Image quality and technical limitations in emergency department cardiac point-of-care ultrasound: A retrospective cohort study

OBJECTIVE

To assess the image quality and common technical limitations seen on cardiac point-of-care ultrasound (POCUS) performed and archived in a single New Zealand ED.

METHODS

A retrospective cohort study of clinically indicated cardiac POCUS, archived from 1 October 2019 to 20 May 2020. Archived examinations were retrospectively reviewed by an ED POCUS expert, and an expert cardiac sonographer to determine diagnostic image quality, technical limitations present and opportunities for image quality improvement. Image quality of credentialed examinations was compared to uncredentialed examinations and examinations that were undocumented in the medical record.

RESULTS

A total of 211 cardiac POCUS examinations were included. The impact of image quality on diagnostic interpretation was only documented in <2% of examinations. There was no difference in median global image quality scores for uncredentialed and credentialed examinations (8.5 vs 9, P = 0.55) and median score for undocumented examinations (5.5) was lower than credentialed examinations (P < 0.01). Common technical limitations identified were off-axis imaging and artefacts limiting image quality.

CONCLUSION

In the present study of clinically indicated cardiac POCUS, low image quality was common but the impact of image quality on diagnostic interpretation was very rarely documented in the medical record. Local quality assurance and training should be directed at credentialed and uncredentialed clinicians including strategies to improve off-axis imaging and managing artefacts where possible. Standardised documentation of image quality that may impact diagnostic accuracy should be encouraged.

Finding Themselves, Their Place, Their Way: Uncertainties Identified by Medical Students

Phenomenon: Navigating uncertainty is a core skill when practicing medicine. Increasingly, the need to better prepare medical students for uncertainty has been recognized. Our current understanding of medical students' perspectives on uncertainty is primarily based on quantitative studies with limited qualitative research having been performed to date. We need to know from where and how sources of uncertainty can arise so that educators can better support medical students learning to respond to uncertainty. This research's aim was to describe the sources of uncertainty that medical students identify in their education. Approach: Informed by our previously published framework of clinical uncertainty, we designed and distributed a survey to second, fourth-, and sixth-year medical students at the University of Otago, Aotearoa New Zealand. Between February and May 2019, 716 medical students were invited to identify sources of uncertainty encountered in their education to date. We used reflexive thematic analysis to analyze responses. Findings: Four-hundred-sixty-five participants completed the survey (65% response rate). We identified three major sources of uncertainty: insecurities, role confusion, and navigating learning environments. Insecurities related to students' doubts about knowledge and capabilities, which were magnified by comparing themselves to peers. Role confusion impacted upon students' ability to learn, meet the expectations of others, and contribute to patient care. Navigating the educational, social, and cultural features of clinical and non-clinical learning environments resulted in uncertainty as students faced new environments, hierarchies, and identified challenges with speaking up. Insights: This study provides an in-depth understanding of the wide range of sources of medical students' uncertainties, encompassing how they see themselves, their roles, and their interactions with their learning environments. These results enhance our theoretical understanding of the complexity of uncertainty in medical education. Insights from this research can be applied by educators to better support students develop the skills to respond to a core element of medical practice.

Medical students' responses to uncertainty: a cross-sectional study using a new self-efficacy questionnaire in Aotearoa New Zealand

OBJECTIVES

Responding well to clinical uncertainty is a crucial skill for any doctor. To better understand how medical students develop this skill, Social Cognitive Theory can be used to explore students' perceived capability to respond to situations of uncertainty. This study aimed to construct a self-efficacy questionnaire and use it to measure medical students' responses to clinical uncertainty.

DESIGN

A 29-item questionnaire was constructed. For each item, participants rated their confidence in responding to uncertain situations using a scale of 0-100. Data were analysed with descriptive and inferential statistics.

SETTING

Aotearoa New Zealand.

