Background Venous cannulation is an essential task that allows the intravenous administration of fluids and medications. In the United Kingdom, this task is often performed by newly qualified Foundation Year 1 (FY1) doctors; however, difficulties are commonly encountered. The usage of ultrasound increases the chance of successful cannulation, provided the operator has been trained. Some medical schools now include ultrasound in their undergraduate curricula, though this is far from universal. Methods Forty-eight FY1s received a one-hour teaching session on ultrasound-guided venous cannulation, delivered by near-peer Education Fellows. FY1s completed questionnaires immediately after the teaching session, and a follow-up questionnaire three months later. Findings 44.44% of FY1s felt "fairly" or "very" confident in ultrasound-guided venous cannulation at follow-up, compared to 6.66% before the session. Sixty-three attempts were made in the month before the follow-up survey, compared to six in the month prior to the teaching session. The success rate at follow-up was 60% (38/63), up from 50% (3/6) prior to the session. One third fewer cannulas were escalated to senior doctors (72 vs 48), although there was little change in escalations to anesthetists, from 15 vs 18. FY1s identified the lack of ultrasound machines on the wards as a barrier to using ultrasound-guided venous cannulation more often. Conclusion A short, near-peer teaching session can improve FY1s' confidence, usage, and success rates in ultrasound-guided venous cannulation.
