Brief 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.

Outcome Measures

Primary Outcomes (1)

• Accuray

  The percent of cases that were diagnosed correctly by the study participants

  12 months after learning intervention

Secondary Outcomes (2)

• Accuracy

  2, 4, 6, 8, 10 months

• Experience Curve

  12 months

Study Arms (4)

Learning and Assessment at 12 months

NO INTERVENTION

Study participants will complete an 80 case learning set followed by a 20-case post test. The study intervention in this group is a 20-case test at 12 months.

Testing Every Two Months

EXPERIMENTAL

Study participants will complete an 80 case learning set followed by a 20-case post test. Study participants in this group will receive the following study interventions: 20-case post tests without any feedback at 2, 4, 6, 8, 10, 12 months.

Other: Testing

Low Bolus Feedback

EXPERIMENTAL

Study participants will complete an 80 case learning set followed by a 20-case post test. Study participants in this group will receive the following study interventions: 20-case post tests at 2, 4, 6, 8, 10, 12 months. At 6 months, the 20-case post-test will be delivered with feedback.

Other: Testing

High Bolus Feedback

EXPERIMENTAL

Study participants will complete an 80 case learning set followed by a 20-case post test. Study participants in this group will receive the following study interventions: 20-case post tests at 2, 4, 6, 8, 10, 12 months. At 4, 8, and 12 months, the 20-case post-test will be delivered with feedback.

Other: Testing

Model Details: This was a four arm randomized control trial. All participants completed an 80-case deliberately practiced learning set of pediatric elbow radiographs followed by an immediate 20-case post-test. Following this, Group 1 had no testing until 12 months; Groups 2, 3, and 4 had testing (20 cases without feedback) every 2 months until 12 months, but Group 3 also had refresher education (20 cases with feedback) at six months while Group 4 had refresher education at two, six, and ten months.
