Teaching mechanical ventilation.

Participants have stated that having actually experienced the modes of the ventilator and the components of weaning parameters, they are better able to understand and manage ventilated patients, as opposed to trying to memorize them as in the past. They also have a much greater appreciation for the discomfort experienced by the ventilated patient. (Most students cannot tolerate a PEEP of 10 centimeters of H2O for more than a few minutes). Many remarked that they are much more tolerant with their agitated, intubated patients because they can now understand their agitation. The session has proved to be an effective teaching tool. It is cost effective, does not take long and is enthusiastically received by the participants who believe they have gained a better understanding of how to properly care for their anxious, intubated patients.

Structured single-observer methods of evaluation for the assessment of ward performance on the surgical clerkship.

This study compares the traditional method (TM) of evaluating ward performance on the surgical clerkship with four structured, single-observer methods (SSOM) of evaluating the clinical skills demonstrated in patient workups, progress notes, physical examination, and technical performance. SSOM differed from TM in preciseness of evaluation criteria, training of evaluator, and amount of direct observation of clinical performance. SSOM appeared to be a more precise measurement instrument than TM and far more sensitive to the detection of clinical improvement. The study documents the significant contribution of a nurse-educator to the evaluation process, as this contribution correlates well with TM yet provides a unique and independent perspective. Finally, SSOM of evaluation correlated significantly with oral examination and the National Board of Medical Examiners (NBME) test results. Addition of SSOM to TM is recommended for clerkship evaluation of ward performance.

Test performance of a local examination at a nonlocal site for evaluation of surgical clerks.

Surgical clerkships frequently use locally prepared examinations or nationally available test item banks as an alternative to Surgery Shelf Examinations from the National Board of Medical Examiners (SSNBME) for student evaluation. This study examines performance of a well-designed, item-analyzed local examination (available nationally through the Association for Surgical Education) at a nonlocal site. A 100-item test with a stratified sample from a 442-item bank was administered to 72 third-year students in addition to the SSNBME. The Pearson product moment correlation coefficient between the two examinations was 0.61 (p less than 0.001). Test performance between the local site and nonlocal site was compared by the Kuder-Richardson formula 20 for subtest reliability (internal consistency) and difficulty index (percent correct responses) and the point biserial correlation coefficient (correlation of a student's performance on one item with performance on the rest of the items) for test item analysis. Data show that despite fair correlation with SSNBME, significant deteriorations in both test item performance and reliability occur with the use of a local examination at a nonlocal site. This likely results from problems with content validity at the nonlocal site. Clerkships that use local examinations or national test bank items are strongly advised to evaluate test performance and revise appropriately before using results for formal student evaluation.