PARTICIPANTS

The questionnaire was distributed to 716 of 852 medical students in second, fourth and sixth year, at the three campuses of the Otago Medical School.

RESULTS

The Self-Efficacy to Respond to Clinical Uncertainty (SERCU) questionnaire was completed by 495 participants (69% response rate) and found to be highly reliable (α=0.93). Exploratory factor analysis confirmed a unidimensional scale. A multiple linear regression model predicted self-efficacy scores from year of study, age, mode of entry, gender and ethnicity, F(11,470) = 4.252, p<0.001 adj. R²=0.069. Male students and those admitted to the programme 3 years postdegree or with significant allied health experience were predicted to have significantly higher self-efficacy scores. Year of study was not a significant predictor of average efficacy scores.

CONCLUSIONS

Our research contributes a novel, highly reliable questionnaire that uses self-efficacy to measure medical student responses to uncertainty. The questionnaire revealed that students' confidence in responding to uncertainty may be more related to their background and life experience than to progression through the curriculum. Medical educators and researchers can use the SERCU questionnaire to obtain a new perspective on how their students respond to uncertainty, inform future research and tailor teaching about uncertainty.

Advice for Constructing a Productive Supervisory Relationship in Education Research

Practical advice is offered for a positive and productive supervisory relationship. Tips to get started include suggestions to consider about possible reasons, assumptions, and expectations for engaging in education research. Once a relationship is established, we emphasise the importance of constructing appropriate research questions, understanding the use of theory, and developing time management strategies. We consider the practicalities of initiating a research project and the reflexivity required to maintain shared expectations. We address potential challenges which may disrupt the research process. Finally, we present a set of reflective prompts for supervisors and students to consider before starting a project together.

Student and Educator Experiences of an Integrated Medical Imaging Curriculum

INTRODUCTION

Medical imaging is integrated across all years in the medical programs at the Medical School, in our country. Little is known about this pedagogical approach from the perspective of those who participate in it. This study investigated how students and educators experience an integrated medical imaging curriculum.

METHODS

One-on-one interviews were conducted with nine educators and three undergraduate medical students and analyzed using a reflexive thematic approach. Educators included radiologists, non-radiologists clinicians, and scientists and health professionals from the medical program.

RESULTS

The integrated medical imaging curriculum appears to be incoherently experienced by educators and students as learning opportunities that were 'everywhere and nowhere'. Teaching events were 'repetitive and patchy' and featured a transmission-oriented pedagogy emphasizing 'exposure and absorption'. Educators expressed paradoxical views of their responsibility for teaching medical imaging reflected in this sentiment: 'I don't teach medical imaging… (but I do)'.

DISCUSSION

When medical imaging is integrated into learning resources and course work across the undergraduate program, it may lose its visibility and importance as a distinct learning area despite its crucial role in medical practice. An integrated curriculum may inadvertently separate knowing about medical imaging from learning to apply medical imaging knowledge in clinical practice.

CONCLUSIONS

Further work is required to construct an integrated medical imaging curriculum that explicitly emphasizes medical imaging learning outcomes, so they are experienced coherently and consistently by medical students and those who prepare them for practice as doctors.

Comparing evaluation responses of an interprofessional education initiative with students in undergraduate nursing and medical programmes

BACKGROUND

Interprofessional education initiatives can be used as effective means to influence students' perceptions of their own and others' roles and interactions as health professionals. There is a need to better understand how interprofessional education learning outcomes are appreciated by students.

AIM

The aims of this study were to describe and compare evaluation feedback from students in undergraduate nursing and medicine programmes about the learning outcomes of an interprofessional education initiative.

METHODS

A mixed methods pre-post-study design was used to collect data using evaluation questions about the initiative and two interprofessional learning outcomes: communication and teamwork. Ratings were analysed with a two-way repeated measures analysis of variance or a t-test. Written responses were analysed using a general inductive approach.

