-time feedback or as a tool to quantify and track the quality of assessment comments at faculty, rotation, program, or institution levels.

The influence of viewing time on visual diagnostic accuracy: Less is more

BACKGROUND

Understanding the factors that contribute to diagnostic errors is critical if we are to correct or prevent them. Some scholars influenced by the default interventionist dual-process theory of cognition (dual-process theory) emphasise a narrow focus on individual clinician's faulty reasoning as a significant contributor. In this paper, we examine the validity of claims that dual process theory is a key to error reduction.

METHODS

We examined the relationship between a clinical experience (staff and resident physicians) and viewing time on accuracy for categorising chest X-rays (CXRs) and electrocardiograms (ECGs). In two studies, participants categorised images as normal or abnormal, presented at viewing times of 175, 250, 500 and 1000 ms, to encourage System 1 processing. Study 2 extended viewing times to 1, 5, 10 and 20 s to allow time for System 2 processing and a diagnosis. Descriptives and repeated measures analysis of variance were used to analyse the proportion of true and false positive rates (TP and FP) as well as correct diagnoses.

RESULTS

In Study 1, physicians were able to detect abnormal CXRs (0.78) and ECGs (0.67) with relatively high accuracy. The effect of experience was found for ECGs only, as staff physicians (0.71, 95% CI = 0.66-0.75) had higher ECG TP than resident physicians (0.63, 95% CI = 0.58-0.68) in Study 1, and staff had lower ECG FP (0.10, 95% CI = 0.03-0.18) than resident physicians (0.27, 95% CI = 0.20-0.33) in Study 2. In other comparisons, experience was equivocal for ECG FPs and CXR TPs and FPs. In Study 2, overall diagnostic accuracy was similar for both ECGs and CXRs, (0.74). There were small interactions between experience and time for TP in ECGs and FP in CXRs, which are discussed further in the discussion and offer insights into the relationship between processing and experience.

CONCLUSION

Overall, our findings raise concerns about the practical application of models that link processing type to diagnostic error, or to specific diagnostic error reduction strategies.

Crowdsourcing a diagnosis? Exploring the accuracy of the size and type of group diagnosis: an experimental study

BACKGROUND

The consultation process, where a clinician seeks an opinion from another clinician, is foundational in medicine. However, the effectiveness of group diagnosis has not been studied.

OBJECTIVE

To compare individual diagnosis to group diagnosis on two dimensions: group size (n=3 or 6) and group process (interactive or artificial groups).

METHODOLOGY

Thirty-six internal or emergency medicine residents participated in the study. Initially, each resident worked through four written cases on their own, providing a primary diagnosis and a differential diagnosis. Next, participants formed into groups of three. Using a videoconferencing platform, they worked through four additional cases, collectively providing a single primary diagnosis and differential diagnosis. The process was repeated using a group of six with four new cases. Cases were all counterbalanced. Retrospectively, nominal (ie, artificial) groups were formed by aggregating individual participant data into subgroups of three and six and analytically computing scores. Presence of the correct diagnosis as primary diagnosis or included in the differential diagnosis, as well as the number of diagnoses mentioned, was calculated for all conditions. Means were compared using analysis of variance.

RESULTS

For both authentic and nominal groups, the diagnostic accuracy of group diagnosis was superior to individual for both the primary diagnosis and differential diagnosis. However, there was no improvement in diagnostic accuracy when comparing a group of three to a group of six. Interactive and nominal groups were equivalent; however, this may be an artefact of the method used to combine data.

CONCLUSIONS

Group diagnosis improves diagnostic accuracy. However, a larger group is not necessarily superior to a smaller group. In this study, interactive group discussion does not result in improved diagnostic accuracy.

Detection of enteric viruses and SARS-CoV-2 in beach sand

Beach sand harbors a diverse group of microbial organisms that may be of public health concern. Nonetheless, little is known about the presence and distribution of viruses in beach sand. In this study, the first objective was to evaluate the presence of seven viruses (Aichi virus, enterovirus, hepatitis A virus, human adenovirus, norovirus, rotavirus, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)) in sands collected at public beaches. The second objective was to assess the spatial distribution of enteric viruses in beach sand. To that end, 27 beach sand samples from different beaches in Portugal were collected between November 2018 and August 2020 and analyzed for the presence of viruses. At seven beaches, samples were collected in the supratidal and intertidal zones. Results show that viruses were detected in 89 % (24/27) of the sand samples. Aichi virus was the most prevalent (74 %). Noroviruses were present in 19 % of the samples (norovirus GI - 15 %, norovirus GII - 4 %). Human adenovirus and enterovirus were detected in 48 % and 22 % of the samples, respectively. Hepatitis A virus and rotavirus were not detected. Similarly, SARS-CoV-2 in beach sand collected during the initial stages of the pandemic was also not detected. The detection of three or more viruses occurred in 15 % of the samples. Concentrations of viruses were as high as 7.2 log copies (cp)/g of sand. Enteric viruses were found in higher prevalence in sand collected from the supratidal zone compared to the intertidal zone. Human adenovirus was detected in 43 % of the supratidal and 14 % in the intertidal samples and Aichi virus in 57 % and 86 % of the intertidal and supratidal areas, respectively. Our findings suggest that beach sand can be a reservoir of enteric viruses, suggesting that it might be a vehicle for disease transmission, particularly for children, the elderly, and immunocompromised users.

His opportunity, her burden: A narrative critical review of why women decline academic opportunities

OBJECTIVES

This paper stems from a desire to deepen our own understanding of why women might 'say no' when allies and sponsors offer or create opportunities for advancement, leadership or recognition. The resulting disparity between representation by men and women in leadership positions, invited keynote speakers and publication counts in academic medicine is a stubborn and wicked problem that requires a synthesis of knowledge across multidisciplinary literature. Acknowledging the complexity of this topic, we selected a narrative critical review methodology to explore reasons why one man's opportunity might be a woman's burden in academic medicine.

METHODS

We engaged with an iterative process of identifying, reviewing and interpreting literature from Psychology (cognitive, industrial and educational), Sociology, Health Professions Education and Business, placing no restrictions on context or year of publication. Knowledge synthesis and interpretation were guided by our combined expertise, lived experience, consultations with experts outside the author team and these guiding questions: (1) Why might women have less time for career advancement opportunities? (2) Why do women have less time for research and leadership? (3) How are these disparities maintained?

RESULTS

Turning down an opportunity may be a symptom of a much larger issue. The power of social expectations, culture and gender stereotypes remains a resistant force against calls for action. Consequently, women disproportionately take on other tasks that are not as well recognised. This disparity is maintained through social consequences for breaking with firmly entrenched stereotypes.

CONCLUSIONS

Popular strategies like 'lean into opportunities', 'fake it till you make it' and 'overcome your imposter syndrome' suggest that women are standing in their own way. Critically, these axioms ignore powerful systemic barriers that shape these choices and opportunities. We offer strategies that allies, sponsors and peers can implement to offset the power of stereotypes.

Undergraduate Learners' Receptiveness to Feedback in Medical Schools: A Scoping Review

Feedback from educators to learners is considered an important element of effective learning in medical school. While early studies were focused on the processes of providing feedback, recent work has showed that factors related to how learners receive feedback seems to be equally important. Considering that the literature on this topic is new in medical education, and studies are diverse and methodologically variable, we sought to conduct a scoping review to map the articles on receptiveness to feedback, to provide an overview of its related factors, to identify the types of research conducted in this area, and to document knowledge gaps in the existing literature. Using the Joanna Briggs Institute scoping review methodology, we searched four databases (CINAHL, Ovid, PubMed, and Web of Science) and screened 9120 abstracts, resulting in 98 articles for our final analysis. In this sample, 80% of studies on the feedback receiver were published in the last 10 years, and there is a vast variation in the studies' methodologies. The main factors that affect medical students' receptiveness to feedback are students' characteristics, feedback content, educators' credibility, and the learning environment. Feedback literacy is a very recent and rarely used term in medical education; therefore, an important area for further investigation. Lastly, we identified some gaps in the literature that might guide future research, such as studying receptiveness to feedback based on academic seniority and feedback literacy's long-term impacts on learning.

