Abstract

PURPOSE: Poster presentations are a popular method of displaying information at conferences and are used increasingly for teaching. Digital media, however, allows for wider dissemination and rapidly bridges the divide between creation and implementation into practice of new medical technologies. The purpose of this project was to develop an educational tool using digital media in order to assist practitioners in the strategy, planning and performance of endobronchial ultrasound -transbronchial needle aspiration (EBUS-TBNA).

METHODS: CT coronal or sagittal images of lymph node (LN) stations 2R, 2L, 4R, 4L, 7, 10R, 10L, 11R and 11L were selected from nine patients. Images were captured using an EBUS (Olympus BF-UC 260F) bronchoscope. Using an inanimate airway model (Armstrong Medical, USA) videobronchoscopy captured images of the EBUS scope at specific reference points for nodal sampling. An IASLC -based LN map was inserted. A focus group comprised of Japanese, European, South and North American experts provided input resulting in minor changes. A Likert- scale pilot survey of 10 chest physicians was conducted to measure usefulness, accuracy and readability.

RESULTS: Three images are displayed showing CT, bronchoscopy and EBUS findings at each nodal station. Focus group input resulted in uniform legends, arrows and incorporation of the boundary line between the right- and left-sided levels 2 and 4 lymph nodes. Surveys revealed uniform agreement in usefulness, accuracy and readability.

CONCLUSION: Digital media were used to design and develop an educational tool pertaining to a minimally invasive diagnostic modality (EBUS-TBNA). This tool involves a combination of radiographic, bronchoscopic and acoustic imaging platforms.

CLINICAL IMPLICATIONS: This tool can potentially be used to assist health care providers introduce EBUS-TBNA into their practice. The digital format allows a wide dissemination using a combination of social media thereby facilitating the global transfer of knowledge.
