Enhancing radiology training for medical students

An evidence-based case study on improving nasogastric tube position skills

BACKGROUND

A skill new doctors must acquire is the ability to safely interpret nasogastric (NG) tube chest X-rays. NG tubes are often inserted for patient feeding and chest x-rays are then performed to check the position. Incorrect interpretation of these x-rays can lead to severe complications for the patient. Unfortunately, dedicated training in this skill is often lacking at medical school.

To address this training gap, we collaborated with The Student Radiologist, a free online radiology learning resource for medical students.

APPROACH

By combining our expertise in anatomical illustration, radiology education and digital design, we developed a comprehensive, interactive training module focussed on how to identify a correctly positioned NG tube.

Using bitesize training vignettes, supported by real-life x-rays, the module aimed to provide students with an understanding of the relevant anatomy, a systematic approach to interpretation, and the opportunity to hone their skills on practice cases.

To assess the effectiveness of the training we incorporated test cases, and recruited a cohort of fourth- and fifth-year medical students to the programme. Each cohort completed an anonymous NG tube assessment twice, with only one cohort having access to the NG tube training module in-between.