Does allowing access to electronic differential diagnosis support threaten the reliability of a licensing exam?

INTRODUCTION

Newer electronic differential diagnosis supports (EDSs) are efficient and effective at improving diagnostic skill. Although these supports are encouraged in practice, they are prohibited in medical licensing examinations. The purpose of this study is to determine how using an EDS impacts examinees' results when answering clinical diagnosis questions.

METHOD

The authors recruited 100 medical students from McMaster University (Hamilton, Ontario) to answer 40 clinical diagnosis questions in a simulated examination in 2021. Of these, 50 were first-year students and 50 were final-year students. Participants from each year of study were randomised into one of two groups. During the survey, half of the students had access to Isabel (an EDS) and half did not. Differences were explored using analysis of variance (ANOVA), and reliability estimates were compared for each group.

RESULTS

Test scores were higher for final-year versus first-year students (53 ± 13% versus 29 ± 10, p < 0.001) and higher with the use of EDS (44 ± 28% versus 36 ± 26%, p < 0.001). Students using the EDS took longer to complete the test (p < 0.001). Internal consistency reliability (Cronbach's alpha) increased with EDS use among final-year students but was reduced among first-year students, although the effect was not significant. A similar pattern was noted in item discrimination, which was significant.

CONCLUSION

EDS use during diagnostic licensing style questions was associated with modest improvements in performance, increased discrimination in senior students and increased testing time. Given that clinicians have access to EDS in routine clinical practice, allowing EDS use for diagnostic questions would maintain ecological validity of testing while preserving important psychometric test characteristics.

Are we talking about practice? A randomized study comparing simulation-based deliberate practice and mastery learning to self-guided practice

OBJECTIVES

Simulation-based technical skills training is now ubiquitous in medicine, particularly for high acuity, low occurrence (HALO) procedures. Mastery learning and deliberate practice (ML + DP) are potentially valuable educational methods, however, they are resource intensive. We sought to compare the effect of deliberate practice and mastery learning versus self-guided practice on skill performance of the rare, life-saving procedure, a bougie-assisted cricothyroidotomy (BAC).

METHODS

We conducted a multi-center, randomized study at five North American emergency medicine (EM) residency programs. We randomly assigned 176 EM residents to either the ML + DP or self-guided practice groups. Three blinded airway experts independently evaluated BAC skill performance by video review before (pre-test), after (post-test) and 6-12 months (retention) after the training session. The primary outcome was post-test skill performance using a global rating score (GRS). Secondary outcomes included performance time and skill performance at the retention test.

RESULTS

Immediately following training, GRS scores were significantly higher as mean performance improved from pre-test, (22, 95% CI = 21-23) to post-test (27, 95% CI = 26-28), (p < 0.001) for all participants. However, there was no difference between the groups on GRS scores (p = 0.2) at the post-test or at the retention test (p = 0.2). At the retention test, participants in the ML + DP group had faster performance times (66 s, 95% CI = 57-74) compared to the self-guided group (77 s, 95% CI = 67-86), (p < 0.01).

CONCLUSIONS

There was no significant difference in skill performance between groups. Residents who received deliberate practice and mastery learning demonstrated an improvement in skill performance time.

Challenges facing standardised patients representing equity-deserving groups: Insights from health care educators

INTRODUCTION

Health professions training programmes increasingly rely on standardised patient (SP) programmes to integrate equity-deserving groups into learning and assessment opportunities. However, little is known about the optimal approach, and many SP programmes struggle to meet these growing needs. This study explored insights from health care educators working with SP programmes to deliver curricular content around equity-deserving groups.

METHODS

We interviewed 14 key informants in 2021 who were involved in creating or managing SP-based education. Verbatim transcripts were analysed in an iterative coding process, anchored by qualitative content analysis methodology and informed by two theoretical frameworks: sociologic translation and simulation design. Repeated cycles of data collection and analyses continued until themes could be constructed, aligned with existing theories and grounded in empirical data, with sufficient relevance and robustness to inform educators and curricular leads.

RESULTS

Three themes were constructed: (i) creating safety for SPs paid to be vulnerable, (ii) fidelity as an issue broader than who plays the role and (iii) engaging equity-deserving groups. SP work involving traditionally marginalised groups risk re-traumatization, highlighting the importance of (i) informed consent in recruiting SPs, (ii) separating role portrayal from lived experiences, (iii) adequately preparing learners and facilitators, (iv) creating time-outs and escapes for SPs and (v) building opportunity for de-roling with community support.

CONCLUSIONS

SP programmes are well positioned to be allies and advocates to equity-deserving groups and to collaborate and share governance of the educational development process from its outset. SP programmes can support the delivery of curricular content around equity-deserving groups by advocating with curricular leadership, building relationships with community partners, facilitating co-creation and co-delivery of educational content and building safety into simulation.

Evaluating the Construct Validity of Competencies: A Retrospective Analysis

Background

A competency-based framework focuses on alignment between professional standards and assessment design. This alignment implies improved measurement validity, yet it has not been established that competence in one context predicts performance in another context. High-stakes competence assessments offer insights into the relationship between assessment design and competencies.

Methods/Analyses

The internationally educated nurses competency assessment program (IENCAP) was developed at Touchstone Institute in collaboration with the College of Nurses of Ontario (CNO) and includes a 12-station OSCE. Each station evaluated the same 10 competencies. We submitted competency scores to a multi-trait multi-method matrix analysis to evaluate the convergent and discriminant validity of competencies.

Results/Observations

All correlations were significant and positive; however, we did not find evidence of convergent or discriminant validity. Correlations were higher between different competencies evaluated within the same station (mean correlation = 0.60) compared to identical competencies evaluated across different stations (mean correlation = 0.19).

Discussion

The results do not provide evidence of construct validity for competencies. While competency-based approaches emphasize various generalized knowledge, skills, and attitudes, these findings indicate that the clinical context is a major determinant of performance.

Conclusion

The context-dependent nature of competencies requires multiple assessments in varied contexts. Performance on a single competency cannot be determined in a single occasion.

Development of the McMaster Embalming Scale (MES) to assess embalming solutions for surgical skills training

Human cadavers used for surgical training are embalmed using various methods to facilitate tissue storage and longevity while preserving the natural characteristics required to achieve high fidelity functional task alignment. However, there are no standardized means to evaluate the suitability of embalming solutions for this purpose. The McMaster Embalming Scale (MES) was developed to assess the extent to which embalming solutions allow tissues to achieve physical and functional correspondence to clinical contexts. The MES follows a five-point Likert scale format and evaluates the effect of embalming solutions on tissue utility in seven domains. This study aims to determine the reliability and validity of the MES by presenting it to users after performing surgical skills on tissues embalmed using various solutions. A pilot study of the MES was conducted using porcine material. Surgical residents of all levels and faculty were recruited via the Surgical Foundations program at McMaster University. Porcine tissue was unembalmed (fresh- frozen) or embalmed using one of seven solutions identified in the literature. Participants were blinded to the embalming method as they completed four surgical skills on the tissue. After each performance, participants evaluated their experience using the MES. Internal consistency was evaluated using Cronbach's alpha. Domain to total correlations and a g-study were also conducted. Formalin-fixed tissue achieved the lowest average scores, while fresh frozen tissue achieved the highest. Tissues preserved using Surgical Reality Fluid (Trinity Fluids, LLC, Harsens Island, MI) achieved the highest scores among embalmed tissues. The Cronbach's alpha scores varied between 0.85-0.92, indicating a random sample of new raters would offer similar ratings using the MES. All domains except odor were positively correlated. The g-study indicated that the MES is able to differentiate between embalming solutions, but an individual rater's preference for certain tissue qualities also contributes to the variance in scores captured. This study evaluated the psychometric characteristics of the MES. Future steps to this investigation include validating the MES on human cadavers. This article is protected by copyright.