RESULTS

Data from 30 nursing students and 12 medical students were analysed. A noteworthy finding was a significantly higher average rating for nursing students than medicine students before and after the session for the statement about valuing interprofessional learning. Three themes represented comments from both groups: positive experiences, relevance to practice, and learning design issues.

DISCUSSION

Findings were interpreted to indicate that students from both programmes valued the learning outcomes session and was greater at the end of the session. Notably, the perceived value of interprofessional learning was higher for nursing students than medical students before and after the session. This finding may be related to the familiarity nursing students may have with the teaching methods used in the initiative. Further exploration of this finding is needed so educators can better understand how they can provide optimal learning experiences for all students who participate in interprofessional education.

CONCLUSION

Nursing and medicine students appear to value the interprofessional learning outcomes in an undergraduate health professional initiative. However, differences between these two groups of students are an area for further exploration.

Towards a new understanding of uncertainty in medical education

RATIONALE, AIMS, AND OBJECTIVES

Uncertainty is a complex and constant phenomenon in clinical practice. How medical students recognize and respond to uncertainty impacts on their well-being, career choices, and attitudes towards patients. It has been suggested that curricula should do more to prepare medical students for an uncertain world. In order to teach medical students about uncertainty, we need to understand how uncertainty has been conceptualized in the literature to date. The aim of this article is to explore existing models of uncertainty and to develop a framework of clinical uncertainty to aid medical education.

METHOD

A scoping literature review was performed to identify conceptual models of uncertainty in healthcare. Content and inductive analyses were performed to explore three dimensions of clinical uncertainty: sources of uncertainty, subjective influencers and responses to uncertainty.

RESULTS

Nine hundred one references were identified using our search strategy, of which, 24 met our inclusion criteria. It was possible to classify these conceptual models using one or more of three dimensions of uncertainty; sources, subjective influencers, and responses. Exploration and further classification of these dimensions led to the development of a framework of uncertainty for medical education.

CONCLUSION

The developed framework of clinical uncertainty highlights sources, subjective influencers, responses to uncertainty, and the dynamic relationship among these elements. Our framework illustrates the different aspects of knowledge as a source of uncertainty and how to distinguish between those aspects. Our framework highlights the complexity of sources of uncertainty, especially when including uncertainty arising from relationships and systems. These sources can occur in combination. Our framework is also novel in how it describes the impact of influencers such as personal characteristics, experience, and affect on perceptions of and responses to uncertainty. This framework can be used by educators and curricula developers to help understand and teach about clinical uncertainty.

Adapting online education resources to meet the needs of an emergency medicine training programme in a pilot feasibility study

This article was migrated. The article was marked as recommended. Introduction: Online resources are available to enhance emergency medicine training programmes. The aim of this study was to evaluate the feasibility of using online case-based resources created in the United States in a New Zealand emergency medicine training programme. Methods: Evaluation data were collected from junior doctors and educators after they participated in the programme. Data sources included research notes and questionnaire responses. The data were analysed qualitatively using a general inductive approach. Results: Evaluation feedback from 19 junior doctors and 14 educators was interpreted to suggest that the online resource, with minor adaptations, was feasible to use in a New Zealand emergency medicine training programme. Findings indicated that educators were able to modify the materials to modify to meet local requirements, however, the opportunity to include a cultural component was missed. Participants appreciated the case-based format and felt that they established a safe and encouraging learning environment with each other. Participants were able to develop a systematic approach to emergency situations and identify red flags related to deteriorating patients. Discussion and Conclusion: Evaluation findings indicate that adapting an online-sourced curriculum is feasible to educators and acceptable to junior doctors and educators participating in a single New Zealand based Emergency Medicine training program. Educators in other international training settings may find the lessons learned helpful when adapting online resources to address the learning needs of their junior doctors. Next steps are to evaluate the impact of this resource on the knowledge and skills learned by junior doctors and any changes in their care for patients in emergency medicine situations.

