Stress and value: the student perspective on utilizing real vs. actor patients in objective structured clinical examinations.

BACKGROUND: Studies have shown objective structured clinical examinations (OSCEs) to be one of the most reliable tools in assessing clinical performance; however in Pediatrics they primarily use manikins, simulators or parent actors which limits the comprehensiveness of the assessment. In our Pediatric Clerkship, medical students are evaluated using a standardized rubric during a clinical evaluation exercise (CEX) with real patients. This study assessed medical students' perceived stress levels and the educational value of the CEX compared an OSCE. We hypothesized there would be equal stress and value for students with the CEX experience compared to the OSCE. METHODS: Third year students anonymously completed questionnaires after required Pediatric CEX and Internal Medicine OSCE evaluations from July 2016-June 2017. The questionnaire included questions from the Intrinsic Motivation Inventory, a validated tool used to assess feelings of stress and perceived value of an exercise. RESULTS: A total of 147 and 145 questionnaires were completed after the CEX and OSCE. There were no differences between groups regarding levels of "nervousness" (p = 0.543) and "relaxation" (p = 0.055); students felt more "at ease" (p = 0.002) and less "pressure" (p < 0.001) during the CEX. Students perceived the CEX to be more useful and important to improve skills compared to the OSCE for the history taking, physical exam and interpersonal skills. CONCLUSIONS: Our results indicate that the CEX was associated with lower stress levels and had higher perceived value when compared to the OSCE. This study supports the usefulness of incorporating real patients into the clinical evaluation of medical students.

Endotracheal Tube Placement Confirmation with Bedside Ultrasonography in the Pediatric Intensive Care Unit: A Validation Study.

Critically ill patients who are intubated undergo multiple chest X-rays (CXRs) to determine endotracheal tube position; however, other modalities can save time, medical expenses, and radiation exposure. In this article, we evaluated the validity and interrater reliability of ultrasound to confirm endotracheal tube (ETT) position in patients. A prospective study was performed on intubated patients with cuffed ETTs. The accuracy of ultrasound to confirm correct ETT placement in 92 patients was 97.8%. Sensitivity, positive predictive value, and agreement of 97.7, 93.3, and 91.3% were found on comparing ultrasound to CXR findings. Ultrasound is feasible, reliable, and has good interrater reliability in assessing correct ETT position in children.

The Heart's Halo: Caring for Pediatric Pneumopericardium.

Pediatric pneumomediastinum and pneumopericardium (PPC) are rare complications, which can arise from various etiologies. We report a case of pediatric PPC secondary to an asthma exacerbation and discuss relevant diagnostic and management principles. Physicians must be aware of PPC and its implications due to the high mortality rate. PPC patients require close observation with continuous cardiorespiratory and telemetry monitoring, and providers experienced in the management of cardiac tamponade at a center capable of providing cardiothoracic surgical intervention. Time to resolution is multifactorial, but can be achieved promptly with supportive care and treatment of underlying condition.