Does a deep learning inventory predict knowledge transfer? Linking student perceptions to transfer outcomes

Students are often encouraged to learn 'deeply' by abstracting generalizable principles from course content rather than memorizing details. So widespread is this perspective that Likert-style inventories are now routinely administered to students to quantify how much a given course or curriculum evokes deep learning. The predictive validity of these inventories, however, has been criticized based on sparse empirical support and ambiguity in what specific outcome measures indicate whether deep learning has occurred. Here we further tested the predictive validity of a prevalent deep learning inventory, the Revised Two-Factor Study Process Questionnaire, by selectively analyzing outcome measures that reflect a major goal of medical education-i.e., knowledge transfer. Students from two undergraduate health sciences courses completed the deep learning inventory before their course's final exam. Shortly after, a random subset of students rated how much each final exam item aligned with three task demands associated with transfer: (1) application of general principles, (2) integration of multiple ideas or examples, and (3) contextual novelty. We then used these ratings from students to examine performance on a subset of exam items that were collectively perceived to demand transfer. Despite good reliability, the resulting transfer outcomes were not substantively predicted by the deep learning inventory. These findings challenge the validity of this tool and others like it.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

OSCE Standard Setting: Three Borderline Group Methods

High-stakes assessments must discriminate between examinees who are sufficiently competent to practice in the health professions and examinees who are not. In these settings, criterion-referenced standard-setting methods are strongly preferred over norm referenced methods. While there are many criterion-referenced options, few are feasible or cost effective for objective structured clinical examinations (OSCEs). The human and financial resources required to organize OSCEs alone are often significant, leaving little in an institution's budget for additional resource-intensive standard-setting methods. The modified borderline group method introduced by Dauphinee et al. for a large-scale, multi-site OSCE is a very feasible option but is not as defensible for smaller scale OSCEs. This study compared the modified borderline group method to two adaptations that address its limitations for smaller scale OSCEs while retaining its benefits, namely feasibility. We evaluated decision accuracy and consistency of calculated cut scores derived from (1) modified, (2) regression-based, and (3) 4-facet Rasch model borderline group methods. Data were from a 12-station OSCE that assessed 112 nurses for entry to practice in a Canadian context. The three cut scores (64-65%) all met acceptable standards of accuracy and consistency; however, the modified borderline group method was the most influenced by lower scores within the borderline group, leading to the lowest cut score. The two adaptations may be more defensible than modified BGM in the context of a smaller (n < 100-150) OSCE.

Validity evidence for the Quality of Assessment for Learning score: a quality metric for supervisor comments in Competency Based Medical Education

BACKGROUND

Competency based medical education (CBME) relies on supervisor narrative comments contained within entrustable professional activities (EPA) for programmatic assessment, but the quality of these supervisor comments is unassessed. There is validity evidence supporting the QuAL (Quality of Assessment for Learning) score for rating the usefulness of short narrative comments in direct observation.

OBJECTIVE

We sought to establish validity evidence for the QuAL score to rate the quality of supervisor narrative comments contained within an EPA by surveying the key end-users of EPA narrative comments: residents, academic advisors, and competence committee members.

METHODS

In 2020, the authors randomly selected 52 de-identified narrative comments from two emergency medicine EPA databases using purposeful sampling. Six collaborators (two residents, two academic advisors, and two competence committee members) were recruited from each of four EM Residency Programs (Saskatchewan, McMaster, Ottawa, and Calgary) to rate these comments with a utility score and the QuAL score. Correlation between utility and QuAL score were calculated using Pearson's correlation coefficient. Sources of variance and reliability were calculated using a generalizability study.

RESULTS

All collaborators (n = 24) completed the full study. The QuAL score had a high positive correlation with the utility score amongst the residents (r = 0.80) and academic advisors (r = 0.75) and a moderately high correlation amongst competence committee members (r = 0.68). The generalizability study found that the major source of variance was the comment indicating the tool performs well across raters.

CONCLUSION

The QuAL score may serve as an outcome measure for program evaluation of supervisors, and as a resource for faculty development.

Comparing the long-term prognosis of myocardial infarction with non-obstructive coronary arteries to myocardial infarction with obstructive coronary artery disease

Background

The long-term survival rates of myocardial infarction with non-obstructive coronary arteries (MINOCA) patients is lower than in the general population. Nevertheless, there are conflicting results regarding the prognosis of MINOCA patients in comparison to myocardial infarction with obstructive coronary artery disease (MI-CAD) patients.

Purpose

The aim of this study was to assess the long-term all-cause mortality of MINOCA patients and compare it to MI-CAD patients.

Methods

Retrospective analysis of 2443 consecutively admitted patients for acute myocardial infarction (AMI), in a single coronary intensive care unit. Only patients with 5 years of follow-up and those who died before the 5-year mark were considered. Patients were divided into two groups according to the presence or absence of obstructive coronary artery disease on angiography (≥50% stenosis). Demographic characteristics, symptoms at presentation, past medical history, laboratory characteristics and medication at discharge were compared using the Mann-Whitney U or χ2 test (according to variable type) to ensure comparability between groups. Five-year all-cause mortality was the target endpoint. Five-year survival was modelled through the Cox proportional hazard regression model. The variable of interest (MINOCA vs MI-CAD) and possible confounders that displayed statistically significant differences in the initial demographic analysis were included in univariable Cox regressions, and those with statistically significant associations were included in a multivariable model. Those that displayed non-significant associations in the multivariable model were subsequently removed until we were left with significant associations only, giving us an adjusted hazard ratio.

Results

Comparison between groups is presented in table 1. MINOCA patients were younger and more often women. They were less likely to have smoking habits, diabetes, or a previous history of AMI. They had a lower Killip class, as well as lower troponin I, serum creatinine and low-density lipoprotein cholesterol at admission. On the other hand, they had higher left ventricular ejection fractions. They were also less likely to have beta-blockers or aspirin prescribed at discharge.

All-cause mortality at 5 years was 13.1% among MINOCA patients and 28.3% among MI-CAD patients, with an unadjusted hazard ratio (HR) of 0.421 (95% CI 0.322–0.550), p&lt;0.001. Adjusting for known confounders, the HR was 0.461 (95% CI 0.261–0.816), p=0.008.

Conclusions

Compared with MI-CAD patients, those with MINOCA were slightly younger and had fewer comorbidities. In spite of having a worse long-term prognosis when compared to the general population, MINOCA patients have a significantly higher 5-year survival rate than MI-CAD patients, even after adjustment of confounding factors.

Ethnic and Racial Differences in Ratings in the Medical Student Standardized Letters of Evaluation (SLOE)

BACKGROUND

The Standardized Letter of Evaluation (SLOE) stratifies the assessment of emergency medicine (EM) bound medical applicants. However, bias in SLOE, particularly regarding race and ethnicity, is an underexplored area.

OBJECTIVE

This study aims to assess whether underrepresented in medicine (UIM) and non-UIM applicants are rated differently in SLOE components.

METHODS

This was a cross-section study of EM-bound applicants across 3 geographically distinct US training programs during the 2019-2020 application cycle. Using descriptive and regression analyses, we examine the differences between UIM applicants and non-UIM applicants for each of the SLOE components: 7 qualifications of an EM physician (7QEM), global assessment (GA) rating, and projected rank list (RL) position.

RESULTS

Out of a combined total of 3759, 2002 (53.3%) unique EM-bound applicants were included. UIM applicants had lower ratings for each of the 7QEM questions, GA, and RL positions. Compared to non-UIM applicants, only some of the 7QEM components: "Work ethic and ability to assume responsibility," "Ability to work in a team, and "Ability to communicate a caring nature," were associated with their SLOE. "Commitment to EM" correlated more with GA for UIM than for non-UIM applicants.

CONCLUSIONS

This study shows a difference in SLOE rating, with UIM applicants receiving lower ratings than non-UIM applicants.