Developing leadership skills by participating in a peer-led committee of junior doctors

This article was migrated. The article was marked as recommended. Background. This article uses a case study approach to describe and analyse how a peer-led committee was used to develop leadership skills among junior doctors. Junior doctors are a potentially powerful group of leaders within the healthcare sector, yet more senior staff members may encounter difficulty engaging with this group. Leadership and engagement are essential for optimal functioning of an organisation. Alternatives. Typical methods used to develop leadership skills and promote engagement with leadership activities include higher degrees, short courses, coaching, and experiential learning activities. One alternative can be to use experiential learning that has be informed by situated learning theory and the concept of communities of practice. Solution. A peer-led committee of junior doctors was established using to develop leadership skills and promote engagement with leadership activities. The committee was designed to address five features of a community of practice: mutual engagement, joint enterprise, shared repertoire, learning, and community. This peer-led committee included elected roles and met regularly out of hours over two sites within the Southern District Health Board, New Zealand. Recommendations. This intervention was well-received by junior doctors and has been sustained in the Southern District Health Board. A peer-led committee structured with the features of a community of practice may be useful method for others to use when they seek to promote and support the development leadership skills of junior doctors.

Using Best-Worst Choice Methodology in a Survey of Pharmacists Regarding Pharmacy Practice Skills Teaching

Objective. To conduct a survey of practicing pharmacists in which best-worst choice methodology was used to prioritize pharmacy practice skills for inclusion in a pharmacy curriculum in New Zealand.Methods. A literature search and review of pharmacy curricula were conducted, and the findings were used to develop a best-worst choice survey instrument regarding inclusion of pharmacy practice skills in the pharmacy curriculum. The survey was sent to registered pharmacists and intern pharmacists in New Zealand. Participants were asked to prioritize 16 skills in terms of their importance and relevance to pharmacy practice.Results. Of the 3836 pharmacists invited to participate in the survey, 388 completed the questionnaire. Comprehensive chronic disease management, specialty medications, and medicines use review were the top three prioritized skills. Injections, independent prescribing, and specialty compounding were the skills ranked as having the lowest priority. The pharmacists' gender, age, practice setting, and ethnicity all influenced their skill prioritization. The pharmacists emphasized skills required in their current practice but deemphasized some skills that were emerging professional responsibilities.Conclusion. If curricular reform is to include new skills that are largely unfamiliar to or deemed unimportant by practicing pharmacists, quality assurance of students' experiential education will be needed. Furthermore, preceptor education about changing expectations for pharmacy graduates' skill sets must be adequately developed and implemented to ensure that preceptors provide students with opportunities to practice the full range of skills they will need in practice and provide them with accurate assessment and helpful feedback.

Working together in clinical pathology: An interprofessional education initiative for dentistry, oral health, and medical laboratory science teachers and students

This article was migrated. The article was marked as recommended. Introduction. In the health professional education literature, there is a need for information about the teaching and learning of medical laboratory sciences for clinical practice. The goal of this reflection-on-practice is to describe how an orofacial pathology interprofessional education (IPE) initiative was designed and implemented. Innovation. The designers of this initiative were teachers from dentistry, oral health, and medical laboratory science. The designers used six interprofessional competencies (patient-centred care, role clarification, team functioning, collaborative leadership, communication, and cultural practice) to guide their construction of teaching and learning resources. The initiative required students to work collaboratively with a given patient case to develop a differential diagnosis, prepare a treatment plan, present their case to classmates and staff members, and describe how they worked together to address the orofacial pathology in their case. Evaluation. The designers collected and considered evaluation information including the learning resources used, logistical arrangements for the initiative, and evaluation data from students via an anonymous 10-item questionnaire. Students rated statements that addressed the six interprofessional competencies and provided written comments about the initiative. Outcomes. In general, the 18 students agreed strongly with all statements except for cultural practice. Written comments about the initiative were positive and indicated that students appreciated learning about their own discipline and that of other professionals in the context of providing oral healthcare involving orofacial pathology. What next? Given the acceptability of this initiative to the designers, facilitators, and students, the next step is to consider the feasibility of scaling-up this small voluntary IPE initiative into a permanent component of the dentistry, oral health, and medical laboratory science programmes. Aspects to consider include staffing, scheduling, assessment, and cultural perspectives.

