Network Visualization

A couple of my colleagues have a brief communication in the current JMLA issue (Oct '12) describing the development of a training course on network visualization tools.  Give it a read (PMID: 23133334)!

Spinning RCT Results

According to this PLOS Med article, the source of press spins can be traced to article abstracts:

“Spin” was identified in about half of press releases and media coverage. In multivariable analysis, the main factor associated with “spin” in press releases was the presence of “spin” in the article abstract conclusion. (Source)

Table 1 lists the types of spin the authors identified in their sample of RCT abstracts:

  • No acknowledgement of nonstatistically significant primary outcome
  • Claiming equivalence when results failed to demonstrate a statistically significant difference
  • Focus on positive secondary outcome
  • Focus on inappropriate subgroup
  • Focus on within-group (or over-all within) comparison
  • Nonstatistically significant outcome reported as if they were significant
  • Inadequate claim of safety
  • Inappropriate extrapolation

While the sample is small & the focus is narrow, I can see this being an effective talking point in critical appraisal discussions.

Librarian As Facilitator In A Problem-Based Learning Course

A few colleagues and I recently wrote about our integration in a medical school curriculum (source).  Well - here is a librarian at the University of Buffalo who facilitates a small group as part of a clinically-focused, cased-based dental course.  An intriguing role for librarians, and one that would rely greatly on the strength of the relationship between the school & library.  I can't imagine doing something like this, so kudos to the instructor.

Teaching Cultural Competencies

A fascinating article.  The authors explore biases, otherness, habitus, countertransference, and narrative medicine as frameworks for rethinking cultural competency (specifically within medical curricula, but the implications go much further).

Undergraduate Search Training Is Not Sufficient for EBM Searching

Every so often I come across a paper that suggests students & clinicians perceive themselves to be extremely competent searchers.  And every so often I come across a paper that suggests otherwise.  And every so often I point out such studies on this site (E.g.: Here. Here. Here. And here).  

Now here's one that suggests undergraduate search training does not adequately prepare students for the searches needed in clinical contexts.  (Which is why we have developed such a rigourous training program at Umich).
