Article review: Improving case presentations with theater training

by Michelle Lin in Academic Life In Emergency Medicine

"To be or not to be?"What could be more strange on a medical school curriculum than a theater training course? The authors of this study in Medical Humanities innovatively designed a 1-week elective course to help medical students at Mayo Medical School to improve their case presentation skills in partnership with the Guthrie Theater.In this pilot course, seven medical students (six 1st year students, one 4th year student) participated. The learning objectives were:Hear stories: those told by patients, colleagues and in written narrativesIdentify the elements of a narrative, and examine stories for narrative structure Share stories: through case presentations, body movement, storytelling and acting Present a patient’s story with elements of traditional medical presentation and narrativeStudents were evaluated for the following competencies:The cognitive capacity and flexibility needed to evaluate and acquire reliable clinical information. ...

Article review: Self-reflection using blogs

by Michelle Lin in Academic Life In Emergency Medicine

Self-reflection is an unique metacognition learning tool. It is increasingly being used in medical education (another prior blog entry). Traditionally, reflection pieces are writing assignments which are shared amongst peers in faculty-facilitated, small-group discussions.With the advent of new technologies, such as blogs (web-logs), how does blogging one's self-reflection pieces compare to the traditional method?Some of the research questions included:How does the level of reflection evident in student writings compare between the two methods?How do reflective writing themes compare between the two methods?What are student perceptions of their respective assignments?MethodologyInternal medicine clerkships at two different US medical schools over two consecutive blocks were quasi-randomized into the control (written essay) or the experimental (blog) group. Convenience sampling made it possible that each study arm enrolled relatively equal numbers of students between the two sites.Control group: Wrote a single reflective essay, which were shared in 2-hour, faculty-facilitated, face-to-face, small-group discussion.Study group: Wrote 2 blog posts and provided at least 1 comment on a peer's blog post. A faculty member provided online commentary and feedback.The reflection pieces were thematically coded by 2 coders with 91% agreement.ResultsThere were 95 total study participants (control group n=45; study group n=50).Seven themes were found in the reflective writings for the 95 study participants.Being humanisticProfessional behaviourUnderstanding caregiving relationshipsBeing a studentClinical learningDealing with death and dyingThe health care system, quality, safety and public healthBoth study groups demonstrated similar distribution of themes and depths of reflection. Post-clerkship surveys showed that students who were in the control group favored written reflections with face-to-face discussions and the blogging group favored blogging. This means that both approaches are likely effective.Bottom LineBlogging technology provides educators another option where reflections can be shared and discussed.ReferenceFischer MA, Haley HL, Saarinen CL, Chretien KC. Comparison of blogged and written reflections in two medicine clerkships. Medical Education. 2011; 45 (2), 166-75 PMID: 21208262.... Read more »

Paucis Verbis: Outpatient treatment for diverticulitis

by Michelle Lin in Academic Life In Emergency Medicine

The classic teaching for the treatment of diverticulitis includes:Hospital admissionBowel rest (NPO)IV fluidsBroad spectrum IV antibioticsDo ALL patients need to be admitted? There is some early literature suggesting that there is a small sub-population who fare well with outpatient treatment.This article from Annals of EM in the "Best Available Evidence" series summarizes the existing literature well. Plus, I was one of the journal reviewers for the article and am thrilled to see this coming out in print finally.[MS Word] [PDF]See other Paucis Verbis cards.Word of caution: This paper only provides guidelines, based on the limited evidence out there. Still use your common sense. For instance, I'd still admit patients who are elderly (>80 years old) or have evidence of any perforation on CT. If on the fence, admit the patient.Still it's nice to see that the treatment of uncomplicated diverticulitis on an outpatient basis has some supporting literature.ReferenceFriend K, Mills AM. Is Outpatient Oral Antibiotic Therapy Safe and Effective for the Treatment of Acute Uncomplicated Diverticulitis? Annals of Emergency Medicine. 2011 - in early press.

Lessons for a Science Writer from a New York Times Editor's Field Notes on Nonfiction Writing

I recently picked up Francis Flaherty's The Elements of Story in my campus bookstore, as I was browsing and drinking my third cup of coffee in between experiments. Turns out, I made an excellent choice from among those titles I randomly picked off the "Books about Books" shelf. I'm already an impulsive book buyer.... The quote from Library Journal on the cover, "An essential read for both freelance writers and students of journalism" just sealed the deal.... Read more »

You're just a number: introduction to the h-index

by Hadas Shema in Information Culture

Measuring a single scientist's output has always been problematic. Why? First, in order for the statistics to be reliable, the scientist has to produce a considerable publication output and get cited. That takes time. Second, measures like research productivity, number of publications and citations don't always correlates. Measuring the output of journals and universities has been far more reliable than measuring that of one person. Suggested by physicist Jorge Hirsch, h-index (2005) offers an attractive way of quantifying one's scientific output as a single number. The index is defined as:“A scientist has index h if h of his or her Np papers have at least h citations each and the other (Np − h) papers have ≤ h citations each” (Hirsch, 2005).So, if a scientist published at least ten papers, which each were cited at least ten times, her h-index is ten. A zero h-index, on the other hand, says that the scientist perhaps published papers, but is yet to have an actual impact.The h-index is attractive because it takes into account both the number of publications and the number of citations. It isn't phased by "one hit wonders", but favors a body of work that each of its components has at least a certain impact (citations).Problems and disadvantagesWhich database to use? Different databases cover different journals, conferences, etc. Web of Science, for example, has better coverage of STEM than of the humanities, which tend to publish books rather than papers. Using Google Scholar will likely inflate the h-index.You aren't a number! (Or at least, not just *one* number). Reducing scientists to a single number ignores other factors, such as their teaching skills and ability to collaborate. Can an entire career really be described as a single number?Source: PhD ComicsThe age factor: The older the scientist gets, the longer she had to publish and get cited. Younger scientists are at disadvantage with the h-index.Relevance: Since the h-index doesn't decrease, it can't tell whether a scientist is still active and/or where her work is still relevant for others in her field.Since the h-index is a single number, scientists with the same h-index can have very different numbers of papers and citations. In the following table, scientist A and scientists B have the same h-index, but scientist A has far more citations in the overall raw calculation. ... Read more »

Paucis Verbis: International Registry on Aortic Dissection (IRAD)

by Michelle Lin in Academic Life In Emergency Medicine

What do these three people have in common? Lucille Ball (comedienne)Jonathan Larson (wrote the musical "Rent")John Ritter (comedian)They all died from an aortic dissection. We commonly consider this diagnosis for Emergency Department patients presenting with severe chest pain. There is an International Registry on Aortic Dissection which published a retrospective, descriptive study of 464 patients with aortic dissections.I find this list helpful, because it illustrates the fact that the classic signs and symptoms aren't actually very common. Here are some scary examples:A pulse deficit in the carotid, brachial, and femoral arteries is only present 15% of the time. A tearing or ripping quality of pain is present in only 50% of patients.Not all patients have a widened mediastinum or abnormal aortic contour (only 78.7%).[MS Word] [PDF]See other Paucis Verbis cards.ReferenceHagan P et al.
