Foundation year one (FY1) doctors are required to confirm correct placement of nasogastric (NG) feeding tubes on chest radiography on a regular basis. Many FY1s do not receive formal training during medical school or during the FY1 year. Multiple incidents of harm to patients, including death, resulting from incorrect placement of an NG feeding tube have been reported to the National Patient Safety Agency (NPSA) since 2005. Our audit assessed the confidence and knowledge of FY1 doctors in correctly confirming NG placement using a qualitative questionnaire. The results showed that both confidence and knowledge on the topic were remarkably poor. Our intervention consisted of a teaching session to the FY1 cohort, which included information on NPSA guidelines for identifying correct NG placement. A post-teaching questionnaire was attained from the same group of FY1s. Confidence and knowledge of the criteria had significantly improved. We concluded that there is clearly a need for teaching on this subject at an undergraduate and post-graduate level. The interactive peer-led style of our teaching session was shown to be highly effective. The addition of handouts and posters in the clinical workplace acted as helpful reminders for junior doctors to use at the point of need. Our project has highlighted a gap in training which poses a serious potential risk to patient safety. We have created a simple solution which, if adopted on a local and national scale, will facilitate a reduction in avoidable harm to patients.