Intrinsic or Invisible? An Audit of CanMEDS Roles in Entrustable Professional Activities

PURPOSE

Postgraduate medical education in Canada has quickly transformed to a competency-based model featuring new entrustable professional activities (EPAs) and associated milestones. It remains unclear, however, how these milestones are distributed between the central medical expert role and 6 intrinsic roles of the larger CanMEDS competency framework. A document review was thus conducted to measure how many EPA milestones are classified under each CanMEDS role, focusing on the overall balance between representation of intrinsic roles and that of medical expert.

METHOD

Data were extracted from the EPA guides of 40 Canadian specialties in 2021 to measure the percentage of milestones formally linked to each role. Subsequent analyses explored for differences when milestones were separated by stage of postgraduate training, weighted by an EPA's minimum number of observations, or sorted by surgical and medical specialties.

RESULTS

Approximately half of all EPA milestones (mean = 48.6%; 95% confidence interval [CI] = 45.9, 51.3) were classified under intrinsic roles overall. However, representation of the health advocate role was consistently low (mean = 2.95%; 95% CI = 2.49, 3.41), and some intrinsic roles-mainly leader, scholar, and professional-were more heavily concentrated in the final stage of postgraduate training. These findings held true under all conditions examined.

CONCLUSIONS

The observed distribution of roles in EPA milestones fits with high-level descriptions of CanMEDS in that intrinsic roles are viewed as inextricably linked to medical expertise, implying both are equally important to cultivate through curricula. Yet a fine-grained analysis suggests that a low prevalence or late emphasis of some intrinsic roles may hinder how they are taught or assessed. Future work must explore whether the quantity or timing of milestones shapes the perceived value of each role, and other factors determining the optimal distribution of roles throughout training.

Malnutrition: a mascaraed and underused prognostic marker in coronary patients

Funding Acknowledgements

Type of funding sources: None.

Background

Malnutrition had been associated with worse prognosis in heart failure (HF) patients, especially in elder. However, this association wasn’t demonstrated in coronary patients, after a ST-segment elevation myocardial infarction (STEMI). We want to evaluate the prognosis value of malnutrition, in elder patients, after a STEMI.

Methods

We conducted a retrospective, observational study of 200 elderly patients (365 years) consecutively admitted with STEMI between 2016 and 2017. At discharge, we applied a validated formula who evaluate nutritional status: "Prognostic Nutritional Index" (PNI), [10 x serum albumin at discharge (g/dL) + 0.005 x total lymphocytes at discharge], whose lowest values were associated with malnutrition. At 1 year follow-up, we evaluated the relation between PNI and major adverse cardiac events (MACE): myocardial infarction (MI), HF hospitalization, cardiovascular (CV) and all-cause death.

Results

Mean age was 74±8 years, 71% (n=149) were male and with multiples risks factors (75% hypertense, 63% with dyslipidemia, 33% diabetes and 11% smokers). At discharge, patients had a mean Left Ventricular Ejection Fraction (LVEF) of 47±8% and a mean PNI of 37±5. Low PNI values (malnutrition) were significant associated with MACE at 1-year [OR 0.87 (95% CI 0.78 to 0.97, p=0.01)], after adjusting for age, sex and LVEF. When evaluated individually, low PNI was associated with more incidence of 1-year HF hospitalization [OR 0.88 (95% CI 0.78 to 0.99, p=0.03)] and all-cause death [OR 0.84 (95% CI 0.75 to 0.95, p=0.004)], after adjusting for age, sex and LVEF, but not with MI and CV death.

Conclusion

Malnutrion associated with other comorbidities inherent to elderly people were associated with MACE, 1-year after STEMI, in this type of population. Thus, we want to draw attention to the importance of evaluating the nutritional status during hospitalization for STEMI, allowing to initiate measures that contribute to its improvement.

Electronic diagnostic support in emergency physician triage: a qualitative study (Preprint)

Background

Not thinking of a diagnosis is a leading cause of diagnostic error in the emergency department, resulting in delayed treatment, morbidity, and excess mortality. Electronic differential diagnostic support (EDS) results in small but significant reductions in diagnostic error. However, the uptake of EDS by clinicians is limited.

Objective

We sought to understand physician perceptions and barriers to the uptake of EDS within the emergency department triage process.

Methods

We conducted a qualitative study using a research associate to rapidly prototype an embedded EDS into the emergency department triage process. Physicians involved in the triage assessment of a busy emergency department were provided the output of an EDS based on the triage complaint by an embedded researcher to simulate an automated system that would draw from the electronic medical record. Physicians were interviewed immediately after their experience. Verbatim transcripts were analyzed by a team using open and axial coding, informed by direct content analysis.

Results

In all, 4 themes emerged from 14 interviews: (1) the quality of the EDS was inferred from the scope and prioritization of the diagnoses present in the EDS differential; (2) the trust of the EDS was linked to varied beliefs around the diagnostic process and potential for bias; (3) clinicians foresaw more benefit to EDS use for colleagues and trainees rather than themselves; and (4) clinicians felt strongly that EDS output should not be included in the patient record.

Conclusions

The adoption of an EDS into an emergency department triage process will require a system that provides diagnostic suggestions appropriate for the scope and context of the emergency department triage process, transparency of system design, and affordances for clinician beliefs about the diagnostic process and addresses clinician concern around including EDS output in the patient record.

Developing the Virtual Resus Room: Fidelity, Usability, Acceptability, and Applicability of a Virtual Simulation for Teaching and Learning

PROBLEM

Physical distancing restrictions during the COVID-19 pandemic led to the transition from in-person to online teaching for many medical educators. This report describes the Virtual Resus Room (VRR)-a free, novel, open-access resource for running collaborative online simulations.

APPROACH

The lead author created the VRR in May 2020 to give learners the opportunity to rehearse their crisis resource management skills by working as a team to complete virtual tasks. The VRR uses Google Slides to link participants to the virtual environment and Zoom to link participants to each other. Students and facilitators in the emergency medicine clerkship at McMaster University used the VRR to run 2 cases between June and August 2020. Students and facilitators completed a postsession survey to assess usability and acceptability, applicability for learning or teaching, and fidelity. In addition, students took a knowledge test pre- and postsession.

OUTCOMES

Forty-six students and 11 facilitators completed the postsession surveys. Facilitators and students rated the VRR's usability and acceptability, applicability for learning and teaching, and fidelity highly. Students showed a significant improvement in their postsession (mean = 89.06, standard deviation [SD] = 9.56) compared with their presession knowledge scores (mean = 71.17, SD = 15.77; t(34) = 7.28, P < .001, with a large effect size Cohen's d = 1.23). Two perceived learning outcomes were identified: content learning and communication skills development. The total time spent (in minutes) facilitating VRR simulations (mean = 119, SD = 36) was significantly lower than time spent leading in-person simulations (mean = 181, SD = 58; U = 20.50, P < .008).

NEXT STEPS

Next steps will include expanding the evaluation of the VRR to include participants from additional learner levels, from varying sites, and from other health professions.

Gender Distribution of Emergency Medicine Podcast Speakers

STUDY OBJECTIVE

Over the past 2 decades, podcasting has become an easy and inexpensive way to disseminate information. Given the increasing importance of podcasts in medicine and medical education, it is important to understand the current status of diverse voices on podcasts. The primary objective of this study was to describe the distribution of women and men as hosts and guest speakers among 3 popular emergency medicine podcasts across a 10-year period. The secondary objective was to evaluate the association between host gender and speaker gender.

METHODS

We performed a retrospective cohort study of the gender distribution of hosts and guest speakers among 3 popular emergency medicine podcasts from July 2011 to June 2021. Data were extracted and their gender determined using pronouns listed in their faculty profiles or using Genderize. The data were presented descriptively using subanalyses by year and the type of speaker. We calculated the odds ratio (OR) with 95% confidence interval (CI) for the likelihood of a single host predicting a speaker's gender.

