    A clinical teaching course for residents improves self-perception about preparation to teach Background: Medical doctors need to be competent to teach patients, their families, students, and the health care team. In a previous study we determined that although the residents attach great importance to have teaching skills, they do not feel prepared to meet this role. Aim: To assess self-perception of learning in a formal course of training how to teach for residents. Material and Methods: In 2004 we implemented the course "Residents as Clinical Teachers", based on the Stanford Faculty Development Center for Medical Teachers Model (SFDC), for residents of a Medical School. Residents of all the post graduate programs were invited to take the course as an elective during the period 2004-2011. At the end of the course each resident completed the pre/post Seminar Series Housestaff/student Questionnaire; assessing perceptions of learning, expressed in a Likert scale from 1-5. Results: The implementation of the course in 111 residents significantly improved self-perception of general preparation for teaching and improved self-perception of preparedness in each educational category. The personal goals most commonly established by participants were on feedback (52,2%), control of session (44%) and communication of goals (40%). Barriers for teaching most frequently identified were lack of time to do clinical teaching (51,3%) and environmental limitations (16,2%). The main impact of the course reported by residents were acquisition of teaching skills or tools for teaching (39,6%), enhancing of motivation (14%), and a richer understanding of teaching principles (14%). Conclusions: A clinical teaching course for residents improves their self-perception of preparation to teach and enhances motivation for clinical teaching. (Rev Med Chile 2012; 140: 1431-1436).

    BACKGROUND: Two models, the Help with the Assessment of Adenopathy in Lung cancer (HAL) and Help with Oncologic Mediastinal Evaluation for Radiation (HOMER), were recently developed to estimate the probability of nodal disease in patients with non-small cell lung cancer (NSCLC) as determined by endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA). The objective of this study was to prospectively externally validate both models at multiple centers.