Towards a Definition of Distinction in Professionalism

Phenomenon: Professionalism can be characterized by a particular set of attributes that clinicians demonstrate in practice. Although much has been described on those attributes that define acceptable professionalism, the characteristics that define distinction in professionalism have not yet been well defined. Approach: In this exploratory project, qualitative methods were used to triangulate three sources of data collected from three campuses of one medical school: student assessment summaries, teacher interviews, and an institutional policy. Findings: One hundred-thirty student assessment summaries, eight teacher interviews, and one institutional policy were analyzed. Three characteristics emerged that define distinction in professionalism: improvement of oneself, helping others learn, and teamwork. These characteristics are in addition to students demonstrating a clear minimum standard in all other aspects of professionalism. Insights: Findings from this project offer a first step toward a definition of distinction in professionalism for assessing student performance. The characteristics can be demonstrated by students to varying degrees of proficiency and are potentially achievable by all students. Finally, the characteristics would be required in addition to demonstrating a clear minimum standard of performance in all other aspects of professionalism and cannot be inferred by the absence of negative or unprofessional behaviors. Recognizing that conceptions of professionalism have contextual and cultural influences, the characteristics of distinction identified by this project expand the language available for teachers and learners to discuss professionalism. Teachers may use these characteristics to help inform their teaching, learning, and feedback practices. Students will gain clarity about the expectations regarding their professional behavior.

How do pharmacy students describe decision-making about drug therapy?

This article was migrated. The article was not marked as recommended. Introduction: Therapeutic decision-making is offered as a term to describe the responsibility that pharmacists have as medicines experts for making decisions about drug therapy for individual patients. There is a lack of research describing how pharmacy students learn to make therapeutic decisions. Methods: Qualitative methods were used to interview twelve final-year undergraduate pharmacy students. Data were analysed inductively to identify the steps in the process, the definition, and attitudes students learned about therapeutic decision-making. Results: According to these pharmacy students, the process and definition involve four steps; identifying medicines related problems via differential diagnosis, exploring treatment options, weighing up the options, and making a recommendation. Attitudes were confidence, open-mindedness, and bias awareness. Discussion: These findings align with a proposed model for therapeutic decision-making in pharmacy practice, however, this study did not determine if the students could apply the model in practice. Conclusion: These findings can be used as a benchmark for enhancing the pharmacy curriculum to include decision-making skills about drug therapy for future practice settings.

Evaluation. The designers collected and considered evaluation information including the learning resources used, logistical arrangements for the initiative, and student ratings about interprofessional competencies. Outcomes. In general, the designers felt that they had successfully designed and implemented an IPE initiative that met five of the six interprofessional competencies. The designers did not feel that the cultural practice competency was adequately addressed in this version of the initiative. What next? Given the acceptability of this initiative to the designers, facilitators, and students, the next step is to consider the feasibility of scaling-up this small voluntary IPE initiative into a permanent component of the dentistry, oral health, and medical laboratory science programmes. Aspects to consider include staffing, scheduling, assessment, and cultural perspectives.

Clinical reasoning as a threshold skill

Background: Threshold skills are defined as new ways of thinking about and performing in a discipline. They represent transformed ways of thinking and doing that are pivotal to learners' progress. Our aim was to establish whether clinical reasoning exhibited features of a threshold skill. Methods: Twenty-five final-year medical students were interviewed with a five-question protocol about how they were learning clinical reasoning. Students' responses were analyzed using a deductive method to identify features of threshold skills. Results: Students' descriptions of learning clinical reasoning exhibited five features: transformation, troublesomeness, integration, association with practice, and issues with transferability. Conclusions: Viewing clinical reasoning as a threshold skill is a novel interpretation of its nature and has implications for learning, teaching, and research. Students can be reassured that, although initially troublesome, with practice, they will not only learn the skill but also how to use it more effectively. Teachers can help students to understand that clinical reasoning is difficult to learn and will require time and repeated practice under supervision to develop.

