Randomized Controlled TrialPart versus whole: a randomized trial of central venous catheterization education.
Central venous catheterization (CVC) is a complex but commonly performed procedure. How best to teach this complex skill has not been clearly delineated. We conducted a randomized trial of the effects of two types of teaching of CVC on skill acquisition and retention. ⋯ Participants in the part-task group outperformed the whole-task group in skill acquisition (2.2 ± 0.8 vs 1.3 ± 1.0; g = 1.01; p = 0.04) and in skill retention (1.5 ± 0.7 vs 0.5 ± 0.8; g = 1.39; p = 0.006) using the global rating scale. Scores rated by the checklist were not significantly different (52.0 ± 25.3 vs 43.5 ± 23.4; g = 0.33; p = 0.47 for skill acquisition; and 48.5 ± 34.9 vs 41.1 ± 20.4; g = 0.35; p = 0.44 for skill retention). For teaching ultrasound-guided CVC to novice learners, teaching in part is preferable than teaching in whole.

Why verifying diagnostic decisions with a checklist can help: insights from eye tracking.
Making a diagnosis involves ratifying or verifying a proposed answer. Formalizing this verification process with checklists, which highlight key variables involved in the diagnostic decision, is often advocated. However, the mechanisms by which a checklist might allow clinicians to improve their verification process have not been well studied. ⋯ Checklist use was associated with enhanced analytic scrutiny in all eye tracking measures assessed (F 6,10 = 6.0, p = .02). In this experiment, using a key variable checklist to verify diagnostic decisions improved error detection. This benefit was associated with enhanced analytic scrutiny of those key variables as measured by eye tracking.

Historical ArticleCost in medical education: one hundred and twenty years ago.
The first full paper that is dedicated to cost in medical education appears in the BMJ in 1893. This paper "The cost of a medical education" outlines the likely costs associated with undergraduate education at the end of the nineteenth century, and offers guidance to the student on how to make financial planning. Many lessons can be gleaned from the paper about the cost and other aspects of nineteenth century medical education. ⋯ The paper encourages the reader to reflect on what has and has not changed in this field since 1893. Modern medical education is still expensive; its expense deters students; and we have only started to think about how to control costs or how to ensure value. Too much of the cost of medical education continues to burden students and their families.

Observational StudyCreating learning momentum through overt teaching interactions during real acute care episodes.
Clinical supervisors fulfill a dual responsibility towards patient care and learning during clinical activities. Assuming such roles in today's clinical environments may be challenging. Acute care environments present unique learning opportunities for medical trainees, as well as specific challenges. ⋯ None of the acute care episodes encountered in the critical care environment represented ideal conditions for learning. Yet, clinical supervisors and trainees succeeded in engaging in overt teaching interactions during many episodes. The educational value of these overt teaching interactions should be further explored, as well as the impact of interventions aimed at increasing their use in acute care environments.
