does it deliver the benefit?

Baselining / benchmarking the benefit of PACS and SR
• PACS is a good thing
• How good?
Key measurable:
Report turnaround times
Background
• Medium size (620 bed) DGH
• 1st wave implementer in NWWM cluster
• GE PACS interfaced to a legacy RIS / EPR (Meditech)
• Speech recognition:
– a TalkingPoint application – powered by Dragon Naturally Speaking– foreground correction
• Drives the RIS via scripting
Method:
Evaluation of turnaround time from
image taken by Radiographer
(verified on PACS) to electronically
signed (completed on PACS)
• Pre PACS / post PACS
• SR users / non SR users
Method:
Evaluation of turnaround time by Stages:
a) ordered b) image taken (verified on PACS) c) electronically signed (completed)
• Pre PACS / post PACS
• SR users / non SR users
Variables:
• Pre-PACS; 10 Radiologists: post-PACS; 9 Radiologists
• Increase in demand – notably CT
