Learning Retention in Radiograph Interpretation

Status Completed

Clinical Trial Summary

Learning retention after the deliberate practice of radiograph interpretation may be challenging for image types which are common enough to be clinically relevant but not so common that proficiency can be sustained through clinical practice. This is especially relevant for radiographs such as paediatric elbow films (EXR) that carry high risks for the patient if pathology is missed. Building on prior research in this area, this study will develop an innovative computer learning application for paediatric EXR interpretation. After an initial learning period, this study will quantitatively determine the rate of skill decay and the optimal timing for refresher-education.

Clinical Trial Description

Objectives Learning retention after the deliberate practice of radiograph interpretation may be challenging for image types which are common enough to be clinically relevant but not so common that proficiency can be sustained through clinical practice. This is especially relevant for radiographs such as paediatric elbow films (EXR) that carry high risks for the patient if pathology is missed. Building on our prior research in this area, this study will develop an innovative computer learning application for paediatric EXR interpretation. After an initial learning period, this study will quantitatively determine the rate of skill decay and the optimal timing for refresher-education. Design A prospective cohort design with purposive sampling will be used to develop the EXR education intervention. A four arm randomized control trial will be used to test for the outcomes of skill decay and optimal timing of refresher education. Setting The education intervention will be developed at two tertiary care children's hospitals. Study participants will include physicians from two large paediatric education networks in the United States (Paediatric Outcomes in Simulation Education) and Canada (Paediatric Emergency Research Canada). Statistical analysis For the primary analysis, a four-group multi-level model with time-points nested within participants will be used. Secondary analyses will include a time series approach within each block of 20 test EXR to check for sequential effects, and between each block to determine whether we can efficiently model skill decay curves that can separate the underlying learning attrition curve from the effects of "boluses" of education. Conclusion This study anticipates that learners will increase their learning of elbow radiographs by participating in the deliberate practice of radiographs, with skill decay over time that will be mitigated by refresher education. The results will allow evidence based recommendations regarding refresher education for learning from item banks of radiographs. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