Student experiences of learning clinical reasoning

BACKGROUND

Students find learning clinical reasoning skills challenging. Viewing how students learn clinical reasoning skills from a sociocultural perspective, however, may allow helpful and unhelpful descriptions to be interpreted as experiences that promote or inhibit their participation in and opportunities to co-construct their clinical reasoning skills.

METHODS

This interview study was conducted with 25 Year-6 undergraduate medical students. Interview data were first analysed thematically, and then the findings were analysed with the concepts of participation and co-construction.

RESULTS

The themes identified were: (1) practising with undifferentiated patients; (2) teachers who were willing to make thinking explicit; (3) a lack of independence and involvement; (4) a lack of communication and feedback; and (5) confusion from different sources of information. When further analysed, the themes could be represented as points along a continuum of participating in, and co-constructing, clinical reasoning skills.

DISCUSSION

Clinical educators will find the themes identified from students' experiences learning in a workplace environment helpful for understanding why some students may struggle to develop their clinical reasoning skills. An interpretation of findings from a sociocultural perspective offers a different approach for understanding students' difficulties when learning clinical reasoning: one where students are able to increase their participation in, and co-construction of, clinical reasoning in the context of working collaboratively to provide patient care. Students find learning clinical reasoning skills challenging.

Identifying developmental features in students' clinical reasoning to inform teaching

BACKGROUND

There is increasing evidence that students at different levels of training may benefit from different methods of learning clinical reasoning. Two of the common methods of teaching are the "whole - case" format and the "serial cue" approach. There is little empirical evidence to guide teachers as to which method to use and when to introduce them.

METHODS

We observed 23 students from different stages of training to examine how they were taking a history and how they were thinking whilst doing this. Each student interviewed a simulated patient who presented with a straightforward and a complex presentation. We inferred how students were reasoning from how they took a history and how they described their thinking while doing this.

RESULTS

Early in their training students can only take a generic history. Only later in training are they able to take a focused history, remember the information they have gathered, use it to seek further specific information, compare and contrast possibilities and analyze their data as they are collecting it.

CONCLUSIONS

Early in their training students are unable to analyze data during history taking. When they have started developing illness scripts, they are able to benefit from the "serial cue" approach of teaching clinical reasoning.

Using theory to interpret how senior clinicians define, learn, and teach clinical reasoning

This article was migrated. The article was marked as recommended. Introduction: Dual process theory and script theory have been used to understand and explain how students learn clinical reasoning. This study used these tools to interpret how experienced teachers described their definitions of clinical reasoning, their own history learning about clinical reasoning, and their methods of teaching clinical reasoning. Methods: Interview data from 14 senior clinicians were investigated thematically using a general inductive approach then interpreted using principles and concepts associated with dual process theory and script theory, including the concept of deliberate practice and script consciousness. Results and Discussion: Senior clinicians' definitions of clinical reasoning were consistent with the literature. Few of them recalled being explicitly taught clinical reasoning. They identified teaching as a way to further develop their own clinical reasoning. They taught it opportunistically using an apprenticeship and role-modelling approach in clinical contexts. Their teaching techniques included supervised practice, reflection, think aloud, focused data collection guided by the clinical presentation, and iterative reasoning. Conclusion: Dual process theory, script theory, and the concepts of mindful practice and deliberate practice were found to be useful tools to understand how senior clinicians taught and learned clinical reasoning. These findings are guiding our clinical reasoning curriculum and faculty development programme.