RESULTS

We identified 2,834 podcasts (n=5,962 speakers), with 964 (16.2%) women and 4,996 (83.8%) men speakers. Among hosts, 10.2% were women and 89.8% were men, whereas among guest speakers, 23.4% were women and 76.5% were men. The distribution of women speakers increased from 9.1% in 2011 to 23.1% in 2021. Having a woman host had an OR of 2.40 (95% CI 1.72 to 3.34) for having a woman guest speaker, whereas having a man host had an OR of 0.42 (95% CI 0.30 to 0.58) for having a woman guest speaker.

CONCLUSION

Among the 3 popular emergency medicine podcasts, there are few women speakers, hosts, and guest speakers; however, the proportion has risen over the past 10 years.

Gender differences in emergency medicine standardized letters of evaluation

OBJECTIVES

The Standardized Letter of Evaluation (SLOE) is a vital portion of any medical student's emergency medicine (EM) residency application. Prior literature suggests gender bias in EM SLOE comparative ranking, but there is limited understanding of the impact of gender on other SLOE components. The study objective was to evaluate the presence of gender differences in the 7 Qualifications for EM (7QEM), Global Assessment (GA), and anticipated Rank List (RL) position. A secondary objective was to evaluate the gender differences in 7QEM scores and their link to GA and anticipated RL position.

METHODS

We performed a cross-sectional study using SLOEs from a subset of United States applicants to three EM residency programs during the 2019-2020 application cycle. We collected self-reported demographics, 7QEM scores, GA, and anticipated RL position. We utilized linear regression analyses and repeated measures ANOVA to evaluate if the relationship between the 7QEM scores, GA score, and anticipated RL position was different for men and women.

RESULTS

2103 unique applicants were included (38.6% women, 61.4% men), with 4952 SLOEs meeting inclusion criteria. The average QEM (2.51 vs. 2.39; p < 0.001), GA (2.68 vs. 2.48; p < 0.001), and RL (2.68 vs. 2.47; p < 0.001) scores were statistically higher for women than men. When exploring the relationship between the 7QEM and GA, Ability to communicate a caring nature to patients was not found to be a statistically significant predictor for men, but it was for women. When exploring the relationship between 7QEM and RL, Commitment to EM was not a significant predictor for men, but it was for women.

CONCLUSIONS

Women scored higher than men on the 7QEM, GA, and anticipated RL position on SLOEs. The 7QEM scores factored differently for men and women.

The Impact of Electronic Data to Capture Qualitative Comments in a Competency-Based Assessment System

Introduction

Digitalizing workplace-based assessments (WBA) holds the potential for facilitating feedback and performance review, wherein we can easily record, store, and analyze data in real time. When digitizing assessment systems, however, it is unclear what is gained and lost in the message as a result of the change in medium. This study evaluates the quality of comments generated in paper vs. electronic media and the influence of an assessor’s seniority.

Methods

Using a realist evaluation framework, a retrospective database review was conducted with paper-based and electronic medium comments. A sample of assessments was examined to determine any influence of the medium on the word count and the Quality of Assessment for Learning (QuAL) score. A correlation analysis evaluated the relationship between word count and QuAL score. Separate univariate analyses of variance (ANOVAs) were used to examine the influence of the assessor's seniority and medium on word count, QuAL score, and WBA scores.

Results

The analysis included a total of 1,825 records. The average word count for the electronic comments (M=16) was significantly higher than the paper version (M=12; p=0.01). Longer comments positively correlated with QuAL score (r=0.2). Paper-based comments received lower QuAL scores (0.41) compared to electronic (0.51; p<0.01). Years in practice was negatively correlated with QuAL score (r=-0.08; p<0.001) as was word count (r=-0.2; p<0.001).

Conclusion

Digitization of WBAs increased the length of comments and did not appear to jeopardize the quality of WBAs; these results indicate higher-quality assessment data. True digital transformation may be possible by harnessing trainee data repositories and repurposing them to analyze for faculty-relevant metrics.

Quality in Standardized Patient Training and Delivery: Retrospective Documentary Analysis of Trainer and Instructor Feedback

Background

An important aspect of developing and maintaining a high-quality standardized patient (SP) program is incorporating quality assurance processes. Trainer and instructor feedbacks are considered critical in achieving these goals. The aim of this study is to determine programmatic and systematic issues in the scope of quality assurance and improvement through trainer and instructor feedback on SP performance. We also presented a logic model based on a synthesis of the current literature to ensure the development and maintenance of a quality management culture in the SP program.

Methods

A retrospective analysis of SP scoring was conducted, and written feedback forms completed by trainers and instructors in a large Canadian university’s SP program were collected. The previous six years (2014-2020) of SP feedback forms in the scope of quality assurance were reviewed and analyzed. Descriptive statistics were utilized to analyze the ratings. Thematic analysis was conducted on the data gathered from the written feedback.

Results

A total of 138 feedback forms were reviewed and analyzed in the study. The mean ratings given by the trainers for feedback and professionalism were 4.27 ± 1.29 and 4.77 ± 0.8, respectively. The mean ratings given by the instructors for knowledge of case information, appropriate responses, and affect were 4.84 ± 0.64, 4.86 ± 0.35, and 4.71 ± 0.76, respectively (from a range of 1 to 5). Four key themes emerged from the written feedback: nonverbal behaviors in simulation activity or feedback sessions, providing feedback from the patient perspective, consistency between role portrayal and scenario, and adapting easily to changing situations.

Conclusions

Component scoring on SP performance did not discriminate individual issues, but the qualitative comments identified certain specific issues. Further research is needed to establish standards of continuous quality improvement (CQI) within an SP program.

MS-222 and Propofol Sedation during and after the Simulated Transport of Nile tilapia (Oreochromis niloticus)

The use of anesthetics has been suggested as a strategy to hamper live fish transport-induced stress. Still, there is insufficient data available on the use of alternative anesthetics to MS-222. This study investigated the use of propofol to mitigate stress in Nile tilapia (Oreochromis niloticus, 143.8 ± 20.9 g and 20.4 ± 0.9 cm) during a 6 h simulated transport. Individuals (n = 7) were divided into three groups: control, 40 mg L-1 MS-222, and 0.8 mg L-1 propofol. A naïve group non-transported was also considered. During the 6 h transport and 24 h after, the response to external stimuli, opercular movements, water quality parameters, behavior, blood hematology and other physiological values, the histopathology of the gills, the quality of the fillet, and oxidative-stress changes in gills, muscle, brain, and liver were evaluated. Propofol increased swimming activity of fish but decreased opercular movements and responses to external stimuli, indicating oscillations of the sedation depth. Water pH and glucose levels increased, while hematocrit (HCT) and lactate decreased in propofol groups at 6 h. At this time-point, MS-222 also induced a decrease in the HCT and lactate levels while increasing cortisol levels. Despite these effects, the stress-related behaviors lessened with anesthetics compared to the control group. After the recovery period, physiological responses normalized in animals from both anesthetic groups, but the control still had high cortisol levels. Overall, propofol is a good alternative for the transportation of this species, showing efficient sedation without compromising health or fillet quality. However, further pharmacodynamics and pharmacokinetics knowledge is required to support its use in aquaculture settings.

Inflammatory, Oxidative Stress, and Apoptosis Effects in Zebrafish Larvae after Rapid Exposure to a Commercial Glyphosate Formulation

Glyphosate-based herbicides (GBH) are the most used herbicides in the world, carrying potentially adverse consequences to the environment and non-target species due to their massive and inadequate use. This study aimed to evaluate the effects of acute exposure to a commercial formulation of glyphosate, Roundup^® Flex (RF), at environmentally relevant and higher concentrations in zebrafish larvae through the assessment of the inflammatory, oxidative stress and cell death response. Transgenic Tg(mpxGFP)i114 and wild-type (WT) zebrafish larvae (72 h post-fertilisation) were exposed to 1, 5, and 10 µg mL^-1 of RF (based on the active ingredient concentration) for 4 h 30 min. A concentration of 2.5 µg mL^-1 CuSO₄ was used as a positive control. Copper sulphate exposure showed effectiveness in enhancing the inflammatory profile by increasing the number of neutrophils, nitric oxide (NO) levels, reactive oxygen species (ROS), and cell death. None of the RF concentrations tested showed changes in the number of neutrophils and NO. However, the concentration of 10 µg a.i. mL^-1 was able to induce an increase in ROS levels and cell death. The activity of antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx)), the biotransformation activity, the levels of reduced (GSH) and oxidised (GSSG) glutathione, lipid peroxidation (LPO), lactate dehydrogenase (LDH), and acetylcholinesterase (AChE) were similar among groups. Overall, the evidence may suggest toxicological effects are dependent on the concentration of RF, although at concentrations that are not routinely detected in the environment. Additional studies are needed to better understand the underlying molecular mechanisms of this formulation.

