Results
73 people were recruited in this study,
of whom 23 were medical students,
20 foundation year (FY) doctors,
18 basic specialist trainees (BST's),
4 higher specialist trainees (HST's) and 8 consultants.
Only 63.2% of the 73 participants attempted the first question to identify the anatomy of the carpal bones,
with only 48.9% giving a correct answer.
Images 2-7 aimed to assess the participants’ ability to tell between normal and abnormal and identify the abnormalitiy. Fig. 8
Combined results for all participants:
The mean precentage of participants with a correct response (i.e.
correctly identified as normal or abnormal) for questions 2 to 7 was 48.4% (range: 26.0 %– 60.3%).
The mean percentage of incorrect answers was 9.8% (range: 1.4% - 35.6%).
Unattempted questions ranged between 31.5% and 47.9% with a mean of 41.8%. Fig. 9
The data was analysed to assess whether those who correctly identified between normal and abnormal could correctly identify the abnormality,
if present.
A mean of 30.1% (range: 6.8% - 46.6%) were capable of correctly identifying the abnormality whilst a mean of 13.0% of the participants (range: 8.2% - 37.0%) managed to note an abnormality but were unable to identify the cause.
A mean 5.3% of the participants (range: 2.7% - 9.6%) were able to identify the presence of an abnormality but did not attempt to explain what the abnormality on the radiograph was.

Results by department:
The highest mean percentage of correct responses for all questions 1 to 7 combined was obtained by the radiology department (71.4%) followed by the A&E (50%),
surgical department (23.8%),
medical department (19.8%) and medical school (12.2%).
The highest mean percentage of unattempted questions was by medical students at 69.2%. Fig. 11
Results by grade of medical hierarchy
The best mean percentage of correct responses was obtained by HST’s at 75.0%.
This was followed by consultants at 62.1%,
BST’s at 46.6%,
foundation doctors at 23.4% and medical students at 12.2%.
The highest mean percentage of unattempted questions was again obtained by medical students at 69.2%. Fig. 12
