Development and evaluation of a brief educational cartoon on trainee clinicians’ awareness of risks of ionising-radiation exposure: a feasibility pre-post intervention study of a novel educational tool to promote patient safety

Abstract

Background Over recent decades, CT scans have become routinely available and are used in both acute medical and outpatient environments. However, there is a small increase in the risk of adverse consequences, including an increase in the risk of both malignancy and cataracts. Clinicians are often unaware of these facts, and this represents a challenge for medical educators in England, where almost 5 million CT scans are done annually. New whiteboard methodologies permit development of innovative educational tools that are efficient and scalable in communicating simple educational messages that promote patient safety.Methods A short educational whiteboard cartoon was developed to explore the prior observation that adolescents under the care of paediatricians had a much lower risk of receiving a CT scan than those under the care of clinicians who care for adults. This explored the risks after receiving a CT scan and strategies that can be used to avoid them. The educational cartoon was piloted on new doctors who were attending induction training at a busy teaching hospital.Results The main output was the educational whiteboard cartoon itself. Before the new medical trainees’ induction, 56% (25/45) had received no formal training in radiation awareness, and this decreased to 26% (6/23) after the exposure to the educational cartoon (p=0.02). At baseline, 60% (27/45) of respondents considered that young females were at highest risk from exposure to ionising radiation, and this increased to 87% (20/23) after exposure to the educational cartoon (p=0.06).Conclusions This proof-of-concept feasibility study demonstrates that whiteboard cartoons provide a novel and feasible approach to efficiently promote patient safety issues, where a short succinct message is often appropriate.