The role of process mining tools in STEMI networks: where should we build a new primary PCI centre?

Background

In ST-segment elevation myocardial infarction (STEMI), time delay between symptom onset and treatment is critical to improve outcome. The expected transport delay between patient location and percutaneous coronary intervention (PCI) centre is paramount for choosing the adequate reperfusion therapy. The “Centre” region of Portugal has heterogeneity in PCI assess due to geographical reasons.

Purpose

We aimed to explore time delays between regions using process mining (PM) tools.

Methods

We retrospectively assessed the Portuguese Registry of Acute Coronary Syndromes for patients with STEMI from October 2010 to September 2019, collecting information on geographical area of symptom onset, reperfusion option, and in-hospital mortality. We used a PM toolkit (PM4H – PMApp Version) to build two models (one national and one regional) that represent the flow of patients in a healthcare system, enhancing time differences between groups. One-way analysis of variance was employed for the global comparison of study variables between groups and post hoc analysis with Bonferroni correction was used for multiple comparisons.

Results

Overall, 8956 patients (75% male, 48% from 51 to 70 years) were included in the national model (Fig. 1A), in which primary PCI was the treatment of choice (73%), with the median time between admission and primary PCI &lt;120 minutes in every region; “Lisboa” and “Centro” had the longest delays, (orange arrows). Fibrinolysis was performed in 4.5%, with a median time delay &lt;1 hour in every region. In-hospital mortality was 5%, significantly higher for those without reperfusion therapy compared to PCI and fibrinolysis (10% vs. 4% vs. 4%, P&lt;0.001). In the regional model (Fig. 1B) corresponding to the “Centre” region of Portugal divided by districts (n=773, 74% male, 47% from 51 to 70 years), only 61% had primary PCI, with “Guarda” (05:04) and “Castelo Branco” (06:50) showing significant longer delays between diagnosis and reperfusion treatment (orange and red arrows, respectively) than “Coimbra” (01:19) (green arrow); only 15% of patients from “Castelo Branco” had primary PCI. Fibrinolysis was chosen in 10% of patients, mostly in “Castelo Branco” (53%), followed by “Guarda” (30%), with a median time delay of 39 and 48 minutes, respectively. Regarding mortality, PCI and fibrinolysis groups had similar death rates while those patients without reperfusion had higher mortality (5% vs. 3% vs. 13%, P=0.001).

Conclusion

Process mining tools help to understand referencing networks visually, easily highlighting inefficiencies and potential needs for improvement. The “Centre” region of Portugal has lower rates and longer delay to primary PCI partially due to the geographical reasons, with worse outcomes in remote regions. The implementation of a new PCI centre in one of these districts, is critical to offer timely first-line treatment to their population.

Should electronic differential diagnosis support be used early or late in the diagnostic process? A multicentre experimental study of Isabel

Background

Diagnostic errors unfortunately remain common. Electronic differential diagnostic support (EDS) systems may help, but it is unclear when and how they ought to be integrated into the diagnostic process.

Objective

To explore how much EDS improves diagnostic accuracy, and whether EDS should be used early or late in the diagnostic process.

Setting

6 Canadian medical schools. A volunteer sample of 67 medical students, 62 residents in internal medicine or emergency medicine, and 61 practising internists or emergency medicine physicians were recruited in May through June 2020.

Intervention

Participants were randomised to make use of EDS either early (after the chief complaint) or late (after the complete history and physical is available) in the diagnostic process while solving each of 16 written cases. For each case, we measured the number of diagnoses proposed in the differential diagnosis and how often the correct diagnosis was present within the differential.

Results

EDS increased the number of diagnostic hypotheses by 2.32 (95% CI 2.10 to 2.49) when used early in the process and 0.89 (95% CI 0.69 to 1.10) when used late in the process (both p<0.001). Both early and late use of EDS increased the likelihood of the correct diagnosis being present in the differential (7% and 8%, respectively, both p<0.001). Whereas early use increased the number of diagnostic hypotheses (most notably for students and residents), late use increased the likelihood of the correct diagnosis being present in the differential regardless of one’s experience level.

Conclusions and relevance

EDS increased the number of diagnostic hypotheses and the likelihood of the correct diagnosis appearing in the differential, and these effects persisted irrespective of whether EDS was used early or late in the diagnostic process.

Elucidation of fecal inputs into the River Tagus catchment (Portugal) using source-specific mitochondrial DNA, HAdV, and phage markers

Determining the source of fecal contamination in a water body is important for the application of appropriate remediation measures. However, it has been suggested in the extant literature that this can best be achieved using a 'toolbox' of molecular- and culture-based methods. In response, this study deployed three indicators (Escherichia coli (EC), intestinal enterococci (IE) and somatic coliphages (SC)), one culture-dependent human marker (Bacteroides (GB-124) bacteriophage) and five culture-independent markers (human adenovirus (HAdV), human (HMMit), cattle (CWMit), pig (PGMit) and poultry (PLMit) mitochondrial DNA markers (mtDNA)) within the River Tagus catchment (n = 105). Water samples were collected monthly over a 13-month sampling campaign at four sites (impacted by significant specific human and non-human inputs and influenced by differing degrees of marine and freshwater mixing) to determine the dominant fecal inputs and assess geographical, temporal, and meteorological (precipitation, UV, temperature) fluctuations. Our results revealed that all sampling sites were not only highly impacted by fecal contamination but that this contamination originated from human and from a range of agricultural animal sources. HMMit was present in a higher percentage (83%) and concentration (4.20 log GC/100 mL) than HAdV (32%, 2.23 log GC/100 mL) and GB-124 bacteriophage with the latter being detected once. Animal mtDNA markers were detected, with CWMit found in 73% of samples with mean concentration of 3.74 log GC/100 mL. Correlation was found between concentrations of fecal indicators (EC, IE and SC), CWMit and season. Levels of CWMit were found to be related to physico-chemical parameters, such as temperature and UV radiation, possibly as a result of the increasing presence of livestock outside in warmer months. This study provides the first evaluation of such a source-associated 'toolbox' for monitoring surface water in Portugal, and the conclusions may inform future implementation of surveillance and remediation strategies for improving water quality.

Introducing Simulation-Based Learning for Trainees in Chronic Pain Medicine: Needs Assessment and Suggestions for Training Scenarios

INTRODUCTION

Managing patients with chronic pain can be complex and requires specialized clinical knowledge and advanced communication skills. Simulation-based learning has been shown to improve learning outcomes for complex competencies and could be a valuable resource for trainees in chronic pain medicine.

METHODS

We assessed the need for a simulation-based course for trainees in chronic pain medicine at McMaster University in Canada. The needs assessment consisted of three steps: (1) literature review to identify preexisting needs assessments, (2) targeted interviews with six healthcare professionals in chronic pain management, and (3) an analysis of 366 routinely collected patient experience surveys.

RESULTS

The systematic review identified a small body of related literature and no previous needs assessment. We identified the following key competencies and skills that trainees in pain medicine need to develop: (1) communicating with distressed patients using skills such as de-escalation, active listening, and motivational interviewing, (2) managing patients in difficult emotional situations such as poorly controlled pain or showing signs of opioid misuse, and (3) recognizing and managing mental health issues related to chronic pain using appropriate instruments.

