Purpose/Objective:

Medical professionals require training to qualify for performing medical procedures and periodic retraining to remain qualified. In 2016 our hospital deployed an online environment for (re)training of medical professionals allowing for competence evaluation and registration in a quality passport. Our goal was to apply this online environment to develop and deploy a suite of e-learnings for the training of Radiotherapy Technologists (RTTs) on the evaluation of cone beam CTs (CBCTs) in the context of both the RT workflow and the image-guided radiation therapy (IGRT) traffic light protocols used in our department. These traffic light protocols essentially are a set of treatment-site specific decision making rules for the position verification results and anatomic changes observed on the pre-treatment set up CBCT, that has three possible outcomes: treat (green), treat and consult experts later (orange) and don’t treat, first consult experts (red).

Material/Methods:

E-learnings were developed within the Articulate 360 platform for workplace learning. Each e-learning was developed by a multidisciplinary team consisting of IGRT RTTs, a radiation oncologist and a medical physicist that were experts in the subject covered. All e-learnings were developed using an uniform pre-defined format consisting of a theory and a quiz section. The theory section included information about anatomical and pathological changes, organs at risk (OAR), treatment planning, dose constraints, reference CT, margins, registration parameters, step by step CBCT evaluation and the traffic light protocol. The quiz section consisted of five case studies, with three multiple-choice questions each to examine the application of the theory to the case study. Actual, anonymized clinical cases from our clinic were presented and CBCT volumetric images could be evaluated using separate CBCT viewing software. The questions covered anatomical and pathological changes and traffic light score. A minimum score of 7.5 out of 10 is required for registration of qualification in the quality passport. Currently, reapplication for accreditation is required every 5 years. The compliance rate aim is 95%.

Results:

So far, nine different e-learnings have been developed in our clinic. Six e-learnings each covered a different treatment site: breast, lung, upper GE, lower GE, head and neck, and gynaecology. Three more e-learnings covered general CBCT training, dual registration and library of plans protocols. The RTTs took 1.5 to 2 hours to complete a single e-learning. On average 90% of our 75 RTTs had completed a new
