14. VR controversy
15. VR controversy Radiologists view Increased dictation time
Increased error rate vs. good transcriptionist
Removes focus on images
16. VR controversy accuracy rate Is 95% acceptable?
90% of all reports have errors prior to sign off
10 % of reports have errors with transcriptionists
J Digit Imaging Jun 2007
17. VR economically justified? Decreased Radiologist productivity
50% longer dictation time
24% shorter reports
J Digit Imaging Jun 2007
18. VR economically justified? Replacing lower paid transcriptionists with highly paid physicians
Greater Radiologist productivity ? transcriptionists more cost effective than VR
which course of action makes the most economic sense is not always obvious.

83. Templates disadvantages Takes eyes of the image
May forget to delete non-relevant text
84. Templates Especially useful for repetitive boilerplate
Biopsy
Angiography The patient was placed on the CT table in [<supine> ] position.
Initial scans were obtained to localize the [ ].
An appropriate site at the [ ] was marked.
The patient was prepped and draped in the usual sterile manner. Local anesthesia was achieved with infiltration of 1% Xylocaine.
85. Template approaches Few general reports
Fill in the blanks
Default fill in the blanks
Many specific reports Case [ ]. [ ]
There is no evidence of fracture, dislocation, or bony destruction.
[<The joint spaces are within the limits of normal.>]
[ < >]
Impression:
[<Negative examination.>]
86. Templates itemized reports Lungs: [<normal.>]
Pleura: [<normal.>]
Mediastinum [<normal.>]
Hila: [<normal.>]
Other: [< >]
Comparison: [<None.>]
Impression: [<normal>]
87. Template tricks Standardize template naming convention
Modality ? body part ? side, technique
88. Template tricks Make template easy to change on the fly
Liberal use of paragraphs Case [ ].
Ultrasound abdominal aorta.
Real-time ultrasound examination of the abdominal aorta was obtained in transverse and longitudinal projections.
The patient [<does not have an>] abdominal aortic aneurysm.
The abdominal aorta measures [ ] cm in maximal diameter.
[< >]
Impression:
[<The patient does not have an abdominal aortic aneurysm.>]