DISCUSSION

Suggestions for scenarios included the following: (1) consulting a patient with poor pain control and running out of treatment options, (2) managing a patient with suspected inappropriate opioid use, and (3) diagnosing depression in a patient suffering from chronic pain and developing an appropriate treatment plan.

CONCLUSION

We propose the development of suggested scenarios into simulation-based courses, and test and refine them together with trainees and experts in pain medicine.

Intuitive and deliberative approaches for diagnosing 'well' versus 'unwell': evidence from eye tracking, and potential implications for training

Rapidly assessing how ill a patient is based on their immediate presentation-colloquially termed 'eyeballing' in practice-serves a vital role in acute care settings. Yet surprisingly little is known about how this diagnostic skill is learned or how it should be taught. Some authors have pointed to a dual-process model, suggesting that assessments of illness severity are driven by two distinct types of processing: an intuitive, fast, pattern recognition-like process (Type 1) that depends on many prior patient encounters and outcomes being stored in memory; and a deliberate, slow, analytic process (Type 2) characterized by additional data gathering, data scrutiny, or recollection of rules. But prior studies have supported a dual-process model for the assessment of illness severity only insofar as experienced clinicians chiefly displayed what was presumed to be Type 1 processing. Here we further explored a dual-process model by examining whether less experienced clinicians displayed both types of processing when assessing illness severity across a series of cases. Consistent with the model, a dissociation between Type 1 and Type 2 processing was observed through resident reports of deliberation, response times, and three eye tracking metrics associated with diagnostic expertise. We conclude by discussing potential implications for the training of this enigmatic diagnostic skill.

Late diagnosis of intraplacental choriocarcinoma co-existing with fetomaternal haemorrhage causing fetal demise: A case report

Intraplacental choriocarcinoma (IC) is a rare disease, occurring in approximately 1 in 50,000 pregnancies. A 33-year-old woman, gravida 2 para 0, sustained an intrauterine fetal death due to fetomaternal haemorrhage (FMH) at 36 weeks of gestation after presenting with decreased fetal movements in the days prior. The placenta macroscopically appeared normal. However, histological examination revealed an intraplacental choriocarcinoma. Assessment of this woman's quantitative beta human chorionic gonadotropin (bHCG) level was negative and a computerized tomography scan of her chest, abdomen and pelvis revealed no metastatic disease yet a bulky uterus. After discussion at a multidisciplinary tumour board meeting, the patient had endometrial curettings to rule out any uterine pathology and serial bHCG tests until one year post-partum. Following this, the patient successfully carried and delivered a live female term infant. Although FMH is a rare clinical manifestation of IC it should always alert clinicians to investigate the cause further, through urgent and careful histopathological examination of the placenta. This will allow for appropriate management with chemotherapy if indicated and a reduction in maternal morbidity and mortality.

Do you hear what you see? Utilizing phonocardiography to enhance proficiency in cardiac auscultation

INTRODUCTION

Cardiac auscultation skills have proven difficult to train and maintain. The authors investigated whether using phonocardiograms as visual adjuncts to audio cases improved first-year medical students' cardiac auscultation performance.

METHODS

The authors randomized 135 first-year medical students using an email referral link in 2018 and 2019 to train using audio-only cases (audio group) or audio with phonocardiogram tracings (combined group). Training included 7 cases with normal and abnormal auscultation findings. The assessment included feature identification and diagnostic accuracy using 14 audio-only cases, 7 presented during training, and 7 alternate versions of the same diagnoses. The assessment-administered immediately after training and repeated 7 days later-prompted participants to identify the key features and diagnoses for 14 audio-only cases. Key feature scores and diagnostic accuracy were compared between groups using repeated measures ANOVA.

RESULTS

Mean key feature scores were statistically significantly higher in the combined group (70%, 95% CI 67-75%) compared to the audio group (61%, 95% CI 56-66%) (F(1,116) = 6.144, p = 0.015, d_s = 0.45). Similarly, mean diagnostic accuracy in the combined group (68%, 95% CI 62-73%) was significantly higher than the audio group, although with small effect size (59%, 95% CI 54-65%) (F(1,116) = 4.548, p = 0.035, d_s = 0.40). Time on task for the assessment and prior auscultation experience did not significantly impact performance on either measure.

DISCUSSION

The addition of phonocardiograms to supplement cardiac auscultation training improves diagnostic accuracy and heart sound feature identification amongst novice students compared to training with audio alone.

Myocardial infarction in young adults: are the risk profile and mortality outcomes different from older patients?

Funding Acknowledgements

Type of funding sources: None.

Introduction

The incidence of acute myocardial infarction (AMI) among young patients is increasing. The YOUNG-MI Registry reported that those under 40 years had similar risk profiles and outcomes compared to those aged 41 to 50. We aimed to evaluate cardiovascular risk factors and mortality outcomes in two age cohorts from southern European.

Methods

We retrospectively evaluated 4758 patients admitted to our coronary intensive care unit between 2004 and 2017 with AMI. We only included patients &lt;60 years in two subgroups: cohort A &lt; 50 years and cohort B 50-60 years. 

Results

From the 1233 patients included (mean age 50.5 ± 6.5 years, 82.2% male), 53% had STEMI. Cohort B had higher rates of hypertension (59.8 vs. 42.9%, p &lt; 0.001), diabetes (41.8 vs. 28.9%, p &lt; 0.001), and dyslipidemia (59.4 vs. 46.4%, p &lt; 0.001), while cohort A had higher rates of familial premature coronary artery disease (20.9 vs. 13.2%, p &lt; 0.001) and smoking habits (54.4 vs. 40.0%, p &lt; 0.001). Regarding coronary angiography, cohort B had higher rates of obstructive disease in each epicardial artery, except for left main involvement and non-obstructive disease (Fig. 1). Cohort A had lower all-cause mortality rates at the index hospitalization (1.3 vs. 3.2%, p = 0.045), 6-months (2.9 vs.5.4, p = 0.038), 1-year (3.1 vs. 6.3%, p = 0.014), and 3-years (3.6 vs 8.4, p = 0.001). After multivariable adjustment, we found no relationship between age cohorts and all-cause mortality for any follow-up timing: HR 1.57 (95% CI 0.56-4.37), 1.37 (95% CI 0.50-3.74), and 0.92 (95% CI 0.35-2.39) at 6-months, 1-year, and 3-years, respectively.

Conclusion

Among patients who suffer AMI, those under 50 years old have a different risk profile, compared to the 50-60 years cohort. However, there is no significant difference in all-cause mortality.

Marine algal flora of São Miguel Island, Azores

BACKGROUND

The macroalgal flora of the Island of São Miguel (eastern group of the Azores Archipelago) has attracted the interest of many researchers in the past, the first publications going back to the nineteenth century. Initial studies were mainly taxonomic, resulting in the publication of a checklist of the Azorean benthic marine algae. Later, the establishment of the University of the Azores on the Island permitted the logistic conditions to develop both temporal studies and long-term research and this resulted in a significant increase on research directed at the benthic marine algae and littoral communities of the Island and consequent publications.Prior to the present paper, the known macroalgal flora of São Miguel Island comprised around 260 species. Despite this richness, a significant amount of the research was never made public, notably Masters and PhD theses encompassing information regarding presence data recorded at littoral and sublittoral levels down to a depth of approximately 40 m around the Island and the many collections made, which resulted in vouchers deposited in the AZB Herbarium Ruy Telles Palhinha and the LSM- Molecular Systematics Laboratory at the Faculty of Sciences and Technology of the University of the Azores.The present publication lists the macroalgal taxonomic records, together with information on their ecology and occurrence around São Miguel Island, improving the knowledge of the Azorean macroalgal flora at local and regional scales.

Integrated efforts to promote mental health care during the SARS-CoV-2 pandemic: Reflecting on the experience of a university helpline

Introduction

The SARS-CoV-2 pandemic is affecting numerous dimensions of our society since the beginning of the outbreak. A significant increase in emotional distress was expected in the general population, particularly among the high-risk groups such as the oldest, chronic patients, healthcare professionals, and psychopathology vulnerable people. There was an urgent need to adapt and create solutions to promote mental health. Given the recommendations to minimize face-to-face interactions, several helplines were widely developed.

Objectives

In this work, we aim to reflect on the experience of a university helpline, that integrated efforts with the regional mental health care services.

Methods

A University helpline was created to give support to the regional community outside academia. The team was created on an online teamwork platform, to communicate through the chat, carry videoconference meetings, and store useful files. A Manchester screening decision tree was adopted, to define a set of guidelines to provide support to the callers, based mainly on the guidelines defined by the Order of Portuguese Psychologists. Liaison with the mental health care services, including other specific helplines, was established.

Results

Notwithstanding all the efforts, the number of received calls was scarce, similarly to helplines created by other national universities and by other entities.

Conclusions

A new approach to psychological intervention in crisis is needed, maintaining integrated efforts, and taking advantage of the opportunity to foster personalized mental health care in the digital era. It is important to continuously assess the value of integrated efforts in patient care and to the healthcare system.

"I made a mistake!": A narrative analysis of experienced physicians' stories of preventable error

RATIONALE, AIMS, AND OBJECTIVES

The complexity of healthcare systems makes errors unavoidable. To strengthen the dialogue around how physicians experience and share medical errors, the objective of this study was to understand how generalist physicians make meaning of and grow from their medical errors.

METHODS

This study used a narrative inquiry approach to conduct and analyse in-depth interviews from 26 physicians from the generalist specialties of emergency, internal, and family medicine. We gathered stories via individual interview, analysed them for key components, and rewrote a "meta-story" in a chronological sequence. We conceptualized the findings into a metaphor to draw similarities, learn from, and apply new principles from other fields of practice.

RESULTS

Through analysis we interpreted the story of a physician who is required to make numerous decisions in a short period of time in different clinical environments among the patient's family and whilst abiding by existing rules and regulations. Through sharing stories of success and failure, the clinical supervisor can help optimize the physician's emotional growth and professional development. Similarly, through sharing and learning from stories, colleagues and trainees can also contribute to the growth of the protagonist's character and the development of clinic, hospital, and healthcare system.

CONCLUSION

We draw parallels between the clinical setting and a generalist physician's experiences of a medical error with the environment and practices within professional sports. Using this comparison, we discuss the potential for meaningful coaching in medical education.

Marine algal flora of Santa Maria Island, Azores

BACKGROUND

The algal flora of the Island of Santa Maria (eastern group of the Azores archipelago) has attracted interest of researchers on past occasions (Drouët 1866, Agardh 1870, Trelease 1897, Schmidt 1931, Ardré et al. 1974, Fralick and Hehre 1990, Neto et al. 1991, Morton and Britton 2000, Amen et al. 2005, Wallenstein and Neto 2006, Tittley et al. 2009, Wallenstein et al. 2009a, Wallenstein et al. 2010, Botelho et al. 2010, Torres et al. 2010, León-Cisneros et al. 2011, Martins et al. 2014, Micael et al. 2014, Rebelo et al. 2014, Ávila et al. 2015, Ávila et al. 2016, Machín-Sánchez et al. 2016, Uchman et al. 2016, Johnson et al. 2017, Parente et al. 2018). Nevertheless, the Island macroalgal flora is not well-known as published information reflects limited collections obtained in short-term visits by scientists. To overcome this, a thorough investigation, encompassing collections and presence data recording, was undertaken at both the littoral and sublittoral levels down to a depth of approximately 40 m, covering an area of approximately 64 km2. The resultant taxonomic records are listed in the present paper which also provides information on species ecology and occurrence around the Island, improving, thereby, the knowledge of the Azorean macroalgal flora at both local and regional scales.

NEW INFORMATION

A total of 2329 specimens (including some taxa identified only to genus level) belonging to 261 taxa of macroalgae are registered, comprising 152 Rhodophyta, 43 Chlorophyta and 66 Ochrophyta (Phaeophyceae). Of these, 174 were identified to species level (102 Rhodophyta, 29 Chlorophyta and 43 Ochrophyta), encompassing 52 new records for the Island (30 Rhodophyta, 9 Chlorophyta and 13 Ochrophyta), 2 Macaronesian endemics (Laurencia viridis Gil-Rodríguez & Haroun; and Millerella tinerfensis (Seoane-Camba) S.M.Boo & J.M.Rico), 10 introduced (the Rhodophyta Acrothamnion preissii (Sonder) E.M.Wollaston, Antithamnion hubbsii E.Y.Dawson, Asparagopsis armata Harvey, Bonnemaisonia hamifera Hariot, Melanothamnus harveyi (Bailey) Díaz-Tapia & Maggs, Scinaia acuta M.J.Wynne and Symphyocladia marchantioides (Harvey) Falkenberg; the Chlorophyta Codium fragile subsp. fragile (Suringar) Hariot; and the Ochrophyta Hydroclathrus tilesii (Endlicher) Santiañez & M.J.Wynne, and Papenfussiella kuromo (Yendo) Inagaki) and 18 species of uncertain status (11 Rhodophyta, 3 Chlorophyta and 4 Ochrophyta).

Left atrial functional assessment and mortality in patients with severe aortic stenosis

Funding Acknowledgements

Type of funding sources: None.

Background/Introduction: Aortic valve stenosis (AS) is the most common primary valvular heart disease leading to surgical or percutaneous aortic valve replacement (AVR) in Europe. Both symptoms and systolic dysfunction can appear late in the course of the disease, being often synonym of irreversible damage to the myocardium when found. Thus, there is a necessity to find other sensitive markers present at an earlier stage of the disease. 

Purpose

Our primary aim is to clarify the relationship between LA function measured at severe AS diagnosis (evaluated by means of volumetric assessment) and all-cause mortality during follow-up.

Methods

We retrospectively evaluated patients diagnosed with severe AS for the first time at our echocardiography laboratory. We evaluated all 3 left atrial (LA) functional phases (reservoir, conduit and pump) by measuring LA volumes at different timings of cardiac cycle. Treatment strategy was decided according to heart team consensus and own patient decision. We divided patients into groups according to terciles of LA reservoir, conduit and pump function. Primary outcome was defined by the occurrence of all-cause mortality during follow-up.

Results

After exclusion criteria, a total of 451 patients were included in the analysis (aged 74 ±11years, 54% male) and were followed during a median period of 73 months (interquartile range 44.5). A total of 55.8% of patients underwent AVR and 45,5% of patients registered the primary outcome. Left atrial emptying fraction (LAEF) was the best LA functional parameter in discriminating primary outcome (AUC 0.840, p &lt; 0.001), even when compared to left ventricular ejection fraction, aortic valve area, aortic mean pressure gradient and aortic Vmax. Patients in the lower tercile of LAEF were older, had greater comorbidities, had greater AS severity, with greater degree of diastolic disfunction. After adjustment for clinical and demographic variables, cumulative survival of patients with LAEF &lt;37% and LAEF 37 to 53% relative to patients with LAEF ≥54% remained significantly lower (adjusted HR 19.04, 95% CI 8.30-43.67, P &lt; 0.001 and adjusted HR 4.09, 95% CI 1.85-9.06, P = 0.001). Survival was also higher in patients with LAEF 37 to 53% when compared to patients with LAEF &lt;37% (adjusted HR 0.22, 95% CI 0.13-0.37, P &lt; 0.001). All associations remained true after adjustment for AVR (LAEF &lt;37% versus LAEF 37 to 53% and LAEF ≥54%, respectively, adjusted HR 3.97, 95% CI 1.80-8.78, P = 0.001 and adjusted HR 13.95, 95% CI 5.98-32.54, P &lt; 0.001, respectively)

Conclusion(s) In patients with a first diagnosis of severe AS in hospital setting, LA function assessed by volumetric parameters is an independent predictor of all-cause mortality. Compared to classical severity parameters, different LA functional parameters were found to be more potent predictors of death. These data can be useful in clinical practice for risk stratification and therefore for decision of timing for AVR.
